Hepatic A-ring reduction of glucocorticoids is enhanced in obesity, perhaps contributing to compensatory activation of the hypothalamic-pituitary-adrenal axis and adrenal androgen excess. One pathway activated is the formation of tetrahydro metabolites by two sequential steps catalysed by 5beta-reductase (5bR) followed by 3alpha-hydroxysteroid dehydrogenases (3HSD). However, regulation of these enzymes is understood poorly. 5bR and 3HSD are also involved in the conversion of c...
