Figure 6. Effect of Robinia pseudoacacia leaf extract (RP) on IL-1β- induced proangiogenic gene expression in HUVECs. Expression of mRNA of proangiogenic genes including (A) VEGFA, (B) FGF2, (C) ICAM1, (D) CXCL8, and (E) IL6 were determined by Q-PCR, and target gene expression level was normalized to GAPDH level using the ΔCt method. (error bars indicate±SEM; n=3; #p<0.05, ###p<0.001 compared with no-treatment control; *p<0.05, **p<0.01 compared to IL-1β–treated control).
