OverviewAI-generated summary
Mason G. Pearce's research focuses on toxicokinetics and genotoxicity, utilizing various exposure routes and animal models, primarily Sprague-Dawley rats. His work investigates the dose-response relationships of chemical agents, including NNK, a known mutagen and carcinogen. Pearce has published studies examining the effects of agents like NNK via nose-only inhalation, intraperitoneal injection, and oral gavage, often assessing parameters such as toxicity and Haber's Rule. His research also explores the impact of life stage and tissue type on genotoxicity assessments, using agents like ethyl methane sulfonate. Further investigations involve the use of specific gene mutations, such as PIG-A, as biomarkers for mutagenicity in both animal models (F344 rats) and human populations, including cancer patients undergoing specific treatments. Pearce employs advanced sequencing techniques to evaluate mutagenicity in humans. He has a publication record of 35 papers, with 702 citations, and an h-index of 15. Key collaborators include Robert H. Heflich, Page B. McKinzie, Vasily N. Dobrovolsky, and Mackean P. Maisha, all from the National Center for Toxicological Research.
