2、和E—cadheHn的陽性率分別為81%、70%、35%;癌旁組織中zeb.1、c-jun和E.cadherin的陽性率分別為17%、25%、100%。zeb一1和c-jun蛋白在胃癌組織中的表達(dá)均顯著高于癌旁組織(P<0.05)。zeb.1表達(dá)與腫瘤浸潤深度、分化程度、淋巴結(jié)轉(zhuǎn)移、TNM分期有關(guān)(P<0.05);與患者年齡、性別、腫塊大小無相關(guān)性。c-jun表達(dá)與腫瘤分化程度有關(guān)(P<0.05),與其它臨床病理特征無相關(guān)性。zeb-l與E—cadherin在胃癌組織中表達(dá)呈負(fù)相關(guān)(P<0.05),zeb.1與c-jun在胃癌組織中表達(dá)呈正相關(guān)。
3、zeb一1與c-jun高表達(dá)者術(shù)后5年生存率明顯低于低表達(dá)者。結(jié)論zeb.1與c.inn高表達(dá)與胃癌的發(fā)生、發(fā)展密切相關(guān),可作為判斷胃癌預(yù)后的指標(biāo)。關(guān)鍵詞:胃腫瘤;上皮細(xì)胞一間質(zhì)轉(zhuǎn)化;zeb-1;e-jun;免疫組織化學(xué)中圖分類號(hào):R735.2;R36-33文獻(xiàn)標(biāo)志碼:A文章編號(hào):1001—7399(2015)O1—0048—04doi:10.13315/i.cnki.ejcep.2015.01.012Expressionofzeb-1andc-juningastriccarcinomaanditssignificanceWANGZhi—yong
