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. 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.
One project of my lab is directed at the transcriptomic and epigenetic 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. We also currently have funding to investigate the occurrence and effects of endocrine disruption due to environmental contaminants in Detroit waterbodies, exogenous factors linked to the development of childhood leukemia, occurrence of microplastics in drinking water and the consequential impact on human health, lead-induced transgenerational neurobehavioral toxicity and transcriptomic changes, and the use of novel assay systems to evaluate health effects of volatile organic chemicals.
