Abstract

The functional potential of hematopoietic stem cells (HSCs) declines during aging, and in doing so, significantly contributes to hematopoietic pathophysiology in the elderly. To explore the relationship between age-associated HSC decline and the epigenome, we examined global DNA methylation of HSCs during ontogeny in combination with functional analysis. Although the DNA methylome is generally stable during aging, site-specific alterations of DNA methylation occur at genomic regions associated with hematopoietic lineage potential and selectively target genes expressed in downstream progenitor and effector cells. We found that age-associated HSC decline, replicative limits, and DNA methylation are largely dependent on the proliferative history of HSCs, yet appear to be telomere-length independent. Physiological aging and experimentally enforced proliferation of HSCs both led to DNA hypermethylation of genes regulated by Polycomb Repressive Complex 2. Our results provide evidence that epigenomic alterations of the DNA methylation landscape contribute to the functional decline of HSCs during aging.

  • Several genome-wide studies have not found a correlation between age-dependent differential DNA methylation and altered gene expression.

    “Surprisingly, several genome-wide studies have not found a correlation between age-dependent differential DNA methylation and altered gene expression (Beerman et al., 2013; Yuan et al., 2015).”

  • Loci with age-associated DNA hypermethylation in stem cells are enriched for genes normally repressed by Polycomb repressive complex.

    “Interestingly, studies in stem cells have also demonstrated that loci with age-associated DNA hypermethylation are enriched for genes normally repressed by Polycomb repressive complex, the complex that methylates H3K27 (Beerman et al., 2013; Sun et al., 2014; Teschendorff et al., 2010).”

  • Aged stem cell populations have a unique chromatin state and gene expression profile compared with youthful stem cells.

    “Compared to youthful stem cells, aged stem cell populations have a unique chromatin state and gene expression profile (Beerman et al., 2013; Liu et al., 2013; Sun et al., 2014).”

  • DNA methylation tends to increase with age at some CpG islands, particularly at polycomb target genes and at promoters of tumour suppressor genes.

    “DNA methylation tends to increase with age at some CpG islands, particularly at polycomb target genes 55,56 and at promoters of tumour suppressor genes 57 .”
  • A limited number of genomic loci gain DNA methylation during ageing and in cancer, in particular CpG islands in promoters of tumour suppressor genes and polycomb targets.

    “A limited number of genomic loci gain DNA methylation during ageing and in cancer, in particular CpG islands in promoters of tumour suppressor genes (TSGs) and polycomb targets 57 .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
