摘要: 目的 研究氨基甲酰磷酸合成酶1(CPS1)在喉鳞癌患者组织中的表达水平及与临床病理指标的相关性,探讨CPS1对喉鳞癌的临床意义。 方法 采用逆转录实时定量聚合酶链反应(RT-qPCR)及Western blot免疫印迹技术,分别检测喉鳞癌组织及癌旁组织中CPS1 mRNA及蛋白表达水平,同时采用免疫组织化学法检测 CPS1在喉鳞癌组织中的表达水平及其结构中的分布情况。 结果 RT-qPCR 和Western blot结果显示,与癌旁组织相比,喉鳞癌组织CPS1 mRNA 和蛋白表达明显增高,表达差异有统计学意义(P<0.01);免疫组化结果显示CPS1表达与肿瘤分化程度、临床分期、淋巴结转移等因素密切相关(P<0.05),而与患者年龄、性别、吸烟史、饮酒史及肿瘤部位无关(P>0.05)。 结论 在喉鳞癌组织中CPS1的mRNA和蛋白表达明显升高,且与临床进展密切相关,说明CPS1在喉癌发生及转移过程中起到一定的作用,可能作为喉癌诊断的重要指标。
