摘要
目的观察不同肝癌细胞株及肝癌组织中Krfippel样因子8(KLF8)的表达,并探讨其意义。方法用逆转录-聚合酶链反应(RT—PCR)、Western blot、免疫化学方法分别检测不同肝癌细胞株及肝(癌)组织中KLF8的mRNA和蛋白质水平。结果KLF8的mRNA及蛋白质水平随肝癌细胞株侵袭转移潜能的增强而明显升高(P〈0.05);正常肝组织(6例)、无转移肝癌组织(17例)、有转移肝癌组织(6例)中KLF8mRNA的相对表达量分别为0.2377±0.0658、0.4683±0.2073、0.6669±0.0239(P〈0.05);在正常肝组织和肝硬化组织中KLF8蛋白表达的阳性率分别为16.7%(1/6)和33.3%(2/6),均为弱阳性,在肝癌组织中强阳性率为81.8%(27/33),肝癌转移灶中强阳性率为83.3%(5/6)(P〈0.01)。结论KLF8可能参与肝癌的发生和侵袭转移。
Objective To investigate the expression and role of Kruppel-like factor 8 (KLF8) in hepatocellular carcinoma (HCC). Methods The KLF8 mRNA and protein levels in different HCC cell hnes and HCC tissues were determined by RT-PCR, immunochemistry and Western blot respectively. Results Metastatic potential HCC cell lines had higher KLF8 mRNA and protein levels than primary HCC cell lines (P 〈 0.05 ). Relative KLF8 mRNA levels in normal liver tissues (6 cases), HCC tissues (17 cases) ,and recurrent HCC tissues (6 cases) were 0. 2377 ± 0. 0658,0. 4683 ± 0. 2073, and 0. 6669 ± 0.0239, respectively (P 〈 0.05 ). Metastasis specimens exhibited the highest level of KLF8 expression (5/6,83.3% strong positive) ,and primary tumor tissue specimens (27/33,81.8%) had higher level of KLF8 expression than normal ( 1/6,16.7% ) and liver cirrhosis tissue specimens ( 2/6,33.3% ), ( P 〈 0.01 ). Conclusion Abnormally activated KLF8 expression may contribute to HCC development and progression.
