摘要 目的通过观察法尼醇X受体在高甘油三酯血症大鼠肾脏的表达和定位,探讨脂质肾毒性的作用机制。方法将32只大鼠分为正常对照组(N组)及高果糖组(F组),每组16只。8 w及16 w时分批处死,检测各组大鼠的肾功能、空腹血糖、血脂及24 h尿微量白蛋白;检测大鼠肾皮质甘油三酯含量;油红O染色观察肾脏脂质;采用免疫组化分析法尼醇X受体表达和定位,并观察肾脏病理变化。结果与对照组比较,高果糖组血中甘油三酯和极低密度脂蛋白水平明显升高,肾组织中甘油三酯水平明显增高,肾脏病理改变加重,肾组织法尼醇X受体表达明显下调,且随时间延长而加重(P<0.05)。结论法尼醇X受体在高甘油三酯血症大鼠肾组织中表达下调,从而使肾脏脂质合成增加,进而导致肾脏损伤。
