Effects of Chinese yellow wine on nitric oxide synthase and intercellular adhesion molecule-1 expressions in rat vascular endothelial cells.

Abstract：

OBJECTIVE:The objective of this study was to determine similarities in the effect of yellow wine as compared to statin and the possibility that yellow wine inhibits tumour necrosis factor-α (TNF-α)-induced nitric oxide (NO) synthesis, endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), and intercellular adhesion molecule-1 (ICAM-1) in cultured rat vascular endothelial cells (VECs). METHODS:We isolated VECs, and cultivated and purified Sprague Dawley (SD) rat thoracic aortas in vitro. We selected the optimal wine concentration using clonogenic and MTT assays to measure cell survival. Next, we divided the cells into 9 groups: (1) control, (2) TNF-α, (3) TNF-α + rosuvastatin (10 μmol/L), (4) TNF-α + ethanol 0.5%, (5) TNF-α + yellow wine 0.5%, (6) TNF-α + ethanol 1.0%, (7) TNF-α + yellow wine 1.0%, (8) TNF-α + ethanol 1.5%, and (9) TNF-α + yellow wine 1.5% and they were given the corresponding treatment for 24 h. We determined NO production with nitrate reductase. We then measured eNOS activity, and detected eNOS, iNOS, and ICAM-1 protein levels by Western blotting. RESULTS:Compared with the TNF-α group, NO production, eNOS activity, and eNOS protein expression in the rosuvastatin, and yellow wine 1.0%, and 1.5% groups were significantly increased. Protein expression of iNOS and ICAM-1 in the rosuvastatin, yellow wine 1.0%, and 1.5% groups were significantly decreased. Compared with the rosuvastatin group, eNOS, iNOS, and ICAM-1 protein expression in the yellow wine (0.5% -1.5%) groups were significantly different. CONCLUSION:Treatment with yellow wine increased NO production, eNOS activity, and eNOS protein expression, which decreases iNOS and ICAM-1 protein expression. We conclude that yellow wine may have similar beneficial effects as rosuvastatin on the cardiovascular system. These effects may be attributed to their anti-atherosclerotic actions.
