Analysis of in vitro and in vivo metabolism of zidovudine and gemfibrozil in trans‐chromosomic mouse line expressing human UGT2 enzymes

open access: yesPharmacology Research & Perspectives, 2022
UDP‐glucuronosyltransferases (UGTs) catalyze the conjugation of various substrates with sugars. Since the UGT2 family forms a large cluster spanning 1.5 Mb, transgenic mouse lines carrying the entire human UGT2 family have not been constructed because of

Assay for the terminal enzyme of the stearoyl coenzyme A desaturase system using chick embryo liver microsomes

open access: yesJournal of Lipid Research, 1977
The NADH-dependent stearoyl CoA desaturase of hepatic microsomes (EC 1.14.99.5) is an enzyme system consisting of cytochrome b5 reductase (EC 1.6.2.2), cytochrome b5, and the terminal desaturase. We have developed a simple method for routine assay of the

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.) [PDF]

open access: yes, 2013
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the ...

Biosynthesis of presqualene pyrophosphate by liver microsomes

open access: yesJournal of Lipid Research, 1970
Microsomes from rat liver have been shown to synthesize a squalene precursor from farnesyl pyrophosphate. This intermediate is identical with presqualene pyrophosphate, a 30-carbon cyclopropane containing pyrophosphate ester that had previously been ...

Effect of 3'-methyl-N,N-dimethyl-4-aminoazobenzene in the presence or absence of liver microsomes on the liver cells having low tumor-producing capacity in culture. [PDF]

open access: yes, 1983
A cell strain having low tumor-producing capacity was exposed in culture to 3'-methyl-N,N-dimethyl-4-aminoazobenzene (3'-Me-DAB) in the presence or absence of liver microsomes, and whether or not the cells will progress to those having high tumor ...

Activation of HMG-CoA reductase by microsomal phosphatase

open access: yesJournal of Lipid Research, 1983
HMG-CoA reductase activity can be modulated by a reversible phosphorylation-dephosphorylation with the phosphorylated form of the enzyme being inactive and the dephosphorylated form, active. Phosphatases from diverse sources, including cytosol, have been

Sidedness of ceramide-phosphoethanolamine synthesis on rat liver and brain microsomal membranes.

open access: yesJournal of Lipid Research, 1987
Phosphatidylethanolamine:ceramide-ethanolamine-phosphotransferase catalyzes the synthesis of ceramide-phosphoethanolamine, a sphingomyelin analogue. Its localization was studied in rat liver and brain microsomes.

Молодь і політика: соціологічні парадокси та українські реалії [PDF]

open access: yes, 1980
The exchange of phosphatidylcholine between intact human or rat erythrocytes and rat liver microsomes was greatly stimulated by phosphatidylcholine-specific exchange proteins from rat liver and beef liver.

Involvement of cytochrome P450 2E1 in the (ω–1)-hydroxylation of oleic acid in human and rat liver microsomes

open access: yesJournal of Lipid Research, 1998
In vitro techniques have been used to investigate the nature of microsomal cytochrome P450 involved in the metabolism of oleic acid, a physiological monounsaturated fatty acid. Like lauric acid, which is cur rently used as a model substrate of fatty acid

The role of human cytochrome P450 2E1 in liver inflammation and fibrosis. [PDF]

open access: yes, 2017
Cytochrome P450 2E1 (CYP2E1) plays an important role in alcohol and toxin metabolism by catalyzing the conversion of substrates into more polar metabolites and producing reactive oxygen species.
