The effects of sodium orthovanadate, an inhibitor of protein tyrosine phosphatases, on the endothelial nitric oxide (NO) pathway were studied in vitro. Vanadate caused endothelium-dependent relaxations in isolated porcine coronary arteries, which were abolished by N omega-nitro-L-arginine methyl ester. The
