Fig. 2. Ribosomal protein S15a (RPS15a) expression in siRNA-transfected gastric cancer and control cells as detected by quantitative PCR. PCR analysis of RPS15a mRNA expression in BGC823 cells transfected with different siRNAs and control cells showed that the RPS15a fragments were virtually not amplified in cells treated with siRPS15a-2, which was proven to be better than siRPS15a-1 in the silencing experiments (*p<0.01). ck, normal BGC823 cells; siNC, BGC823 cells transfected with the negative control sequence; siRPS15a-1 and siRPS15a-2, BGC823 cells transfected with siRPS15a-1- and siRPS15a-2-containing siRNA, respectively.
