Diabetes remains a leading cause of death nationwide despite pharmacological advances. Recent etiological investigations of the disease detail the role of perinatal exposure to environmental contaminants, such as polychlorinated biphenyls (PCBs), in enhancing disease susceptibility. Polychlorinated biphenyl 126, a coplanar PCB, elicits its toxic effects through the aryl-hydrocarbon receptor and the disruption of endocrine signaling. The goal of this dissertation was to focus on delineating the differences in the developmental windows of diabetes susceptibility respective to the timing of PCB126 exposure and to understand the influence of maternal exercise and nuclear-factor erythroid-2-related factor 2 (Nrf2) expression in combating the negative …

Cardiovascular disease (CVD) is the leading cause of death worldwide and is partially attributed to perturbations in lipid metabolism. Xenobiotics, such as pharmaceutical drugs and environmental chemicals, have been associated with increased risk of CVD in multiple large-scale human population studies, but the underlying mechanisms remain poorly defined. We and others have identified several xenobiotics as potent agonists for the pregnane X receptor (PXR), a nuclear receptor that can be activated by numerous drugs as well as environmental and dietary chemicals. However, the role of PXR in mediating the pathophysiological effects of xenobiotic exposure in humans and animals remains elusive. …
