Fig. 4. Colony formation experiments. After ribosomal protein S15a (RPS15a) interference, BGC823 cells were grown for 2 weeks, and cell colonies were compared. 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 (*p<0.01).
