WO 2006/074378 PCT/US2006/000474 INSULIN AND LEPTIN RESISTANCE WITH HYPERLEPTINEMIA IN MICE LACKING ANDROGEN RECEPTOR 1. This application claims the benefit of U.S. Provisional Application No. 60/642,129 filed January 7, 2005, which is incorporated herein by reference in its entirety. 5 2. This application was made with government support under federal grants NIH DK60905 and DK60948 awarded by the NIH. The Government has certain rights to this invention. I. BACKGROUND OF THE INVENTION 3. Androgen receptor (AR) is a member of the steroid hormone superfamily of 10 nuclear receptors. -Androgen receptor has been implicated in many cancers in an androgen dependent way. Disclosed herein androgen receptor is also involved in the development of Type 11 Diabetes and coronary heart disease (CHD). Furthermore, while antiandrogens, such as hydroxyflutamide have been used to treat AR dependent cancers for many years, these same treatments can increase the factors that contribute to Type II Diabetes and CHD. 15 The disclosed molecules and their interactions between androgen receptor, as well as the information that androgen receptor can have effects on Type If Diabetes and CHD provide for methods of identifying compositions which modulate or mimic this activity, as well as methods of modulating AR activity itself, as well as treatments and modulation of these diseases and the effects of these diseases. 20 II. SUMMARY OF THE INVENTION 4. In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to Type I Diabetes and Coronary Heart Disease (CHD) and related diseases and conditions. 5. It is to be understood that both the foregoing general description and the 25 following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. III. BRIEF DESCRIPTION OF THE DRAWINGS 6. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and together with the 30 description, serve to explain the principles of the invention. 7. Figure 1 shows that AR'S mice developed excess adiposity. Figure 1A shows that the growth curves of mice were determined at indicated time points between the ages
-I-
WO 2006/074378 PCT/US2006/000474 of 5 and 40 weeks. Values are mean ± SE from 9-10 mice per group. *P < 0.05, **P < 0.01, AR~C versus male WT. Figure 1B shows the epididymal and perirenal fat pads isolated from 35-week-old mice (upper panel). Sections of WAT (white adipose tissue) are shown at 40x magnification (lower panel) of 35-week-old mice, scale bar, 200 pim. C: 5 Distribution of cell size of epididymal WATs from 35-week-old mice. 8. Figure 2 shows that AR~Y mice are insulin resistant, and glucose intolerant. Figure 2A shows the GTT (glucose tolerance test) (oral bolus 2 mg/g body weight) of 35 week-old mice after 14-h fast. Figure 2B shows the AUC analysis of GTT. Figure 2C shows the ITT (insulin tolerance test ) (intraperitoneal 1 U/kg body weight) of 25-week-old 10 mice. Figure 2D shows the ITT (intraperitoneal 1 U/kg body weight) of 35-week-old mice. Values are mean ± SE from 5-6 mice per group. *P < 0.05, **P <0.01, ***P <0.001, AR versus male WT. Figure 2E shows that in vivo P13K activity was measured in phosphotyrosine immunoprecipitates prepared from skeletal muscles, adipose tissues, and livers from 14-h fast of 35-week-old mice. Tissues were collected 3 min after 15 intraperitoneal injection of insulin or isotonic saline. The results were quantified by Phosphohmaging. Values are representative of 3 mice of each group. **P < 0.01, AR~ with insulin versus WT with insulin. Figure 2F shows the skeletal muscles and livers that were removed from 35-week-old, ad libitum-fed mice. Values of each group were converted into milligrams of TG (triglyceride) per gram of tissue (wet weight) after comparison with a 20 glycerol standard. Values are mean + SE from 5 mice per group. ***P < 0.001, ARC versus WT. 9. Figure 3 shows the Effects of AR deficiency on adipocyte-derived adipokine. Figure 3A shows the fed leptin concentrations in 8-, 25-, or 35-week-old mice. Figure 3B shows the relationship between fed leptin concentrations and body weight of 35-week-old 25 mice. Figure 3C shows the adiponectin concentrations in 35-week-old mice. Figure 3D shows the TNF-a concentrations in 35-week-old mice. Values are mean + SE from 5 mice per group. *P < 0.05, **P < 0.01, AR-Y versus WT; N.S., no significance. In D, n = 8 for WT mice and n =7 for AR- mice. Regression lines for both groups are shown. 10. Figure 4 shows that Aging AR4S mice developed leptin resistance but not 30 younger mice. Two groups of 35-week-old mice or 20-week-old mice received an intraperitoneal injection of either leptin (5 pg/g body weight) or isotonic saline. Figure 4A shows the food intake per 24-h of 35-week-old mice. Figure 4B shows the weight changes -2- WO 2006/074378 PCT/US2006/000474 per 24-h of 35-week-old mice. Figure 4C shows the food intake per 24-h of 20-week-old mice. Figure 4D shows the weight changes per 24-h of 20-week-old mice. Values are mean + SE from 3-4 mice per group. *P <0.05, WT with leptin versus control; tP < 0.05, leptin treatment versus control; ttP <0.001, leptin treatment versus control; N.S., no 5 significance. 11. Figure 5 shows the recombination of AR-loxP allele in the liver of ARM') mice, growth curve, cumulative weight gain, and serum glucose in WT and AR "'M mice on high fat diet (HFD). Mice were given HFD from 8 weeks as described in Methods. Figure 5(a) shows the detection of intact (wt) versus recombined (ko) allele and Slp by RT 10 PCR from liver. Figure 5(b) shows the body weight and (c) cumulative weight gain on HFD of the animals measured weekly. Also shown are fasting serum glucose levels (d) at 24 weeks, (e) at 36 weeks, and (f) at 52 weeks on HFD of the animals. 12.

The present compositions and methods may be understood more readily by reference to the following detailed description of preferred embodiments and the Examples included therein and to the Figures and their previous and following description. 16. Before the present compounds, compositions, articles, devices, and/or methods 5 are disclosed and described, it is to be understood that the compositions and methods are not limited to specific synthetic methods, specific recombinant biotechnology methods unless otherwise specified, or to particular reagents unless otherwise specified, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 10 17. It is estimated that by the year 2030 there will be approximately 366 million people affected by type 2 diabetes in worldwide (Wild,S, et al. (2004) Diabetes Care 27:1047-1053) with many of those affected in the elderly age group (Diabetes Care 21:296 309, 1998). Although the primary factors causing this disease are elusive, insulin resistance and leptin insensitivity may play a major role in its development (Saad, MF, et al. (1989) 15 Lancet 1:1356-1359). 18. Epidemiological evidence suggests that gender differences exist in the type 2 diabetes. The prevalence of type 2 diabetes is higher in men than women (Wild, S, et al. (2004) Diabetes Care 27:1047-1053), possibly due to the differences in insulin sensitivity and regional body fat deposition (Gale,EA, and Gillespie,KM. (2001) Diabetologia 44:3 20 15; Livingstone,C, and Collison,M. (2002) Clin.Sci.(Lond) 102:151-166). The detailed mechanisms of how sex hormones influence the insulin sensitivity or fat deposition, however, remain unclear. Testosterone and its metabolite, dihydrotestosterone (DHT), can activate androgen receptor (AR) to exert their androgenic actions. The proper or maximal androgen (A) action typically requires interaction with selective coregulators in selective 25 tissues (Chang,CS, et al. (1988) Science 240:324-326; Heinlein,CA, and Chang,C. (2002) Endocr.Rev. 23:175-200). 19. Leptin, the adipocyte-derived adipokine product of the ob gene, has been shown to induce a negative energy balance by reducing appetite and increasing energy expenditure (Friedman, JM, and Halaas,JL. (1998) Nature 395:763-770). Leptin circulates in serum at 30 levels that parallel the mass of body fat. However, obese individuals have been found to be resistant to the negative regulatory function of circulating leptin (Hamilton, BS, et al. (1995) Nat Med 1:953-956). The ob/ob and db/db mice that lack leptin or are leptin -4- WO 2006/074378 PCT/US2006/000474 resistant, respectively, are profoundly hyperphagic and hypometabolic, leading to an obese phenotype, and manifest numerous abnormalities, such as type 2 daibetes with severe insulin resistance, hypothermia and cold intolerance, infertility, and decrease in lean mass (Burks, DJ, et al. (2000) Nature 407:377-382; Chen, H, et al. (1996) Cell 84:491-495; 5 Chua, SCJ, et al. (1996) Science 271:994-996; Hausberg,M, et al. (2002) Diabetes 51:2434-2440; Lee,GH, et al. (1996) Nature 379:632-635). 20. Herein is described a conditional knockout strategy that was used to generate AR knockout mice (ARY) (Yeh,S, et al. (2002) Proc Natl Acad Sci U S A 99:13498 13503). Disclosed herein are the influences of loss of AR on insulin and leptin resistance, 10 and methods and compositons which arise from this connection of AR to the insulin and leptin resistance pathways. A. Definitions 21. As used in the specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, 15 for example, reference to "a pharmaceutical carrier" includes mixtures of two or more such carriers, and the like. 22. Ranges can be expressed herein as from "about" one particular value, and/or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when 20 values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as "about" 25 that particular value in addition to the value itself For example, if the value "10" is disclosed, then "about 10" is also disclosed. It is also understood that when a value is disclosed that "less than or equal to" the value, "greater than or equal to the value" and possible ranges between values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value "10" is disclosed the "less than or equal to 10"as 30 well as "greater than or equal to 10" is also disclosed. It is also understood that the throughout the application, data is provided in a number of different formats, and that this data, represents endpoints and starting points, and ranges for any combination of the data -5- WO 2006/074378 PCT/US2006/000474 points. For example, if a particular data point "10" and a particular data point 15 are disclosed, it is understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed as well as between 10 and 15. 23. In this specification and in the claims which follow, reference will be made to a 5 number of terms which shall be defined to have the following meanings: 24. "Optional" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. 25. "Primers" are a subset of probes which are capable of supporting some type of 10 enzymatic manipulation and which can hybridize with a target nucleic acid such that the enzymatic manipulation can occur. A primer can be made from any combination of nucleotides or nucleotide derivatives or analogs available in the art which do not interfere with the enzymatic manipulation. 26. "Probes" are molecules capable of interacting with a target nucleic acid, 15 typically in a sequence specific manner, for example through hybridization. The hybridization of nucleic acids is well understood in the art and discussed herein. Typically a probe can be made from any combination of nucleotides or nucleotide derivatives or analogs available in the art. 27. "Decrease" refers to lower or less than and typically in reference to a control or 20 other embodiment. For example, a level of a subject activity can be decreased either in reference to a control level of activity, the activity of a control performed in parallel with the subject activity, or the activity of a second subject activity. 28. "Increase" refers to higher or more than and typically in reference to a control or other embodiment. For example, a level of a subject activity can be increased either in 25 reference to a control level of activity, the activity of a control performed in parallel with the subject activity, or the activity of a second subject activity. 29. Throughout this application, various publications are referenced. The disclosures of these publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this 30 pertains. The references disclosed are also individually and specifically incorporated by reference herein for the material contained in them that is discussed in the sentence in which the reference is relied upon. -6- WO 2006/074378 PCT/US2006/000474 B. Compositions and Methods 1. Models for diabetes and heart disease 30. Androgen Receptor (AR) activity is shown herein to have a profound effect on leptin sensitivity (resistance), insulin resistance, glucose resistance, triglyceride levels, 5 high-density lipoprotein levels (HDL), and low-density lipoprotein (LDL) levels. Specifically, it is disclosed herein, that a decrease in AR activity results in increased insulin, glucose, and leptin resistance, increased HDL levels, increased uric acid, and decreased LDL levels. Thus, decreased AR activity can play a prime role in the development of Type IH diabetes as well as coronary heart disease. 10 31. It is shown herein that animals which lack functional AR, such as an AR knockout animal have leptin sensitivity (resistance), insulin resistance, glucose resistance, triglyceride levels, increased HDL, and decreased LDL levels. These animals are shown herein as a model or part of a model for Type H diabetes. 32. Disclosed are models for type II diabetes that comprise an animal which is an 15 AR knock out as well as models comprising an AR knock out animal and a particular assay, condition, or state, which is related to diabetes or heart disease, such as Type H diabetes, as well as animals that have a particular level of blood glucose as controlled, by for example, having been fed or fasted for a particular period of time. Thus, for example, disclosed are compositions as models for type II diabetes comprising an androgen receptor 20 knockout animal and an assay for type II diabetes. a) Androgen receptor knockouts 33. For example, an AR knock out animal is any animal with a disrupted AR loci or gene. Disclosed are methods of generating a cell line wherein the AR loci has been disrupted. For example, the AR loci can be disrupted by, for example, disrupting one of 25 the exons, such that a stop codon terminates translation of the AR peptide early or where the exon is completely taken out. The AR loci would include any exon or intron associated with the AR gene on the X chromosome. 34. The AR gene is considered any sequence associated with the AR locus. Thus, it would at least include the chromosomal nucleic acid contained within any organism that 30 expresses an AR, such as, the introns, exons, 5' upstream sequence involved with the AR -7- WO 2006/074378 PCT/US2006/000474 coding and non-coding sequence, and 3' downstream sequence involved with the AR coding and non coding sequence. 35. A disrupted AR loci can be any AR loci that does not produce a native AR protein. A disrupted AR loci would also include any AR loci wherein the nucleic acid of 5 the natural AR gene, including exons and introns has been altered. Typically the altering of the AR gene will cause a disruption in AR function, by for example, preventing DNA binding in the AR gene product or ligand binding in the AR gene product or transactivating activity in the AR gene product. The disrupted AR loci can be made using any known technique, including homologous recombination techniques. The disrupted loci can be an 10 alteration of any exon to produce a non-functional AR protein. Furthermore, disclosed are constructs and methods to mutate any exon in the AR through homologous recombination via the surrounding introns. 36. The AR knock outs can be produced so that they are conditional, by for example, being dependent on recombinase activity, such as Cre. For example, as disclosed 15 herein, the Cre-lox system has been successfully used herein to generate AR knockout mice (ARKO). This principle has been successfully applied for tissue-specific transgene expression (Orban PC, 1992), for site specific gene targeting (Gu, 1994) and for exchange of gene sequence by the "knock-in" method (Hank M, 1995). Thus, for example, the ARKO animal can have a liver-specific knock out by using the albumin promoter. It is 20 understood and herein contemplated that other ARKO animals can be used utilizing other tissue specific promoters known in the art. Disclosed herein, the system has been applied to avoid the infertility problem of male carriers of an ARKO. This strategy has been used to generate a knock-out model for those genes that are located in X or Y chromosomes and are critical in fertility. For example, exon 1 can be floxed through addition of a lox site in 25 sequence that will homologously recombine with Intron 1 and inron 2. Likewise lox sites could be inserted into sequence which would homologously recombine with intron 2 and intron 3 for exon 2, intron 3 and intron 4 for exon 3, intron 4 and intron 5 for exon 4, intron 5 and intron 6 for exon 5, and so forth for each exon which are considered disclosed herein. 30 37. The disrupted AR loci can be in any cell that contains an AR loci, such as an embryonic stem cell, an embryonic germ cell, a breast cell, a breast cancer cell, an ovary -8- WO 2006/074378 PCT/US2006/000474 cell, an ovary cancer cell, and any cell line of cells that contain AR genes which are expressed, such as prostate cells, testis, bone, brain, neural, and muscle. 38. The ARKOs can be in any cell or in any animal, such as a rat, mouse, non human primate (including but not limited to monkey and chimpanzee), rabbit, porcine, 5 ovine, or bovine. Thus, it is understood that the ARKO can be in any mammal. They can be used via any technique and the animals produced as well as their progeny are disclosed. 39. Disclosed are methods of making a model for type II diabetes comprising a) generating a mouse with an AR gene or necessary portion thereof for AR actvity, between two loxP sites, b) generating a mouse with Cre recombinase under the control of a p-actin 10 promoter (ACTB Cre+) and heterozygous for the AR gene, and c) mating a female ACTB Cre+ mouse with and ARloxP mouse creating an AR Cre-lox mouse. Although a Cre-loxP system is described herein to create the model, it is understood and herein contemplated that any inducible promoter system such as the Flp recombinase and the tetracycline inducible promoter system, may be used in place of the Cre-loxP inducible promoter 15 system. Also disclosed are methods of generating a model for type II diabetes comprising generating an androgen receptor knock out animal and assaying the animal for characteristics of type II diabetes. 40. Also disclosed are methods of making a model for Coronary Heart Disease (CHD) comprising a) generating a mouse with an AR gene or necessary portion thereof for 20 activity, between two loxP sites, b) generating a mouse with Cre recombinase under the control of a p-actin promoter (ACTB Cre+) and heterozygous for the AR gene, and c) mating a female ACTB Cre+ mouse with and ARloxP mouse creating an AR Cre-lox mouse. Also disclosed are methods of generating a model for Coronary Heart Disease (CHD) comprising generating an androgen receptor knock out animal and assaying the 25 animal for characteristics of coronary heart disease. b) Assays, conditions, or states related to diabetes 41. Often the models include an assay or a condition or a state that is related to diabetes which is either monitored or tested, for example. For example, a model could include the ARKO animal disclosed herein, along with a state the animal is put into, such 30 as a fed state or a fasting state for a period of time. It is understood and herein contemplated that periods of fasting can occur for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours prior to assay. It is also understood that -9- WO 2006/074378 PCT/US2006/000474 feeding can occur within 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours of the assay period. This can, for example, produce conditions which mimic a Type If diabetic situation. Thus, disclosed herein are models for Type II diabetes comprising an androgen receptor knockout animal and an assay for type H 5 diabetes, wherein the assay is performed on an animal that fasted for at least 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 hours or any number of hours in between. It is also understood that feeding can occur after a period of fasting. Thus, for example, the animal can be put into a fed state 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours prior to the assay period following 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 10 17, 18, 19, 20, 21, 22, 23, or 24 hours of fasting. In another model, the ARKO animal can have its blood glucose level tested or an insulin tolerance test (ITT) or glucose tolerance test (GTT) can be performed. Thus, for example, specifically disclosed are models for Type II diabetes comprising an androgen receptor knockout animal and an assay for type 11 diabetes, wherein the assay for Type H diabetes comprises an insulin tolerance test (ITT). 