Basic science investigations span an array of inquiries, such as understanding the basic mechanisms underlying cardiac dyssynchrony and resynchronization in the failing heart, and beneficial influences of nitric oxide/cGMP/protein kinase G and cGMP-targeted phosphdiesterase signaling cascades on cardiac maladaptive stress remodeling. Recently, the latter has particularly focused on the role of phosphodiesterase type 5 and its pharmacologic inhibitors (e.g. sildenafi, Viagra®), on myocyte signaling cascades modulated by protein kinase G, and on the nitric oxide synthase dysregulation coupled with oxidant stress.
The lab also conducts clinical research and is presently exploring new treatments for heart failure with a preserved ejection fraction, studying ventricular-arterial interaction and its role in adverse heart-vessel coupling in left heart failure and pulmonary hypertension, and testing new drug, device, and cell therapies for heart disease. A major theme has been with the use ...of advanced non-invasive and invasive catheterization-based methods to assess cardiac mechanics in patients.asive and invasive catheterization-based methods to assess cardiac mechanics in patients.

The Nauder Faraday Lab investigates topics within perioperative genetic and molecular medicine. We explore thrombotic, bleeding and infectious surgical complications. Our goal is to uncover the molecular determinants of outcome in surgical patients, which will enable surgeons to better personalize a patient’s care in the perioperative period. Our team is funded by the National Institutes of Health to research platelet phenotypes, the pharmacogenomics of antiplatelet agents for preventing cardiovascular disease, and the genotypic determinants of aspirin response in high-risk families.
The Pedersen Laboratory is interested in cell energetics and the relationship of cell energetics to molecular medicine and disease. Both mitochondrial and glycolytic processes are being studied at the tissue, cell, and molecular level. Also, the relationship of these processes to cancer and heart disease, the two major causes of death in the U.S., is being studied with the objective of discovering and developing new therapies.
Specific projects in the laboratory that are currently under investigation include: 1) The structure, mechanism, and regulation of the mitochondrial ATP synthase/ATPase complex; 2) The molecular basis of cancer's most common phenotype, i.e., an elevated glucose metabolism; and 3) The regulation of heart function under normal and ischemic conditions as it relates to the mitochondrial ATP synthase/ATPase complex.
Our team consists of chemists, biologists and clinicians who work together in a highly collaborative environment.
