摘要 目的:观察罗格列酮对氧化低密度脂蛋白(ox-LDL)诱导的系膜细胞血凝素样氧化低密度脂蛋白受体1(Lox-1)表达及其抗氧化作用。方法:培养大鼠系膜细胞,分为空白对照组、ox-LDL组、罗格列酮组和罗格列酮+ox-LDL组,培养24h后,用RT-PCR检测系膜细胞Lox-1mRNA表达情况,用分光光度比色法测定细胞上清液超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量。结果:系膜细胞中有Lox-1表达,ox-LDL诱导后表达增加,并导致系膜细胞SOD活性下降和MDA含量明显高于(分别为SOD:15.250±0.083,MDA:2.270±0.004)对照组(分别为SOD:19.950±0.079,MDA:1.250±0.002),P<0.05。罗格列酮可明显降低ox-LDL诱导引起Lox-1表达水平,P<0.05,同时也使SOD活性增加(20.060±0.082)和MDA含量(1.360±0.003)降低。结论:罗格列酮可能通过抑制ox-LDL的受体Lox-1的表达及由其引起的氧化应激,从而减轻ox-LDL对肾脏的损伤。
