【摘要】:目的研究腫瘤抑制可轉(zhuǎn)移候選基因1(TSSC1)在膠質(zhì)瘤組織中的表達(dá)及其對膠質(zhì)瘤U87細(xì)胞生物學(xué)行為的影響。方法采用Real time-PCR和Western blot檢測80例膠質(zhì)瘤(Ⅰ期25例,Ⅱ期32例,Ⅲ期15例,Ⅳ期8例)組織和瘤旁組織中TSSC1的表達(dá),采用化學(xué)合成的針對TSSC1基因的2個(gè)小干擾RNA(siRNA-TSSC1-1和siRNA-TSSC1-2)下調(diào)該基因的表達(dá),通過MTT和Transwell法分別檢測TSSC1對U87細(xì)胞增殖、遷移和侵襲的影響。結(jié)果TSSC1在膠質(zhì)瘤組織中的表達(dá)低于相應(yīng)的瘤旁組織,同時(shí)在臨床分期Ⅲ期、Ⅳ期中較Ⅰ期表達(dá)降低,將siRNA-TSSC1-1和siRNA-TSSC1-2轉(zhuǎn)染入U(xiǎn)87細(xì)胞后,U87細(xì)胞中TSSC1 mRNA和蛋白表達(dá)水平都明顯降低,細(xì)胞增殖能力顯著增強(qiáng),細(xì)胞的遷移和侵襲能力顯著增強(qiáng)。結(jié)論 TSSC1有望成為膠質(zhì)瘤早期診斷和預(yù)測預(yù)后的生物分子標(biāo)志物。
