摘要 目的:分析ABCG2(ATP-binding cassette superfamily G member2)在原发性肝细胞性肝癌(primaryhuman hepatocellular carcinoma,HCC)中的表达状况及其临床意义。方法:应用免疫组化S-P法和原位杂交的方法检测HCC150例﹑肝硬化50例﹑肝炎组织50例﹑正常肝组织10例中ABCG2蛋白及mRNA的表达情况。结果:HCC﹑肝硬化﹑肝炎和正常肝组织的ABCG2蛋白的阳性率分别是78.67%(118/150)﹑40.00%(20/50)﹑60.00%(30/50)和30.00%(3/10),四者之间差异有统计学意义(χ2=32.25,P<0.05)。ABCG2mRNA在HCC﹑肝硬化﹑肝炎和正常肝组织的阳性表达率分别是69.33%(104/150)﹑36.00%(18/50)﹑50.00%(25/50)和20.00%(2/10),差异有统计学意义(χ2=24.93,P<0.05)。结论:ABCG2在肝癌和肝炎组表达率增高,在肝硬化和正常肝组织表达率降低且ABCG2蛋白与有无转移有关,推测ABCG2参与肿瘤耐药,可能成为治疗HCC临床耐药的分子靶点。
