Abstract

Loss of the de novo DNA methyltransferases Dnmt3a and Dnmt3b in embryonic stem cells obstructs differentiation; however, the role of these enzymes in somatic stem cells is largely unknown. Using conditional ablation, we show that Dnmt3a loss progressively impairs hematopoietic stem cell (HSC) differentiation over serial transplantation, while simultaneously expanding HSC numbers in the bone marrow. Dnmt3a-null HSCs show both increased and decreased methylation at distinct loci, including substantial CpG island hypermethylation. Dnmt3a-null HSCs upregulate HSC multipotency genes and downregulate differentiation factors, and their progeny exhibit global hypomethylation and incomplete repression of HSC-specific genes. These data establish Dnmt3a as a critical participant in the epigenetic silencing of HSC regulatory genes, thereby enabling efficient differentiation.

  • DNMT3A loss-of-function does not lead to global DNA methylation changes.

    “This reinforces previous findings that DNMT3A loss-of-function does not lead to global DNA methylation changes (15,16,19)”

    From <i>Txnip</i> Enhances Fitness of <i>Dnmt3a</i> -Mutant Hematopoietic Stem Cells via <i>p21</i> (2022) · cites this paper as [15]

    The Results section reports no overall difference in whole-genome 5-methylcytosine levels between transplanted control and Dnmt3a-null hematopoietic stem cells. This supports the claim for those cells, but not an unqualified statement about DNMT3A loss-of-function in other cell types. The same section also reports methylation changes at specific genomic regions. (LLM, conf=0.82)

  • Dnmt3a−/− HSCs demonstrate defective differentiation and enhanced self-renewal.

    “prior studies showed that Dnmt3a−/− HSCs demonstrate defective differentiation and enhanced self-renewal (Challen et al., 2011; Jeong et al., 2018)”
  • Mouse models show Dnmt3a loss-of-function skews hematopoietic stem cell fate decisions toward self-renewal, facilitating clonal expansion in the bone marrow.

    “Mouse models show Dnmt3a loss-of-function skews HSC fate decisions toward self-renewal, facilitating clonal expansion in the bone marrow (BM; ref. 15,16).”
  • Analysis of DNA methylation and gene expression patterns in mouse and human systems has yet to identify a unifying molecular mechanism to explain the increased fitness of Dnmt3a-mutant hematopoietic stem cells.

    “However, analysis of DNA methylation and gene expression patterns in mouse (15,17) and human (17,18) systems have yet to identify a unifying molecular mechanism to explain the increased fitness of these mutant HSCs.”
  • Genetic deletion of IFNgr1 in Dnmt3a KO hematopoietic stem cells normalized gene expression, including the previously reported upregulation of hematopoietic stem cell stemness genes.

    “In support of the functional data, genetic deletion of IFNgr1 in Dnmt3a KO HSCs normalized gene expression, including the previously reported (15) upregulation of HSC “stemness” genes (Supplementary Fig. S5A).”

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.