15 Also disclosed are models for Type 11 diabetes comprising an androgen receptor knockout animal and an assay for type IH diabetes, wherein the assay for Type H diabetes comprises a glucose tolerance test (GTT). In yet another model, the ARKO animal can have its leptin levels monitored or tested, or its triglyceride or HDL or LDL levels monitored or tested. Fatty acids, triglycerides, and cholesterol can also be measured. These and other tests can 20 be performed using, for example, and ELISA procedure. These tests can be performed as disclosed in the Examples or using any known method for testing same. For example, C reactive peptide (CRP), a marker for CHD, can be assayed by Elisa method. Adiponectin and Resistin, markers for Diabetes, also can be assayed by Elisa method. It is understood that these and other types of tests can also be performed on a subject to determine if they 25 have a particular disases condition, even if they are not an ARKO mouse, such as a human. 2. Use of the diabetes and CHD models 42. It is understood that the disclosed models can used in a variety of ways. For example, the models can be used to test the effect a particular composition, such as a potential drug for Type II diabetes, has on the knockout animal. The effect a composition 30 has on the model can be determined using one or more of the assays disclosed herein alone or in combination. The models can also be used to screen libraries of compounds to identify molecules having a particular effect on the model animal. Molecules having the -10- WO 2006/074378 PCT/US2006/000474 desired effect can be identified and further synthesized or tested for example. The models can also be used to test existing pharmaceuticals to see what their effect is the disclosed models. The information gained from performing tests on existing pharmaceuticals, for example, can be used to make treatment decisions regarding that particular composition or 5 one could make the decision to start other therapies in conjunction with that composition, if for example, the composition had a negative effect in the Type II diabetes model, one might look for a combination therapy for Type II diabetes or one might further choose to monitor diabetic indicators, such as glucose levels or insulin resistance, when taking that particular pharmaceutical. Thus herein disclosed are methods for screening drugs for an 10 effect on Type I1 Diabetes comprising administering the drug to an androgen deficient mouse and assaying for AR activity, wherein a increase in AR activity indicates a drug that can treat Type II Diabetes. It is understood that other characteristics of type II diabetes can also be measured, for example, the amount of leptin produced (Note: any other characteristic test of type II diabetes can be used and is herein contemplated). Thus, for 15 example, disclosed herein are are methods for screening drugs for an effect on Type II Diabetes comprising administering the drug to an androgen deficient mouse and assaying for AR activity, wherein a increase in AR activity indicates a drug that can treat Type H Diabetes, further comprising performing an assay for a characteristic of type H diabetes. It is also understood herein that a control may be used as a basis for assessing the effect of a 20 composition being screened. Thus, specifically contemplated herein are methods of testing a composition for its effect on Type H diabetes comprising administering the composition to an androgen receptor knockout animal, and performing an assay related to Type H diabetes, wherein a change in the assay relative to a control indicates the compound has an effect on Type II diabetes. Also disclosed are methods for screening drugs for an effect on 25 CHD comprising administering the drug to an Androgen deficient mouse and assaying for AR activity, wherein a increase in AR activity indicates a drug that can be used to treat CHD. 3. Methods of diagnosis and prognosis 43. The information that lack of androgen receptor leads to characteristics and 30 conditions related to diabetes, such as Type H diabetes, and CHD indicate that a variety of screening and testing methods are disclosed related to subjects and the presence of or likelihood to have or get diabetes, such as Type R diabetes, or CHD. -11- WO 2006/074378 PCT/US2006/000474 44. For example, subjects who have diabetes or Type II diabetes or CHD can have their AR activity tested. To test a human subject's AR activity, one could indirectly assay the serum levels of Testosterone or 5-alpha-dihydrotestosterone. Besides, one could assay the number of CAG repeats of AR in subject, which is inversely correlated with AR 5 activity. AR activity can also be performed using methods as described herein, for example, for assaying AR activity in tissue or cell samples from mice disclosed herein. An AR activity lower than that of a control would indicate that the diabetes or CHD of the subject could be due to the loss of AR activity. Steps could then be taken, as discussed herein, to elevate the activity of the AR activity to help alleviate or reduce the diabetes or 10 CHD. In another sitruation, a subject could have their AR activity tested. If their AR activity is low relative to a control, for example, then this could be a risk factor for acquiring diabetes or CHD in the future, such as a family history, is a risk factor. In this type of situation, the subject could, for example, begin life style changes or perform other types of preventative activities, if they were found to be at risk for diabetets or CHD based 15 on low AR activity. 45. Furthermore, the techniques and methods disclosed herein can be used to assess the likelihood a subject will develop a condition due to decreased AR activity. Thus, disclosed are methods for diagnosing the likelihood of a subject to develop Type II Diabetes comprising taking a tissue sample from the subject and assaying for AR activity, 20 wherein a decrease in AR activity indicates Type II Diabetes. It is understood that subjects with decreased AR activity can have increased leptin resistance and increased insulin resistance. Therefore, it is understood and herein contemplated that a subject with decreased AR activity will likely develop Type II diabetes. One measure of AR activity would be to assay the expression of AR dependent genes in the sample. Another measure 25 of AR acivity comprises assaying the amount of AR present in the sample. Similarly, the disclosed methods can be used to diagnose the likelihood a subject will develop coronary heart disease CHD. Thus also disclosed are methods for diagnosing the likelihood of a subject to develop CHD comprising taking a tissue sample from the subject and assaying for AR activity, wherein a decrease in AR activity indicates CHD. It is understood and 30 herein contemplated that subjects with decreased AR activity can have increased uric acid levels, increased HDL, and decreased LDL, all of which contribute to CHD. It is also understood that a subject can be a cell, mammal, mouse, or human. -12- WO 2006/074378 PCT/US2006/000474 46. The disclosed methods can also be used to diagnose a condition. Thus disclosed are methods of diagnosing a subject with Type II diabetes comprising a) obtaining a tissue sample, and b) assaying for AR activity, wherein a lack of AR indicates Type R diabetes. Also discosed a method of diagnosing a subject with CHD comprising a) 5 obtaining a tissue sample, and b) assaying for AR activity, wherein a lack of AR indicates CHD. It is understood that various tissue samples can be used with the disclosed methods. Specifically disclosed are methods, wherein the tissue sample is blood, white adipose tissue (WAT), liver tissue, or skeletal muscle. 47. It is also understood that the information disclosed herein indicates that 10 individuals receiving androgen ablation therapy should be monitored for diabetic or CHD types of conditions, and preventative efforts for each of these are indicated for those undergoing androgen ablation therapy or have androgen receptor deficiencies. Thus, a subset of subjects upon whom the types of assays and tests disclosed herein should be performed on, are those receiving androgen ablation therapy or have androgen receptor 15 deficiencies. Thus, also disclosed herein are methods of testing a subject for Type H diabetes comprising performing an assay for Type IE diabetes wherein the subject has an androgen receptor deficiency or has had androgen ablation therapy. 48. Androgen ablation thereapy is a commonly used method of treating cancer and in particular prostate cancer. However, as disclosed herein, the diminishment of AR 20 activity can have dramatic consequences in the patient. For example, the patient can develop leptin resistance and insulin resistance which are two of the main components of Type 11 Diabetes. Also, decreased AR activity can lead to increased high density lipoproteins, increased uric acid output, and decreased low-density lipoproteins associated with CHD. A patient being treated for cancer with an androgen ablatement regimin can 25 develope secondary problems associated with the treatment that left unchecked can put the patients life at risk. Therefore, a patient that developes Type II diabetes or CHD while under treatment with androgen ablatement therapy can be assessed to determine if AR is the reason for the developing Type II diabetes or CHD. If AR activity is decreased in the patient and tests indicate that diabetes or CHD is a problem, a new treatment can be 30 prescribed to avoid complications associated with Type II diabetes and CHD. Disclosed are methods for evaluating whether a treatment with a compound should be performed due to the effect the treatment has on Type R diabetes, wherein the compound modulates the -13- WO 2006/074378 PCT/US2006/000474 androgen activity, the method comprising a) exposing cells to the compound, and b) evaluating androgen activity in the presence of the compound, wherein a change in the androgen activity of the subject, relative to the androgen activity of a subject that has not been exposed to the compound, indicates that the compound modulates androgen activity, 5 and wherein a decrease in androgen activity indicates a negative effect on Type If Diabetes, providing an indication that treatment with the compound may not be indicated. 49. Also disclosed are methods for evaluating whether a treatment with a compound should be performed due to the effect the treatment has on CUD, wherein the compound modulates the androgen activity, the method comprising a) exposing a subject 10 to the compound, and b) evaluating androgen activity in the presence of the compound, wherein a change in the androgen activity of the subject, relative to the androgen activity of a subject that has not been exposed to the compound, indicates that the compound modulates androgen activity, and wherein a decrease in androgen activity indicates a negative effect on CHD, providing an indication that treatment with the compound may not 15 be indicated. 4. Treatments for diabetes and CHD 50. Due to the effects of AR activity on prinicipal activities (e.g., leptin resistance, insulin resistance, increased HDL) associated with Type II dabetes and CHD, agents that can increase AR activity can be used to treat these conditions, herein called AR activators. 20 AR activators can be any molecule discussed herein as increasing AR activity including coactivators and androgen receptor ligands and anlogs as discussed herein and understood. Thus disclosed are methods of administering an AR activator to a subject having diabetes, such as Type I or Type H, or CHD, or one or more of the symptoms or characteristics of these, such as those disclosed herein. Also disclosed are methods wherein the subject has 25 been diagnosed as having diabetes, such as Type I or Type II, or CHD, or one or more of the symptoms or characteristics of these, such as those disclosed herein. Furthermore disclosed are methods of treating diabetes, such as Type I or Type II, or CHD, or one or more of the symptoms or characteristics of these, such as those disclosed herein or decreasing or inhibiting diabetes, such as Type I or Type II, or CHD, or one or more of the 30 symptoms or characteristics of these, such as those disclosed herein. Also disclosed are -14- WO 2006/074378 PCT/US2006/000474 methods wherein the subject has been shown to have a reduced amount of AR activity. Also disclosed are methods wherein the subject has been shown to have reduced levels of testosterone or one of its precursors or metabolites or molecules in the testosterone synthesis pathway as disclosed herein. A reduced level can be determined by either 5 comparing the amount of the testosterone or one of its precursors or metabolites or molecules in the testosterone synthesis pathway in a subject and comparing it to the amount that had been present in the subject at a prior determination of the same. A reduced level can also include a comparison of the level of testosterone or one of its precursors or metabolites or molecules in the testosterone synthesis pathway in a subject to 10 a known standard or average amount for the same. For example, average levels of testosterone for males can be 300-1,000ng/dl or 300-1,100ng/dl. Average testosterone levels in women can be about 10 times lower, such as between 15-70 ng/DL for women aged 20-39 and between 4-70 ng/dL for women aged 40-59. 51. Disclosed are methods of treating a subject with Type II Diabetes comprising 15 administering to the subject an agent that modulates AR activity, wherein an increase in AR activity reduces Type H Diabetes. Also disclosed are methods of treating a subject with CHD comprising administering to the subject an agent that modulates AR activity, wherein an increase in AR activity reduces CHD. It is understood that agent for treating CHD or Type I diabetes can include hormones such as testosterone and DHT. Thus, 20 dpecifically disclosed are methods of treating a subject with Type 11 diabetes or CHD, wherein the agent comprises testosterone or CHD. There are number of compositions which act as AR coactivators/coregulators including ARA24, ARA54, ARA55, ARA70, ARA267, gelsolin, and supervillian. A discussion of these co-regulators can be found in United States Patent Application Nos. 60/387,087 filed on June 6, 2003, 60/093,239 filed 25 on July 17, 1998, 60/100,243 filed on September 14, 1998, and 09/354,221, filed on July 15, 1999, as well as PCT application no. PCT/US03/17937, all of which are herein incorporated by reference at least for material related to co-activators or modulators of AR. a) AR domains 52. Compared to the quite conserved DBD and LBD, the N-terminus is quite 30 polymorphic in terms of sequence and length between NRs. The N-terminus is more likely to provide unique surfaces to recruit distinct factors that contribute to the specific action of -15- WO 2006/074378 PCT/US2006/000474 a certain NR. The AR has a large N-termius (ARN) and there are two distinct regions important for its transactivation function residing within the ARN: residues 141-338, which are required for full ligand-inducible transactivation, and residues 360-494, where the ligand-independent activation function-1 (AF-1) region is located (Heinlein, C.A., et al. 5 2002. Endocr. Rev. 23:175-200). Coactivators and corepressors have been identified to interact with ARN (Hsiao, P., et al. 1999. J Bio. Chem. 274:22373-22379, Hsiao, P., et al. 1999. J. Biol. Chem. 274:20229-20234, Knudsen, K.E., et al. 1999. Cancer Res. 59:2297 2301, Lee, D.K., et al. 2000. J. Biol. Chem. 275:9308-9313, Markus, S.M., et al. 2002. Mol. Biol. Cell 13:670-682, Petre, C.E., et al. 2002. J. Bio. Chem. 277:2207-2215). 10 Furthermore, although ARN extends to more than one half of the full length protein, its associated proteins are relatively fewer compared to those associated with AR DBD and AR LBD, presumably due to the existence of the AF-1 region which limits the application of conventional yeast-two hybrid system by using ARN as bait. It's likely there are still more ARN associated proteins remaining to be identified. 15 53. AR is classified with glucocorticoid receptor (GR), mineralocorticoid receptor and progesterone receptor (PR) as one group within the nuclear receptor (NR) superfamily, since they share high homology in the DBD and recognize very similar hormone response elements (Forman, B.M. et al. 1990. Mol. Endocrinol. 4:1293-1301, Laudet, V., et al. 1992. EMBO J. 11:1003-1013). However, the physiological responses mediated by these 20 receptors upon cognate ligand activation are quite distinct and hormone specific. Apparently, these cannot be explained by a specific DNA-binding through the DBD. Factors located outside the DBD may play a key role in determining the specific hormone responses. b) Androgen receptor signalling 25 54. Androgen exerts its effects via the intracellular AR, a member of the superfamily of nuclear receptors (Chang, C. S., et al. (1988) Science 240 (4850), 324-6, Mangelsdorf, D. J., et al. (1995) Cell 83 (6), 835-9). Upon androgen binding, AR dissociates from the heat-shock proteins and binds to androgen response elements, resulting in upregulation or downregulation of the transcription of AR target genes. In 30 addition to responding to ligands, the AR is affected by kinase signaling pathways which directly or indirectly alter the biological response to androgens. This phenomenon is mediated by the AR, as antiandrogens have been shown to block kinase-induced -16- WO 2006/074378 PCT/US2006/000474 transcriptional activation (Sadar, M. D. (1999) JBiol Chen 274 (12), 7777-83). Growth factors, cytokines, and neuropeptides have been implicated in various in vitro and in vivo models of human malignancies, including prostate cancers (Burfeind, P., et al. (1996) Proc Nat! Acad Sci US A 93 (14), 7263-8). In the absence of androgens, insulin-like growth 5 factor-1 (IGF-1), keratinocyte growth factor (KGF), and epidermal growth factor (EGF) are able to activate transcription of androgen receptor-regulated genes in prostate cancer cells (Culig, Z., et al. (1995) Eur Urol 27 (Suppl 2), 45-7). MAPK and Akt kinase cascades have been shown to be involved in growth factor-mediated AR activation (Yeh, S., et al. (1999) Proc Natl Acad Sci USA 96 (10), 5458-63, Wen, Y., et al. (2000) Cancer Res 60 (24), 10 6841-5, Lin, H. K., et al. (2001) Proc NatLA cad Sci U SA 98 (13), 7200-5). c) Androgen Receptor ligands and derivatives 55. AR can be activated and have increased activity, such as transcription activity, as described herein, when AR is bound to its ligand or an activating derivative of said ligand, a precursor to said ligand, a metabolite of said ligand, or a composition that 15 increases a protein or small molecule in the pathway that produces testosterone or an androgen receptor ligand. AR is activated by androgens such as testosterone and 5-a dihydrotestosterone. 56. Principal mammalian androgens are testosterone and 5-a-dihydrotestosterone. There are variety of classes of androgens including Delta-3,4-3-keto androgens, which 20 included Delta-4-androstenedione (Adione), Testosterone, and 1 1-Beta-hydroxy androstenedione (11-Adione); Delta-5,6-3-keto androgens, which include, Dehydroepiandrosterone, also known as dehydroisoandrosterone (DHEA), DHEA sulfate (DHEAS); and Delta-5-androstenedion; 5-Alpha-reduced androgens, which include, 5 Alpha-dihydrotestosterone (dihydrotestosterone, DHT) and 5-Alpha-androstanediol; 17 25 Keto-steroids, which include DHEA, DHEAS, Delta-4-androstenedione (Adione), Delta-5 androstenedione, and 1 1-Beta-hydroxy-androstenedione (11-Adione). 57. Other analogs of testosterone can be found in Solo et al., "Ring-D-bridged steroid analogs. 8. Testosterone analogs," J Med Chem. 1970 Jul;13(4):751-4. which is herein incorporated by reference in its entirety and at least material related to testosterone 30 analogs. 58. The structure of testosterone contains a 17-f-OH (hydroxyl) and a 3-keto group which are necessary for activity. Oxidation of the 17-fl-OH to a 17-keto group, or -17- WO 2006/074378 PCT/US2006/000474 conversion to a 17 o'-OH, results in steroids with decreased androgen activity. Likewise, the 3-OH instead of 3-keto group is much less active partly due to increased metabolism. (http://www.neurosci.pharm.utoledo.edu/MBC3320/androgens.htm, Dr. William S. Messer, Jr, This page was last updated on Wedneday, April 19, 2000 at 5:23 p.m.) Testwterone 5 59. Typically testosterone analogs increase oral activity, prolonged action, and/or selectivity for either anabolic or androgenic activity, but not both. Various testosterone 10 analogs and testosterone and other androgen activators can be administered as a topical cream. (http://www.neurosci.pbarm.utoledo.edu/MBC3320/androgens.htm, Dr. William S. Messer, Jr, This page was last updated on Wedneday, April 19, 2000 at 5:23p.m.) 60. Testosterone analogs show increased activity if Reducing the double bond between carbons 4 and 5 (A4) increases testosterone analog activity. This reduction can be 15 catalyzed by the action of 5-c reductase. Introduction of a fluorine at C9, as for glucocorticoids, increases activity. Furthermore, addition of an alkyl group to position 17 increases stability by preventing oxidation to an inactive 17-keto form. Oxidation to the 17 keto form typically occurs in the liver and can be an obstacle to oral administration. The 17-a methyl testosterone has twice the activity of native testosterone and can enter through 20 the buccal mucosa (mouth membranes). Loss of the 19-CH 3 enhances selectivity for anabolic activity by decreasing seletively the androgenic effect. (http://www.neurosci.pharm.utoledo.edu/MBC3320/androgens.htm, Dr. William S.

