Dr. Rui-Ping Xiao was trained as a physician-scientist in both China and the United States. She received her M.D. and medical training at Tong-Ji Medical University, China. In 1988, she went to the United States, and spent 20 years in National Institute on Aging (NIA), NIH, from a postdoctoral fellow to a tenured Senior Investigator and the Chief of the Receptor Signaling Section. Overlapping with her training at NIH, she also completed her Ph.D. study in the Medical School of University of Maryland from 1991 to 1995. Additionally, in 2005, she was invited by Peking University to serve as the Founding Director of the Institute of Molecular of Medicine (IMM) at Peking University (initially as a volunteer), and became a full-time returnee.
Dr. Xiao has made important discoveries in beta-adrenergic receptor (AR) subtype signaling, with an emphasis on translating bench discoveries to the bedside. She was the first to show that?beta2-AR dually couples to Gs and Gi, revealing a new signaling paradigm of the G protein-coupled receptor superfamily. While chronic beta1-AR stimulation causes heart cell death and cardiomyopathy by Ca2+/calmodulin kinase II-dependent pathways, beta2-AR is cardiac protective. She co-invented the Gs-biased, chiral beta2-AR agonist R,R-feneterol and co-supervised its Phase I clinical trial (Phase II planned), spearheading a novel therapy treating heart failure with beta2-AR agonist R,R-feneterol or derivatives combined with beta1-AR blocker. Her current research has revealed that MG53 E3 ligase-mediated, ubiquitin-dependent degradation of insulin receptor and insulin receptor substrate 1 constitutes a fundamental mechanism for the development of systemic insulin resistance, leading to the sequelae of metabolic syndrome and cardiovascular complications. She has authored >140 peer-reviewed publications. She has been global leader in biomedical research and served as the founding director of the Institute of Molecular Medicine, Peking University since 2005. She has also played a leadership role in clinical translational research and currently serves as an Associate Editor of The New England Journal of Medicine.
