MetabolomicsTargeted bile acid profiling of Faecalibaculum rodentium-induced bile acid remodeling in antibiotic-treated mice
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...

MetabolomicsMechanisms of action of bile acids in pediatric gastroesophageal reflux: Exploration through non-targeted and targeted metabolomics methods

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...

MetabolomicsBile acid is a significant host factor shaping the gut microbiome of diet induced obese mice (targeted bile acid analysis assay)

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...

MetabolomicsSADI-S and SG Surgeries Induce Distinct Bile Acid Profiles Linked to Improved Glucose Metabolism via Microbiota Interactions_feces

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...

MetabolomicsGut Microbiota and Bile Acids Profiles study of Ulcerative Colitis and Crohn's Disease Patients

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...

MetabolomicsProduction of new microbially conjugated bile acids by human gut microbiota

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 ...

MetabolomicsBile Acid Metabolome in Hepatopancreas Tissue of Common Carp

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...

MetabolomicsGut microbiota-induced perturbations in bile acids alter keratinocyte lipid metabolism via FXR-NQO1 signaling in psoriasis
Emerging evidence has shown that microbiota dysbiosis and aberrant bile acids (BAs) profiles are correlated with disease progression. This study elucidates dysregulated BAs metabolism in psoriasis patients and imiquimod-treated female mice, coupled with increased expression of the farnesoid X recept...
