The microbiome affects eukaryotic host cells via many metabolites, including the well-studied queuine as substrate for host tRNA queuosine modification...We identify the endoplasmic reticulum-localized inositol-requiring enzyme 1 (IRE1) ribonuclease as the enzyme responsible for the selective degradation of preQ1-modified tRNAs on translating ribosomes. Our results identify two microbial metabolites competing for host tRNA modification, which elicits translation quality control and impacts cell proliferation.

BGN alleviates HF through gut microbiota-dependent restoration of BA homeostasis and activation of the PPARα/CYP7A1 pathway. This study provides novel mechanistic insights into BGN's anti-fibrotic activities, positioning it as a microbiota-modulating therapeutic candidate for HF management.
