Description

TISSUE PROTECTIVE PEPTIDES AND PEPTIDE ANALOGS FOR PREVENTING AND TREATING DISEASES AND DISORDERS ASSOCIATED WITH TISSUE DAMAGE The entire disclosure in the complete specification of our Australian patent application 2009206748 is by this cross-reference incorporated into the previous speeiication 1. INTRODUCTION The invention provides tissue protective peptides and peptide analogs for preventing or treating a disease or disorder associated with tissue damage and/or damage, an effect, or a symptom thereof including, but not limited to, caner, inflanuation, and exposure to a toxic agent. In particular, the invention provides tissue protective peptides and peptide analogs that share consensus sequences with fragments of Type I cytokine receptor ligands that have little or no potentially undesirable hematopoietic effects of the ful length ligands These peptides also include fragments, chimeras, as well as peptides designed to aimi the spatial localization of key amino acid residues within the tissue protective receptor ligands, eg, EPO. This invention further provides methods and uses of these peptides to modulate a subject's response and/or a symptom resulting from a disease or disorder associated with tissue damage for the purposes of treating, preventing or ameliorating the disease or disorder. Additionaly, the present invention provides pharmaceutical compositions comprising a peptide and a pharmaceutical acceptable carter, excipient or diluent for the treatment of a disease or disArder associated with tissue damage or damage, an effect or a symptom thereof, including, but not limited to, cancer, inflammation and exposure to a toxic agent in a subject in need thereof. 2. BACKGROUND OF THE iNVENTiON. Tissue damage can be caused by a substantive loss of tissue due to ischemic, traumatic, toxic, or inflammatory injuries in which ells within the tissue are destroyed by apoptosis or necrosis. Tissue damage can occur in a number of acute and chronic diseases and conditions. The degree to which tissue damage occurs is mediated by many factors, including

I

the type of disease or injury, the level of or severity of inflammation or trauma associated with the disease or injury, the location of the tissue damage, and the vascular sufficiency of the tissue. Recent evidence suggests that erythropoietin (EPO), a member of the TypeI cytokine family, commonly associated with the maintenance of hernatocrit may also play an important role in attenuating tissue damage through the interaction with its receptor, EPOR (Brines et al., 2004, Proc. Natl Acad Si. USA, 101(41):14907-12). Although it is hypothesized that EPO may provide compensatory responses that serve to improve hypoxic cellular environment and modulate programmed cell death caused by metabolic stress, the underlying molecular mechanism is yet to be clearly understood. Based upon this observation, investigators have explored the use of EPO in various indications, As an example, investigators have explored the use of EPO as a potential treatment for cancers based upon the observation that EPO used to treat anemia in oncology patients not only rectified the anemia but resulted in an enhancement of the well-being of the oncology patient as well (See U.S. Patent No. 6,579,525 and Blau C.A., 2007, Stem Cells 25(8):2094-7). U.S. Patent No. 6,579,525 to Haran-Ghera et al. relates to the use of recombinant EPO for the treatment of multiple myelomas and hypthesizes that EPO induces an immune response to the tumor. Additionally, U.S. Patent Application No. 11/093,177, publication no. US 2005/0267027, discloses the use of EPO to inhibit angiogenesis in tumors by reducing HIl-Ia and/or VEGF expression in the tumors. However, EPO as a potential tissue protective agent suffers from serious disadvantages due to its erythropoietic effect In particular with chronic dosing, such as would be envisioned in indications such as cancer and inflammation, the frequent applications of therapeutic doses of EPO may significantly increase a subject's hematocrit, which may lead to hypertension, seizures, and vascular thrombosis. Further, with regard to cancer, the potential of EPO as a therapeutic has not been realized. It has been determined that several types of cancer, such as breast cancers, express, and tend to over-express, erythropoietin receptors This has led to concerns that the therapeutic use of EPO to treat cancer would lead to further growth of the tumor as opposed to a regression of the turnor's development (see Blau, 2007, supra, and U.S. Patent Application No. 10/432,899, published as US 2005/0260580) This concern has been borne out in the clinic as several trials of EPO within various cancer indications have been halted due to an increase in mortality due to tumor growth (Blau), In light of these adverse clinical outcomes the FDA has attached a Black 2 Box warning on approved EPO products cautioning against their use in unapproved cancer indications. Additionally, mature human EPO protein is a 165 amino acid protein having a molecular weight of about 30.4 kDa measured by mass spectroscopy. The recombinant protein can be produced in Chinese hamster ovary cells in an expensive and labor intensive process that is highly regulated. Further, EPO must be stored under stringent conditions to maintain its activity. Given these limitations EPO is not an ideal candidate to address public emergencies, such as the release of a toxic agent such as radiation or a chemical agent, either through an industrial accident or act of terrorism or war that would require the rapid mass production of the therapeutic for wide distribution. Accordingly, there is a need for tissue protective treatments that have little or no potentially detrimental effects and can be made readily available to the public. The discussion of documents, acts, materials, devices, articles and the like is included in this specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all of these matters formed part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application. 3.

Excitable cells are cells that respond actively to an electric stimulus and have an electrical charge differential across their cellular membranes. Excitable cells are generalIy capable of undergoing an action potential. Such cells typically express channels, such as voltage-gated, ligand-gated, and stretch channels which allow flow of ions (potassium, sodium, calcium, chloride, etc.) across the membrane. Excitable tissue includes neuronal tissue, muscle tissue, and glandular tissue. Excitable tissue includes, but is not limited to, neuronal tissues such as tissue of the peripheral nervous system (ear and retina) and central nervous system (brain and spinal cord); cardiovascular tissue such as the cells of the heart and assidated nerves and glandular tissue such as the pancreas where T-type calcium channels along with cell-to-cell gap junctions participate in secretion of insulin An exemplary list of excitable tissue includes organs and 15 tissues that include nerves, skeletal muscle, smooth muscle, cardiac muscle, uterus, central nervous system, spinal cord, brain, retina, olfactory system, auditory system, etc. (xiv) The term "hematopoietic activity" means any significant increase in blood cellular components such as erythroid. lymphoid, and myeloid cells.

The "inflammatory condition" may be acute or chronic. (xvii) An "isolated" or "purified" peptide is substantially free of cellular material or other contaminating proteins from the cell or tissue source from which the protein or peptide is derived, or substantially free of chemical precursors or other chemicals when chemically synthesized. The language "substantially free of cellular material" includes preparations of a peptide in which the peptide is separated from cellular components of the cells from which it is isolated or recombinantly produced. Thus, a peptide that is substantially free of cellular material includes preparations of peptides having less than about 30%, 20%, 10%, or 5% (by dry weight) of heterologous protein (also referred to herein as a "contaminating protein") When the peptide is recombinantly produced, it is also preferably substantially free of culture medium, ie culture medium represents less than about 20%, 10%, or 5% of the volume of the 17 protein preparation. When the peptide is produced by chemical synthesis, it is preferably substantially free of chemical precursors or other chemicals, i.e., it is separated from chemical precursors or other chemicals which are involved in the synthesis of the protein. Accordingly such preparations of the peptide have less than about 30%, 20%, 10%, 5% (by dry weight) of chemical precursors or compounds other than the peptide of interest. In a preferred embodiment, peptides of the invention are isolated or purified. (xviii) An "isolated" nucleic acid molecule is one which is separated from other nucleic acid molecules which are present in the natural source of the nucleic acid molecule. Moreover, an "isolated" nucleic acid molecule, such as a eDNA molecule, can be substantially free of other cellular material, or culture medium when produced by recombinant techniques, or substantially free of chemical precursors or other chemicals when chemically synthesized. In a specific embodiment, a nucleic acid molecule(s) encoding a peptide of the invention is isolated or purified. (xix) As used herein, the term "management" includes the provision of one or more beneficial side effects that a patient derives from a peptide which, in one embodiment, does not reverse the damage, effects or symptoms of a a disease or disorder associated with tissue damage. In certain embodiments, a patient is administered a peptide to "manage" the symptoms of a disease or disorder associated with tissue damage so as to prevent the progression or worsening of the symptoms. (xx) The terms "modulate," "modulations" and the like refer to the ability of a compound to increase or decrease the function and/or expression of mediators of the body's response to a disease or disorder associated with tissue damage, including transcription of regulatory activity and/or protein binding. Modulation, as described herein, includes the inhibition antagonism, partial antagonism, activation, agonism or partial agonism of a function or characteristic associated with the mediator, either directly or indirectly, and/or the upregulation or downregulation of the expression of the mediator. In a preferred embodiment, the modulation is direct, and more preferably the modulation occurs through an inhibitor or antagonist of the mediator, a compound that binds to, partially or totally blocks stimulation, decreases, prevents, inhibits, delays activation, inactivates desensitizes, or downregulates signal transduction. The ability of a particular peptide useful in the method of the current invention to inhibit the function of a mediator can be demonstrated in a biochemical assay, e.g. binding assay, cell based assay, e.g. transient transfection assay, or in vivo assay, e.g. animal model of neuronal injury, cancer, inflammation, or chemical or radiation injury such as a rat or murine 18 modeL (xxi) As used herein in reference to a structure within a peptide, the term "motif" refers either to a set of consecutive amino acids within the amino acid sequence of the peptide chain and/or to a set of linearly or spatially adjacent amino acids within the secondary and/or tertiary structure of said peptide. Because the motif may be formed all or in part as a result of protein folding, amino acids that are adjacent in the described motif may be separated by 0, 1 or more, 5 or more, 10 or more, 15 or more or 20 or more amino acids within the linear amino acid sequence of the peptide. (xxii) As used herein, the terms "peptide," polypeptidee" and "protein" are used interchangeably and in their broadest sense to refer to constrained (that is, having some element of structure as, for example, the presence of amino acids which initiate a 0 tum or p pleated sheet, or for example, cyclized by the presence of disulfide bonded Cys residues) or unconstrained (e.g., linear) amino acid sequences. In certain embodiments, the peptide of the invention consists of less than 30 amino acids. However, upon reading the instant disclosure, the skilled artisan will recognize that it is not the length of a particular peptide but its ability to bind a tissue protective receptor complex and/or compete with the binding of a peptide described herein that distinguishes the peptides useful in the method of the current invention. The tennis "peptide," "polypeptide," and "protein" also refer to compounds containing amino acid equivalents or other non-amino acid groups, while still retaining the desired functional activity of a peptide or protein. Peptide equivalents can differ from conventional peptides by the replacement of one or more amino acids with related organic acids (such as PABA), amino acid equivalents or the like or the substitution or modification of side chains or functional groups. (xxiii) The term "preventing the damages, effects or symptoms of a disease or disorder associated with tissue damage" means delaying the onset, hindering the progress, hindering the appearance, protection against, inhibiting or eliminating the emergence, or reducing the incidence, of such damages, effects or symptoms. Use of the term "prevention" is not meant to irply that all patients in a patient population administered a preventative therapy will never be affected by or develop symptoms in response to the disease or disorder associated with tissue damage targeted for prevention but rather that the patient population will exhibit a reduction in the damage, effects, or symptoms of the disease or disorder. For example, many flu vaccines are not 100% effective at preventing flu in those administered the vaccine. One skilled in the art can readily identify patients and situations for whom preventative therapy would be beneficial, such as, but not limited to, individuals about to engage in activities that may expose 19 them to various toxic agents or traumas (e.g., soldiers engaging in military operations, chemical or food processing workers, emergency personnel or first responders, etc.), or individuals that may be subjected to exposure to a toxic agent (e g., individuals living in the vicinity of chemical, nuclear, or manufacturing facilities, or individuals under threat of military or terrorist attack). (xxiv) As used herein, a "prophylactically effective amount" refers to that amount of a peptide sufficient to result in the prevention of the damage, effects or symptoms resulting from a disease or disorder associated with tissue damage. A prophylactically effective amount can refer to the amount of a peptide sufficient to prevent the damage, effects or symptoms resulting from a disease or disorder associated with tissue damage. Further, a prophylactically effective amount with respect to another prophylactic agent means that amount of that prophylactic agent in combination with a peptide that provides a prophylactic benefit in the prevention of damage, effects or symptoms resulting from a disease or disorder associated with tissue damage. Used in connection with an amount of a peptide, the term "prophylactically effective amount" can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of or provides a synergistic affect with another prophylactic agent. (xxv) The term neoplasmm" refers to abnormal growths that lack the malignant properties of cancerous tumors, and are generally mild and non-progressive tumors. Neoplasms include but are not limited to moles, uterine fibroids, thyroid adenomas, adrenocortical adenomas, pituitary adenomasand teratomas (xxvi) The term "radiation agentI" as used herein means any radioactive materia that may kill or injure a subject, and may be used to cause disruption upon a city or nation Exposure to a radiation agent may occur through deployment of a weapon (nuclear bomb (fission, fusion, neutron, boosted fission, or salted bombs), shells containing depleted uranium) terrorist device ("dirty bonb"), or fallout resulting from the detonation of a nuclear weapon or failure of a nuclear plant.

