As indicated above, ACTH is a cleavage product of the pro-hormone, proopiomelanocortin (POMC), which also produces other hormones including α-MSH that stimulates the production of melanin . A family of related receptors mediates the actions of these hormones, the MCR, or melanocortin receptor family. These are mainly not associated with the pituitary - adrenal axis. MC2R is the ACTH receptor . While it has a crucial function in regulating the adrenal, it is also expressed elsewhere in the body, specifically in the osteoblast , which is responsible for making new bone, a continual and highly regulated process in the bodies of air-breathing vertebrates. [10] The functional expression of MC2R on the osteoblast was discovered by Isales et alia in 2005. [11] Since that time, it has been demonstrated that the response of bone forming cells to ACTH includes production of VEGF , as it does in the adrenal. This response might be important in maintaining osteoblast survival under some conditions. [12] If this is physiologically important, it probably functions in conditions with short-period or intermittent ACTH signaling, since with continual exposure of osteoblasts to ACTH, the effect was lost in a few hours.

Several important peptide hormones are secreted from the pituitary gland. The anterior pituitary secretes three hormones: prolactin , which acts on the mammary gland ; adrenocorticotropic hormone (ACTH), which acts on the adrenal cortex to regulate the secretion of glucocorticoids ; and growth hormone , which acts on bone , muscle , and the liver . The posterior pituitary gland secretes antidiuretic hormone , also called vasopressin, and oxytocin . Peptide hormones are produced by many different organs and tissues, however, including the heart ( atrial-natriuretic peptide (ANP) or atrial natriuretic factor (ANF)) and pancreas ( glucagon , insulin and somatostatin ), the gastrointestinal tract ( cholecystokinin , gastrin ), and adipose tissue stores ( leptin ).

Corticosteroids can produce reversible hypothalamic- pituitary adrenal (HPA) axis suppression with the potential for corticosteroid insufficiency after withdrawal of treatment. Adrenocortical insufficiency may result from too rapid withdrawal of corticosteroids and may be minimized by gradual reduction of dosage. This type of relative insufficiency may persist for up to 12 months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted. If the patient is receiving steroids already, dosage may have to be increased.
