Definitions

  • the present invention relates to a method for modulating, inhibiting or decreasing or preventing beta cell degeneration, loss of beta cell function, beta cell dysfunction, and/or death of beta cells, such as necrosis or apoptosis of beta cells in a subject comprising adminis- tering a GLP-1 agonist to said subject.
  • coagulative necrosis This is an abnormal morphological appearance, detected in tissue examined under the microscope.
  • the changes, which affect aggregates of adjacent cells or functionally related cohorts of cells, are seen in a variety of contexts produced by accident, injury, or disease.
  • oxygen deprivation oxygen deprivation
  • hyper- thermia hyper- thermia
  • immunological attack and exposure to various toxins that inhibit crucial intracellular metabolic processes.
  • Coagulative necrosis is the classical form of cell change seen when tis- sues autolyze (digest themselves) in vitro.
  • Apoptosis is an active process of cellular self-destruction that is regulated by extrinsic and intrinsic signals occurring during normal development. It is well documented that apoptosis plays a key role in regulation of pancreatic endocrine beta cells. There is increasing evidence that in adult mammalians the beta-cell mass is submitted to dynamic changes to adapt insulin production for maintaining euglycemia in particular conditions, such as pregnancy and obesity (J. Dev. Physiol. 5: 373, 1983 and Endocrinology 130: 1459, 1992). The control of beta cell mass depends on a subtle balance between cell proliferation, growth and cell death (apoptosis). A disruption of this balance may lead to impairment of glucose homeostasis.
  • glucose intolerance develops with aging when beta cell replica- tion rates are reduced (Diabetes 32: 14, 1983) and human autopsy studies repeatedly showed a 40-60% reduction of beta cell mass in patients with non- insulin-dependent-diabetes mellitus compared with nondiabetic subjects (Am. J. Med. 70: 105, 1981 and Diabetes Res. 9: 151, 1988). It is generally agreed that insulin resistance is an invariable accompaniment of obesity but that normoglycemia is maintained by compensatory hyperinsulinemia until the beta cells become unable to meet the increased demand for insulin, at which point Type 2 Diabetes begins. Apoptosis is also associated with diseases states such as cancer, immunological disorders, like multiple sclerosis, and AIDS, and neurodegenerative disorders (Science 267: 1449, 1995), like Alzheimers disease, stroke, and Parkinson's disease.

Description

SE OF GLP-1 AGONISTS FOR THE INHIBITION OF BETA CELL DEGENERATION
The present invention relates to a method for modulating, inhibiting or decreasing or preventing beta cell degeneration, loss of beta cell function, beta cell dysfunction, and/or death of beta cells, such as necrosis or apoptosis of beta cells in a subject comprising adminis- tering a GLP-1 agonist to said subject.
Background
What most textbooks of pathology describe as cell death is coagulative necrosis. This is an abnormal morphological appearance, detected in tissue examined under the microscope. The changes, which affect aggregates of adjacent cells or functionally related cohorts of cells, are seen in a variety of contexts produced by accident, injury, or disease. Among the environmental perturbations that may cause cell necrosis are oxygen deprivation (anoxia), hyper- thermia, immunological attack, and exposure to various toxins that inhibit crucial intracellular metabolic processes. Coagulative necrosis is the classical form of cell change seen when tis- sues autolyze (digest themselves) in vitro.
