Gut microbes have been recognized to convert the human bile acids by deconjugation, dehydroxylation, dehydrogenation and epimerization of the cholesterol core, but the ability to re-conjugate them with amino acids as an additional conversion has only been recently described. These new bile acids ...

Emerging evidence suggests a link between gut microbiota, bile acid metabolism, and immune dysregulation in dyslipidemia. Through a case-control study involving 140 participants and animal experiment, we identified significantly elevated count of peripheral blood CD3+ T cells, CD4+ T cells, CD8+ ...

The global incidence of inflammatory bowel disease (IBD) is increasing, with dysbiosis of the gut microbiota identified as a significant factor contributing to chronic intestinal inflammation. This study aims to elucidate the gut microbiota and serum bile acid profiles in patients with ulcerative...

Purpose: To investigate the pathogenesis of pediatric bile reflux gastritis (BRG) using non-targeted and targeted metabolomics analyses of the changes and content differences of bile acids (BAs) in gastric juice. Methods: Data from 25 pediatric BRG patients treated at Jinhua Maternal and Child He...

Introduction:

Bariatric surgery profoundly improves type 2 diabetes (T2D); however, the specific mechanisms linking distinct procedures to metabolic benefits through bile acid (BA) remodeling remain incompletely understood. This study investigates the differential effects of single-anastomo...

BACKGROUND: Intestinal bacteria are known to regulate the bile acid (BA) homeostasis via intestinal biotransformation of BAs and stimulating the expression of fibroblast growth factor 19 through intestinal nuclear farnesoid X receptor (FXR). On the other hand, BAs directly regula...

This study investigated the regulatory effects of three probiotics (P. pentosaceus, B. coagulans, and E. faecalis) on bile acid metabolism in common carp (Cyprinus carpio) fed a high-carbohydrate-high-fat (HCHF) diet for 56 days. A targeted metabolomics approach using UHPLC-QTRAP-MS/MS with sched...

Elevated exposure to 4-hydroxyphenanthrenes (4-OHPhe) is positively associated with obesity risk. However, the specific pathogenic mechanism remains unclear. Here, we used SHapley Additive exPlanations (SHAP) and logistic regression analysis to identify a strong association between 4-OHPhe and o...
