Project description:

The function of the Rac1 regulator ELMO1 in the vasculature and in renal development under high glucose in zebrafish and in human diabetic nephropathy
Glucose-induced microangiopathy and nephropathy are diabetes-associated diseases. The Rac1 regulator ELMO1 is an important regulator of vascular development in zebrafish and polymorphisms in different regions of the human ELMO1 gene are associated with diabetes-associated nephropathy. The aim of this project is to analyze ELMO1’s function in the development of glucose-associated pathophysiological disorders in zebrafish and in diabetic patients. The project will include expression analyses in zebrafish and in diabetic patient samples; loss-of-function and gain-of-function experiments in zebrafish and biochemical studies in vitro.
