  • 摘要: 目的探讨HBx、Twist、E-cadherin及N-cadherin在肝细胞肝癌中的表达及意义。方法采用免疫组织化学法检测72例HBsAg阳性的肝细胞肝癌组织及癌旁组织中HBx、Twist、E-cadherin及N-cadherin的表达,并与临床病理资料做对照分析。结果HCC组织中HBx、Twist、E-cadherin及N-cadherin的阳性表达率分别为84.7%、80.6%、52.8%和45.8%,而癌旁组织的阳性表达率分别为81.9%、51.4%、70.8%和27.8%。除HBx外,后三种蛋白在肝癌组织及癌旁组织的表达差异均有显著性(P<0.05)。HBx、Twist和N-cadherin的表达升高及E-cadherin表达下降分别与有无门脉癌栓和肝外是否转移相关(P<0.05);HBx的表达分别与Twist和N-cadherin的表达呈正相关(P<0.05);HBx、Twist和N-cadherin的表达则分别与E-cadherin的表达呈负相关(P<0.05)。结论HBx、Twist和N-cadherin的高表达以及E-cadherin的低表达...
