A new multi-PI R01 titled “Genetic Factors that Influence Arsenic Toxicity,” has been awarded to Principal Investigators Gary A. Churchill, Ron Korstanje, and Laura G. Reinholdt for November 1, 2018 through October 31, 2023.
Project Narrative:
Regulatory toxicology seeks to create safety thresholds for chemical exposure in humans based on experimental studies in animals, but results of such studies may not accurately predict human sensitivity because they fail to accommodate the genetic diversity that exists across human populations. We will use population-based, genetically diverse mice to study the complex interplay between genetic variation and environmental factors that determine cellular and organismal responses to arsenic exposure. Through a novel statistical analysis of our data, we will account for individual genetic variation and provide a data-driven model that can be translated to risk assessment for human chemical exposure.