(xxvix) As used herein, the term "tissue protective activity" or "tissue protection" refers to the effect of inhibiting dr delaying damage or death of a cell, tissue, or 21 organ. Unless otherwise noted, the "delay" in damage or death of a cell, tissue or organ is evaluated relative to a control condition in the absence of a peptide of the invention. Tissue protective activity is specific to tissue, cels, and/or organs expressing a tissue protective receptor complex (ite. a responsive tissue cell, and/or organ, respectively), such as, but not limited to, the tissues of the central nervous system, In specific embodiments, the responsive cells are not erythrocyte progenitor cells. (xxx) The tern "tissue protective receptor complex" as used herein means a complex comprising at least one erythropoietin receptor subunit and at least one beta common receptor subunit. The tissue protective receptor complex may contain multiple erythropoietin receptor subunits and/or beta common receptor subunits, as well as other types of receptors or proteins, See WO 2004/096148, which is hereby incorporated by reference herein in its entirety (xxxi) The term "toxic agent" as used herein refers to the biological, chemical and radiation agents mentioned above. (xxxii) To determine the percent identity of two amino acid sequences, the sequences are aligned for optimal comparison purposes. The amino acid residues at corresponding amino acid positions are then compared, When a position in the first sequence is occupied by the same amino acid residue as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % identity number of identical overlapping positions x 100/total number of positions). In one embodiment, the two sequences are the same length. In an alternate embodiment, the sequences are of different length and, accordingly, the percent identity refers to a comparison of the shorter sequence to a portion of the longer sequence, wherein said portion is the same length as said shorter sequence. (xxxiii) As used herein, the term "treatment" includes the elimination, reduction management or control of damage, effects or symptoms resulting from a disease or disorder associated with tissue damage or the damage, effects, or symptoms thereof. 5. BRIEF DESCRIPTION OF THE FIGURES FIG I is a chart regarding the proliferation of UT-7 EPO cells in the presence of EPO or Peptide ID (SEQ ID NO: 282). As shown in the graph, EPO led to a proliferation of the UT-7 EPO cells whereas Peptide ID at all doses did not result in proliferation of the cells, demonstrating that Peptide ID is not erythropoietic. 22 FIG 2 is a chart indicating the hemoglobin concentration in Sprague Dawley rats administered Peptide ID twice daily i.v. over a 28 day period. As shown in the graph, the hemoglobin concentration of the rats that received no peptide was the same as those that received Peptide ID, thereby demonstrating that Peptide ID is non erythropoietic. FIG 3 is a series of bar graphs illustrating the (a) hemoglobin concentration, (b) hematocrit, and (c) platelet count in blood samples taken from New Zealand White Rabbits administered various doses of Peptide ID twice daily ix. for a period of 28 days. As shown in the graphs, the administration of Peptide ID, at all doses, had no effect on the hemoglobin concentration, hematocrit, or platelet count of the animals. FIG 4 is a bar graph indicating the relative survival of motomeurons subjected to kainic acid. As is shown in the graph, those cells pretreated with either Peptide B (SEQ ID NO: 3) or EPO exhibited improved survival rates. FIG 5 is a chart illustrating the De Ryck scores of rats subjected to a foot fault test following middle cerebral artery occlusion and treatment with either saline, Peptide ID or Peptide IX (SEQ ID NO: 301). As shown in the chart, Peptide ID significantly improved the rats performance in the foot fault protocol (11.2 ± 1.1 foot faults) in comparison to the saline treated rats (20.2 * 0.8 foot faults) and Peptide IX treated rats (20.1 ± 2.1 foot faults). FIG 6 is a series of graphs relating to the concentration of creatinine (Graph A), urea (Graph B), and aspartate aminotransferase (AST) (Graph C) in the serum of mice that had been subjected to 30 minutes of bilateral renal ischemia followed by a period of 24 hrs of reperfuhsion and received either a control (PBS), I pg/kg of Peptide ID at 1 minute into reperfision, I pg/kg of Peptide ID at 30 minutes into reperfusion, 1 pig/kg of Peptide ID at 6 hours into reperfusion, or 10 jig/kg of Peptide ID at 6 hours into reperfision. As shown in each graph, 1 pg/kg of Peptide ID at 6 hours into reperfusion or 10 pg/kg of Peptide ID at 6 hours into reperfusion resulted in a reduction in these biochemical markers of renal dysfunction. FIG 7 is series of graphs relating to the concentration of creatinine (Graph A), urea (Graph B), and aspartate aminotransferase (AST) (Graph C) in the serum of mice that had been subjected to 30 minutes of bilateral renal ischemia followed by a period of 24 hrs of reperfusion and received either multiple doses of a control (PBS), 0.1 pg/kg of Peptide ID, I pg/kg of Peptide ID, or 10 pg/kg of Peptide ID at 1 minute, 6 hours and 12 hours into reperfusion. As shown in each graph, I pg/kg of Peptide ID or 10 pg/kg of Peptide ID resulted in a reduction in these biochemical markers of renal dysfunction. 23 FIG. 8 is a chart illustrating the reduction in wound area over a period of treatment in a full thickness punch biopsy wound assay in rats receiving Peptide ID (24 nmnol/kg of bw) daily s e.. As shown in the chart, the wounds on rats receiving Peptide ID healed more rapidly. FIG. 9 is a bar graph showing the results from a novel object recognition test performed on adult Wistar rats that received saline, positive control galantamine (3 mg/kg of bw), or Peptide ID (24 nrnol/kg of bw) at various time points. As shown in the graph, galantamine and Peptide ID increased the rats recognition of the novel objects. FIG 10 is a graph comparing the volume of urine produced by rats treated with cisplatin, cisplatin and peptide IC (SEQ ID NO: 281), or control (PBS). The graph illustrates that the urine volume of the cisplatin and Peptide IC treated rats was substantially like that of the control (PBS) group. Thus the graph demonstrates that in a model of cisplatin induced nephropathy in rats that Peptide IC administered three times weekly at a dose of 0.4 g/kg over a 5 week period protected the treated rats against renal damage due to the cisplatin. FIG. 11 is a graph comparing the times it took a rat to withdraw a paw from the hot plate in rats treated with cisplatin, cisplatin with Peptide IC or control (PBS). The graph illustrates that the time it took the rats treated with cisplatin and Peptide IC to withdraw their paw from the hotplate was substantially similar to the control group (PBS). Thus the graph demonstrates that in a model of cisplatin induced neuropathy in rats that Peptide IC administered three times weekly at a dose of 0.4 ptg/kg over a 5 week period protected the treated rats against peripheral neuropathy due to the cisplatin. FIG. 12 is a graph comparing relative volume of a cortical tumor implanted in a rat's brain in accordance with the protocol of Lampson L.A. et al., 193, Cancer Res. 53(1): 176 82 after 25 days. The graph shows that the relative volume of the tumors in the rats treated by saline increased by slightly greater than 0.4 cm 2 whereas the rats treated with Peptide ID following implantation showed no increase in the relative volume of the tumor. FIG. 13 is a graph comparing the relative volume of a cortical tumor implanted in a rat's brain in accordance with the protocol of Lampson L.A. et al., 193, Cancer Res. 53(1): 176-82 after 25 days. The graph shows that the relative volume of the tumors in the rats treated by saline starting two weeks after implantation is about 300 mm 2 greater whereas treatment with Peptide ID and Peptide 1W (an extended half-life peptide, SEQ ID NO: 305) starting two weeks after implantation reduced the size of tumor in both cases. Administration of 24 Peptide IW at two weeks resulted in a reduction in size of the tumor equivalent to that achieved by immediate treatment with Peptide ID. FIG. 14 is a comparison of cortical tumor size in rats treated with saline daily, Peptide ID, or Peptide IW after a two week delay. The darkened areas on the photograph illustrate the presence of the tumor. The comparative photos clearly demonstrate that the administration of Peptide IW after two weeks led to a similar reduction in size of the tumor as administration of Peptide ID immediately after implantation of the tumor. FIG 15 difference in ear thickness in the ears of Sprague Dawley rats intradermally injected with histamine diphosphate. The rats were treated either with Peptide ID intravenously or saline, The ears of the rats treated with Peptide ID exhibited less inflammation in response to the histamine challenge than the ears of the rats treated with saline, FIG 16 is a chart demonstrating the difference in wheal (hive) size on rat abdomens in response to intradermally administered histamine in those rats pretreated with saline and those pretreated with Peptide ID. The chart illustrates the anti-inflammatory effects of Peptide ID up to 24 hours following the histamine injection. FIG 17 is a chart demonstrating the difference in wheal (hive) area in response to a histamine challenge in rats between those rats treated with EPO and those rats treated with saline. The wheal area after fifteen (15) minutes was less those treated with EPO than those rats treated with saline. FIG 18 is a chart comparing the difference in wheal (hive) size (lesion area) in rats challenged with histamine and treated using saline, Peptide IY (SEQ ID NO: 304), Peptide ID and Peptide 1W. Animals treated with either Peptide ID or Peptide 1W exhibited nearly half the lesion area (about 35 cm 2 and .3 cm. respectively) of the lesions on the saline and Peptide IY treated animals (about .6 cm). FIG 19 is a chart comparing the difference in wheal (hive) size (lesion area) in rats challenged with histamine and treated using saline, Peptide JA (SEQ ID NO: 301), Peptide 1W, Peptide IZ (SEQ ID NO: 300), and Peptide ID. Animals treated with either peptide 1W, IZ, or ID exhibited a smaller lesion area (.3 cm 2 , 35 and .4 cm 2 respectively) in comparison to the saline and peptide JA treated animals (both about 6 cm 2 ). FIG. 20 is a chart comparing the difference in wound (ulcer) size (area) in rats subjected to a pressure ulcer and treated using saline, Peptide ID dosed twice, Peptide ID dosed daily or EPO administered daily. The chart demonstrates that the Peptide ID and EPO treated rats exhibited better wound healing than the saline treated rats. With the Peptide ID daily treated 25 animals had the smallest wound size. FIG 21 shows Kaplan Meier Survival Curves for mice irradiated with 796cGy (A) or 831 eGy (B) and then treated with Peptide ID subcutaneously daily for 29 days following irradiation or with PBS subcutaneously for 29 days. At both doses of radiation, Peptide ID significantly increased the overall survival time of the mice at day 30 (45% survival at day 30 at 796cGy, 20% survivaI at day 30 at 831cGy) FIG 22 is a chart showing the survival rate of mice that received partial body irradiation of I15Gy and then were treated with Peptide ID at day I and daily thereafter or PBS at day one and daily thereafter, As the chart shows, the number of mice surviving to day 20 was substantially greater amongst those receiving Peptide ID in comparison to those receiving PBS (6 peptide treated mice vs. i PBS treated mouse). 6.

Certain amino acid residues in the core peptides and peptide analogs of Formula IV can be replaced with other amino acid residues without significantly deleteriously affecting and in many cases even enhancing, the activity of the peptides and peptide analogs. Thus, also contemplated by the present invention are altered or mutated forms of the isolated peptides and peptide analogs of Formula IV wherein at least one and up to eight amino acid residues in the formula are conservatively substituted with another amino acid residue. In certain embodiments, seven, six, five four, three, two, or one amino acid is conservatively substituted. In specific embodiments, the isolated peptides and peptide analogs are selected from the group of peptides set forth below: Peptide M APPRLICDSRVLERYLLEAKE (SEQ ID NO: 32); and Peptide N HCSLNENITVPDTKVNFYAWKRMEV (SEQ ID NO: 33). 36 One of ordinary skill in the art will recognize that it is the above noted structural motifs A and B that is important to the current invention. Thus one of ordinary skill in the art would recognize that the isolated peptide may have less than 90 %, less than 85%, less than 80%, less than 75%, less than 70%, less than 65%, less than 60%, less than 55%, less than 50%, less than 45%, less than 40%, less than 35%, less than 30%, or less than 20 percent sequence identity with any portion of the amino acid sequence of mature human EPO set forth in SEQ ID NO: 1, wherein said portion of EPO contains the same number of amino acid residues as said peptide, Applicants further propose that the tissue protective activity of structural motifs A and B is due to an appropriate, spatially compact charge configuration generated by the motifs. The proximity of these charges may occur via the linear structure imposed by peptide bonding, i.e., the structure may be formed by consecutive amino acids in a polypeptide chain, or alternatively, proximity can also occur via a spatial relationship between different parts of the EPO molecule (or other related Type I cytokine molecules) imparted by the protein's secondary and/or tertiary structure, i.e., three dimensional structure. Not wishing to be bound to any specific theory, Applicants believe that, in general, this requirement dictates that a tissue protective peptide will have a distinct tertiary structure (e.g., helices or pleated sheets) that provides for the required spatial location of the pair of charged amino acids (i.e., the two negatively charged amino acids and/or the positively and negatively charged amino acid). A simple exception is a linear peptide wherein the amino acid pair is immediately adjacent to each other, with the required rigidity imparted by the peptide backbone. Accordingly, the structural motif A, is encompassed by a linear sequence of amino acid residues, e.g., H 1

-N

1

-N,-H

2 (SEQ ID NO: 6), or by a linear sequence of amino acid residues wherein N, and N 2 are separated by 1, 2, 3, 4, 5, 6, or more intervening residues, e.g., H-N-X-X-X-X-X-N-H (SEQ ID NO: 11). Not wishing to be bound by any particular theory, Applicants believe that for tissue protection, the pair of charged amino acids in the peptide must be spatially oriented such that the carbamyl carbons are about 3 angstroms (A) to about 5 A apart, preferably, about 4 A to about 5 A apart, and more preferably about 4.4 A to about 4.8 A apart. This can be accomplished in a number of ways, for example, by adjacent charged amino acids in a simple linear peptide or for peptides that can form an alpha helix, charged amino acids separated by an intervening amino acid residue. It is to be noted that tertiary structure (e.g., an alpha helix in amphipathic peptides) can also be imparted when the peptide is within a specific 37 microenvironment, such as at the extraceilular-cell surface membrane interface(ee, Segrest, 1990, Proteins 8:103-117, hereby incorporated by reference in its entirety) Further, tissue protectve activity is predicted for peptides that contain pairs of charged amino acids such that the charged side-chains (either positive and negative or two negatives) be confined spatialy to within about 6.5 A to about 9 A of each other. This can be provided for in an alpha helix by the charged pair being separated by one or two amino acids, which will provide for the charges to be more or less on the same side of the helix with the required about 65 A to about 9 A separation. One skilled in the art can devise a tertiary structure for the peptide that is generally required to obtain the appropriate three dimensional location of the charged amino acids, as well as the design of small molecules to mimic the charge separation within the peptide. The spatial distances between the carbamyl carbons of any two amino acids or between the side chains of any two amino acids can be deduced by any method known in the art or described herein. For example, where the three-dimensional structure of the protein is known, the charge separation of two side chains or the spatial distance between two carbamyl carbons within a portion of interest of said protein can be calculated bed d on the published, or otherwise art-accepted, three-dimensional coordinates of the amino acid residues in said portion of interest. Where the three-dimensional structure of the protein and, therefore, the portion of interest is unknown, or wherein a fully synthetic peptide is constructed based on the teachings herein whose three dimensional structure is unknown, the charge separation of two side chains or the spatial distance between two carbamyl carbons within said peptide can be estimated using the three-dimensional structure predicted by protein modeling software as is known in the art. Non-limiting examples of such software are MOErM by Chemical Computing Group (Quebec, Canada) and Modeler by Accelrys (San Diego, California). Similarly such predictive software, available from the above-noted companies as well, is also known in the art for the design of small molecules as and, accordingly, one of ordinary skill in the art, based upon the teachings herein, would be able to make small molecules that emulate the disclosed structural motifs. c.

The above motifs are not only useful in identifying EPO derived peptides or EPO agonist fragments but fragments of Type-I cytokines that also exhibit the ability to inhibit or 44 retard a disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom and are therefore therapeutically effective at preventing, treating ameliorating or maintaining a disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom. The Type-I cytokine family includes, but is not limited to, interdeukin (IL2, IL3 1-4, IL-5, IL-6, IL-7 I-9, IL-I0, or IL-1, granulocyte macrophagecolony stimulating factor (GM-CSF), leptin, granulocyte colony stimulating factor (G-CSF); leukemia inhibiting factor (LIF), ciliary neurotrophic factor (CNTF, thrombopoietin (TPO), growth hormone, macrophage colony stimulating factor (M-CSF), erythropoietin (PO) and prolactin. Consideration of the secondary structure of EPO provides guidance for the preparation of a candidate peptide via the spatial arrangement of amino acids derived from homologous amino acids located within homologous secondary structures within other Type-I cytokine receptor ligands: e.g., GM-CSF and IL-3 (Kannan, 2000, Neuroimmunomd 8:132 141, hereby incorporated by reference in its entirety), among others, have been shown to possess potent neurotrophic and neuoprotctive activities, due in large part, the Applicants believe, by stimulating a tissue protective receptor.

