ETHNOPHARMACOLOGICAL RELEVANCE: According to traditional Chinese medicine (TCM) theory, cholestasis belongs to category of jaundice. Artemisia capillaris Thunb. has been widely used for the treatment of jaundice in TCM. The polysaccharides are the one of main active components of the herb, but its effects on cholestasis remain unclear.
AIM OF THE STUDY: To investigate the protective effect and mechanism of Artemisia capillaris Thunb. polysaccharide (APS) on cholestasis and liver injury.
MATERIALS AND METHODS: The amelioration of APS on cholestasis was evaluated in an alpha-naphthyl isothiocyanate (ANIT)-induced mice model. Then nuclear Nrf2 knockout mice, mass spectrometry, 16s rDNA sequencing, metabolomics, and molecular biotechnology methods were used to elucidate the associated mechanisms of APS against cholestatic liver injury.
RESULTS: Treatment with low and high doses of APS markedly decreased cholestatic liver injury of mice. Mechanistically, APS promoted nuclear translocation of hepatic nuclear factor erythroid 2-related factor (Nrf2), upregulated downstream bile acid (BA) efflux transporters and detoxifying enzymes expression, improved BA homeostasis, and attenuated oxidative liver injury; however, these effects were annulled in Nrf2 knock-out mice. Furthermore, APS ameliorated the microbiota dysbiosis of cholestatic mice and selectively increased short-chain fatty acid (SCFA)-producing bacteria growth. Fecal microbiota transplantation of APS also promoted hepatic Nrf2 activation, increased BA efflux transporters and detoxifying enzymes expression, ameliorated intrahepatic BA accumulation and cholestatic liver injury. Non-targeted metabolomics and in vitro microbiota culture confirmed that APS significantly increased the production of a microbiota-derived SCFA (butyric acid), which is also able to upregulate Nrf2 expression.
CONCLUSIONS: These findings indicate that APS can ameliorate cholestasis by modulating gut microbiota and activating the Nrf2 pathway, representing a novel therapeutic approach for cholestatic liver disease.
