RNAi knockdown of PIK3CA preferentially inhibits invasion of mutant PIK3CA cells

Figure 5 Effect of PIK3CA silencing on tumor cell invasion. A: PIK3CA knockdown reduces invasion ability of gastric cancer cells; B: A representative result of cell invasiveness among the three groups of cells (original magnification of BGC-823 and HGC-27 cells, × 200, × 150, respectively). Con: Control group; Neg: Negative control group; Exp: Experimental group. ^bP < 0.01 vs controls, n = 3.
