Apigenin Alleviates Liver Fibrosis by Inhibiting Hepatic Stellate Cell Activation and Autophagy via TGF-β1/Smad3 and p38/PPARα Pathways

Figure 6

Probable mechanisms of apigenin against liver fibrosis. Notes: apigenin inhibits the production of TGF-β1 in HSCs. The decrease of TGF-β1 results in the reduced activation of HSCs and downregulation of the TGF-β1/Smad3 and p38/PPARα signaling pathway, including decreased ECM production and inhibition of autophagy. Abbreviations: BDL: bile duct ligation; CCl4: carbon tetrachloride; ECM: extracellular matrix; HSCs: hepatic stellate cells.