Other testosterone analogs which can b used herein as AR activators can be found in United States Patent No. 6,828,313 for "Use of oxandrolone in the treatment of 10 burns and other wounds" issued December 7, 2004 to d. Fishbein, which is herein incorporated by reference in its entirety and at least for material related to testosterone analogs as discussed herein. 5. Antibodies 67. There are avariety of antibodies that are disclosed herein, in particular 15 antibodies that bind AR in any of its various forms, sujch as logand bound, as well as binding of coactivators-or co-regulators of AR. Also disclosed are antibodies that bind proteins whose production is regulated by AR. The disclosed antibodies can be used in assays for determining the presence of AR either directly or indirectly and thus, can be used to assay for AR activity either directly or indirectly. Also disclosed are antibodies which 20 are capable of increasing the AR activity, or binding other ligands, such that the diabetic related effects disclosed herein, are reduced. a) Antibodies Generally 68. The term "antibodies" is used herein in a broad sense and includes both polyclonal and monoclonal antibodies. In addition to intact immunoglobulin molecules, 25 also included in the term "antibodies" are fragments or polymers of those immunoglobulin molecules, and human or humanized versions of immunoglobulin molecules or fragments thereof, as described herein. The antibodies are tested for their desired activity using the in vitro assays described herein, or by analogous methods, after which their in vivo -20- WO 2006/074378 PCT/US2006/000474 therapeutic and/or prophylactic activities are tested according to known clinical testing methods. 69. The term "monoclonal antibody" as used herein refers to an antibody obtained from a substantially homogeneous population of antibodies, i.e., the individual antibodies 5 within the population are identical except for possible naturally occurring mutations that may be present in a small subset of the antibody molecules. The monoclonal antibodies herein specifically include "chimeric" antibodies in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, 10 while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, as long as they exhibit the desired antagonistic activity (See, U.S. Pat. No. 4,816,567 and Morrison et al., Proc. Nati. Acad. Sci. USA, 81:6851-6855 (1984)). 15 70. Monoclonal antibodies of the invention can be prepared using hybridoma methods, such as those described by Kohler and Milstein, Nature, 256:495 (1975). In a hybridoma method, a mouse or other appropriate host animal is typically immunized with an immunizing agent to elicit lymphocytes that produce or are capable of producing antibodies that will specifically bind to the immunizing agent. Alternatively, the 20 lymphocytes may be immunized in vitro, e.g., using the HIV Env-CD4-co-receptor complexes described herein. 71. The monoclonal antibodies may also be made by recombinant DNA methods, such as those described in U.S. Pat. No. 4,816,567 (Cabilly et al.). DNA encoding the monoclonal antibodies of the invention can be readily isolated and sequenced using 25 conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of murine antibodies). Libraries of antibodies or active antibody fragments can also be generated and screened using phage display techniques, e.g., as described in U.S. Patent No. 5,804,440 to Burton et al. and U.S. Patent No. 6,096,441 to Barbas et al. 30 72. In vitro methods are also suitable for preparing monovalent antibodies. Digestion of antibodies to produce fragments thereof, particularly, Fab fragments, can be accomplished using routine techniques known in the art. For instance, digestion can be -21- WO 2006/074378 PCT/US2006/000474 performed using papain. Examples of papain digestion are described in WO 94/29348 published Dec. 22, 1994 and U.S. Pat. No. 4,342,566. Papain digestion of antibodies typically produces two identical antigen binding fragments, called Fab fragments, each with a single antigen binding site, and a residual Fc fragment. Pepsin treatment yields a 5 fragment that has two antigen combining sites and is still capable of cross-linking antigen. 73. The fragments, whether attached to other sequences or not, can also include insertions, deletions, substitutions, or other selected modifications of particular regions or specific amino acids residues, provided the activity of the antibody or antibody fragment is not significantly altered or impaired compared to the non-modified antibody or antibody 10 fragment. These modifications can provide for some additional property, such as to remove/add amino acids capable of disulfide bonding, to increase its bio-longevity, to alter its secretory characteristics, etc. In any case, the antibody or antibody fragment must possess a bioactive property, such as specific binding to its cognate antigen. Functional or active regions of the antibody or antibody fragment may be identified by mutagenesis of a 15 specific region of the protein, followed by expression and testing of the expressed polypeptide. Such methods are readily apparent to a skilled practitioner in the art and can include site-specific mutagenesis of the nucleic acid encoding the antibody or antibody fragment. (Zoller, M.J. Curr. Opin. Biotechnol. 3:348-354, 1992). 74. As used herein, the term "antibody" or "antibodies" can also refer to a human 20 antibody and/or a humanized antibody. Many non-human antibodies (e.g., those derived from mice, rats, or rabbits) are naturally antigenic in humans, and thus can give rise to undesirable immune responses when administered to humans. Therefore, the use of human or humanized antibodies in -the methods of the invention serves to lessen the chance that an antibody administered to a human will evoke an undesirable immune response. 25 b) Human antibodies 75. The human antibodies of the invention can be prepared using any technique. Examples of techniques for human monoclonal antibody production include those described by Cole et al. (Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, p. 77, 1985) and by Boemer et al. (J. Immunol., 147 (1):86-95, 1991). Human antibodies of the 30 invention (and fragments thereof) can also be produced using phage display libraries (Hoogenboom et al., J. Mol. Biol., 227:381, 1991; Marks et al., J. Mol. Biol., 222:581, 1991). -22- WO 2006/074378 PCT/US2006/000474 76. The human antibodies of the invention can also be obtained from transgenic animals. For example, transgenic, mutant mice that are capable of producing a full repertoire of human antibodies, in response to immunization, have been described (see, e.g., Jakobovits et al., Proc. Nati. Acad. Sci. USA, 90:2551-255 (1993); Jakobovits et al., 5 Nature, 362:255-258 (1993); Bruggermann et al., Year in Immunol., 7:33 (1993)). Specifically, the homozygous deletion of the antibody heavy chain joining region (J (H)) gene in these chimeric and germ-line mutant mice results in complete inhibition of endogenous antibody production, and the successful transfer of the human germ-line antibody gene array into such germ-line mutant mice results in the production of human 10 antibodies upon antigen challenge. Antibodies having the desired activity are selected using Env-CD4-co-receptor complexes as described herein. c) Humanized antibodies 77. Optionally, the antibodies are generated in other species and "humanized" for administration in humans. Humanized forms of non-human (e.g., murine) antibodies are 15 chimeric immunoglobulins, immunoglobulin chains or fragments thereof (such as scFv, sFv, Fv, Fab, Fab', F (ab')2, or other antigen-binding subsequences of antibodies) which contain minimal sequence derived from non-human immunoglobulin. Humanized antibodies include human immunoglobulins (recipient antibody) in which residues from a complementary determining region (CDR) of the recipient are replaced by residues from a 20 CDR of a non-human species (donor antibody) such as mouse, ret or rabbit having the desired specificity, affinity and capacity. In some instances, Fv framework residues of the human immunoglobulin are replaced by corresponding non-human residues. Humanized antibodies may also comprise residues that are found neither in the recipient antibody nor in the imported CDR or framework sequences. In general, the humanized antibody will 25 comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the CDR regions correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin consensus sequence. The humanized antibody optimally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a 30 human immunoglobulin (Jones et al., Nature, 321:522-525 (1986); Riechmann et al., Nature, 332:323-327 (1988); and Presta, Curr. Op. Struct. Biol., 2:593-596 (1992)). -23- WO 2006/074378 PCT/US2006/000474 78. Methods for humanizing non-human antibodies are well known in the art. Generally, a humanized antibody has one or more amino acid residues introduced into it from a source that is non-human. These non-human amino acid residues are often referred to as "import" residues, which are typically taken from an "import" variable domain. 5 Humanization can be essentially performed following the method of Winter and co workers (Jones et al., Nature, 321:522-525 (1986); Riechmann et al., Nature, 332:323-327 (1988); Verhoeyen et al., Science, 239:1534-1536 (1988)), by substituting rodent CDRs or CDR sequences for the corresponding sequences of a human antibody. Accordingly, such "humanized" antibodies are chimeric antibodies (U.S. Pat. No. 4,816,567), wherein 10 substantially less than an intact human variable domain has been substituted by the corresponding sequence from a non-human species. In practice, humanized antibodies are typically human antibodies in which some CDR residues and possibly some FR residues are substituted by residues from analogous sites in rodent antibodies. 79. The choice of human variable domains, both light and heavy, to be used in 15 making the humanized antibodies is very important in order to reduce antigenicity. According to the "best-fit" method, the sequence of the variable domain of a rodent antibody is screened against the entire library of known human variable domain sequences. The human sequence which is closest to that of the rodent is then accepted as the human framework (FR) for the humanized antibody (Sims et al., J. Immunol., 151:2296 (1993) 20 and Chothia et al., J. Mol. Biol., 196:901 (1987)). Another method uses a particular framework derived from the consensus sequence of all human antibodies of a particular subgroup of light or heavy chains. The same framework may be used for several different humanized antibodies (Carter et al., Proc. Natl. Acad. Sci. USA, 89:4285 (1992); Presta et al., J. Immunol., 151:2623 (1993)). 25 80. It is further important that antibodies be humanized with retention of high affinity for the antigen and other favorable biological properties. To achieve this goal, according to a preferred method, humanized antibodies are prepared by a process of analysis of the parental sequences and various conceptual humanized products using three dimensional models of the parental and humanized sequences. Three dimensional 30 immunoglobulin models are commonly available and are familiar to those skilled in the art. Computer programs are available which illustrate and display probable three-dimensional conformational structures of selected candidate immunoglobulin sequences. Inspection of -24- WO 2006/074378 PCT/US2006/000474 these displays permits analysis of the likely role of the residues in the functioning of the candidate immunoglobulin sequence, i.e., the analysis of residues that influence the ability of the candidate immunoglobulin to bind its antigen. In this way, FR residues can be selected and combined from the consensus and import sequence so that the desired 5 antibody characteristic, such as increased affinity for the target antigen (s), is achieved. In general, the CDR residues are directly and most substantially involved in influencing antigen binding (see, WO 94/04679, published 3 March 1994). d) Monoclonal Antibodies 81. The term "monoclonal antibody" as used herein refers to an antibody obtained 10 from a substantially homogeneous population of antibodies, i.e., the individual antibodies within the population are identical except for possible naturally occurring mutations that may be present in a small subset of the antibody molecules. The monoclonal antibodies herein specifically include "chimeric" antibodies in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies 15 derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain (s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, as long as they exhibit the desired antagonistic activity (See, U.S. Pat. No. 4,816,567 and Morrison et al., Proc. Nati. 20 Acad. Sci. U.S.A., 81:6851-6855 (1984)). 82. Monoclonal antibodies of the invention can be prepared using hybridoma methods, such as those described by Kohler and Milstein, Nature, 256:495 (1975). In a hybridoma method, a mouse or other appropriate host animal is typically immunized with an immunizing agent to elicit lymphocytes that produce or are capable of producing 25 antibodies that will specifically bind to the immunizing agent. Alternatively, the lymphocytes may be immunized in vitro, e.g., using the complexes described herein. 83. Transgenic animals (e.g., mice) that are capable, upon immunization, of producing a full repertoire of human antibodies in the absence of endogenous immunoglobulin production can be employed. For example, it has been described that the 30 homozygous deletion of the antibody heavy chain joining region (J (H)) gene in chimeric and germ-line mutant mice results in complete inhibition of endogenous antibody production. Transfer of the human germ-line immunoglobulin gene array in such germ -25- WO 2006/074378 PCT/US2006/000474 line mutant mice will result in the production of human antibodies upon antigen challenge (see, e.g., Jakobovits et al., Proc. Natl. Acad. Sci. USA, 90:2551-255 (1993); Jakobovits et al., Nature, 362:255-258 (1993); Bruggemann et al., Year in Immuno., 7:33 (1993)). Human antibodies can also be produced in phage display libraries (Hoogenboom et al., J. 5 Mol. Biol., 227:381 (1991); Marks et al., J. Mol. Biol., 222:581 (1991)). The techniques of Cote et al. and Boerner et al. are also available for the preparation of human monoclonal antibodies (Cole et al., Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, p.'77 (1985); Boerner et al., J. Immunol., 147 (1):86-95 (1991)). 84. Generally, either peripheral blood lymphocytes ("PBLs") are used in methods of 10 producing monoclonal antibodies if cells of human origin are desired, or spleen cells or lymph node cells are used if non-human mammalian sources are desired. The lymphocytes are then fused with an immortalized cell line using a suitable fusing agent, such as polyethylene glycol, to form a hybridoma cell (Goding, "Monoclonal Antibodies: Principles and Practice" Academic Press, (1986) pp. 59-103). Immortalized cell lines are 15 usually transformed mammalian cells, including myeloma cells of rodent, bovine, equine, and human origin. Usually, rat or mouse myeloma cell lines are employed. The hybridoma cells may be cultured in a suitable culture medium that preferably contains one or more substances that inhibit the growth or survival of the unfused, immortalized cells. For example, if the parental cells lack the enzyme hypoxanthine guanine phosphoribosyl 20 transferase (HGPRT or HPRT), the culture medium for the hybridomas typically will include hypoxanthine, aminopterin, and thymidine ("HAT medium"), which substances prevent the growth of HGPRT-deficient cells. Preferred immortalized cell lines are those that fuse efficiently, support stable high level expression of antibody by the selected antibody-producing cells, and are sensitive to a medium such as HAT medium. More 25 preferred immortalized cell lines are murine myeloma lines, which can be obtained, for instance, from the Salk Institute Cell Distribution Center, San Diego, Calif. and the American Type Culture Collection, Rockville, Md. Human myeloma and mouse-human heteromyeloma cell lines also have been described for the production of human monoclonal antibodies (Kozbor, J. Immunol., 133:3001 (1984); Brodeur et al., 30 "Monoclonal Antibody Production Techniques and Applications" Marcel Dekker, Inc., New York, (1987) pp. 51-63). The culture medium in which the hybridoma cells are cultured can then be assayed for the presence of monoclonal antibodies directed against -26- WO 2006/074378 PCT/US2006/000474 ARA67, AR, GSK2B, or hRad9, for example. Preferably, the binding specificity of monoclonal antibodies produced by the hybridoma cells is determined by immunoprecipitation or by an in vitro binding assay, such as radioimmunoassay (RIA) or enzyme-linked immunoabsorbent assay (ELISA). Such techniques and assays are known in 5 the art, and are described further in the Examples below or in Harlow and Lane "Antibodies, A Laboratory Manual" Cold Spring Harbor Publications, New York, (1988). 85. After the desired hybridoma cells are identified, the clones may be subcloned by limiting dilution or FACS sorting procedures and grown by standard methods. Suitable culture media for this purpose include, for example, Dulbecco's Modified Eagle's Medium 10 and RPMI-1640 medium. Alternatively, the hybridoma cells may be grown in vivo as ascites in a mammal. 86. The monoclonal antibodies secreted by the subclones may be isolated or purified from the culture medium or ascites fluid by conventional immunoglobulin purification procedures such as, for example, protein A-Sepharose, protein G, 15 hydroxylapatite chromatography, gel electrophoresis, dialysis, or affinity chromatography. 87. The monoclonal antibodies may also be made by recombinant DNA methods, such as those described in U.S. Pat. No. 4,816,567 (Cabilly et al.). DNA encoding the monoclonal antibodies of the invention can be readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding 20 specifically to genes encoding the heavy and light chains of murine antibodies). Libraries of antibodies or active antibody fragments can also be generated and screened using phage display techniques, e.g., as described in U.S. Patent No. 5,804,440 to Burton et al. and U.S. Patent No. 6,096,441 to Barbas et al. 88. In vitro methods are also suitable for preparing monovalent antibodies. 25 Digestion of antibodies to produce fragments thereof, particularly, Fab fragments, can be accomplished using routine techniques known in the art. For instance, digestion can be performed using papain. Examples of papain digestion are described in WO 94/29348 published Dec. 22, 1994 and U.S. Pat. No. 4,342,566. Papain digestion of antibodies typically produces two identical antigen binding fragments, called Fab fragments, each 30 with a single antigen binding site, and a residual Fc fragment. Pepsin treatment yields a fragment that has two antigen combining sites and is still capable of cross-linking antigen. e) Antibody fragments -27- WO 2006/074378 PCT/US2006/000474 89. Also disclosed are fragments of antibodies which have bioactivity. The polypeptide fragments of the present invention can be recombinant proteins obtained by cloning nucleic acids encoding the polypeptide in an expression system capable of producing the polypeptide fragments thereof, such as an adenovirus or baculovirus 5 expression system. For example, one can determine the active domain of an antibody from a specific hybridoma that can cause a biological effect associated with the interaction of the antibody with ARA67, AR, GSK2B, hRad9, TR2, or TR4, for example. For example, amino acids found to not contribute to either the activity or the binding specificity or affinity of the antibody can be deleted without a loss in the respective activity. For 10 example, in various embodiments, amino or carboxy-terminal amino acids are sequentially removed from either the native or the modified non-immunoglobulin molecule or the immunoglobulin molecule and the respective activity assayed in one of many available assays. In another example, a fragment of an antibody comprises a modified antibody wherein at least one amino acid has been substituted for the naturally occurring amino acid 15 at a specific position, and a portion of either amino terminal or carboxy terminal amino acids, or even an internal region of the antibody, has been replaced with a polypeptide fragment or other moiety, such as biotin, which can facilitate in the purification of the modified antibody. For example, a modified antibody can be fused to a maltose binding protein, through either peptide chemistry or cloning the respective nucleic acids encoding 20 the two polypeptide fragments into an expression vector such that the expression of the coding region results in a hybrid polypeptide. The hybrid polypeptide can be affinity purified by passing it over an amylose affinity column, and the modified antibody receptor can then be separated from the maltose binding region by cleaving the hybrid polypeptide with the specific protease factor Xa. (See, for example, New England Biolabs Product 25 Catalog, 1996, pg. 164.). Similar purification procedures are available for isolating hybrid proteins from eukaryotic cells as well. 90. The fragments, whether attached to other sequences or not, include insertions, deletions, substitutions, or other selected modifications of particular regions or specific amino acids residues, provided the activity of the fragment is not significantly altered or 30 impaired compared to the nonmodified antibody or antibody fragment. These modifications can provide for some additional property, such as to remove or add amino acids capable of disulfide bonding, to increase its bio-longevity, to alter its secretory -28- WO 2006/074378 PCT/US2006/000474 characteristics, etc. In any case, the fragment must possess a bioactive property, such as binding activity, regulation of binding at the binding domain, etc. Functional or active regions of the antibody may be identified by mutagenesis of a specific region of the protein, followed by expression and testing of the expressed polypeptide. Such methods are readily 5 apparent to a skilled practitioner in the art and can include site-specific mutagenesis of the nucleic acid encoding the antigen. (Zoller MJ et al. Nucl. Acids Res. 10:6487-500 (1982). 