Vascular endothelial growth factor governs endothelial nitric-oxide synthase expression via a KDR/Flk-1 receptor and a protein kinase C signaling pathway
The mechanism by which vascular endothelial growth factor (VEGF) regulates endothelial nitric-oxide synthase (eNOS) expression is presently unclear. Here we report that VEGF treatment of bovine adrenal cortex endothelial cells resulted in a 5-fold increase in both eNOS protein and activity. Endothelial NOS expression was maximal following 2 days of constant VEGF exposure (500 pM) and declined to base-line levels by day 5. The elevated eNOS protein level was sustained over the time course if VEGF was co-incubated with L-N(G)-nitroarginine methyl ester, a competitive eNOS inhibitor. Addition of S-nitroso-N-acetylpenicillamine, a nitric oxide donor, prevented VEGF-induced eNOS up-regulation. These data suggest that nitric oxide participates in a negative feedback mechanism regulating eNOS expression. Various approaches were used to investigate the role of the two high affinity VEGF receptors in eNOS up-regulation. A KDR receptor-selective mutant increased eNOS expression, whereas an Flt-1
