摘　　要：目的研究shRNA靶向沉默CCDC132基因对卵巢癌SKOV3细胞增殖、迁移及侵袭的影响及其机制。方法体外培养卵巢癌SKOV3细胞株,设计CCDC132-siRNA及空转序列,转染卵巢癌SKOV3细胞,分别为sh-CCDC132组及对照组,利用qRT-PCR检测各组细胞CCDC132相对表达量,CCK8法检测细胞增殖情况,划痕实验检测细胞迁移能力,Transwell实验检测细胞侵袭能力,Western Blot法检测Wnt/β-catenin通路相关蛋白表达情况。结果转染后,sh-CCDC132组细胞中CCDC132表达水平较对照组显著降低(P<0.01);sh-CCDC132组细胞增殖率较对照组显著降低(P<0.01),迁移率下降(P<0.01)、侵袭细胞数显著降低(P<0.01),caspase-3、Bax蛋白表达显著上调(P<0.01),而β-catenin(P<0.01)、Cyclin D1(P<0.01)和c-myc(P<0.05)蛋白表达水平显著降低。结论沉默CCDC132可抑制SKOV3细胞增殖、迁移与侵袭能力,其具体机制可能与Wnt/β-catenin信号通路有关。Objective To study the effect of targeted silencing of the CCDC132 gene by shRNA on the proliferation,migration,and invasion of ovarian cancer SKOV3 cells and its mechanism.Methods Ovarian cancer SKOV3 cell line was cultured in vitro.CCDC132-siRNA and empty vector sequence were designed and transfected into ovarian cancer SKOV3 cells,which were the sh-CCDC132 group and the control group.The relative expression of CCDC132 in each group was detected by qRT-PCR.Cell proliferation was detected by CCK8 assay.Cell migration was detected by scratch assay.Cell invasion was detected by transwell assay,and Wnt/β-catenin pathway-related protein expression was detected by Western Blot.Results After transfection,the expression level of CCDC132 in the sh-CCDC132 group was significantly lower than that in the control group(P<0.01).The proliferation rate of the sh-CCDC132 group was significantly lower than that in the control group(P<0.01),the migration rate was decreased(P<0.01),and the number of invasive cells was significantly decreased(P<0.01).The expression of caspase 3 and Bax protein was significantly up-regulated(P<0.01),while the expression levels ofβ-catenin(P<0.01),Cyclin D1(P<0.01)and c-myc(P<0.05)protein were significantly decreased.Conclusion Silencing CCDC132 can inhibit the proliferation,migration,and invasion of SKOV3 cells,and the specific mechanism may be related to the Wnt/β-catenin signaling pathway.
