摘要 目的研究含硒蛋白TRXR-1、TRXR-2、GPX1和GPX4在人体结肠癌组织不同病理阶段的表达水平。方法收集32名结肠癌患者行左半结肠切除术的新鲜组织(每个病期8名患者),作为对照的正常组织来自切除物的无癌部分。对同一样本使用ELISA,实时PCR和免疫组织化学(实时PCR和免疫组织化学技术仅用于T3和T4期肿瘤样本)3种方法检测。数据结果采用SPSS软件(10.0.7版本)和REST软件进行统计分析。结果结肠癌组织中的TRXR-1随着病情的恶化而升高,而正常组织与肿瘤组织的TRXR-2蛋白在任何时期的表达水平差异均不显著。与正常组织作比较,所有肿瘤组织的GPX1水平均升高;除T3期肿瘤组织外,其他病期肿瘤组织GPX4的表达水平比之正常组织显著上调。结论含硒蛋白在维持肿瘤细胞生存中起关键作用,可成为抗癌药物开发的潜在方向。
