Gastrointestinal hormone upon their chemical structure. Ghrelin is a peptide hormone released from the stomach and liver and is often referred to as the "hunger hormone" since high levels of it are found in individuals that are fasting. Ghrelin agonistic treatments can be used to treat illnesses such as anorexia and loss of appetites in cancer patients. Ghrelin treatments for obesity are still under intense scrutiny and no conclusive evidence has been reached. This hormone stimulates growth hormone release. Amylin controls glucose homeostasis and gastric motility Glucose-dependent insulinotropic polypeptide possesses an acute influence on food intake through its effects on adipocytes Oxyntomodulin
Corticotropin-releasing hormone receptor Corticotropin-releasing hormone receptor Corticotropin-releasing hormone receptors (CRHRs), also known as corticotropin-releasing factor receptors (CRFRs) are a G protein-coupled receptor family that binds corticotropin-releasing hormone (CRH). There are two receptors in the family, designated as type 1 and 2, each encoded by a separate gene ( and respectively). CRHRs are important mediators in the stress response. Cells in the anterior lobe of the pituitary gland known as corticotropes express the receptors and will secrete adrenocorticotropic hormone (ACTH) when stimulated. This binding of corticotropin releasing-hormone (CRH) activates the hypothalamic-pituitary-adrenal (HPA) axis, one of the two parts of the fight-or-flight response to stress.
