Androgens and estrogens play major roles in cell differentiation, cell growth, and peptide secretion in steroid target tissues. In addition to the binding of these hormones to their receptors, formation and metabolism are important in the action of steroids. Metabolism of the potent steroid hormones includes glucuronidation, a major pathway of steroid(More)
Genetic polymorphisms occur in many of the drug metabolizing enzymes. However, the effect of polymorphisms in the genes encoding phase II drug metabolizing UDP-glucuronosyltransferases is still undescribed, despite the many reported cases of variations in glucuronidation activities. Characterization of the UGT2B15(Y85) cDNA, which was isolated from human(More)
UNLABELLED UDP-glucuronosyltransferase 1A1 (UGT1A1) is involved in a wide range of biological and pharmacological processes because of its critical role in the conjugation of a diverse array of endogenous and exogenous compounds. We now describe a new UGT1A1 isoform, referred to as isoform 2 (UGT1A1_i2), encoded by a 1495-bp complementary DNA isolated from(More)
In recent years, the enzymes which are involved in the formation of DHT in steroid target tissues have been well investigated, however, enzymes responsible for the catabolism and elimination of steroids in these tissues, in particular the uridine diphospho-glucuronosyltransferase (UGT) family of enzymes, have received much less attention. We have recently(More)
BACKGROUND & AIMS Cirrhotic patients admitted to an Intensive Care Unit (ICU) have a poor prognosis. Identifying patients in whom ICU care will be useful can be challenging. The aim of this study was to assess the predictive value of prognostic scores with respect to mortality and to identify mortality risk factors. METHODS Three hundred and seventy-seven(More)
UGT2B17 is a UDP-glucuronosyltransferase enzyme expressed in several extrahepatic steroid target tissues, including the human prostate, where it glucuronidates C19 steroids such as dihydrotestosterone (DHT), androsterone (ADT), and androstane-3alpha, 17beta-diol (3alpha-diol). To determine if UGT2B17 is regulated by physiological effectors of the human(More)
UNLABELLED After liver transplantation (LT), postoperative pulmonary complications (PPC) occur in approximately 35% to 50% of the recipients. Among these PPC, pneumonia is the most frequently encountered. Pulmonary dysfunction has also been widely reported among patients awaiting LT. The links between this dysfunction and PPC have not been clearly(More)
We studied whether polymorphisms in the UGT1A8, UGT1A9, and UGT2B7 genes, the enzymes producing the phenolic (MPAG) and acyl (AcMPAG) glucuronides of mycophenolic acid (MPA), could contribute to the interindividual variation observed in mycophenolate mofetil (MMF) pharmacokinetics (PKs). This study enrolled 17 healthy volunteers with no polymorphisms(More)
Indocyanine green clearance (Cl-ICG) has been used to assess liver function and hepatic blood flow mainly before and after hepatic surgery. Cl-ICG (invasive method) has been reported to be a good marker of early graft function after liver transplantation (LT). The goal of this study was to determine if the indocyanine green plasma disappearance rate(More)
The human uridine diphospho (UDP)-glucuronosyltransferase (UGT) superfamily comprises enzymes responsible for a major biotransformation phase II pathway: the glucuronidation process. The UGT enzymes are located in the endoplasmic reticulum of almost all tissues, where they catalyze the inactivation of several endogenous and exogenous molecules, including(More)
