Hepatic steatosis is a consequence of distorted lipid storage and plays vital role in the pathogenesis nonalcoholic fatty liver disease (NAFLD). This study aimed to explore COP9 signalosome (CSN) development hepatic its interplay with deubiquitylating enzyme (DUB) cylindromatosis (CYLD). CSN occurs as CSNCSN7A CSNCSN7B variants regulating ubiquitin proteasome system. It deneddylating complex as...

A murine renal microsomal enzyme responsible for the mutagenic activation of 3-methoxy-4-aminoazobenzene (3-MeO-AAB) was characterized by its catalytic activity for the mutagenic and metabolic conversion of 3-MeO-AAB. Incubation of 3-MeO-AAB with a renal or hepatic microsome fraction from male BALB/c mice in the presence of NADPH and NADH yielded N-hydroxy and 4'-hydroxy metabolites of 3-MeO-AA...

Two patients abruptly developed congestive heart failure and elevation in serum transaminase levels when given disopyramide phosphate; enzyme abnormalities and hemodynamic status corrected upon withdrawal of the drug. Both patients had underlying ischemic cardiomyopathy. Myocardial infarction, pulmonary embolism, and viral hepatitis were ruled out in both patients. One patient had a liver biops...

We investigated the mechanism of nitric oxide (NO) action on hepatic methionine adenosyltransferase (MAT) activity using S-nitrosoglutathione (GSNO) as NO donor. Hepatic MAT plays an essential role in the metabolism of methionine, converting this amino acid into S-adenosylmethionine. Hepatic MAT exists in two oligomeric states: as a tetramer (MAT I) and as a dimer (MAT III) of the same subunit....

We compared the capability of rapid enzyme immunoassay (EIA) to detect antiamoebic antibodies during hepatic amoebiasis with those of indirect hemagglutination and latex agglutination. EIA is simple to perform and rapid (20 min) and does not require any special equipment (optical reading is sufficient). EIA of 143 sera (including 43 from patients with proven hepatic amoebic abscess, 33 from pat...

The role of reactive oxygen species in liver fibrogenesis is not yet clarified [11]. Huang et al. [13] showed a progressive increase in plasma malondialdehyde, hepatic 8-hydroxy-2’-deoxyguanosine, hepatic mitochondrial respiratory functions and procollagen I and III or transforming growth factor1 mRNA expression in rats rendered cirrhotic by bile duct ligation. There is also a progressive impai...
