Activation of human liver 3alpha-hydroxysteroid dehydrogenase by clofibrate derivatives.
The NADP+-dependent dehydrogenase activity of a predominant isoenzyme of human liver 3alpha-hydroxysteroid dehydrogenase was activated by antihyperlipidemic drugs, such as bezafibrate and clinofibrate, and by clofibric acid and fenofibric acid (active metabolites of clofibrate and fenofibrate, respectively). The optimal pH of the activation by the drugs was about 7.5, and the concentrations giv...
متن کاملGenetic manipulation of 11beta-hydroxysteroid dehydrogenases in mice.
11beta-hydroxysteroid dehydrogenases (HSDs) interconvert active 11-hydroxy glucocorticoids (cortisol, corticosterone) and their inert 11-keto derivatives (cortisone, 11-dehydrocorticosterone). 11beta-HSD type 1 is a predominant reductase that regenerates active glucocorticoids in expressing cells, thus amplifying local glucocorticoid action, whereas 11beta-HSD type 2 catalyzes rapid dehydrogena...
متن کاملDistribution of glucocorticoid and mineralocorticoid receptors and 11beta-hydroxysteroid dehydrogenases in human and rat ocular tissues.
PURPOSE The administration of glucocorticoids as topical or systemic medications may lead to the development of ocular hypertension through the induction of morphologic and biochemical changes in the trabecular meshwork leading to a reduction in the facility of aqueous outflow. Glucocorticoids exert their physiological effects by binding to and activating glucocorticoid and mineralocorticoid re...
