Fig. 4. Protein levels of TGF-β, Smad3, collagen I, collagen III, and α-SMA in cardiac tissue were determined by western blotting. Immunoblotting for TGF-β, Smad3, collagen I, collagen III, and α-SMA in cardiac tissues. Bar graph showing quantification of TGF-β, Smad3, collagen I, collagen III, and α-SMA protein expression. Data are given as the mean ± SEM; n = 3 in each group. *p < 0.05 vs. DOX group.
