2. Objectives of COST Action B5

Non-insulin dependent diabetes mellitus (NIDDM) or Type II diabetes is a considerable health burden of western societies. No reliable screening method is available to detect the persons who are predisposed in the population and due to our incomplete knowledge on the molecular mechanisms leading to NIDDM we have very few means to influence the onset and development of this diverse disease. To change this situation COST B5's main objectives are:

5. Summary of the project proposals accepted by the Action

5.1. PHARE TD&QM Programme H 9305-02/1030, Participation in EU programme COST B5 on NIDDM by examining the therapeutic potential of stress proteins and their regulation in diabetes (National Committee of R& D, Hungary; 50,000 euros)

The project summarized a plan of a Hungarian and international cooperation to link two, heretofore barely connected areas of science: stress proteins and diabetes research. The main milestones of the work were the following: (1) Analysis of the biochemical and functional changes of glucose-regulated and heat shock proteins in diabetes mellitus. The synthesis of molecular chaperones is markedly impaired in diabetes. However, this seldom leads to a significant decrease in their cellular protein level. In agreement with the unchanged levels of chaperones the efficiency of the chaperone activity increases in livers of STZ-diabetic rats compared to control animals. The exact mechanism of this adaptive response is currently investigated. (2) Examination of the therapeutic potential of known stress protein-inducers (such as amino-acid analogues) in easing the consequences of diabetes. The experiments identified canavanine as a potent stress protein-inducer of retinal tissue at doses which are far (5-10 times less) from the reported toxic levels. Canavanine-pretreatment significantly improved the electrical responses of the diabetic retina. The improvement was reaching (or in some cases even surpassing) the control level. Unfortunately the direct therapeutic potential of canavanine itself is probably limited by the markedly increased aggressivity of the canavanine-treated animals. The reasons of this CNS-hyperfunctioning are not clear, but resemble to similar effects of other stress-protein inducers and clearly require further studies. (3) Study the effect of established antidiabetic drugs and drug-candidates (such as inositol-glycans) on the repair and quality control processes governed by stress proteins. The experiments identified that protein level of Grp94 measured by the 9G10 monoclonal antibody, mRNA-levels of various chaperones, and chaperone activity of cell extracts may be good tools for monitoring the effects of various antidiabetic drugs. For this measurement system only experiments with prolonged incubation (days) seem to be suitable where larger amounts (several mg-s) of the drug or drug-candidate are available.

5.2. Molecular mechanisms of the etiology of non-insulin dependent diabetes mellitus (Federal Office for Education and Science, Switzerland; 195,000 euros)

The project summarized a plan of a Swiss-international cooperation to examine several aspects of hormone action in various disease states. The main milestones of the work were the following: (1) Interactions of growth hormone (GH) and leptin. Exogenous GH by itself in normal humans and rats had no effect on leptin levels although leptin concentrations in hypophysectomized and therefore GH-deficient rats were markedly reduced. In contrast, GH-deficient humans responded on hormone treatment with elevated leptin levels, and increased C-peptide. (2) Interactions of insulin-like growth factor I (IGF-I) and leptin. IGF-I reduced leptin mRNA concentration as well as serum levels in rats and humans. A strong correlation between the inhibiting effect of IGF-I on insulin secretion and the reduction of leptin levels was observed. Since the effect on insulin preceded the decrease in leptin levels an IGF-I/insulin/leptin interaction-scheme has been proposed.

10. Plans for the future

Based on the success of the present Action and on the changes in research focus of NIDDM research the participants of the Action decided to extend and continue of the Action by proposing a new COST Action on "Insulin resistance, obesity and diabetes mellitus in the elderly". The new Action will keep some of the most important aspects of COST Action B5 but will also significantly re-shape and extend it by focusing on obesity- and aging-related aspects. The new Action has been accepted by the Council of COST Senior Officials in May 1999, and is open for interested research groups to join.

Objectives of the proposed new COST Action

General objectives

Various steps of insulin action will be studied starting from the insulin receptor and following insulin action till it reaches the cell nucleus with special emphasis on the investigation of pathological changes of the molecular mechanism of insulin action in insulin resistance, obesity and NIDDM of the aged people. This research acitivity is thought to lead to the development new drug-candidates for the curing-easing of the consequences of this diverse disease. Ongoing research of candidate genes as well as various differential screening methods will also be coordinated with the new Action.

Specific objectives

The following steps of insulin action will be studied to gain a better understanding of the etiology of insulin resistance, obesity and NIDDM of the aged people, in hope to develop drug-candidates and a reliable screening method to detect the individuals with inherited risk for the disease. The list of secondary objectives is open for amendments incorporating the specific aims of new goups willing to participate in the concerted action. To join to the proposed research action an expertise in insulin (leptin, insulin-like growth factor) dependent signal transduction, insulin resistance/obesity-related physiological changes and/or in structural studies of insulin resistance/obesity-related genes is required.
