Background 

Research

Dr. Rovner has training and experience in a number of areas including muscle physiology, carbohydrate metabolism, and molecular biological manipulation of muscle contractile proteins. Dr. Rovner's current research focuses on two broad areas. The first is an assessment of the relationship between structure and function of cardiac and smooth muscle contractile proteins, most notably the motor protein myosin. This involves characterization of both naturally-occurring molecules which differ in the isoform makeup of their component subunits, as well as the recombinant expression of myosins with specific amino acid substitutions or deletions. After purification, these myosin molecules are then assayed in vitro for filament assembly, ATPase activity, and the ability to move actin filaments in a motility assay. A second area is devoted to studying the processes which lead to decreased expression of the proteins involved in Ca2+ cycling in cardiac muscle undergoing pressure-overload hypertrophy or heart failure. This work hopes to identify the pressure-activated factors and second-messenger pathways which regulate the expression of various gene products involved in the release and re-uptake of this critical ion.