In other words, a chimeric peptide may be comprised of amino acid sequences derived from non-linear but adjacent structural elements such as a fragment derived from amino acid sequences 110-115, 133-136, and 160-165, of SEQ ID NO:I which would allow structural elements of the C terminal portion of helix C and N-terminal portion of loop C-D, the n-pleated sheet in loop C-D, and the C terminal portion of EPO to be contained in a single peptide. Additionally, chimeric peptides may be used to select out the important features of a particular structure, for example the 61 externally-facing amino acids of a particular tertiary structure. Thus, a chimeric peptide useful in the methods of the current invention may consist of a fragment comprised of helix B aTino acids 58, 62, 65, 69, 72, 76, 79, 80, 83, 84, and 85 (e.g., peptide IC, QEQLERALNSS, SEQ ID NO: 281) or, in other words, all of the exterior-presenting amino acids of helix B of EPO, as disclosed in PCT/US2006/031061 A further chimeric peptide in which the fist glutamine is replaced with pyrogiutamate (e.g. peptide ID, UEQLERALNSS, SEQ ID NO. 282) is contemplated by the current invention as well, Further, non-nturally occurring or chimeric peptides can be designed that imiic the critical spatial proximities between carbamyl carbons of any two amino acids or between the side chains of any two amino acids in erythropoietin or another Type-I cytokine described herein above via a linear sequence of amino acids and may provide a guide in evaluating possible tissue protective chimeras derived from other proteins. The present invention is, therefore. directed to novel chimeric tissue protective peptides, including those that exhibit these structural motifs and critical spatial proximities that trigger tissue protection Furthermore, the potency of the current peptides may be increased by attaching an amphipathic peptide helix. Amphipathie peptide helices are well known in the art, e.g. from peptides that signal through the Class B G-protein coupled receptors (e.g., Segrest et al., 1990, Proteins 8:103, hereby incorporated by reference in its entirety), serving to localize the peptide ligand to the cell membrane. Examples of such helices include, but are not limited to, the highly hydrophobic regions from: calcitonin (Peptide IE:ALSILVLLQAGS, SEQ ID NO:283) corticotropin releasing hormone (Peptide IF:VALLPCPPCRA, SEQ ID NO:284); beta endorphin (Peptide IG:NAIIKNAYKK, SEQ ID NO:285); glucagon (Peptide 1H:GSWQRSLQDTE, SEQ ID NO:286); secretin (Peptide II:GGSAARPAPP, SEQ ID NO:287); vasointestinal peptide (Peptide IJNALAENDTPYY SEQ ID NO:288); neuropeptide Y (Peptide IK:GALAEAYPSKP, SEQ ID NO:289); gonadotropin releasing hormone (Peptide IL:GCSSQHWSYGL, SEQ ID NO:290); parathyroid hormone|(Peptide IM:VMIVMLAICFL SEQ ID NO:291); pancreatic polypeptide(Peptide IN:LRRYINMLTRP, SEQ ID NO:292); and calcitonin gene related peptide (Peptide IO:LALSILVLYQA, SEQ ID NO:293) (disclosed in Grace et al., 2004, PNAS 101:12836,hereby incorporated by reference in its entirety). For example, a chimeric peptide useful in the methods of the current invention may be made from a peptide with the surface charge motif of helix B of EPO (Peptide IC;QEQLERALNSS, SEQ ID NO:281) joined at the carboxy terminus to the amphipathic heiix of pancreatic polypeptide (Peptide N:LRRYINMLTRP, SEQ ID NO292)6for a chimeric peptide (Peptide 62 IP:QEQLERALNSSLRRYINMLTRP, SEQ ID NO 293), as disclosed in PCT/US2006/031061. Further modifications may be made to the carboxy terminus of the amphipathic helix without affecting its tissue protective properties. Thus, a further example of a peptide useful in the treatment of a disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom is generated by replacing the terminal Pro of the above chimeric peptide with the sequence TR (Peptide IQ:QEQLERALNSSLRRYfNhMLTRTR, SEQ ID NO:294). Additionally, instead of the above-noted helices, other tertiary structures can be attached to the peptides. For example, the helix B exterior-presenting amino acids can be linked to the beta pleated sheet (Peptide IR:CSLNENI, SEQ ID NO:295) found within the AB loop of EPO to form a chimeric peptide having the sequence Peptide IS:CSLNENIQEQLERALNSS (SEQ ID NO:296). Additionally, the presenting amino acids of the terminal portion of helix C (Peptide IT:ALGKA, SEQ ID NO:297, corresponding to amino acids 1,1 112,113,116, and 118 of SEQ ID NO: 1) may be combined with all or part of loop CD-partial (Peptide IU:LGAQKEAiSPPDA ASAAPLRTI, SEQ ID NO:298, corresponding to amino acids 112-133 of SEQ ID NO:i) to form Peptide IV:ALGKALGAQKEAISPPDAASAAPLRT (SEQ ID NO: 299). Additiona!y, isolated peptides exhibiting the various motifs disclosed above Structural Motifs A (including Formulas I-IV), Structural Motif B (including Formulas V-X), Structural Motif C, Structural Motif D, Structural Motif E and Structural Motif F- may be combined to form various chimeras as well. In certain embodiments, the chimeras will exclude Peptide IC, QEQLERA LNSS, SEQ ID NO: 281, Peptide IP:QEQLERALNSSLRRYINMLTRP, SEQ ID NO: 293, Peptide IQ:QEQLERALNSSLRRYINMLTRTR, SEQ D NO:294, Peptide IS:CSLNENIQEQLERALNSS, SEQ ID NO:296, Peptide IT:ALGKA, SEQ ID NO:297, and Peptide IV:ALGKALGAQKEAISPPDAASAAPLRTI, SEQ ID NO: 299. Preferably, a linking arm will be present between the fused peptides to provide for flexibility so that the joined peptides can assume the proper structural orientation to bind with the tissue protective receptor complex Such fusion peptides may have a synergistic effect obtaining a greater tissue protective effect jointly as opposed to individually possibly through enhanced binding with the tissue protective receptor complex or increased biological half life. One of ordinary skill in the art will recognize the benefit of combining various desired structural elements in to a single peptide for maximizing the efectiveness of such compounds in the method of preventing, treating, amehiorating or managing damages, effects, or symptoms resulting from exposure to a toxic agent in accordance with the current invention. 63 Such chimeras may comprise amino acids peptides and non-amino acid elements, such as linkers or bridging atoms or moietes 6.4 Fusion Peptides The present invention further contemplates that two or more of the above noted peptides, fragment derived or chimera, may be linked to a related or unrelated protein such as erythropoietin, albumin, etc. Such fusion peptides may be generated in order to achieve synergistic benefitsncrease the circulating half-life of the peptide, or increase the ability of the peptide to penetrate endothelial barriers, such as the blood-brain barrier, blood-retina baffier, etce, or vice versa, i.e. to act as a transport mechanism similar to that disclosed in PCT/USO1/49479 published as WO 2002/053580 hereby incorporated in its entirety by reference. 6.5 Manufacture of Peptides Peptides useful in the method of the current invention may be made using recombinant or synthetic techniques well known in the art. In particular, solid phase protein synthesis is well suited to the relatively short length of the peptides and may provide greater yields with more consistent results. Additionally, the solid phase protein synthesis may provide additional flexibility regarding the manufacture of the peptides. For example, desired chemical modifications may be incorporated into the peptide at the synthesis stage: homocitrulline could be used in the synthesis of the peptide as opposed to lysine, thereby obviating the need to carbanylate the peptide following synthesis or amino acids with protected functional groups may be left on the peptide during synthesis. Synthesis The isolated peptides and peptide analogs useful in the method of the current invention may be prepared using conventional step-wise solution or solid phase synthesis (see, e.g. Merrifield, RB., 1963,1Am Chen Soc 85:2149-2154; Chemical Approaches to the Synthesis of Peptides and Proteis, Williams eta., Eds., 1997, CRC Press, Boca Raton Fla, and references cited therein; Sold Phase Peptide Synthesis: A Practical Approach, Atherton & Sheppard, Eds., 1989, IRL Press, Oxford, England, and references cited therein). Alternatively, the peptides and peptide analogs useful in the current invention rnay be prepared by way of segment condensation, as described, for example, in Liu et al. 1996, Tetrahedron Lett 37(7):933-936; Baca, et al- 1995,1 Am, Chem. Soc 117:1881-1887; Tam er 64 al, 1995, Int J Peptide Protein Res. 45:209-2 16; Schnoizer and Kent, 1992, Science 256:22 1 225; Liu and Tam 1994,. Am. Chem. Soc. I i16(10):4149-4153; Liu and Tan, 1994, Proc. Nat Acad Sci USA 91:6584-6588; Yamashiro and Li, 1988, hnt. J Peptide Protein Res. 31 :322 334 This is particularly the case with Gly (G) containing peptides. Other methods useful for synthesizing the peptides and peptide analogs of the invent on are described in Nakagawa et al., 1985nJ. Am. Chem. Soc. 107:7087-7092 Reumnnoant Techique A variety of host-expression vector systems may be utilized to produce the peptides and peptide analogues. Such host-expression systems represent vehicles by which the peptide of interest may be produced and subsequently purified, but also represent cells that ray, when transformed or transfected with the appropriate nucleotide coding sequences, exhibit the modified erythropoietin gene product in situ. These include but are not limited tobacteria, insect, plant, mammalian, including human host systems, such as, but not limited to, insect cell systems infected with recombinant virus expression vectors (e g. baculovirus) containing the peptide coding sequences; plant cell systems infected with recombinant virus expressionvectors (e g., cauliflower mosaic virus, CaMV; tobacco mosaic virus, TMV) or transformed with recombinant plasmid expression vectors (e g., Ti plasmid) containing erythropoietin-related molecule coding sequences; or mammalian cell systems, including human cellsystems,eg., HT1080, COS, CHO, BHK, 293, 3T3, PERC6 harboring recombinant expression constructs containing promoters derived from the genome of mammalian cells, e.g., metallothionein promoter, or from mammalian viruses, e.g, the adenovirus late promoter; the vaccinia virus 7.5K promoter. In addition, a host cell strain may be chosen that modulates the expression of the inserted sequences, or modifies and processes the gene product in the specific fashion desired. Such modifications and processing of protein products may be important for the function of the protein. As known to those of ordinary skill in the art, different host cells have specific mechanisms for the post-translational processing and modification of proteins and gene products. Appropriate cell lines or host systems can be chosen to ensure the correct modification and processing of the foreign protein expressed. To this end, eukaryotic host cells that possess the cellular machinery for proper processing of the primary transcript, glycosylation, and phosphorylation of the gene product may be used- Such mammalian host 65 cells, including human host cells, include but are not limited to HTIO80, CR0, VERO, BHK, HeLa, COS, MDCK, 293, 3T3, and W18. For long-term, high-yield production of recombinant peptides, stable expression is preferred. For example, cell lines that stably express the recombinant tissue protective cytokine-related molecule gene product may be engineered. Rather than using expression vectors that contain viral origins of replication, host cells can be transformed with DNA controlled by appropriate expression control elements, e.g., promoter, enhancer, sequences, transcription terminators, polyadenylation sites, and the like, and a selectable marker. Following the introduction of the foreign DNA, engineered cells may be allowed to grow for 1-2 days in an enriched media, and then are switched to a selective media, The selectable marker in the recombinant plasmid confers resistance to the selection and allows cells to stably integrate the plasmid into their chromosomes and grow to form foci that in tum can be cloned and expanded into cell lines. This method may advantageously be used to engineer cell lines that express the tissue-protective product. Such engineered ellines may be particularly useful i screening and evaluation of compounds that affect the endogenous activity of the EPO-related molecule gene product. Further Modificatins Peptides with additional modifications can also be used in the method of the present invention for preventing, treating, ameliorating or managing a disease or disorder associated with tissue damage or damageeffects or symptoms resulting therefron. For example, the peptides of the above-noted structural motifs may be synthesized with one or more (D)-amino acids. The choice of including an(L) or (D)- amino acid into a peptide of the present invention depends, in part, upon the desired characteristics of the peptide. For example, the incorporation of one or more (D)-amino acids can confer increasing stability on the peptide in vitro or in vivo. The incorporation of one or more (D)-amino acids can also increase or decrease the binding activity of the peptide as determined, for example, using the bioassays described herein, or other methods well known in the art. Replacement of all or part of a sequence of (L)-amino acids by the respective sequence of entatiomeric (D)-amino acids renders an optically isomeric structure in the respective part of the peptide chain. Inversion of the sequence of all or part of a sequence of (L)-anino acids renders retro-analogues of the peptide. Combination of the enantiomeric (L to D, or D to L) replacement and inversion of the sequence rendersretro-inverso-analogues of the 66 peptide. It is known to those skilled in the art that enantiomeric peptides, their retro-analogues and their retro-inverso-analogues maintain significant topological relationship to the parent peptide, and especially high degree of resemblance is often obtained for the parent and its retro inverso-analogues. This relationship and resemblance can be reflected in biochemical properties of the peptides, especially high degrees of binding of the respective peptides and analogs to a receptor protein. The synthesis of the properties of retro-inverso anologues of peptides have been discussed for example in Methods of Organic Chemistry (Houben-Weyl), Synthesis of Peptides and Peptidomimetics Workbench Edition Volume E22c (Editor-in-chief Goodman M.) 2004 (George Thieme Verlag Stuttgart, New York), and in references cited therein, all of which are hereby incorporated by reference herein in their entireties Amino acid "modification" refers to the alteration of a naturally occurring amino acid to produce a non-naturally occurring amino acid. Derivatives of the peptides of the present invention with non-naturally occurring amino acids can be created by chemical synthesis or by site specific incorporation of unnatural amino acids into peptides during biosynthesis as described in Christopher J. Noren, Spencer J. Anthony-Cahill, Michael C. Griffith, Peter G. Schultz, 1989 Science, 244:182-188, hereby incorporated by reference herein in its entirety. Peptide mimetics that are structurally similar to therapeutically useful peptides may be used to produce an equivalent therapeutic or prophylactic effect. Generally, peptidomimetics are structurally similar to a paradigm polypeptide (ie.a polypeptide that has a biochemical property or pharmacological activity), but have one or more peptide linkages optionally replaced by a linkage selected from the group consisting of: --CH-NH --CH 2

, Such peptide mimetics may have significant advantages over peptide embodiments, including, for example: more economical production, greater chemical stability, enhanced pharmacological properties (half-life, absorption, potency, efficacy, etc.), altered specificity (eig, a broad-spectrum of biological activities) reduced antigenicity, and others. A variety of designs for peptide mimetics are possible. For example, cyclic peptides, in which the necessary conformation is stabilized by non-peptides, are specifically contemplated, U.S. Patent No. 5,192,746 to Lobi, et at., U.S. Patent No, 5,576,423 to Aversa, et al,, U.S. Patent No. 5,051,448 to Shashoua, and U.S. Patent No. 5,559,103 to Gaeta, et at, all hereby incorporated by reference, describe multiple methods for creating such compounds. Synthesis of nonpeptide compounds that mimic peptide sequences is also known in the art. Eldred et al., J. Med. Chen. 37:3882 (1994), hereby incorporated by reference herein in its entirety) describe non-peptide antagonists that mimic the peptide sequence. Likewise, Ku et al., J. Med. Chem 38:9 (1995) (hereby incorporated by reference herein in its entirety) further elucidates the synthesis of a series of such compounds. Further modifications following synthesis may be implemented. For example, the peptides may be further chemically modified, i.e. carbamylated, acetylated, succinylated, guanidated, nitrated, trinitrophenylated, amidinated, etc., in accordance with U.S. Patent Application No. 10/188,905, which published as 20030072737-Al on April 17, 2003 and discloses chemically modified EPO, and in accordance with U.S. Patent Application No.10/612,665, filed July 1, 2003, and U.S. Patent Application No. 09/753,132, filed December 29, 2000, which are incorporated by reference herein in their entirety. Additionally, the peptides may consist of recombinant peptides -- muteins. The disclosed mutations may include substitutions, deletions, including internal deletions, additions, including additions yielding fusion proteins, or conservative substitutions of amino acid residues within and/or adjacent to the amino acid sequence, but that result in a "silent" change, and non conservative amino acid changes and larger insertions and deletions, as previously disclosed in PCT/JS03/20964 entitled Recombinant Tissue Protective Cytokines and Encoding Nucleic Acids Thereof for Protection, Restoration, and Enhancement of Responsive Cells, Tissues, and Organs (which is incorporated by reference herein in its entirety) 68 Either conservative or non-conservative amino acid substitutions can be made at one or more amino acid residues. Both conservative and non-conservative substitutions can be made, Conservative replacements are those that take place within a family of amino acids that are related in their side chains. Genetically encoded amino acids can be divided into four families: (1) acidic = Asp (D), Glu (G); (2) basic = Lys (K), Arg (R), His (H); (3) nonpolar (hydrophobic) = Cys (C), Ala (A), Val (V), Leu (L), lie (I), Pro (P), Phe (F), Met (M), Trp (W), Gly (G), Tyr (Y); and (4) uncharged polar = Asn (N), Gin (Q), Ser (S), Thr (T). Non-polar may be subdivided into: strongly hydrophobic Ala (A), Val (V), Leu (L), Ie (1), Met (M), Phe (F); and moderately hydrophobic = Gly (G), Pro (P), Cys (C), Tyr (Y), Trp (W). In alternative fashion, the amino acid repertoire can be grouped as (1) acidic = Asp (D), Glu (G); (2) basic Lys (K), Arg (R), His (H), (3) aliphatic = Gly (G), Ala (A), Val (V), Leu (L), Ile (I), Ser (S), Thr (T), with Scr (S) and Thr (T) optionally be grouped separately as aliphatic-hydroxyl; (4) aromatic = Phe (F), Tyr (Y), Trp (W); (5) aide= Asn (N), Gu (Q); and (6) sulfur -containing = Cys (C) and Met (M). (See, for example, Biochemistry, 4th ed., Ed. by L, Stryer, WH Freeman and Co., 1995, which is incorporated by reference herein in its entirety). Alternatively, mutations can be introduced randomly along all or part of the coding sequence of a peptide, such as by saturation mutagenesis, and the resultant mutants can be screened for biological activity to identify mutants that retain activity. Following mutagenesis, the encoded peptide can be expressed recombinantly and the activity of the recombinant peptide can be determined. In another embodiment, the peptide may be further modified through the additions of polymers (such as polyethylene glycol), sugars, or additional proteins (such as a fusion construct) in an effort to extend the half-life of the peptide or enhance the peptide's tissue protective effects. Examples of such modifications are disclosed within WO/04022577 A3 and WO/05025606 Al, which are incorporated herein by reference. For example, a polyethylene glycol polymer can be attached to Peptide IC to result in a Peptide IW ((SEQ ID NO: 305) PEG QFQLERALNSS). Depending on the conjugation chemistry selected and the number of reactive sites already present or created on the peptide, one, two, or a selected number of polymers can be appended in a reproducible manner. The principal mode of attachment of a PEG, and its derivatives, to peptides is a non-specific bonding through a peptide amino acid residue (see e.g., U.S Pat. No. 4,088,538, U.S. Pat. No. 4,496,689, U.S. Pat, No. 4,414,147, U.S. Pat. No. 4,055,635, and PCT WO 87/00056). Another mode of attaching PEG to peptides is through the 69 non-specific oxidation of glycosyl residues on a glycopeptide (see e g., WO 94/05332). In these non-specific methods, PEG is added in a random, non-specific manner to reactive residues on a peptide backbone. 7. ASSAYS FOR TESTING PEPTIDES Various assays can be used to determine the utility of the above noted peptides for use in the therapeutic methods of the current invention. The peptides tissue protective activity would be confirmed using various assays known in the art and disclosed within US PatentApplicationNos. 10/554,517, 10/612,665 and 11/997,898. Further, the peptides lack of erythropoietic activity or reduced erythropoietic activity will be confirmed using various in vitro assays , such as EPO dependent cell lines (UT-7), mouse spleen bioassay (Krystal, C. (1983) (a simple microassay for erythropoietin based on 3 1thymidine incorporation into spleen cells for phenyihydrazine treated mice. Exp. Hemantot IL 649-660))t or clonal assays (Spivak, J. Seiber, F. (1983). Erythropoietin. Horm Norm Abnarm. Hun Tissues 3, 63-96), and in vivo assays, such as the ex hypoxic polycythemic mouse assay (Cotes PM, Bangham DR, Bio-assay of erythropoietin in mice made polycythaemic by exposure to air at a reduced pressure,Nature. 1961 Sep 9;191 :1065-7).. Additionally one of ordinary skill in the art will recognize that the peptide's ability to prevent, mitigate or treat a disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom may be confirmed through various assays both in vitro and in vivo, although in certain embodiments in vivo assays may be preferred. 7.1 Tissue protective Assays and Models The peptides utilized in the current method exhibit tissue protective properties, i.e. anti-apoptoitc, neuritogenic, neuroprotective, etc. Peptides in accordance with the present invention may be tested for tissue protective activity, e.g., protecting cells, tissues or organs. Protective activities may be further tested using in vitro and in vivo assays. In vitro tests that are indicative of tissue protective activity include, for example, cell proliferation assays, cell differentiation assays, or detecting the presence of proteins or nucleic acids upregulated by tissue protecdve receptor complex, eg. tissue protective cytokine receptor complex, activity, ga, nucleolin, neuroglobin, cytoglobin, or frataxin. Neuroglobin, for example, may be involved in facilitating the transport or the short-term storage of oxygen, Therefore, oxygen transport or storage assays may be used as an assay to identify or screen for compounds which modulate 70 tissue protective activity. Neuroglobin is expressed in cells and tissues of the central nervous system in response to hypoxia or ischemia and may provide protection from injury (Sun e td. 2001, PNAS 98:15306-15311; Schmid et al, 2003, J. Biol Chem. 276:1932-1935, each of which is incorporated by reference herein in its entirety). Cytoglobin may play a similar role in protection, but is expressed in a variety of tissues at varying levels (Pesce et al, 2002, EMBO 3:1146-1151, which is incorporated by reference herein in its entirety) In one embodiment of the invention. the levels of an upregulated protein in a cell may be measured before and after contacting the peptide to a cell. In certain embodiments, the presence of an upregulated protein associated with tissue protective activity in a cell, may be used to confirm the tissue protective activities of a peptide. Nucleolin may protect cells from damage. It plays numerous roles in cells including modulation of transcription processes, sequence specific RNA-binding protein, cytokinesis, nucleogensis, signal transduction, apoptosis induced by T-cells, chromatin remodelling, or replication. It can also function as a ccl surface receptor DNA/RNA helicase, DNA-dependent ATPase, protein shuttle, transcription factor component, or transcriptional repressor (Srivastava and Pollard, 1999, FASEB J., 13:1911-1922; and Ginisty et at, 1999, j. Cel Sci 2:6772, eachdf which isincorporated by reference herein in its entirety). Frataxin is a protein involved with mitochondrial iron metabolism and has previously been shown to be strongly up-regulated by EPO both in vivo and in vitro (Sturm et al. (2005) Eur J Clin Invest 35: 711, which is incorporated by reference herein in its entirety) Expression of an unregulated protein may be detected by detecting mRNA levels corresponding to the protein in a cell. The mRNA can be hybridized to a probe that specifically binds a nucleic acid encoding the upregulated protein. Hybridization may consist of, for example, Northern blot, Southern blot, array hybridization, affinity chromatography, or in situ hybridization, Tissue protective activity of the peptide of the invention can also be detected using in vitro neuroprotection assays. For example, primary neuronal cultures may be prepared from new born rat hippocampi by trypsinization, and cultured as by any method known in the art and/or described herein e.g in MEM-ll growth medium (Invitrogen), 20 mM D-glucose, 2 mM L-glutamine, 10% Nu-serum bovine; Becton Dickinson, Franklin Lakes, NJ),.2% B27 supplement (Invitrogen), 26.2 mM NaHCO3, 100 U/mI penicillin, and I mg/mI streptavidin (see, e.g., Leist et al., 2004, Science 305:2239-242, hereby incorporated by reference in its 71 entirety). One day after seeding, I pM cytosinearabino-furanoside is added. Thirteen day old cultures are then preincubated with increasing doses of the peptide of interest (3-3000 pM) for 24 h. On day 14, the medium is removed and the cultures challenged with 300 pM NMDA in PBS at room temperature (RT). After 5 rin, pre-conditioned medium is returned to the cultures which are then returned to the incubator for 24 h, The cells are fixed in paraformaidehyde stained by Hoechst 33342 (Molecular Probes, Eugene, OR) and condensed apoptotic nuclei may be counted. NGF (50 ng/ml) and MK80I (1 pM) are included as positive controls. Animal model systems can be used to demonstrate the tissue protective activity of a compound or to demonstrate the safety and efficacy of the compounds identified by the screening methods of the invention described above The compounds identified in the assays can then be tested for biological activity using animal models for a type of tissue damage, disease, condition, or syndrome of interest. These include animals engineered to contain the tissue protective receptor complex coupled to a functional readout system, such as a transgenic mouse. Animal models that can be used to test the efficacy of the cell or tissue protective activity of an identified compound are known in the art and include, for example, protection against the onset of acute experimental allergic encephalomyelitis in Lewis ratsrestoration or protection from diminished cognitive function in mice after receiving brain trauma, cerebral ischenia(stroke") or seizures stimulated by excitotoxins (Brines eta ., 2000, PNAS, 97:10295 10672, which is incorporated by reference herein in its entirety), protection from induced retinal ischemia (Rosenbaum et at al,1997, Vis. Res. 37:3443-51 which is incorporated by reference herein in its entirety), protection from injury to the sciatic nerve, and protection from ischemia reperfusion injury to the heart (in vitro cardiomyocyte studies and in vivo ischemia-reperfusion injury, see, eg , Calvillo et al., 2003, PA'S 100:4802-4806 and Fiordaliso et aL, 2005, PNAS 102:2046-2051,each of which is hereby incorporated by reference in its entirety) Such assays are described in further detail in Grasso et al. (2004) Med Sci Monit 10: BR -3, PCT publication no. W002/053580, or PCT application PCT/US2006/031 61 each of which is incorporated by reference herein in its entirety. The in vivo methods described therein are directed towards administration of EPO, however, tissue protective proteins administered in place of EPO have been identified to also exhibit similar biologic activity, esg., Leist et al (2004) Science 305: 239 242, which is incorporated by reference herein in its entirety. Peptides may be substituted for testing as well. Other assays for determining tissue protective activity of a peptide are well known to those of skill in the art. 72 Alternatively, cell binding assays can be for evaluation of the peptides of the invention; For example, the peptide of interest can be bound to a biological marker such as a fluorescent or radiolabled marker for ease of detection and tested for binding to transfected BaF3 cells expressing EPOR and/or pt recepton In a 96 well plate, eight 1:2 serial dilutions of the peptide of interest in growth medium (RPM! 1640, 10% fetal bovine serum, 1 mM sodium pyruvate, 2 mM L-glutamine) are plated, such that the final volume in each well is about 100 p11 The BaF3 parental line and BaF3 cells transfected with EPOR and/or pareceptor can be washed three times in growth media (see above), pellets suspended in growth medium, and cells counted and diluted in growth media to 5,000 cells/l00 p1. 100 pl of diluted cells are then added to each peptide dilution. The assay plate is then incubated in a 37" C incubator for three to four days. The plate/cells are then washed and the plate is read on a fluorescent plate reader or by other suitable method to detect the level of biomarker associated with the biological activity of the peptide of interest. Similarly, a competitive assay can be utilized to determine if a peptide is tissue protective. In the competitive assay, a compound known to be tissue protective including, but not limited to, tissue protective cytokines such as those disclosed in U.S. Patent Application Nos. 10/188,905 and 10/185,841 (each of which is incorporated by reference herein in its entirety), can be attached to a suitable bio marker. In a 96 well plate eight 1:2 serial dilutions of a known tissue protective compound/biomarker in suitable growth medium and the same dilution series of the known tissue protective compound/biomarker and an excess of the peptide of interest are plated The final volume of each dilution should be about 100 p1. Once again, the BaF3 cells are seeded into the plates as disclosed supra and allowed to incubate. After an appropriate amount of time, the cells are washed and the plate is read on a fluorescent plate reader or by any other suitable method known in the art to detect the biomarker. If the readout of the plates and/or wells containing the known tissue protective compound/biomarker and peptide of interest is less than the eadout of the plates containing only the known tissue protective compound/biomarker then the peptide of interest is tissue protective. Many protein factors discovered to date, including all knovn cytokines, have exhibited activity in one or more factor-dependent cell proliferation assays, and hence these assays serve as a convenient confirmation of cytokine activity. The activity of a peptide can be evidenced by any one of a number of routine factor dependent cell proliferation assays for cell lines including, without limitAtion, 32D, DA2, DAIG TI0, B9, B9/11, BaF3, MC9/G, M+({preB 73 M+), 2E8, RB85, DAl, 123, T1165, HT2, CTLL2, TF-1, Mo7e and CMK. These cells are cultured in the presence or absence of a peptide, and cell proliferation is detected by, for example, measuring incorporation of tritiated thymidine or by colorimetric assay based on the metabolic breakdown of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) (Mosman, 1983, J. immunol Meth. 65:55-63, which is incorporated by reference herein in its entirety). If a peptide exhibits a tissue protective activity, one of ordinary skill in the art would recognize that it would be beneficial to verify the result using one of the neuroprotective and tissue protective assays known to those skilled in the art, such as, but not limited to, P-19 and PC-I2 cell assays. Additionally, various in viva models such as animal models related to spinal cord injury, ischemic stroke, peripheral nerve damage, wounds, or damage to the heart, eyes, kidneys, etc. would be helpful in further characterizing the peptide. Suitable in vitro and in viva assays are disclosed in U-S. PatentApplication Nos. 10/188,905 and 10/185,841, each of which is incorporated by reference herein in its entirety. 72 Assays for specific indications A. Toxic agents. The isolated peptides to be used within the method of the current invention may be demonstrated to inhibit damage, effects or symptoms resulting from exposure to a toxic agent in vitro or in viv using a variety of assays known in the art, or described herein. Further peptides used within the method of the Invention, may be tested in various in vitro assays in the art to determine their ability to prevent, treat, ameliorate, or manage damage, effects or symptoms resulting from exposure to a toxic agent. In general, this is accomplished by selecting an appropriate cell line, subjecting that cell to a toxic agent of interest and treating a portion of the cells with a peptide of interest and determining the cells survival or response in the presence of the toxic agent and in the presence of the toxic agent and the peptide of interest. if the cell exhibits improved survival or a reduction of damage, effects or symptoms in the presence of the peptide, the peptide can be considered to be a possible therapeutic for toxic exposure Further one of ordinary skill in the art will recognize that the peptides ability as a protectant can be evaluated by treating the cells with the peptide prior to the toxic agent challenge.

