Abstract

Myelodysplastic syndrome (MDS) is considered a hematopoietic stem cell disease that is characterized by abnormal hematopoietic differentiation and a high propensity to develop acute myeloid leukemia. It is mostly associated with advanced age, but also with prior cancer therapy and inherited syndromes related to abnormalities in DNA repair. Recent technologic advances have led to the identification of a myriad of frequently occurring genomic perturbations associated with MDS. These observations suggest that MDS and its progression to acute myeloid leukemia is a genomic instability disorder, resulting from a stepwise accumulation of genetic abnormalities. The notion is now emerging that the underlying mechanism of this disease could be a defect in one or more pathways that are involved in responding to or repairing damaged DNA. In this review, we discuss these pathways in relationship to a large number of studies performed with MDS patient samples and MDS mouse models. Moreover, in view of our current understanding of how DNA damage response and repair pathways are affected by age in hematopoietic stem cells, we also explore how this might relate to MDS development.

  • MDS is a heterogeneous group of clonal haematopoietic disorders characterized by ineffective haematopoiesis and DNA damage accumulation in haematopoietic stem and progenitor cells.

    “MDS is a heterogeneous group of clonal haematopoietic disorders characterized by ineffective haematopoiesis and DNA damage accumulation in haematopoietic stem and progenitor cells87.”

    From Telomere dysfunction in ageing and age-related diseases (2022) · cites this paper as [87]

    The Introduction describes MDS as a group of HSC-based disorders characterized by ineffective differentiation, and the genomic-instability section discusses accumulating genetic alterations. But the paper does not establish DNA damage accumulation in MDS haematopoietic stem and progenitor cells as a defining characteristic; its direct evidence of increased DNA damage concerns bone marrow cells in MDS mouse models (DNA repair > Double strand break repair; page unavailable).

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.
