The role of FBPase in beta cell dysfunction

Funded Activity Summary

Type 2 diabetes is caused by multiple genetic defects, resulting in high blood sugar levels. These high sugar levels are primarily due to a decrease in the concentration of insulin, a hormone produced by the pancreas. A number of recent studies have aimed to identify which genes are regulated under conditions that mimic diabetes. One gene shown to have altered expression levels under these conditions is an enzyme called fructose-1,6-bisphosphatase (or FBPase). This enzyme is involved in the metabolism of sugar and is usually expressed at undetectable levels in the pancreas, but when blood sugar levels are high, the amount of FBPase in the pancreas increases considerably. We hypothesise that this increase in FBPase may contribute to the decrease in insulin secretion by the pancreas, seen in the diabetic state. The aim of this proposal therefore is to study mice that we have modified to express increased FBPase specifically in the pancreas, in order to determine whether this will lead to a decrease in insulin release and to diabetes. If this is the case, then FBPase could be targeted for the development of drugs that would improve the control of blood sugar levels in diabetes.
