Abstract | Ulcerative colitis (UC) is characterized by overactive inflammatory response, impaired intestinal mucosal barrier and disrupted gut microbiota. Youhua Kuijie formula is a classic empirical prescription based on the pathogenesis of UC. The present study was designed to verify the protective effect of Youhua Kuijie Formula on DSS-induced UC in mice and uncover the related mechanism. Youhua Kuijie Formula were orally administrated to UC mice induced by DSS dissolved in drinking water for ten days. The protective effect of Youhua Kuijie Formula was evidenced by reduced pathological symptoms accompanied by palliative inflammatory response and relatively intact intestinal barrier. The data from 16S rRNA gene sequencing and GC-MS untargeted metabolomics indicated that the supplement of Youhua Kuijie Formula restructured gut microbiota community structure, and thereby modulated the metabolic profiles in UC mice. The analysis of pathway enrichment analysis suggested the major alterations in metabolic pathway were related to protein digestion and absorption. Besides, the results of the following experiments suggested that Youhua Kuijie Formula treatment increased adenosine monophosphate-activated protein kinase (AMPK) activation, decreased mechanistic target of rapamycin (mTOR) phosphorylation, and thereby reversing autophagy deficiency in the intestinal tract of UC mice. Collectively, our results demonstrated that the regulation of AMPK/mTOR was involved in Youhua Kuijie Formula administration mediated protective effect on UC. |