91. A variety of immunoassay formats may be used to select antibodies that selectively bind with a particular protein, variant, or fragment. For example, solid-phase ELISA immunoassays are routinely used to select antibodies selectively immunoreactive 10 with a protein, protein variant, or fragment thereof. See Harlow and Lane. Antibodies, A Laboratory Manual. Cold Spring Harbor Publications, New York, (1988), for a description of immunoassay formats and conditions that could be used to determine selective binding. The binding affinity of a monoclonal antibody can, for example, be determined by the Scatchard analysis of Munson et al., Anal. Biochem., 107:220 (1980). 15 f) Administration of antibodies 92. Antibodies of the invention are preferably administered to a subject in a pharmaceutically acceptable carrier. Suitable carriers and their formulations are described in Remington: The Science and Practice of Pharmacy (19th ed.) ed. A.R. Gennaro, Mack Publishing Company, Easton, PA 1995. Typically, an appropriate amount of a 20 pharmaceutically-acceptable salt is used in the formulation to render the formulation isotonic. Examples of the pharmaceutically-acceptable carrier include, but are not limited to, saline, Ringer's solution and dextrose solution. The pH of the solution is preferably from about 5 to about 8, and more preferably from about 7 to about 7.5. Further carriers include sustained release preparations such as semipermeable matrices of solid 25 hydrophobic polymers containing the antibody, which matrices are in the form of shaped articles, e.g., films, liposomes or microparticles. It will be apparent to those persons skilled in the art that certain carriers may be more preferable depending upon, for instance, the route of administration and concentration of antibody being administered. 93. The antibodies can be administered to the subject, patient, or cell by injection 30 (e.g., intravenous, intraperitoneal, subcutaneous, intramuscular), or by other methods such as infusion that ensure its delivery to the bloodstream in an effective form. Local or intravenous injection is preferred. -29- WO 2006/074378 PCT/US2006/000474 94. Effective dosages and schedules for administering the antibodies may be determined empirically, and making such determinations is within the skill in the art. Those skilled in the art will understand that the dosage of antibodies that must be administered will vary depending on, for example, the subject that will receive the 5 antibody, the route of administration, the particular type of antibody used and other drugs being administered. Guidance in selecting appropriate doses for antibodies is found in the literature on therapeutic uses of antibodies, e.g., Handbook of Monoclonal Antibodies, Ferrone et al., eds., Noges Publications, Park Ridge, N.J., (1985) ch. 22 and pp. 303-357; Smith et al., Antibodies in Human Diagnosis and Therapy, Haber et al., eds., Raven Press, 10 New York (1977) pp. 365-389. A typical daily dosage of the antibody used alone might range from about 1 pg/kg to up to 100 mg/kg of body weight or more per day, depending on the factors mentioned above. g) Nucleic acid approaches for antibody delivery 95. The AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, 15 and SRC-1 antibodies and antibody fragments, for example, can also be administered-to patients or subjects as a nucleic acid preparation (e.g., DNA or RNA) that encodes the antibody or antibody fragment, such that the patient's or subject's own cells take up the nucleic acid and produce and secrete the encoded antibody or antibody fragment. 6. Compositions identified by screening with disclosed compositions / 20 combinatorial chemistry a) Combinatorial chemistry 96. The disclosed compositions can be used as targets for any combinatorial technique to identify molecules or macromolecular molecules that interact with the disclosed compositions in a desired way. Particular disclosed are assays for identifying 25 molecules that modulate AR or another ligand, such that the diabetic related effects of a loss of AR as disclosed herein are reduced or decreased. 97. It is understood that when using the disclosed compositions in combinatorial techniques or screening methods, molecules, such as macromolecular molecules, will be identified that have particular desired properties such as inhibition or stimulation of the 30 target molecule's function. The molecules identified and isolated when using the disclosed compositions, such as, AR, RB, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1, are also disclosed. Thus, the products produced using the -30- WO 2006/074378 PCT/US2006/000474 combinatorial or screening approaches that involve the disclosed compositions, such as, AR, RB, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1, are also considered herein disclosed. 98. Combinatorial chemistry includes but is not limited to all methods for isolating 5 small molecules or macromolecules that are capable of binding either a small molecule or another macromolecule, typically in an iterative process. Proteins, oligonucleotides, and sugars are examples of macromolecules. For example, oligonucleotide molecules with a given function, catalytic or ligand-binding, can be isolated from a complex mixture of random oligonucleotides in what has been referred to as "in vitro genetics" (Szostak, TIBS 10 19:89, 1992). One synthesizes a large pool of molecules bearing random and defined sequences and subjects that complex mixture, for example, approximately 1015 individual sequences in 100 pLg of a 100 nucleotide RNA, to some selection and enrichment process. Through repeated cycles of affinity chromatography and PCR amplification of the molecules bound to the ligand on the column, Ellington and Szostak (1990) estimated that 15 1 in 1010 RNA molecules folded in such a way as to bind a small molecule dyes. DNA molecules with such ligand-binding behavior have been isolated as well (Ellington and Szostak, 1992; Bock et al, 1992). Techniques aimed at similar goals exist for small organic molecules, proteins, antibodies and other macromolecules known to those of skill in the art. Screening sets of molecules for a desired activity whether based on small 20 organic libraries, oligonucleotides, or antibodies is broadly referred to as combinatorial chemistry. Combinatorial techniques are particularly suited for defining binding interactions between molecules and for isolating molecules that have a specific binding activity, often called aptamers when the macromolecules are nucleic acids. 99. There are a number of methods for isolating proteins which either have de novo 25 activity or a modified activity. For example, phage display libraries have been used to isolate numerous peptides that interact with a specific target. (See for example, United States Patent No. 6,031,071; 5,824,520; 5,596,079; and 5,565,332 which are herein incorporated by reference at least for their material related to phage display and methods relate to combinatorial chemistry) 30 100. A preferred method for isolating proteins that have a given function is described by Roberts and Szostak (Roberts R.W. and Szostak J.W. Proc. Natl. Acad. Sci. USA, 94(23)12997-302 (1997). This combinatorial chemistry method couples the -31- WO 2006/074378 PCT/US2006/000474 functional power of proteins and the genetic power of nucleic acids. An RNA molecule is generated in which a puromycin molecule is covalently attached to the 3'-end of the RNA molecule. An in vitro translation of this modified RNA molecule causes the correct protein, encoded by the RNA to be translated. In addition, because of the attachment of the 5 puromycin, a peptdyl acceptor which cannot be extended, the growing peptide chain is attached to the puromycin which is attached to the RNA. Thus, the protein molecule is attached to the genetic material that encodes it. Normal in vitro selection procedures can now be done to isolate functional peptides. Once the selection procedure for peptide function is complete traditional nucleic acid manipulation procedures are performed to 10 amplify the nucleic acid that codes for the selected functional peptides. After amplification of the genetic material, new RNA is transcribed with puromycin at the 3'-end, new peptide is translated and another functional round of selection is performed. Thus, protein selection can be performed in an iterative manner just like nucleic acid selection techniques. The peptide which is translated is controlled by the sequence of the RNA 15 attached to the puromycin. This sequence can be anything from a random sequence engineered for optimum translation (i.e. no stop codons etc.) or it can be a degenerate sequence of a known RNA molecule to look for improved or altered function of a known peptide. The conditions for nucleic acid amplification and in vitro translation are well known to those of ordinary skill in the art and are preferably performed as in Roberts and 20 Szostak (Roberts R.W. and Szostak J.W. Proc. Natl. Acad. Sci. USA, 94(23)12997-302 (1997)). 101. Another preferred method for combinatorial methods designed to isolate peptides is described in Cohen et al. (Cohen B.A.,et al., Proc. Natl. Acad. Sci. USA 95(24):14272-7 (1998)). This method utilizes and modifies two-hybrid technology. Yeast 25 two-hybrid systems are useful for the detection and analysis of protein:protein interactions. The two-hybrid system, initially described in the yeast Saccharonyces cerevisiae, is a powerful molecular genetic technique for identifying new regulatory molecules, specific to the protein of interest (Fields and Song, Nature 340:245-6 (1989)). Cohen et al., modified this technology so that novel interactions between synthetic or engineered peptide 30 sequences could be identified which bind a molecule of choice. The benefit of this type of technology is that the selection is done in an intracellular environment. The method utilizes a library of peptide molecules that attached to an acidic activation domain. A -32- WO 2006/074378 PCT/US2006/000474 peptide of choice, for example an extracellular portion of AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1 is attached to a DNA binding domain of a transcriptional activation protein, such as Gal 4. By performing the Two hybrid technique on this type of system, molecules that bind the extracellular portion of 5 AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1 can be identified. 102. Using methodology well known to those of skill in the art, in combination with various combinatorial libraries, one can isolate and characterize those small molecules or macromolecules, which bind to or interact with the desired target. The relative binding 10 affinity of these compounds can be compared and optimum compounds identified using competitive binding studies, which are well known to those of skill in the art. 103. Techniques for making combinatorial libraries and screening combinatorial libraries to isolate molecules which bind a desired target are well known to those of skill in the art. Representative techniques and methods can be found in but are not limited to 15 United States patents 5,084,824, 5,288,514, 5,449,754, 5,506,337, 5,539,083, 5,545,568, 5,556,762, 5,565,324, 5,565,332, 5,573,905, 5,618,825, 5,619,680, 5,627,210, 5,646,285, 5,663,046, 5,670,326, 5,677,195, 5,683,899, 5,688,696, 5,688,997, 5,698,685, 5,712,146, 5,721,099, 5,723,598, 5,741,713, 5,792,431, 5,807,683, 5,807,754, 5,821,130, 5,831,014, 5,834,195, 5,834,318, 5,834,588, 5,840,500, 5,847,150, 5,856,107, 5,856,496, 5,859,190, 20 5,864,010, 5,874,443, 5,877,214, 5,880,972, 5,886,126, 5,886,127, 5,891,737, 5,916,899, 5,919,955, 5,925,527, 5,939,268, 5,942,387, 5,945,070, 5,948,696, 5,958,702, 5,958,792, 5,962,337, 5,965,719, 5,972,719, 5,976,894, 5,980,704, 5,985,356, 5,999,086, 6,001,579, 6,004,617, 6,008,321, 6,017,768, 6,025,371, 6,030,917, 6,040,193, 6,045,671, 6,045,755, 6,060,596, and 6,061,636. 25 104. Combinatorial libraries can be made from a wide array of molecules using a number of different synthetic techniques. For example, libraries containing fused 2,4 pyrimidinediones (United States patent 6,025,371) dihydrobenzopyrans (United States Patent 6,017,768and 5,821,130), amide alcohols (United States Patent 5,976,894), hydroxy-amino acid amides (United States Patent 5,972,719) carbohydrates (United States 30 patent 5,965,719), 1,4-benzodiazepin-2,5-diones (United States patent 5,962,337), cyclics (United States patent 5,958,792), biaryl amino acid amides (United States patent 5,948,696), thiophenes (United States patent 5,942,387), tricyclic Tetrahydroquinolines -33 - WO 2006/074378 PCT/US2006/000474 (United States patent 5,925,527), benzofurans (United States patent 5,919,955), isoquinolines (United States patent 5,916,899), hydantoin and thiohydantoin (United States patent 5,859,190), indoles (United States patent 5,856,496), imidazol-pyrido-indole and imidazol-pyrido-benzothiophenes (United States patent 5,856,107) substituted 2 5 methylene-2, 3-dihydrothiazoles (United States patent 5,847,150), quinolines (United States patent 5,840,500), PNA (United States patent 5,831,014), containing tags (United States patent 5,721,099), polyketides (United States patent 5,712,146), morpholino subunits (United States patent 5,698,685 and 5,506,337), sulfamides (United States patent 5,618,825), and benzodiazepines (United States patent 5,288,514). 10 105. As used herein combinatorial methods and libraries included traditional screening methods and libraries as well as methods and libraries used in interative processes. b) Computer assisted drug design 106. The disclosed compositions can be used as targets for any molecular 15 modeling technique to identify either the structure of the disclosed compositions- or to, identify potential or actual molecules, such as small molecules, which interact in a desired way with the disclosed compositions. The nucleic acids, peptides, and related molecules disclosed herein can be used as targets in any molecular modeling program or approach. 107. It is understood that when using the disclosed compositions in modeling 20 techmiques, molecules, such as macromolecular molecules, will be identified that have particular desired properties such as inhibition or stimulation or the target molecule's function. The molecules identified and isolated when using the disclosed compositions, such as, AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1, are also disclosed. Thus, the products produced using the molecular modeling 25 approaches that involve the disclosed compositions, such as, AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1, are also considered herein disclosed. 108. Thus, one way to isolate molecules that bind a molecule of choice is through rational design. This is achieved through structural information and computer modeling. 30 Computer modeling technology allows visualization of the three-dimensional atomic structure of a selected molecule and the rational design of new compounds that will interact with the molecule. The three-dimensional construct typically depends on data from x-ray - 34 - WO 2006/074378 PCT/US2006/000474 crystallographic analyses or NMR imaging of the selected molecule. The molecular dynamics require force field data. The computer graphics systems enable prediction of how a new compound will link to the target molecule and allow experimental manipulation of the structures of the compound and target molecule to perfect binding specificity. 5 Prediction of what the molecule-compound interaction will be when small changes are made in one or both requires molecular mechanics software and computationally intensive computers, usually coupled with user-friendly, menu-driven interfaces between the molecular design program and the user. 109. Examples of molecular modeling systems are the CHARMm and QUANTA 10 programs, Polygen Corporation, Waltham, MA. CHARMm performs the energy minimization and molecular dynamics functions. QUANTA performs the construction, graphic modeling, and analysis of molecular structure. QUANTA allows interactive construction, modification, visualization, and analysis of the behavior of molecules with each other. 15 110. A number of articles review computer modeling of drugs interactive with specific proteins, such as Rotivinen, et al., 1988 Acta Pharmaceutica Fennica 97, 159-166; Ripka, New Scientist 54-57 (June 16, 1988); McKinaly and Rossmann, 1989 Annu. Rev. Pharmacol._Toxiciol. 29, 111-122; Perry and Davies, QSAR: Quantitative Structure Activity Relationships in Drug Design pp. 189-193 (Alan R. Liss, Inc. 1989); Lewis and 20 Dean, 1989 Proc. R. Soc. Lond. 236, 125-140 and 141-162; and, with respect to a model enzyme for nucleic acid components, Askew, et al., 1989 J. Am. Chem. Soc. 111, 1082 1090. Other computer programs that screen and graphically depict chemicals are available from companies such as BioDesign, Inc., Pasadena, CA., Allelix, Inc, Mississauga, Ontario, Canada, and Hypercube, Inc., Cambridge, Ontario. Although these are primarily 25 designed for application to drugs specific to particular proteins, they can be adapted to design of molecules specifically interacting with specific regions of DNA or RNA, once that region is identified. 111. Although described above with reference to design and generation of compounds which could alter binding, one could also screen libraries of known 30 compounds, including natural products or synthetic chemicals, and biologically active materials, including proteins, for compounds which alter substrate binding or enzymatic activity. -35-- WO 2006/074378 PCT/US2006/000474 C. Compositions 112. Disclosed are the components to be used to prepare the disclosed compositions as well as the compositions themselves to be used within the methods disclosed herein. These and other materials are disclosed herein, and it is understood that 5 when combinations, subsets, interactions, groups, etc. of these materials are disclosed that while specific reference of each various individual and collective combinations and permutation of these compounds may not be explicitly disclosed, each is specifically contemplated and described herein. For example, if a particular AR is disclosed and discussed and a number of modifications that can be made to a number of molecules 10 including the AR are discussed, specifically contemplated is each and every combination and permutation of AR and the modifications that are possible unless specifically indicated to the contrary. Thus, if a class of molecules A, B, and C are disclosed as well as a class of molecules D, E, and F and an example of a combination molecule, A-D is disclosed, then even if each is not individually recited each is individually and collectively contemplated 15 meaning combinations, A-E, A-F, B-D, B-E, B-F, C-D, C-E, and C-F are considered disclosed. Likewise, any subset or combination of these is also disclosed. Thus, for example, the sub-group of A-E, B-F, and C-E would be considered disclosed. This concept applies to all aspects of this application including, but not limited to, steps in methods of making and using the disclosed compositions. Thus, if there are a variety of additional 20 steps that can be performed it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the disclosed methods. 1. Homology/identity 113. It is understood that one way to define any known variants and derivatives or 25 those that might arise, of the disclosed genes and proteins herein is through defining the variants and derivatives in terms of homology to specific known sequences. For example SEQ ID NO: 2 sets forth a particular sequence of an AR and SEQ ED NO: 1 sets forth a particular sequence of the protein encoded by SEQ ID NO: 2, an AR protein. Specifically disclosed are variants of these and other genes and proteins herein disclosed which have at 30 least, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99 percent homology to the stated sequence. Those of skill in the art readily understand how to determine the homology of two proteins or nucleic acids, such as -36- WO 2006/074378 PCT/US2006/000474 genes. For example, the homology can be calculated after aligning the two sequences so that the homology is at its highest level. 114. Another way of calculating homology can be performed by published algorithms. Optimal alignment of sequences for comparison may be conducted by the local 5 homology algorithm of Smith and Waterman Adv. Appl. Math. 2: 482 (1981), by the homology alignment algorithm of Needleman and Wunsch, J. MoL Biol. 48: 443 (1970), by the search for similarity method of Pearson and Lipman, Proc. Natl. Acad. Sci. U.S.A. 85: 2444 (1988), by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer 10 Group, 575 Science Dr., Madison, WI), or by inspection. 115. The same types of homology can be obtained for nucleic acids by for example the algorithms disclosed in Zuker, M. Science 244:48-52, 1989, Jaeger et al. Proc. Nati. Acad. Sci. USA 86:7706-7710, 1989, Jaeger et al. Methods Enzymol. 183:281-306, 1989 which are herein incorporated by reference for at least material related to nucleic acid 15 alignment. 2. Hybridization/selective hybridization 116. The term hybridization typically means a sequence driven interaction between at least two nucleic acid molecules, such as a primer or a probe and a gene. Sequence driven interaction means an interaction that occurs between two nucleotides or 20 nucleotide analogs or nucleotide derivatives in a nucleotide specific manner. For example, G interacting with C or A interacting with T are sequence driven interactions. Typically sequence driven interactions occur on the Watson-Crick face or Hoogsteen face of the nucleotide. The hybridization of two nucleic acids is affected by a number of conditions and parameters known to those of skill in the art. For example, the salt concentrations, pH, 25 and temperature of the reaction all affect whether two nucleic acid molecules will hybridize. 