中文摘要:
      目的:构建并鉴定YAP 基因短发夹干扰RNA(shRNA)慢病毒载体,建立稳定干扰YAP 基因表达的胃癌细胞株SGC7901。 方法:荧光定量PCR 检测YAP 基因在多种胃癌细胞株中的表达情况。构建重组靶向YAP 基因的shRNA 慢病毒表达质粒 PGC-shRNA-YAP,用脂质体转染的方法将载体导入胃癌细胞。经杀稻瘟菌素筛选后,建立稳定表达siRNA 的细胞株。荧光定量 PCR检测干扰效率。结果:在胃癌细胞株SGC7901中,YAP基因显示高表达。测序验证PGC-shRNA-YAP重组质粒构建成功。将 重组质粒稳定转染入胃癌细胞株SGC7901后能明显抑制YAPmRNA表达水平。结论:成功构建了PGC-shRNA-YAP慢病毒重组 质粒,建立了靶向稳定干扰YAP基因表达的siRNA胃癌细胞株SGC7901。
英文摘要:
      Objective: To construct siRNA expression vector targeting YAP gene and establish the gastric cancer cells SGC7901 with stable inhibition of YAP gene. Methods: Rea-time PCR was used to examine the YAP gene expression in sevel gastric cancer cell lines. The recombinant lentivirus PGC-shRNA-YAP vector was constructed, which was transfected into gastric cancer cells by Lipofectamine 2000. After gastric cancer cells with constant expression of the PGC-shRNA-YAP were established by blasticidin selection, the interfere efficicncy of YAP mRNA expression level was detected by real-time PCR. Results: There was high expression of YAP gene in the gastric cancer cell line SGC-7901. Recombinant lentivirus PGC-shRNA-YAP vector was successfully constructed by the identification of sequencing. The recombinant vectormarkedly inhibited the expression ofYAP gene in gastric cancer cell line SGC-7901. Conclusion: Recombinant lentivirus vector PGC-shRNA-YAP was successfully constructed and gastric cancer cell line SGC7901 with stable siRNA expression targeting YAP gene was established.
