Transcriptional regulation of liver lipotoxicity in non-alcoholic steatohepatitis [ATAC-seq]


ABSTRACT: Non-alcoholic fatty liver disease is continuum of disorders among which non-alcoholic steatohepatitis (NASH) is particularly associated with a negative prognosis. Hepatocyte lipotoxicity is one of the main pathogenic factors of liver fibrosis and NASH. However, the molecular mechanisms regulating this process are poorly understood. Here, we integrated transcriptomic and chromatin accessibility analyses from human liver and mouse hepatocytes to identify lipotoxicity-sensitive transcription factors. We found that several transcription factors that were activated in liver from NASH patients and by mouse hepatocyte lipotoxicity. Notably, the gene expression linked to lipotoxicity closely correlated with transcriptional patters in fibrosis progression in NASH patients. Collectively, our findings uncovered novel molecular insights into lipotoxicity-induced NASH.