Further, suitable in vivo assays are known in the art for evaluating the effect of therapeutics on toxic agent exposure. Animal models using rats, mice, guinea pigs, rabbits, pigs, sheep, ferrets, dogs and non-human primates are contemplated as well as transgenic animals that 75 are particularly susceptible to a toxic agent (CD46 mice), In particular, assays known in the art include, but are not limited to: Chemical Agents:(1) Reid,F.M., Sulfur mustard induced skin bums in weaning swine evaluated clinically and histopathologically, Journal of applied toxicology, vol. 20 (SI), pages 5153-8160 (2001) (2) isidore M.

Inflammation Additionally, various in vitro models of inflammation may be used to evaluate a peptides ability to protect or treat the damage, symptoms, or effects of inflammation on the body. Initial, the ability of the peptide to modulate an inflammatory mediator can be confirmed by measuring the levels of the inflammatory mediator in an inflammatory assay after treatment with the peptide by known methods, including but not limited to, ELISA, cytometric bead array analysis, high-sensitivity and immunonephelometric assays. For example to determine if the peptide modulates either TNF-a or IL4, a marine model of LPS-mediated cytokine production would be performed. Some mice in the murine model would be pretreated with the peptide of interest and then challenged with LPS while others would be saline treated. Blood would then be collected and the TNF-a and IL-I levels in the blood could be determined 76 by an ELISA kit (OPT-EIA mouse TNF-q and IL- ELISA kits (BD Biosciences). If the TNEt levels in the treated animals are lower than the TNFp levels in the saline treated animals then the peptide could be considered to modulate TNFt. Preferably, the peptide would be tested for its ability to modulate more than one inflammatory mediator, and more preferably it would be a mediator other than or in addition to TNF-a, and most preferably it would be histamine. Similarly, the peptides may be tested in additional in vitro assays including, but not limited to, those disclosed in Lopata, Andreas LSpecialized intro Diagnostic Methods In The Evaluation Of Hypersensitivity - An Overview, Current Allergy & ClinicalImmunology March 2006, VoI. 19, No.1, (histamine and tryptase assays), and Arilmozhi et al, Pharacological Investigations of Sapindus trifoliatus in various in vitro and in vivo models of iflammation, Indian Journal ofPharmacology, vol. 37:2, 96402 (2005) (5-ipoxygenase (5-LO), cyclo oxygenase (COX), Leukotrine B4 (LTB4) and nitric oxide synthase (NOS)). Further, in viva assays of inflammation may be useful in evaluating the peptides utility as a therapeutic against toxic agents. In vivo assays, including, but not limited to, murine EAE models, those utilizing transgenic mice such as MTDBiosciences DSS IBD marine model of severe colitis, the MDfioscience 'fNBS IBD murine model of inflammatory bowel disease, models involving IL 1 knockout mice disclosed within U.S. Patent No. 6,437,216, or models of transgenic mice involving TNF-a as disclosed within Probert et at Spontaneous inflammatory demyelinating disease in transgenic mice showing CNS-specific expression of tumor necrosis factor a.

