# Effects-Related Biomarkers of Environmental Neurotoxic Exposures

> **NIH NIH P42** · UNIVERSITY OF WASHINGTON · 2020 · $10,800

## Abstract

PROJECT SUMMARY
This proposal is for a 5-year competing renewal of the University of Washington (UW) Superfund Research
Program (SRP). The overarching theme of the program is to investigate the mechanisms and ramifications of
metal neurotoxicity in humans and aquatic species. Based upon our work, we are developing biomarkers
predictive of; 1) exposure to neurotoxic agents, 2) early indicators of neurotoxic injury at the cellular and
organismal levels, and/or 3) genetic determinants that underlie unusual susceptibility to environmental
neurotoxicants. The physiological processes under investigation adversely affect cognition, olfaction and
neurobehavioral processes, and are associated with the risk of developing Alzheimer's and non-Alzheimer's
related dementia, Parkinson's disease, and other neurodevelopmental diseases. Our research focuses upon
metals that commonly occur at Superfund hazardous waste sites for which there are important data gaps
impeding the full understanding of their neurotoxic effects on human health and aquatic species. These data
gaps include an understanding of mechanisms of toxicity, inter-individual or gender susceptibility, and
biogeochemical factors that govern their fate in their environment. A key theme of our projects is addressing
the role of cellular oxidative stress during metal-induced neurotoxicity. The UW program will include four
research projects (two environmental science and two biomedical projects). The research projects include
investigations of (1) mechanisms and biomarkers of metal olfactory injury to Pacific salmon, with a primary
focus on cadmium; (2) cellular and molecular mechanisms of cadmium-mediated neurotoxicity in rodents,
including effects on olfaction and cognition; (3) the role of paraoxonases as modifiers of cadmium and
manganese neurotoxicity; and (4) biogeochemistry and bioavailability of arsenic in an urbanized lake system in
Washington State. Our projects include collaborations among projects and cores, and each project is
interdisciplinary in nature. The UW SRP includes a Training Core that is multi- and interdisciplinary, and will
support predoctoral trainees from participating departments. The Research Translation Core will continue to
ensure timely and appropriate communication of our research findings to NIEHS and other appropriate
stakeholders, partner effectively with agencies, identify potential patents, and develop and support translation
opportunities with other end-users of our scientific findings. The Community Engagement Core (a new Core
beginning with 2015 funding) will build upon existing partnerships and expand partnerships with other
communities, such as those directly affected by the toxicants we are studying, and with other community
groups that have concerns about environmental toxicants. The Administrative Core will stimulate interactions
among projects and cores ensuring full program integration, assure appropriate communication with NIEHS
and other governmental age...
