Abstract A 24-h incubation with hydrogen peroxide (0.65 mM) markedly reduced viability of cultured endothelial cells, Preincubation with aspirin (3-30 mu M) protected endothelial cells from hydrogen peroxide-induced toxicity and increased viability in a concentration-dependent fashion by up to 64% of control, A similar protection was observed with D-alpha-tocopherol acetate (vitamin E, 3-30 mu-M) The cytoprotective effects of aspirin and vitamin E against hydrogen peroxide were overadditive suggesting different mechanisms of antioxidant action, In agreement with this, cytotoxicity induced by iron, the main catalyst of oxygen radical formation, was substantially reduced by aspirin but not vitamin E. These results show that aspirin protects endothelial cells from oxidative stress possibly via binding or chelation of free cytosolic iron, Moreover, a combination of aspirin and vitamin E might be useful for the prevention of endothelial injury in cardiovascular disease, e.g. during atherogenesis.
