OBJECTIVE
Hypoxia or exposure to excessive reactive oxygen or nitrogen species could induce S-nitrosylation of various target proteins, including GTPases of the Ras-superfamily. Under hypoxic conditions, the Ras-protein is translocated to the cytosol and interacts with the Golgi complex, endoplasmic
Cultured human umbilical vein endothelial cells (EC) were exposed to hypoxia for various time periods followed by reoxygenation, and production of both O2- and H2O2 by EC was measured using the cytochrome c and scopoletin methods, respectively. Production of significant amounts of O2- was observed
