Elevated exposure to 4-hydroxyphenanthrene (4-OHPhe) is positively associated with obesity risk. Here, the authors show that exposure to 4-OHPhe downregulates expression of hydroxylamine reductase genes in Bacteroides uniformis, leading to altered gut microbiota-bile acid-FXR axis and suppression of adipose thermogenesis.