C. Cancer. The isolated peptides to be used within the method of the current invention may be demonstrated to inhibit tumor cell proliferation, cell transformation and tumorigenesis in vitro or in vivo using a variety of assays known in the art, or described herein. Such assays can use cells of a cancer cell line or cells from a patient. Many assays well-known in the art can be used to assess such survival and/or growth; for example, cell proliferation can be assayed by measuring Hthymidine incorporation, by direct celi count, by detecting changes in transcription, translation or activity of known genes such as proto-oncogenes (eug. fos, rnyc) or cell cycle markers (Rb, cdc2, cyclin A, Dl, D2, D3 or E). The levels of such protein and mRNA and activity can be determined by any method well known in the art. For example, protein can be quantitated by known immunodiagnostic methods such as Western blotting or immunoprecipitation using commercially available antibodies (for example, many celH cycle marker antibodies are from Santa Cruz, Inc.). mRNA can be quantitated by methods that are well known and routine in the art, for example by northern analysis, RNase protection, the polymerase chain reaction in connection with the reverse transcription, etc Cell viability can be assessed by using trypan-blue staining or other cell death or viability markers known in the art Differentiation can be assessed visually based on changes in morphology, etc. The present invention provides for cell cycle and cell proliferation analysis by a variety of techniques known in the art, including but not limited to the following: As one example, bromodeoxyuridine ("BRDU") incorporation Tmay be used as an assay to identify proliferating cells- The BRDU assay identifies a cell population undergoing DNA synthesis by incorporation of BRDU into newly synthesized DNA. Newly synthesized DNA may then be detected using an anti-BRDU antibody (see Hoshino et at 1986, IntJ Cancer 38, 369; Campana et al., 1988, J. Immunol. Meth. 107, 79). Cell proliferation may also be examined using ( 3 H)-thymidine incorporation (see e.g., Chen, J., 1996, Oncogene 13:1395 403; Jeoung, J., 1995, J, Biol. Chem. 270:18367 73), This assay allows for quantitative characterization of S-phase DNA synthesis. In this assay, cells synthesizing DNA will incorporate 3 H-thyrnidine into newly synthesized DNA. Incorporation may then be measured by standard techniques in the art such as by counting of radioisotope in a 78 Scintillation counter (e.g. Beckman LS 3800 Liquid Scintillation Counter) Detection of proliferating cell nuclear antigen (PCNA) may also be used to measure cel proliferation PCNA is a 36 kilodalton protein whose expression is elevated in proiferating cells, particularly in early G! and S phases of the cell cycle and therefore may serve as a marker for proliferating cells. Positive cells are identified by immunostaining using an anti-PCNA antibody (see Li etal 1996, Curr Biot 6:189 199; Vassiiev et at, 1995,1 Cell Se 108:1205 15). Cell proliferation may be measured by counting samples of a cell population over time (e.gs daily cell counts). Cells may be counted using a hemacytometer and light microscopy (eg., HyLite hemnacytometer, Hausser Scientific) Cell number may be plotted against time in order to obtain a growth curve for the population of interest. In a preferred embodiment, cells counted by this method are first mixed with the dye Trypan-blue (Sigma), such that living cells exclude the dye, and are counted as viable members of the population. DNA content and/or mitotic index of the cells may be measured, for example, based on the DNA ploidy value of the cell. For example, cells in the G phase of the cell cycle generally contain a 2N DNA ploidy value. Cells in which DNA has been replicated but have not progressed through mitosis (e.g., cels n S-phase) will exhibit a ploidy value higher than 2N and up to 4N DNA content. Ploidy value and cell-cycle kinetics may be further measured using propidur iodide assay (see e g., Turner, T., et al, 1998, Prostate 34:175 81). Alternatively, the DNA ploidy may be determined by quantitation of DNA Feulgen staining (which binds to DNA in a stoichiometric manner) on a computerized microdensitometrystaining system (see e.g., Bacus, S., 1989, Am I. Pathol. 135:783 92), In another embodiment, DNA content may be analyzed by preparation of a chromosomal spread (Zabalou, S., 1994, Hereditas. 120:127 40; Pardue, 1994, Meth. Cell Biol. 44:333 351) The expression of cell-cycle proteins (elg. CycA, CycB, CycE, CycD, cdc2, Cdk4l/6, Rb, p21 or p27) provide crucial information relating to the proliferative state of a cell or population of cells. For example, identifiation in an anti-proliferation signaling pathway may be indicated by the induction ofp2lcipl. Increased levels of p21 expression in cells results in delayed entry into G, of the cell cycle (Harper et at, 1993, Cell 75:805 816; Li el at, 1996, Curr Biol 6:189 199). p 2 1 induction may be identified by immunostaining using a specific anti p21 antibody available commercially (eg., from Santa Cruz, Inc) Similarly, cell-cycle proteins may be examined by Western blot analysis using commercially available antibodies. In another embodiment, cell populations are synchronized prior to detection of a cell cycle protein. Cell 79 cycle proteins may also be detected by FACS (fluorescence-activated cell sorter) analysis using antibodies against the protein of interest. Detection of changes in length of the cell cycle or speed of cell cycle may also be used to measure inhibition of cell proliferation by a peptide of the Invention. In one embodiment the length of the cell cycle is determined by the doubling time of a population of cells (e.g, using cells contacted or not contacted with one or more peptide of the Invention). In another embodiment, FACS analysis is used to analyze the phase of cell cycle progression, or purify Gl, S, and G2/M fractions (see e.g. Delia, D. et al. 1997, Oncogene 14:2 137 47). Lapse of cell cycle checkpoint(s), and/or induction of cell cycle checkpoint(s), may be examined by the methods described herein, or by any method known in the art Without limitation, a cell cycle checkpoint is a mechanism which ensures that a certain cellular events occur in a particular order. Checkpoint genes are defined by mutations that allow late events to occur without prior completion of an early event (Weinert, T., and IHartwell, L, 1993, Genetics, 134:63 80), Induction or inhibition of cell cycle checkpoint genes may be assayed, for example, by Western blot analysis, or by immunostaining, etc. Lapse of cell cycle checkpoints may be further assessed by the progression of a cell through the checkpoint without prior occrrence of specific events (e.g. progression into mitosis without complete replication of the genomic DNA). In addition to the effects of expression of a particular cell cycle protein, activity and post-translational modifications of proteins involved in the cell cycle can play an integral role in the regulation and proliferative state of a cell. The invention provides for assays involved detected post-translational modifications (e.g, phosphorylation) by any method known in the art. For example, antibodies that detect phosphorylated tyrosine residues are commercially available, and may be used in Western blot analysis to detect proteins with such modifications In another example, modifications such as myristylation, may be detected on thin layer chromatography or reverse phase hplc. (see eg., Glover, C. 1988, Biochem J. 250:485 91; Paige, L., 1988, Bioche ; 250:485 91) Activity of signaling and cell cycle proteins and/or protein complexes is often mediated by a kinase activity. The present invention provides for analysis of kinase activity by assays such as the histone HI assay (see e.g., Delia, D. er al., 1997, Oncogene 14:213747). The peptides used within the method of the Invention can also be demonstrated to alter cell proliferation in cultured cells in viro using methods which are well known in the art. Specific examples of cell culture models include, but are not limited to, for lung cancer, primary rat lung tumor cells (Swafford e at, 1997, McA. Cell, Biol', 17:1366 1374) and large-cell 80 undifferentiated cancer cel lines (Mabry et al., 1991, Cancer Cells, 3:53 58); colorectal cell lines for colon cancer (Park and Gazdar, 1996, £ Cell Biochen. Supply. 24:131 141); multiple established cell lines for breast cancer (-ambly et al, 1997, Breast Cancer Res. Treat. 43:247 258; Gierthy et al, 1997, Chemosphere 34 1495 1505; Prasad and Church, 1997, Bichem Biophys. Res. Commn.a 232:14 19); a number of well-characterized cell models for prostate cancer (Webber et al, 1996, Prostate, Part 1, 29:386 394; Part 2, 30:58 64; and Part 3, 30:136 142; Boulikas, 1997, Anricancer Res. 17:1471 1505); for genitourinary cancers, continuous hurnan bladder cancer cell lines (Ribeiro e al., 1997, nt i Radiat. Blol. 72: 11 20); organ cultures of transitional cell carcinomas (Booth et at., 1997, Lab Invest. 76:843 857) and rat progression models (Vet et a.,1997, Biochimn. Biophys Acta 1360:39 44); and established cell lines for leukemia and Jymphomas (Drexler, 1994, Letl Res. 18:919 927, Tohyamna, 1997, In. J Hematol 65:309 317). The peptdes of the Invention can also be demonstrated to inhibit cell transformation (or progression to malignant phenotype) in vitro. In this embodiment, cells with a transformed cell phenotype are contacted with one or more peptides of the Invention, and examined for change in characteristis associated with a transformed phenotype (a set of in vitro characteristics associated with a tumorigenic ability in vivo), for example, but not limited to, colony formation in soft agar, a more rounded cell morphology, looser substratum attachment, loss of contact inhibition, loss of anchorage dependence, release of proteases such as plasminogen activator, increased sugar transport decreased serum requirement, or expression of fetal antigens, etc. (see Luria et al., 1978, General Virology, 3d Ed., John Wiley & Sons, New York, pp. 436446). Loss of invasiveness or decreased adhesion may also be used to demonstrate the anti-cancer effects of the peptides used in the method of the Invention. For example, a critical aspect of the formation of a metastatic cancer is the ability of a precancerous or cancerous cell to detach from primary site of disease and establish a novel colony of growth at a secondary site. The ability of a cell to invade peripheral sites is reflective of a potential for a cancerous state. Loss of invasiveness may be measured by a variety of techniques known in the art including, for example, induction of E-cadherinmediated cell-e-ell adhesion.|Such E-cadherin-mediated adhesion can result in phenotypic reversion and loss of invasiveness (Hordijk et al, 1997, Science 278:1464 66). Loss of invasiveness may further be examined by inhibition of cell migration. A variety of 2-dimensional and 3-dimensional cellular matrices are commercially available 81 (Calbiochem-Novabiochem Corp. San Diego, Calif). Cell migration across or into a matrix may be examined by microscopy, time-lapsed photography or videography, or by any method in the art allowing measurement of cellular migration. In a related embodiment, loss of invasiveness is examined by response to hepatocyte growth factor (HGF). HGF-induced cell scattering is correlated with invasiveness of cells such as Madin-Darby canine kidney (MDCK) cells. This assay identifies a cell population that has lost cell scattering activity in response to HGF (Hordijk et at, 1997, Science 278:1464 66). Alternatively, loss of invasiveness may be measured by cell migration through a chemotaxis chamber (NeuroprobeiPrecision Biochemicals Inc. VancouverBC), In such assay, a chemo-attractant agent is incubated on one side of the chamber (e.g, the bottom chamber) and cells are plated on a filter separating the opposite side (e.g., the top chamber). In order for cells to pass from the top chamber to the bottom chamber, the cells must actively migrate through small pores in the filter. Checkerboard analysis of the number of cells that have migrated may then be correlated with invasiveness (see e.g., Ohnishi, T., 1993, Biochem Biophys. Rs. Commnn. 193:518 25) The peptides used in the method of the Invention can also be demonstrated to inhibit tumor formation in vivo A vast number of animal models of hyperproliferative disorders, including tumorigenesis and metastatic spread, are known in the art (see Table 317-1, Chapter 317, 'Principles of Neopiasia," in Harrison's Principles of Internal Medicine, 13th Edition, Isselbacher et atl eds, McGraw-Hill, N.Y. p. 1814, and Lovejoy et al 1997 Pathol 181 :30 135). Specific examples include for lung cancer, transplantation of tumor nodules into rats (Wang et al. 1997, Ann. Thorac. Surg64:216 219) or establishment of lung cancer metastases in SCID mice depleted of NK cells (Yono and Sone, 1997, Gan To Kagaku Ryoho 24:489 494); for colon cancer, colon cancer transplantation of human colon cancer cells into nude mice (Gutman and Fidler, 1995 World Surg. 19:226 234), the cotton top tamarin model of human ulcerative colitis (Warren, 1996, Aliment Pharmaco. Their. 10 Supp 12:45 47) and mouse models with mutations of the adenomatous polyposis tumor suppressor (Polakis, 1997, Biochin. Biophys. Aca 1332:F127 F147); for breast cancer, transgenic models of breast cancer (Dankort and Muller, 1996, Cancer Treat. Res 83:71 88; Amundadittir et al., 1996, Breast Cancer Res. Treat, 39:119 135) and chemical induction of tumors in rats (Russo and Russo. 1996, Breast Cancer Res. Treat. 39:7-20); for prostate cancer, chemically-induced and transgenic rodent models, and human xenograft models (Royai et a!., 1996, Semin. Onco-. 23:35 40); for genitourinary cancers, induced bladder neoplasm in rais and mice (Oyasu, 1995, Food 82 Chem. Toxicol 33:747 755) and xenografts of human transitional cell carcinomas into nude rats (Jarrett al, 1995, J Endourot 9:1 7); and for hematopoietic cancers, transplanted alIogeneic marrow in animals (Appelbaum, 1997, Leukemia II (Suppi. 4):S15 517). Further, general animal models applicable to many types of cancer have been described, including, but not restricted to, the p53-deficient mouse model (Donehower, 1996. Semin. Cancer BioL 7:269 278), the MN mouse (Shoemaker ea al, 1997, Biochem. Biophys Aca, 13321F25 F48), and immune responses to tumors in rat (Frey, 1997, Methods, 12:173 188). For example, a peptide to be used in the method of the Invention can be administered to a test animal, in one embodiment a test animal predisposed to develop a type of tumor, and the test animal subsequently examined for a decreased incidence of tumor formation in comparison with an animal not administered the peptide of the Invention. Alternatively, a peptide of the Invention can be administered to test animals having tumors (e.g, animals in which tumors have been induced by introduction of' malignant, neoplastic, or transformed cells, or by administration of a carcinogen) and subsequently examining the tumors in the test animals for turnor regression in comparison to animals not administered the peptide of the Invention. 8. THERAPEUTIC USE A. Modulation of Mediators of the Body's Response One of ordinary skill in the art would recognize that the peptides of the current invention may be used to modulate the effects of the body's response to a disease or disorder associated with tissue damage. In partcular one example of mediators the peptides noted above may be used to modulate are inflammatory modulatorsincluding but not limited to, plasma derived inflammatory mediators,such as bradykinins, C3, C5a, Factor XII, membrane attack complex, Hageman factor, plasmin, thrombin, iymphokines (macrophage activating factor (MAF), macrophage migration inhibition factor (MMIF), macrophage chemotactic factor (MCF), leukocyte migration inhibition factor (LMIF), histamine releasing factors (HRFs), and transfer factor (F)); interleukins (IL-I, IL-2, IL1, IL-4 .. IL-I5); Tumor necrosis factors (TNF-a (cachecin), TNF-p (lymphotoxin)); Interferons (IFN-ri, IFN-, IEN-y IFNo IEN); Colony stimulating factors (granulocyte colony stimulating factor (G-CSF), granulocyte macrophage colony stimulating factor (GM-CSE), macrophage colony stimulating factor (M CSF), and multi colony stimulating factor (IL3)); polypeptide growth factors (acidic fibroblast growth factor (aFGF), basic fibroblast growth factor (bFGF), epidermal growth factor (E); nerve growth factor (NGF), platelet-derived growth factor (PDGE), and vascular endothelial growth factor (VEGF)); Transforming growth factors (TGF-a and TGF-ji), cs-Chemokines (IL-8 83 neutrophil-activating protein 2 (NAP-2), platelet factor-4 (PF-4), and p-thromboglobulin (DTG)); p-Chemokines (monocyte chemoattractant protein I (MCP- ), MCP-3, MIP-la, macrophage inflammatory protein 3i (MIP-4 ), regulated upon activation normal T expressed and presumably secreted chemokine (RANTES)) and Stress proteins (heat shock proteins (HSPs), glucose related proteins (GSPs), ubiquitin, and superoxide dismutase (Mn)), leukemia inhibitory factor (LIF), oncostatin (OSM), ciliary neurotrophic factor (CNTF), platelet basic protein (PBP), lysosome granules, histamine, serotonin, leukotriene B4, nitric oxide, and/or prostaglandins. In a preferred embodirent the peptides inhibit or surpress the activity of te mediators and more preferably inhibit the activity of TNF-a, histamine, nitric oxide, and interleukins. Most preferably, the peptides inhibit the activity of two or more inflammatory mediators. B. Treatment or Prevention of Various Diseases, Disorders, and Conditions The tissue protective peptides and peptide analogs of the current invention are also useful as therapeutics for treatment or prevention of various diseases, disorders, and conditions. One skilled in the art would also recognize that such peptides and peptide analogs can be used to achieve modulation of a tissue protective receptor complex, e.g., tissue protective cytokine complex. Both in vitro and in vivo techniques that can be used for assessing the therapeutic indications ofA for example, the compounds identified by the inventive assays disclosed above are disclosed in PCT Application No. PCT/USOI/49479, U.S. Patent Application Nos. 10/18,905 and 10/185,841 The aforementioned tissue protective peptides and peptide analogs of the invention may be useful generally for the preventiontherapeutic treatment, or prophylactic treatment of human diseases or disorders of the central nervous system or peripheral nervous system which have primarily neurological or psychiatric symptoms, ophthamic diseases, cardiovascular diseases, cardiopulmonary diseases, respiratory diseases, kidney, urinary and reproductive diseases, bone diseases skirt diseases, connective tissue diseases, gastrointestinal diseases and endocrine and metabolic abnormalities. Examples of use include, but are not limited to, protection against and repair of injury resulting from trauma and resulting inflammation to the brain (ischemic stroke, blunt trauma. subarachnoid hemorrhage), spinal cord (ischemia, blunt force trauma), perpheral nerves (sciatic nerve injury, diabetic neuropathy, carpal tunnel syndrome), retinal (macular edema, diabetic retinopathy, glaucoma), and heart (myocardiad infarct, chronic heart failure). In particular, such diseases, disorders, and conditions include hypoxic conditions, which adversely affect responsive tissues, such as excitable tissues 84 including, but not limited to, those noted above in Section 4 2 (xiii), or those responsive cels tissues or organs, those that express the appropriate Type-I cytokine receptor, e g., EPO-R receptor or the tissue protective receptor complex. Therefore, the tissue protective peptides and peptide analogs of the invention can be used to treat or prevent damage to responsive tissue resulting from hypoxic conditions in a variety of conditions and circumstances. Nonimiting examples of such conditions and circumstances are provided in the table herein below. The tissue protective peptides and peptide analogs are also of interest in the modulation of stem cell activity It has been established that cytokines exhibiting tissue protective activity, e~g EPO, are able to mobilize stem cells, stimulating the migration to regions of injury and aiding the repair process, e.g. in a regenerative role. For example, in experimental stroke, EPO mediates the migration of neuroblasts into a region of ischemic injury to regenerate neurons during the period of recovery (Tsai et al, J Neurosci (2006) 26:1269-74). As another example, EPO and carbanylated EPO (CEPO) mobilize endothelial progenitor celIs from the bone marrow into the circulation, These cells then home to distance regions and are involved in the formation of new blood vessels (for effect of EPO, see, Bahlmann et al, 2003, Kidney In!. 64:1648-1652). While not wishing to be bound to any particular theory, the isolated peptides and peptide analogs disclosed herein are believed to have a similar effect on the migration of stem cells. In the example of the protection of neuronal tissue pathologies treatable and preventable using tissue protective peptides and peptide analogs of the invention, such pathologies include those which result from reduced oxygenation of neuronal tissues. Any condition which reduces the availability of oxygen to neuronal tissue, resulting in stress, damage, and finally, neuronal cell death, can be treated using tissue protective peptides and peptide analogs of the present invention. Generally referred to as hypoxia and/or ischemia, these conditions arise from or include, but are not limited to, stroke, vascular occlusion, prenatal or postnatal oxygen deprivation, suffocation, choking, near drowning, carbon monoxide poisoning, smoke inhalation, traumaincluding surgery and radiotherapy asphyxia, epilepsy, hypoglycenia, chronic obstructive pulmonary disease, emphysema, adult respiratory distress syndrome, hypotensive shock, septic shock, anaphylactic shock, insulin shock, sickle cell crisis, cardiac arrest, dysrhythmia, nitrogen narcosis, hypoxemic hypoxia (altitude sickness, high altitude pulmonary edema, high altitude cerebral edema, sleep apnea, hypopnea, respiratory arrest, shunts), methaemoglobinaeria, histotoxic hypoxia, intrauterine hypoxia, and neurological deficits caused by heart-lung bypass procedures. 85 In one embodiment, for example, the tissue protective peptides and peptide analogs of t present invention identified using the above-noted assays could be administered alone or as part of a composition to prevent injury or tissue damage resulting from risk of injury or tissue damage prior to, during, or subsequent to a surgical procedure or a medical procedure. For example, surgical procedures may include tumor resection or aneurysm repair and medical procedures may include labor or delivery. Other pathologies caused by or resulting from hypoglycemia which are treatable using tissue protective peptides and peptide analogs of the present invention include insulin overdose, also referred to as iatrogenic hyperinsulinemia, insulinoma growth hormone deficiency, hypocortisolisin, drug overdose, and certain tumors. Other pathologies resulting from excitable neuronal tissue damage include seizure disorders, such as epilepsy, convulsions, or chronic seizure disorders. Other treatable conditions and diseases include, but are not limited to, diseases such as stroke, multiple sclerosis, hypotension, cardiac arrest, chronic heart failure, Alzheimer's disease, Parkinson's disease, cerebral palsy, brain or spinal cord trauma, AIDS dementia, age-related loss of cognitive function, memory loss, amyotrophic lateral sclerosis, seizure disorders, alcoholism, retinal ischemia, optic nerve damage resulting from glaucoma, and neuronal loss The specific tissue protective peptides and peptide analogs of the present invention may be used to treat or prevent inflammation resulting from disease conditions or various traumas, such as physically or chemically induced inflammation The tissue protective peptides and peptide analogs are also contemplated for the treatment and prevention of inflammatory conditions in one or more organs or tissues including, but not limited to, the brain, spinal cord, connective tissue, heart, lung, kidney and urinary tract, pancreas, eyes and prostate. Non-limiting examples of such trauma include, hut are not limited to those listed in Section 4.2 (xvi). Further the tissue protective peptides may used to treat or prevent inflammation resulting from ischemic and non-ischemic conditions including, but not limited to, allergies, allergic diseases, alergic symptoms, rheumatic diseases, sports related injuries, exposure to toxic agents, infections including viral, fuingal, and bacterial, further examples of such conditions are disclosed above in Section 4.2(iv), (v) and (xvi). The inflammation may be acute or chronic. Further applications in the field of inflammation are noted within PCT/US2004/03 1789 filed September 29, 2004 and published as WO 2005/032467. The specific tissue protective peptides and peptide analogs of the present invention may be used to treat central nervous and peripheral nervous system diseases resulting from demyelination or impairment of the mylin sheath. These diseases are defined as mainly 86 involving inflammatory myelin sheath lesions of unknown origin, with the exception of myelination deficiency diseases, such as leukodystrophy, and diseases due to obvious causes. Multiple sclerosis (MS) is a typical disease among demyelinating diseases, and pathologically, it is characterized by changes, mainly, inflammatory demyeiination. and gliosis. Since its etiology is unknown, its diagnosis is made based on its clinical features, i.e., spatial multiplicity and multiplicity over time of central nervous system lesions. Furthermre, acute disseminated encephalomyelitis (ADEM), inflammatory diffuse sclerosis, acute and subacute necrotizing hemorrhagic encephalomyelitis, and transverse myelitis are included in demyelinating diseases. Also, peripheral nervous tissues rely upon Schwann cells to maintain the myelin sheathif these cells are impaired, peripheral demyelinating disease is caused. The tissue protective peptides and peptide analogs of the present invention may be used to treat or prevent conditions ot, and damage to the heart including any chronic or acute pathological event involving the heart and/or associated tissue (e.g., the pericardium, aorta and other associated blood vessels), including ischemia-reperfusion injury; congestive heart failure; cardiac arrest; myocardial infarction; atherosclerosis, mitral valve leakage, atrial flutter, cardiotoxicity caused by compounds such as drugs (e.g, doxorubicin, herceptin, thioridazine and cisapride); cardiac damage due to parasitic infection (bacteria, fungi, rickettsiae, and viruses, eg, syphilis, chronic Trypanosoma cruzi infection); fulminant cardiac amyloidosis; heart surgery; heart transplantation; angioplasty, laparoscopic surgery, traumatic cardiac injury (e.g, penetrating or blunt cardiac injury, and aortic valve rupture), surgical repair of a thoracic aortic aneurysm; a suprarenal aortic aneurysm; cardiogenic shock due to myocardial infarction or cardiac failure; neurogenic shock and anaphylaxis. The tissue protective peptides and peptide analogs of the current invention may also be used to treat those individuals at risk for heart disease such as cardiac failure (ie where the heart is not able to pump blood at a rate required by the metabolizing tissues, or when the heart can do so only with an elevated filling pressure) Such at risk patients would include patients having or being at risk of having cardiac infarction, coronary artery disease, myocarditis, chemotherapy, cardiomyopathy, hypertension, valvular heart diseases (most often mitralnsufficiency and aortic stenosis) and toxininduced cardiomyopathy (e g. ethanol, cocaine, etc.) and the like. The tissue protective peptides and peptide analogs of the present invention may be used to treat or prevent conditions of, and damage to, the eyes, e g., retinal tissue. Such disorders include, but are not limited to retinal ischemia, macular degeneration, retinal detachment, retinitis pigmentosa, arteriosclerotic retinopathy, hypertensive retinopathy, retinal artery blockage, retinal vein blockage, retinal edema, hypotension, and diabetic retinopathy. In another embodiment, the tissue protective peptides and peptide analogs of the present invention and principles of the invention may be used to prevent or treat injury resulting from exposure to toxic agents, i.. radiation or chemical damage to responsive tissue. In one embodiment of the invention the above-noted peptides are useful as therapeutics for modulating the mediators of the body' response to toxic agents, preferably to suppress or inhibit the activity of such modulators. Additionaly, the above-noted peptides are useful as therapeutics for the treatment, prevention, amelioration or management of damage, effects or symptoms of exposure to a toxic agent. The peptides may be used to treat exposure to various toxic agents, including biological, chemical or radiation agents. These peptides may be used to treat the damages, effects, or symptoms due to biological agents such as of prions, virus microorganisms (bacteria and fungi), and some unicellular and multicellular eukaryotes (i.e., parasites), including, but not limited to, those biological toxins listed above in Section 42(viii).

