UDP-glucuronosyltransferase (UGT) activity toward the flavonoid quercetin and UGT protein were characterized in three equidistant small intestine (SI) segments from 4-, 12-, 18-, and 28-month-old male Fischer 344 rats (n = 8/age) using villin to control for enterocyte content. SI microsomal intrinsic clearance of quercetin was increased 3- to 9-fold from 4 months in the proximal and distal SI a...
Anticonvulsants can increase the risk of developing neurotoxicity in infants; however, the underlying mechanism has not been elucidated to date. Thyroxine [3,5,3',5'-l-tetraiodothyronine (T4)] plays crucial roles in the development of the central nervous system. In this study, we hypothesized that induction of UDP-glucuronosyltransferase 1A1 (UGT1A1)-an enzyme involved in the metabolism of T4-b...
Over the last few years the genetic basis of Gilbert’s syndrome has been clarified. This issue of the journal contains four papers on this condition. One paper describes a novel molecular mechanism responsible for decreased bilirubin-UDP-glucuronosyltransferase activity, while two articles evaluate the interaction between Gilbert’s syndrome and hematologic disorders associated with increase bil...
Different pharmacokinetic properties have been observed for the two enantiomers of the entactogen 3,4-methylendioxy-methamphetamine, most probably a result of enantioselective metabolism. The aim of the present work was to study the involvement of human UDP-glucuronyltransferase (UGT) isoforms in the glucuronidation of the enantiomers of its major metabolite 4-hydroxy-3-methoxymethamphetamine (...

Currently, there are very few guidelines linking the results of pharmacogenetic tests to specific therapeutic recommendations. Therefore, the Royal Dutch Association for the Advancement of Pharmacy established the Pharmacogenetics Working Group with the objective of developing pharmacogenetics-based therapeutic (dose) recommendations. After systematic review of the literature, recommendations w...
