Abstract

The discovery of somatic mutations in the gene encoding isocitrate dehydrogenase-1 (IDH1) in glioblastomas was remarkable because the enzyme was not previously identified with any known oncogenic pathway. IDH1 is mutated in up to 75% of grade II and grade III diffuse gliomas. Apart from acute myeloid leukaemia, other tumour types do not carry IDH1 mutations. Mutations in a homologous gene, IDH2, have also been identified, although they are much rarer. Although TP53 mutations and 1p/19q codeletions are mutually exclusive in gliomas, in both of these genotypes IDH1 mutations are common. IDH1 and IDH2 mutations are early events in the development of gliomas. Moreover, IDH1 and IDH2 mutations are a major prognostic marker for overall and progression-free survival in grade II-IV gliomas. Mutated IDH1 has an altered catalytic activity that results in the accumulation of 2-hydroxyglutarate. Molecularly, IDH1 and IDH2 mutations are heterozygous, affect only a single codon, and rarely occur together. Because IDH1 does not belong to a traditional oncogenic pathway and is specifically and commonly mutated in gliomas, the altered enzymatic activity of IDH1 may provide a fundamentally new understanding of diffuse glioma.

  • IDH1 mutations are found in approximately 75% of secondary glioblastoma but are rare in primary glioblastoma.

    “One of the key molecular differences between primary and secondary glioblastoma is the presence of isocitrate dehydrogenase-1 (IDH1) mutations which are found in approximately 75% of secondary GBM but are rare in primary GBM [13].”

  • GOF mut-p53 exhibits interactions with distinct transcription factors (e.g., NF-ɣ, SREBP, VDR, Sp1, ETS2, NFR2, p73, p63) that promote tumor initiation and progression.

    “In contrast to wt-p53, GOF mut-p53 exhibits interactions with distinct transcription factors (e.g., NF-ɣ, SREBP, VDR, Sp1, ETS2, NFR2, p73, p63) that promote tumor initiation and progression [13,72,73,74,75,76,77].”

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.
