Roles of H2A.Z histone variant isoforms during enterocyte-like differentiation process (RNA-Seq)

GSE232113 Homo sapiens Expression profiling by high throughput sequencing 8 samples Submitted 2024/10/15 Platform GPL18573
Summary
The involvement of the histone variant H2A.Z and its isoforms in the regulation of gene expression is an increasing exciting field considering the impact of such regulations in physio-pathology. Indeed, we and other recently showed that H2A.Z.1 and H2A.Z.2 isoforms exert cooperative or antagonistic transcriptional regulations on subsets of genes involved in key processes, such as proliferation, senescence or several organ functions. In this work, we analyze the relative role of both H2A.Z isoforms on parameters of the intestinal epithelial homeostasis. We observed that the amount of H2A.Z.1 and H2A.Z.2 at TSS and gene bodies are highly correlated and that the two H2A.Z isoforms can replace each other when depleted. We highlighted the role of their respective deposition onto chromatin by specific incorporators in some discrete isoform-specific contribution to the differentiation process. We have also uncovered an unexpected link between H2A.Z isoforms occupancy at gene bodies and the propensity of genes to be induced in enterocyte differentiation.
