Metabolism and Cytotoxic Mechanisms of Nitroglycerin in Isolated Rat Hepatocytes
It has been proposed that organic nitrates such as glyceryl trinitrate (GTN), used in the treatment of cardiovascular diseases, act by producing nitric oxide (NO). However, the biochemical pathway for NO formation from GTN is not well understood. In the present study, we showed that nitrate formation from GTN, by isolated rat hepatocytes, was inhibited about 50% when cellular glutathione w...

متن کاملThreonine metabolism in isolated rat hepatocytes.
The removal of the 1-carbon of threonine can occur via threonine dehydrogenase or threonine aldolase, this carbon ending up in glycine to be liberated by the mitochondrial glycine cleavage system and producing CO(2). Alternatively, in the threonine dehydratase pathway, the 1-carbon ends up in alpha-ketobutyrate, which is oxidized in the mitochondria to CO(2). Rat hepatocytes, incubated in Krebs...
متن کاملXenobiotic metabolism by cultured primary porcine hepatocytes.
Considering the large yield of viable cells comparable to human liver, primary porcine hepatocytes offer a valuable resource for constructing a bioartificial liver device. In this study, the ability of cultured primary porcine hepatocytes to detoxify xenobiotics has been examined using various known substrates of cytochrome P450 isoenzymes and UDP-glucuronosyltransferases. Present investigation...
متن کاملKinetics of benzylpenicillin metabolism in isolated rat hepatocytes.
The metabolism of benzylpenicillin (PCG) in isolated rat hepatocytes was investigated. The evidence of metabolizing activity for PCG in hepatic cells was obtained as follows; the disappearance rate of PCG from the incubation medium followed Michaelis-Menten kinetics and was dependent on the cellular protein concentration, while PCG did not disappear when it was incubated with cells denaturated ...