Apoptosis is an active process of cellular self-destruction that is regulated by extrinsic and intrinsic signals occurring during normal development. It is well documented that apoptosis plays a key role in regulation of pancreatic endocrine beta cells. There is increasing evidence that in adult mammalians the beta-cell mass is submitted to dynamic changes to adapt insulin production for maintaining euglycemia in particular conditions, such as pregnancy and obesity (J. Dev. Physiol. 5: 373, 1983 and Endocrinology 130: 1459, 1992). The control of beta cell mass depends on a subtle balance between cell proliferation, growth and cell death (apoptosis). A disruption of this balance may lead to impairment of glucose homeostasis. For example, it is noteworthy that glucose intolerance develops with aging when beta cell replica- tion rates are reduced (Diabetes 32: 14, 1983) and human autopsy studies repeatedly showed a 40-60% reduction of beta cell mass in patients with non- insulin-dependent-diabetes mellitus compared with nondiabetic subjects (Am. J. Med. 70: 105, 1981 and Diabetes Res. 9: 151, 1988). It is generally agreed that insulin resistance is an invariable accompaniment of obesity but that normoglycemia is maintained by compensatory hyperinsulinemia until the beta cells become unable to meet the increased demand for insulin, at which point Type 2 Diabetes begins. Apoptosis is also associated with diseases states such as cancer, immunological disorders, like multiple sclerosis, and AIDS, and neurodegenerative disorders (Science 267: 1449, 1995), like Alzheimers disease, stroke, and Parkinson's disease.

In a still further embodiment of the invention the GLP-1 agonist is a GLP-1 derivative. In a further embodiment of the invention the GLP-1 derivative has one or more lipophilic substituents attached to the parent peptide. The lipophilic substituents make the profile of action of the parent GLP-1 peptide more protracted, make the parent GLP-1 peptide more me- tabolically and physically stable, and/or increase the water solubility of the parent GLP-1 pep- tide.
The lipophilic substituent is characterised by having a solubility in water at 20°C in the range from about 0.1 mg/100 ml water to about 250 mg/100 ml water, preferable in the range from about 0.3 mg/100 ml water to about 75 mg/100 ml water. For instance, octanoic acid (C8) has a solubility in water at 20°C of 68 mg/100 ml, decanoic acid (CIO) has a solubility in water at 20°C of 15 mg/100 ml, and octadecanoic acid (C 18) has a solubility in water at 20°C of 0.3 mg/100 ml.

In an embodiment, a lipophilic 'substituent is attached to the carboxy group of the R group of any Asp and Glu residue.
In another embodiment, a lipophilic substituent is attached to the carboxy group attached to the alpha-carbon of the C-terminal amino acid.
In a most preferred embodiment, a lipophilic substituent is attached to the epsilon- amino group of any Lys residue. Each lipophilic substituent contains a functional group which may be attached to a functional group of an amino acid of the parent GLP-1 peptide. For example, a lipophilic substituent may contain a carboxy 1 group which can be attached to an amino group of the parent GLP-1 peptide by means of an amide bond. In an embodiment, the lipophilic substituent comprises a partially or completely hydrogenated cyclopentanophenathrene skeleton.
In another embodiment, the lipophilic substituent is a straight-chain or branched alkyl group.

In a more preferred embodiment, the lipophilic substituent is tetradecanoyl. In a most preferred embodiment, the lipophilic substituent is hexadecanoyl.
In another embodiment of the present invention, the lipophilic substituent has a group which is negatively charged such as a carboxylic acid group. For example, the lipophilic substituent may be an acyl group of a straight-chain or branched alkane α,ω-dicarboxylic acid of the formula HOOC(CH2)mCO-, wherein m is an integer from 4 to 38, preferably an integer from 12 to 38, and most preferably is HOOC(CH2)*4CO-, HOOC(CH2)ι6CO-, HOOC(CH2)*8CO-, HOOC(CH2)20CO- or HOOC(CH2)22CO-.
In a preferred embodiment of the invention, the lipophilic substituent is attached to the parent GLP-1 peptide by means of a spacer. A spacer must contain at least two functional groups, one to attach to a functional group of the lipophilic substituent and the other to a functional group of the parent GLP-1 peptide.
In an embodiment, the spacer is an amino acid residue except Cys or Met, or a dipeptide such as Gly-Lys. For purposes of the present invention, the phrase "a dipeptide such as Gly- Lys" means any combination of two amino acids except Cys or Met, preferably a dipeptide wherein the C-terminal amino acid residue is Lys, His or Trp, preferably Lys, and the N-terminal amino acid residue is Ala, Arg, Asp, Asn, Gly, Glu, Gin, He, Leu, Val, Phe, Pro, Ser, Tyr, Thr, Lys, His and Trp. Preferably, an amino group of the parent peptide forms an amide bond with a carboxylic group of the amino acid residue or dipeptide spacer, and an amino group of the amino acid residue or dipeptide spacer forms an amide bond with a carboxyl group of the lipophilic substituent.
