Ghrelin, cannabinoids and glucocorticoids have all orexigenic and widespread metabolic effects. AMPK is a major controller of many metabolic processes. We have studied the effects of ghrelin and glucocorticoids and their interaction with endocannabinoids using cannabinoid-receptor-1 (CB1) knock-out mice and CB1 antagonist-treated mice, and using tissue samples from patients with Cushing’s syndrome and from a rodent model of Cushing’s syndrome. AMPK activity and downs...

Background: Excess glucocorticoids result in Cushing’s syndrome (CS) which is characterised by increased food intake, central obesity, dyslipidaemia and insulin resistance, leading to the metabolic syndrome. AMPK is a regulator of energy homeostasis and plays an important role in the regulation of appetite, glucose uptake, lipogenesis and gluconeogenesis. We hypothesised that the effects of corticosteroids on metabolism would be mediated by changes in AMPK activity in a t...
