2、和E—cadheHn的阳性率分别为81%、70%、35%;癌旁组织中zeb.1、c-jun和E.cadherin的阳性率分别为17%、25%、100%。zeb一1和c-jun蛋白在胃癌组织中的表达均显著高于癌旁组织(P<0.05)。zeb.1表达与肿瘤浸润深度、分化程度、淋巴结转移、TNM分期有关(P<0.05);与患者年龄、性别、肿块大小无相关性。c-jun表达与肿瘤分化程度有关(P<0.05),与其它临床病理特征无相关性。zeb-l与E—cadherin在胃癌组织中表达呈负相关(P<0.05),zeb.1与c-jun在胃癌组织中表达呈正相关。
3、zeb一1与c-jun高表达者术后5年生存率明显低于低表达者。结论zeb.1与c.inn高表达与胃癌的发生、发展密切相关,可作为判断胃癌预后的指标。关键词:胃肿瘤;上皮细胞一间质转化;zeb-1;e-jun;免疫组织化学中图分类号:R735.2;R36-33文献标志码:A文章编号:1001—7399(2015)O1—0048—04doi:10.13315/i.cnki.ejcep.2015.01.012Expressionofzeb-1andc-juningastriccarcinomaanditssignificanceWANGZhi—yong
