Figure 9. Relative expression of mRNA and the phosphorylation of protein (A) Expression of VEGFR2 in GC cells after they were transfected with negative control siRNA or VEGFR2 siRNAs (siVEGFR2-366, siVEGFR2-633 and siVEGFR2-990). (B) Expression of VEGF-A in GC cells cultured under a hypoxic condition. (C) Expression of Erk, P-Erk, Akt and P-Akt in GC cells after transfected with siRap1b or siVEGFR2 (left) Hypoxia (right) VEGF-A. (*P<0.05, **P<0.001).
