Effect of PEP-1-SOD1 on α-SMA and TGF-β1 protein expression. a α-SMA and TGF-β1 protein expression was detected by western blot. b Quantification of α-SMA expression by normalizing to α-Tubulin. c Quantification of TGF-β1 expression by normalizing to α-Tubulin. *P < 0.01 vs. vehicle-treated cells, ^#P < 0.01 vs. Ang II-treated cells. &P < 0.01 vs. SOD1-transduced cells n = 5
