Targeting PI3K signalling in cancer: opportunities, challenges and limitations

Engelman, Jeffrey A.·2009·Nature Reviews Cancer

Abstract

There are ample genetic and laboratory studies that suggest the PI3K-Akt pathway is vital to the growth and survival of cancer cells. Inhibitors targeting this pathway are entering the clinic at a rapid pace. In this Review, the therapeutic potential of drugs targeting PI3K-Akt signalling for the treatment of cancer is discussed. I focus on the advantages and drawbacks of different treatment strategies for targeting this pathway, the cancers that might respond best to these therapies and the challenges and limitations that confront their clinical development.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • AKT leads to activation of the mTOR1 complex.

    “AKT, through a series of complex signal transduction cascades, leads to the activation of the mTOR1 complex (Engelman, 2009).”

  • PI3K/AKT pathway alterations in HER2+ breast cancer include mutation and/or amplification of PIK3CA, PIK3CB, PIK3R1, AKT1, AKT2, PDK1, and loss of PTEN and INPP4B.

    “These include mutation and/or amplification of the genes encoding the PI3K catalytic subunits p110α (PIK3CA) and p110β (PIK3CB), the PI3K regulatory subunit p85α (PIK3R1), the PI3K effectors AKT1, AKT2, and PDK1, and loss of the lipid phosphatases PTEN and INPP4B [reviewed in (Engelman, 2009)].”
  • Somatic alterations in the PI3K/AKT pathway are the most frequent in breast cancer, occurring in approximately 30% of HER2+ tumors.

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.
