Background of invention
American more than 1,000,000 suffers from type i diabetes, also is referred to as insulin dependent diabetes mellitus (IDDM) (being abbreviated as IDDM) or juvenile onset diabetes.In type i diabetes, people's pancreas produces and seldom or not produces insulin-a kind of necessary hormone that earns a bare living.Although reason is also not exclusively known, type i diabetes is multifactorial autoimmune disease, and it is to be caused by the specificity of the β cell of insulin-producing in the pancreas and carrying out property destruction.Spend one of the highest chronic disease childhood period that it being, and be the disease that people can't remove forever.Though insulin can make the people be survived, it can not cure diabetes, can not prevent its final and destructive result: renal failure, blind, nerve injury, amputation, heart attack and apoplexy.In order to survive, the people who suffers from type i diabetes must accept repeatedly injection of insulin every day or by pump infusion of insulin constantly, and must sting every day and refer to take a blood sample six times or more times measures their blood glucose.When making great efforts balance injection of insulin and its food ration, the people who suffers from type i diabetes also must prepare always potential hypoglycemia be hypoglycemia and blood glucose too high be that hyperglycemia is reacted, but these reaction life-threatenings.Although strict note keeping fit meals, workout scheme are also always injected an amount of insulin, but many other factorses can influence people's glycemic control unfriendly, this comprise stress, hormone variation, growth cycle, body movement, Drug therapy, illness/infection and fatigue.Even use insulin, type i diabetes also cause the rapid decline of quality of life usually, and make average life shorten 15 years.Annual about 30,000 Americans are diagnosed as suffers from type i diabetes, and wherein surpassing 13,000 people is the child.Just every day 35 children.
Type ii diabetes is also referred to as non-insulin-dependent diabetes mellitus (being abbreviated as NIDDM) or maturity-onset diabetes, and is relevant with the relative shortage of obesity, insulin resistance and insulin usually.Although the diabetes of this form are non-insulin requirements as a rule, exist surprising similarity between it and the type i diabetes.For example, now people are consistent thinks: also exist the absolute shortage of the β cell of insulin-producing in type ii diabetes, this beta cell lacks and is likely because the rate of death increase of beta cell causes.Therefore, generation may can be used as the treatment of I type and type ii diabetes at the pharmacological treatment of the protective effect of beta cell death.

Do embodiment 1: Compound I such as salt I provide protection at beta cell death and diabetes?
In following embodiment, β-TC6 cell is meant the beta-TC6 cell.
Insulin-dependent (I type) diabetes (IDDM) are multifactorial autoimmune diseasees, and it is to be caused by the specificity of the β cell of insulin-producing and carrying out property destruction.Think that the dysfunction and the damage of beta cell are to soak into cell (macrophage, CD4 because of itself and islets of langerhans +Or CD8 +(NK) direct contact T-cell) and/or be exposed to the cytotoxicity medium that these cells produce is as proinflammatory cytokine (IL-1, TNF-α, IFN-γ), free radical, Fas part, TRAIL and perforin.At the autoimmunity of beta cell can by environmental factors such as beta cell toxin, nutritional labeling, stress, initiation such as metabolism over loading, virus.In type i diabetes, possible beta cell participates in the destruction of himself on one's own initiative by outside dead signal is converted into inner cell apoptotic event.The apoptosis and the necrosis of beta cell induced in the combination of proinflammatory cytokine, particularly IL-1 and IFN-γ.Therefore, can imagine that these cytokines not only regulate islets of langerhans and soak into activity of immune cells, and in the pathogenesis of type i diabetes, beta cell be applied direct illeffects.As if stimulate beta cell to cause a plurality of signal conduction incidents with IL-1, comprise the activation of protein kinase (PKC, p38, JNK, ERK, MSK1), lipase (PLC, PLD, sphingomyelinase), cyclo-oxygenase and transcription factor (NF-κ B, ATF-2, c-jun, Elk-1, CREB, cEBP-β, IRF-1, STAT-1).Albumen that is inducible nitric oxide synthase (iNOS) after these incidents and stress be relevant such as hsp70, Heme oxygenase, Mn-SOD, ICE etc. induce.Unfortunately, which change that it be unclear that in the gene expression is essential for the death of beta cell in the type i diabetes.Apoptosis mainly is that response ultraviolet light or DNA repair inhibition and generation in beta cell system.Take place that the p53 tumor suppressor protein is induced before this, the generation of reactive oxygen element, PARP inhibition, S-and G 2-cell cycle is prevented and mitochondrial membrane potential descends.Cytokine mainly promotes necrosis, only promotes apoptosis on less degree, and its activation is repaired inhibition or the identical signal conduction step of ultraviolet light with DNA in fact.According to these experiment in vitro, obviously the dead mode of beta cell can change with the difference of dead signal, and similarly the signal conducting path can be used to realize multi-form beta cell death.
C-Abl is the protein tyrosine kinase of wide expression, and it has the molecular weight of about 145kDa.Under physiological condition, proved that c-Abl participates in regulating cytoskeleton function such as migration and cellularity and cell cycle progression.Yet, when cellular exposure in multi-form stress the time, the c-Abl highly activation that becomes, this causes cell cycle to be prevented and apoptosis.
In sum, the broad research of non-beta cell proved c-Abl to dissimilar stress response in promote apoptosis.The deduction effect of c-Abl in insulin-producing cells do not illustrated as yet.Whether therefore, it be unclear that this albumen plays a role in the selection between beta cell death and apoptosis and necrosis.
Meaning for type i diabetes.Although as if the pathogenesis of type i diabetes very complicated, might cause the interior path of born of the same parents of beta cell death on a certain specified point, to be converged.Imagination ground, this can only adopt a kind of approach to block a plurality of dead signals, realize the probability of beta cell survival thus for we provide.
Tyrosine kinase c-Ab 1 may be a kind of important mediators of beta cell death.C-Abl has expression in bTC-6 cell and isolated rat islets of langerhans, and no matter be to use the pharmacologically active agents Compound I still by knock out with the RNAi technology C-Abl express the C-Abl realized active suppress all to produce at proinflammatory cytokine or nitric oxide donors the protective effect of inductive beta cell death.C-Abl plays a role by promoting nitric oxide to produce, and can not resist the inductive nitric oxide generation of cytokine institute because suppress C-Abl.
Based on these data, the c-Abl conduct stress play a role with the sensor of outside dead signal, and the activation of c-Abl can cause JNK and p38MAP tyrosine phosphorylation and activation, NF-κ B and PI3K inactivation, mitochondrion to discharge short antiapoptotic factors and finally cause beta cell death.Compound I can be blocked different dead signals, realizes the survival of beta cell thus and at the protective effect of diabetes.
The result:In order to determine Compound I such as whether salt I intervenes or whether c-Abl participates in causing the signal transduction cascade of beta cell death, make the isolated rat islets of langerhans be exposed to the nitric oxide donors DETA/NO (0.5mM) of slow release or the combination that is exposed to IL-1 β (25U/ml)+IFN-γ (1000U/ml)+TNF-α (1000U/ml) reaches 24 hours.In both cases, between whole incubation period, all having or do not having under the condition of 10 μ M Compound I such as salt I and cultivate islets of langerhans.After incubation period, islets of langerhans lived with iodate third ingot (propidium iodide)+Bb (bisbenzimide) dye and under fluorescence microscope, take pictures.The percentage ratio of total cell number is counted and be expressed as to (the white shrinkage or the broken nuclear) of apoptosis and downright bad (red or pink broken nuclear) cell.Itself does not influence the viability of islet cells salt I such as Compound I.DETA/NO induces 10% islet cells necrosis, and combination of cytokines is induced about 40% necrosis.It is worth noting that NO donor combined significantly thing I of inductive cell death of institute such as salt I resist (table 1).Equally, the islet cells necrosis of cytokine induction is partly reduced by the c-Abl inhibitor.In all groups, the frequency of apoptotic cell was lower than for 10% (result does not show).

Tested Compound I and whether provide protection at causing the Rezulin streptozotocin external.Under the 0.4mM streptozotocin, described protective effect highly significant, and under the 0.75mM streptozotocin, Compound I only provides weak protective effect (table 2).Under the 0.6mM streptozotocin, the protection effect of Compound I is medium.

