WebMar 7, 2024 · Setd8 deficient cells also had a significant disruption of erythroid gene expression. They were able to express erythroid-specific genes, such as the globins, but were unable to repress the non-erythroid transcriptome, accompanied by an increase in chromatin accessibility at those loci. (Myers et al., 2024). WebErythropoiesis is the biological process that consumes the highest amount of body iron for heme synthesis. Heme synthesis in erythroid cells is finely coordinated with that of alpha (α) and beta (β)-globin, resulting in the production of hemoglobin, a tetramer of 2α- and 2β-globin chains, and heme as the prosthetic group. Heme is not only the structural …
