ASP3IRE Center: Accelerating Research Translation For Children’s Environmental Health Molly Kile College of Public Health and Human Sciences Oregon State University |
Molly Kile is an environmental epidemiologist whose research focuses on understanding how exposures to chemicals influence human health. Her expertise is in conducting population-based environmental health studies and often works with communities that are disproportionately impacted by environmental pollutants. She received her doctoral degree from Harvard School of Public Health in 2006 and is currently a Professor at the College of Public Health and Human Sciences at Oregon State University. She is currently the PI on two active NIEHS-funded R01s that are studying the effects of flame retardants on children’s neurocognitive and behavioral growth and private well water stewardship. She is also interim deputy director of the Pacific Northwest Center for Translational Environmental Health Research (P30) and the co-PI of the newly formed ASPIRE Center at OSU (P2C) that is focusing on accelerating the adoption of evidence-based policies, programs, and practices that promote children’s environmental health.

Dysregulation Of Rna Metabolism In Arsenic Exposed Cells J. Christopher States Professor Department of Pharmacology and Toxicology University of Louisville |
Arsenic exposure is a global public health problem. Arsenic is a multi-organ toxicant and chronic exposure causes multiple chronic diseases including cancer. Skin cancer is the most common cancer caused by arsenic exposure but the mechanism(s) of carcinogenesis remain unclear. This presentation focuses on dysregulation of RNA metabolism in an in vitro model of skin carcinogenesis by chronic low level arsenic exposure. Dysregulated expression of microRNA and mRNAs and alternative mRNA splicing and the intersection with chromosomal instability will be discussed.

Amazon Prime for Inflammation - NLRP3 Inflammasome Activation Mechanism Reginald McNulty Assistant Professor Department of Molecular Biology and Biochemistry, The University of California Irvine |
The NLRP3 inflammasome has been identified as a key immune sensor for tissue damage. Although NLRP3 inflammasome assembly/activation leads to the production of inflammatory messengers (called cytokines) that alert the host immune system to initiate inflammatory responses, its dysregulation often results in overt diseases due to uncontrolled inflammation. Unfortunately, exposure to a number of environmental toxicants including PFAS have been shown to induce NLRP3 inflammasome activation that in turn initiates an undesirable inflammatory response, thereby causing numerous pathologies. Although stimulating agents have not been demonstrated to directly bind NLRP3, they are able to trigger mitochondrial damage and subsequent release of mitochondrial contents that somehow signal the activation of NLRP3 inflammasome. We seek to identify the mitochondrial ligand responsible for direct NLRP3 activation and probe the molecular determinants of recognition for this interaction.

Basic Principles Of Human Health Risk Assessment For Environmental Chemical Mixtures With A Focus On Estimating Risks From Hydrocarbon Mixtures Margaret Pratt Center for Public Health and Environmental Assessment US EPA |
Chemical risk assessments follow a multistep paradigm that involves identifying hazards associated with exposure to a chemical and developing quantitative dose-response information that, when combined with exposure information, is used to characterize risk and inform risk management decisions. Evaluating human health risk from exposure to mixtures rather than individual chemicals adds another level of complexity to this process. EPA’s Mixtures Guidance defines a chemical mixture as “any combination of two or more chemical substances regardless of source or of spatial or temporal proximity” and presents approaches for assessing the risks from chemical mixtures that depend on the nature of the available data. Information on the specific whole mixture of concern or a similar mixture are preferred, but frequently such data are not available. Component approaches are a third, commonly used option that allows for utilization of data on the individual components of a mixture in a process that is informed by what is known about the similarities of the mixture components. Further, a fraction-based approach consistent with EPA’s Mixtures Guidance addresses concerns regarding the effects of weathering and defines petroleum hydrocarbon fractions on the basis of expected transport in the environment and analytical methods used to identify and quantify such environmental contaminants. For petroleum hydrocarbon fractions, the fraction-based approach has been utilized to generate Provisional Peer-Reviewed Toxicity Values (PPRTVs), which are primarily derived for use by EPA’s Superfund Program. This presentation will provide an overview of approaches for estimating health risk from chemical mixtures with greater attention being given to hydrocarbon mixtures. Examples to be discussed in greater detail include estimating cancer risks from exposure to PAH mixtures using a component approach and use of a fraction approach for derivation of PPRTVs for complex mixtures of aliphatic and aromatic hydrocarbons. The views expressed in this presentation are those of the author and do not necessarily represent the views or the policies of the U.S. Environmental Protection Agency.

Placental Barrier and Fetal Exposure to Mycoestrogens Lauren Aleksunes, Pharm.D, Ph.D Professor Rutgers University |
Exposure of babies to chemicals can increase the risk of disease later in life. This presentation will discuss factors that regulate the extent to which chemicals reach the baby through the placenta. Our research team is particularly interested in fungal-derived estrogenic toxins, known as mycoestrogens, that are present in the food supply and implicated in reproductive and developmental toxicities.

Rebalancing Agrochemical Cycles: From The Molecular To Systems Level Leanne Gilbertson, PhD Associate Professor of Environmental Engineering Fulton C. Noss Faculty Fellow University of Pittsburgh |
Immense agrochemical inputs, including pesticides and nutrients, are required for crop production and their use is incredibly inefficient. When considered at the global scale, these inefficiencies have tremendous economic and environmental consequences caused by emissions to the atmosphere (e.g., greenhouse gases) and surrounding water bodies (e.g., eutrophication). There are also massive losses of embodied resources and emissions when agrochemicals do not reach their target. As such, there is an opportunity for innovative solutions to have a big impact on an industry that is critical to the wellbeing of the global population. Yet, choices we make about the raw materials we use and how we design new technologies to increase performance have upstream (e.g., embodied resources) and downstream (e.g., emissions) implications. A combined approach that involves design decisions at the molecular level with systems-level analyses is necessary to preclude shifting burdens to other life cycle stages and to uncover high impact contributors across the life cycle. In this talk, I will discuss research from my group that aims at defining and addressing agrochemical use inefficiencies in crop production, including (i) evaluating tradeoffs of proposed nanotechnology solutions, (ii) sustainably designing carriers for delivering agrochemicals more efficiently to roots, and (iii) modeling nitrate transport and uptake in soil.
