Research in my laboratory is to understand pathophysiological mechanisms of heart failure and molecular regulation of fetal heart development. We utilize a wide range of approaches ranging from cellular, molecular biology to in vivo physiology and pharmacology. Current research is focused on the role of nitric oxide in fetal heart development and heart failure post myocardial infarction. We have recently demonstrated that nitric oxide is important for fetal heart development. To further understand how nitric oxide contributes to fetal heart development, we are studying the effects of nitric oxide on proliferation of fetal and neonatal cardiomyocytes. Erythropoietin, a glycoprotein essential for red blood cell production, has cardioprotective effects. Ongoing studies are investigating the role of nitric oxide in the cardioprotective effects of erythropoietin following myocardial infarction. Bone marrow stem cells have been shown to migrate to the ischemic heart and participate in cardiac repair post myocardial infarction. We are investigating factors regulating bone marrow stem cell migration to ischemic heart and the ability of the stem cells to repair the infarcted heart. Another area of our research is to study the signal transduction mechanisms in cardiomyocytes in sepsis. Sepsis causes multi-organ dysfunction including the heart. Cytokine production such as tumor necrosis factor (TNF)-alpha contributes significantly to the development of cardiac dysfunction during sepsis. Current studies are focused on signal transduction pathways by which TNF-alpha is produced in cardiomyocytes and how they contribute to cardiac dysfunction during sepsis. Genetically altered mice are employed to identify the contribution of a specific gene in the regulation of cardiovascular function in myocardial infarction, heart failure and sepsis. Studies are currently funded by Canadian Institutes of Health Research and the Heart & Stroke Foundation of Canada.
