Research Interests

The JAK-STAT axis plays a critical role in cell signaling initiated by various growth factors as related to cell survival and apoptosis. Over the last decade, Dr. Yu-Ting Xuan's work has identified a role of this pathway in protection of heart muscle against ischemic injury. Dr. Xuan's NIH-funded research is focused on understanding the complex signaling pathway involved in the activation of transcriptional factors leading to the upregulation of cardioprotective proteins during myocardial ischemia/reperfusion injury and ischemic preconditioning. Additionally, Dr. Xuan's team is also working on understanding the apoptotic and anti-apoptotic mechanisms of bone-marrow-derived adult stem cells and on improving the survival of these cells after transplantation into the heart. Results from these projects are likely to provide important information that may benefit patients with coronary artery disease who experience heart attacks
