- 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...

Division of Cardiology, Department of Medicine, University of Colorado Denver, Aurora, CO 80045, USA
Am J Physiol Heart Circ Physiol 304:H1644-50. 2013..Defining these changes in progressive heart disease may provide important diagnostic and treatment information...
- Tissue procurement strategies affect the protein biochemistry of human heart samplesLori A Walker
Department of Medicine, Division of Cardiology, University of Colorado Denver, B139, 12700 E 19th Ave, Aurora, CO 80045, USA
