Understanding the mechanisms by which arsenic (and other chemicals) impact development and cell fate determination
Research in the Bain laboratory focuses on the mechanisms by which cells respond to toxicants, such as arsenic, chromium, and pharmaceuticals. We are currently investigating how arsenic delays cellular and organismal differentiation and development. Arsenic is a contaminant in drinking water in many parts of the world, and has been found at appreciable levels in rice and other crops. Arsenic readily crosses the placental barrier and exposure is correlated with adverse developmental outcomes such as stillbirths, spontaneous abortions, neonatal mortality, low birth weight, delays in the use of musculature, and altered neuronal function.
We are examining arsenic’s effects on development and cellular differentiation in several different stem cell lines and in killifish embryos using a variety of molecular (microarrays, qPCR, ChiP), epigenetic (miR expression, histone modification) biochemical and immunohistochemical techniques.
Professional organizations and scientific meetings typically attending by laboratory members include the Society of Toxicology, the Society of Environmental Toxicology and Chemistry, and Pollutant Responses in Marine Organisms
