Figure 2. Effects of SFN on the expression of α-SMA and fibronectin in HTFs. (A) Representative blots showing the expression of α-SMA and fibronectin. Densitometric analysis of α-SMA and fibronectin proteins normalized to GAPDH levels in (A) is shown in (B). (C) Representative bar graphs showing the relative expression of α-SMA (left panel) and fibronectin (right panel) mRNAs in differentially treated cells. Data are presented as mean ± SD (n=3). *p<0.05 compared to controls. †p<0.05 compared to cells treated with TGF-β alone.
