Current Research

Ischemic heart disease remains as the single largest cause of mortality in western countries. A major challenge in the field of molecular cardiology is developing novel therapeutic approaches to prevent injury and to facilitate recovery of cells that are constantly undergoing physiological stress. My long term research interests are to understand the molecular and cellular mechanism for myocardial repair and regeneration after myocardial infarction, and to develop molecular and cellular therapeutic approaches for preventing myocardial injury, promoting the regeneration following cardiac muscle damage, and treatment for patients with heart diseases. Specifically, the current projects in my laboratory include the use of preconditioned adult stem/progenitor cells for myocardial repair on the therapeutic applications for cardiovascular diseases, as well as understanding the role of muscle specific TRIM family protein, MG53, in healthy and diseased heart. To achieve our goals, we will use multidisciplinary approaches that include biochemistry, molecular biology, cell biology, and genetic analysis through the modulation of mouse models.



Research Interests

1. Enhancing the effectiveness of human cardiac stem cell therapy; 2. The role of MG53 (TRIM72) in cardiac development and regeneration;