Preferred spacers are lysyl, glutamyl, asparagyl, glycyl, beta-alanyl and gamma- aminobutanoyl, each of which constitutes an individual embodiment. Most preferred spacers are glutamyl and beta-alanyl. When the spacer is Lys, Glu or Asp, the carboxyl group thereof may form an amide bond with an amino group of the amino acid residue, and the amino group thereof may form an amide bond with a carboxyl group of the lipophilic substituent. When Lys is used as the spacer, a further spacer may in some instances be inserted between the ε-amino group of Lys and the lipophilic substituent. In one embodiment, such a further spacer is succinic acid which forms an amide bond with the ε-amino group of Lys and with an amino group present in the lipophilic substituent. In another embodiment such a further spacer is Glu or Asp which forms an amide bond with the ε-amino group of Lys and another amide bond with a carboxyl group present in the lipophilic substituent, that is, the lipophilic substituent is a Nε-acylated lysine residue. In another embodiment, the spacer is an unbranched alkane ,ω-dicarboxylic acid group having from 1 to 7 methylene groups, which spacer forms a bridge between an amino group of the parent peptide and an amino group of the lipophilic substituent. Preferably, the spacer is succinic acid.

GLP-1 analogues and derivatives which can be used according to the present invention includes those referred to in WO 99/43705 (Νovo Nordisk A/S), WO 99/43706 (Novo Nordisk A/S), WO 99/43707 (Novo Nordisk A/S), WO 98/08871 (Novo Nordisk A/S), WO 99/43708 (Novo Nordisk A/S), WO 99/43341 (Novo Nordisk A/S), WO 87/06941 (The General Hospital Corporation), WO 90/11296 (The General Hospital Corporation), WO 91/11457 (Buckley et al.), WO 98/43658 (Eli Lilly & Co.), EP 0708179-A2 (Eli Lilly & Co.), EP 0699686-A2 (Eli Lilly & Co.) which are included herein by reference.
However, protracted acting GLP-1 derivatives, in particular those described in WO 98/08871 are more preferred. The most preferred GLP-1 derivatives are those in which the parent peptide has the formula GLP-1 (7-C), wherein C is 36, 37, 38, 39, 40, 41 , 42, 43, 44 and 45, wherein optionally a total of up to fifteen, preferably up to ten amino acid residues have been exchanged with any α-amino acid residue which can be coded for by the genetic code, said parent peptide comprising one or two lipophilic substituents having 4 to 40 carbon atoms, preferably from 8 to 25 carbon atoms, optionally via a spacer (such as γ-Glu or β-Ala). The substituents are preferably selected from acyl groups of straight-chained or branched fatty acids.
GLP-1 analogues and derivatives that include an N-terminal imidazole group and optionally an unbranched C6-Cιo acyl group attached to the lysine residue in position 34 are also embodiments of the invention. In a still further embodiment of the invention the GLP-1 agonist is selected from ex- endin as well as analogs, derivatives, and fragments thereof, e.g. exendin-3 and -4.
Examples of exendin as well as analogs, derivatives, and fragments thereof to be included within the present invention are those disclosed in WO 9746584 and US 5424286. US 5424286 describes a method for stimulating insulin release with exendin polypeptide(s). The ex- endin polypeptides disclosed include HGEGTFTSDLSKQMEEEAVRLFIE LKNGGX; wherein X = P or Y, and HX1X2GTFITSDLSKQMEEEAVRLFIEWLKNGGPSSGAPPPS; wherein X1X2 = SD (exendin-3) or GE (exendin-4)). The exendin-3 and -4 and fragments are useful in treatment of diabetes mellitus (types I or II) and prevention of hyperglycaemia. They normalise hyperglycaemia through glucose-dependent, insulin-independent and insulin- dependent mechanisms. Exendin-4 is specific for exendin receptors, i.e. it does not interact with vasoactive intestinal peptide receptors. WO 9746584 describes truncated versions of exendin peptide(s) for treating diabetes. The disclosed peptides increase secretion and biosynthesis of insulin, but reduce those of glucagon. The truncated peptides can be made more economically than full length versions.
