Adrenotrophin is a peptide hormone that is secreted by the pituitary gland and stimulates the release of adrenal hormones. It is also known as adrenocorticotropic hormone (ACTH) and corticotrophin. Some other synonyms for adrenotrophin include adrenocorticotrophic hormone, corticotrophin-releasing hormone, and corticotropin-releasing factor. These hormones are important in regulating the body's stress response, immune function, and metabolism. In diseases like Cushing's syndrome and Addison's disease, the levels of adrenotrophin can be altered, leading to health complications. Medical professionals use various diagnostic techniques to measure adrenotrophin levels and determine appropriate treatment options.
