Dr. Gustafsson is interested in understanding the molecular pathways that regulate the life and death of cardiac myocytes. Activation of cell death pathways is a common occurrence in cardiovascular disease and contributes to the development of heart failure. Using genetic and molecular biology approaches, Dr. Gustafsson's research is examining how the E3 ubiquitin ligase Parkin regulates removal of dysfunctional mitochondria in cells; and b) determining the molecular mechanisms by which BCL-2 family proteins regulate mitochondrial function, morphology and turnover in cells.
Another area of interest is to understand the mechanism(s) of late onset cardiotoxicity of anthracyclines. While anthracyclines are among the most effective chemotherapeutic agents commonly used in both children and adults, they are problematic because they are associated with cardiotoxicity. Heart failure may manifest years (>10 yrs) after initial exposure to the anthracyline. Cardiac stem cells provide a mechanism for minor repair and ongoing cell turnover in the heart. She has discovered that anthracyclines impair stem cell function in the young heart, resulting in a heart that is more susceptible to stress. Additional research examines how anthracylines interfere with stem cell function and whether stem cell can be used in cell replacement therapy to prevent cardiotoxicity.
