Introduction Production of endothelin by endothelial cells depends on protein-kinase C (PKC) stimulation which has been reported to be inhibited by alpha-tocopherol (α-Toch) but not by beta-tocopherol (β-Toch). The goal of this study was to determine whether α-Toch and β-Toch inhibit endothelin secretion by endothelial cells. Methods and results In a first set of experiments, cultured bovine aortic endothelial cells (BAEC) were incubated for 48 h with 100 μmol/l α-Toch or vehicle (0.1% ethanol… CONTINUE READING
