Review: microbial transformations of human bile acids

Microbiome, 2021
Bile acids play key roles in gut metabolism, cell signaling, and microbiome composition. While the liver is responsible for the production of primary bile acids, microbes in the gut modify these compounds into myriad forms that greatly increase their ...

Mutational characterization of the bile acid receptor TGR5 in primary sclerosing cholangitis. [PDF]

, 2010
TGR5, the G protein-coupled bile acid receptor 1 (GPBAR1), has been linked to inflammatory pathways as well as bile homeostasis, and could therefore be involved in primary sclerosing cholangitis (PSC) a chronic inflammatory bile duct disease. We aimed to

A proposed nomenclature for bile acids.

Journal of Lipid Research, 1992
A proposal is made for a system of nomenclature of the more common unconjugated and conjugated bile acids. Acceptable trivial names for bile acids are tabulated, and guidelines are proposed for using these existing trivial names as roots to create ...

Development and Validation of a Highly Sensitive LC-MS/MS Method for the Analysis of Bile Acids in Serum, Plasma, and Liver Tissue Samples

Metabolites, 2020
Bile acids control lipid homeostasis by regulating uptake from food and excretion. Additionally, bile acids are bioactive molecules acting through receptors and modulating various physiological processes. Impaired bile acid homeostasis is associated with

A Link between cholesterol levels and phenobarbital induction of cytochromes P450 [PDF]

, 2002
Squalestatin1 (SQ1), a potent inhibitor of squalene synthase produced a dose-dependent induction of cytochromes P450 CYP2H1 and CYP3A37 mRNAs in chicken hepatoma cells. The effect of SQ1 was completely reversed by 25-hydroxycholesterol.

Bile acids during pregnancy: Trimester variations and associations with glucose homeostasis

Health Science Reports, 2021
Background and aims Bile acids are known to contribute to hepatic glucose and lipid metabolism regulation. Although glucose homeostasis sustains well‐characterized modifications during uncomplicated pregnancies, changes in bile acids concentrations and ...

Decreased expression of breast cancer resistance protein in the duodenum in patients with obstructive cholestasis [PDF]

, 2006
Background/Aims: The expression of transporters involved in bile acid homeostasis is differentially regulated during obstructive cholestasis. Since the drug efflux transporter breast cancer resistance protein (BCRP) is known to transport bile acids, we ...

Novel microbially transformed bile acids: Biosynthesis, structure, and function

Pharmacological Research
The roles of gut microbiota and microbially modified bile acids in human health have become widely recognized. In the last five years, various microbially modified bile acids (e.g., proteinogenic amino-conjugated bile acids, polyamine-conjugated bile ...

Regulation of bile acid synthesis in the rat: relationship between hepatic cholesterol 7 alpha-hydroxylase activity and portal bile acids.

Journal of Lipid Research, 1995
Bile acid biosynthesis has been believed to be regulated by negative feedback control; however, recent experiments have cast considerable doubts on the concept. The aim of the study was to examine the consensus of the negative feedback regulation of bile

Bile Acids: Major Regulator of the Gut Microbiome

Microorganisms, 2022
Bile acids are synthesized from cholesterol and play an important role in regulating intestinal microflora. The different degrees of hydrophobicity and acidity of individual bile acids may affect their antimicrobial properties.