117. Parameters for selective hybridization between two nucleic acid molecules are well known to those of skill in the art. For example, in some embodiments selective hybridization conditions can be defined as stringent hybridization conditions. For 30 example, stringency of hybridization is controlled by both temperature and salt concentration of either or both of the hybridization and washing steps. For example, the conditions of hybridization to achieve selective hybridization may involve hybridization in -37- WO 2006/074378 PCT/US2006/000474 high ionic strength solution (6X SSC or 6X SSPE) at a temperature that is about 12-25 0 C below the Tm (the melting temperature at which half of the molecules dissociate from their hybridization partners) followed by washing at a combination of temperature and salt concentration chosen so that the washing temperature is about 5'C to 20'C below the Tm. 5 The temperature and salt conditions are readily determined empirically in preliminary experiments in which samples of reference DNA immobilized on filters are hybridized to a labeled nucleic acid of interest and then washed under conditions of different stringencies. Hybridization temperatures are typically higher for DNA-RNA and RNA-RNA hybridizations. The conditions can be used as described above to achieve stringency, or as 10 is known in the art. (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, New York, 1989; Kunkel et al. Methods Enzymol. 1987:154:367, 1987 which is herein incorporated by reference for material at least related to hybridization of nucleic acids). A preferable stringent hybridization condition for a DNA:DNA hybridization can be at about 68'C (in aqueous 15 solution) in 6X SSC or 6X SSPE followed by washing at 68'C. Stringency of hybridization and washing, if desired, can be reduced accordingly as the degree of complementarity desired is decreased, and further, depending upon the G-C or A-T richness of any area wherein variability is searched for. Likewise, stringency of hybridization and washing, if desired, can be increased accordingly as homology desired is 20 increased, and further, depending upon the G-C or A-T richness of any area wherein high homology is desired, all as known in the art. 118. Another way to define selective hybridization is by looking at the amount (percentage) of one of the nucleic acids bound to the other nucleic acid. For example, in some embodiments selective hybridization conditions would be when at least about, 60, 65, 25 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 percent of the limiting nucleic acid is bound to the non-limiting nucleic acid. Typically, the non-limiting primer is in for example, 10 or 100 or 1000 fold excess. This type of assay can be performed at under conditions where both the limiting and non-limiting primer are for example, 10 fold or 100 fold or 1000 fold below their kd, or 30 where only one of the nucleic acid molecules is 10 fold or 100 fold or 1000 fold or where one or both nucleic acid molecules are above their kd. -38- WO 2006/074378 PCT/US2006/000474 119. Another way to define selective hybridization is by looking at the percentage of primer that gets enzymatically manipulated under conditions where hybridization is required to promote the desired enzymatic manipulation. For example, in some embodiments selective hybridization conditions would be when at least about, 60, 65, 70, 5 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 percent of the primer is enzymatically manipulated under conditions which promote the enzymatic manipulation, for example if the enzymatic manipulation is DNA extension, then selective hybridization conditions would be when at least about 60, 65, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 10 93, 94, 95, 96, 97, 98, 99, 100 percent of the primer molecules are extended. Preferred conditions also include those suggested by the manufacturer or indicated in the art as being appropriate for the enzyme performing the manipulation. 120. Just as with homology, it is understood that there are a variety of methods herein disclosed for determining the level of hybridization between two nucleic acid 15 molecules. It is understood that these methods and conditions may provide different percentages of hybridization between two nucleic acid molecules, but unless otherwise indicated meeting the parameters of any of the methods would be sufficient. For example if 80% hybridization was required and as long as hybridization occurs within the required parameters in any one of these methods it is considered disclosed herein. 20 121. It is understood that those of skill in the art understand that if a composition or method meets any one of these criteria for determining hybridization either collectively or singly it is a composition or method that is disclosed herein. a) Sequences 122. There are a variety of sequences related to the AR, RB, ARA54, ARA55, 25 ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1, for example, and other disclosed genes having the following Genbank Accession Numbers: (SEQ ID NOs:1 and 2) human AR protein and DNA, NM_000044; (SEQ ID NOs:3 and 4) Mouse AR protein and DNA, X59592; (SEQ ID NOs:5 and 6) Mouse AR protein and DNA, M37890; (SEQ ID NOs:7 and 8) Human ARA70 protein and DNA, L49399; (SEQ ID NOs:9 and 10) Human 30 ARA 54 protein and DNA, AF060544; (SEQ ID NOs: 11 and 12) Human ARA55 protein and DNA, AFI 16343; (SEQ ID NOs:13 and 14) Human ARA24 protein and DNA, AF052578; (SEQ ID NOs:15 and 16) Human ARA267-a protein and DNA, AF380302; -39- WO 2006/074378 PCT/US2006/000474 (SEQ ID NOs:17 and 18) Human ARA267-b protein and DNA, AY049721; (SEQ ID NOs:19 and 20) Human supervillin protein and DNA, AF051850; (SEQ ID NOs:21 and 22) Mouse gelsolin protein and DNA, J04953; (SEQ ID NOs:23 and 24) Human retinoblastoma protein and DNA, M28419; (SEQ ID NOs:25 and 26) Human gelsolin 5 protein and DNA, MGC:39262; (SEQ ID NOs:27 and 28) Human steroid receptor coactivator-1 SRC-1) mRNA, protein and DNA, U90661, these sequences and others are herein incorporated by reference in their entireties as well as for individual subsequences contained therein. 123. One particular sequence set forth in SEQ ID NO:1 and having Genbank 10 accession number NM_000044 is used herein, as an example, to exemplify the disclosed compositions and methods. It is understood that the description related to this sequence is applicable to any sequence disclosed herein unless specifically indicated otherwise. Those of skill in the art understand how to resolve sequence discrepancies and differences and to adjust the compositions and methods relating to a particular sequence to other related 15 sequences (i.e. sequences of AR). Primers and/or probes can be designed for any AR sequence given the information disclosed herein and known in the art. 3. Delivery of the compositions to cells 124. There are a number of compositions and methods which can be used to deliver nucleic acids to cells, either in vitro or in vivo. These methods and compositions 20 can largely be broken down into two classes: viral based delivery systems and non-viral based delivery systems. For example, the nucleic acids can be delivered through a number of direct delivery systems such as, electroporation, lipofection, calcium phosphate precipitation, plasmids, viral vectors, viral nucleic acids, phage nucleic acids, phages, cosmids, or via transfer of genetic material in cells or carriers such as cationic liposomes. 25 Appropriate means for transfection, including viral vectors, chemical transfectants, or physico-mechanical methods such as electroporation and direct diffusion of DNA, are described by, for example, Wolff, J. A., et al., Science, 247, 1465-1468, (1990); and Wolff, J. A. Nature, 352, 815-818, (1991) Such methods are well known in the art and readily adaptable for use with the compositions and methods described herein. In certain cases, 30 the methods will be modifed to specifically function with large DNA molecules. Further, these methods can be used to target certain diseases and cell populations by using the targeting characteristics of the carrier. - 40- WO 2006/074378 PCT/US2006/000474 a) Nucleic acid based delivery systems 125. Transfer vectors can be any nucleotide construction used to deliver genes into cells (e.g., a plasmid), or as part of a general strategy to deliver genes, e.g., as part of recombinant retrovirus or adenovirus (Ram et al. Cancer Res. 53:83-88, (1993)). 5 126. As used herein, plasmid or viral vectors are agents that transport the disclosed nucleic acids, such as Ab, RB, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1 into the cell without degradation and include a promoter yielding expression of the gene in the cells into which it is delivered. Viral vectors are, for example, Adenovirus, Adeno-associated virus, Herpes virus, Vaccinia virus, Polio virus, 10 AIDS virus, neuronal trophic virus, Sindbis and other RNA viruses, including these viruses with the HIV backbone. Also preferred are any viral families which share the properties of these viruses which make them suitable for use as vectors. Retroviruses include Murine Maloney Leukemia virus (MMLV) and retroviruses that express the desirable properties of MMLV as a vector. Retroviral vectors are able to carry a larger genetic payload, i.e., a 15 transgene or marker gene, than other viral vectors, and for this reason are a commonly used vector. However, they are not as useful in non-proliferating cells. Adenovirus vectors are relatively stable and easy to work with, have high titers, and can be delivered in aerosol formulation, and can transfect non-dividing cells. Pox viral vectors are large and have several sites for inserting genes, they are thermostable and can be stored at room 20 temperature. A preferred embodiment is a viral vector which has been engineered so as to suppress the immune response of the host organism, elicited by the viral antigens. Preferred vectors of this type will carry coding regions for Interleukin 8 or 10. 127. Viral vectors can have higher transaction (ability to introduce genes) abilities than chemical or physical methods to introduce genes into cells. Typically, viral vectors 25 contain nonstructural early genes, structural late genes, an RNA polymerase III transcript, inverted terminal repeats necessary for replication and encapsidation, and promoters to control the transcription and replication of the viral genome. When engineered as vectors, viruses typically have one or more of the early genes removed and a gene or gene/promotor cassette is inserted into the viral genome in place of the removed viral DNA. Constructs of 30 this type can carry up to about 8 kb of foreign genetic material. The necessary functions of the removed early genes are typically supplied by cell lines which have been engineered to express the gene products of the early genes in trans. -41- WO 2006/074378 PCT/US2006/000474 (1) Retroviral Vectors 128. A retrovirus is an animal virus belonging to the virus family of Retroviridae, including any types, subfamilies, genus, or tropisms. Retroviral vectors, in general, are described by Verma, I.M., Retroviral vectors for gene transfer. In Microbiology-1985, 5 American Society for Microbiology, pp. 229-232, Washington, (1985), which is incorporated by reference herein. Examples of methods for using retroviral vectors for gene therapy are described in U.S. Patent Nos. 4,868,116 and 4,980,286; PCT applications WO 90/02806 and WO 89/07136; and Mulligan, (Science 260:926-932 (1993)); the teachings of which are incorporated herein by reference. 10 129. A retrovirus is essentially a package which has packed into it nucleic acid cargo. The nucleic acid cargo carries with it a packaging signal, which ensures that the replicated daughter molecules will be efficiently packaged within the package coat. In addition to the package signal, there are a number of molecules which are needed in cis, for the replication, and packaging of the replicated virus. Typically a retroviral genome, 15 contains the gag, pol, and env genes which are involved in the making of the protein coat. It is the gag, pol, and env genes which are typically replaced by the foreign DNA that it is to be transferred to the target cell. Retrovirus vectors typically contain a packaging signal for incorporation into the package coat, a sequence which signals the start of the gag transcription unit, elements necessary for reverse transcription, including a primer binding 20 site to bind the tRNA primer of reverse transcription, tenninal repeat sequences that guide the switch of RNA strands during DNA synthesis, a purine rich sequence 5' to the 3' LTR that serves as the priming site for the synthesis of the second strand of DNA synthesis, and specific sequences near the ends of the LTRs that enable the insertion of the DNA state of the retrovirus to insert into the host genome. The removal of the gag, pol, and env genes 25 allows for about 8 kb of foreign sequence to be inserted into the viral genome, become reverse transcribed, and upon replication be packaged into a new retroviral particle. This amount of nucleic acid is sufficient for the delivery of one to many genes depending on the size of each transcript. It is preferable to include either positive or negative selectable markers along with other genes in the insert. 30 130. Since the replication machinery and packaging proteins in most retroviral vectors have been removed (gag, pol, and env), the vectors are typically generated by placing them into a packaging cell line. A packaging cell line is a cell line which has been -42- WO 2006/074378 PCT/US2006/000474 transfected or transformed with a retrovirus that contains the replication and packaging machinery, but lacks any packaging signal. When the vector carrying the DNA of choice is transfected into these cell lines, the vector containing the gene of interest is replicated and packaged into new retroviral particles, by the machinery provided in cis by the helper cell. 5 The genomes for the machinery are not packaged because they lack the necessary signals. (2) Adenoviral Vectors 131. The construction of replication-defective adenoviruses has been described (Berkner et al., J. Virology 61:1213-1220 (1987); Massie et al., Mol. Cell. Biol. 6:2872 2883 (1986); Haj-Ahmad et al., J. Virology 57:267-274 (1986); Davidson et al., J. 10 Virology 61:1226-1239 (1987); Zhang "Generation and identification of recombinant adenovirus by liposome-mediated transfection and PCR analysis" BioTechniques 15:868 872 (1993)). The benefit of the use of these viruses as vectors is that they are limited in the extent to which they can spread to other cell types, since they can replicate within an initial infected cell, but are unable to form new infectious viral particles. Recombinant 15 adenoviruses have been shown to achieve high efficiency gene transfer after direct, in vivo delivery to airway epithelium, hepatocytes, vascular endothelium, CNS parenchyma and a number of other tissue sites (Morsy, J. Clin. Invest. 92:1580-1586 (1993); Kirshenbaum, J. Clin. Invest. 92:381-387 (1993); Roessler, J. Clin. Invest. 92:1085-1092 (1993); Moullier, Nature Genetics 4:154-159 (1993); La Salle, Science 259:988-990 (1993); Gomez-Foix, J. 20 Biol. Chem. 267:25129-25134 (1992); Rich, Human Gene Therapy 4:461-476 (1993); Zabner, Nature Genetics 6:75-83 (1994); Guzman, Circulation Research 73:1201-1207 (1993); Bout, Human Gene Therapy 5:3-10 (1994); Zabner, Cell 75:207-216 (1993); Caillaud, Eur. J. Neuroscience 5:1287-1291 (1993); and Ragot, J. Gen. Virology 74:501 507 (1993)). Recombinant adenoviruses achieve gene transduction by binding to specific 25 cell surface receptors, after which the virus is internalized by receptor-mediated endocytosis, in the same manner as wild type or replication-defective adenovirus (Chardonnet and Dales, Virology 40:462-477 (1970); Brown and Burlingham, J. Virology 12:386-396 (1973); Svensson and Persson, J. Virology 55:442-449 (1985); Seth, et al., J. Virol. 51:650-655 (1984); Seth, et al., Mol. Cell. Biol. 4:1528-1533 (1984); Varga et al., J. 30 Virology 65:6061-6070 (1991); Wickham et al., Cell 73:309-319 (1993)). 132. A viral vector can be one based on an adenovirus which has had the El gene removed and these virons are generated in a cell line such as the human 293 cell line. In -43 - WO 2006/074378 PCT/US2006/000474 another preferred embodiment both the El and E3 genes are removed from the adenovirus genome. (3) Adeno-associated viral vectors 133. Another type of viral vector is based on an adeno-associated virus (AAV). 5 This defective parvovirus is a preferred vector because it can infect many cell types and is nonpathogenic to humans. AAV type vectors can transport about 4 to 5 kb and wild type AAV is known to stably insert into chromosome 19. Vectors which contain this site specific integration property are preferred. An especially preferred embodiment of this type of vector is the P4.1 C vector produced by Avigen, San Francisco, CA, which can 10 contain the herpes simplex virus thymidine kinase gene, HSV-tk, and/or a marker gene, such as the gene encoding the green fluorescent protein, GFP. 134. In another type of AAV virus, the AAV contains a pair of inverted terminal repeats (ITRs) which flank at least one cassette containing a promoter which directs cell specific expression operably linked to a heterologous gene. Heterologous in this context 15 refers to any nucleotide sequence or gene which is not native to the AAV or B 19 parvovirus. 135. Typically the AAV and B19 coding regions have been deleted, resulting in a safe, noncytotoxic vector. The AAV ITRs, or modifications thereof, confer infectivity and site-specific integration, but not cytotoxicity, and the promoter directs cell-specific 20 expression. United states Patent No. 6,261,834 is herein incorproated by reference for material related to the AAV vector. 136. The vectors of the present invention thus provide DNA molecules which are capable of integration into a mammalian chromosome without substantial toxicity. 137. The inserted genes in viral and retroviral usually contain promoters, and/or 25 enhancers to help control the expression of the desired gene product. A promoter is generally a sequence or sequences of DNA that function when in a relatively fixed location in regard to the transcription start site. A promoter contains core elements required for basic interaction of RNA polymerase and transcription factors, and may contain upstream elements and response elements. 30 (4) Large payload viral vectors 138. Molecular genetic experiments with large human herpesviruses have provided a means whereby large heterologous DNA fragments can be cloned, propagated -44- WO 2006/074378 PCT/US2006/000474 and established in cells permissive for infection with herpesviruses (Sun et al., Nature genetics 8: 33-41, 1994; Coffer and Robertson,.Curr Opin Mol Ther 5: 633-644, 1999). These large DNA viruses (herpes simplex virus (HSV) and Epstein-Barr virus (EBV), have the potential to deliver fragments of human heterologous DNA > 150 kb to specific cells. 5 EBV recombinants can maintain large pieces of DNA in the infected B-cells as episomal DNA. Individual clones carried human genomic inserts up to 330 kb appeared genetically stable The maintenance of these episomes requires a specific EBV nuclear protein, EBNAl, constitutively expressed during infection with EBV. Additionally, these vectors can be used for transfection, where large amounts of protein can be generated transiently in 10 vitro. Herpesvirus amplicon systems are also being used to package pieces of DNA > 220 kb and to infect cells that can stably maintain DNA as episomes. 139. Other useful systems include, for example, replicating and host-restricted non-replicating vaccinia virus vectors. b) Non-nucleic acid based systems 15 140. The disclosed compositions can be delivered to the target cells in a variety of ways. For example, the compositions can be delivered through electroporation, or through lipofection, or through calcium phosphate precipitation. The delivery mechanism chosen will depend in part on the type of cell targeted and whether the delivery is occurring for example in vivo or in vitro. 20 141. Thus, the compositions can comprise, in addition to the disclosed AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, gelsolin, supervillin, and SRC-1 or vectors for example, lipids such as liposomes, such as cationic liposomes (e.g., DOTMA, DOPE, DC-cholesterol) or anionic liposomes. Liposomes can further comprise proteins to facilitate targeting a particular cell, if desired. Administration of a composition comprising 25 a compound and a cationic liposome can be administered to the blood afferent to a target organ or inhaled into the respiratory tract to target cells of the respiratory tract. Regarding liposomes, see, e.g., Brigham et al. Am. J. Resp. Cell. Mo. Bio. 1:95-100 (1989); Felgner et al. Proc. Nati. Acad. Sci U.S.A. 84:7413-7417 (1987); U.S. Pat. No.4,897,355. Furthermore, the compound can be administered as a component of a microcapsule that can 30 be targeted to specific cell types, such as macrophages, or where the diffusion of the compound or delivery of the compound from the microcapsule is designed for a specific rate or dosage. -45- WO 2006/074378 PCT/US2006/000474 142. In the methods described above which include the administration and uptake of exogenous DNA into the cells of a subject (i.e., gene transduction or transfection), delivery of the compositions to cells can be via a variety of mechanisms. As one example, delivery can be via a liposome, using commercially available liposome preparations such 5 as LIPOFECTIN, LIPOFECTAMINE (GIBCO-BRL, Inc., Gaithersburg, MD), SUPERFECT (Qiagen, Inc. Hilden, Germany) and TRANSFECTAM (Promega Biotec, Inc., Madison, WI), as well as other liposomes developed according to procedures standard in the art. In addition, the nucleic acid or vector of this invention can be delivered in vivo by electroporation, the technology for which is available from Genetronics, Inc. (San 10 Diego, CA) as well as by means of a SONOPORATION machine (ImaRx Pharmaceutical Corp., Tucson, AZ). 143. The materials may be in solution, suspension (for example, incorporated into microparticles, liposomes, or cells). These may be targeted to a particular cell type via antibodies, receptors, or receptor ligands. The following references are examples of the use 15 of this technology to target specific proteins to tumor tissue (Senter, et al., Bioconjugate Chem., 2:447-451, (1991); Bagshawe, K.D., Br. J. Cancer, 60:275-281, (1989); Bagshawe, et al., Br. J. Cancer, 58:700-703, (1988); Senter, et al., Bioconjugate Chem., 4:3-9, (1993); Battelli, et al., Cancer Immunol. Immunother., 35:421-425, (1992); Pietersz and McKenzie, Immunolog. Reviews, 129:57-80, (1992); and Roffler, et al., Biochem. Pharmacol, 20 42:2062-2065, (1991)). These techniques can be used for a variety of other specific cell types. Vehicles such as "stealth" and other antibody conjugated liposomes (including lipid mediated drug targeting to colonic carcinoma), receptor mediated targeting of DNA through cell specific ligands, lymphocyte directed tumor targeting, and highly specific therapeutic retroviral targeting of murine glioma cells in vivo. The following references are 25 examples of the use of this technology to target specific proteins to tumor tissue (Hughes et al., Cancer Research, 49:6214-6220, (1989); and Litzinger and Huang, Biochimica et Biophysica Acta, 1104:179-187, (1992)). In general, receptors are involved in pathways of endocytosis, either constitutive or ligand induced. These receptors cluster in clathrin-coated pits, enter the cell via clathrin-coated vesicles, pass through an acidified 30 endosome in which the receptors are sorted, and then either recycle to the cell surface, become stored intracellularly, or are degraded in lysosomes. The internalization pathways serve a variety of functions, such as nutrient uptake, removal of activated proteins, -46- WO 2006/074378 PCT/US2006/000474 clearance of macromolecules, opportunistic entry of viruses and toxins, dissociation and degradation of ligand, and receptor-level regulation. Many receptors follow more than one intracellular pathway, depending on the cell type, receptor concentration, type of ligand, ligand valency, and ligand concentration. Molecular and cellular mechanisms of 5 receptor-mediated endocytosis has been reviewed (Brown and Greene, DNA and Cell Biology 10(6) 399-409 (1991)). 144. Nucleic acids that are delivered to cells which are to be integrated into the host cell genome, typically contain integration sequences. These sequences are often viral related sequences, particularly when viral based systems are used. These viral integration 10 systems can also be incorporated into nucleic acids which are to be delivered using a non nucleic acid based system of delivery, such as a liposome, so that the nucleic acid contained in the delivery system can be come integrated into the host genome. 145. Other general techniques for integration into the host genome include, for example, systems designed to promote homologous recombination with the host genome. 15 These systems typically rely on a sequence flanking the nucleic acid to be expressed that has enough homology with a target sequence within the host cell genome that recombination between the vector nucleic acid and the target nucleic acid takes place, causing the delivered nucleic acid to be integrated into the host genome. These systems and the methods necessary to promote homologous recombination are known to those of 20 skill in the art. c) In vivolex vivo 146. As described above, the compositions can be administered in a pharmaceutically acceptable carrier and can be delivered to the subject' s cells in vivo and/or ex vivo by a variety of mechanisms well known in the art (e.g., uptake of naked 25 DNA, liposome fusion, intramuscular injection of DNA via a gene gun, endocytosis and the like). 147. If ex vivo methods are employed, cells or tissues can be removed and maintained outside the body according to standard protocols well known in the art. The compositions can be introduced into the cells via any gene transfer mechanism, such as, for 30 example, calcium phosphate mediated gene delivery, electroporation, microinjection or proteoliposomes. The transduced cells can then be infused (e.g., in a pharmaceutically acceptable carrier) or homotopically transplanted back into the subject per standard -47- WO 2006/074378 PCT/US2006/000474 methods for the cell or tissue type. Standard methods are known for transplantation or infusion of various cells into a subject. 4. Expression systems 148. The nucleic acids that are delivered to cells typically contain expression 5 controlling systems. For example, the inserted genes in viral and retroviral systems usually contain promoters, and/or enhancers to help control the expression of the desired gene product. A promoter is generally a sequence or sequences of DNA that function when in a relatively fixed location in regard to the transcription start site. A promoter contains core elements required for basic interaction of RNA polymerase and transcription factors, and 10 may contain upstream elements and response elements. a) Viral Promoters and Enhancers 149. Preferred promoters controlling transcription from vectors in mammalian host cells may be obtained from various sources, for example, the genomes of viruses such as: polyoma, Simian Virus 40 (SV40), adenovirus, retroviruses, hepatitis-B virus and most 15 preferably cytomegalovirus, or from heterologous mammalian promoters, e.g. beta actin promoter. The early and late promoters of the SV40 virus are conveniently obtained as an SV40 restriction fragment which also contains the SV40 viral origin of replication (Fiers et al., Nature, 273: 113 (1978)). The immediate early promoter of the human cytomegalovirus is conveniently obtained as a HindII E restriction fragment (Greenway, 20 P.J. et al., Gene 18: 355-360 (1982)). Of course, promoters from the host cell or related species also are useful herein. 150. Enhancer generally refers to a sequence of DNA that functions at no fixed distance from the transcription start site and can be either 5' (Laimins, L. et al., Proc. Natl. Acad. Sci. 78: 993 (1981)) or 3' (Lusky, M.L., et al., Mol. Cell Bio. 3: 1108 (1983)) to 25 the transcription unit. Furthermore, enhancers can be within an intron (Banerji, J.L. et al., Cell 33: 729 (1983)) as well as within the coding sequence itself (Osborne, T.F., et al., Mol. Cell Bio. 4: 1293 (1984)). They are usually between 10 and 300 bp in length, and they function in cis. Enhancers f unction to increase transcription from nearby promoters. Enhancers also often contain response elements that mediate the regulation of 30 transcription. Promoters can also contain response elements that mediate the regulation of transcription. Enhancers often determine the regulation of expression of a gene. While many enhancer sequences are now known from mammalian genes (globin, elastase, -48- WO 2006/074378 PCT/US2006/000474 albumin, fetoprotein and insulin), typically one will use an enhancer from a eukaryotic cell virus for general expression. Preferred examples are the SV40 enhancer on the late side of the replication origin (bp 100-270), the cytomegalovirus early promoter enhancer, the polyoma enhancer on the late side of the replication origin, and adenovirus enhancers. 5 151. The promotor and/or enhancer may be specifically activated either by light or specific chemical events which trigger their function. Systems can be regulated by reagents such as tetracycline and dexamethasone. There are also ways to enhance viral vector gene expression by exposure to irradiation, such as gamma irradiation, or alkylating chemotherapy drugs. 10 152. In certain embodiments the promoter and/or enhancer region can act as a constitutive promoter and/or enhancer to maximize expression of the region of the transcription unit to be transcribed. In certain constructs the promoter and/or enhancer region may be active in all eukaryotic cell types, even if it is only expressed in a particular type of cell at a particular time. A preferred promoter of this type is the CMV promoter 15 (650 bases). Other preferred promoters are SV40 promoters, cytomegalovirus (full length promoter), and retroviral vector LTF. 153. It has been shown that all specific regulatory elements can be cloned and used to construct expression vectors that are selectively expressed in specific cell types such as melanoma cells. The glial fibrillary acetic protein (GFAP) promoter has been used 20 to selectively express genes in cells of glial origin. 154. Expression vectors used in eukaryotic host cells (yeast, fungi, insect, plant, animal, human, or nucleated cells) may also contain sequences necessary for the termination of transcription which may affect mRNA expression. These regions are transcribed as polyadenylated segments in the untranslated portion of the mRNA encoding 25 tissue factor protein. The 3' untranslated regions also include transcription termination sites. It is preferred that the transcription unit also contain a polyadenylation region. One benefit of this region is that it increases the likelihood that the transcribed unit will be processed and transported like mRNA. The identification and use of polyadenylation signals in expression constructs is well established. It is preferred that homologous 30 polyadenylation signals be used in the transgene constructs. In certain transcription units, the polyadenylation region is derived from the SV40 early polyadenylation signal and consists of about 400 bases. It is also preferred that the transcribed units contain other -49 - WO 2006/074378 PCT/US2006/000474 standard sequences alone or in combination with the above sequences improve expression from, or stability of, the construct. b) Markers 155. The viral vectors can include nucleic acid sequence encoding a marker 5 product. This marker product is used to determine if the gene has been delivered to the cell and once delivered is being expressed. Preferred marker genes are the E. Coli lacZ gene, which encodes B-galactosidase, and green fluorescent protein. 156. In some embodiments the marker may be a selectable marker. Examples of suitable selectable markers for mammalian cells are dihydrofolate reductase (DHFR), 10 thymidine kinase, neomycin, neomycin analog G418, hydromycin, and puromycin. When such selectable markers are successfully transferred into a mammalian host cell, the transformed mammalian host cell can survive if placed under selective pressure. There are two widely used distinct categories of selective regimes. The first category is based on a cell's metabolism and the use of a mutant cell line which lacks the ability to grow 15 independent of a supplemented media. Two examples are: CHO DHFR- cells and mouse LTK- cells. These cells lack the ability to grow without the addition of such nutrients as thymidine or hypoxanthine. Because these cells lack certain genes necessary for a complete nucleotide synthesis pathway, they cannot survive unless the missing nucleotides are provided in a supplemented media. An alternative to supplementing the media is to 20 introduce an intact DHFR or TK gene into cells lacking the respective genes, thus altering their growth requirements. Individual cells which were not transformed with the DHFR or TK gene will not be capable of survival in non-supplemented media. 157. The second category is dominant selection which refers to a selection scheme used in any cell type and does not require the use of a mutant cell line. These schemes 25 typically use a drug to arrest growth of a host cell. Those cells which have a novel gene would express a protein conveying drug resistance and would survive the selection. Examples of such dominant selection use the drugs neomycin, (Southern P. and Berg, P., J Molec. Appl. Genet. 1: 327 (1982)), mycophenolic acid, (Mulligan, R.C. and Berg, P. Science 209: 1422 (1980)) or hygromycin, (Sugden, B. et al., Mol. Cell. Biol. 5: 410-413 30 (1985)). The three examples employ bacterial genes under eukaryotic control to convey resistance to the appropriate drug G418 or neomycin (geneticin), xgpt (mycophenolic acid) or hygromycin, respectively. Others include the neomycin analog G418 and puramycin. -50- WO 2006/074378 PCT/US2006/000474 5. Peptides a) Protein variants 158. As discussed herein there are numerous variants of the AR protein and gelsolin protein that are known and herein contemplated. In addition, to the known 5 functional AR strain variants there are derivatives of the AR proteins which also function in the disclosed methods and compositions. Protein variants and derivatives are well understood to those of skill in the art and can involve amino acid sequence modifications. For example, amino acid sequence modifications typically fall into one or more of three classes: substitutional, insertional, or deletional variants. Insertions include amino and/or 10 carboxyl terminal fusions as well as intrasequence insertions of single or multiple amino acid residues. Insertions ordinarily will be smaller insertions than those of amino or carboxyl terminal fusions, for example, on the order of one to four residues. Immunogenic fusion protein derivatives, such as those described in the examples, are made by fusing a polypeptide sufficiently large to confer immunogenicity to the target sequence by cross 15 linking in vitro or by recombinant cell culture transformed with DNA encoding the fusion. Deletions are characterized by the removal of one or more amino acid residues from the protein sequence. Typically, no more than about from 2 to 6 residues are deleted at any one site within the protein molecule. These variants ordinarily are prepared by site specific mutagenesis of nucleotides in the DNA encoding the protein, thereby producing DNA 20 encoding the variant, and thereafter expressing the DNA in recombinant cell culture. Techniques for making substitution mutations at predetermined sites in DNA having a known sequence are well known, for example M13 primer mutagenesis and PCR mutagenesis. Amino acid substitutions are typically of single residues, but can occur at a number of different locations at once; insertions usually will be on the order of about from 25 1 to 10 amino acid residues; and deletions will range about from 1 to 30 residues. Deletions or insertions preferably are made in adjacent pairs, i.e. a deletion of 2 residues or insertion of 2 residues. Substitutions, deletions, insertions or any combination thereof may be combined to arrive at a final construct. The mutations must not place the sequence out of reading frame and preferably will not create complementary regions that could produce 30 secondary mRNA structure. Substitutional variants are those in which at least one residue has been removed and a different residue inserted in its place. Such substitutions generally -51- WO 2006/074378 PCT/US2006/000474 are made in accordance with the following Tables 1 and 2 and are referred to as conservative substitutions. 159. TABLE 1:Amino Acid Abbreviations Amino Acid Abbreviations alanine Ala A allosoleucine AIle arginine Arg R asparagine Asn N aspartic acid Asp D cysteine Cys C glutamic acid Glu E glutamine Gln Q glycine Gly G histidine His H isolelucine Ile I leucine Leu L lysine Lys K phenylalanine Phe F proline Pro P pyroglutamic pGlu acidp serine Ser S threonine Thr T tyrosine Tyr Y tryptophan Trp W valine Val V TABLE 2:Amino Acid Substitutions Original Residue Exemplary Conservative Substitutions, others are known in the art. Ala; Ser Arg;Lys; Gln Asn; Gln; His Asp; Glu Cys; Ser Gln; Asn, Lys Glu; Asp Gly; Pro His; Asn; Gln Ile; Leu; Val Leu; Ile; Val Lys; Arg; Gln; Met; Leu; Ile Phe; Met; Leu; Tyr Ser; Thr Thr; Ser -52- WO 2006/074378 PCT/US2006/000474 Trp; Tyr Tyr; Trp; Phe Val; Ile; Leu 160. Substantial changes in function or immunological identity are made by selecting substitutions that are less conservative than those in Table 2, i.e., selecting residues that differ more significantly in their effect on maintaining (a) the structure of the polypeptide backbone in the area of the substitution, for example as a sheet or helical 5 conformation, (b) the charge or hydrophobicity of the molecule at the target site, or (c) the bulk of the side chain. The substitutions which in general are expected to produce the greatest changes in the protein properties will be those in which (a) a hydrophilic residue, e.g. seryl or threonyl, is substituted for (or by) a hydrophobic residue, e.g. leucyl, isoleucyl, phenylalanyl, valyl or alanyl; (b) a cysteine or proline is substituted for (or by) any other 10 residue; (c) a residue having an electropositive side chain, e.g., lysyl, arginyl, or histidyl, is substituted for (or by) an electronegative residue, e.g., glutanyl or aspartyl; or (d) a residue having a bulky side chain, e.g., phenylalanine, is substituted for (or by) one not having a side chain, e.g., glycine, in this case, (e) by increasing the number of sites for sulfation and/or glycosylation. 15 161. For example, the replacement of one amino acid residue with another that is biologically and/or chemically similar is known to those skilled in the art as a conservative substitution. For example, a conservative substitution would be replacing one hydrophobic residue for another, or one polar residue for another. The substitutions include combinations such as, for example, Gly, Ala; Val, Ile, Leu; Asp, Glu; Asn, Gln; Ser, Thr; 20 Lys, Arg; and Phe, Tyr. Such conservatively substituted variations of each explicitly disclosed sequence are included within the mosaic polypeptides provided herein. 162. Substitutional or deletional mutagenesis can be employed to insert sites for N-glycosylation (Asn-X-Thr/Ser) or 0-glycosylation (Ser or Thr). Deletions of cysteine or other labile residues also may be desirable. Deletions or substitutions of potential 25 proteolysis sites, e.g. Arg, is accomplished for example by deleting one of the basic residues or substituting one by glutaminyl or histidyl residues. 163. Certain post-translational derivatizations are the result of the action of recombinant host cells on the expressed polypeptide. Glutaminyl and asparaginyl residues are frequently post-translationally deamidated to the corresponding glutamyl and asparyl 30 residues. Alternatively, these residues are deamidated under mildly acidic conditions. -53- WO 2006/074378 PCT/US2006/000474 Other post-translational modifications include hydroxylation of proline and lysine, phosphorylation of hydroxyl groups of seryl or threonyl residues, methylation of the o amino groups of lysine, arginine, and histidine side chains (T.E. Creighton, Proteins: Structure and Molecular Properties, W. H. Freeman & Co., San Francisco pp 79-86 5 [1983]), acetylation of the N-terminal amine and, in some instances, amidation of the C terminal carboxyl. 164. It is understood that one way to define the variants and derivatives of the disclosed proteins herein is through defining the variants and derivatives in terms of homology/identity to specific known sequences. For example, SEQ ID NO: 2 sets forth a 10 particular sequence of AR and SEQ ID NO:1 sets forth a particular sequence of an AR protein. Specifically disclosed are variants of these and other proteins herein disclosed which have at least, 70% or 75% or 80% or 85% or 90% or 95% homology to the stated sequence. Those of skill in the art readily understand how to determine the homology of two proteins. For example, the homology can be calculated after aligning the two 15 sequences so that the homology is at its highest level. 165. Another way of calculating homology can be performed by published algorithms. Optimal alignment of sequences for comparison may be conducted by the local homology algorithm of Smith and Waterman Adv. Appl. Math. 2: 482 (1981), by the homology alignment algorithm of Needleman and Wunsch, J. MoL Biol. 48: 443 (1970), 20 by the search for similarity method of Pearson and Lipman, Proc. Natl. Acad. Sci. U.S.A. 85: 2444 (1988), by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, WI), or by inspection. 166. The same types of homology can be obtained for nucleic acids by for 25 example the algorithms disclosed in Zuker, M. Science 244:48-52, 1989, Jaeger et al. Proc. Nati. Acad. Sci. USA 86:7706-7710, 1989, Jaeger et al. Methods Enzymol. 183:281-306, 1989 which are herein incorporated by reference for at least material related to nucleic acid alignment. 167. It is understood that the description of conservative mutations and homology 30 can be combined together in any combination, such as embodiments that have at least 70% homology to a particular sequence wherein the variants are conservative mutations. -54- WO 2006/074378 PCT/US2006/000474 168. As this specification discusses various proteins and protein sequences it is understood that the nucleic acids that can encode those protein sequences are also disclosed. This would include all degenerate sequences related to a specific protein sequence, i.e. all nucleic acids having a sequence that encodes one particular protein 5 sequence as well as all nucleic acids, including degenerate nucleic acids, encoding the disclosed variants and derivatives of the protein sequences. Thus, while each particular nucleic acid sequence may not be written out herein, it is understood that each and every sequence is in fact disclosed and described herein through the disclosed protein sequence. For example, one of the many nucleic acid sequences that can encode the protein sequence 10 set forth in SEQ ID NO:1 is set forth in SEQ ID NO:2. It is understood that for this mutation all of the nucleic acid sequences that encode this particular derivative of the AR are also disclosed. It is also understood that while no amino acid sequence indicates what particular DNA sequence encodes that protein within an organism, where particular variants of a disclosed protein are disclosed herein, the known nucleic acid sequences that 15 encodes that protein are herein disclosed and described. 