摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗通过体外实验,探讨DNAJC6在肝细胞肝癌进展中的作用途径。
〖HTH〗方法〖HTSS〗〖KG*2〗应用体外肝癌细胞培养、质粒构建、转染及逆转录-聚合酶链反应检测肝癌细胞HepG2中DNAJC6表达对上皮-间质转变(epithelialtomesenchymal transition,EMT)过程的影响。
〖HTH〗结果〖HTSS〗〖KG*2〗与对照组比较,转染DNAJC6后的肝癌细胞HepG2中EMT相关转录因子Twist1、Snail、Slug、ZEB1表达水平明显升高(P<001),间质细胞标记物神经-钙黏素(Ncadherin)和波形蛋白(Vimentin)表达上调(P<001),上皮标记物上皮-钙黏素(Ecadherin)和上皮细胞紧密连接蛋白(ZO1)表达下调(P<001)。
〖HTH〗结论〖HTSS〗〖KG*2〗DNAJC6通过诱导EMT过程参与肝细胞肝癌的进程。

Abstract: [Abstract] Objective〖HTSS〗〓To investigate the role of DNAJC6 in the progression of hepatocellular carcinoma in vitro.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The effects of DNAJC6 expression on epithelialtomesenchymal transition(EMT) in HepG2 cells were detected by in vitro liver cancer cell culture, plasmid construction, transfection and reverse transcriptionpolymerize chain reaction.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Compared with the control group,the expression level of EMT related transcription factor in hepatocellular carcinoma cell line HepG2 transfected with DNAJC6 Twist1, Snail, Slug, ZEB1 was increased significantly(P<001). Mesenchymal cell markers Ncadherin and vimentin were upregulated(P<001). Epithelial markers Ecadherin and ZO1 were downregulated(P<001).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓DNAJC6 is involved in the process of hepatocellular carcinoma by inducing EMT.
