摘要 目的探讨HMGA2在原发性肝癌中的表达及其与原发性肝癌患者临床资料间的关系。方法通过RT-PCR检测HMGA2 mRNA在肝癌组织及正常肝组织中的表达,蛋白质印迹分析、免疫组化分别检测HMGA2蛋白在肝癌组织及正常肝组织中的表达水平,分析HMGA2蛋白的表达与肝癌患者临床资料之间的相关性。结果HMGA2 mRNA在肝癌组织中的阳性表达率为43.69%,高于在正常肝组织中23.30%的阳性表达率,其在肝癌组织中的相对表达值为0.71±0.03,高于其在正常肝组织中0.28±0.04的相对表达值(P<0.05)。HMGA2蛋白在肝癌组织中的相对表达值为0.56±0.04,高于其在正常肝组织中0.19±0.03的相对表达值(P<0.05)。免疫组化结果显示HMGA2蛋白在正常肝组织中阳性表达率为20.39%,明显低于其在肝癌组织中37.86%的阳性表达率(P<0.05),HMGA2蛋白的表达与肝癌患者性别和肿瘤大小无关(P>0.05),但与淋巴结转移数量、肝内转移以及临床分期相关(P<0.05或P<0.01)。结论HMGA2在肝癌组织中高表达,且其高表达与肝癌的淋巴结转移数量、肝内转移及临床分期紧密相关,可作为肝癌转移和恶化的肿瘤标志物。
