SIRT1过表达介导PPARγ-PGC1α-NRF2通路对肥胖症大鼠肝脏脂肪沉积和变性及氧化应激的调节作用(英文)
发布时间:2021-03-23 17:30
目的:探讨沉默信息调节因子1(SIRT1)过表达介导PPARγ-PGC1α-NRF2通路对肥胖症大鼠肝脏脂肪沉积和变性及氧化应激的影响。方法:首先构建SIRT1慢病毒载体(LV),然后将大鼠随机分为4组:正常对照组(Control)、肥胖症模型组(Obesity model组)、肥胖症+SIRT1对照载体组(Obesity+LV组)和肥胖症+SIRT过表达组(Obesity+LV-SIRT1组)进行后续实验。采用卷尺测量肛鼻长并计算Lee’s指数;罗氏血糖仪检测血糖水平;全自动生化分析仪检测总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)水平;苏木精—伊红染色法(hematoxylin-eosin staining,HE)和油红O染色检测肝脏脂肪沉积和变性;采用ELISA试剂盒检测总超氧化物歧化酶(SOD)、乳酸脱氢酶(LDH)、丙二醛(MDA)和活性氧(ROS)含量;逆转录—聚合酶链反应检测过氧化物酶体增殖物激活受体γ(PPARγ)、PPARγ辅激活子1α(PGC1α)、核因子-E2相关因子2(Nrf2)m RNA水平;蛋白免疫印...