Further, one of ordinary skill in the art will recognize that the peptides may also be used to prevent, mediate, treat or amelorate the damages, effects or symptoms due to the cumulative or synergistic use of these toxic agents (i.e., the use of a radioactive agent prior to dispersing a biological agent so that the victim's will be more susceptible to the biological agent, administering a vesicant agent in conjunction with a nerve agent to prevent the victims from effectively seeking refuge or aid, tainting bullets or shrapnel with biological or radioactive agents to inhibit or complicate the healing process, etc.) '88 Preferably, peptides of the current invention will be able to treat, mediate, ameliorate or prevent toxic effects on several different types of cells, organs, or tissues for example in two or more of the following central nervous,peripheral nervous, ophthalmic, cardiovascular, cardiopulmonary, respiratory, kidney, urinary, reproductive, musculoskeletl, skin, connective tissue, gastrointestinal, hematopoietic, endocrine, and metabolic. Further, a peptide of the current invention would be effective as a therapeutic or preventive for more than one toxic agent within the same class (i e against more than one type of chemical, biolocalal or radioactive agent a preventive against a vesicant and nerve agents for example)or different classes of toxic agents (i.e. a therapeutic for exposure to a radioactive agent and a chemical agent). A further utility of the tissue protective peptides and peptide analogs of the present invention is in the treatment of poisoning, such as neurotoxin poisoning (e.g., domoic acid shellfish poisoning), toxins (ethanol, cocaine, etc. as the result of chemotherapeutic agents of radiation exposure; neurolathyrism; Guam disease; amyotrophic lateral sclerosis; and Parkinson's disease. As mentioned above, the present invention also provides tissue protective peptides and peptide analogs of the present invention for use in enhancing tissue function in responsive cells, tissues and organs in a mammal by peripheral administration of a tissue protective peptide as described above. Various diseases and conditions are amenable to treatment using this method. For example this method is useful for enhancing function in excitable tissues resulting in an increase in cognitive fnction even in the absence of any conditon or disease. Further, the tissue protective cytokines are useful for improving the quality of wound healing, reducing the time required to heal, improving the quality of the healed tissues and reducing the incidence of adhesions resulting from the wound. See PCT/US2004/03 1789 filed September 29, 2004 and pubished as WO 2005/032467, Further the tissue protective peptides of the current invention may be useful in treating, preventing or managing the lesions on the skin or along the respiratory pathways induced by chemical agents such as blistering or vessicant agents or industrial chemicals. These uses of the peptides of the present invention are describe in further detail below and include enhancement of learning and training in both human and non-human mammals. In another embodiment, the tissue protective peptides and peptide analogs of the present invention nay be useful generally for the prevention, therapeutic treatment, prophylactic treatment or management of various cancers or neoplastic disorders of the central nervous system, peripheral nervous system, gastrointestinal/digestive system, genitourinary system, 89 adrenal, gynecological, head and neck, hematologica/blood, musculoskeletasoft tissue, respiratory, and breast. Examples of use include, but are not limited to, protection against and repair of injury resulting from cancers or neoplastic disorders listed in section 4.2(ix) and (xxv). Further the peptides of the current invention may be used for the prevention, therapeutic treatment, prophylactic treatment or management of various syndromes associated with neoplasms or cancers, including, but not limited to those listed above in Section 4.2 (xxviii). The peptides may be used in accordance with the method of the current invention to address the above-noted syndromes. For example, the peptides may be administered to address hereditary syndromes such as Li Fraumeni, hereditary nonpolyposis colorectal cancer, familial adenomatous polyposis, and Von Hippel-Lindau syndrome by either delaying the onset of the neoplastic aspects of the disease; reducing the number of neoplastic growths associated with the syndrome, or in general enhancing the quality of life or the longevity of those patients afflicted with these conditions. The peptides may also be administered prophylactically to address syndromes related to certain treatment, chemotherapy or radiation therapy, of the neoplastic disorder or cancer, such as androgen deprivation syndrome, therapy related myeiodysplastic syndrome or somnolence syndrome, in the hopes of preventing the syndromes or reducing the severity of the syndrome. Further, the peptides may be used to treat or prevent cachexia and diseases related to cachexia. Such diseases include, but are not limited to cancer cachexia, anorexia, asthenia, anemia, tuberculosis, AIDS, congestive heart failure, renal failure, liver failure, chronic obstructive pulmonary disease, emphysema, muscle atrophy, diabetes, and endotoxinemia, Conditions and diseases treatable or preventable using tissue protective peptides and peptide analogs of the present invention provides the central nervous system include but are not limited to mood disorders, anxiety disorders, depression, autism, attention deficit hyperactivity disorder, and cognitive dysfunction. These conditions benefit from enhancement of neuronal function. Other disorders treatable in accordance with the teachings of the present invention include sleep disruption, for example, sleep apnea and travel-related disorders; subarachnoid and aneurismal bleeds, hypotensive shock, concussive injury, septic shock, anaphylactic shock, and sequelae of various encephalitides and meningitides, for example connective tissue disease-related cerebritides such as lupus. Other uses include prevention of or protection from poisoning by neurotoxins, such as domnoic acid shellfish poisoning, neurolathyrism, and Guam disease, amyotrophic lateral sclerosis, Parkinson's disease; 90 postoperative treatment for embolice or ischemic injury; whole brain irradiation; sickle cell crisis; and eclampsia A further group of conditions treatable or preventable using tissue protective peptides and peptide analogs of the present invention include mitochondrial dysfunction, of either a hereditary or acquired nature, which are the cause of a variety of neurological diseases typified by neuronal injury and death. For example, Leigh disease (subacute necrotizing encephalopathy) is characterized by progressive visual loss and encephalopathy, due to neuronal drop out, and myopathy. In these cases, defective mitochondrial metabolism fails to supply enough high energy substrates to fuel the metabolism of excitable cells. A tissue protective peptide or peptide analog optimizes failing function in a variety of mitochondrial diseases. As mentioned above, hypoxic conditions adversely affect excitable tissues. The excitable tissues include, but are not limited to, neuronal tissues such as tissue of the peripheral nervous system (ear and retina) and central nervous system (brain and spinal cord); cardiovascular tissue such as the ce!ls of the heat and associated nerves; and glandular tissue such as the pancreas where T type calcium channels along with cell-to-cell gap junctions participate in secretion of insulin. An exemplary list of excitable tissue includes, but is not limited to, organs and tissues that include nerves, skeletal muscle, smooth muscle, cardiac muscle, uterus, central nervous system, spinal cord, brain, retina, olfactory system, and auditory system, In addition to the conditions described above, the tissue protective peptides and peptide analogs of the present invention are useful in the treatment of inhalation poisoning such as carbon monoxide and smoke inhalation, severe asthma, adult respiratory distress syndrome, and choking and near drowning. Further conditions which create hypoxic conditions or by other means induce responsive tissue, such as excitable tissue damage include hypoglycemia that may occur in inappropriate dosing of insulin, or with insulin-producing neoplasms (insulinoma). Various neuropsychologic disorders which are described to originate from excitable tissue damage are treatable using tissue protective peptides and peptide analogs of the present invention. Chronic disorders in which neuronal damage is involved and for which treatment or preventable by the present invention include disorders relating to the central nervous system and/or peripheral nervous system including age-related loss of cognitive function and senile dementia, chronic seizure disorders, Alzheimer's disease, Parkinson's disease, dementia, memory loss, amyotrophic lateral sclerosis, multiple sclerosis, tuberous sclerosis, Wilson' disease, cerebral and progressive supranuclear palsy, Guam disease, Lewy body dementia, prion diseases, such as spongiform encephalopathies, e.g., Creutzfeldt- Jakob 91 disease, Huntington's disease, myotonic dystrophy, Freidrich's atax<ia and other ataxias, as well as Cilles de La Tourette's syndrome, seizure disorders such as epilepsy and chronic seizure disorder, stroke, brain or spinal cord trauma, AIDS dementia, alcoholism, autism, retinal ischemia, glaucoma, autonomic function disorders such as hypertension and sleep disorders, and neuropsychiatric disorders that include, but are not limited to schizophrenia, schizoaffective disorder, attention deficit disorder, dysthymic disorder, major depressive disorder, mania, obsessive-compulsive disorder, psychoactive substance use disorders, anxiety, panic disorder, as well a unipolar and bipolar affective disorders Additional neuropsychiatric and neurodegenerative disorders include, for example, those listed in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM), A further group of conditions treatable or preventable using tissue protective peptides and peptide analogs of the present invention include kidney diseases such as renal failure, acute and chronic. Blood supply to the kidneys can be cut off due to several causes including shock from infections invading the bloodstream (septicemia), internal or external hemorrhaging, loss of fluid from the body as a result of severe diarrhea or bums, reactions to transfusions, cardiac arrest or arythmias, surgical trauma and kidney transplantations. The reduced flow of blood to the kidneys resulting from the above conditions may reduced blood flow to dangerously low levels for a time period great enough to cause the development of acute renal failure. The depressed blood flow also results in necrosis, or tissue deathin the kidney, damaging the renal tubular cels. Renal failure may also result from diseases (interstitial and diabetic) nephrotic syndromes, infections, injury (CPB-induced), toxins (contrast-induced, chemotherapy-induced, cyclosporine), autoimmune inflammation (eg Lupus, erythrocytosis etc.) The tissue protective peptides and peptide analogs of the current invention assist in the repair or prevention of this damage helping to ameliorate acute renal failure. Further, the peptides of the current invention may be used to treat, prevent or ameliorate diseases or disorders of the urinary tract including, but not limited, urinary tract infections, irritable bladder, and trauma or radiation injury to the bladder. The following table lists additional exemplary, non-limiting indiations as to the various conditions and diseases amenable to treatment by the aforementioned tissue protective peptides and peptide analogs.

Such compositions will 106 contain a therapeutically effective amount of the compound, preferably in purified fr, together with a suitable amount of carrier so as to provide the form for proper administration to the patient. The formulation should suit the mode of administration. Formulations for increasing transmucosal adsorption of peptides such as long acting peptides are also contemplated by the current invention. Pharmaceutical compositions adapted for oral administration may be provided as capsules or tablets; as powders or granules; as solutions, syrups or suspensions (in aqueous or non-aqueous liquids); as edible foams or whips; or as emulsions. Tablets or hard gelatine capsules may comprise lactose, starch or derivatives thereof, magnesium stearate, sodium sacnharine, cellulose, magnesium carbonate, stearic acid or salts thereof. Soft gelatin capsules may comprise vegetable oils, waxes, fats, semi-solid, or liquid polyols etc. Solutions and syrups may comprise water, polyols and sugars. An active agent intended for oral administration may be coated with or admixed with a material that delays disintegration and/or absorption of the active agent in the gastrointestinal tract (e~g., glyceryl monostearate or glyceryl distearate may be used), Thus, the sustained release of an active agent may be achieved over many hours and, if necessary, the active agent can be protected from being degraded within the stomach. Pharmaceutical composions for oral administration may be formulated to facilitate release of an active agent at a particular gastrointestinal location due to specific pH or enzymatic conditions. Pharmaceutical compositions adapted for transdermal administration may be provided as discrete patches intended to remain in intimate contact with the epidermis of the recipient for a prolonged period of time. Pharmaceutical compositions adapted for topical administration may be provided as ointments, creams, suspensions, lotions, powders, solutions, pastes, gels, sprays, aerosols or oils. For topical administration to the skin, mouth, eye or other extemal tissues a topical ointment or cream is preferably used. When formulated in an ointment the active ingredient may be employed with either a paraffinic or a water-miscible ointment base. Altematively, the active ingredient may be formulated in a cream with an oil-in-water base or a water-in-oil base. Pharmaceutical compositions adapted for topical administration to the eye include eye drops. In these compositions, the active ingredient can be dissolved or suspended in a suitable carrier, e.g. in an aqueous solvent. Pharmaceutical compositions adapted for topical administration in the mouth include lozenges, pastilles and mouthwashes. Pharmaceutical compositions adapted for nasal and pulmonary administration may comprise solid carriers such as powders (preferably having a particle size in the range of 20 to 500 microns). Powders can be administered in the manner in which snuff is taken, ie. by 107 rapid inhalation through the nose from a container of powder held close to the nose. Alternatively, compositions adopted for nasal administration may comprise liquid carriers, eg, nasal sprays or nasal drops. Alternatively, inhalation of compounds directly into the lungs may be accomplished by inhalation deeply or installation though a mouthpiece into the oropharynx.

In one embodiment, an autoinjector comprising an injectable solution of a peptide may be provided for emergency use by ambulances, emergency rooms, and battlefield situations, and even for self-administration in a domestic setting, particularly where the possibility of traumatic amputation may occur, such as by imprudent use of a lawn mower. The lkelihood that cells and tissues in a severed foot or toe will survive after reattachment may be increased by administering a peptide to multiple sites in the severed part as soon as practicable, even before the arrival of medical personnel on site, or arrival of the afflicted individual with severed toe in tow at the emergency room In a preferred embodiment, the composition is formulated in accordance with routine procedures as a pharmaceutical compositiofl adapted for intravenous administration to human beings. Typically, compositions for intravenous administration are solutions in sterile 108 isotonic aqueous buffer. Where necessary, the composition may also include a solubilizing agent and a local anesthetic such as lidocaine to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water-free concentrate in a hermetically-sealed container such as an ampule or sachette indicating the quantity of active agent. Where the composition is to be administered by infusion, it can be dispensed with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the composition is administered by injection, an ampule of sterile saline can be provided so that the ingredients may be mixed prior to administration. Suppositories generally contain active ingredient in the range of 0.5% to 10% by weight; oral formulations preferably contain 10% to 95% active ingredient. A perfusate composition may be provided for use in situ perfusion Such pharmaceutical compositions may comprise levels of peptides, or a form of peptides not suitable for acute or chronic, local or systemic administration to an individual, but will serve the functions intended herein in as an organ bath, organ perfusate, or in situ perfusate prior to removing or reducing the levels of the peptide contained therein before exposing or returning the treated organ or tissue to regular circulation. The invention also provides a pharmaceutical pack or kit comprising one or more containers filled with one or more of the ingredients of the pharmaceutical compositions of the invention. Optionally associated with such container(s) can be a notice in the form prescribed by a governmental agency regulating the manufacture, use or saie of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration. In another embodiment, for example, a peptide can be delivered in a controlled release system. For example, the peptide may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. in one embodiment, a pump may be used (see Langer, supra; Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al., 1980, Surgery 88:507; Saudek et al., 1989, N. Engl. J. Med. 321:574, each of which is incorporated by reference hereinn i its entirety). In another embodiment, the compound can be delivered in a vesicle, in particular a liposome (see Langer, Science 249:1527-1533 (1990); Treat a., in Liposones in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); WO 91/04014; U.S. Patent No. 4,704,355; Lopez-Berestein, ibid, pp. 317-327; see generally ibid.). 109 In another embodiment, polymeric materials can be used (see Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Press: Boca Raton, Florida, 1974; Controlled Drug Bioavaiability, Drug Product Design and Performance, Smolen and Ball (edsj Wiley: New York (1984); Ranger and Peppas, Macromo Sci Rev. Macromol. Chem. 23:61, 1953; see also Levy et at 1985, Science 228:190; During et al., 1989, Ann, Neurol. 25:351; Howard et a., 1989, . Neurosurg. 71:105, (each of which is incorporated by reference herein in its entirety)} In yet another embodiment, a controlled release system can be placed in proximity of the therapeutic target, ie, the target cells, tissue or organ, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, pp. 115-138 in Medical Applications of Controlled Release, vol. 2, supra 1984, which is incorporated by reference herein in its entirety). Other controlled release systems are discussed in the review by Langer (1990, Science 249: 1527-1533, which is incorporated by reference herein in its entirety). In another embodiment, peptide, as properly formulated, can be administered by nasal. bucal, oral, rectal, vaginal, ocular, transdermal, parenteral, inhalation or sublingual administration. In a specific emodiment, it may be desirable to administer a peptide of the invention locally to the area in need of treatment; this may be achieved by, for example, and not by way of limitation, local infUsion during surgery, topical application, eg.n conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by neans of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as silastic membranes, or fibers. A nondimiting example of such an embodiment would be a stent or other scaffolding coated with a peptide of the present invention implanted in a portion of the vasculature, duct, et. Selection of the preferred effective dose will be readily determinable by a skilled artisan based upon considering several factors, which will be known to one of ordinary skill in the art. Such factors include the particular form of peptide, and its pharmacokinetic parameters such as bioavailability, metabolism, half-life, etc. which will have been established during the usual development procedures typically employed in obtaining regulatory approval for a pharmaceutical compound. Further factors in considering the dose include the condition or disease to be treated or the benefit to be achieved in a normal individual, the body mass of the patient, the route of administrationwhether administration is acute or chronic, concomitant medications, and other factors well known to affect the efficacy of administered pharmaceutical 110 agents. Thus the precise dosage should be decided according to the judgment of the practitioner and each patient's circumstances, e.g., depending upon the condition and the immune status of the individual patient, and according to standard clinical techniques. in another aspect of the invention, a perfusate or perfusion solution is provided for perfusion and storage of organs for transplant, the perfusion solution includes an amount of a peptide or peptide analog effective to protect responsive cells and associated cells, tissues or organs.

