Additional file 2: of Pirfenidone attenuates lung fibrotic fibroblast responses to transforming growth factor-β1

Figure S2. Effects of CTHRC1 and FHL2 knockdown on targets related to fibrotic processes in fibroblasts. Western blot analysis of targets related to fibrotic processes were assessed in CTHRC1-knocked down HFL-1 cells (A-F). The vertical axis shows the relative intensities of CTHRC1 (A), FHL2 (B), α-SMA (C), fibronectin (D), BMP4 (E), Gremlin1 (F) versus β-actin; the horizontal axis shows the conditions. Western blot analysis of targets related to fibrotic processes were assessed in FHL2-knocked down HFL-1 cells (G-L). The vertical axis shows the relative intensities of FHL2 (G), CTHRC1 (H), α-SMA (I), fibronectin (J), BMP4 (K), Gremlin1 (L) versus β-actin; the horizontal axis shows the conditions. Values represent means ± SEMs of three separate experiments. *P
