1、重庆医学2014年7月第43卷第20期2603论著·临床研究doi:10.3969/j.issn.1671—8348.2014.2O.022Bcl一6共抑制因子样蛋白及E钙黏蛋白在胃癌中的表达及相关性分析王金泗,陈晓耕,林孟波(福建省立医院肿瘤外科,福州350001)摘要:目的检测Bcl一6共抑制因子样蛋白1(BC0RLI)及E钙黏蛋白(E-cadherin)在胃癌及对应的癌旁组织中的表达情况,分析二者表达的相关性。方法收集58例胃癌及对应癌旁组织,运用免疫组织化学技术检测BCORL1及E-cadherin的表
2、达情况,分析二者表达的相关性。结果BCORL1在胃癌组织中的表达显著高于对应的癌旁组织(6O.3vs.17.2,P一0.000),而E-cadherin在胃癌组织中的表达显著低于对应的癌旁组织(27.6vs.63.8,P一0.000);BCORL1及E—cadherin表达与肿瘤组织病理分化、浸润深度、淋巴结转移和TNM分期相关(P<0.05);胃癌组织中BCORL1与E-cadherin表达呈负相关(r=一0.571,P=0.002)。结论胃癌组织中BCORL1高表达与恶性临床病理参数相关,并与E-cadhe
3、rin表达呈负相关,提示BC0RL1可能通过转录抑制E-cadherin,促进胃癌进展和转移。关键词:胃肿瘤;Bcl-6共抑制因子样蛋白1;E钙黏蛋白;侵袭转移;临床意义中图分类号:R735.2文献标识码:A文章编号:1671—8348(2014)2O一2603—03TheexpressionofBCORL1andE-cadheriningastriccarcinomaandtheircorrelationanalysisWangJinsi,ChenXiaogeng,LinMengbo(Departmentof
