Mingyao Liu
Biography
Mingyao Liu received his B.S. and M.S. from Hunan Normal University in Hunan, China, and earned his Ph.D. in cell biology in 1992 from the University of Maryland, College Park, Maryland. He was a postdoctoral fellow for two years in the Department of Neuroscience, Johns Hopkins University School of Medicine, Maryland, and held another postdoctoral position from 1994 to 1998 in the Division of Biology, California Institute of Technology, Pasadena, California. He is an Associate Professor in the Institute of Biosciences and Technology's Center for Cancer Biology and Nutrition with a joint appointment in the Department of Medical Biochemistry and Genetics, Texas A&M University.
Research
Our laboratory studies how cells receive and process information from their chemical and physical environments under normal and disease conditions. In particular, our research interests focus on understanding the biochemical properties and cellular functions of GTP-binding proteins (small and heterotrimeric), their receptors and signaling pathways in cell growth, proliferation, and differentiation. Our current projects include: 1) G-protein coupled receptors and signaling pathways in cell growth and differentiation; 2) Biochemical properties and cellular functions of GTP-binding proteins, their regulators and effectors in normal and human disease conditions; 3) Molecular mechanisms of human stem cell differentiation. A multi-faceted approach (biochemistry, cell and molecular biology, genetics, and mouse models) is taken in our studies, with the ultimate goal of understanding the regulation of cell growth, differentiation, and proliferation.
