目的:探讨野黄芩素通过miRNA-496(miR-496)、基质细胞衍生因子1(SDF-1)对子宫颈癌细胞株HCC94细胞增殖及迁移能力的影响。方法:取对数生长期的HCC94细胞,分别加入20 μmol/L野黄芩素溶液(野黄芩素组)和二甲基亚砜(DMSO)(对照组)。分别采用CCK-8法和Transwell实验检测两组HCC94细胞增殖和迁移能力,实时荧光定量聚合酶链反应(qRT-PCR)检测miR-496和SDF-1 mRNA的相对表达量。采用生物信息学软件TarBase预测miR-496的靶基因,并用双荧光素酶报告基因实验进行验证。采用蛋白质印迹法检测相关蛋白的表达情况。结果:与对照组比较,培养第3、4、5天,野黄芩素组HCC94细胞增殖能力均降低(均n P<0.05)。野黄芩素组和对照组HCC94细胞的穿胶细胞数分别为(25±5)个和(134±19)个,野黄芩素组细胞迁移能力较对照组降低(n t=5.61,n P<0.01)。对照组和野黄芩素组miR-496相对表达量分别为1.07±0.12和11.24±2.75,差异有统计学意义(n t=3.68,n P<0.01)。双荧光素酶报告基因实验结果证实SDF-1是miR-496的下游靶基因。野黄芩素组和对照组HCC94细胞中SDF-1 mRNA相对表达量分别为0.29±0.05和1.01±0.07,差异有统计学意义(n t=7.22,n P<0.01)。与对照组比较,野黄芩素促进miR-496表达后,SDF-1蛋白、细胞增殖蛋白细胞周期蛋白依赖激酶3(CDK3)、细胞迁移蛋白Slug和Zeb-2表达均降低。n 结论:野黄芩素可通过miR-496-SDF-1轴抑制子宫颈癌HCC94细胞的增殖及迁移。“,”Objective:To explore the effects of scutellarein on the cell proliferation and migration of cervical cancer cell line HCC94 through miRNA-496 (miR-496) and stromal cell-derived factor 1 (SDF-1).Methods:HCC94 cells in the logarithmic growth phase were taken as objects, and 20 μmol/L scutellarin solution (scutellarin group) and dimethyl sulfoxide (DMSO) (control group) were added respectively. The CCK-8 method and Transwell experiment were used to detect the proliferation and migration ability of the two groups of HCC94 cells. The relative expression levels of miR-496 and SDF-1 mRNA were detected by real-time quantitative polymerase chain reaction (qRT-PCR). The target gene of miR-496 was predicted by the bioinformatics software TarBase and verified by the dual-luciferase reporter gene assay. Western blot was used to detect the expression of related proteins.Results:Compared with the control group, the proliferation ability of HCC94 cells in the scutellarin group was decreased on the 3rd, 4th and 5th day of culture (all n P < 0.05). The number of HCC94 cells in the scutellarin group and the control group were 25±5 and 134±19, respectively, and the cell migration ability of the scutellarin group was lower than that of the control group ( n t = 5.61, n P < 0.01). The relative expressions of miR-496 in the control group and the scutellarin group were 1.07±0.12 and 11.24±2.75, respectively, and the difference was statistically significant ( n t = 3.68, n P < 0.01). The dual-luciferase reporter gene assay confirmed that SDF-1 was the downstream targeted gene of miR-496. The relative expressions of SDF-1 mRNA in the scutellarin group and the control group were 0.29±0.05 and 1.01±0.07, respectively, and the difference was statistically significant ( n t = 7.22, n P < 0.01). Compared with the control group, after scutellarin promoted the expression of miR-496, the expressions of SDF-1 protein, the cell proliferation protein cyclin-dependent kinase 3 (CDK3) and the cell migration proteins Slug and Zeb-2 were decreased.n Conclusions:Scutellarin could inhibit the proliferation and migration of cervical cancer HCC94 cells through the miR-496-SDF-1 axis.
