摘要: 摘 要 目的:探讨错配修复基因hMLH1在雌激素诱导结肠癌细胞凋亡中的作用。方法:将含野生型hMLH1-cDNA的质粒转入hMLH1缺陷的人结肠癌细胞株HCT116,在不同浓度的雌激素干预下,分别以流式细胞仪和活细胞计数试剂盒(cell counting kit-8)法检测转染后细胞的凋亡率和活性。结果:与空载组相比,转染hMLH1后雌激素能明显诱导HCT116细胞活性降低,且凋亡率增加。结论:hMLH1参与雌激素诱导的结肠癌细胞株HCT116凋亡。

Abstract: Abstract: Objective Exploring the role of mismatch repair gene hMLH1 played in the estrogen-induced colon cancer cell apoptosis. Methods: Transmit wild-type hMLH1-cDNA plasmid into hMLH1-deficient colon cancer cells (HCT116 cells) then treat cells with different concentrations of estrogen. Detect the rate of apoptosis and the activity of cells with flow cytometry and cell counting kit-8 respectively; Results:With the no-transfection group compared, after transfection , Estrogen can decreased the the activity and increase the apoptosis rate of HCT116 cells obviously .Conclusion: hMLH1 is involved in estrogen-induced apoptosis of colon cancer cell line HCT116.
