Human UDP‐glucuronosyltransferase (UGT)1A3 enzyme conjugates chenodeoxycholic acid in the liver

Jocelyn Trottier, Mélanie Verreault, Susan Grepper, Didier Monté, Julie Bélanger, Jenny Kaeding, Patrick Caron, Ted T. Inaba, Olivier Barbier – 20 October 2006 – Chenodeoxycholic acid (CDCA) is a liver‐formed detergent and plays an important role in the control of cholesterol homeostasis. During cholestasis, toxic bile acids (BA) accumulate in hepatocytes causing damage and consequent impairment of their function. Glucuronidation, a conjugation reaction catalyzed by UDP‐glucuronosyltransferase (UGT) enzymes, is considered an important metabolic pathway for hepatic BA.

The half‐life of hepatitis B virions

John M. Murray, Robert H. Purcell, Stefan F. Wieland – 20 October 2006 – The virion half‐life of hepatitis B virus (HBV) is currently estimated at approximately 1 day. This estimate has been obtained from drug perturbation experiments with reverse transcriptase inhibitors. However, the analyses of those experiments have not considered the export of virions produced from preformed mature DNA‐containing HBV capsids in infected cells.