In a still further embodiment of the invention the GLP-1 agonist is a non-peptide. In a further embodiment the GLP-1 agonist is a molecule, preferably a non-peptide, which binds to a GLP-1 receptor with an affinity constant, KTJ, below 1 μM, preferably below
100 nM.
Any possible combination of two or more of the embodiments described herein, is comprised within the scope of the present invention.
The term "GLP-1" means GLP-l(7-37) or GLP-1 (7-36) amide. The term "treatment" is defined as the management and care of a patient for the purpose of combating the disease, condition, or disorder and includes the administration of a GLP-1 agonist to prevent the onset of the symptoms or complications, or alleviating the symptoms or complications, or eliminating the disease, condition, or disorder. Treatment includes modulate, inhibit, decrease, reduce or arrest beta cell degeneration, such as necrosis or apoptosis of beta cells, in particular the programmed β-cell death known as apoptosis of β- cells as well as prevention of beta cell degeneration, such as necrosis or apoptosis of beta cells, in particular prevention of apoptosis of β-cells
The term "beta cell degeneration" is intended to mean loss of beta cell function, beta cell dysfunction, and death of beta cells, such as necrosis or apoptosis of beta cells. In the present context "a GLP-1 agonist" is intended to indicate a molecule, preferably
GLP-1 or an analogue or a derivative thereof, or exendin or an analogue or a derivative thereof, or a non-peptide, which binds to a GLP-1 receptor with an affinity constant, K-Q, below 1 μM, preferably below 100 nM. Methods for identifying GLP-1 agonists are described in WO 93/19175 (Novo Nordisk A/S). In the present context "a GLP-1 agonist" is also intended to comprise active metabolites and prodrugs thereof, such as active metabolites and prodrugs of GLP- 1 or an analogue or a derivative thereof, or exendin or an analogue or a derivative thereof, or a non-peptide. A "metabolite" is an active derivative of a GLP-1 agonist produced when the GLP-1 agonist is metabolized. A "prodrug" is a compound which is either metabolized to a GLP-1 agonist or is metabolized to the same metabolite(s) as a GLP- 1 agonist.
In the present text, the designation "an analogue" is used to designate a peptide wherein one or more amino acid residues of the parent peptide have been substituted by another amino acid residue and/or wherein one or more amino acid residues of the parent peptide have been deleted and/or wherein one or more amino acid residues have been added to trie parent peptide. Such addition can take place either in the peptide, at the N-terminal end or at the C-terminal end of the parent peptide, or any combination thereof. The term "derivative" is used in the present text to designate a peptide in which one or more of the amino acid residues of the parent peptide have been chemically modified, e.g. by alkylation, acylation, ester formation or amide formation.
The term "a GLP-1 derivative" is used in the present text to designate a derivative of GLP-1 or an analogue thereof. In the present text, the parent peptide from which such a deriva- tive is formally derived is in some places referred to as the "GLP-1 moiety" of the derivative. For a description of suitable dosage forms, dosage ranges, pharmaceutical formulations etc. reference is made to WO 98/08871 (Novo Nordisk A/S).
The route of administration may be any route, which effectively transports the active compound to the appropriate or desired site of action, such as oral, nasal, pulmonary, trans- dermal or parenteral.
Pharmaceutical compositions (or medicaments) containing a GLP-1 agonist may be administered parenterally to patients in need of such a treatment. Parenteral administration may be performed by subcutaneous, intramuscular or intravenous injection by means of a syringe, optionally a pen-like syringe. Alternatively, parenteral administration can be performed by means of an infusion pump. A further option is a composition which may be a powder or a liquid for the administration of the GLP-1 agonist in the form of a nasal or pulmonal spray. As a still further option, the GLP-1 agonist can also be administered transdermally, e.g. from a patch, optionally a iontophoretic patch, or transmucosally, e.g. bucally. As a still further option, the GLP-1 agonist (in particular GLP-1 or an analogue thereof) can also be administered by gene therapy, such as by implanting a cell line transformed with a vector such that it secretes the GLP- 1 agonist. The implanted cells may be encapsulated in semi permeable membranes, e.g. macro- or microen- capsulated. The above mentioned possible ways to administer a GLP-1 agonist are not considered as limiting the scope of the invention.
Pharmaceutical compositions containing a GLP-1 agonist may be prepared by conventional techniques, e.g. as described in Remington's Pharmaceutical Sciences, 1985 or in Remington: The Science and Practice of Pharmacy, 19th edition, 1995.
Thus, the injectable compositions of the GLP-1 agonist can be prepared using the conventional techniques of the pharmaceutical industry which involves dissolving and mixing the ingredients as appropriate to give the desired end product.
According to one procedure, the GLP-1 agonist is dissolved in an amount of water which is somewhat less than the final volume of the composition to be prepared. An isotonic agent, a preservative and a buffer is added as required and the pH value of the solution is adjusted - if necessary - using an acid, e.g. hydrochloric acid, or a base, e.g. aqueous sodium hydroxide as needed. Finally, the volume of the solution is adjusted with water to give the desired concentration of the ingredients. Examples of isotonic agents are sodium chloride, mannitol and glycerol.
Examples of preservatives are phenol, m-cresol, methyl p-hydroxybenzoate and benzyl alcohol.
Examples of suitable buffers are sodium acetate and sodium phosphate. Further to the above-mentioned components, solutions containing a GLP-1 agonist may also contain a surfactant in order to improve the solubility and/or the stability of the GLP-1 agonist.
A composition for nasal administration of certain peptides may, for example, be prepared as described in European Patent No. 272097 (to Novo Nordisk A/S) or in WO 93/18785. According to one embodiment of the present invention, the GLP-1 agonist is provided in the form of a composition suitable for administration by injection. Such a composition can either be an injectable solution ready for use or it can be an amount of a solid composition, e.g. a lyophilised product, which has to be dissolved in a solvent before it can be injected. The injectable solution preferably contains not less than about 2 mg/ml, preferably not less than about 5 mg/ml, more preferred not less than about 10 mg/ml of the GLP-1 agonist and, preferably, not more than about 100 mg/ml of the GLP-1 agonist. The GLP-1 agonist can be used in the treatment of various diseases. The particular GLP-1 agonist to be used and the optimal dose level for any patient will depend on the disease to be treated and on a variety of factors including the efficacy of the specific peptide derivative employed, the age, body weight, physical activity, and diet of the patient, on a possible combination with other drugs, and on the severity of the case. It is recommended that the dosage of the GLP-1 agonist be determined for each individual patient by those skilled in the art.
Experimental
Example 1
The male Zucker Diabetic Fatty fa/fa (ZDF) rat is a model of Type 2 diabetes. The rats are insulin resistant but normoglycemic from birth and they develop diabetes from about week 7 to week 10 of age. During the transitional period, the animals go through a state of impaired glucose tolerance. Although the animals are hyperinsulinemic before diabetes onset and during the early stages of diabetes, they later lose glucose-stimulated insulin secretion and finally become almost completely insulinopenic.
We have studied the effects of Arg34, Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))-GLP-l(7-37) therapy during a period of time when the animals would normally progress from having impaired glucose tolerance to having overt Type 2 diabetes. Three groups of male ZDF rats (Genetic Models Inc, Indianapolis, Indiana, USA) were studied and dosed subcutaneously bi- daily with either vehicle (group A), 30 (group B) or 150 μg/kg (group C) of Arg34, Lys26(N-ε- (γ-Glu(N-α-hexadecanoyl)))-GLP-l(7-37), n=6 per group. Animals were between 7 and 8 weeks old when dosing was initiated, and fed glucose levels were not different between the groups before dosing began. However, they were elevated compared to a group of non- diabetic Sprague-Dawley rats who had fed glucose levels significantly below the ZDF ani- mals (6.4±0.6 vs 5.8±0.8, mean±SD, p<0.02). This demonstrates the relative impaired glucose tolerant state of the ZDF animals when the study began.
