- Renal and cardiac physiology of endogenous cardiotonic steroids
A molecular biologist/pharmacologist, Dr. Xie has focused his research for nearly 30 years on an enzyme commonly referred to as the “sodium-potassium pump” because it controls the levels of potassium and sodium entering and exiting cells. This pumping process is vital to transporting essential nutrients like glucose and amino acids into cells and maintaining the electrical charge within cells, which is particularly important in controlling normal functions in nerves and muscles, as well as in the kidney and heart.
Dr. Xie’s research shows that in addition to its critical pumping function, which was discovered by scientists in the 1950s, this “pump” plays a second, distinct role by directing a variety of cellular processes in the heart, kidneys and other tissues. Through their studies to learn more about the molecular mechanisms by which this cellular signaling occurs, Dr. Xie and his colleagues are working to develop new treatments for cancer, heart and kidney disease.
Dr. Xie holds international patents and patent applications on seven medical inventions resulting from his research. He has served as principal investigator, project leader or co-investigator on National Institutes of Health-funded projects totaling more than $10 million, and has established active international collaborations with total funding of more than $1 million. He has been involved with the creation of two spin-off companies from his research.
