摘要: 目的 研究埃兹蛋白(Ezrin)对原发性肝癌组织侵袭转移的影响,及其与肝癌细胞上皮间质转化(Epithelial-Mesenchymal Transition,EMT)的关系。方法 采用免疫组化maxvision法检测60例原发性肝癌组织及30例正常肝组织中Ezrin、E-cad和Vimentin的表达及关系。结果 Ezrin在原发性肝癌组织中的阳性表达率较正常肝组织高(60% vs 6.7%,P<0.01),其在肝癌中的过度表达与组织分化程度有关(P<0.05),与癌组织的大小无关(P>0.05)。上皮性标志物E-cad在肝癌组织中的阳性表达率明显低于正常癌旁组织(43% vs 76.6%,P<0.01)。间质性标志物Vimentin在肝癌组织中的阳性表达率高于正常癌旁组织(43.7% vs 0%,P<0.01)。统计学相关分析表明Ezrin与E-cad的表达呈负相关,与Vimentin的表达无相关性。E-cad与Vimentin表达呈负相关。结论 Ezrin在肝癌侵袭转移过程中发挥重要作用,并与肝癌上皮间质转化有关。

Abstract: Objective To investigate the expression of Ezrin in hepatocellular carcinoma and the relationship between Ezrin and epithelial mesenchymal transition of hepatocellular carcinoma.Methods By maxvision immunohistochemical method,we determined the expressions of Ezrin,E-cad and Vimentin and the relationship between them in 60 specimens of hepatocellular carcinoma and 30 specimens of nomal hepatic tissues.Results The positive rate of Ezrin in hepatocellular carcinoma was significantly higher than that in the normal tissue(60% vs 7%,P<0.01).The positive rate of E-cad inhepatocellular carcinoma tissue was lower than that in the normal tissue(43% vs 76.6%,P<0.01).The positive rate of Vimentin in carcinoma was higher than that in the normal tissue(43.7% vs 0%,P<0.01).Ezrin overexprossion was correlated with the clinical stage(P<0.05).The Spearman correlation analysis demonstrated that Ezrin expression wag negatively correlated with E-cad expression,while it was positively correlated with Vimentin expression.Conclusion Ezrin may play a crucial role in the progression of hepatocellular carcinoma and correlate with epithelial mesenchymal transition.
