Identification of a Functional CYP2C8 Variant Allele that Alters Splicing, Reduces Protein Expression, and Increases Drug Exposure

Clinical Pharmacology &Therapeutics, EarlyView.
This study investigated genetic determinants of the pharmacokinetics of the CYP2C8 index drugs repaglinide and gemfibrozil, and their interaction in healthy participants. Sequencing data from a study with montelukast revealed a novel functional CYP2C8 allele (rs2071426, CYP2C8*19), predicted to create an intronic splice donor site.

Integrated assessment of rifampicin‐mediated induction of transporters and drug‐metabolizing enzymes in a long‐term human liver tissue chip system

Clinical Pharmacology &Therapeutics, EarlyView.
Rifampicin is a prototypical clinical inducer used in drug–drug interaction (DDI) studies. However, the clinical relevance and predictability of rifampicin‐mediated hepatic transporter induction remain poorly defined. Conventional hepatocyte culture models fail to capture clinically relevant regulation of transporters and drug‐metabolizing enzymes ...

Is Ceftriaxone-Induced Biliary Pseudolithiasis Influenced by UDP-Glucuronosyltransferase 1A1 Gene Polymorphisms?

Case Reports in Medicine, 2011
Ceftriaxone (cfx), a third-generation cephalosporin antibiotic, leads to transient cholelithiasis in some children, also known as pseudolithiasis. However, the underlying pathogenetic mechanism of this adverse effect has not yet been elucidated.

A translational multimodal machine‐learning prototype predicting valproate response in epilepsy treatment

Epilepsia, EarlyView.
Abstract Objective Epilepsy affects ~1% of the global population and often requires lifelong antiseizure medication (ASM) therapy. Valproic acid (VPA) is a commonly prescribed first‐line ASM, yet only approximately half of patients achieve sustained seizure freedom. Treatment selection remains largely empirical.

Prevalence of UDP-glucuronosyltransferase polymorphisms (UGT1A6∗2, 1A7∗12, 1A8∗3, 1A9∗3, 2B7∗2, and 2B15∗2) in a

Saudi Pharmaceutical Journal, 2017
Glucuronidation is an important phase II pathway responsible for many endogenous substances and drug metabolism. The present work evaluated allele frequencies of certain UDP-glucuronosyl-transferases (UGT 1A6∗2, A7∗12, A8∗3, A9∗3, 2B7∗2, and 2B15∗2) in ...

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

Epilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...

G‐quadruplex‐enhanced circular single‐stranded DNA (G4‐CSSD) adsorption of miRNA to inhibit colon cancer progression

Cancer Medicine, 2023
Background Chromosomal heterogeneity leads to the abnormal expression and mutation of tumor‐specific genes. Drugs targeting oncogenes have been extensively developed.

[UDP-glucuronosyltransferase].

Nihon eiseigaku zasshi. Japanese journal of hygiene, 2002
UDP-glucuronosyltransferases (UGTs) represent a family of enzymes that glucuronidate many internal substances and drugs. This family acts as a drug metabolism phase II reactor in the liver and comprises one of the major protective mechanisms from toxic chemical substances. UGTs have two subfamilies; UGT1 and UGT2.

DPYD and UGT1A1 Genotype‐Based Dosing for Fluoropyrimidines and Irinotecan Chemotherapy: Variant‐Specific Impact on Treatment Intensity and Toxicity

International Journal of Cancer, EarlyView.
Pre‐treatment DPYD and UGT1A1 genotyping is increasingly used to prevent fluoropyrimidine‐ and irinotecan‐related toxicity, but variant‐specific real‐world effects remain unclear. In an unselected cohort of cancer patients with actionable genotypes, genotype‐driven dosing improved safety while preserving treatment exposure in high‐risk DPYD c.1905+1G>A

Serum bilirubin affects graft outcomes through UDP-glucuronosyltransferase sequence variation in kidney transplantation.

PLoS ONE, 2014
BackgroundOxidative stress is a major mediator of adverse outcome after kidney transplantation. Bilirubin is produced by heme oxygenase-1 (HO-1), catalyzed by UDP-glucuronosyltransferase (UGT1A1), and has potential as an antioxidant.