6. Pharmaceutical carriers/Delivery of pharamceutical products 169. As described above, the compositions can also be administered in vivo in a pharmaceutically acceptable carrier. By "pharmaceutically acceptable" is meant a material that is not biologically or otherwise undesirable, i.e., the material may be administered to a 20 subject, along with the nucleic acid or vector, without causing any undesirable biological effects or interacting in a deleterious manner with any of the other components of the pharmaceutical composition in which it is contained. The carrier would naturally be selected to minimize any degradation of the active ingredient and to minimize any adverse side effects in the subject, as would be well known to one of skill in the art. 25 170. The compositions may be administered orally, parenterally (e.g., intravenously), by intramuscular injection, by intraperitoneal injection, transdermally, extracorporeally, topically or the like, although topical intranasal administration or administration by inhalant is typically preferred. As used herein, "topical intranasal administration" means delivery of the compositions into the nose and nasal passages 30 through one or both of the nares and can comprise delivery by a spraying mechanism or droplet mechanism, or through aerosolization of the nucleic acid or vector. The latter may be effective when a large number of animals is to be treated simultaneously. -55- WO 2006/074378 PCT/US2006/000474 Administration of the compositions by inhalant can be through the nose or mouth via delivery by a spraying or droplet mechanism. Delivery can also be directly to any area of the respiratory system (e.g., lungs) via intubation. The exact amount of the compositions required will vary from subject to subject, depending on the species, age, weight and 5 general condition of the subject, the severity of the allergic disorder being treated, the particular nucleic acid or vector used, its mode of administration and the like. Thus, it is not possible to specify an exact amount for every composition. However, an appropriate amount can be determined by one of ordinary skill in the art using only routine experimentation given the teachings herein. 10 171. Parenteral administration of the composition, if used, is generally characterized by injection. Injectables can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solution of suspension in liquid prior to injection, or as emulsions. A more recently revised approach for parenteral administration involves use of a slow release or sustained release system such that a 15 constant dosage is maintained. See, e.g., U.S. Patent No. 3,610,795, which is incorporated by reference herein. 172. The materials may be in solution, suspension (for example, incorporated into microparticles, liposomes, or cells). These may be targeted to a particular cell type via antibodies, receptors, or receptor ligands. The following references are examples of the 20 use of this technology to target specific proteins to tumor tissue (Senter, et al., Bioconjugate Chem., 2:447-451, (1991); Bagshawe, K.D., Br. J. Cancer, 60:275-281, (1989); Bagshawe, et al., Br. J. Cancer, 58:700-703, (1988); Senter, et al., Bioconjugate Chem., 4:3-9, (1993); Battelli, et al., Cancer Immunol. Immunother., 35:421-425, (1992); Pietersz and McKenzie, Inmmunolog. Reviews, 129:57-80, (1992); and Roffler, et al., 25 Biochem. Pharmacol, 42:2062-2065, (1991)). Vehicles such as "stealth" and other antibody conjugated liposomes (including lipid mediated drug targeting to colonic carcinoma), receptor mediated targeting of DNA through cell specific ligands, lymphocyte directed tumor targeting, and highly specific therapeutic retroviral targeting of murine glioma cells in vivo. The following references are examples of the use of this technology 30 to target specific proteins to tumor tissue (Hughes et al., Cancer Research, 49:6214-6220, (1989); and Litzinger and Huang, Biochimica et Biophysica Acta, 1104:179-187, (1992)). In general, receptors are involved in pathways of endocytosis, either constitutive or ligand -56- WO 2006/074378 PCT/US2006/000474 induced. These receptors cluster in clathrin-coated pits, enter the cell via clathrin-coated vesicles, pass through an acidified endosome in which the receptors are sorted, and then either recycle to the cell surface, become stored intracellularly, or are degraded in lysosomes. The internalization pathways serve a variety of functions, such as nutrient 5 uptake, removal of activated proteins, clearance of macromolecules, opportunistic entry of viruses and toxins, dissociation and degradation of ligand, and receptor-level regulation. Many receptors follow more than one intracellular pathway, depending on the cell type, receptor concentration, type of ligand, ligand valency, and ligand concentration. Molecular and cellular mechanisms of receptor-mediated endocytosis has been reviewed (Brown and 10 Greene, DNA and Cell Biology 10:6, 399-409 (1991)). a) Pharmaceutically Acceptable Carriers 173. The compositions, including antibodies, can be used therapeutically in combination with a pharmaceutically acceptable carrier. 174. Pharmaceutical carriers are known to those skilled in the art. These most 15 typically would be standard carriers for administration of drugs to humans, including solutions such as sterile water, saline, and buffered solutions at physiological pH. The compositions can be administered intramuscularly or subcutaneously. Other compounds will be administered according to standard procedures used by those skilled in the art. 175. Phannaceutical compositions may include carriers, thickeners, diluents, 20 buffers, preservatives, surface active agents and the like in addition to the molecule of choice. Pharmaceutical compositions may also include one or more active ingredients such as antimicrobial agents, antiinflammatory agents, anesthetics, and the like. 176. The pharmaceutical composition may be administered in a number of ways depending on whether local or systemic treatment is desired, and on the area to be treated. 25 Administration may be topically (including ophthalmically, vaginally, rectally, intranasally), orally, by inhalation, or parenterally, for example by intravenous drip, subcutaneous, intraperitoneal or intramuscular injection. The disclosed antibodies can be administered intravenously, intraperitoneally, intramuscularly, subcutaneously, intracavity, or transdennally. 30 177. Preparations for parenteral administration include sterile aqueous or non aqueous solutions, suspensions, and emulsions. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, and injectable -57-- WO 2006/074378 PCT/US2006/000474 organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. Parenteral vehicles include sodium chloride solution, Ringer's dextrose, dextrose and sodium chloride, lactated Ringer's, or fixed oils. Intravenous vehicles include fluid and nutrient 5 replenishers, electrolyte replenishers (such as those based on Ringer's dextrose), and the like. Preservatives and other additives may also be present such as, for example, antimicrobials, anti-oxidants, chelating agents, and inert gases and the like. 178. Formulations for topical administration may include ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional 10 pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable. 179. Compositions for oral administration include powders or granules, suspensions or solutions in water or non-aqueous media, capsules, sachets, or tablets. Thickeners, flavorings, diluents, emulsifiers, dispersing aids or binders may be desirable. 15 180. Some of the compositions may potentially be administered as a pharmaceutically acceptable acid- or base- addition salt, formed by reaction with inorganic acids such as hydrochloric acid, hydrobromic acid, perchloric acid, nitric acid, thiocyanic acid, sulfuric acid, and phosphoric acid, and organic acids such as formic acid, acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, malonic acid, succinic 20 acid, maleic acid, and fumaric acid, or by reaction with an inorganic base such as sodium hydroxide, ammonium hydroxide, potassium hydroxide, and organic bases such as mono-, di-, trialkyl and aryl amines and substituted ethanolamines. b) Therapeutic Uses 181. The dosage ranges for the administration of the compositions are those large 25 enough to produce the desired effect in which the symptoms disorder are effected. The dosage should not be so large as to cause adverse side effects, such as unwanted cross reactions, anaphylactic reactions, and the like. Generally, the dosage will vary with the age, condition, sex and extent of the disease in the patient and can be determined by one of skill in the art. The dosage can be adjusted by the individual physician in the event of any 30 counterindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. D. Methods of making the compositions -58- WO 2006/074378 PCT/US2006/000474 182. The compositions disclosed herein and the compositions necessary to perform the disclosed methods can be made using any method known to those of skill in the art for that particular reagent or compound unless otherwise specifically noted. 183. Disclosed are animals produced by the process of transfecting a cell within 5 the animal with any of the nucleic acid molecules disclosed herein. Disclosed are animals produced by the process of transfecting a cell within the animal any of the nucleic acid molecules disclosed herein, wherein the animal is a mammal. Also disclosed are animals produced by the process of transfecting a cell within the animal any of the nucleic acid molecules disclosed herein, wherein the mammal is mouse, rat, rabbit, cow, sheep, pig, or 10 primate. 184. Also disclosed are animals produced by the process of adding to the animal any of the cells disclosed herein. E. Examples 185. The following examples are put forth so as to provide those of ordinary skill 15 in the art with a complete disclosure and description of how the compounds, compositions, articles, devices and/or methods claimed herein are made and evaluated, and are intended to be purely exemplary of the invention and are not intended to limit the scope of what the inventors regard as their invention. Efforts have been made to ensure accuracy with respect to numbers (e.g., amounts, temperature, etc.), but some errors and deviations 20 should be accounted for. Unless indicated otherwise, parts are parts by weight, temperature is in *C or is at ambient temperature, and pressure is at or near atmospheric. 1. Example 1 a) Methods (1) Mice 25 186. All animal procedures were approved by the Animal Care and Use Committee of University of Rochester School of Medicine, in accordance with the NIH guidelines. Construction of targeting vectors and generation of the chimera founder mice have been described previously (Yeh,S, et al. (2002) Proc Natl Acad Sci USA 99:13498 13503 and United States Patent Application 10/484,950 and PCT application 30 PCT/US02/24234, all of which are incorporated herein at least for information related to making AR Knock Out (ARKO) mice). The strains of the mosaic founder mice were C57BL/6 and 129Sv background. p-Actin is a housekeeping gene and is universally -59- WO 2006/074378 PCT/US2006/000474 expressed in every tissue; therefore, the p-Actin promoter driven Cre (ACTB-Cre; Jackson Laboratories, Bar Harbor, ME) will express and delete floxed AR fragments in all the tissues. The AR-/y mice were genotyped by PCR, as described previously (Yeh,S, et al. (2002) Proc Natl Acad Sci USA 99:13498-13503). Animals were housed in pathogen free facilities, 5 maintained on a 12-hour light/dark schedule (light on at 0600) and had free access to standard laboratory chow (no. 5010; PMI Lab Diet, St. Louis, MO) and water. (2) Histology 187. Tissues were fixed in 10% neutral buffered formalin and imbedded in paraffin. Non-adjacent sections, separated by 70-80 tm, were obtained from perigonadal 10 fat pads and analyzed systematically with respect to adipocyte size and number. Staining of the sections was performed with hematoxylin/eosin. Images were acquired using an E800 microscope (Nikon, Melville, NY) and a SPOT camera (Diagnostic Instruments, Sterling Heights, MI) and were analyzed using SigmaScan Pro (version 5.0; SPSS Inc., Chicago, IL) software. 15 (3) Analytical Procedures 188. Fasting blood samples were taken from mice 14-h after withdrawal of food. Blood samples designated as random-fed state were drawn 6-h after introducing food into the cages of mice that had been subjected to a preceding 14-h fast. Blood glucose concentrations were measured using a glucometer (One Touch Ultra; Lifescan Inc., 20 Milpitas, CA). Insulin levels and leptin levels were determined in duplicate 5 ptl serum samples using a mouse insulin and leptin ELISA kit (Crystal Chem Inc., Downers Grove, IL) according to the manufacturer's protocol. Serum tumor necrosis factor-alpha (TNF-a) levels were determined in duplicate in 20 [l serum samples using a mouse TNF-a ELISA kit (eBioscience, San Diego, CA) according to the manufacturer's protocol. For the glucose 25 tolerance test (GTT), after a 14-h fast, mice were given an oral bolus of D-glucose (2 g/kg body weight) and the blood glucose concentration was measured in samples taken at 0, 30, 60, 90, and 120 min after the glucose bolus. An Insulin tolerance test (ITT) was performed on 6-h fasting mice by intraperitoneal injection of 1 U/kg body weight human insulin (Sigma-Aldrich, St. Louis, MO). Blood glucose concentration was determined at 0, 30, 60, 30 90, and 120 min after insulin administration. Triglyceride (TG) levels in serum from fasting animals were determined using the GPO-Trinder Assay (Sigma-Aldrich). Serum free fatty acid (FFA) levels in fasting animals were measured using NEFA-Kit-U (Wako -60- WO 2006/074378 PCT/US2006/000474 Pure Chemical USA Inc., Richmond, VA). For determination of tissue TG content, 50-100 mg tissue pieces were homogenized on ice in pH 7.3 extraction buffer (20 mM Tris, 1 mM p-mercaptoethanol, 1 mM EDTA). Following centrifugation, the glycerol content of the supernatants was determined using the GPO-Trinder assay (Sigma-Aldrich) according to 5 the manufacturer's instructions. (4) Phosphoinositide-3-OH kinase (P13K) activity. 189. Mice were subjected to 14-h fast, injected intraperitonelly with saline or insulin (10 U per kg (body weight)) and sacrificed 3 min after injection. Tissues were collected and frozen. P13K activity was measured in phosphotyrosine immunoprecipitates 10 (p-Tyr, Ab-4; EMD Biosciences, Inc., San Diego, CA) from white adipose tissue (WAT), skeletal muscle, and liver lysates as previously described (Goodyear,LJ, et al. (1995) J Clin Invest 95:2195-2204). (5) Cell Culture, Transient Transfections, and Reporter Gene Assays 15 190. The human prostate cancer cell lines, LNCaP, PC-3, and DU145, were maintained in Dulbecco's minimum essential medium (DMEM) containing 5% fetal calf serum (FCS). Transfections using the calcium phosphate precipitation method and chloramphenicol acetyltransferase (CAT) and luciferase (Luc) assays were performed as previously described (Miyamoto et al. (1998) Proc. Natl. Acad. Sci. U.S.A. 95, 7379-7384; 20 Yeh et al. (1999) Endocrine 11, 195-202; Miyamoto et al. (1998) Proc. Natl. Acad. Sci. U.S.A. 95, 11083-11088). Briefly, 1-4 x 105 cells were plated on 35-mm or 60-mm dishes 24 h before adding the precipitation mix containing a CAT or Luc reporter gene and a # galactosidase expression plasmid (pCMV- # -gal) as an internal control for normalization of transfection efficiency. The medium was changed to phenol-red-free DMEM with 5% 25 charcoal-stripped FCS 1 h before transfection. In each experiment, the total amount of transfected DNA per dish was maintained as a constant by addition of empty expression vector (pSG5 or pVP16, as appropriate). The medium was changed again 24 h after transfection, and the cells were treated with 1 nM of DHT or 1 pM of HF for 24 h. The cells were then harvested and whole cell extracts were used for CAT or Luc assay. The 30 CAT activity was quantitated with a Phosphorhmager (Molecular Dynamics). The Luc assay was determined using a Dual-Luciferase Reporter Assay System (Promega) and luminometer. -61- WO 2006/074378 PCT/US2006/000474 (6) Glutathione S-transferase (GST) pull-down assay 191. GST-AR, Rb, ARA54, ARA55, ARA24, ARA70, ARA267, Gelsolin, Supervillin, and SRC-1 fusion proteins and GST control protein were purified as described by the manufacturer (Amersham Pharmacia). The purified GST proteins were then 5 resuspended in 100 pl of interaction buffer (20 mM HEPES/pH 7.9, 150 mM KCl, 5 mM MgC1 2 , 0.5 mM EDTA, 0.5 mM Dithiothreitol, 0.1% (v/v) NP-40, 0.1% (w/v) BSA and 1 mM PMSF) and mixed with 5 pl of [ 35 S]-labeled TNT AR protein in the presence or absence of 1 pM ligand at 4oC for 3 hours. After several washes with NETN buffer, the bound proteins were separated by SDS/8% PAGE and visualized using autoradiography. 10 (7) Western Blot 192. Western blotting analysis was performed in the stable LNCaP cells, using NH27 polyclonal antibody for the AR and monoclonal prostate-specific antigen (PSA) antibody (DAKO), as described previously (Miyamoto et al. (1998) Proc. Nati. Acad. Sci. US.A. 95, 7379-7384). An antibody for P-actin (Santa Cruz Biotechnology) was 15 used as the internal control. (8) Mammalian Two-Hybrid Assay 193. DU145 cells were transiently cotransfected with a GAL4-hybrid expression plasmid, a VP 16-hybrid expression plasmid, the reporter plasmid pG5-CAT, and the pCMV-p-gal internal control plasmid. Transfections and CAT assays were 20 performed as described above. (9) Intraperitoneal leptin administration 194. Mice were divided into 2 groups and were treated once daily with equal volumes of intraperitoneal injections of saline or mouse leptin (R&D Systems Inc., Minneapolis, MN) dissolved in saline at 5 pg/g (body weight) doses for 6 days. Food 25 intake and changes in body weight were measured to estimate the effects of exogenous leptin administration. (10) Establishment of wild type (WT) and AR-/y mouse embryonic fibroblast (MEF) cell lines 195. MEF cell lines were self-immortalized following the 3T9 protocol. Briefly, 30 primary WT and AR-/y MEFs were isolated from E12.5 littermate embryos and cultured in DMEM plus 10% (v/v) FBS. Early passage (less than 5) MEFs were then plated at a density of 2.5 x 106 cells per 25 ml flask. Every 3 days, cells were gently trypsinized and -62- WO 2006/074378 PCT/US2006/000474 re-plated at the same density. Cells were immortalized after 5 months of continuous culture. 196. Cell culture and Oil-Red 0 staining. Mouse 3T3-L1 preadipocytes (CL173; ATCC, Manassas, VA), WT, and AR-/y MEF cell lines were maintained in DMEM 5 containing 10% (v/v) FBS. For differentiation, the medium was changed to DMEM supplemented with 10% (v/v) FBS, 10 ptg/ml insulin, 0.5 mM 3-isobutyl-1-methylxanthine, and 1 AM dexamethasone at 2 days after reaching confluence and then incubated with 10 nM DHT or 100 nM DHT and with or without hydroxyflutamide (HF). The media containing either of the drugs were renewed every other day. Nine days after stimulation 10 and incubation with these drugs, cells were fixed with 10% formaldehyde for 1-h and then with 0.1 mg/ml Oil-Red 0 solution for 2-h at room temperature. All liquid in each well was removed and 100 y1 of isopropyl alcohol was added to dissolve the precipitation. The OD at 510 nm was determined by ELISA spectrometry. (11) Real-time quantitative RT-PCR 15 197. Mouse WATs, skeletal muscles, and livers from WT and AR'S were dissected and total RNA isolated by using a TRIzol reagent (Invitrogen Corp., Carlsbad, CA). cDNA synthesis and PCR were performed using SuperscriptTM RNase H- Reverse Transcriptase and cDNA cycle kit (Invitrogen Corp.) according to the manufacturer's instructions. Real-time PCR was performed using icycler real-time PCR amplifier (Bio 20 Rad Laboratories, Hercules, CA). Each PCR reaction contained 1 Al cDNA, 50 yM primers and 12.5 pl iQTM SYBR green supermix reagent (Bio-Rad Laboratories) and was triplicated. 18s was used as an internal control. A list of the primer sequences for real-time PCR is available in Table 3.

All values are presented as mean SE. Differences between two groups were assessed using unpaired two-tailed Student's t-test or among more than two groups by 5 ANOVA. In all Statistical comparisons, P < 0.05 was defined as a significant difference. SigmaStat statistics software (version 2.0; SPSS Inc.) was used for all calculations. (13) DHT replacement study 199. A 60-day time-release 5a-DHT (5 mg) and placebo pellet (Innovative Research of American, Sarasota, FL), inserted into a subcutaneous pocket (posterior neck 10 region) of male WT and AR'S mice, respectively. Eight weeks after implantation of the pellet, the mice were sacrificed to study serum hormones and metabolic parameters. b) Results (1) Loss of AR is associated with fat accumulation and altered metabolic profiles. 15 200. Using Cre/loxP-mediated recombination by crossing AR-loxP mice with ACTB-Cre mice, mice lacking AR in mixed C57BL/6/129Sv/FVB background were generated (Yeh,S, et al. (2002) Proc NatlAcad Sci U.S.A. 99:13498-13503). Male WT and knockout AR-/y mice were used for the present studies. Since the AR-/y mice were phenotypically female in appearance, female WT mice were also used as an additional 20 comparison group for phenotypic analysis. The growth curves of male WT, female WT, and AR-/y mice showed that AR-/y mice exhibited a significant decrease in the body weight gain throughout the 20th week as compared to male WT mice (Fig. IA). The body weight of male WT and AR-/y mice was significantly greater at all timepoints after 8 weeks as compared to female WT littermates. However, body weight gain was significantly greater in AR-/y mice 25 after 22 weeks as compared to their male WT and female WT littermates throughout the 40 week study period (male WT: 36.0 ± 1.3 g; female WT: 26.35 ± 0.59 g; AR-/y: 40.87 + 1.0 g; P = 0.009 for male WT versus AR-/y; n = 9). This was accompanied by significantly enlarged gonadal and perirenal fat pads compared with male WT and female WT counterparts (Fig. 1 B, C, and Table 4). -64- WO 2006/074378 PCT/US2006/000474 TABLE 4 Physiological and metabolic parameters of 35-week-old study groups Genotype Male WT Female WT AR-' n 9 10 9 Body weight (g) 33.15+1.2 25.81 ± 0.44 39.06 2.7* Gonadal fat/body (%) 2.21 0.14 0.34 ± 0.08 3.29 ± 0.23 * Serum TG (mmol/1) 0.30 ± 0.04 0.32± 0.08 0.67 + 0.1 t Serum NEFA (mEq/1) 0.25 0.02 0.25 ± 0.02 0.71 ± 0.04 $ Serum cholesterol (mmol/1) 2.28 0.05 2.28 ± 0.06 2.44 0.05 Fasting blood glucose (mmol/1) 6.46 ± 0.31 6.41 ± 0.27 7.94 ± 0.38 * Fed blood glucose (mmol/1) 14.03 ± 0.54 14.93 ± 0.29 19.75 ± 0.78 $ Fasting serum insulin (ng/ml) 0.55 + 0.13 0.53 ± 0.33 0.88 0.33 * Fed serum insulin (ng/ml) 0.92 ± 0.17 1.12 ± 0.14 1.54 0.16 * Values are mean ± SE.

