Abstract

Cancer-associated IDH mutations are characterized by neomorphic enzyme activity and resultant 2-hydroxyglutarate (2HG) production. Mutational and epigenetic profiling of a large acute myeloid leukemia (AML) patient cohort revealed that IDH1/2-mutant AMLs display global DNA hypermethylation and a specific hypermethylation signature. Furthermore, expression of 2HG-producing IDH alleles in cells induced global DNA hypermethylation. In the AML cohort, IDH1/2 mutations were mutually exclusive with mutations in the α-ketoglutarate-dependent enzyme TET2, and TET2 loss-of-function mutations were associated with similar epigenetic defects as IDH1/2 mutants. Consistent with these genetic and epigenetic data, expression of IDH mutants impaired TET2 catalytic function in cells. Finally, either expression of mutant IDH1/2 or Tet2 depletion impaired hematopoietic differentiation and increased stem/progenitor cell marker expression, suggesting a shared proleukemogenic effect.

  • 2-hydroxyglutarate interferes with iron-dependent hydroxylases, including the TET family of 5-methylcytosine hydroxylases.

    “Mutant IDH protein produces a novel onco-metabolite, 2-hydroxyglutarate (2-HG), that interferes with iron-dependent hydroxylases, including the TET family of 5′-methylcytosine hydroxylases3–7.”

    From Insulator dysfunction and oncogene activation in IDH mutant gliomas (2016) · cites this paper as [4]

    The Results section (page unavailable) identifies TET enzymes as iron-dependent 5-methylcytosine hydroxylases and shows that mutant IDH inhibits TET2-mediated hydroxylation. The paper proposes 2-HG as the mechanism, but does not establish interference with the TET family as a whole or with other iron-dependent hydroxylases; the Discussion treats effects on other enzyme families as a possibility for future study. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Increased levels of 2-HG may enable a switch to an entirely HIF-independent mechanism.

    “Therefore, it is plausible that increased levels of 2-HG may enable a switch to an entirely HIF-independent mechanism.”

    From HIF-1-Independent Mechanisms Regulating Metabolic Adaptation in Hypoxic Cancer Cells (2021) · cites this paper as [153]

    The Introduction proposes that increased 2-HG may interfere with αKG-dependent enzymes such as TET2, and the Results report inhibition of TET2-associated DNA demethylation. These passages support a possible alternative mechanism, but the paper does not describe a switch from a HIF-dependent mechanism or establish that the mechanism is entirely HIF-independent (searched for HIF). Page numbers were not available in our copy. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • TET2-mutant immature and myeloid cells present with hypermethylation of active enhancers and perturbed TF activity.

    “Consistently, TET2-mutant immature and myeloid cells present with hypermethylation of active enhancers and perturbed TF activity (28, 32, 53).”

    From PU.1-Dependent Enhancer Inhibition Separates <i>Tet2</i> -Deficient Hematopoiesis from Malignant Transformation (2022) · cites this paper as [53]

    The Results section on TET2-mutant AMLs reports promoter hypermethylation, supporting the general hypermethylation finding, but it does not identify active enhancers as the affected sites. The Results discussion of transcription-factor binding sites suggests perturbed transcription-factor function in IDH1/2-mutant AMLs, not specifically in TET2-mutant cells. Page numbers are not available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Mutant IDH protein generates the oncometabolite 2-hydroxyglutarate.

    “Mutant IDH protein produces a novel onco-metabolite, 2-hydroxyglutarate (2-HG), that interferes with iron-dependent hydroxylases, including the TET family of 5′-methylcytosine hydroxylases3–7.”
  • D-2HG accumulation in cancer cells expressing mutant IDH results in hypermethylation of histones and CpG islands in DNA.

    “As a result, D-2HG accumulation in cancer cells expressing mutant IDH results in hypermethylation of histones and CpG islands in DNA (Figueroa et al., 2010; Lu et al., 2012; Turcan et al., 2012).”

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.
