Effects of nitric oxide donors on vascular endothelial growth factor gene induction.

Abstract

Nitric oxide (NO) has been reported to modulate the vascular endothelial growth factor (VEGF) gene by accumulating hypoxia-inducible factor-1alpha (HIF-1alpha) protein, but there is a contradiction among effects of various NO donors. The effects of NO donors including S-nitroso-N-acetyl-penicillamine (SNAP), S-nitroso-glutathione (GSNO), 1-hydroxy-2-oxo-3,3-bis(2-aminoethyl)-1-triazene (NOC18), 3-[(+/-)-(E)-ethyl-2(')-[(E)-hydroxyimino]-5-nitro-3-hexenecarbamoyl]-pyridine (NOR4), 3-morpholinosydnonimine (SIN-1), and nitroprusside (SNP) on the VEGF reporter gene were examined. SNAP, GSNO, NOC18, and NOR4 enhanced the VEGF reporter activity under normoxia and modulated the hypoxic induction. In contrast, SNP had only an inhibitory effect. An NO scavenger attenuated the reporter activation by NO donors except NOR4, but did not ameliorate the inhibitory effect of SNP. A reducing compound dithiothreitol suppressed NO-induced activation of the VEGF reporter gene. SNAP, GSNO, and NOC18 induced the accumulation of HIF-1alpha protein, while others did not. These results suggest that SNAP, GSNO, and NOC compounds are suitable for pharmacological studies in HIF-1-mediated VEGF gene activation by NO.
