The 11-beta hydroxysteroid dehydrogenase (11βHSD) isozymes are well-known regulators of glucocorticoid hormone metabolism: 11βHSD2, mostly expressed in the distal nephron, converts cortisol [F] into cortisone [E] in humans or corticosterone into 11-dehydrocorticosterone in rodents (11-dehydro derivatives being inactive compounds), and 11βHSD1, ubiquitously expressed but predominantly in the liver, catalyzes the opposite reaction. Under pathophysiological conditi...
