Molecular mechanisms of muscle function, human diseases of muscle, vascular smooth muscle and lymphocyte activation
A major focus of the laboratory is the study of mechanisms that regulate muscle contraction. In particular we use a variety of techniques including molecular biology, biophysics, cell biology, imaging (Live5 Zeiss Confocal), and structural biology to gain better understandings of the regulation of calcium release channels on the sarcoplasmic reticulum that control excitation-contraction (EC) coupling in cardiac and skeletal muscle. There are opportunities for graduate students and postdoctoral fellows to head their own projects using any of the various techniques that we employ to examine the regulation of calcium signaling and muscle function in normal and diseased states. In addition the laboratory has developed numerous genetic mouse models (primarily knock-ins and knock-outs) that are available to address specific questions concerning the regulation of key signaling pathways that control muscle contraction - in both cardiac and skeletal systems.
Much of the work in the laboratory is "translational" in that it leads directly to understanding the molecular basis of human diseases including heart failure and sudden cardiac death. In addition, novel therapeutic approaches are being tested including those that fix the "leak" in the RyR2 calcium release channel that causes heart failure and sudden cardiac death.
In addition, there are projects focusing on gaining better understandings of cardiac muscle growth and excitability, T cell and B cell activation, as well as vascular smooth muscle proliferation. The latter project has lead directly to the development of the drug eluting stents that are currently used for patients with coronary artery disease.
