Brief description Type 2 diabetes is a common condition characterised by high blood glucose, that afflicts 700,000 Australians. It causes blindness, kidney failure and an increased risk of heart attack and stroke. despite intensive study over many years, the reasons for the elevated blood glucose in this condition are not fully understood. Several abnormalities can contribute to the high glucose and different researchers have proposed different defects as the initial cause. It has proven difficult to unravel the sequence of events in the evolution of the syndrome because high glucose can cause insulin resistance and a defect in insulin secretion, both of which can lead to high blood glucose. One approach to study the consequences of specific defects is to genetically engineer them. The aims of this project are to: 1. make a mouse with reduced ability to store glucose in muscle. 2. test the metabolic consequences of a defect in the manufacture of glycogen (starch) in muscle. 3. study the effects of combining a defect in glucose storage with one that results in an oversupply of glucose. 4. study the effects on a mouse with a genetic predisposition for failure of beta cells (insulin making cells) of a defect in muscle glucose storage and over production of glucose. A successful completion of this grant will greatly enhance our understanding of how blood glucose is increased in Type 2 diabetes.
