摘要 目的:建立一个组成性地高表达小鼠Retn基因的3T3-L1细胞系。方法:(1)采用重组DNA技术将小鼠Retn基因的全长cDNA克隆到质粒pcDNA3的CMV启动子下面而获得一个能在真核细胞内组成性表达小鼠Resistin蛋白的表达载体pcDNA3-mRetn。(2)用电穿孔转染和G418筛选等方法建立能组成性地高表达小鼠Retn基因的3T3-L1细胞系。(3)诱导细胞分化为脂肪细胞,并用实时荧光RT-PCR法分析这些脂肪细胞内Retn基因mRNA的水平。结果:构建了一个能在真核细胞内表达小鼠Retn基因的表达载体;建立了一个携带有pcDNA3-mRetn载体并组成性地高表达小鼠Retn基因的细胞系。结论:成功地建立了一个组成性地高表达小鼠Retn基因细胞系,为进一步研究Retn基因的功能和小鼠Resistin蛋白的获得奠定了基础。
