PI3K pathway alterations in cancer: variations on a theme

Open access
Yuan, T L, Cantley, L C·2008·Oncogene

Abstract

The high frequency of phosphoinositide 3-kinase (PI3K) pathway alterations in cancer has led to a surge in the development of PI3K inhibitors. Many of these targeted therapies are currently in clinical trials and show great promise for the treatment of PI3K-addicted tumors. These recent developments call for a re-evaluation of the oncogenic mechanisms behind PI3K pathway alterations. This pathway is unique in that every major node is frequently mutated or amplified in a wide variety of solid tumors. Receptor tyrosine kinases upstream of PI3K, the p110 alpha catalytic subunit of PI3K, the downstream kinase, AKT, and the negative regulator, PTEN, are all frequently altered in cancer. In this review, we will examine the oncogenic properties of these genetic alterations to understand whether they are redundant or distinct and propose treatment strategies tailored for these genetic lesions.

  • The PI3K pathway is hyperactivated not only in GBM, but also in many other cancers including breast, ovarian, endometrial, lung, prostate, renal and lymphocyte.

    “Furthermore, the PI3K pathway is hyperactivated not only in GBM, but also in many other cancers including breast, ovarian, endometrial, lung, prostate, renal and lymphocyte (5, 56–58).”

    From An LXR Agonist Promotes Glioblastoma Cell Death through Inhibition of an EGFR/AKT/SREBP-1/LDLR–Dependent Pathway (2011) · cites this paper as [57]

    The Introduction and Known mutations in the pathway sections describe widespread PI3K-pathway dysregulation in cancer. The glioblastoma, HER2, and PTEN sections provide examples involving GBM and breast, ovarian, endometrial, lung, and prostate cancers. Our copy does not establish the claim for renal cancer or lymphocyte-derived cancer; its Immune cells section discusses PI3K activation in immune cells within the tumor environment, not cancers of those cells.

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.
