 About Publications  |  Lab Members


Dr. Lyn-Cook is currently a senior interdisciplinary research biologist in the Division of Biochemical Toxicology. She received a Ph.D. in cell and molecular biology from Atlanta University in 1981. She completed a three-year post-doctoral appointment in the Division of Biochemistry (area of Neurochemistry) at the University of North Carolina School of Medicine, Chapel Hill from 1981-1984, and then was a research associate professor in the Lineberger Cancer Research Center at the University of North Carolina School of Medicine in the area of Chemical Carcinogenesis from 1985-1988. Dr. Lyn-Cook was recruited in 1988 to NCTR’s Division of Nutritional Toxicology. She has served as a senior research biologist in the Division of Pharmacogenomics and Molecular Epidemiology and in the Office of the Associate Director for Regulatory Activities at NCTR. She also serves as NCTR liaison to the FDA Office of Women’s Health.
Dr. Lyn-Cook has received numerous awards, including:

  • M.L. Reddick Award for Achievement in Cell Biology (1979)

Research Interests

Dr. Lyn-Cook is a research biologist with vast research experience in the areas of cell and molecular biology, cancer research, pharmacogenomics, epigenetics, lupus, and sex differences in drug efficacy. Her major research expertise is in the cancer field ─ with emphasis on endometrial, pancreatic, and breast cancer ─ where she has developed in vitro assays using human cells to discover biomarkers of cancer etiology and progression, as well as to examine differences in cancer drug treatments. She has further developed a research program on sex differences in response to various drugs. Dr. Lyn-Cook focuses on drug transporters and genetic variations in genes involved in metabolism, biotransformation, and drug excretion to better understand mechanistic and toxic actions of drugs alone or in combination with dietary agents. In a collaborative project with university scientists, Dr. Lyn-Cook has initiated a research program on systemic lupus erythematosus (SLE). In this program she is investigating genetic and epigenetic mechanisms involved in SLE etiology and differences in efficacy of FDA drugs or biologics in African Americans and European American women with lupus. She has shown the importance of epigenetics in SLE by examining peripheral blood mononuclear cells and serum from lupus and age-matched control patients. She has identified potential new therapeutic targets for treating lupus patients. Currently, Dr. Lyn-Cook is examining the use of FDA-approved epigenetic drugs to treat triple-negative breast cancer, an aggressive form of cancer with many subtypes that respond to very few current drug regimens.
