11beta-hydroxysteroid dehydrogenase type 1 regulates glucocorticoid-induced insulin resistance in skeletal muscle.Morgan, Stuart A; Sherlock, Mark; Gathercole, Laura L; Lavery, Gareth G; Lenaghan, Carol; Bujalska, Iwona J; Laber, David; Yu, Alice; Convey, Gemma; Mayers, Rachel; et al. (Diabetes, 2009-11)Glucocorticoid excess is characterized by increased adiposity, skeletal myopathy, and insulin resistance, but the precise molecular mechanisms are unknown. Within skeletal muscle, 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) converts cortisone (11-dehydrocorticosterone in rodents) to active cortisol (corticosterone in rodents). We aimed to determine the mechanisms underpinning glucocorticoid-induced insulin resistance in skeletal muscle and indentify how 11beta-HSD1 inhibitors improve insulin sensitivity.
