Sustained ELABELA Gene Therapy in High-salt Diet-induced Hypertensive Rats

Background: Elabela (ELA) is a recently identified apelin receptor agonist essential for cardiac development, but its biology and therapeutic potential are unclear. In humans, ELA transcripts are detected in embryonic stem cells, induced pluripotent stem cells, kidney, heart and blood vessels. ELA through the apelin (APJ) receptor promotes angiogenesis in vitro, relaxes murine aortic blood vessels and attenuates high blood pressure in vivo. The APJ receptor when bound to its original ligand, apelin, exerts peripheral vasodilatory and positive inotropic effects, conferring cardioprotection in vivo.
