目的  研究miR-196b和HoxB8在結直腸癌組織中的表達及與其臨床病理特征的關系,并探討在結直腸癌組織中miR-196b與靶基因HoxB8表達的關系。
方法  用實時熒光定量PCR技術檢測30例結直腸癌組織及對應的正常黏膜組織中miR-196bmRNA和HoxB8 mRNA的表達量,用Western blot法檢測HoxB8蛋白的表達。
結果  miR-196bmRNA和HoxB8mRNA在結直腸癌組織中的表達量均高于其在對應的正常黏膜組織中的表達量(P<0.05)。miR-196bmRNA的表達與結直腸癌的淋巴結轉移、腫瘤分期(Ⅰ+Ⅱ與Ⅲ+Ⅳ)及遠處轉移均有關
(P<0.05),而與腫瘤部位、大小、大體類型、浸潤深度、組織分化程度、患者的年齡及性別均無關(P>0.05); HoxB8 mRNA的表達與結直腸癌的上述臨床病理特征均無關(P>0.05)。miR-196bmRNA與HoxB8mRNA的表達存在負相關(r=-0.458,P<0.05),而與HoxB8蛋白的表達無明顯相關性(r=-0.236,P>0.05)。
結論  miR-196b mRNA及HoxB8mRNA在結直腸癌組織中均呈高表達, miR-196b mRNA的高表達與結直腸癌的發(fā)生、發(fā)展及預后有關。miR-196b可能通過與靶基因HoxB8 mRNA的3′非編碼區(qū)結合抑制HoxB8 mRNA的表達。
