Mapping of histone modifications in aged hematopoietic stem cells (HSCs)
The decline of hematopoietic stem cell (HSC) function upon aging contributes to senescent immune remodeling and to leukemia pathogenesis. Aged HSCs show epigenetic alterations affecting DNA methylation, histone modifications, and show a reduction in the polar distribution of histone 4 lysine 16 acetylation (H4K16ac). Here, we determined the deposition patterns of H4K16ac in young, aged and re-juvenated HSCs using ChIP-seq. Overall design: Examination of histone modifications in young, aged and aged/re-juvenated HSCs
