A role for local corticosteroid metabolism by 11beta-hydroxysteroid dehydrogenase type 1 (11b-HSD1) has been proposed in bone and adipose tissue physiology. In vivo, 11b-HSD1 predominantly converts inactive cortisone to active cortisol and enzyme activity is critically dependent on substrate concentration. To examine 11b-HSD1 activity in vivo we have analysed the relationship between serum cortisone and markers of bone turnover, BMD and adipose tissue mass in a c...
