Sex differences in Non-Alcoholic Steatohepatitis (NASH) in mice evoked by a fructose-palmitate-cholesterol (FPC)-enriched diet [bulk_isolated_cells]

To study sex differences in the response to NASH in mice, single nucleus RNA sequencing of livers was performed. Single nucleus RNAseq demonstrated enrichment of differentially-expressed genes particularly in hepatocytes and stellate cells in females versus males fed FPC-NASH. Multiple regulons (transcription factors and target genes) implicated in lipid and other metabolic processes and hormone signaling (hepatocytes) and cell-cell communication and cell adhesion (stellate cells) were noted, which were enriched in female versus male FPC-NASH diet. Bulk liver RNAseq and RNAseq of isolated hepatocytes and hepatic stellate cells were analyzed as validation experiments. Overall design: Male and female C57BL/6J mice were fed fructose-palmitate-cholesterol (FPC-NASH) diet or standard chow (SC) for 16 weeks. Hepatocytes and hepatic stellate cells were isolated from from control and FPC diet fed male and female mice (N = 4 independent mice/group) and processed for bulk RNAseq.
