Title: gamma. sub 2 -MSH immunoreactivity in the human heart

Abstract

In patients undergoing aorto-coronary by-pass surgery, we found a 26% arterial-venous difference of immunoreactive {gamma}{sub 2}-melanocytostimulating hormone (MSH), a proopiomelanocortin (POMC) derived peptide known to possess profound hemodynamic effects. These results prompted an investigation of the presence of {gamma}{sub 2}-MSH in the human heart. Using a two-step extraction procedure, regions of human hearts were examined by sensitive and specific radioimmunoassays to determine their {gamma}{sub 2}-MSH content. Mean ({plus minus} SEM) concentrations of 0.14 {plus minus} 0.023 pmol/g and 0.12 {plus minus} 0.017 were found in right atrium and right ventricle, respectively. High performance liquid chromatography indicated that 80-90 % of the total immunoreactivity eluted in a single sharp peak in a position identical to that of synthetic {gamma}{sub 2}-MSH.
