Figure 7From: Effects of PPARγ ligands on TGF-β1-induced epithelial-mesenchymal transition in alveolar epithelial cellsRegulation of TGF-β1-induced phosphorylation of Smad2 and Smad3 by PPARγ ligands. Cell lysates were prepared from A549 cells pre-treated with vehicle, RGZ (10 μM) or CGZ (10 μM) for 1 hr and then treated with TGF-β1 at the indicated concentrations for 1 hr. The Western blot is representative of 3 separate experiments.Back to article page
