1、山东医药2015年第55卷墨肝癌组织中HuR和HIF一1ot的表达及其相关性刘利平,江建新,鲍世韵。张育森,何婉(1暨南大学第二临床医学院,深圳市人民医院,广东深圳518020;2湖北省肿瘤医院)摘要:目的观察人抗原R(HuR)和缺氧诱导因子(HIF)一lot在肝癌组织中的表达变化,并探讨其相关性。方法取48例肝癌组织及癌旁组织标本,采用免疫组化染色法检测肝癌组织及癌旁组织中HuR和HIF·la蛋白的表达,采用荧光定量PCR法检测肝癌组织中HIF一1仅mRNA的表达。结果肝癌组织中HuR和HIF一1et蛋白阳性表达率分别为67%和58%,显著高于癌
2、旁组织的19%和10%(P均<0.O1)。肝癌组织中HuR与HIF一1et蛋白的表达呈正相关(r=0.723,P<0.01)。HuR蛋白高表达者中HIF一1etmRNA的表达较HuR蛋白低表达者显著上调(P<0.05)。结论肝癌组织中HuR和HIF.1et蛋白表达上调且呈正相关关系,HuR可能增强HIF一1etmRNA的稳定性,从而促进其表达。关键词:肝癌;人抗原R;缺氧诱导因子一1et;RNA结合蛋白doi:10.3969/j.issn.1002-266X.2015.18.003中图分类号:R735.7文献标志码:A文章编号:1002-266X(
