Long-term blockade of vascular endothelial growth factor receptor-2 aggravates the diabetic renal dysfunction associated with inactivation of the Akt/eNOS-NO axis

Abstract

Long-term selective blockade of VEGFR-2 by dRK6 had deleterious renal effects, and this was associated with downregulation of the Akt/eNOS-NO axis in db/db mice. Short-term VEGFR-2 blockade did not improve the renal phenotypes and the albuminuria. These findings suggest that VEGF-A-VEGFR-2 inhibition, regardless of how long it may be, does not ameliorate diabetic nephropathy in type 2 diabetes.
