PDGFBB induced the activation of PI3K/AKT and MAPK signaling. The protein expression of ERK1/2, p-ERK1/2, AKT and p-AKT in A549 (A–C) and SPCA1 (D–F) cells after administrated with exogenous PDGFBB (20 ng/ml) or transfected with HSV-PDGFi shRNA for 48 h. shRNA: HSV-PDGFi shRNA. *P < 0.05, **P < 0.01, ***P < 0.001 by one-way ANOVA (B, C, E, F).
