“…GALP is expressed in the brain, primarily in the hypothalamic arcuate nucleus (ARC), where it is regulated by various metabolic signals, including leptin, insulin, and metabolic fuels (Fraley et al, 2003a(Fraley et al, , 2004Juréus et al, 2000Juréus et al, , 2001Kumano et al, 2003). Centrally administered GALP has marked effects on feeding and body weight in the rat and mouse (Gundlach, 2002;Krasnow et al, 2003;Lawrence et al, 2002;Matsumoto et al, 2002;Seth et al, 2002Seth et al, , 2003a, and it activates the sympathetic nervous system in the mouse (Hansen et al, 2003). In addition, GALP has a direct stimulatory action on gonadotropinreleasing hormone (GnRH) mediated luteinizing hormone (LH) secretion (Cunningham et al, 2002a,b;Gundlach, 2002;Krasnow et al, 2003;Matsumoto et al, 2001;Shen et al, 2002).…”
