research overview

  • One of the major areas of interest in my laboratory over the past 30 years has been understanding the mechanisms whereby the mammalian heart and skeletal system adapts to a wide variety of stimuli and how biologic sex modifies these adaptations. We have shown that male and female hearts and cardiac myocytes have fundamental differences in their function, signaling and molecular biology. My lab has trained many individuals in these areas and many of them occupy prominent leadership positions in cardiovascular academic institutions. I have a strong commitment to training scientists, physicians and physician scientists and participate in many activities that promote career development. 500 mutations in the 10-member striated muscle myosin gene family cause a variety of cardiac and skeletal muscle myopathies. We have invested a great deal of effort into understanding how these mutations affect myosin function using biochemical, cell and mouse genetic approaches. We have intriguing data about an unorthodox myosin, MYH7b that is not expressed in specialized striated muscles, but also in the brain and inner ear. Mutations in MYH7b cause hereditary hearing loss but by unknown mechanisms. We have also recently discovered, through single molecule imaging that myosin molecules travel in and out of sarcomeres very frequently and we are studying the significance of this shuttling and how myosin mutations affect this process.
