Abstract

RAS proteins are small GTPases that regulate signalling networks that control cellular proliferation and survival. They are frequently mutated in cancer and a commonly occurring group of developmental disorders called RASopathies. We discuss recent findings describing how RAS isoforms and different activating mutations differentially contribute to normal and disease-associated biology and the mechanisms that have been proposed to underpin this.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Somatic RAS mutations are primarily gain-of-function missense alterations at codons 12, 13, or 61 that impair GTP hydrolysis to favor the active state, resulting in increased downstream signaling linked to proliferation, survival, and tumorigenesis.

    “Somatic RAS mutations were the first oncogenic mutations identified in human cancers (1) and are primarily comprised of gain-of-function missense alterations at codons 12, 13, or 61 that impair GTP hydrolysis to favor the protein's active state, resulting in increased activation of downstream signaling pathways linked to cell proliferation, cell survival, and tumorigenesis (2).”

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.
