TGF-β stimulated the expression of PRMT1 and PGC-1α. (A) Representative Western blots of the kinetic for TGF-β–stimulated expression of C/EBPβ, PRMT1, and PGC-1α in primary fibroblast from controls (n = 3) and asthma patients (n = 3). Protein band density of (B) C/EBPβ, (C) PRMT1, and (D) PGC-1α was measured by ImageJ software, and the relative expression was normalized to GAPDH. The results were expressed as mean ± SEM. Comparison of unstimulated control fibroblasts to other groups by Mann–Whitney U test: *p < 0.05, **p < 0.01. Comparison of unstimulated asthmatic fibroblasts to TGF-β1 stimulated cells: ^p < 0.05.
