目的:探讨Foxp3基因对卵巢癌细胞Skov3侵袭与迁移的影响及作用机制。方法:构建Foxp3基因过表达质粒,采用脂质体转染导入Skov3细胞;以空载体转染细胞株为对照,通过细胞增殖、侵袭、RT-PCR和Western blot 实验,观察Skov3细胞Foxp3基因的表达情况,以及过表达Foxp3后细胞的侵袭与转移能力变化,检测MMP-2以及MMP-9基因表达变化。结果:导入过表达Foxp3质粒后,Skov3细胞的Foxp3表达显著升高;与空载体相比,过表达Foxp3基因显著抑制Skov3细胞的侵袭和迁移能力,并显著降低MMP-2和MMP-9蛋白表达水平。结论:上调FoxP3基因表达能通过下调MMP-2和MMP-9基因表达抑制卵巢癌细胞的增殖、侵袭、迁移行为,为深入研究Foxp3基因在体内的抑瘤作用和卵巢癌的基因治疗提供实验依据。
目的:探討Foxp3基因對卵巢癌細胞Skov3侵襲與遷移的影響及作用機製。方法:構建Foxp3基因過錶達質粒,採用脂質體轉染導入Skov3細胞;以空載體轉染細胞株為對照,通過細胞增殖、侵襲、RT-PCR和Western blot 實驗,觀察Skov3細胞Foxp3基因的錶達情況,以及過錶達Foxp3後細胞的侵襲與轉移能力變化,檢測MMP-2以及MMP-9基因錶達變化。結果:導入過錶達Foxp3質粒後,Skov3細胞的Foxp3錶達顯著升高;與空載體相比,過錶達Foxp3基因顯著抑製Skov3細胞的侵襲和遷移能力,併顯著降低MMP-2和MMP-9蛋白錶達水平。結論:上調FoxP3基因錶達能通過下調MMP-2和MMP-9基因錶達抑製卵巢癌細胞的增殖、侵襲、遷移行為,為深入研究Foxp3基因在體內的抑瘤作用和卵巢癌的基因治療提供實驗依據。

Objective:To investigate the effect of Foxp3 on the invasion and metastasis of the ovarian cancer cells Skov 3 and the related mechanism.Methods: Plasmid overexpressing Foxp 3 gene was constructed and transfected into Skov 3 cells using liposome.Proliferation,invasion,RT-PCR and Western blot analysis were done to observe the expression of Foxp 3 gene in Skov3 cells and the invasion and metastasis ability.Also,MMP-2 and MMP-9 gene expression was detected.Results:Overexpression of Foxp3 was confirmed in Skov3 cells after Foxp3 plasmid transfection.Compared with the empty vector group , overexpression of Foxp3 gene significantly inhibited the migration and invasion of Skov 3 cells.Meanwhile , the expression level of MMP-2 and MMP-9 genes were decreased.Conclusion:Upregulation of FoxP3 gene expression can inhibit cell proliferation ,invasion and migration in ovarian cancer Skov3 cells through downregulating MMP-2 and MMP-9 gene expression.This study provided experimental basis for further research on Foxp3 gene and gene therapy for ovarian cancer.
