Effect of fenoterol, rolipram, cilostamide and forskolin on TGF-β1-induced EMT makers using BEAS-2B cells. (A–D) Representative western blotting images and quantification of E-cadherin (A,C) and collagen Ӏ (B,D) in cells pre-incubated with fenoterol (A,B) or rolipram, cilostamide and forskolin (C,D) before TGF-β1 treatment. Data represent 5–6 independent experiments. Data are expressed as mean ± SEM, * p < 0.05; significant difference between indicated groups. # p < 0.05; significant difference between with or without TGF-β1 treatment.
