To evaluate the potential roles that both receptors and enzymes play in corticosteroid regulation of intestinal function, we have determined glucocorticoid receptor (GR), mineralocorticoid receptor (MR), and 11β-hydroxysteroid dehydrogenase (11β-HS

Severe low-renin hypertension has few known causes. Apparent mineralocorticoid excess (AME) is a genetic disorder that results in severe juvenile low-renin hypertension, hyporeninemia, hypoaldosteronemia, hypokalemic alkalosis, low birth weight, fail

Recently, we identified a novel putative nuclear receptor in colonic crypt cells distinct from both mineralocorticoid receptor and glucocorticoid receptor, with high affinity for 11-dehydrocorticosterone (11-DHB) (33). In the present study, competiti

Background Apparent mineralocorticoid excess (AME) is a cause of low-renin, low-aldosterone hypertension in which cortisol acts as a mineralocorticoid. The condition reflects an inability to inactivate cortisol to cortisone due to defective activity

The 11β-hydroxysteroid dehydrogenase type II enzyme (11βHSD2) is a potent inactivator of glucocorticoids and is present in high amounts in the placental syncytiotrophoblast and sodium-transporting epithelia. Placental 11βHSD2 is thought to protect

The 11beta-hydroxysteroid dehydrogenase type II enzyme (11betaHSD2) endows specificity on the mineralocorticoid receptor by metabolising glucocorticoids. Sequence comparisons with other microsomal proteins showed the strongly preferred topology of a

The 11 beta-hydroxysteroid dehydrogenase type II enzyme (11 beta HSD2) converts cortisol to cortisone, allowing the non-selective mineralocorticoid receptor to bind aldosterone. When the activity of this enzyme is compromised, as occurs in licorice i

We describe a new member of the 17beta-hydroxysteroid dehydrogenase group of enzymes. Human Pan1b displays greatest activity with 5alpha-androstan-3alpha,17beta-diol (3alpha-Diol) as substrate, suggesting that it may be important in androgen metaboli

When small intestinal epithelial cells are incubated with [3H]corticosterone, nuclear binding is displaced neither by aldosterone nor RU-28362, suggesting that [3H]corticosterone is binding to a site distinct from mineralocorticoid receptor and gluco

Short chain alcohol dehydrogenases have an invariant YXXXK motif at the active site. Database analysis of 116 superfamily members showed that 92% also contain a Serine or Threonine residue at the Y + 1 or Y + 3 positions, a pattern we previously desc
