The aim of this study was to investigate the effect of quercetin on hepatic
fibrosis, a characteristic response to acute or chronic liver injury. Mice were
randomized to bile duct ligation (BDL) or carbon tetrachloride (CCl(4)) cirrhosis
models. Quercetin (100?mg/kg or 200?mg/kg daily) was administered by gavage for 2
or 4 weeks. Liver tissue and blood samples were collected for histological and
molecular analysis. The results of our experiments showed that quercetin reduced
BDL or CCl(4) liver fibrosis, inhibited extracellular matrix formation, and
regulated matrix metallopeptidase (MMP)-9 and tissue inhibitor of
metalloproteinase (TIMP)-1. Quercetin attenuated liver damage by suppressing the
TGF-?1/Smads signaling pathway and activating the PI3K/Akt signaling pathway to
inhibit autophagy in BDL- or CCl(4)- induced liver fibrosis. Quercetin prevented
hepatic fibrosis by attenuating hepatic stellate cell activation and reducing
autophagy through regulating crosstalk between the TGF-?1/Smads and PI3K/Akt
pathways.
