A direct consequence of the Mitochondrial Renaissance which has occurred in the biological sciences over the past 15 years is the recognition that mitochondria do not simply serve as the primary source of ATP in the cell, but they also serve as centralized focal points of cellular signaling, facilitating an assortment of cellular processes from growth and differentiation to apoptosis using a variety of intermediates (see diagram below).

The primary research focus of my laboratory is centered on the role of lipids and reactive oxygen species (ROS) in altering mitochondrial function, and in how the mitochondria uses these and other molecular intermediates to communicate with the rest of the cell, particularly the nucleus, in normal physiological states as well as disease. An increased understanding of these processes, coupled with improvements in mitochondrial-targeted pharmaceutical chemistry, will allow a new era to become realized where mitochondria are a viable therapeutic target in disease management.

We have recently established a strong and dynamic collaboration with cardiac surgeons here at the East Carolina Heart Institute (ECHI), and this has allowed us to obtain human cardiac tissue biopsies from patients at time of surgery. Using a number of techniques to study mitochondrial function at the subcellular (i.e. organelle) and whole cell ‹ level in this tissue, we have recently uncovered a number of interesting mitochondrial abnormalities present in patients with type 2 diabetes (Anderson et al, J Amer Coll Cardiol, Vol. 54 No. 20, 1891-1898 (2009). Current research projects in my lab have both Clinical and Basic science research aspects. Having on-going projects rooted in both of these disciplines allows us to address fundamental questions about cellular physiology yet still keep our attention on the importance of these questions in a clinically relevant context. Research in our lab is supported by industry (GlaxoSmithKline) and federal (NIH) sponsors.

Research interests

  1. Role of n-3 poly-unsaturated fatty acids (PUFAs) in modulating cardiac mitochondrial function in health and disease (Basic and Clinical research components)
  2. Relationship between cardiac glutathione redox chemistry and post-operative atrial fibrillation (Clinical Science)
  3. Impact of cytokines such as TNFα and adiponectin on mitochondrial function in cardiomyocytes (human cardiomyocytes and rodent models)
  4. Role of cardiac mitochondria in mediating cytokine signals from plasma membrane à nucleus (human cardiomyocytes and rodent models)
  5. Molecular intermediates that mediate the cross-talk between mitochondria and nucleus during cellular stress (human cardiomyocytes and rodent models)
