POMC and Alzheimer disease: It should be noted that follicle-stimulating hormone (FSH) and adrenocorticotropic hormone (ACTH) are also known to increase StAR expression ([31] and [32], respectively); however, we did not include the receptors for these hormones in this colocalization study as the FSH receptor has not been reported in the brain and ACTH is decreased in AD [33,34].
