Figure 1: PPARγ expression in lung fibroblasts. (a) Western blot for PPARγ on lung fibroblasts isolated from white (W) and black (B) SSc-ILD patients and controls. Anti-β-actin antibody was used as a loading control. (b) Densitometric analysis of PPARγ in lung fibroblasts ( ) from 3 independent experiments is presented. PPARγ protein expression was adjusted in accordance with β-actin level. *Statistically significant differences.
