This file contains summary data of thyroid hormones in serum and brain in rat dams and their pups following maternal exposure to a perflorinated substance, PFHxS and an antimicrobial, Triclosan. Gene expression in thyroid glands and liver and brain were investigated. Anatomical and bahavioral indices of developmental neurotoxicity were assessed. Result so fall of these inquiries are summarized in these datasets. This dataset is associated with the following publication: Gilbert, M.E., K. OShaughnessy, S. Thomas, C. Riutta, C. Wood, A.

This study looked at functional endpoints in adult offspring of rats exposed in utero and postnatally to an environmentally relevant mixture of PCBs, Fox River blend. A model of neural plasticity and epilepsy, electrical kindling, was examined. Animals exposed to PCBs had slower kindling rates suggesting impaired plasticity mechanisms, consistent with previous work with PCBs where deficits were seen in another plasticity model, long-term potentiation.

Adequate levels of thyroid hormones (TH) are needed for proper brain development, deficiencies may lead to adverse neurological outcomes in humans and animal models. Environmental chemicals have been linked to TH disruption, yet the relationship between developmental exposures and decline in serum TH resulting in neurodevelopmental impairment is poorly understood. The present study developed a quantitative adverse outcome pathway (qAOP) where serum thyroxin (T4) reduction following inhibition of thyroperoxidase in the thyroid gland are described and related to deficits in fetal brain TH and the development of a brain malformation, subcortical band heterotopia. Pregnant dams were exposed to 6-propylthiouracil (PTU 0, 0.1, 0.5, 1, 2, or 3 ppm) from gestational day 6-20, increasing PTU concentrations in maternal thyroid gland and serum as well as in fetal serum. Dams exposed to 0.5 ppm PTU and higher exhibited dose-dependent decreases in thyroidal T4. Serum T4 levels in the dam were significantly decreased with exposure to 2 and 3 ppm PTU. In the fetus, T4 decrements were first observed at a lower dose of 0.5 ppm PTU. Based on these data, fetal brain T4 levels were estimated from published literature sources, and quantitatively linked to increases in the size of the heterotopia present in the brains of offspring. These data show the potential of in vivo assessments and computational descriptions of biological responses to predict the development of this structural brain malformation and use of qAOP approach to evaluate brain deficits that may result from exposure to other TH disruptors.
