The Aberrant Expression of the Gastric Inhibitory Polypeptide (GIP) Receptor in Adrenal Hyperplasia: Does Chronic Adrenocorticotropin Exposure Stimulate Up-Regulation of GIP Receptors in Cushing’s Disease?

Abstract

These data are consistent with the hypothesis that chronic ACTH stimulation or constitutive activation of the ACTH signaling pathway may be associated with aberrant GIPR expression, and suggest one mechanism for the pathogenesis of this phenomenon.
