Abstract:
[摘 要] 目的:探讨miR-202-5p对口腔鳞状细胞癌(oral squamous carcinoma,OSCC)细胞生长、集落形成、迁移和侵袭的影响及其可能的机制。方法:通过qPCR法检测OSCC细胞系(Tca8113和SCC-4)和口腔角质细胞HOK中miR-202-5p和T细胞核因子c3(nuclear factor of activated T-cells isoform c3,NFATc3)mRNA的表达水平;将miR-202-5p mimic或/和NFATc3过表达质粒转染入Tca8113和SCC-4细胞,用MTT和集落形成实验检测转染对细胞增殖的影响,划痕伤口愈合实验和Transwell实验检测转染对细胞迁移和侵袭的影响,用Western blotting实验检测转染对NFATc3蛋白表达的影响;通过双荧光素酶报告基因实验验证miR-202-5p对候选靶基因NFATc3的直接调控作用。结果:与正常口腔角质细胞HOK相比,miR-202-5p在OSCC细胞Tca8113和SCC-4中呈低表达(均P<0.01),NFATc3 mRNA和蛋白质表达显著升高(P<0.01)。在Tca8113细胞和SCC-4细胞中,过表达miR-202-5p可显著抑制细胞生长、集落形成、迁移、侵袭以及细胞中NFATc3表达(均P<0.01)。NFATc3被证实是miR-202-5p的靶基因,过表达NFATc3能逆转miR-202-5p对OSCC细胞生长、迁移和侵袭的抑制作用。结论:miR-202-5p通过下调NFATc3表达发挥其肿瘤抑制功能,导致OSCC细胞的生长、迁移和侵袭受到抑制。
