Maejima Y, Yokota S, Shimizu M, Horita S, Kobayashi D, Hazama A, Shimomura K (2021) The deletion of glucagon-like peptide-1 receptors expressing neurons in the dorsomedial hypothalamic nucleus disrupts the diurnal feeding pattern and induces hyperphagia and obesity. Nutr Metab (Lond) 18(1):58. doi: 10.1186/s12986-021-00582-z
Summary: Feeding rhythm disruption contributes to the development of obesity. GLP-1 receptors (GLP-1R) are expressed in the dorsomedial hypothalamic nucleus (DMH) which are known to be associated with thermogenesis and circadian rhythm development. These findings suggest that GLP-1R expressing neurons in the DMH may mediate feeding termination.
Dose: Exenatide-SAP targets GLP-1R expressing cells. Injections of 0.1 μg/0.5 μl Ex4-SAP or 0.1 μg/0.5 μl Blank-SAP (control) were administered into the DMH.
