This report is a summary of a symposium on the role of S-adenosylmethionine (SAM), betaine, and folate in the treatment of alcoholic liver disease (ALD), which was organized by the National Institute on Alcohol Abuse and Alcoholism in collaboration with the Office of Dietary Supplements and the National Center for Complementary and Alternative Medicine of(More)
Deficiencies in vitamins or other factors (B6, B12, folic acid, betaine) and genetic disorders for the metabolism of the non-protein amino acid-homocysteine (Hcy) lead to hyperhomocysteinemia (HHcy). HHcy is an integral component of several disorders including cardiovascular disease, neurodegeneration, diabetes and alcoholic liver disease. HHcy unleashes(More)
S-Nitrosylation is a reversible post-translational modification on cysteinyl thiols that can modulate the function of redox-sensitive proteins. The S-nitrosylation of mitochondrial proteins has been shown to regulate various mitochondrial activities involved in energy-transducing systems and mitochondrion-driven apoptosis. In isolated rat brain(More)
Our aim was to better understand the mechanism and importance of sustained c-Jun N-terminal kinase (JNK) activation in endoplasmic reticulum (ER) stress and effects of ER stress on mitochondria by determining the role of mitochondrial JNK binding protein, Sab. Tunicamycin or brefeldin A induced a rapid and marked decline in basal mitochondrial respiration(More)
RATIONALE Portopulmonary hypertension (PPHTN) occurs in 6% of liver transplant candidates. The pathogenesis of this complication of portal hypertension is poorly understood. OBJECTIVES To identify genetic risk factors for PPHTN in patients with advanced liver disease. METHODS We performed a multicenter case-control study of patients with portal(More)
Selective injury of the globus palli-dus in children with post-cardiac surgery choreic syndrome. saccadic palsy due to pontine lesions: clinical, physiological and pathological correlations. To the Editor: Hepatotoxicity has been associated with all forms of interferon beta. 1 Autoimmune hepatitis (AIH), another hepatic complication of IFN (beta)-1a(More)
Glutathione plays a key role in the liver in detoxification reactions and in regulating the thiol-disulfide status of the cell. Glutathione synthesis is regulated mainly by the availability of precursor cysteine and the concentration of glutathione itself which feeds back to regulate its own synthesis. Degradation of hepatic glutathione is principally(More)
The FDA guidance for industry in the premarketing clinical evaluation of drug-induced liver injury (DILI) is the most specific regulatory guidance currently available and has been useful in setting standards for the great majority of clinical indications involving subjects with a low risk of liver disorders. However, liver safety assessment faces challenges(More)
