Multi-omics reveals an association of the gut butyrate-IDO1-tryptophan axis with Yinchenhaotang plus Zexietang-ameliorated NASH in a microbiota-dependent manner.

ABSTRACT:

Background

Nonalcoholic steatohepatitis (NASH) is a complex metabolic disorder with limited effective treatments, and its pathogenesis involves intricate crosstalk between gut microbiota, metabolism, and host signaling. Yinchenhaotang plus Zexietang (YCHZX), a traditional Chinese medicine (TCM) formulation, exhibits therapeutic potential in NASH, but its underlying mechanism-especially its interactions with the gut microbiota and metabolic networks-remains unclear.

Methods

A NASH mouse model was established via a high-fat/high-fructose/high-cholesterol diet. Mice were treated with YCHZX or its individual components (YCH, ZX). Serum biochemistry and liver histopathology were used to evaluate systemic therapeutic effects. Integrated multi-omics analyses (16S rRNA microbiome, s
