Abstract

Genome sequencing studies of patient samples have implicated the involvement of various components of the epigenetic machinery in myeloid diseases, including the de novo DNA methyltransferase DNMT3A. We have recently shown that Dnmt3a is essential for hematopoietic stem cell differentiation. Here, we investigated the effect of loss of Dnmt3a on hematopoietic transformation by forcing the normally quiescent hematopoietic stem cells to divide in vivo. Mice transplanted with Dnmt3a-null bone marrow in the absence of wildtype support cells succumbed to bone marrow failure (median survival, 328 days) characteristic of myelodysplastic syndromes with symptoms including anemia, neutropenia, bone marrow hypercellularity, and splenomegaly with myeloid infiltration. Two out of 25 mice developed myeloid leukemia with >20%blasts in the blood and bone marrow. Four out of 25 primary mice succumbed to myeloproliferative disorders, some of which progressed to secondary leukemia after long latency. Exome sequencing identified cooperating c-Kit mutations found only in the leukemic samples. Ectopic introduction of c-Kit variants into a Dnmt3a-deficient background produced acute leukemia with a short latency (median survival, 67 days). Our data highlight crucial roles of Dnmt3a in normal and malignant hematopoiesis and suggest that a major role for this enzyme is to facilitate developmental progression of progenitor cells at multiple decision checkpoints.

  • Dnmt3a heterozygous hematopoietic stem cells produce only modest phenotypes in mice.

    “However, we and others have shown that Dnmt3a HET HSCs produce only modest phenotypes in mice (25,26), likely because these variants provide very minor fitness advantages to HSCs (2) that require the extended lifespan of humans to manifest measureable phenotypes.”
  • Stem cells from mice with loss-of-function mutations in TET2 or DNMT3A are able to serially replate in colony forming assays over many generations, whereas wild-type stem cells quickly lose this capacity, suggestive of enhanced self-renewal capacity in the mutant stem cells.

    “Stem cells from these mice are able to serially replate in colony forming assays over many generations, whereas wild-type stem cells quickly lose this capacity, suggestive of enhanced self-renewal capacity in the mutant stem cells 54,55.”

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.
