Carbon tetrachloride (CCl4) administration to rats produces hepatic cirrhosis and supplementation with S-adenosylmethionine (SAM) can partially prevent CCl4-induced liver injury. These effects are thought to be caused by oxidative stress and the subsequent formation of free radicals, but the mechanism whereby this occurs and the accurate nature of the(More)
BACKGROUND/AIM The aim of this study was to investigate the effects of S-adenosylmethionine on liver peroxidation and liver fibrogenesis in carbon tetrachloride-induced cirrhosis. METHODS Cirrhosis was induced in three groups of six rats by repeated injections of carbon tetrachloride over 9 weeks. One group of animals was treated only with carbon(More)
In various experimental models, S-adenosylmethionine (SAMe) has been shown to reduce liver injury by preventing depletion of glutathione, one of the antioxidant systems that plays a critical role in defence against oxidative stress. On the other hand, alpha-tocopherol may be decreased in liver diseases, and treatment with this vitamin reduces liver injury(More)
Because transcription factors NF-kappaB and activator protein-1 (AP-1) are known to regulate gene expression, we have analyzed the role of acetaldehyde in the activation of NF-kappaB and AP-1 in HepG2 cells. Binding activity and transactivation of NF-kappaB and AP-1 were determined by gel retardation assays and transfection of a luciferase reporter(More)
Carbohydrate-deficient transferrin (CDT) has been proposed as a marker of alcohol abuse. However, its value in patients with associated liver disease is still controversial. The aim of the study was to investigate the usefulness of CDT as a marker of alcohol consumption in patients with liver disease. We measured serum levels of CDT and those of commonly(More)
