MiRNA seq mouse liver HFD, PCB126, Aroclor1260 exposure


ABSTRACT: Exposure to high fat diet (HFD) and persistent organic pollutants including polychlorinated biphenyls (PCBs) is associated with liver injury in human populations and with non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) in animal models. Exposure of HFD-fed male mice to the non-dioxin-like (NDL) PCB mixture Aroclor1260 or to dioxin-like (DL) PCB126 or to the combination caused steatohepatitis and differentially altered the liver proteome with pathways involving epigenetic regulation of gene expression. Here unbiased RNA sequencing of miRNA (miRNA-seq) and subsequent network analysis to characterize the biological pathways altered by HFD and PCB exposure compared to HFD alone. Distinct miRNA expression patterns reveald a potential role of miRNAs in the pathogenesis of NAFLD. These results demonstrate miRNA and transcriptome pathways in PCB-related hepatic inflammation and fibrosis in a mouse model of NAFLD.
