Abstract
目的:构建CD147-shRNA重组质粒并检测其对胃癌细胞SGC7901内源性CD147表达的抑制作用。方法:构建靶向CD147的siRNA表达载体pSilencer-CD147siRNA,稳定转染至SGC7901细胞中,通过Real-time PCR和Western blot法检测转染细胞中CD147表达水平的变化。结果:酶切鉴定和测序证实成功构建pSilencer-siRNA1,pSilencer-siRNA2和pSilencer-negative,转染后SGC7901中CD147表达水平显著降,而以pSilencer-siRNA2抑制作用最为显著。结论:构建pSilencer-CD147siRNA成功,并筛选出基因抑制效果抑制最佳的pSilencer-siRNA2,为进一步实验打下了基础。
