  目的:分析糖尿病长爪沙鼠5种组织中ND3基因在mRNA和蛋白水平的表达,以期探索长爪沙鼠糖尿病模型中ND3的作用和靶器官。方法 选取血糖正常对照组沙鼠和糖尿病实验组沙鼠各6只,分别采集动物的肾脏、肝脏、骨骼肌、脑和心脏组织,采用Q-PCR和Western blotting方法检测ND3在各组织中mRNA和蛋白水平表达状况。结果 与对照动物相比,糖尿病长爪沙鼠ND3基因的mRNA表达水平在肾脏组织中极显著升高,肝脏和肌肉组织中则显著降低,脑组织中仅有降低趋势,而在心脏组织中仅有升高趋势。检测蛋白水平发现除心脏组织外,其他组织均与mRNA水平表达结果一致。结论 肾脏组织是糖尿病长爪沙鼠ND3基因作用的主要部位,同时在其他4种组织中该基因也发挥着一定作用。
