Abstract

Resveratrol is proposed to account in part for the protective effect of red wine on the cardiovascular system. Angiotensin II (Ang II) is a potent hypertrophic stimulus in cardiomyocytes. In this study, we determined the effect of resveratrol on Ang II-induced cardiomyocyte hypertrophy. Cultured neonatal rat cardiomyocytes were stimulated with Ang II, and [ 3H]leucine incorporation and β-myosin heavy chain (β-MyHC) promoter activity were examined. Intracellular reactive oxygen species (ROS) were measured by a redox-sensitive fluorescent dye, 2′ 7′-dichlorofluorescin diacetate, and the extracellular signal-regulated kinase (ERK) phosphorylation was examined by Western blotting. Resveratrol inhibited Ang II-increased intracellular ROS levels. Furthermore, resveratrol, as well as the antioxidant N-acetyl-cysteine, decreased Ang II- or H 2O 2-increased protein synthesis, β-MyHC promoter activity, and ERK phosphorylation. In summary, we demonstrate for the first time that resveratrol inhibits Ang II-induced cardiomyocyte hypertrophy via attenuation of ROS generation.
