摘要 目的:探讨低硒状态下SD大鼠心肌细胞内Slc25a3基因的表达情况。方法:将24只正常成年雄性SD大鼠随机等分为低硒组和正常组。两组大鼠分别给予低硒饮食及正常饮食。饲养4周后,进行动物模型鉴定实验。采用荧光法检测两组大鼠主要脏器的硒含量、采用谷胱甘肽过氧化物酶试剂盒检测肝脏中谷胱甘肽过氧化物酶1(GPx-1)的活性、采用Realtime PCR方法检测GPx-1的mRNA水平的相对表达、采用丙二醛(MDA)测定试剂盒和超氧化物歧化酶(SOD)测试盒检测两组动物模型主要脏器中MDA含量和SOD活性;8周后,脊髓离断处死全部大鼠,取心脏组织进行下一步实验。结果:低硒组大鼠体内主要脏器硒含量均明显低于对照组,氧化应激水平明显高于对照组,心肌细胞内Slc25a3基因相对表达量明显高于对照组。结论:硒元素缺乏可以导致大鼠心肌细胞内Slc25a3基因相对表达量明显升高。
