摘要 目的探讨叉头框蛋白O1(FOXO1)表达上调对骨肉瘤细胞增殖及凋亡的影响。方法常规培养人骨肉瘤细胞系MG-63及人成骨细胞系h FOB1.19,并用qRT-PCR法检测细胞中FOXO1 mRNA表达。将MG-63细胞随机分为FOXO1重组质粒组与NC组,分别转染pc DNA3.1-FOXO1重组质粒和空载质粒。转染后24 h,分别用qRT-PCR法、Western blotting法检测细胞中FOXO1 mRNA、蛋白表达,CCK-8法检测细胞增殖能力(吸光度值),流式细胞术测算细胞凋亡率。结果人骨肉瘤细胞MG-63中FOXO1 mRNA相对表达量低于人成骨细胞h FOB1.19(P<0.05)。转染后24 h,FOXO1重组质粒组FOXO1 mRNA及蛋白相对表达量高于NC组(P均<0.05)。与NC组比较,FOXO1重组质粒组细胞增殖能力低、凋亡率高(P均<0.05)。结论 FOXO1表达上调可抑制骨肉瘤细胞增殖,促进其凋亡。
