目的:探讨 HPV -16 E6和 E7癌蛋白对肺癌细胞 A549迁移和侵袭能力的影响及其机制。方法:A549细胞分别转染含 HPV -16 E6、E7的 EGFP 质粒,采用划痕实验观察转染后不同时间的迁移能力,Tran-swell 侵袭实验检测侵袭能力,Western blotting 和实时定量 PCR 分别分析 MMP -2和 MMP -9的蛋白、mRNA表达。结果:同对照细胞相比,转染含 HPV -16 E6、E7质粒的细胞迁移能力增强,在36h 和48h 时趋势较为明显;转染 HPV -16 E6、E7组的侵袭细胞数分别为每高倍视野121.3±13.3、129.7±5.5,其显著高于对照组(P <0.01)。而且,转染 HPV -16 E6、E7的细胞中 MMP -2和 MMP -9的蛋白和 mRNA 表达显著增加(P <0.01)。结论:HPV -16 E6和 E7癌蛋白可增强 A549细胞的迁移和侵袭能力,其机制与上调 MMP -2和MMP -9表达有关。

Objective:To study the effects of human papillomavirus (HPV)type 16 (HPV -16)oncoproteins on migration and invasion in A549 lung cancer cells and the underlying mechanisms.Methods:A549 cells were trans-fected with EGFP plasmids harboring HPV -16 E6 and E7 genes,respectively.After transfection,migration capability at different time was analyzed by wound healing assay.Invasion capability was detected by transwell invasion assay. The expression of MMP -2 and MMP -9 protein and mRNA was determined by Western blotting and real -time PCR,respectively.Results:Compared with control cells,the migration capability in the cells transfected with the plas-mids harboring HPV -16 E6 or E7 was enhanced,which was more obvious at 36h and 48h.The invasive cell number in the cells transfected with the plasmids harboring HPV -16 E6 and E7 was 121.3 ±13.3 and 129.7 ±5.5,respec-tively,which was much higher than that in control cells (P <0.01).Furthermore,the expression of MMP -2 and MMP -9 protein and mRNA in the cells transfected with the plasmids harboring HPV -16 E6 or E7 was dramatically upregulated(P <0.01).Conclusion:HPV -16 E6 and E7 oncoproteins can promote the capabilities of migration and invasion,which may be related to the upregulation of MMP -2 and MMP -9 expression.
