Catherine D. Mao, Ph.D.
Research Faculty, Department of Clinical Sciences
Division of Clinical Nutrition
Dr. Mao received her BS in Biochemistry/Molecular Biology and Ph. D in Microbiology from the University Paris 7-Rene Diderot (Paris, France) followed by a post-doctoral fellowship at the Imperial Cancer Research Fund (now Cancer Research-UK) (London, United Kingdom). Her research work has been funded by the American Cancer Society, the American Heart Association and the National Institute of Health.
- Member of the Graduate Center for Nutritional Sciences
- Member of the Markey Cancer Center-Cancer Cell Biology/Signaling group
- Dr. Mao served for a 4 year term (2004-2007) on the American Heart Association-Ohio Valley Affiliate Committee 5C study section: Basic Cell and Molecular Biology
- Member of the American Society for Cell Biology
- Member of the North American Vascular Biology Organization
Dr. Mao research interests are centered on the cellular signaling and mechanisms controlling endothelial cell homeostasis and behavior in physiological conditions (growth and tissue repair) and pathophysiological conditions (tumor development, metastatic tumor progression, and other age-related diseases such as diabetes) with a particular focus on the Wnts and Wnt-signaling components and their regulation by lithium and the cellular metabolic redox-states. She is currently funded by the National Institute on Aging to study the transcriptional regulation of the matrix-metalloproteinase 1 during endothelial cell senescence and the role of the matrix-metalloproteinase 1/protease activated receptor axis in the establishment and reinforcement of cell senescence.
