Effect of survivin Gene Silencing on Proliferation of Human Cervical Cancer Cell XB1702 and Their Sensitivity to Gefitinib

  • 摘要: 目的 研究survivin基因沉默对人宫颈癌XB1702细胞增殖和对化疗药物吉非替尼敏感度的影响。方法 设计合成survivin的siRNA序列,LipofectamineTM2000 转染入XB1702细胞。采用RT-PCR和Western blot检测survivin在干扰后mRNA和蛋白的表达情况,利用流式细胞仪检测细胞周期。通过MTT法和细胞克隆形成试验法观察survivin基因沉默后XB1702细胞对吉非替尼的敏感度。结果 Survivin基因沉默48 h后,XB1702细胞的survivin基因和蛋白表达明显降低,差异有统计学意义(P<0.05)。细胞周期被阻滞在G0/G1期,S期细胞数减少;差异有统计学意义(P<0.05)。survivin基因沉默组细胞对吉非替尼的敏感度显著增强。结论 survivin特异性siRNA能显著沉默XB1702细胞survivin基因,抑制细胞增殖,并增强XB1702细胞对吉非替尼的敏感度。

     

    Abstract: Objective To investigate the effect of small interfering RNA-mediated survivin knock-down on proliferation of human Cervical cancer Cell XB1702 and their sensitivity to Gefitinib. Methods The siRNA against survivin was constructed and transfected into XB1702 cells with LipofectamineTM 2000.The expression of survivin was detected by RT-PCR and Western blot.Flow cytometry was used to detect the cell cycle.Sensitivity to Geftinib after transfection were examined by MTT and clonogenic assay. Results In XB1702 cells,the protein and mRNA levels of survivin were decreased significantly after transfection,and reduction of proliferation was related to an increase in the fraction of G0/G1 phase.The sensitivity of XB1702 cells to Gefitinib increased significantly after transfection. Conclusion The survivin special siRNA silenced surviving,decreased XB1702 cells proliferation and enhanced their sensitivity to Gefitinib.
