Abstract

Incidence of diabetes mellitus is dramatically growing in the world. Oxidative stress, advanced glycation end products (AGEs) and receptor for AGE (RAGE) play key role in the pathogenesis of diabetes. Little is known about resveratrol effects on the liver. We hypothesize that resveratrol may exert a hepatoprotective effect in diabetic rats. Male rats with diabetes were treated with or without resveratrol at 1, 5 and 10 mg/kg body weight for 30 days. Total AGEs and malondialdehyde (MDA) levels in liver tissues were determined by spectrofluorimetric methods. Total antioxidant capacity and total oxidant contents in the liver and glucose in plasma were measured by a colorimetric assay. Expression of RAGE was assayed in liver of all animals using quantitative polymerase chain reaction. In liver tissue extract of resveratrol-treated rats with diabetes, MDA levels, total oxidant, plasma glucose and expression of RAGE were significantly reduced compared to the untreated group. Moreover, total antioxidant levels were significantly increased in treated rats. There was no significant difference in AGE contents among all groups. These results revealed that resveratrol had beneficial effects on the liver by extenuating oxidative stress and down regulation of RAGE expression.

摘要

糖尿病的发病率在全球范围内呈显著上升趋势。氧化应激、晚期糖基化终产物(AGEs)和 AGE 受体(RAGE)在糖尿病的发病机制中发挥着关键作用。关于白藜芦醇对肝脏的影响知之甚少。我们假设白藜芦醇可能对糖尿病大鼠具有肝保护作用。雄性糖尿病大鼠分别用 1、5 和 10mg/kg 体重的白藜芦醇处理 30 天。通过分光荧光法测定肝组织中总 AGEs 和丙二醛(MDA)的含量。通过比色法测定肝和血浆中总抗氧化能力和总氧化剂含量以及血浆葡萄糖水平。使用定量聚合酶链反应测定所有动物肝组织中 RAGE 的表达。与未治疗组相比,糖尿病白藜芦醇治疗大鼠的肝组织提取物中 MDA 水平、总氧化剂、血浆葡萄糖和 RAGE 表达显著降低。此外,治疗组的总抗氧化水平显著升高。各组之间的 AGE 含量没有显著差异。这些结果表明,白藜芦醇通过减轻氧化应激和下调 RAGE 表达对肝脏具有有益作用。
