Exposures and Latent Disease Risk: Session III - Arsenic as a Case Study

Sponsored by: NIEHS Superfund Research Program

Go to Archive

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on understanding the health effects of exposures when there is a lag between exposure and the onset of the disease.

In the third session, presenters will describe studies linking early-life arsenic exposure and later-life disease risk. The focus on arsenic as a case study may also provide insights into linking other exposures to latent disease risk and identifying windows of susceptibility.

Yu Chen, Ph.D., and Maria Argos, Ph.D., co-investigators of a project with the Columbia University SRP Center, will present research from the Health Effects of Arsenic Longitudinal Study (HEALS) and ancillary studies linking early-life arsenic exposure and disease risk across the life course. For nearly two decades, HEALS has provided individual-level epidemiologic data evaluating risks from chronic arsenic exposure through drinking water in rural Bangladesh with clinical and molecular endpoints.

Fenna Sillé, Ph.D., assistant professor at the Johns Hopkins University Bloomberg School of Public Health, will discuss her research focused on early-life exposures to arsenic and immune system changes. As an alumna of the University of California, Berkeley SRP Center, she will also discuss studies assessing the long-term effects of a unique early-life arsenic exposure situation in Northern Chile. She will present data from in vitro and in vivo models as well as from the Chilean population study.

Erik Tokar, Ph.D., leader of the NIEHS National Toxicology Program Stem Cell Toxicology Group, will discuss the association between early-life arsenic exposure and cancer in adulthood. His presentation will focus on cancer formation in adulthood following in utero and "whole life" exposure to arsenic. It will cover in vivo and in vitro models and discuss the effects of arsenic on stem cell recruitment and the microenvironment during transformation and cancer stem cell formation.

Yu Chen, Ph.D., is a professor at New York University (NYU) in the Department of Population Health and the Department of Environmental Medicine. She is a chronic disease epidemiologist involved in multidisciplinary research that focuses on how host and environmental factors are related to chronic diseases, including cardiovascular disease and cancer. For nearly two decades, she has worked with colleagues from Columbia University and the University of Chicago to study health effects of arsenic exposure in the Health Effects of Arsenic Longitudinal Study (HEALS) in Bangladesh. She leads another project with colleagues at Vanderbilt University to investigate the role of the gastric and oral microbiome in gastric premalignant and malignant lesions. She also conducts research using resources from the NYU Women's Health Study and the Asia Cohort Consortium. Chen is a recipient of the Outstanding New Environmental Scientist Award from NIEHS. She directs a course on epidemiology methods for graduate students at NYU School of Medicine. She received her Ph.D. with distinction in epidemiology from Columbia University in 2005.

Maria Argos, Ph.D., is an associate professor of epidemiology at the University of Illinois at Chicago School of Public Health. Her research focuses on the environmental and molecular epidemiology of chronic diseases, with particular emphasis on the health effects of metal exposures. Her research also has a strong focus on identifying molecular pathways altered by environmental exposures that influence disease risk by leveraging high-dimensional molecular data and biomarker data obtained from biological specimens collected in the epidemiological setting. She is the principal investigator of the Bangladesh Environmental Research in Children's Health (BIRCH) cohort that aims to evaluate early life health effects of arsenic exposure and metal mixtures. She is also a co-investigator of the Health Effects of Arsenic Longitudinal Study (HEALS) and the Columbia University SRP Center. She holds an M.P.H. degree in Environmental Health Sciences and a Ph.D. degree in Epidemiology from Columbia University.

Fenna Sillé, Ph.D., is an assistant professor at the Johns Hopkins University Bloomberg School of Public Health. She is researching how early-life exposures change the immune system and increase the risk of respiratory infections and lung cancer later in life. Her lab currently focuses on the effect of arsenic exposure on tuberculosis, influenza, and vaccine efficacy. Prior to joining Johns Hopkins, Sillé was a postdoctoral fellow at UC Berkeley. As an alumna of the UC Berkeley SRP Center, she collaborates with Craig Steinmaus, M.D., and Martyn Smith, Ph.D., as well as Catterina Ferreccio, M.D., MPH (Pontificia Universidad Católica de Chile) on studies assessing the long-term effects of a unique early-life arsenic exposure situation in Northern Chile.