Bromodeoxyuridine (BrDU) is incorporated in newly synthesized DNA and thus will label replicating cells. Six hours before sacrifice the rats were given an injection of 100 mg BrDU/kg intraperitoneally. After sacrifice the pancreata were fixed in 4% PFA, dehydrated, embedded in paraffin, and 3-4 mm sections double stained for BrDU and insulin for the measurement of beta-cell proliferation rate.
Insulin was stained with guinea pig anti-insulin, peroxidase-coupled rabbit anti-guinea pig Ig, and developed with AEC to give a red stain. BrDU was stained by monoclonal mouse anti- BrDU, biotinylated goat anti-mouse Ig, avidin peroxidase, and developed with DAB and CuS04 to give a dark brown stain. BrDU stained nuclei of cells with insulin stained cytoplasm was examined in more than 1500 cells per section. The examination of the sections were carried out with the origin of the sections blinded to the observer.
The rats treated with Arg34, Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))-GLP-l(7-37) showed a dose dependent increase in the fraction of beta-cells that had incorporated BrDU as a result of stimulated cell proliferation (fig. 1).
Neighbor sections were stained for insulin and the combination of glucagon-somatostatin- pancreatic polypeptide for the measurement of the relative mass of islet beta-cells and non- beta-cells. The beta-cells were stained for insulin as described above. The nonbeta-cells were stained with a mixture of monoclonal mouse anti-glucagon + rabbit anti-somatostatin + rabbit anti-pancreatic polypeptide, detected by biotinylated swine anti-multible Ig' s, avidin peroxi- dase, and developed with DAB and CuS0 to give a dark brown stain. The volume fractions of beta- and nonbeta-cells were estimated by point counting stereologic techniques.
The beta-cell fraction of the total pancreas was significantly higher in the rats given Arg34, Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))-GLP-l(7-37) at 30 ng/g for 6 weeks compared to vehicle treated rats, while there was no further increase in rats given doses of 150 ng/g (fig. 2). We have shown that volume of beta-cells after treatment with Arg34, Lys26(N-ε-(γ-Glu(N-α- hexadecanoyl)))-GLP- 1(7-37) increase at a dose (30 ng/g) where proliferation was not seen. This difference strongly indicates that an inhibition of apoptosis facilitated by the administered GLP-1 compound has taken place.
Furthermore, specific inhibition of beta-cell apoptosis by GLP-1 or GLP-1 analogs, that is GLP-1 agonists, can be shown in vitro by measuring inhibition of free fatty acid (FFA), glu- cose, sulfonylurea, or cytokine induced apoptosis in beta cells.
In vitro assays for characterizing the effect of GLP-1 or analogs thereof on the prevention of beta-cell apoptosis induced by FFA: Briefly, pancreatic islet, e.g. rat, mouse and human, isolated and cultured as described in, e.g. Diabetologia 19, 439, 1980; Transplantation, 68, 597, 1999; J. Mol. Med., 77, 93, 1999, Diabetes 48, 1230, 1999, J. Bio. Chem. 274, 18686, 1999; Proc. Natl. Acad. Sci. 95, 2498, 1999; . J. Bio. Chem, 273, 33501, 1998; Diabetologia 42, 55, 1999, with or without 0.1 -10 mM long-chain FF As (2:1 oleate/palmitate; Sigma) and with GLP-1 or GLP-1 analogs. Characterization of apoptotic beta cells can be analyzed as described below.
