This study investigated whether Faecalibaculum rodentium remodels the intestinal bile acid pool through bacterial bile salt hydrolase activity in antibiotic-treated male C57BL/6J mice. Mice were assigned to three groups: control, Faecalibaculum rodentium gavage, and Faecalibaculum rodentium gavage c...

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...

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...

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...

Targeted LC-MS metabolomic profiling was performed on plasma samples from a validation cohort comprising 20 patients with Parkinson's disease and 20 healthy controls. The study aimed to verify altered circulating bile acid levels identified in the discovery cohort, assess correlations between bil...

OBJECTIVE: To characterize the bile acid (BA) metabolomic profile of umbilical cord blood (UCB) and meconium in healthy newborns.

METHODS: Fifteen healthy newborns, which born in the Obstetrics Department of the Affiliated Hospital of Southwest Medical Univ...

Pu-erh tea displays cholesterol-lowering properties, but the underlying mechanism has not been elucidated. Theabrownin is one of the most active and abundant pigments in Pu-erh tea. Here, we show that theabrownin alters the gut microbiota in mice and humans, predominantly suppressing microbes associ...
