Regulators of G-protein Signalling (RGS) proteins have been shown to limit in vitro signalling of G proteins. In common with end-stage heart failure, we have recently shown that upregulation of the inhibitory G-protein, Gialpha, occurs in acutely failing donor hearts unused for transplantation due to severe myocardial dysfunction. In light of recent data on RGS proteins, we have evaluated mRNA and protein expression of RGS3, RGS4 and Gialpha2 in the myocardium from normal, end-stage failing and acutely failing unused donor hearts.
