Astragaloside Inhibits Hepatic Fibrosis by Modulation of TGF-β1/Smad Signaling Pathway

Figure 5

Astragalosides decreased the levels of collagen-related indicators and α-SMA in liver tissues. (a) By assay of ELISA and real-time PCR, AST was found to decrease the expression of COL-I induced by CCL4 in rats. (b-c) By assay of ELISA and real-time PCR, AST was also found to decrease the expression of COL-III and α-SMA. AST: astragalosides; LY-364947: TGF-β receptor 1 inhibitor. The values presented are the means ± SD ( in each group). and versus control group; and versus model group (CCL4).
