Responses to corticotrophin-releasing hormone and dexamethasone in a large series of human adrenocorticotrophic hormone-secreting pituitary adenomas in vitro reveal manifold corticotroph tumoural phenotypes.

Abstract excerpt

Patients with Cushing's disease are known to present a variable secretory response to stimulatory and inhibitory challenges. Evaluation of the secretory behaviour of pituitary adrenocorticotrophic hormone (ACTH)-secreting adenomas in vitro aids in the comprehension of its behaviour in vivo; however, given the small size of these tumours and the consequent paucity of material available to in vitro studies, a...
