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 ...

Background and aims: Elevation of conjugated primary bile acid—GCA in fecal samples was reported in IBD patients compared to healthy controls (nearly 10-fold), as well as in active ulcerative colitis (UC) patients relative to those in remission stages. Therefore we wanted to investigate the poten...

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...

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...

Bile acid profiles from fecal and serum samples of letrozole-induced PCOS mouse model treated with oligofructose. Results provide insight into the bile acid changes caused by letrzole and oligofructose.

The gut microbiome has been associated with pathological neurophysiological evolvement in extremely premature infants suffering from brain injury. The exact underlying mechanism and its associated metabolic signatures in infants are not fully understood. To decipher metab...

Gallstones are crystalline deposits in the gallbladder that are traditionally classified as cholesterol, pigment or mixed stones based on their composition. Microbiota and host metabolism variances among the different types of gallstones remain largely unclear. Here, the bile and gallstone microb...

Dyslipidemia is a major cardiovascular risk factor. While dietary phytosterols are known to lower cholesterol, the mechanisms involving the gut-liver axis are not fully understood. By integrating human clinical trials and mechanistic animal models, we demonstrate that phytosterols improve lipid p...