Aging obesity profiles are consistent with previous findings (Matsumoto,T, et al. (2003) J.SteroidBiochen.Mol.Biol. 85:95-99; Sato,T, et al. (2003) Biochem. Biophys. 5 Res. Commun. 300:167-171). Circulating TG levels of AR-/y mice was increased by 2 fold as compared to male WT and female WT mice (Table 3). Notably, histological analysis of WATs after fixation (Fig. IB) and quantification of adipocyte size (Fig. IC) revealed that adipocytes from 35-week-old AR-/y mice were significantly larger than those in WT counterparts. The comparison data for muscle mass and bone mass showed no significant 10 difference in those tissue masses between WT and AR-/y mice. Although obvious enlargement of adipose tissues can be seen from intra-abdominal appearance in AR-/y mice, this only accounts for ~15% increased body weight in AR-/y mice as compared to WT mice. These results indicate that AR-/y mice had marked increased adiposity at an older age. -65- WO 2006/074378 PCT/US2006/000474 (2) Development of insulin resistance in AR~S mice. 202. Given the excess lipid deposition in WAT, blood glucose and insulin levels were examined in male WT, female WT, and ARy mice. AR~Y mice start to show elevated blood glucose at 20 weeks, which persisted to at least 35 weeks under both the fasting and 5 fed conditions (Table 4). The hyperglycemia occurred despite a marked increase in serum insulin levels in the fasting (~60%) and fed (-67%) states. (Table 4), indicating that AC mice were more resistant to insulin than their WT counterparts under ambient conditions. 203. To assess whole-body glucose homeostasis, oral bolus GTT and intraperitoneal ITT were performed on these mice. Oral bolus GTT demonstrated marked 10 glucose intolerance and distinguishable AUC in AR'S mice (Fig. 2A and B). Blood glucose levels of AR-'y mice were greater at all times during the test and hyperglycemia was still apparent 2-h after the glucose bolus. ITT showed that AR~S mice were slightly resistant and highly resistant to the hypoglycemic effect of exogenous insulin at both 25- and 35-week old, respectively (Fig. 2C and D). The defect in whole-body insulin sensitivity was not due 15 to female-like phenotype in AR- mice, because no differences were detected in the response patterns of male WT and female WT mice. 204. As insulin resistance can be correlated to the activity of P13K, a signaling mediator that is needed for many metabolic effects of insulin, insulin-stimulated P13K activity was examined using WT mice as controls. The P13K activity upon insulin 20 stimulation in AR~l mice was reduced by 60-63% in insulin target organs, such as skeletal muscle and liver (Fig. 2E), suggesting that AR~J mice did have skeletal muscle and hepatic insulin resistance and hyperinsulinemia with obesity. (3) Increased lipid deposition and leptin levels in AR~y mice. 25 205. Serum FFA levels in the fasting state are elevated in AR'Y mice (Table 4). Moreover, the skeletal muscle and hepatic TG contents markedly increased by 2.6 fold and 1.9 fold, respectively, indicating that insulin resistance was associated with increasing TG deposition in the skeletal muscle and liver (Fig. 2F). 206. Also observed was that from the increased WAT mass, fed serum leptin 30 concentrations were higher in AR~5 mice at both 25- and 35-week-old (Fig. 3A). Moreover, serum leptin levels show elevated linear relationships with body weight in AR~Y mice as compared with WT littermates (Fig. 3B). Surprisingly, fed serum leptin levels were also -66- WO 2006/074378 PCT/US2006/000474 higher despite the tact that AR-' mice gained significantly less weight before 20-week-old (Fig. 3A), indicating loss of AR can cause increased leptin earlier than increased body weight. Adiponectin, an insulin-sensitizing adipokine, was reduced in AR'S mice (Fig. 3C), whereas TNF-ax was no difference (Fig. 3D). 5 (4) Development of leptin resistance in AR' mice. 207. It was also found that food intake and body weight was significantly reduced following an exogenously administrated leptin in WT mice, but not in AR4Y mice (Fig. 4, A and B). Furthermore, food intake was not significantly different in AIC mice as compared with that in WT mice before exogenous leptin administration despite elevated leptin levels, 10 indicating AR4Y mice were leptin resistant at 35-week-old. However, the food intake and body weight were reduced following an exogenous load of leptin in both 20-week-old AK / mice and WT mice, whereas two study groups have similar body weight and adiposity (Fig. 4, C and D). These results indicate that AR' mice develop leptin resistance that can be due to development of adiposity and long-term absence of AR. 15 (5) Loss of AR altered the lipid metabolic profiles. 208. To determine the mechanism of the increased lipid deposition in WAT, as well as skeletal muscle and hepatic TG accumulation, mRNA from these tissues were further analyzed. The mRNA levels of four lipid metabolism genes, peroxisome proliferators-activated receptor gamma (PPARy), CCAAT/enhancer-binding protein alpha 20 (C/EBPca), adipocyte fatty acid binding protein/adipocyte P2 (aP2), and sterol regulatory element-binding protein 1c (SREBPlc), were higher in WAT of AR as compared to WT mice (Table 5), indicating loss of AR can contribute to the increase of adipogenesis and lipogenesis via stimulation of several genes, such as lipid metabolism genes. -67- WO 2006/074378 PCT/US2006/000474 TABLE 5 Expression of lipid metabolism genes in WAT, liver, and skeletal muscle in ARU mice as quantified by real-time RT-PCR Gene AACT (Avg.

These 5 results indicate that AR is directly or indirectly involved in lipid metabolism. (6) DHT replacement failed to reverse the metabolic abnormalities and insulin resistance in AR~e mice 209. As serum T levels were markedly decreased due to atrophic testes in AR-' mice, it was impossible to exclude the possibility that the insulin resistance and metabolic 10 abnormalities in AR~Y mice simply reflected the low levels of androgens. To address this issue, nonaromatizable androgen DHT was given to AR~5 and WT littermates to both 26 week-old mice and 12-week-old mice. Several serum hormones and metabolic parameters were assessed after 8 weeks of pellet implantation. DHT replacement restored serum DHT levels to within the physiological range (0.6-0.9 ng/ml) in AR~Y mice. It is known that 15 estradiol is converted not only from estrone but also T, therefore it was also impossible to exclude another possibility that the abnormalities in AR-Y mice simply reflected less estrogen converted from T, but it was found that serum estradiol levels, as well as levels of the prohormone androstenedione remained unchanged in AR- mice compared to WT mice -68- WO 2006/074378 PCT/US2006/000474 (Table 6 and Table 7). DHT replacement couldn't reverse the metabolic abnormalities and insulin resistance in AIR7' mice in both age study groups (Table 6 and Table 7), which indicates that androgen actions directly mediated via AR are significant in insulin sensitivity. Exogenous DHT replacement fails to reverse the metabolic abnormalities and 5 insulin resistance in AR'y mice. Ct> C', 0 - t CtO U) 6-0 0a0 ~t', 00 00 CDt 00 C) ON c.,

(1996) J.Clin.Endocrinol.Metab 81:3697-3701). The results disclosed herein demonstrate that mice lacking AR develop insulin and leptin resistance at an advanced age. Late onset of obesity, as observed in AR-/y mice, was reported to be 5 associated with insulin resistance (KubotaN, et al. (1999) Mol Cell 4:597-609). The marked hyperinsulinemia and hyperglycemia in AR~C mice clearly demonstrate that loss of AR can reduce insulin sensitivity. A relatively small increase in body weight (~15%) is associated with a remarkable reduction in insulin sensitivity (-65%) in AR-Y mice, and insulin resistance that occurs as early as 20 weeks of age in non-obese AR- mice, 10 indicating that loss of AR can directly reduce insulin sensitivity in target tissues without first increasing body weight significantly. 211. The phenotypically female appearance of AR~0 mice is similar to that of testicular feminized (Tfn) mice in which AR is functionally deficient by introduction of the Tfm mutation in the AR gene (He,WW, et al. (1991) Nucleic Acids Res. 19:2373 15 2378). To this regard, female WT mice were added for comparison, and these mice remain smaller and have less adiposity than both male WT and AR-/y mice. In addition, no significantly distinguishable metabolic pattern was found between female WT and male WT mice, whereas AR-/y mice exhibited severe insulin resistance and obesity. A previous study has showed that db/db Tfin/Y males develop severe diabetes. In contrast, female 20 db/db littermates only exhibit mild hyperglycemia (Prochazka,M, and Leiter,EH. (1991) Horm.Metab Res. 23:149-154). 212. The excess fat mass in AR~Y mice can be due to an impaired ability of skeletal muscle to use lipid as fuel substrate and of liver to catabolize lipid, leading to a shunting of lipid to adipose tissue. In fact, the unchanged food intake in AR' mice 25 indicates that the excess weight gain and adiposity can be due to normal energy input coupled with reduced lipid oxidation and increased lipid storage. Indeed, impairment in hepatic lipid oxidation resulted in elevated circulating FFA, and hepatic steotosis in PPARa-null mice (Kersten,S, et al. (1999) J.Clin.Invest 103:1489-1498). Activation of PPARa by fibrates reduces adiposity in fa/fa Zucker diabetic fatty (ZDF) rats by the 30 activation of several peroxisomal and mitochondrial fatty acid oxidation genes (Guerre Millo,M, et al. (2003) J.Biol.Chem. 275:16638-16642). Given that skeletal muscle and liver are the major sites of lipid oxidation and deposition, respectively, it is possible that -71- WO 2006/074378 PCT/US2006/000474 loss of PPARa could produce such an effect. Consistent with this possibility, the decreased PPARa expression in skeletal muscle, decreased hepatic lipid metabolism, and the subsequent alterations in expression of genes that stimulate adipocyte differentiation (PPARy (KubotaN, et al. (1999) Mol Cell 4:597-609), C/EBPa (Loftus,TM, et al. (1997) 5 Curr.Opin.Genet.Dev. 7:603-608), and SREBPlc (Kim,JB, et al. (1998) J.Clin.Invest 101:1-9)) and lipid accumulation (aP2 (Hotamisligil,GS, et al. (1996) Science 274:1377 1379)) in WAT were found in AR-/y mice. Furthermore, liver-specific AR knockout mice, which are more susceptible to high-fat diet (HFD) -induced insulin resistance, showed lower hepatic PPARa expression. Recent studies using hyperinsulinemic-euglycemic 10 clamp have shown that PPARc-null mice are not protected against HFD-induced insulin resistance (Haluzik,M, et al. (2004) Endocrinology 145:1662-1667). Thus, loss of PPARa expression in AR 4 Y mice can be a mechanism contributing to the decreased insulin sensitivity observed. 213. Also skeletal muscle and hepatic insulin resistance in ARy mice can be 15 secondary to altered release of adipokine. Leptin increased insulin sensitivity and concomitantly reduced TG content by promoting lipid oxidation in animal models of insulin resistance and in humans with lipodystrophic diabetes (Petersen,KF, et al. (2002) J. ClinInvest 109:1345-1350). The AR-/y mice with elevated leptin, however, have significant leptin resistance when exogenous leptin is administered. Related results have 20 been observed in ZDF rats, ob/ob mice that lack leptin, and db/db mice that have an inactive leptin receptor, and the livers of such mice are all steatotic (Lee,Y, et al. (2001) J.Biol. Chem. 276:5629-5635; Shimomura,I, et al. (1999) J.Biol. Chem. 274:30028-30032). In ZDF rats, the skeletal muscle, pancreas, and heart are also steatotic (Flier,JS. (1997) Proc.Natl.Acad.Sci. U.S.A 94:4242-4245). A strong correlation between intracellular TG 25 content and insulin resistance has been established in both human and animal studies of obesity-related insulin resistance and type 2 diabetes (Unger,RH, and Orci,L. (2001) FASEB J. 15:312-321). Consistent with this possibility, a substantial ectopic deposition of TG in nonadipocytes such as skeletal muscle and liver in AR-/y mice is a central element. TG overload of nonadipocytes cause, respectively, insulin resistance, lipotoxic heart 30 disease and adipogenic type 2 diabetes (Unger,RH, and Orci,L. (2000) Int.JObes.Relat Metab Disord. 24 Suppl 4:S28-S32). It was also demonstrated, through P13K activity assay following injection of insulin, that skeletal muscle and liver in AR-/y mice are insulin -72- WO 2006/074378 PCT/US2006/000474 resistant. Interestingly, PPARa is necessary for the lipopenic action of hyperleptinemia on white adipose and liver tissues. In PPARa-null mice infused with adenovirus-leptin, up regulation of carnitine palmitoyl transferase-1 mRNA in fat, down-regulation of acetyl CoA carboxylase in liver, and up-regulation of PPARy coactivator-1 alpha mRNA in both 5 tissues are abolished, as is the reduction in their TG content, indicating that leptin action may be mediated through PPARa (Lee,Y, et al. (2002) Proc.Natl.Acad.Sci. U.S.A 99:11848-11853). Thus, loss of PPARa in AR-/y mice can reduce leptin action despite elevated leptin levels. In contrast, decreased adiponectin and no elevation of serum TNF-a (another adipokine that contributes to insulin resistance) (Hotamisligil,GS. (1999) JIntern 10 Med 245:621-625) was found in AR-/y mice at 35-week-old, whereas mice lacking adiponectin exhibited severe insulin resistance (Yamauchi,T, et al. (2001) Nat.Med. 7:941 946). However, it is known that other adipokines also mediate the metabolism of lipids and contribute to the pathogenesis of insulin resistance. 214. Indirect interactions of AR and PPARa through nuclear receptor coregulators 15 are possible. ARA70, a coactivator of the AR, was able to physically interact with PPARa as determined by coimmunoprecipitation. In the adrenal cell line Y1, ARA70 behaved as a repressor of PPARa (Heinlein,CA, and Chang,C. (2003) Endocrine. 21:139-146). An early study indicated that in primary rat adipocytes expressing AR, testosterone and DHT were able to suppress leptin mRNA and leptin secretion (Machinal,F, et al. (1999) 20 Endocrinology 140:1567-1574), suggesting a direct effect of testosterone on the regulation of leptin secretion in adipocytes. Additionally, using 3T3-L1 cells, it was demonstrated that DHT inhibited the adipogenesis of preadipocytes in vitro. This indicates that a direct effect of AR also exists at the level of adipogenesis in adipocytes. 215. Taken together, these data indicate that loss of AR can contribute to an 25 increase of leptin levels and leptin resistance, which can play important roles for the development of obesity and insulin resistance. A previous study using transgenic mice overexpressing leptin demonstrated that loss of the leptin effectiveness in older transgenic mice might contribute to the accumulation of adipose mass (Qiu,J, et al. (2001) Endocrinology 142:348-358). Consistent with this possibility, the AR-/y mice were 30 progressively desensitized to leptin due to long-term elevated circulating leptin throughout the 40-week study period. In rats, testosterone was reported to be associated negatively with serum leptin, independent of body mass index (Li,H, et al. (1997) Diabetes 46:2035 -73 - WO 2006/074378 PCT/US2006/000474 2039). Leptin levels are higher in aging men with lower testosterone (Luukkaa,V, et al. (1998) J. Clin.Endocrinol.Metab 83:3243-3246). Furthermore, low testosterone may lead to the accumulation of visceral fat (Cohen,PG. (2001) Med Hypotheses 56:702-708). As total body fat mass increases, resistance develops to both leptin and insulin. Elevated leptin fails 5 to stimulate weight loss and the hypogonadal-obesity cycle ensures further visceral obesity and insulin resistance. In the present study, AR-/y mice progressively develop leptin resistance and insulin resistance, resulting in obesity. This differs from the ob/ob and db/db mice that display early onset genetic obesity and have leptin inactivity from a very early stage (Tschop,M, and Heiman,ML. (2001) Exp. Clin. Endocrinol. Diabetes. 109:307-319). 10 AR-/y mice have milder obesity due to the late onset of leptin and insulin resistance. However, leptin resistance in AR-/y mice that is similar with db/db mice, whereas dysfunctional leptin receptor is likely to be a major factor. Progressive insulin resistance can then lead to type 2 diabetes and other diseases, such as high TG-low high density lipoprotein pattern dyslipidemia, and the metabolic syndrome X, as well as increased risk 15 of cardiovascular diseases (Cohen,PG. (2001) Med Hypotheses 56:702-708). It has been reported that hypotestosteronemia may be a risk factor for coronary artery diseases in men (Phillips,GB, et al. (1994) Arterioscler Thronb 14:701-706). 216. Interestingly, not only lacking AR results in a metabolic syndrome, but both estrogen receptor alpha absence (Heine,PA, et al. (2000) Proc.Nat.Acad.Sci. U.S.A 20 97:12729-12734) and aromatase deficiency which loss of the ability to synthesis estrogen (Jones,ME, et al. (2000) Proc.Natl.Acad.Sci. U.S.A 97:12735-12740) result in a metabolic syndrome. These observations indicate a possibility that loss of both androgen and estrogen responsiveness disrupt energy homeostasis. 217. ARe mice not only have an AR deficiency but also have decreased serum 25 levels of androgens. In this regard, in AR4Y mice, treatment with nonaromatizable DHT restored the physiological serum DHT levels, whereas estrogen levels remained unchanged as compared to WT mice. Thus, the possibility of lacking estrogen receptor alpha (ERa) activation resulting in increased WATs, as seen in male mice deficient in either ERa or aromatase, can be excluded. Importantly, no reversed effect was found after DHT 30 treatment, indicating that insulin resistance in AR'l mice, disclosed herein, is mediated directly via AR. -74- WO 2006/074378 PCT/US2006/000474 218. In summary, AR mice provide an in vivo model showing that loss of AR increases serum leptin concentration and skeletal muscle/hepatic TG content, which can result in the development of obesity, leptin resistance, and insulin resistance. As obesity and progressive insulin resistance can lead to type 2 diabetes and an increased risk of 5 cardiovascular diseases (Fernandez-Real,JM, and Ricart,W (2003) Endocr Rev 24:278 301), a better understanding of the molecular mechanisms involved, and dissection of the roles of A-AR in insulin and leptin resistance can help in the development of better therapeutic approaches to type 2 diabetes, obesity, and other cardiovascular diseases. 2. Example 2: Dysregulation of Lipid Metabolism and Insulin 10 Signaling Accelerates Diet-Induced Hepatic Steatosis and Insulin Resistance in Mice Lacking Hepatic Androgen Receptor 219. In order to investigate the role of hepatic androgen receptor (AR) in the pathogenesis of hepatic steatosis and insulin resistance, hepatic AR knockout (AR(UIY)) mice were generated by crossbreeding floxAR mice with albumin-Cre mice. The AR / 15 mice showed similar growth curve to wild-type mice (Figure lA-B. Whole-body insulin action in awake AR(U/Y) and wild-type (wt) mice fed a high-fat diet (HFD) for 8 weeks was examined. In contrast to high-fat-fed wt mice, AR(L/Y) mice exhibit greater cumulative weight gain and increased serum glucose levels while being fed on a HFD for 24, 36, and 52 weeks (Figure 5C-F). AR(L .Y) mice were also marked by increase fat vacuoles in the 20 liver (Figure 6). Additionally, compared with WT mice, AR Y mice on a HFD displayed more hepatic steatosis, and a type 2 diabetes phenotype, characterized by hypertriglyceridemia, hyperinsulinemia, hyperglycemia, and insulin resistance possibly due to a decreased insulin-mediated P13K activation (Figure 7, Figure 8, and Table 8). -75 - WO 2006/074378 PCT/US2006/000474 Table 8.

IR index was calculated the product of the area of glucose and insulin x 102 220. The mRNA levels of the gluconeogenic enzymes, phosphoenolpyruvate carboxykinase, and hepatic nuclear factor-4 alpha were upregulated in livers of AR 'Y 5 mice as compared with wt mice fed with high-fat diet. Loss of hepatic AR increased sterol regulatory element-binding protein-ic, a key regulator of lipogenic gene transcription, and its downstream target mRNAs, as well as increased hepatic lipid accumulation. Loss of hepatic AR was also associated with a decrease in peroxisomal proliferator-activated receptor alpha mRNA expression, and a trend toward decreased fatty acid -oxidation. 10 221. Together, these data indicate that AR in liver plays an important role in pathogenesis of the metabolic syndrome by concordantly modulating lipid metabolism and insulin signaling. AR serves as a novel target for treatment of hepatic steatosis and hepatic insulin resistance. -76- WO 2006/074378 PCT/US2006/000474 F.
