Abstract

Summary Molecular alterations involving PI3K/AKT/mTOR pathway (including mutation, copy number, protein, or RNA) were examined across 11219 human cancers representing 32 major types. Within specific mutated genes, frequency, mutation hotspot residues, in silico predictions, and functional assays were all informative in distinguishing the subset of genetic variants more likely to have functional relevance. Multiple oncogenic pathways including PI3K/AKT/mTOR converged on similar sets of downstream transcriptional targets. In addition to mutation, structural variations and partial copy losses involving PTEN and STK11 showed evidence for having functional relevance. A substantial fraction of cancers showed high mTOR pathway activity without an associated canonical genetic or genomic alteration, including cancers harboring IDH1 or VHL mutations, suggesting multiple mechanisms for pathway activation.

  • E545K at exon 9 and H1047R at exon 20 are prevalent in cancers.

    “In particular, the occurrence of E545K at exon 9 and H1047R at exon 20 is prevalent in cancers, and these mutations can constitutively activate PI3K signaling32,33.”

    From Mechanisms of KRAS inhibitor resistance in KRAS-mutant colorectal cancer harboring Her2 amplification and aberrant KRAS localization (2025) · cites this paper as [32]

    The Results section identifies E545 and H1047 as among the most frequently mutated PIK3CA positions in cancers. Our copy does not specify that the prevalent substitutions are E545K and H1047R, or identify those positions as being in exons 9 and 20. (LLM, conf=0.86)

  • PIK3CA E545K and H1047R mutations can constitutively activate PI3K signaling.

    “In particular, the occurrence of E545K at exon 9 and H1047R at exon 20 is prevalent in cancers, and these mutations can constitutively activate PI3K signaling32,33.”

    From Mechanisms of KRAS inhibitor resistance in KRAS-mutant colorectal cancer harboring Her2 amplification and aberrant KRAS localization (2025) · cites this paper as [32]

    The Introduction (page unavailable) identifies E545 and H1047 as PIK3CA mutation hotspots that activate the PI3K kinase. The Results section on recurrently mutated residues (page unavailable) reports high activity for mutants at those sites, but the available text does not specify E545K or H1047R or establish that their activation is constitutive. (LLM, conf=0.82)

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.
