Vascular endothelial growth factor-a (VEGF-A) is a protein secreted by podocytes that is necessary for survival of endothelial cells, podocytes and mesangial cells. VEGF-A regulates slit-diaphragm signaling and podocyte shape via VEGFR2-nephrin-nck-actin interactions. Chronic hyperglycemia-induced excess podocyte VEGF-A and low endothelial nitric oxide drive the development and the progression diabetic nephropathy. The abnormal cross talk between VEGF-A and NO pathways is fueled by the diabetic milieu increased oxidative stress. Recent findings on these pathogenic molecular mechanisms provide new potential targets for therapy for diabetic renal disease.
