RESUMEN
Bisphenol F (BPF), a substitute for bisphenol A (BPA), is ubiquitous existed in various environmental media. Exposure to BPF may promote non-alcoholic fatty liver disease (NAFLD), while the potential mechanism is still unknown. In current study, we used in vitro and in vivo model to evaluate its hepatotoxicity and molecular mechanism. Using multi-omics approach, we found that BPF exposure led to changes in hepatic transcriptome, metabolome and chromatin accessible regions that were enriched for binding sites of transcription factors in bZIP family. These alterations were enriched with pathways integral to the endoplasmic reticulum stress and NAFLD. These findings suggested that BPF exposure might reprogram the chromatin accessibility and enhancer landscape in the liver, with downstream effects on genes associated with endoplasmic reticulum stress and lipid metabolism, which relied on bZIP family transcription factors. Overall, our study describes comprehensive molecular alterations in hepatocytes after BPF exposure and provides new insights into the understanding of the hepatoxicity of BPF.
