This study found that a diet high in phenylalanine and tyrosine worsened hepatic fibrosis in mice, while chitooligosaccharide (COS) supplementation alleviated it by regulating amino acid metabolism and gut microbiota.
This preclinical study investigated the role of amino acids phenylalanine (Phe) and tyrosine (Tyr) in hepatic fibrosis and the ameliorative effects of chitooligosaccharides (COS). Using a CCl4-induced mouse model, the researchers demonstrated that a diet high in Phe and Tyr exacerbated liver dysfunction and gut microbiota dysbiosis. COS supplementation alleviated hepatic fibrosis by downregulating the mTORC1 pathway and restoring gut microflora balance. Central results showed COS treatment reduced serum levels of Phe and Tyr and reversed the hyperactivation of the mTORC1 pathway. The study limitations include the need to elucidate specific COS monomers and molecular targets, and to further explore the influence of intestinal microecology. The implications suggest COS may be a potential intervention for hepatic fibrosis by regulating amino acid metabolism.
