Possible Involvement of Anorexigenic Protein, Nesfatin/Nucleobindin-2 (NUCB2) in Blood Pressure Regulation by Regulating Water Reabsorption in Renal Collecting Duct
Author(s): Hiroyuki Shimizu and Aya OsakiHiroyuki Shimizu and Aya Osaki
Nesfatin/nucleobindin-2 (NUCB2), a precursor protein of anorexigenic protein, nesfatin-1, is ubiquitously expressed in the body. The finding that peripheral administration of nesfatin-1 increases blood pressure indicates a possible involvement of nesfatin-1 in the regulation of blood pressure. The present studies were undertaken to investigate a possible involvement of nesfatin/NUCB2 in the regulation of blood pressure. The immunoreactivity against nesfatin/NUCB2 was selectively found in vascular endothelial cells of aorta, pulmonary artery and renal artery, cardiac muscle and skeletal striated muscle cells, but not in vascular smooth muscle cells at all. Furthermore, the immunoreactivity against nesfatin/NUCB2 was selectively found in renal collecting duct cells, which contain aquaporin (AQP)-2 and/or epithelial sodium channel (ENaC). In medullary collecting ducts, cells expressing n.. Read More»
