Polychlorinated biphenyls (PCBs) are persistent environmental toxicants, present in 100% of US adults and dose-dependently associated with nonalcoholic fatty liver disease (NAFLD) in epidemiologic studies. PCBs are predicted to interact with receptors previously implicated in xenobiotic/energy metabolism and NAFLD. These receptors include the aryl hydrocarbon receptor (AhR), pregnane xenobiotic receptor (PXR), constitutive androstane receptor (CAR), peroxisome proliferator-activated receptors (PPARs), liver-X-receptor and farnesoid-X-receptor. This study evaluated the hepatic effects of the PCB mixture, Aroclor 1260, whose composition mimics human bioaccumulation patterns, in a mouse model of diet-induced obesity. Male C57Bl/6J mice were fed a control or 42% high fat diet (HFD) …
