目的:探討Livin基因在人膽管癌組織及膽管癌細(xì)胞系中的表達(dá)情況及其與膽管癌發(fā) 生發(fā)展之間的關(guān)系。方法:采用免疫組織化學(xué)技術(shù)(SP法)檢測(cè)Livin基因蛋白在45例人膽管 癌標(biāo)本及及40例癌旁膽管組織、20例正常膽管組織標(biāo)本中的表達(dá);同時(shí)采用RTPCR法及SP 法檢測(cè)了Livin基因mRNA和蛋白在人膽管癌細(xì)胞系QBC939及非腫瘤細(xì)胞系HT1080中表達(dá)。 結(jié)果:Livin在膽管癌組織中表達(dá)陽性率為57.8%,而癌旁膽管組織、非癌膽管組織中未能檢 測(cè)到Livin表達(dá)。Livin表達(dá)與性別、年齡、腫瘤大小及腫瘤分化程度無關(guān)。在有淋巴結(jié)轉(zhuǎn)組 中,Livin陽性表達(dá)率(70.4%)明顯高于無淋巴結(jié)轉(zhuǎn)移組(38.9%)。在人膽管癌細(xì)胞QBC939 中,Livin mRNA及蛋白均特異性表達(dá),而非腫瘤細(xì)胞系HT1080未見Livin表達(dá)。結(jié)論:Livin 基因在人類膽管癌組織和細(xì)胞系中選擇性高表達(dá),其可能與膽管癌發(fā)生、發(fā)展及預(yù)后密切相 關(guān)。
