摘要 目的探讨生物钟基因同期蛋白Per家族(Per1、Per2、Per3)在肝内胆管癌发生发展中的作用。方法采用免疫组化法检测60例肝内胆管癌患者癌组织及癌旁组织中Per1、Per2、Per3蛋白的表达,分析三者与肝内胆管癌患者临床病理特征的关系。结果肝内胆管癌组织、癌旁组织Per1蛋白阳性表达率分别为41.7%、93.3%,Per2蛋白阳性表达率分别为31.7%、88.3%,Per3蛋白阳性表达率分别为43.3%、91.7%,肝内胆管癌组织中Per1、Per2及Per3蛋白的阳性表达率均低于癌旁组织(P均<0.05)。肿瘤直径≥5 cm者Per2、Per3蛋白的阳性表达率低于直径<5 cm者(P均<0.05)。肿瘤组织有血管侵犯者Per2、Per3蛋白的阳性表达率低于无血管侵犯者(P均<0.05)。结论 Per1、Per2及Per3蛋白在肝内胆管癌组织中表达均降低,可能与肝内胆管癌的发生发展有关。
