Reactive oxygen species (ROS) are known for their participation in various physiological and pathological processes in organisms, including ageing or degeneration. Kynurenine pathway metabolites, such as kynurenic (KYNA) or xanthurenic (XA) acid, can affect neurodegenerative diseases due to their
Thirteen women with chemical diabetes diagnosed in late pregnancy were found to excrete excessive amounts of urinary xanthurenic acid after a tryptophan load, indicative of a relative pyridoxine (vitamin B6) deficiency. Treatment with 100 mg pyridoxine daily for 14 to 23 days restored the urinary
This study describes the functional characterization of a specific mosquito transaminase responsible for catalyzing the transamination of 3-hydroxykynurenine (3-HK) to xanthurenic acid (XA). The enzyme was purified from Aedes aegypti larvae by ammonium sulfate fractionation, heat treatment, and
Oral glucose tolerance, urinary xanthurenic acid excretion, and plasma pyridoxal phosphate concentrations were determined in nine women taking oral contraceptives and in four controls. The tests were repeated after 4 weeks ingestion of a vitamin B6-deficient diet, and again after pyridoxine
BACKGROUND
The physiological processes in the cell are regulated by reversible, electrostatic protein-protein interactions. Apoptosis is such a regulated process, which is critically important in tissue homeostasis and development and leads to complete disintegration of the cell. Pathological
Gestational diabetes mellitus (GDM) is a form of diabetes that is first recognised during pregnancy, with no evidence of pre-existing type 1 or type 2 diabetes. The prevalence of GDM has been rising steadily over the past few decades, coinciding with the ongoing epidemic of obesity and type 2
