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 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 ...

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 ...

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.

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

Intestinal Absorption of Bile Salts

Canadian Journal of Gastroenterology, 1990
Bile acids are secreted from the liver into the duodenum where they aid in the digestion and absorption of dietary lipids. Absorption of bile acids occurs through both ionic and nonionic diffusion in the jejunum and colon and through an active sodium ion-

Bile acid solubility and precipitation in vitro and in vivo: the role of conjugation, pH, and Ca2+ ions.

Journal of Lipid Research, 1992
The principles governing the in vitro solubility of the common natural conjugated and unconjugated bile acids and salts in relation to pH, micelle formation, and Ca2+ concentration are considered from a theoretical standpoint and then correlated first ...

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

Molecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Redox regulation meets metabolism: targeting PRDX2 to prevent hepatocellular carcinoma

Molecular Oncology, EarlyView.
PRDX2 acts as a central redox hub linking metabolic dysfunction‐associated steatohepatitis (MASH) to hepatocellular carcinoma (HCC). In normal hepatocytes, PRDX2 maintains redox balance and metabolic homeostasis under oxidative stress. In contrast, during malignant transformation, PRDX2 promotes oncogenic signaling, stemness, and tumor initiation ...
