Inhibitor of transforming growth factor beta (TGF-β) type I receptor blocked O3-induced Smad2/3 phosphorylation. The levels of phosphorylated Smad2/3 (pSmad2/3) and non-phosphorylated Smad2/3 were examined by western blotting. Top panel: representative western blots; bottom panel, semiquantified data of pSmad2/3 and Smad2/3 bands. (a) Significantly different from the filtered air alone exposed control and (b) significantly different from filtered air plus IN-1233 treated group (P < 0.05, n = 3).