In vitro assays for characterizing the effect of GLP-1 or analogs thereof on the prevention of beta-cell apoptosis induced by glucose or sulfonylureas: Briefly, islets can be isolated and cultured as described in J. Bio. Chem, 273, 33501, 1998, and incubated in O-30 mM glucose as described in. J. Bio. Chem, 273, 33501, 1998, in order to induce apoptosis. In order to prevent the glucose induced apoptosis the islets can be co-incubated with GLP-1 or GLP-1 analogs. Alternatively apoptosis can be induced with 100-500 microM tolbutamide as described in J. Bio. Chem, 273, 33501, 1998. In order to prevent the tolbutamide induced apop- tosis the islets can be co-incubated with GLP-1 or GLP-1 analogs. Characterization of apoptotic beta cells can be analyzed as described below and as in . J. Bio. Chem, 273, 33501, 1998. In vitro assays for characterizing the effect of GLP-1 or analogs thereof on the prevention of beta-cell apoptosis induced by cytokines: Briefly, human and rat islets can be isolated and cultured as described in, e.g. Diabetologia 42, 55, 1999. Cytokine induced apoptosis of rat and human beta cells can be done as describe in Diabetologia 42, 55, 1999. In order to prevent the cytokine induced apoptosis -the islets can be co-incubated with GLP-1 or GLP-1 analogs. Characterization of apoptotic beta cells can be analyzed as described below and as described in Diabetologia 42, 55, 1999.
Apoptosis and inhibition thereof can be detected in the following way: The free 3' OH strand breaks resulting from DNA degradation which is associated with apoptosis can be detected with the terminal deoxynucleotidyl transferase-mediated dUTP-X3' nick end-labeling (TUNEL) technique (J Cell Biol 199: 493, 1992) or using the following kits e.g. In Situ Cell Death Detection kit; Boehringer Mannheim, Mannheim or ApoTag, Oncor, Gaithersburg, MD). Preparation of pancreatic sections or islet cultures for apoptosis staining using the TUNEL technique is described in (Diabetologia 42: 566, 1999 and Diabetes 48: 738, 1999).
Apoptosis can also be detected by electrophoresis of the soluble DNA fraction isolated from cultured islets by quantifying the ladder-like appearance as described in (PNAS 95: 2498, 1998).
Finally apoptosis can be detected by double staining of cultured beta cells/islets with the DNA binding dyes Hoechst 33342 and propidium iodide as described in (Diabetologia 42 : 55, 1999). Example 2
Neonatal rats were sacrificed and pancreata were aseptically isolated. Islets of Langerhans were isolated by standard techniques. Intact islets were cultured in 6-well tissue culture plates at 750 islets/well (Nunc, Roskilde, Denmark) with or without 40 U/ml recombinant rat inter- leukin 1, 100 U/ml interferon-γ, and 100 U/ml tumor necrosis factor-α (all from Peprotech, London, UK) and the indicated doses of the GLP-1 derivative, Arg34, Lys26(N-ε-(γ-Glu(N-α- hexadecanoyl)))-GLP- 1(7-37). After 24 hours of in vitro culture, single cell suspensions were obtained from the islets by gentle triturating in trypsin. After 2 rounds of washing, islet cells were reacted with annexin V-FITC and propedium iodide (PI) using a commercial staining kit according to the manufactures recommendations (Pharmingen, San Diego, CA, USA). At the end of incubation the samples were analyzed by flow cytometry using a FACScalibur (Becton Dickinson, Mountain View, CA, USA). Dead cells were excluded by gating on Pi-negative cells, 25000 viable cells were acquired per sample. Data were analyzed using the CellQuest software (Becton Dickinson).
Figure 3 shows that 24 hours incubation with the cytokine mix induced a substantial apoptosis in the neonatal rat islets cells. When islet cells were cultures in the presence of 100 nM of Arg34, Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))-GLP-l(7-37), an approximately 50 % reduc- tion in the cytokine-induced apoptosis was observed. The figure also shows that Arg34,
Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))-GLP- 1(7-37) itself had no effect on the level of islet cell apoptosis. These data demonstrate that Arg34, Lys26(N-ε-(γ-Glu(N-α-hexadecanoyl)))- GLP-l(7-37), is able to block cytokine-induced apoptosis in islet cells ex vivo.
