Indoleamine 2,3-dioxygenase 1 (IDO1) metabolizes L-tryptophan to kynurenines (KYN), inducing T-cell suppression either directly or by altering antigen-presenting-cell function. Cyclooxygenase (COX)-2, the rate-limiting enzyme in the synthesis of prostaglandins, is over-expressed by several tumours. We aimed at determining whether COX-2 inhibitors down-regulate the IFN--induced expression of ID...
Both ornithine decarboxylase inhibition to deplete polyamines and cyclooxygenase inhibition diminish the migration response to injury of human airway epithelial cells in tissue culture monolayers by approximately 75%. Restoration of normal migration responses is achieved in the polyamine depleted system either by exogenous reconstitution of polyamines or the addition of prostaglandin E(2) (PGE(...
The prostaglandins are lipid mediators, discovered in the 1930s by von Euler in Sweden and Goldblatt in the United Kingdom. They are made by the bifunctional enzyme, cyclooxygenase, which has both cyclooxygenase and peroxidase activities in the same molecule. Prostaglandins are involved in physiological functions such as protection of the stomach mucosa, aggregation of platelets and regulation ...
liquiritigenin is a chiral flavonoid present in plant based food, nutraceuticals, and traditional medicines. it is also an important ingredient present in licorice. the purpose of this study is to explore the pharmacological activity of racemic liquiritigenin utilizing several in vitro assays with relevant roles in colon cancer and diabetes. where possible, the pure enantiomers were tested to i...
