Heterochromatin rewiring and domain disruption-mediated chromatin compaction during erythropoiesis [HiChIP]

Project description:Erythropoiesis in mammalian involves chromatin compaction which is initiated in the early stage of terminal differentiation. The proper condensation of chromatin is essential for the subsequent enucleation of erythroblast, but the characteristics of chromatin compaction and chromatin architecture changes in erythropoiesis are poorly understood. Here, we show that the formation of H3K9me3 long-range interactions which mediated heterochromatin three-dimensional rewiring participant in human erythroid chromatin condensation. TADs structure attenuated and boundary strength weakened globally but selectively maintaining in active chromatin region during terminal erythropoiesis. We demonstrate that the erythroid master regulators GATA1 safeguard the active chromatin structure and ensure the appropriate gene expression, under the chromatin condensation of human terminal erythropoiesis
