Inadequate calorie intake or starvation has been suggested as a cause of neonatal jaundice, which can further cause permanent brain damage, kernicterus. This study experimentally investigated whether additional glucose treatments induce the bilirubin-metabolizing enzyme--UDP-glucuronosyltransferase (UGT) 1A1--to prevent the onset of neonatal hyperbilirubinemia. Neonatal humanized UGT1 (hUGT1) m...
Uridine diphosphate glucuronosyltransferase 1A (UGT1A) is a major phase II drug-metabolism enzyme superfamily involved in the glucuronidation of endobiotics and xenobiotics in humans. Many polymorphisms in UGT1A genes are reported to inhibit or decrease UGT1A activity. In this study, two UGT1A1 allozymes, UGT1A1 wild-type and a splice mutant, as well as UGT1A9 wild-type and its three UGT1A9 all...
Congenital hereditary non-conjugate hyperbilirubinemias include Gilbert’s syndrome, Crigler-Najjar type 1 and 2 syndromes (or Arias’ disease). They are caused by a deficiency of the enzyme - bilirubinuridine-5’-diphosphate glucuronosyltransferase (UGT1A1), involved in glucuronization bilirubin. The is due to mutations UGT1A1 gene, which provides activity. Complete or almost complete loss (Crigl...
Common, functional, germline genetic polymorphisms have been associated with clinical cancer outcomes. Little attention has been paid to the potential phenotypic consequences of germline genetic variation on downstream genes. We determined the germline status of 16 well-characterized functional polymorphisms in 126 children with newly diagnosed acute lymphoblastic leukemia (ALL). We assessed wh...
Aim: To investigate the association between UDP-glucuronosyltransferase 1A1 (UGT1A1) genotypes and severe toxicity in Taiwanese patients with metastatic colorectal cancer (mCRC) receiving irinotecan chemotherapy. Methods: We genotyped the UGT1A1 gene by direct sequencing. All the patients were evaluated to see whether the variant UGT1A1 genotype would correlate to severe toxicity of irinotecan ...
Chrysin, a dietary flavonoid, has been shown to markedly induce UGT1A1 expression and activity in HepG2 and Caco-2 cell lines; thus, it has been suggested to have clinical utility in the treatment of UGT1A1-mediated deficiencies, such as unconjugated hyperbilirubinemia or the prevention of 7-ethyl-10-hydroxycamptothecin (SN-38) toxicity. However, little is known about its induction potential in...
BACKGROUND Dolutegravir (DTG) is metabolized mainly by uridine diphosphate (UDP)-glucuronosyltransferase 1A1 (UGT1A1), and partly by cytochrome P450 3A (CYP3A). Therefore, we focused on UGT1A1 gene polymorphisms (*6 and *28) in Japanese individuals infected with human immunodeficiency virus (HIV)-1 to examine the relationship between their plasma trough concentration of DTG and gene polymorphis...
We read with interest the paper from Hoskins et al. (1) on the meta-analysis of the studies that assessed the association of irinotecan dose with the risk of irinotecan-related toxic effects for patients with the UGT1A1*28/*28 genotype. They indicated that the risk of hematologic toxicity was strongly associated with UGT1A1*28 genotype at higher irinotecan doses (>150 mg/m 2), not at lower dose...
