11β-HSD1KO mice are protected from glucocorticoid dependent age-associated muscle atrophy

Glucocorticoids (GCs) are prescribed for their anti-inflammatory and immunosuppressive properties. However, they have significant side-effects including a decline in muscle mass and function which has similarities to age related sacropaenia. Within skeletal muscle 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts 11-dehydrocorticosterone (11DHC) to active corticosterone (CORT) amplifying local GC action. We hypothesise that 11β-HSD1 mediated intramyoce...

Age-dependent increase in the expression/activity of 11β-HSD1 in key metabolic tissues may underpin the ageing phenotype notably sarcopenia

Morgan Stuart , Sherlock Mark , Lavery Gareth , Hassan-Smith Zaki , Abrahams Lianne , Stewart Paul

The pathophysiological effects of glucocorticoid (GC) excess (Cushing’s syndrome) are similar to the aging phenotype. As such, we hypothesise that age-related changed in body composition (central obesity, reduced bone density, reduced muscle mass and skin thinning), and resultant chronic disease (type 2 diabetes, osteoporosis, sarcopenia and heart disease) may be caused by increased GC exposure with age. However, circulating GC’s show little change with advancing age...

11β-HSD1 knockout mice are protected from the adverse metabolic effects of exogenous glucocorticoid excess

Glucocorticoids (GC), such as prednisolone, are widely prescribed for their anti-inflammatory and immunosuppressive properties. However, they have significant side-effects including insulin resistance and hepatic steatosis. 11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts 11-dehydrocorticosterone (11DHC) to active corticosterone (CORT) and thus amplifies local GC action. We hypothesise that enhanced local GC regeneration of exogenously administered GCs by ...
