title: Resveratrol Protects against High-Fat Diet Induced Renal Pathological Damage and Cell Senescence by Activating SIRT1.
abstract: Obesity-related renal diseases have been a worldwide issue. Effective strategy that prevents high fat-diet induced renal damage is of great significance. Resveratrol, a natural plant polyphenol, is famous for its antioxidant activity, cardioprotective effects and anticancer properties. However whether resveratrol can play a role in the treatment of renal diseases is unknown. In this study, we added resveratrol in normal glucose or high glucose medium and provide evidences that resveratrol protects against high-glucose triggered oxidative stress and cell senescence. Moreover, mice were fed with standard diet, standard diet plus resveratrol, high-fat diet or high-fat diet plus resveratrol for 3 months, and results show that resveratrol treatment prevents high-fat diet induced renal pathological damage by activating SIRT1, a key member in the mammalian sirtuin family that response to calorie restriction life-extension method. This research confirms the potential role of resveratrol in the treatment of renal diseases and may provide an effective and convenient method to mimic the beneficial effects of calorie restriction.
