Evaluating The Effects Of Pcbs In Non-Alcoholic Fatty Liver Disease & Diabetes And The Role Of Ahr In Regulating The Hepatic Proteome And Lipid Metabolism., Jian Jin
Electronic Theses and Dissertations
Polychlorinated biphenyls (PCBs) are persistent organic pollutants associated with non-alcoholic fatty liver disease (NAFLD) and diabetes. Based on their ability to activate the aryl hydrocarbon receptor (AhR), PCBs are subdivided into two classes: dioxin-like (DL) and non- dioxin-like (NDL) PCBs. This study not only evaluated the chronic effect of DL PCBs (PCB126), NDL PCBs (Aroclor1260 mainly contains NDL), and the DL/NDL PCB mixture (PCB126/Aroclor1260 mixture) on liver, but also explored the acute hepatic effects of DL PCB and potential mechanisms in NAFLD and the role of AhR in regulating hepatic proteome and lipid metabolism, and whether the process independent of …

Electronic Theses and Dissertations
This dissertation describes how poly-chlorinated biphenyls (PCBs) exacerbate the pathogenesis of non-alcoholic fatty liver disease (NAFLD). While PCBs were banned in 1979, they still persist in contaminated biota, including food, and are detected in human plasma and adipose. The body burden of PCBs is associated with elevation of liver enzymes and necrosis markers in humans, characteristic of NAFLD. PCB exposure in high-fat diet fed mice leads to steatohepatitis that recapitulate the findings seen in exposed humans. The global estimate of people diagnosed with NAFLD is up to 1 in 4 people, unrelated to dietary or genetic factors. The hepatic mechanisms …
