Abstract
BACKGROUND: Human relaxin-2 is a peptide hormone capable of pleiotropic effects in several organ systems. Its recombinant formulation (serelaxin) has been demonstrated to reduce infarct size and prevent excessive scar formation in animal models of cardiac ischemia-reperfusion injury. B7-33, a synthetically designed peptide analogous to B-chain of relaxin-2, invokes signaling at relaxin family peptide receptor 1 (cognate receptor for relaxin-2) by preferentially phosphorylating the mitogen-activated protein kinase extracellular signal-regulated kinase 1/2. We sought to investigate the effects of B7-33 treatment post ischemia-reperfusion injury in mice. METHODS AND RESULTS: Adult male CD1 mice..