Research design and method
1. identify that the path that suppresses by Compound I promotes the other dead signal of people's beta cell death And stressors.With 10uM salt I such as Compound I handler islet cells, and measure the islet cells death that responds following cytotoxic substance: hydrogen peroxide (150 μ M; Oxidative stress), staurosporin (200nM, PKC-suppresses), FCCP (5 μ M; Uncoupling and mitochondrial membrane permeability change), brefeldin A (10 μ M, ER stress), thapsigargin (thapsigargin) (200nM, ER stress with the Ca that increases 2+) and amycin (2 μ M, DNA damage).Dye succeeded by the fluorescence microscopy microscopy by iodate third ingot and Bb work and to come observation of cell death.Use 10 islets of langerhans of two groups.This operation make can to the apoptosis of complete islets of langerhans and downright bad both carry out quantitatively.Described dyeing technique alive and XTT detection method (the MTT detection method of reduced form) combination, this provides the Screening test method of simple and rapid islets of langerhans viability for us.
2. whether the research Compound I influences the development of diabetes in the type i diabetes animal model.As mentioned above, injection provides protection at the single dose streptozotocin for Compound I such as salt I.In order to extend this observed result, estimated the diabetes developing effect of c-Abl at the c57KSJ/ black mouse model of multiple dose streptozotocin processing.The Compound I treatment (the 200mg/kg Compound I in 200 μ l 0.9%NaCl) of every day starts from preceding 1 day of streptozotocin processing first (every day, low dosage 40mg/kg injection was 5 days), and continues 10 days or two weeks, this moment occurs obvious diabetes.By every day the measuring blood value estimate described treatment.After 10 days or two weeks, put to death mice, take out pancreas and fixing to carry out immunohistochemistry and the morphometry credit is analysed.To islets of langerhans inflammation and the score of beta cell amount.
Studied the importance of c-Abl in the palindromia of non-obese diabetes mice (being abbreviated as the NOD mice).Use above given similar scheme.But, in this case, give the Compound I treatment to the female NOD mice of diabetes.By gavage behind the administered compound I 1 day first, will be from young NOD mice isolating 300 islet transplantations under the scrotum.Measuring blood value and put to death mice after 7 days.Point at this moment, the immune cell destruction that most beta cells of transplanting have been activated, Compound I all is detectable to any deduction effect of beta cell survival.Reclaim graft and fixing to analyze.
The 3rd, studied the effect of Compound I to born diabetic duration in the NOD mice.Make the miniature osmotic pumps of the subcutaneous Alzet of acceptance of female NOD mice in age in 4-5 week (this moment not or have minimum insulitis), this osmotic pumps per hour discharges the dense Compound I of 0.25 μ l or independent excipient reached for 4 weeks.Mices are put to death in 4 week backs, take out pancreas and fixing to carry out immunohistochemistry and the morphometry credit is analysed.Degree and the score of beta cell amount to insulitis.
The pharmacology who considers c-Abl suppresses the problematic probability of possibility, has attempted the gene approach.For this purpose, from c57/KSJ black and NOD mice, separate islets of langerhans, disperse islet cells by trypsin treatment.Instruct the recombinant adenoviral vector transduction islet cells that c-Abl specific siRNA molecule transcribes with 5MOI.In contrast, use the adenovirus vector of the mixed and disorderly siRNA sequence of coding.Cell was reassembled 5 days external, be transplanted to afterwards under the scrotum of homology mice.Mice is treated and given as mentioned analyzing like that.
Consider inherent toxicity of adenovirus vector and immunogenicity, it may not be suitable for purpose in the body.Made up the AAV carrier of expressing same anti-c-Abl siRNA construct.When in external dispersion, about 30% pancreatic is by AAV transduction (result does not show).This is significantly less than the transduction efficiency that obtains with adenovirus vector, but enough high making can be estimated the c-Abl in the beta cell destruction in the body.
Method and apparatus
People's islets of langerhans.(glucose in RPMI1640 of 5.6mM+10%FCS) cultivate down by free-floating in the standard culture condition for people's islets of langerhans.
