From: Anti-fibrotic effects of tannic acid through regulation of a sustained TGF-beta receptor signaling
Inhibition of myofibroblast differentiation by tannic acid. a, b, Inhibition of Collagen-1 and SM-a-actin (SMA) expression by tannic acid (TA) in primary cultures of human lung fibroblasts in response to TGF-β (1 ng/ml, 48 h). Shown are the representative Western blots (a) and quantified densitometry (mean ± SD) from at least 3 independent experiments. c, Inhibition of cell force generation by tannic acid in response to TGF-β (1 ng/ml, 48 h). Shown are the results of a representative experiment performed in triplicates. *, p < 0.05 over TGF-β without TA
