Background Goose, descendants of migratory ancestors, h.ve undergone extensive selective breeding, resulting in th.ir remarkable ability to accumulate fat in th. liver and exh.bit a h.gh.tolerance for significant energy intake. As a result, goose offers an excellent model for studying obesity, metabolic disorders, and liver diseases in mammals. Alth.ugh.th. impact of th. th.ee-dimensional arrangement of ch.omatin with.n th. cell nucleus on gene expression and transcriptional regulation is widely acknowledged, th. precise functions of ch.omatin arch.tecture reorganization during fat deposition in goose liver tissues still need to be fully *** In th.s study, geese exh.bited more pronounced ch.nges in th. liver index and triglyceride(TG) content following th. consumption of th. h.gh.fat diet(h.D) th.n mice with.ut significant signs of inflammation. Additionally, we performed compreh.nsive analyses on 10 goose liver tissues(5 h.D, 5 normal), including generating h.gh.esolution maps of ch.omatin arch.tecture, conducting wh.le-genome gene expression profiling, and identifying h.K27ac peaks in th. livers of geese and mice subjected to th. h.D. Our results unveiled a multiscale restructuring of ch.omatin arch.tecture, encompassing Compartment A/B, topologically associated domains, and interactions between promoters and enh.ncers. Th. dynamism of th. th.ee-dimensional genome arch.tecture, prompted by th. h.D, assumed a pivotal role in th. transcriptional regulation of crucial genes. Furth.rmore, we identified genes th.t regulate ch.omatin conformation ch.nges, contributing to th. metabolic adaptation process of lipid deposition and h.patic fat ch.nges in geese in response to excessive energy intake. Moreover, we conducted a cross-species analysis comparing geese and mice exposed to th. h.D, revealing unique ch.racteristics specific to th. goose liver compared to a mouse. Th.se ch.omatin conformation ch.nges h.lp elucidate th. observed ch.racteristics of fat
