Western blot analysis of TGF-β1 expression in wild type (WT), iNOS^-/-(KO) and GW274150-treated (GW) mice exposed to vehicle (C) or bleomycin (bleo) for 7 days. Representative blots are reported in a. In b, data, normalized for β-actin expression, represent mean the bleomycin induced TGF-β1 percent increase of control groups (+/- SE) of 7 independent experiments. *p < 0.05 and **p < 0.001 vs iNOSWT mice.
