Background

Dr. Nan Mei received his M.D. in 1984 from the Hebei Medical University in China and his Ph.D. degree in 1997 from the University of Occupational and Environmental Health in Japan. He began his scientific career in clinical cancer research in 1988 at the 4th Hospital of Hebei Medical University in China. He worked as a postdoctoral follow in the Department of Experimental Oncology, Cross Cancer Institute in Canada from 1998 to 2001, and as a research fellow in the Department of Environmental Oncology, Institute of Industrial Ecological Sciences in Japan from 2001 to 2002. He joined NCTR as an ORISE research fellow in the Division of Genetic and Molecular Toxicology in 2002, and became an FDA research biologist in 2005. During his research career, Dr. Mei has published 92 peer-reviewed research articles in scientific journals and 12 book chapters. He has given 32 oral presentations at national and international scientific meetings.

Research Interests

Dr. Mei’s research program is focused on using appropriate in vivo and in vitro mutation assays and toxicogenomic techniques to provide key toxicological information for FDA priority chemicals. He utilizes the 1) in vivo cII transgenic mutation assay (mouse and rat), 2) in vitro standard test battery for genotoxicity, 3) gene expression and pathway analysis to evaluate FDA-relevant chemicals or model carcinogens for their mutagenicity and for determining the mechanisms involved in chemically induced genetic toxicity. His completed and ongoing projects include the evaluation of the mutagenic effects of direct mutagens, herbal dietary supplements, industrial compounds, nanoparticles, ingredients in cosmetics and other retail products, and tobacco products. Dr. Mei has incorporated toxicogenomic approaches into his research to elucidate molecular mechanisms and create gene signatures for developing potential biomarkers. His research results demonstrate that both in vivo and in vitro mutation assays serve as reliable tools for detecting the types of mutations found in cancer genes, and are useful for the hazard identification portion of human risk assessment.
