The primary interest of my research has been focusing on the pathogenesis of hypertension in renal salt-reabsorption and the systemic vasculature. The long-term goal of our laboratory is to understand the mechanism of the development of hypertension and to translate our basic scientific discovery to clinics to contribute to a final cure for hypertension. To accomplish this goal, we have conducted multiple screenings to identify potential pathogenic targets in hypertension. Extending from our initial screen, we are performing laboratory experiments using both pharmacological and genetic approaches to determine the role of the identified molecules in the development of hypertension. Our most recent project is investigating the role and molecular mechanisms of immune cells in stimulating sodium retention in kidney, which contributes to the pathogenesis of salt-sensitive hypertension. In addition, we have acquired techniques and research experience involved in most areas of physiology, biology, molecular genetics, epigenetics, histology and vascular biology that are needed to pursue our goal of translational medicine. I am collaborating with Phil Palade, Ph.D. and Yunmeng Liu, Ph.D. on this research.
