摘    要:目的:探讨RNA干扰抑制人端粒酶RNA组分human telomerase RNA component,hTR)的表达时宫颈癌细胞(HeLa细胞)增殖的影响.方法:hTR基因的RNA干扰表达重组体用脂质体介导方法稳定转染HeLa细胞.RTPCR法检测hTR的mRNA表达水平,TRAP-PCR法检测端粒酶活性,MTT法检测细胞增殖.结果:RT-PCR结果表明,稳定转染RNA干扰表达重组体的细胞株,其hTR基因的mRNA抑制率较无转染对照组下降了(59.7±3.3)%,较转染空载体组下降了(56.3±4.4)%;实验组细胞端粒酶活性下降,生长速度明显减慢.结论:利用RNA干扰技术抑制hTR基因在HeLa细胞的表达能抑制该细胞端粒酶活性和增殖活性.

关 键 词:RNA干扰  HeLa细胞  人端粒酶RNA亚基  小发夹RNA

Abstract:Objective To investigate the effect of inhibiting hTR expression by RNA interference on the proliferation of HeLa cell. Methods A combination plasmids expressing shRNA specific for human telomerase RNA were transfected by Lipofectamine into HeLa cells. The inhibitory of hTR mRNA level was assayed by RT-PCR. The activity of telomerase was tested by TRAP-EB staining. The proliferation activity of HeLa cells was determined using methyl thiazolyl tetrazolium (MTT). Results As detected by RT-PCR,mRNA level of hT...
Keywords:RNAi  HeLa cell  Telomerase RNA  shRNA