Flow cytometry and cell sorting.Use has the cell sorting ability and makes the green fluorescent protein that spends stable form as the sub flow cytometer (FACSCalibur of report, Becton-Dickinson) assess effectiveness easily, and the transfectional cell of sorting simultaneously is used for further experiment or transplants.Therefore, no longer must depend on the genetically modified insulinoma cell clone's of selected stably express generation (problem of clonal vaviation).Can use isolating transient transfection cell from non-transfected cells.In addition, flow cytometer also can be assessed cell viability (dyeing of iodate third ingot) and apoptosis (anti--activation caspase-3 antibody).In addition, flow cytometer also is used for the sorting of rodent beta cell, cell cycle analysis, mitochondrial membrane potential, oxygen-derived free radicals generation and immunofluorescence research (insulin, glucagon, Bcl-2).

Embodiment 3: to the inductive protective effect mechanism at beta cell death and diabetes of Compound I in the body Research
Background:The molecular weight of a known compound I inhibition c-Abl-wide expression is about the protein tyrosine kinase of 145kDa.Under physiological condition, proved that c-Abl participates in regulating cytoskeleton function such as migration and cellularity and cell cycle progression.Yet, when cellular exposure in multi-form stress the time, the c-Abl highly activation that becomes, this causes cell cycle to be prevented and apoptosis.
The nearest result who obtains:C-Abl has expression in bTC-6 cell and isolated rat islets of langerhans, use the pharmacologically active agents Compound I suppress c-Abl active produce at by streptozotocin, proinflammatory cytokine or by nitric oxide donors the protective effect of inductive beta cell death.Compound I such as salt I are the selective depressants that is used for the treatment of CML clinically.Except c-Abl, known compound I suppresses ABL oncogene, c-KIT, PDGF beta receptor and c-Abl homologue ARG.Thereby the effect that is necessary to prove salt I is via the inhibition specificity mediation of c-Abl.Therefore has specific siRNA processing bTC-6 cell with mixed and disorderly siRNA or to c-Abl.Utilize Lipofectamine reagent that siRNA is introduced cell.Follow the trail of cell 1 or 3 days then, separate total RNA afterwards.By the synthetic cDNA of RNA and to utilize c-Abl (35 circulations) and b-actin be that beta-actin (20 circulations) has specific primer it is carried out pcr amplification.On agarose gel, separate the PCR product and observe by ethidium bromide staining.Handle at siRNA and to fail to observe c-Abl band (not shown) in the back 24 hours cell.Yet at 72 hours, c-Abl took out of existing.These results suggest knock out the courier at the siRNA of c-Abl via the mediation of RNAi mechanism, and this effect only is instantaneous (data not shown) in the bTC-6 cell of breeding rapidly.After determining that c-Abl mRNA level can be reduced by the RNAi technology, whether the bTC-6 cell that next we studied disappearance c-Abl mRNA increases the combination that responds IL-1 β, IFN-γ and TFN-α with cell death.Opposite with viewed situation in former generation islet cells, the bTC-6 cell is the death by apoptosis response cytokine preferentially.And the bTC-6 cell death of cytokine induction couple of days after processing is resisted (Fig. 3) forcefully by the specific siRNA of c-Abl.This shows that the proteic effect that causes siRNA to handle of may having enough to meet the need slowly of c-Abl postpones.But what is more important, Notes of Key Data SALT I inductive protective effect at NO donor and combination of cytokines suppress mediation by c-Abl.
Relation between c-Abl and the different map kinase: studied c-Abl and different map kinase p38, the JNK that may work as c-Abl downstream effect thing and relation between the ERK.For this purpose, rat Langerhans islet with 10 μ M Compound I preincubates 24 hours, is exposed to the combination 20 minutes of DETA/NO (2mM) and IL-1 β, IFN-γ and TNF-α then.With phosphoric acid specific antibody and immunoblotting islets of langerhans is carried out p38, JNK2 and ERK1/2 analysis of Phosphorylation then.The inductive p38 of DETA/NO, JNK and ERK activation are resisted in Compound I such as salt I treatment partly (25-45%), and strengthen the MAPK activation (table 5 and 6) of cytokine induction.

