Racial variability in the UDP-glucuronosyltransferase 1 (UGT1A1) promoter: a balanced polymorphism for regulation of bilirubin metabolism?

Proceedings of the National Academy of Sciences of the United States of America, 1998
A polymorphism in the promoter of the UDP-glucuronosyltransferase 1 (UGT1A1) gene has been shown to cause Gilbert syndrome, a benign form of unconjugated bilirubinemia.

Pharmacokinetic Prediction and Cytotoxicity of New Quercetin Derivatives

Chemistry &Biodiversity, EarlyView.
ABSTRACT Quercetin (QUE) possesses various pharmacological properties; however, its low bioavailability and solubility hinder its beneficial effects. Enzymatic glycosylation has been explored to improve these aspects. In the present study, we used a sucrose phosphorylase variant to catalyze the regioselective transglucosylation of QUE, predicted the ...

Biosynthesis of hydroxyl-linked glucuronides of short-chain bile acids by rat liver 3-hydroxysteroid UDP-glucuronosyltransferase.

Journal of Lipid Research, 1988
Microsomal preparations from livers of Sprague-Dawley rats catalyze the glucuronidation of 3 alpha-hydroxy-5 beta-H (3 alpha, 5 beta) short-chain bile acids (C20-C23), predominantly at the hydroxyl group, while the glucuronidation of 3 beta, 5 beta short-

Mutual Influence of Human Cytochrome P450 Enzymes and UDP-Glucuronosyltransferases on Their Respective Activities in Recombinant Fission Yeast

Biomedicines, 2023
Cytochromes P450 (CYPs) and UDP-glucuronosyltransferases (UGTs) are the most important human drug metabolizing enzymes, but their mutual interactions are poorly understood.

Unveiling New Triazoloquinoxaline‐Based PROTACs Designed for the Selective Degradation of the ncBAF Chromatin Remodeling Subunit BRD9

Chemistry – A European Journal, EarlyView.
We present new BRD9‐targeting degraders featuring a chemical warhead and E3 ligase ligand that distinctly differ from the typical chemical units used for BRD9 degradation. Specifically, we identified two VHL‐based PROTACs (2 and 9) based on a [1,2,4]triazolo[4,3‐a]quinoxaline scaffold that effectively and selectively degrade BRD9 and exhibit ...

Development of icterus gravis in a preterm infant with G71R UGT1A1 polymorphism [PDF]

, 2013
BACKGROUND: Uridine diphosphate-glucuronosyltransferase (UGT) gene family is involved in the detoxification of biomaterials and drugs in the liver. Among the UGT gene family members, only UGT1A1 is involved in bilirubin conjugation.

Demethylzeylasteral Exhibits Strong Inhibition towards UDP-Glucuronosyltransferase (UGT) 1A6 and 2B7

Molecules, 2012
Inhibition of UDP-glucuronosyltransferase (UGT) isoforms can result in severe clinical results, including clinical drug-drug interactions (DDI) and metabolic disorders of endogenous substances.

Inhibition of OATP1B1/3 Rather Than UGT1A1 May Be the Major Cause of the Bilirubin Elevation After Atazanavir Administration

Clinical Pharmacology &Therapeutics, EarlyView.
Atazanavir has been reported to increase total serum bilirubin level up to ninefold. It is widely believed that the observed total bilirubin elevation is primarily due to UGT1A1 inhibition. However, UGT enzymes are well‐known as a low‐affinity and high‐capacity system, and the observed drug–drug interaction mediated by UGTs is usually less than twofold.

Do Gene Polymorphisms Play a Role in Newborn Hyperbilirubinemia?

Balkan Journal of Medical Genetics
Polymorphisms of the uridine-diphospho-glucuronosyltransferase 1A1 (UGT1A1) gene, hepatic solute carrier organic anion transporter 1B1/B3 (SLCO1B1/3) gene, and glutathione S-transferase (GST) gene have been associated with significant hyperbilirubinemia ...

Identification of a Sphingolipid α-Glucuronosyltransferase That Is Essential for Pollen Function in Arabidopsis[C][W][OPEN]

The Plant Cell, 2014
This study found that IPUT1 is an enzyme required for the biosynthesis of glycosyl inositol phosphorylceramide sphingolipids in plants. These glycolipids are highly abundant and have many important cellular roles.
