However, the findings do not exclude the possible involvement of other anorexic substances such as glucagon-like peptide-1 (GLP-1), α-melanocyte-stimulating hormone (α-MSH) derived from proopiomelanocortin (POMC), cocaine- and amphetamine-regulated transcript (CART), corticotophin-releasing hormone (CRH) and nesfatin in CCK-induced anorexia because CCK administration has been shown to activate neurones containing these peptides 43,44–46. This evidence concerns the gene CCK and Anorexia.