These inductive nitric oxide generations of sustenticular cell factor as a result are at least in part via c-Abl path activation JNK and p38, and this causes beta cell death.On the other hand, as if active early stage rising of p38 that occurs in the response of the pair cell factor and JNK suppressed by c-Abl.Yet, in this case, might cytokine inductive p38 and active this first peak value representative of JNK cause the physiological responses that gene expression changes and propagation increases, and be not apoptosis itself.For example, shown that the cytokine activation of p38 and JNK participates in the follow-up expression of iNOS gene.Under this background, the p38 of present viewed c-Abl mediation and JNK suppress to have explained well that viewed nitric oxide generation increases in the islets of langerhans of handling with cytokine and Compound I.
Because these data, the c-Abl performance stress with the sensor effect of outside dead signal, the c-Abl activation can cause JNK and kinase whose phosphorylation of p38MAP and activation and finally cause beta cell death.
Additional experiment:
1. the expression of research c-Abl in beta cell.The expression of c-Abl mRNA can be assessed by PCR in real time.The c-Abl mRNA level of islets of langerhans and the c-Abl mRNA level of other tissue are compared.C-Abl is had specific fluorescent probe available from TIB MOLBIOLSyntheselabor (Berlin, Germany), with reference to c-Abl cDNA standard curve fluorescence signal is carried out quantitatively with the Lightcycler instrument.C-Abl mRNA molecular number is standardized as b-actin mRNA molecule.The c-Abl mRNA content of people's islets of langerhans and the c-Abl mRNA content of liver, muscle, kidney, spleen, brain and lung are compared.Abreast, to carrying out quantitatively with the expression of the c-Abl similarity SRCA RG that plays a role with the similar mode of c-Abl.Under this background, determined whether c-Abl mRNA level stress be influenced by cytokine, oxidative stress and ER.People's islets of langerhans is exposed to IL-1 β (25U/ml)+IFN-γ (1000U/ml)+TNF-α (1000U/ml), 100mM hydrogen peroxide or brefeldin A (10 μ M) 3 hours, analyzes the expression of c-Abl mRNA then by PCR in real time.
Research to beta cell stress response in c-Abl whether by phosphorylation.By with pCDNA3/c-Abl plasmid (available from Ludwig Institute, University of Uppsala) fat transfectional cell, carry out Geneticin (geneticin) resistance then and select to produce the stable bTC-6 cell line of expressing wild type c-Abl.To cross the bTC-6 cellular exposure of expressing c-Abl then in IL-1, brefeldin A and DETA/NO 20,60,360 minutes, with determine the pair cell factor, ER stress with c-Abl in the nitric oxide production response whether by phosphorylation.Then in the presence of inhibitors of phosphatases with cell homogenates, and utilize K-12 anti--c-Abl antibody (Santa Cruz) immunoprecipitation c-Abl.At PAGE with after transferring to nylon leaching film, with carrying out tyrosine phosphorylation and total tyrosine phosphatase fractional analysis at aminoacid 245 places to the c-Abl band by two phosphoric acid specificity c-Abl antibody (Tyr245 and Thr735) and the phosphotyrosine antibody 4G10 that Cell Signaling Technology obtains.C-Abl is active during by excessive phosphorylation increases as amino acid residue Tyr245 and Thr735.
3. whether the Subcellular Localization of research c-Abl stress influence by beta cell.On cover plate, cultivate the bTC-6 cell of expressing c-Abl, be exposed to cytokine, brefeldin A and nitric oxide donors 6 hours then.After fixing, sealing and saturatingization, pass through confocal microscopy microscopy analysis of cells with Mitotracker green (MolecularProbes) (it dyes green with mitochondrion) and K-12c-Abl antibody (Santa Cruz) (itself and yoke close two of rhodamine resist c-Abl is dyed redness).If c-Abl is repositioned to mitochondrion by ER, the pattern that then dyes becomes unique yellow by dispersive redness and green.
