UDP-glucuronosyltransferases are a family of drug metabolizing enzymes contributing to hepatic drug metabolism and protection against environmental toxins. The aim of this study was to identify polymorphisms at the human UGT1A gene locus and to characterize their function and potential association with hepatocellular carcinoma (HCC). Genomic DNA from the(More)
Autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) are immune-mediated chronic inflammatory diseases of the liver of unknown etiology. Genetic factors appear to be involved in the pathogenesis of both diseases. 1,25-Dihydroxyvitamin D(3) has been implicated as an immunomodulator, which acts through its own receptor (VDR). Polymorphisms of the(More)
BACKGROUND/AIMS No study has compared the liver fibrosis progression rates among chronic liver diseases and the risk factors in order to better organize screening strategies. METHODS A total of 4852 patients were retrospectively studied (chronic hepatitis C (HCV) [n=2313], human immunodeficiency virus (HIV)-HCV co-infection (HIV-HCV [n=180]), hepatitis B(More)
BACKGROUND Liver transplantation is the final therapeutic option for about 10% of patients with autoimmune hepatitis (AIH) who do not respond to medical therapy. The aim of this study was to evaluate the long-term outcome in serologically defined subgroups of AIH after transplantation. METHODS Pre- and post-transplantation data of 28 patients with AIH(More)
BACKGROUND Genetic polymorphisms in the human UDP-glucuronosyltransferase-1A7 (UGT1A7) gene are detected and significantly correlated with sporadic colorectal carcinoma. UGT1A7, which has recently been demonstrated to glucuronidate environmental carcinogens, is now implicated as a cancer risk gene. A silent mutation at codon 11 and missense mutations at(More)
UDP glucuronosyltransferases (UGT) detoxify bilirubin and therapeutic drugs, a process influenced by single nucleotide polymorphisms (SNPs) in their structural genes and promoter elements. UGT1A1*28 is a functional UGT promoter polymorphism associated with Gilbert's disease and severe irinotecan toxicity, which also occurs in the absence of UGT1A1*28. The(More)
BACKGROUND & AIMS Chronic pancreatitis and pancreatic adenocarcinoma are associated with alcohol abuse, consumption of tobacco smoke, and environmental aromatic hydrocarbon exposure. The role of genetic factors is incompletely defined. Uridine 5'-diphosphate glucuronosyltransferases are phase II detoxifying enzymes capable of tobacco-borne toxicant(More)
IMPORTANCE Aside from the multikinase inhibitor sorafenib, there are no effective systemic therapies for the treatment of advanced hepatocellular carcinoma. OBJECTIVE To assess the efficacy of everolimus in patients with advanced hepatocellular carcinoma for whom sorafenib treatment failed. DESIGN, SETTING, AND PARTICIPANTS EVOLVE-1 was a randomized,(More)
BACKGROUND & AIMS The transcription factor nuclear factor-eythroid 2-related factor 2 (Nrf2(-/-)) is essential for protecting cells against xenobiotic and oxidative stress. Increased oxidative stress has been implicated in the pathophysiology of many diseases including ethanol-induced liver disease. Therefore, the role of Nrf2(-/-) in ethanol-induced liver(More)
BACKGROUND & AIMS Hepatocellular carcinoma is associated with risk factors including hepatitis C, hepatitis B, cirrhosis, genetic liver diseases, and environmental carcinogens. Uridine 5'-diphosphate-glucuronosyltransferases are a superfamily of detoxifying enzymes capable of tobacco-borne carcinogen detoxification and cellular protection. This study(More)
