Abstract: Abstract Persistent exposure to man-made endocrine disrupting chemicals during fetal endocrine development may lead to disruption of metabolic homeostasis contributing to childhood obesity. Limited cellular platforms exist to test endocrine disrupting chemical-induced developmental abnormalities in human endocrine tissues. Here we use an human-induced pluripotent stem cell-based platform to demonstrate adverse impacts of obesogenic endocrine disrupting chemicals in the developing endocrine system. We delineate the effects upon physiological low-dose exposure to ubiquitous endocrine disrupting chemicals including, perfluoro-octanoic acid, tributyltin, and butylhydroxytoluene, in endocrine-active human-induced pluripotent stem cell-derived foregut epithelial cells and hypothalamic neurons. Endocrine disrupting chemicals induce endoplasmic reticulum stress, perturb NF-κB, and p53 signaling, and diminish mitochondrial respiratory gene expression, spare respiratory capacity, and ATP levels. As a result, normal production and secretion of appetite control hormones, PYY, α-MSH, and CART, are hampered. Blocking NF-κB rescues endocrine disrupting chemical-induced aberrant mitochondrial phenotypes and endocrine dysregulation, but not ER-stress and p53-phosphorylation changes.
