Funded Activity Summary

Diabetes is a disease that affects 100 million people worldwide and this number is expected to double in the next twenty years. This disease is characterised by high blood sugar levels which over prolonged periods of time can affect the function of the kidneys and eyes as well as causing heart attacks and strokes. A main contributing factor to diabetes is the inability of the pancreas to secrete insulin, the hormone that is responsible for keeping blood sugar levels in the normal range. The reason for this inability of the pancreas to secrete enough insulin is not known. It is known however, that both genetic and environmetal factors are responsible. The aim of this investigation is to determine the biochemical and genetic reason for decreased insulin secretion from an animal model of diabetes called DBA-2J mouse. Specifically we will be studying the effects of long-term increased sugar and fat on the function of the insulin producing cells of the pancreas, in order to identify the biochemical pathway responsible for reduced insulin secretion. In parallel we will be investigating the gene or genes in DBA-2J mice that are responsible for decreased insulin secretion and pancreatic cell death. This will provide clues as to the genes that may be responsible for diabetes in humans. This project will provide crucial information on the cause of reduced insulin secretion both at the cellular and genetic level, and will lead to a better understanding of the cause of diabetes.
