The UDP-glucuronosyltransferases (UGTs) are integrally involved in the clearance of a wide range of drugs used to combat human diseases. UGT expression levels and activity can be induced by drug addition to cells and has been proposed as a potential intratumoral drug resistance mechanism. Traditional methods of assaying UGT activity are drug-centri...

Identification of genetic polymorphisms that contribute to the risk of developing cancers is important for cancer prevention. The most recent human genome GRCh38/hg38 assembly (2013) reveals thousands of genetic polymorphisms in human uridine diphosphoglucuronosyltransferase (UGT) genes. Among these, a large number of polymorphisms at the UGT1A and...
Human UDP-glucuronosyltransferases (UGTs) are major phase II enzymes in the drug metabolism system. Despite major advances in characterization of UGT gene family members, their role in clearance and homeostasis of endogenous substrates is insufficiently understood. Endobiotic substrates including bilirubin, serotonin, eicosanoids, steroid hormones,...
Nuclear receptor humanized mice models have been developed to predict regulation of drug metabolizing enzyme by xenobiotics. However, limited information is available concerning xenobiotic-induced regulation of drug metabolizing enzymes in multiple nuclear receptor humanized mice. The present study investigated the hepatic regulation of cytochrome ...
Xenobiotics may interfere with the hypothalamic-pituitary-thyroid endocrine axis by inducing enzymes that inactivate thyroid hormones and thereby reduce the metabolic rate. This induction results from an activation of xeno-sensing nuclear receptors. The current study shows that benzo[a]pyrene, a frequent contaminant of processed food and activator ...

Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers worldwide with poor prognosis. Thus, identification of predictive biomarkers for early diagnosis and intervention is needed to improve patients' survival. Research shows that heritable mutations, such as single nucleotide polymorphisms (SNPs), contribute to human cancer sus...

Esophageal cancer (EC) is one of the most common malignancies in low- and medium-income countries and represents a disease of public health importance because of its poor prognosis and high mortality rate in these regions. The striking variation in the prevalence of EC among different ethnic groups suggests a significant contribution of population-...

Capsaicin was subjected to significant hepatic glucuronidation, wherein UGT1A1 and 2B7 were the main contributing enzymes.
Polychlorinated dibenzo-p-dioxins (PCDDs) and coplanar polychlorinated biphenyls (PCBs) contribute to dioxin toxicity in humans and wildlife after bioaccumulation through the food chain from the environment. The authors examined human and rat cytochrome P450 (CYP)-dependent metabolism of PCDDs and PCBs. A number of human CYP isoforms belonging to t...
