Research Area

1. Gene therapy using a dog model of glycogen storage disease type Ia

Current Research

GSD Ia is an inherited metabolic disorder caused by glucose-6-phosphatase (G6Pase) deficiency, and we have characterized a canine model for GSD Ia. Currently, nutritional treatment has improved outcome; however, hypoglycemia and long-term complicationsstill occur. Comnplete biochemical correction of GSD Ia is possible by replacement of G6Pase in liver, as shown by liver transplantation. We have demonstrated G6Pase introduction in the GSD Ia liver following administration of an AAV vector, accompanied by decreased liver glycogen content and correction of hypoglycemia and hypercholesterolemia. We are now pursuing regulated expression of G6Pase driven by the endogenous G6Pase promoter. Regulated G6Pase expression with AAV vectors could promote normal glucose metabolism and prevent long-term complications of GSD Ia in the canine model.
