Isocitrate dehydrogenase 1 and 2 mutations in cancer: alterations at a crossroads of cellular metabolism

Abstract

Dysregulation of metabolism is a common phenomenon in cancer cells. The NADP(+)-dependent isocitrate dehydrogenases 1 and 2 (IDH1 and IDH2) function at a crossroads of cellular metabolism in lipid synthesis, cellular defense against oxidative stress, oxidative respiration, and oxygen-sensing signal transduction. We review the normal functions of the encoded enzymes, frequent mutations of IDH1 and IDH2 recently found in human cancers, and possible roles for the mutated enzymes in human disease. IDH1 and IDH2 mutations occur frequently in some types of World Health Organization grades 2-4 gliomas and in acute myeloid leukemias with normal karyotype. IDH1 and IDH2 mutations are remarkably specific to codons that encode conserved functionally important arginines in the active site of each enzyme. To date, all IDH1 mutations have been identified at the Arg132 codon. Mutations in IDH2 have been identified at the Arg140 codon, as well as at Arg172, which is aligned with IDH1 Arg132. IDH1 and IDH2 mutations are usually heterozygous in cancer, and they appear to confer a neomorphic enzyme activity for the enzymes to catalyze the production of D-2-hydroxyglutarate. Study of alterations in these metabolic enzymes may provide insights into the metabolism of cancer cells and uncover novel avenues for development of anticancer therapeutics.

  • Metabolic reprogramming is a hallmark of cancer based on the discovery of mutations and alterations in IDH1 and IDH2 along with SDH, FH, and PKM2.

    “There is a renewed interest in the area of cancer metabolism with metabolic reprogramming coined as a hallmark of cancer based on the discovery of mutations and alterations in IDH1 and IDH2 along with succinate dehydrogenase (SDH), fumarate hydratase (FH), and pyruvate kinase M2 (PKM2) [41, 42].”

    From Modeling APC mutagenesis and familial adenomatous polyposis using human iPS cells (2018) · cites this paper as [42]

    The opening summary (page not specified in our copy) says metabolic dysregulation is common in cancer and reports frequent IDH1 and IDH2 mutations in certain cancers. It does not establish that metabolic reprogramming was designated a cancer hallmark on the basis of the full list of enzymes. SDH and FH appear in a cited reference, while the searched passages do not substantiate the PKM2 part of the claim. (LLM, conf=0.85)

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.
