摘要 目的 研究SEPT9基因对人肝癌细胞侵袭转移的影响。方法 通过westernblot法筛选SEPT9蛋白高表达肝癌细胞系,慢病毒转染沉默后检测细胞SEPT9蛋白表达量,通过EdU染色检测sh-SEPT9对肝癌细胞增殖的影响;Transwell和划痕实验检测沉默SEPT9表达后肝癌细胞的侵袭能力和迁移能力;westernblot分析沉默SEPT9表达对肝癌细胞HIF-1α、Ki67、PCNA、MMP-9、VEGF、Vimentin, N-cadherin、E-cadherin蛋白表达影响。结果 westernblot显示SEPT9蛋白在肝癌HepG2细胞存在高表达,慢病毒转然能够获得稳定遗传的HepG2-SEPT9-shRNA细胞系,sh-SEPT9转然后,EdU染色显示HepG2细胞增殖受到明显抑制( P <0.05),细胞的侵袭能力和迁移能力显著降低( P <0.05);HepG2细胞Ki67、PCNA、Vimentin、N-cadherin、HIF-1α、MMP-9及VEGF表达量明显降低,E-cadherin的蛋白水平明显上升( P <0.05)。结论 SEPT9基因通过增强肝癌HepG2细胞的EMT机制,促进肝癌HepG2细胞的侵袭转移。
