Figure 8. The effects of ECSM2 knockdown on bFGF-induced ERK and FAK signaling.
(A) HUVECs were transfected with nonspecific (NS) or ECSM2 siRNAs for 72 h, starved for 8 h, and then stimulated with vehicle (-) or bFGF (10 ng/ml) for 15 min. Protein extracts were analyzed by immunoblotting with anti-pERK, anti-total ERK, anti-β-actin, anti-pFAK(Y397), anti-pFAK(S910), or anti-total FAK, as indicated. (B and C) Statistical analysis of pooled data of pERK and pFAK(Y397) from three independent experiments. Data are mean±SEM. *, P<0.05.