In a further embodiment, the perfusate solution contains from about I to about 500 ng/ml of a peptide, or from about 40 to about 320 ng/ml peptide. As mentioned above, any form of peptide can be used in this aspect of the invention. While the preferred recipient of a peptide for the purposes herein throughout is a human, the methods herein apply equally to other mammals, particularly domesticated animals, livestock, companion, and zoo animals. However, the invention is not so limiting and the benefits can be applied to any mammal. In farther aspectsof the ex-vivo invention, any peptide such as but not limited to the ones described above may be employed. In another aspectof the invention, methods and compositions for preventing, treating or managing a disease or disorder associated with tissue damage or damage, effects or I Il symptoms resulting therefrom in cells, tissues or organs which are not isolated from the vasculature by an endothelial cell barrier are provided by exposing the cells, tissue or organs directly to a pharmaceutical composition comprising a peptide, or administering or contacting a pharmaceutical composition containing a peptide to the vasculature of the tissue or organ. Similar to other tissue protective compounds based on erythropoietin, it is possible that the peptides of the present invention may be transported from the luminal surface to the basement membrane surface of endothelial cells of the capillaries of organs with endothelial cell tight junctions, including, for example, the brain, retina, and tests. Thus, the effects of a disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom on cells across the barrier may be treated. While not wishing to be bound by any particular theory, after transcytosis of the peptide may interact with a tissue-protective receptor on a cell, for example, neuronal, eye (eg., retinal), adipose, connective, hair, tooth, mucosal, pancreatic, endocrine, aural, epithelial, skin, muscle, heart, lung, liver, kidney, small intestine, adrenal (e.g. adrenal cortex, adrenal medulla), capillary, endothelial, testes, ovary, stem or endometrial cell, and receptor binding can initiate a signal transduction cascade resulting in the activation of a gene expression program within the responsive cell or tissue, resulting in the protection of the cell or tissue, or organ, from damage, such as by exposure to a toxic agent, inflammation, hypoxia, etc. In another embodiment, the peptide can be cross-linked to a compound that can cross the barrier, such as CEPO, to be transported across the barrier in accordance with the teaching of PCT Application No. PCT/USO1/49479, U.S. Patent Application Nos. 10/188,905 and 10/185,841, incorporated herein by reference Thus, methods for protecting a tissue from disease or disorder associated with tissue damage or damage, effects or symptoms resulting therefrom are described in detail herein below In the practice of one embodiment of the invention, a mammalian patient is undergoing systemic chemotherapy for cancer treatment, including radiation therapy, which commonly has adverse effects such as nerve, lung, heart, ovarian or testicular damage. Administration of a pharmaceutical composition comprising a tissue protective peptide or peptide analog as described above is performed prior to and during chemotherapy and/or radiation therapy, to protect various tissues and organs from damage by the chemotherapeutic agent, such as to protect the testes. Treatment may be continued until circulating levels of the chemotherapeutic agent have fallen below a level of potential danger to the mammalian body. 112 In the practice of another embodiment of the invention, various organs are planned to be harvested from a victim of an automobile accident for transplant into a number of recipients, some of which required transport for an extended distance and period of time. Prior to organ harvesting, the donor is infused with a pharmaceutical composition comprising tissue protective peptides and peptide analogs as described herein. Harvested organs for shipment are perfused with a perfusate containing tissue protective peptides or peptide analogs as described herein, and stored in a bath comprising tissue protective peptides or peptide analogs. Certain organs are continuously perfused with a pulsatile perfusion device, uilizing a perfusate containing tissue protective peptides and peptide analogs in accordance with the present invention. Minimal deterioration of organ function occurs during the transport and upon implant and reperfusion of the organs in situ. In another embodiment of the present invention, a participant in a hazardous activity that exposes the individual to toxic agents, one could take a dose of a pharmaceutical composition containing a peptide sufficient to either prevent (i.e. delaying the onset of, inhibiting, or stopping), protect against, or mitigate the effects of exposure to a toxic agent. In particular, this method of treatment may have application in various professions involving contact with toxic agents, such as miners, chemical manufacturers, military personnel (soldiers, paratroopers), emergency personnel (police, fire, EMS, and disaster relief personnel), construction workers, food processors, and employees at power reactors. In another embodiment of the invention, a surgical procedure to repair a heart valve requires temporary cardioplegia and arterial occlusion. Prior to surgery, the patient is infused with a tissue protective peptide or peptide analog. Such treatment prevents hypoxic ischemic cellular damage, particularly after reperfusion. Additionally, the pharmaceutical compositions of the present invention may be used prophylactically to prepare an individual for surgery in an effort to limit the trauma associated with the surgical procedure or aide in the recovery of the individual from the surgical procedure. Although the present method of treatment using pharmaceutical compositions containing tissue protective peptides and peptide analogs provide a prophylactic use for surgical procedures, it may be particularly useful in procedures that induce temporary ischemic events including, but not limited to, bypass procedures (coronary bypass), angioplasty procedures, amputations, and transplantations, as well as, those performed directly upon responsive cells, tissues, or organs such as brain and spinal cord surgery, and open heart procedures, Such procedures may involve the use of cardiopulmonary (bear lung) bypass. I13 In another embodiment of the invention, in any surgical procedure, such as in cardiopulmonary bypass surgery, a tissue protective peptide or peptide analog of the invention can be used. In one embodiment, administration of a pharmaceutical composition comprising tissue protective peptides and peptide analogs as described above is performed prior to, during, and/or following the bypass procedure, to protect the function of brain, heart, and other organs. In the foregoing examples in which a peptide is used for ex-vivo applications, or for in vivo applications to treat a disease or disorder associated with tissue damage or damages, effects or symptoms resuming therefrom, the invention provides a pharmaceutical composition in dosage unit form adapted for prevention, treatment or management of the damages and effects of exposure to a toxic agent or symptoms thereof which comprises an amount within the range from about .01 pg to 30 mg, .5 pg to 25 mg, I pg to 20mg, 500 pg to 10mg, i ng to 10 mg, 500 ng to 10mg, 1 pg to 10 mg, 500 ug to 10 mg, or I mg to 10 mg ofa peptide, and a pharmaceutically acceptable carrier. In a preferred embodiment, the amount of peptide is within the range from about .5 pg to I mg. In a preferred embodiment, the formulation contains peptides that are non-erythropoietic. Furthermore, this restorative aspect of the invention is directed to the use of any peptides herein for the preparation of a pharmaceutical composition for the restoration of cellular, tissue or organ dysfunction, wherein treatment is initiated after, and well after, the initial insult responsible for the dysfunction. Moreover, treatment using peptides of the invention can span the course of the disease or condition during the acute phase as well as a chronic phase. A peptide of the invention may be administered systemically at a dosage between about I ng and about 300 pg /kg body weight, preferably about 5 -150 pig /kg-body weight, most preferably about 10-100 g kg-body weight, per administration. For example, administration may be repeated hourly, daily, as long as clinically necessary, or after an appropriate interval, e.g., every 1-12 hours, preferably every 6 to 12 hours; every 2-6 days, preferably every 2-4 days; every I to 12 weeks, preferably, every I to 3 weeks. In one embodiment, the effective amount of peptide and a pharmaceutically acceptable carrier may be packaged in a single dose vial or other container. In another embodiment, the peptides, which are capable of exerting the activities described herein but not causing an increase in hemoglobin concentration or hematocrit, are used. Such peptides are preferred in instances wherein the methods of the present invention are intended to be provided chronically. 114 EXAMPLES EXAMPLE 1: METHOD OF PEPTIDE SYNTHESIS. A. Synthesis of Peptide A (SEQ ID NO:2, corresponding to EPO amino acid sequence 38-57) and Peptide B (SEQ ID NO:3, corresponding to EPO amino acid sequence 58 Peptide A, SEQ ID NO:2, and Peptide B, SEQ ID NO:3, fragments of EPO, were synthesized using "in situ neutralization" Boc Chemistry stepwise solid-phase peptide synthesis, as described in Band, D,. Chopra, N and Kent, S., "Total Synthesis of Crambin," JAM CHEM SOC. 2004, 126, 1377-1383 (incorporated by reference herein in its entirety). Briefly, two fragments corresponding to EPO amino acid sequence 38-57 (peptide A, NITVPDTKVNFYAWKRMEVG SEQ ID NO:2) and EPO amino acid sequence 58-82 (peptide B, QQAVEVWQGLALLSEAVLRGQALLV, SEQ ID NO:3) were synthesized on -OCH-Pam resins (free 'carboxyl peptides) or on HSCH 2

