The immunocytochemical localization of gamma-glutamyltransferase [(5-glutamyl)-peptide:amino-acid 5-glutamyltransferase, EC 2.3.2.2; gamma-GluTase] was demonstrated in hyperplastic liver induced by the carcinogen 2-acetylaminofluorene (2-AAF). The method used a specific antiserum and protein A-horseradish peroxidase and permitted visualization of antigenic sites at both the light and electron m...

A slow reacting substance produced by rat basophilic leukemia cells, treated with ionophore A23187, was characterized by spectroscopic methods, enzymatic conversions, and chemical degradations as 5-hydroxy-6-S-cysteinylglycyl 7,9,11,14-eicosatetraenoic acid (leukotriene D). gamma-Glutamyltranspeptidase [gamma-glutamyltransferase; (5-glutamyl)-peptide: amino-acid 5-glutamyltransferase, EC 2.3.2....

conclusions smokers with a higher bp and/or serum ggt may be at a higher risk of developing ckd. the associations of bp and serum ggt with ckd in smokers are not entirely mediated by increased insulin resistance or chronic inflammation caused by smoking. patients and methods renal functions and cvd risk factors were assessed in middle-aged male workers. the patients were comprised of 336 nonsmo...

Clinical use of diclofenac is associated with a small but significant incidence of hepatotoxicity. It has been reported that in vivo diclofenac treatment results in decreased activity of the extracellular canalicular membrane protein dipeptidylpeptidase IV in rats as a consequence of protein adduct formation by its electrophilic metabolite diclofenac acyl glucuronide. The present study has inve...
