- Stage-specific changes in myofilament protein phosphorylation following myocardial infarction in miceLori A Walker
University of Colorado Health Sciences Center, Department of Medicine Cardiology, Aurora, CO 80045, USA
J Mol Cell Cardiol 48:1180-6. 2010..These data suggest that temporal changes in myofilament protein phosphorylation contribute both to the initial compensatory hyperdynamic response to myocardial infarction and subsequently to the gradual progression to myocardial failure...