CH

2 CO-Leu-OCH-Pam-Resin ("thioester peptides). During synthesis the side chains of various amino acids were protected as follows: Arg(Tos), Asn(Xan), Asp(OcHex), Cys(4-CH 3 Bzl) or Cys(ACM), Glu(OcHex), Lys(2-Cl-Z), Ser(Bzl), Thr(Bzl), Tyr(Br-Z). After the peptide chain was assembled, the peptides were deprotected and simultaneously cleaved from the resin support by treatment with anhydrous HF containing p-cresol (90:10, v/v) for I hr at 0 'C. After evaporation of the HF under reduced pressure, crude products were precipitated and triturated with chilled diethyl ether and the peptides were dissolved in 50% aqueous acetonitrile containing 0.1% TFA and purified by the preparative HPLC system. Peptide compositions were confirmed using LC-MS. Peptide ID (UEQLERALNSS, SEQ ID NO: 282) is an 11-amino acid linear peptide with a protected N-terminus (by the 5 membered ring structure of pyrogiutamic acid) and a free carboxyl group at the C-terminus. Its molecular weight is 1257 Daltons. It was synthesized using standard Fmoc solid phase peptide synthesis on Wang resin, purified by preparative HPLC and ion-exchange chromatography, and lyophiized. Acetate and arnmonium are bound in ionic form to basic and acidic groups of the peptide molecule forming a mixed salt. EXAMPLE 2. TISSUE PROTECTIVE PEPTIDES AND PEPTIDE ANALOGS ARE NON-ERYTHROPOIETIC. A. In Vitro Assessment 115 UT-7epo, a human erythropoietin-dependent leukemia cell line, was used for the determination of the erythropoietic potency of the peptides. UT-7epo cells (Deutsche Sammlung von Mikroorganismen und Zeilkulturen (DSMZ), Cat. No. ACC 363) are grown in a complete RPMIT. 1640 medium with 10% FBS and 5 ng/ml erythropoietin. The proliferation/survival (= viability increase) response of the cells exposed to erythropoietin is mediated by the classical erythrocyte-type erythropoietin receptor and is a quantitative measure of the capacity of erythropoietin- variants to stimulate the classical erythropoietin receptor. UT-7epo cells were transferred to fresh complete RPMI 1640 medium containing 10% donor calf serum, 4 mM L-glutanine, and supplemented with 5 ng/mI of recombinant human erythropoietin. The cells were maintained in 75 cm 2 flasks with 20 ml of medium/flask in a humidified incubator with 5% CO 2 at 371C for 48 h. On day two of the assay, i e., at 48 h, the cells were transferred from the flask into a 50-mi conical tube and centrifuged at 1,000 rpm for 5 minutes at room temperature, The supernatant was discarded and the cells were washed two times with 10 ml of starvation media (3% donor calf serum, 4 mM L-glutamine). The cells were then re-suspended in starvation media, using up and down pipette action to obtain a single cell suspension, The re-suspended cells were diluted with starvation media to obtain a density of 4 x 10 5 cells/mL, and plated at a total culture volume of 10 mi per 25 cm 2 flask. Following a 4 h incubation, the cells were again transferred to a 50-ml conical tube, Control cells were maintained throughout with 5 ng/ml of rhu-erythropoietin. Cells were diluted to 200,000 cells/mI in starvation medium, plated at 100 p/well in a 96 well plate and exposed to varying concentrations of erythropoietin, and Peptide ID, SEQ ID NO:282. A series of 10 fold dilutions in RPM! 1640 medium containing 3% serum was used to generate concentrations of test compounds from 5 pM to 50 nM. Following a further for 48 h incubation, a solution of 15 ml WST-I Cell Proliferation Reagent (Roche) was added to each well, and incubated for 1 hour at 37 'C in CO 2 . After mixing for I minute, the plate was read in a plate reader (absorption at 450 an, subtracted from background absorption at 650 nm). As shown in FIG. I, Peptide ID had no erythropoeitic activity over the range of doses in comparison to the strong erythropoietic effect of EPO. This was well below the expectation that a non-erythropoietic peptide or peptide analog will have no erythropoietic activity for a dose lower than I sg/ml, and more preferably for a dose lower than 10 pg/mI. B. In Vivo Assessment 116 To evaluate the erythropoietic activity of tissue protective peptides and peptide analogs, Peptide ID was administered intravenously twice a day to Sprague Dawley rats for 28 days. Nine male and nine female rats were assigned to groups 1-4 receiving 0, 60, 180, and 600 pg/kg per dose (0, 48, 143, and 477 nmol/kg, respectively) of Peptide ID in PBS by bolus intravenous administration from days 1-28, Blood samples to assay for hematological variables were collected on day 29. Hemoglobin concentration was determined by use of an automated analyzer (Keska Corporation). As shown in FIG. 2, there was no difference in any of the groups in hemoglobin concentrations. Further the erythropoietic and hematopoietic affects of Peptide ID were evaluated in rabbits. Blood sampics were take of all rabbits prior to the initiation of the study to eatablish the hematological baseline for the animals. Peptide ID was administered twice daily i.v to New Zealand White rabbits for 28 days. For this study, six males and females were assigned to groups I and 4, and four males and four females were assigned to groups 2 and 3. Group 1 received 0, group 2 received 30 pg (24 nmol/kg bw), group 3 received 90 pg/kg (72 nmol/kg bw); and group 4 received 300 pg/kg (240 nmol/kg bw) per dose Peptide ID in PBS by bolus iLv. administration. Blood samples to assay for hematological variables were collected on day 29. Comparison of baseline vs. day 29 hematological parameters showed no difference in hemoglobin concentration, hematocrit, or platelet count (FIG 3, a. b, and c.). EXAMPLE 3. PEPTIDE OR PEPTIDE ANALOG IS TISSUE PROTECTIVE IN IN VITRO ASSAYS. Peptides and peptide analogs can be readily assessed for tissue protection using any number of in vitro assays. For example, protection from excitoxicity can be determined using kainite-induced death of mouse motoneurons. Spinal cords were obtained from 15 -day old Sprague-Dawley rat embryos as previously described (Siren et al., 2001, Proc. NazI. Acaed Sci. USA, 98:4044, hereby incorporated by reference in its entirety). The ventral horn was trypsinized and centrifuged through a 4% BSA cushion for 10 min at 300 X g. Cells (representing mixed neuron-glia culture) were seeded at a density of 2,000 cells/cm into 24-mm well plates precoated with poly-DL ornithine and laminin. Motoneurons were further purified by immunopanning and the cells were seeded at low density (20,000 cells/cm 2 ) onto 24-mm well plates precoated with poly-DL-ornithine and laminin, and containing complete culture medium [Neurobasal/B27 (2%); 0.5 mM L-glutamine; 2% horse serum; 25 mM 2 mercaptoethanol; 25 mM glutamate; 1% penicillin and streptomycin; I ng/ml BDNF}. The medium (without 117 glutamate) was re-added to cultures on days 4 and 6. Cell death was induced on day 6 in culture by incubation for 48 h with kainic acid (5 mM for mixed neuron-glia cultures; 50 mM for purified cultures). Peptide B (5ng/mL, 1.8 nM), EPO (3.3 nM) or vehicle was added to the cultures 72 h before induction of cell death, and treatment continued for 48h. The medium was then discarded and the cells were fixed with 4% (vol/vol) paraformaldehyde in PBS for 40 min, permeabilized with 0.2% Triton X-100, were blocked with 10% (vol/vol) FCS in PBS, were incubated with antibodies against non-phosphorylated neurofilaments (SMI-32; 1:9,000) ovemight, and were visualized by using the avidin-biotin method with diaminobenzidine. Viability of motoneurons was assessed morphologically by counting SMI-32 positive cells across four sides of the cover slip and staining for apoptotic bodies was done by using H33258. As shown in FIG. 4, Peptide B protected the cells against the neurotoxic effects of the glutamate receptor agonist kainic acid. EXAMPLE 4. MIDDLE CEREBRAL ARTERY OCCLUSION MODEL. Sprague Dawley rats (8 per group) are subjected to the following MCAO protocol Surgery was performed in accordance with the teachings of Brines et a!, 2000, PNAS USA 97:10526-10531 (hereby incorporated by reference in its entirety. Briefly, the rats are anesthetized with chloral hydrate (400 mg/kg-bw, i.p,), the carotid arteries were visualized, and the right carotid was occluded by two sutures and severed. A burr hole adjacent and rostral to the right orbit allowed visualization of the middle cerebral artery ("MCA"), which was cauterized distal to the rhinal artery. To produce a penumbra (border zone) surrounding this fixed MCA lesion, the contralateral carotid artery was occluded for I hour by using traction provided by a fine forceps and then re-opened. The rats were administered saline, Peptide ID as a single iv. dose (2 tg/kg bw), or Peptide IX, LSEQARNQSEL, SEQ ID NO: 301) a scrambled version of Peptide B, SEQ ID NO: 3, as a single iv. dose (2 ig/kg bw) upon reperfusion, followed by three additional injections at 2-hour intervals. For assessment of injury, rats are subjected to behavioral testing or the volume of the lesion is determined by tetrazolium staining of brain sections performed 24 hours post surgery in accordance with the previously noted protocol. (a) Volume of lesion. 118 The volume of the lesion was then determined by tetrazoliun staining of brain sections performed 24 hours post surgery. Peptide ID demonstrated a significant reduction in infaret volume at 24 hours (225 ± 20 mm 3 ) in comparison to saline treated rats (291 ± 23 m 3 ), (biBehavioral testin Rats were also tested in a foot fault behavioral protocol. Rats were tested on an elevated stainless steel grid floor 30 cm x 30 cm with grid size of 30 mm according to the protocol of Markgraf et c., 1992, Brain Research 575:238-246 (hereby incorporated by reference in its entirety). When placed on the grid, a rat would attempt to move around and occasionally place a foot, rather than on the grid, through a grid opening ("foot fault"). The number of foot faults was measured for a 1 minute period. The number of foot faults is indicative of the cognitive impairment of the rats due to the MCAO, the fewer the number of foot faults the less cognitive impairment. As shown in FIG. 5, Peptide ID significantly improved the rats performance in the foot fault protocol (11.2+ 1. 1 foot faults) in comparison to the saline treated rats (20.2 + 0.8 foot faults) and Peptide IX treated rats (20.1 + 2.1 foot faults). EXAMPLE 5: BILATERAL RENAL ISCHEMIA ASSAY Sixty male C57/BL6 mice (~25 g; Charles River Laboratories) were anesthetized with ketamine (150 mg&g) and xylazine (15 mg/kg) i.p. Each animal was placed on a honmeothermic blanket set at 37" C, and after a mid-line laparotomy, the renal pedicles were clamped for 30 minutes using nontraumatic vascular clamps. Peptide ID was administered at the indicated dose via i.p. Injection at 1 minute, 6 hours, and 12 hours after reperfusion. In a single dose study, the mice received a control (PBS), 1 pg/kg of Peptide IG at 1 minute, I pig/kg of Peptide IG at 30 minutes, 1 g/kg of Peptide ID at 6 hours, or 10 pg/kg of Peptide ID at 6 hours (12 mice per group). In a multiple dose study, the mice received received either multiple doses of a control (PBS), 0.1 ig/kg of Peptide ID, I jig/kg of Peptide ID, or 10 jig/kg of Peptide ID at I minute, 6 hours and 12 hours into reperfusion. Twenty-four hours later, mice were reanesthetized and blood was obtained by cardiac puncture. Plasma urea and creatine were used as indicators of renal dysfunction and aspartate aminotransferase was used as an indicator of renal injury. Data were analyzed using ANOVA followed by Dunnets post hoc test comparison. 119 As shown in FIG 6 and FIG. 7As shown in each graph, 1 pg/kg of Peptide ID or 10 pag/kg of Peptide ID resulted in a reduction in these biochemical markers of renal dysfunction. EXAMPLE 6: WOUND HEALING A full thickness punch biopsy model of wound healing was used to evaluate Peptide ID In this experiment, 3.5 mm-diameter full-thickness skin wounds were placed at the comers of a 3 cm-wide square on the shaved and depilated scapular region of Sprauge-Dawley rats. Peptide ID (24 nmol/kg of bw, 9 rats) or PBS (9 rats) was administered subcutaneously daily for 10 days. The area of open wound, measured in a blinded fashion from serial digital photographs, exhibited faster healing in the animals that received Peptide ID as shown in FIG. 8. EXAMPLE 7: ENHANCEMENT OF COGNITION A novel object recognition paradigm in rats was used to evaluate their recall of previously experienced objects. Specifically, adult Wistar rats were exposed to novel test objects and then reexposed to them 24 hours later. Animals were divided into 5 groups receiving either : (l)vehicle, (2) galantamine (3 mg/kg i.p.) I hr before testing as a positive control, (3) Peptide ID (24 nmolfkg bw i.p.) 3 hours after the first exposure to the novel objects, (4) Peptide ID (24 nmoukg bw ip.) twice daily for 5 days before training and continued through the day immediately after training, and (5) Peptide ID (24 nmol/kg bw i.p.) I hour before first exposure to the novel object. As shown in FIG. 9, the rats from groups 2-4 exhibited improved recognition of the novel objects in the test in comparison to the rats in groups I and 5. These results suggest that Peptide ID may influence the consolidation phase of memory acquisition. EXAMPLE 8: CISPLATIN INDUCED NEPHROPATHY Cancer chemotherapeutic agents such as cisplatin (CDDT) are known to induce renal injury among other toxicities. The ability of Peptide IC to protect rats form cisplatin-induced nephropathy was evaluated by administering 2 mg/kg CDDT intraperitoneally, twice a week for 5 weeks. Peptide IC was simultaneously administered at a dose of 0.4 ag/kg, three times a week for 5 weeks. Renal function was evaluated by measuring the volume of urine production. As 120 shown in FIG. 10, concurrent treatment with Peptide IC protected against renal dysfunction due to CDDT. Also, CDDT is known to induce peripheral neuropathy, among other toxicities. Following the experimental design described above for renal function,the ability of Peptide IC to protect against peripheral neuropathy was also evaluated. 2 mg/kg CDDT was administered intraperitoneally, twice a week for 5 weeks. Peptide IC was simultaneously administered at a dose of 0.4 pg/kg, three times a week for 5 weeks. Neuropathy was evaluated by hotplate latency, the delay period between contact of the rats foot to a warm surface, and the retraction of the foot. As shown in FIG. 11, concurrent treatment prevented the appearance of peripheral neuropathy EXAMPLE 9: CORTICAL TUMOR IMPLANT. A cortical tumor implant study was conducted in accordance with the protocol of Lampson et al. Cancer Res. 53:176-82:1993 to determine the effect of Peptide ID on the growth of the tumor. In accordance with the protocol, male CD fisher rats were anesthetized and their right scalp was shaved and washed with disinfectant. A small incision was then made in the scalp overlying the right temporal cerebral cortex. A 1mm hole was drilled through the calvarium, without puncturing the dura matter. Under aseptic conditions, living 50,000 9L/LacZ gliosarcoma cells in 5 pl was slowly injected through a 22 gauge needle attached to a precision Hamilton syringe. Bone wax was then applied to the trephanation site, the skin was sutured and a prophylactic dose of antibiotic was administered i.p. Control rats were provided with saline injections i p. daily. The rats treated with Peptide ID received daily injections of 30 pg/kg i.p. daily for a period of 25 days. At 25 days following implantation, the animal was anesthetized and the brain perfused-fixed with 2% paraformaldehyde. The brain was then removed and cut on a brain matrix device into coronal sections 1 mm thick and the extent of tumor mass was determined by planimetric methodology. FIG. 12 demonstrates that Peptide ID inhibited the further growth of the cortical tumor in this model. Whereas the relative volume of the tumor in the saline treated rats grew to greater than 0.4 cm2, the tumors in the Peptide ID treated rats experienced no growth in the tumor volume. 121 EXAMPLE 10: 9L GLIOSARCOMA IMPLANTATION MODEL. In accordance with the accordance with the protocol of Lampson et al. Cancer Res. 53:176-82:1993 described above, CD Fisher rats were implanted with 9L gliosarcoma cells transfected with the LacZ gene by use of a Hamilton syringe. 100,000 cells in 10 microliters were injected into the right caudate. Two weeks after implantation, animals were divided into three groups for daily intraperitoneal injections: one receiving a Peptide ID with a short plasma half life, another receiving Peptide 1W (pegylated form of Peptide IC) and the third group received saline. Peptides were given at a dose of 25 nmole/kg body weight. Three weeks later, the animals were sacrificed and serial I mm thick coronal sections cut through the brain and incubated with 5 bromo-4-chloro-3-indolyl-[beta]- D-galactopyranoside (Xgal). Tumor cells (containing the LacZ gene) metabolized Xgal into a dark blue stain, localizing the extent of tumor. High resolution digital images were obtained and the areas stained blue determined using pianimetric methodology. Data is expressed as total area of tumor infiltration. Results, as represented in FIG. 13, show a marked reduction in tumor size in the group treated with the peptide with longer half life (Peptide 1W) to a total area equal to that obtained when animals were treated daily with the peptide with shorted half life (Peptide ID) begun on the day of implantation and continued daily until sacrifice. In contrast, while the mean area of the group that received the shorter acting peptide (Peptide ID) at two weeks after implantation was smaller than the saline group, it was not significantly different. Further, FIG.14, presents comparative photos of the brains of the saline, Peptide ID, and Peptide IW treated rats. As can be clearly seen the largest tumor (dark area) is present in the saline treated rats. The rats treated with Peptide ID daily had substantially smaller tumors, however the rats treated with Peptide 1W after two weeks exhibited the best outcomes. These findings are consistent with the ability of peptides to cause the regression of the 9L gliosarcoma cell line. EXAMPLE 11: (PROPHETIC TREATMENT IN CANCER CACHEXIA. The ability of the peptides to address cachexia symptomatic of cancer may be verified by the following protocol. 122 Rats weighing about 200g would be inoculated intraperitoneally with 103 AH 130 Hepatoma cells. Simultaneously, one group of rats would be treated with a peptide of interest such as, Peptide ID or Peptide IW, at a dose that would be in a therapeutically effective range, about .10 to 2.0 pg/kd/day. A second group would be treated with a placebo. On day 16, the rats would be sacrificed. The food intake and locomotor activity of the subject rats would be assessed before inoculation and on day 11. The weight and body composition would be evaluated by NMR-scan on day 0 and day 16 after sacrifice. In comparison to the placebo treated rats, one would expect those treated with a peptide in accordance with the method of the current invention to exhibit less fat and lean mass wasting. In addition, the food intake and locomotor activity of the peptide treated rats would be improved. EXAMPLE 12: HISTAMINE INDUCED EAR INFLAMMATION. The ability of peptides useful in the current therapeutic method to antagonize the pro-inflammatory affects of histamine were evaluated in a mouse model of histamine-induced edema disclosed in Brand et al. "Tea tree oil reduces histamine-induced oedema in murine ears," Inflamm, Res. 51 (2002) 283-289. Briefly, 24 Sprague Dawley rats (male, 250 gi) were used in the study. Prior to the histamine challenge, each rat was anesthetized and the thickness of the rat's ear was measured using a spring loaded micrometer. 20 ul of 60 mg/mI solution of histamine diphosphate was injected intradermally into an ear of the rat and 30 seconds later the rat received either (1) 30 pg/kg Peptide ID IV (12 rats) or (2) Saline IV (12 rats). Then 20 ul of 60 mg/mI solution of histamine diphosphate was injected intradermally to the rat's other ear. The thickness of the rats ears was then measured using a caliper at 15, 30, 45 and sixty minutes following the histamine challenge. As can be seen in FIG. 15, Peptide ID reduced the amount of edema associated with the histamine challenge in comparison to saline. EXAMPLE 13: HISTAMINE INDUCED WHEAL FORMATION The ability of Peptide ID to reduce plasma extravasation heala) induced by intradermal histamine administration was evaluated in rats. Animals were pre-administered Evans Blue dye (which binds tightly to albumin) to provide a visual marker of vascular leak. To determine the persistence of peptide IG activity, at various time periods after Peptide ID 123 administration (30 jg/kg, administered intravenously), an intradermal dose of 0.12 pg histamine was administered, and the extent of dye leak quantitated by planimetry performed on digital photographs obtained 15 minutes following histamine placement, a time at which wheal surface area is greatest. Each animal was tested at only a single time point to avoid influence of histamine administration on subsequent responses. Single-dose Peptide ID administration was found to suppress wheal formation, and the suppressive effect was detectable up to 24 hours following a single dose, as shown in FIG. 16, showing the difference in area of saline versus Peptide ID-treated animals, EXAMPLE 14: HISTAMINE INDUCED WHEAL FORMATION Under isoflurane anesthesia, 12 Sprague-Dawley rats' abdomens were shaved and depilated. Each rat was then injected intravenously (via internal jugular) with a dilute solution of Evans Blue (30 mg/mil in saline, I ml/kg bw). After 5 minutes, 6 small doses of histamine (Histamine diphosphate, 20 microliters administered intradermally) in a rectangular patten on each rat's abdomen. After fifteen minutes, when the wheal reaches its maximum size the wheal is photographed and the blister area was determined by digital planimetry. To test the efficacy of various peptides, the peptide of interest was administered to the rats intravenously shortly after the histamine injection. The peptides tested and results are noted below. A. Erythropoietin. Rats received either saline or 10 pgm/kg of EPO at time of histamine challenge FIG. 17 illustrates that the rats that the wheal area (lesion area) of the EPO treated rats (about 4 cm 2 ) was half the lesion area of the saline treated animals (about .8 cm 2 ). B. Peptide ID, Peptide IW, and Scrambled Peptide ID (Peptide IY, SEQ ID NO: 304, GLpLSEARNQSEL). Rats received either saline, Peptide 1Y (30 pg/kg), Peptide ID (30 jig/kg), or Peptide IW (30 pg/kg) at time of histamine challenge. FIG. 18 illustrates that the wheal area (lesion area) of the Peptide ID and Peptide 1W treated rats (about .35 cm 2 and 3 cm 2 respectively) was half the lesion area of the saline and Peptide IY treated animals (about .6 cm 2 each). This not only demonstrated the efficacy of Peptides ID and IW in modulating histamine and the inflammatory response associated with histamine but the importance of the above disclosed motifs to the efficacy of the peptides given that the Peptide TY did not exhibit anti inflammatory activity. 124 C. Peptide 1W, Retro Inverso Peptide IC (Peptide IZ, SEQ ID NO, 300, SSNLAQRELQEQ), Peptide ID, and Scrambled Peptide IZ (Peptide JA (SEQ ID NO. 301) LSEQARNQSEL). Rats received either saline, peptide JA (30 pg/kg), peptide IZ (30 pg/kg), peptide 1W (30 pg/kg) or peptide ID (30 sg/kg) at time of histamine challenge. FIG. 19 illustrates that the wheal area (lesion area) of the peptide IW,ID and IZ treated rats (about .3 cm 2 , .35 cm 2 and .4 cm 2 respectively) was less than the lesion area of the saline and peptide JA treated animals (about .6 cm each EXAMPLE 15: DECUBITUS ULCER ASSAY A decubitus ulcer (pressure sore) assay was performed on 24 adult Sprauge Dawley rats in accordance with the disclosure of Pierce et al., Selective A2A adenosine receptor activation reduces skin pressure ulcer formation and inflammation, Am J Physic! Heart Circ Physio 281:67-74, 2001. Briefly, a ferromagnetic steel plate was implanted under a dorsal region of the rats skin. A rectangular permanent magnet was applied to the area of the skin under which the plate was implanted in order to compress the skin between the plate and the magnet. This compression reduced the flow of blood to the skin causing ischemia. The rats were subjected to a cycle of ischemia-reperfusion (2 hours ischemia with a .5 hour reperfusion) for a 72-hour period. The area of the wound on each rat was measured and, subsequently, the rats were treated with either saline, 30 g/kg Peptide ID administered sc twice: once at the beginning of the first period of ischemia and a second time at 24 hours later, 30 pg/kg Peptide ID administered sc daily, or EPO daily. Daily the area of the wound on each rat was measured for a period of 12 days. FIG. 20 demonstrates that Peptide ID and EPO reduced the size of the wound, and that daily administration of Peptide IG resulted in the smallest wound size. EXAMPLE 16 (PROPHETIC EXAMPLE): SKIN PRICK TEST An initial histamine skin prick test is performed to determine a baseline, The skin prick test is performed on a patient in a semi-recumbent position on the volar aspect of both forearms (more than 5 cm above the distal skin creases of the vrists). The forearm is cleansed with alcohol and allowed to dry. Using a pen, the prospective skin test sites, for histamine and negative control, are marked and label at least 2 cm apart from one another. A drop of histamine dihydrochloride (10 mg/mI) or negative control is placed at the appropriate mark, and then a srile lancet is introduced through each drop at an 90" angle and withdrawn. The sites are then 125 observed for the presence of erythmea and wheal formation at 15 minutes following administration. A photograph is taken of the wheals and then the size of the wheal is determined using digital planimetry. The skin prick test is performed again at a time period of at least 3 hours later using the above protocol. One of the above noted peptides may be administered to the patient at a period of 15 minutes to 2 hours prior to administration of the histamine challenge, at the time of administration of the histamine challenge, or I to 60 minutes following the histamine challenge to determine the ability of the peptide to prevent, manage/ameliorate or treat histamine induced inflammation, respectively. For example, at the time of the histamine prick the patient may be given a dose of Peptide ID by IV or sc injection. It is expected that the wheal area will be about 50% less after treatment with Peptide ID. EXAMPLE 17: RADIOMITIGATING ACTIVITY IN HEMATOPOIETIC SCREENING ASSAY. The ability of peptides useful in the current therapeutic method to mitigate the effects of a radioactive agent on the hematopoietic system was evaluated in a marine model of radiation injury. Briefly, 80 C57BL/6 mice (50% female and 50% male, 15-28 gin) were used in the study were divided into two groups. In both groups the radiation was administered to the mice as a single uniform total body dose of gamma radiation from a mCs radiation source (GammaCell 40; Nordion International, Kanata, Ontario, Canada) at an exposure rate of 65-69 cGy/minute +1- 25 ccy. Group A received a LD70/30 dose of radiation (796 cy) and then 20 of the mice were administered Peptide ID (30 ug/kg subcutaneously) at 24 hrs after irradiation and then once a day for 29 days. The remaining 20 mice (control group) received PBS (subcutaneously) at 24 hrs after irradiation and then once a day for 29 days. Group B received a LD90/30 dose of radiation (831 c(y) and then 20 of the mice were administered Peptide ID (30 ug/kg subcutaneously) at 24 hrs after irradiation and then once a day for 29 days. The remaining 20 mice (control group) received PBS (subcutaneously) at 24 hrs after irradiation and then once a day for 29 days. The mice were monitored for survival once a day until signs of early euthanasia appeared, then twice/day until day 30, As shown in FIG. 21, thirty-day survival and overall survival time of mice receiving Peptide ID administered subcutaneously were significantly increased compared to the 126 mice receiving PBS. In particular, at 796 cGy the treatment mice exhibited a 45% survival rate in comparison to the control group's 0% survival rate, and at 831 cGy the treatment mice exhibited a 20 % survival rate in comparison to the control group's 5% survival rate EXAMPLE 18: RADIOMITIGATING ACTWITY IN A GASTROINTESTINAL SCREENING ASSAY. The ability of peptides useful in the current therapeutic method to mitigate the effects of a radioactive agent on the gastrointestinal system was evaluated in a marine model of radiation injury. Briefly, 30 C57BL/6 mice (male, 20-30 gm) were used in the study. The radiation was administered to the mice using a Pantak I.F320 X-ray (Agfa NDT Ltd., Reading, UK), operated at 300 kV, 10 mA. The X-ray tube has additional filtration to give a radiation quality of 2.3 mm Cu half-value layer (HVL). Mice had their head, thorax, and forelimbs shielded to protect their bone marrow and select for the GI response. The mice were restrained in a jig and positioned at a distance of 700 mm focus from the focus of the X-ray tube. Irradiation was delivered at a dose rate of 75.5 cGy/min (unshielded) and 70.0 cGy/min (shielded) for a period sufficient to expose the mice to 15 Gy of radiation. At 24 hours following radiation, 15 of the mice were administered Peptide ID (30 ug/kg subcutaneously) and then once a day for the duration of the study and remaining 15 mice (control group) received PBS (subcutaneously) and then once a day for the duration of the study. The mice were weighed and monitored once a day until signs of diarrhea and early euthanasia appeared, then twice a day. As shown in FIG. 22, twenty-day survival of mice receiving Peptide ID administered subcutaneously was significantly greater than the mice receiving PBS (6 mice in treatment group vs. 1 in the control group), This invention is not to be limited in scope by the specific embodiments described which are intended as single illustrations of individual aspects of the invention, and functionally equivalent methods and components are within the scope of the invention.
