Apelin-13 is a peptide known as the ligand of the G-protein-coupled receptor APJ. [1]. Apelin-13 activated this G protein-coupled receptor with an EC50 value of 0.37 nM [2]. Apelin has been shown to be involved in the regulation of cardiovascular and fluid homeostasis, food intake, cell proliferation, and angiogenesis [1].
Apelin-13 was shown to inhibit insulin secretion stimulated by high glucose concentrations (10 mM) or potentiated by GLP-1 in INS-1 cells [3]. Apelin-13 at 200 nM can enhance H9c2 cell proliferation, which is mediated by the ERK1/2 and Akt signaling pathway [4].
Apelin-13 treatment significantly lowers blood glucose and protects HFD mice from hyperinsulinemia [5]. There are some contradictory reports about the effects of apelin-13/APJ on hypertension. Intraperitoneally administered Apelin-13 reduces blood pressure in hypertensive rats by inhibiting renin-angiotensin system [6]. Chronic infusion of apelin-13 into the paraventricular nucleus induces hypertension through increasing the levels of plasma norepinephrine and arginine vasopressin in normotensive rats [7].
