CD147 specific shRNAs results in the reduction of CD147 mRNA and protein levels in SGC7901 cells. (A). Relative mRNA levels were analysed by quantitative RT-PCR. β-actin was used as normalization control. *p < 0.01 compared with SGC7901. (B). Western blot analysis of CD147 protein expressions. β-actin was used as loading control. HG:high glycosylated form; LG: low glycosylated form.
