Biochem/physiol Actions

(Pyr1)-Apelin-13, the major apelin form in human plasma and heart, corresponds to Apelin-13 with posttranslationally modified pyroglutamyl (pGlu, pE) at the N-terminus instead of glutamine (Gln, Q). (Pyr1)-Apelin-13 exhibits higher APJ agonist potency than Apelin-13 (EC50 = 0.30 vs. 0.37 nM, respectively; acidification induction in human APJ-expresing CHO cell cultures). (Pyr1)-Apelin-13 is reactive toward human, murine, rat, and bovine species, and widely used for studyinhg APJ-mediated cellular and physiological functions both in cultures and in animals in vivo (via intraperitoneal, intravenous, intrathecal injection).

Apelin is emerging as an important hormone regulator of cardiovascular homoeostasis and an important biomarker for heart failure. Apelin concentrations have historically been measured by immunoassays; however, reported apelin concentrations measured in healthy volunteers show a large disparity from a

Apelin is the endogenous ligand for the G protein-coupled receptor APJ and exerts a key role in regulating cardiovascular functions. We report herein a novel series of macrocyclic analogues of apelin-13 in which the N- and C-terminal residues as well

In the search for an endogenous ligand of the orphan G protein-coupled receptor APJ, the presence of the ligand in various tissue extracts was examined by measuring the increase in extracellular acidification rate of the cells expressing the APJ receptor
