Brief Description of Project:
Our laboratory is interested in molecular signaling processes in cardiac hypertrophy and failure. Using molecular, physiological, and electrophysiological approaches, we study mechanisms of structural, functional, and electrical remodeling in heart disease. These studies are based on genetic and surgical models of heart disease in animals, as well as patients with hypertrophic heart disease and cardiomyopathy.
Specific questions we are studying at present include:
Previous Research Activities or Publications with Medical Students:
In several instances, summer students have made substantive contributions to on-going research projects. When this occurs, their efforts are acknowledged with co-authorship on manuscripts. Examples of this include the following:
