Role of skeletal muscle glucocorticoid receptor in systemic energy homeostasis.

Glucocorticoids (GCs) affect nearly every organ and tissue in the body, regulating diverse physiologic processes including energy homeostasis. The metabolic mission of GCs is to supply enough glucose into the circulation to fuel the brain and ensure survival of the organism under conditions of acute stress or starvation. Recent studies have revealed that GCs, via orchestration between multiple organs, physiologically elicit fine tuning of systemic energy metabolism.
