Effect of catalytic antioxidant treatment on SM-mediated increase in bronchoalveolar lavage fluid (BALF) TGFβ1 levels. Concentrations of the pro-fibrotic growth factor TGFβ1 were quantified in BALF samples at 24 h post-exposure to SM using conventional ELISA. Data is presented as mean ± SEM. Two-way ANOVA with Newman–Keuls post-test corrected for multiple comparisons was performed to determine differences between groups, bars with different letters are significantly different from one another (P < .05). Sham PBS n = 17, Sham 10150 n = 19, SM PBS n = 8, SM 10150 n = 7.