4. identify the downstream targets of c-Abl.For this purpose, produced the CbTC-6 cell that instantaneous mistake is expressed the c-Abl of wild type or constitutive activity form.With pcDNA3/c-Abl-carrier and GFP-expression vector fat transfection (Lipofectamine+Lipofectamine plus) bTC-6 cell.This produces the 20%GFP-positive cell, and it awaits being enriched to more than 75% by FACS.With the cell coated plate of sorting and cultivated 24 hours, carry out the analysis of Phosphorylation of candidate's target ERK, JNK, p38, I κ B, p53 and AKT (the downstream effect thing of PI3K) then.Analyze preceding 20 and 120 minutes, have or the condition of salt-free I such as Compound I under, with amycin (the nuclear activation of c-Abl) or DETA/NO (the endochylema activation of c-Abl) irritation cell.Utilize the phosphorylation (ser/thr) of the phosphoric acid specific antibody (CellSignal Technology) of commercially available acquisition by the target protein of immunoblotting assay deduction.Whether this can be disclosed in candidate's effector in the activatory response of c-Abl by phosphorylation and activation.Utilize traditional Western engram technology to analyze Bcl-2, Bcl-XL and Aph2 level.In some cases, the immunoprecipitation of candidate albumen is necessary sometimes, to improve the sensitivity of immunoblotting assay.For the phosphorylation of tyrosine-specific, with candidate's effector immunoprecipitation and utilize the anti-phosphotyrosine antibody of PY20 to analyze by immunoblotting.
5. the interaction between research c-Abl and the Shb:
Carry out the interaction that this experiment is intended to understand the deduction between c-Abl and the adaptin Shb.Shb is the albumen that contains the SH2 domain, it has the motif of proline rich at the N-end, have central PTB (phosphotyrosine combination)-domain, several potential tyrosine phosphorylation sites and the terminal SH2 domain of C-, known its produces in the signal conduction complex at response tyrosine-kinase enzyme activation and plays a role.It is worth noting that the apoptosis tendency of crossing the beta cell of expressing Shb increases.Really, when not having serum or existing when cultivating islets of langerhans under the condition of cytotoxic cytokines, express the transgenic mice that is in the SHB under the control of rat insulin promoter and show the apoptosis speed of rising.Because nearest report proof Shb family member Shd is in conjunction with c-Abl and interact with it, might be in beta cell c-Abl via playing a role with the interaction of Shb.In order to study this point, will be by transient transfection to cross expression c-Abl, the cell of Shb or Shb mutant is handled with pervanadate, then with anti--Shb-antibody mediated immunity precipitation.Then immunoprecipitate is carried out the tyrosine phosphorylation of immunoblotting with the Shb of analysis c-Abl and Shb level and c-Abl co-precipitation.Preliminary discovery shows c-Abl and Shb co-precipitation, and vice versa, and c-Abl crosses to express and causes the Shb-phosphorylation to increase (data not shown).These find to support that Shb is the viewpoint of c-Abl kinase substrate.
In order further to understand the interaction between c-Abl and the Shb, carried out fusion rotein pull-down experiment.GST, GST-ShbSH2 and GST-ShbPTB/ proline rich domain fusion rotein and the COS cell homogenates that contains high-level c-Abl are interacted.Described reaction is to carry out under the condition that has or do not have pervanadate to stimulate, and has been the importance of understanding c-Abl tyrosine phosphorylation and phosphotyrosine interpolation, has been understanding SH2-domain and the interactional importance of phosphotyrosine residue.By immunoblotting the pull-down product is carried out c-Abl and phosphoric acid-c-Abl analysis.These experiments show which domain of Shb is absolutely necessary for combining with non-phosphorylating or phosphorylation c-Abl.Using c-Abl fusion rotein (c-Abl-SH2 and c-Abl-SH3) to test to estimate which domain accordingly is vital for combining with Shb.
In order to determine whether the Shb-c-Abl interaction mediated the islet cells of expressing Shb apoptotic enhancing tendency takes place in the response that different toxicity are stimulated, from the Shb transgenic mice, separate islets of langerhans, and be exposed to cytokine, DETA/NO and streptozotocin, with or carry out pretreatment without Compound I.The pair cell apoptosis quantitatively also will be compared with the data of the control mice of parallel acquisition by the data that transgenic mice obtains with downright bad carrying out.If combined thing I of Shb islets of langerhans enhanced cell apoptosis and downright bad level such as salt I normalization might the Shb-c-Abl interaction may be necessary apoptosis regulation paths then.
