摘要 目的探讨非小细胞肺癌(NSCLC)患者外周血清和癌组织中microRNA-21表达水平及其对肺癌细胞的侵袭和增殖影响。方法 32例NSCLC患者为研究组,30例同期肺部良性病变患者为对照组,采用Real-time RCR检测研究组肿瘤组织、癌旁组织及两组血清中microRNA-21的表达水平;此外,对肺癌细胞株A549转染microRNA-21的抑制物(inhibitor)或模拟物(mimics)后,采用transwell及CCK-8法观察microRNA-21对肺癌细胞株的侵袭及增殖的变化,并采用Western印迹检测A549中张力蛋白同源基因(PTEN)蛋白水平。结果研究组血清及肿瘤组织中microRNA-21的表达水平显著高于对照组及癌旁组织(均P<0.05);A549转染microRNA-21 mimics后细胞的侵袭和增殖能力显著增加(P<0.05),转染microRNA-21 inhibitor后,细胞的侵袭和增殖能力显著降低(P<0.05),而PTEN蛋白转染后,表达水平与上述结果相反。结论 NSCLC患者肿瘤组织和血清中高表达的microRNA-21可能通过抑制PTEN蛋白参与癌细胞侵袭和增殖能力的调节。
