摘要目的探讨沉默lncRNA MAFG-AS1对人卵巢癌细胞增殖和凋亡的影响及分子机制。方法 qRT-PCR检测正常卵巢上皮细胞HOSE和3种卵巢癌细胞(SKOV3、HO8910、OVCAR3)中MAFG-AS1和miR-143-3p的表达。荧光素酶报告基因检测和qRT-PCR验证MAFG-AS1与miR-143-3p的靶向调控关系。以SKOV3细胞为研究对象,分别构建沉默MAFG-AS1或过表达miR-143-3p的卵巢癌细胞株。应用MTT法检测细胞活力,应用流式细胞术检测细胞凋亡情况,应用Western Blot检测增殖相关蛋白Cyclin D1和p21及凋亡相关蛋白Bcl-2及Bax的表达。结果与HOSE组比较,3种卵巢癌细胞中MAFG-AS1的表达显著上调,miR-143-3p的表达显著下调。pc DNA组、pc DNA-MAFG-AS1组、si-NC组、si-MAFG-AS1组miR-143-3p表达水平比较差异有统计学意义(P<0.05)。miR-143-3p是MAFG-AS1的靶基因,MAFG-AS1可负性调控miR-143-3p的表达。沉默MAFG-AS1或过表达miR-143-3p均可抑制卵巢癌细胞的增殖,促进细胞凋亡,抑制Cyclin D1和Bcl-2蛋白表达,促进p21和Bax蛋白表达。抑制miR-143-3p表达可逆转沉默MAFG-AS1对卵巢癌细胞的增殖抑制和凋亡促进作用。结论沉默MAFGAS1通过上调miR-143-3p表达可抑制卵巢癌细胞的增殖,促进细胞凋亡。
