Inactivation of Tryptophan Oxygenase in Vivo and in Vitro

open access: yesJournal of Biological Chemistry, 1972
Abstract The loss of tryptophan oxygenase from rat livers after induction by hydrocortisone treatment was studied in living rats, isolated perfused livers, liver slices and cell-free preparations of these livers. Measurements of the enzyme by its activity and as an antigen were parallel except for apparently nonspecific inactivations in some ...

N-Nitroso products from the reaction of indoles with Angeli's salt [PDF]

open access: yes, 2006
While nitroxyl (HNO) has been shown to engage in oxidation and hydroxylation reactions, little is known about its nitrosating potential. We therefore sought to investigate the kinetics of formation and identity of the reaction products of the classical ...

Indoxyl Sulfate Affects Glial Function Increasing Oxidative Stress and Neuroinflammation in Chronic Kidney Disease: Interaction between Astrocytes and Microglia

open access: yesFrontiers in Pharmacology, 2017
Indoxyl sulfate (IS) is a protein-bound uremic toxin resulting from the metabolism of dietary tryptophan which accumulates in patients with impaired renal function, such as chronic kidney disease (CKD).

Regulatory Properties of Hepatic Tryptophan Oxygenase

open access: yesJournal of Biological Chemistry, 1972
Abstract The kinetic properties of highly purified hepatic l-tryptophan oxygenase have been studied at different hydrogen ion concentrations in the absence and presence of dl-α-methyltryptophan and 3-hydroxyanthranilic acid. At pH 8.0 plots of velocity versus l-tryptophan concentrations indicate classical hyperbolic Michaelis-Menten kinetics, whereas ...

Genes and pathways for CO2 fixation in the obligate, chemolithoautotrophic acidophile, Acidithiobacillus ferrooxidans, Carbon fixation in A. ferrooxidans

open access: yesBMC Microbiology, 2010
Background Acidithiobacillus ferrooxidans is chemolithoautotrophic γ-proteobacterium that thrives at extremely low pH (pH 1-2). Although a substantial amount of information is available regarding CO2 uptake and fixation in a variety of facultative ...

Initial steps in the induction by glucocorticosteroids of rat liver tryptophan oxygenase and tyrosine aminotransferase

open access: yes, 1978
Approximately 90 min after the application of dexamethasone, an increase in the activity of the liver enzymes tryptophan oxygenase and tyrosine aminotransferase in adrenalectomized male rats could be measured. As early as 30 sec after the injection of an

NMDA receptor activation mediates lipopolysaccharide-induced depressive-like behavior

open access: yesEuropean Journal of Psychotraumatology, 2012
Background : Inflammation associated with cancer and induced by cancer therapy is associated with clinical signs of sickness behavior that can culminate in the development of symptoms of depression. Intraperitoneal administration of lipopolysaccharide to
