Mechanisms of Adult Onset and Transgenerational Disease due to Environmental Contaminants
The Baker Lab is focused on multidisciplinary, translational research that bridges human, animal and environmental health. The current work of my lab is directed at the mechanisms of adult-onset and transgenerational disease in zebrafish resulting from exposure to TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin), a known EDC of concern in humans. Specifically, we aim to inform the connection of toxicant-induced phenotypic and functional abnormalities from multiple generations with changes in genome function and epigenetic regulation, as well as to identify critical windows for biomarkers of effect and interplay among pathways mediating toxic endpoints. Thus, our research goal is to provide critical insights into transgenerational, environmentally-induced disease. In addition to human health, results from this work are being applied to wild fish populations that are experiencing population-level consequences of reduced reproductive capacity secondary to environmental toxicants in our waterways. Wild fish not only serve important ecological roles and serve as indicators of aquatic ecosystem health, but are also an increasingly important protein source for people worldwide.
