Importance of Bile Composition for Diagnosis of Biliary Obstructions

Molecules, 2021
Determination of the cause of a biliary obstruction is often inconclusive from serum analysis alone without further clinical tests. To this end, serum markers as well as the composition of bile of 74 patients with biliary obstructions were determined to ...

Gut Mycobiota‐Associated Tryptophan Catabolites Protect Against Metabolic Dysfunction‐Associated Steatotic Liver Disease

Advanced Science, EarlyView.
ABSTRACT Accumulating evidence suggests that the intestinal microbiota participates in the progression of metabolic dysfunction‐associated steatotic liver disease (MASLD) through microbiota‐host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood.

The economy of the enterohepatic circulation of bile acids in the baboon. 2. Regulation of bile acid synthesis by enterohepatic circulation of bile acids.

Journal of Lipid Research, 1984
Isotope dilution within bile acid pools and radiochemical assessment of cholesterol oxidation to bile acids were methods used to measure short-term feedback regulation of bile acid synthesis in baboons with controlled enterohepatic circulations ...

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Quantitative estimation of the hydrophilic-hydrophobic balance of mixed bile salt solutions.

Journal of Lipid Research, 1989
This paper describes the derivation of a bile salt monomeric hydrophobicity index that quantitatively defines the composite hydrophilic-hydrophobic balance of a mixture of bile salts.

Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

Advanced Science, EarlyView.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.

Effects of monosulfate esters of taurochenodeoxycholate on bile flow and biliary lipids in hamsters.

Journal of Lipid Research, 1989
The effect of the 3 alpha- and 7 alpha-monosulfate esters of taurochenodeoxycholate on bile flow and biliary lipids was compared to the effect of unsulfated taurochenodeoxycholate. Test bile salts were infused directly into the portal circulation through

New Kids on the Block: Bile Salt Conjugates of Microbial Origin

Metabolites, 2022
Biotransformation of host bile salts by gut microbes results in generation of secondary bile salt species that have biological and physicochemical properties that are distinct from the parent compounds.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Interactions of cationic bile salt derivatives with the ileal bile salt transport system.

Journal of Lipid Research, 1975
Previous structure-activity studies of the active ileal bile salt transport system have demonstrated that a single negative charge on the side chain is essential for active transport. Furthermore, mutual inhibition studies between different pairs of bile
