摘要 目的通过建立高脂饮食诱导的小鼠肥胖模型筛查网膜脂肪组织中诱发脂类代谢紊乱相关m icroRNA的差异性表达。方法 20只小鼠随机分为正常饮食组和高脂饮食组,喂养8 w后处死,测量小鼠体重、网膜脂肪组织重量,并检测血脂水平,同时取网膜脂肪组织常规抽提总RNA,采用含有468个microRNA的芯片检测系统进行m icroRNA表达谱的差异分析。结果高脂饮食组小鼠的体重和网膜脂肪组织重量均显著高于正常饮食组,甘油三酯(TG)和总胆固醇(TC)水平显著高于正常饮食组;与正常饮食组相比,高脂饮食组小鼠网膜脂肪组织m icroRNA表达谱中明显差异表达的microRNA共有15个,其中m iR-191、miR-130 a、miR-107、miR-143、miR-122、miR-130b、miR-103、miR-17-92、miR-19b表达上调,miR-138、miR-14、miR-20、miR-341、miR-198 a、miR-93表达下调。结论在小鼠肥胖模型中,部分网膜脂肪组织的microRNA表达发生了明显变化,提示microRNA可能参与肥胖诱发的脂类代谢紊乱的调节作用。
