Fig. 1From: IL-27 inhibits the TGF-β1-induced epithelial-mesenchymal transition in alveolar epithelial cellsEffects of IL-27 and TGF-β1 on A549 cells. a A549 cells were treated with various concentrations of IL-27 for 48 h. Cell proliferation was analysed in an MTT assay. b A549 cells were treated with various concentrations of IL-27 and TGF-β1. Protein levels of E-cadherin and vimentin were measured by a western blot. For subsequent experiments 100 ng/ml of IL-27 and 40 ng/ml of TGF-β1 were used. Values are expressed as the mean ± SD from at least three experiments. Statistical significance was assessed by one-way ANOVA and Tukey’s post hoc test. Compared with control *P < 0.05; **P < 0.01; ***P < 0.001Back to article page
