Abstract

Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase involved in the regulation of many cellular processes. A confirmed tumor suppressor protein, PP2A is genetically altered or functionally inactivated in many cancers highlighting a need for its therapeutic reactivation. In this review we discuss recent literature on PP2A: the elucidation of its structure and the functions of its subunits, and the identification of molecular lesions and post-translational modifications leading to its dysregulation in cancer. A final section will discuss the proteins and small molecules that modulate PP2A and how these might be used to target dysregulated forms of PP2A to treat cancers and other diseases.

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

  • The tumor suppressive role of specific PP2A complexes had been inferred from okadaic acid experiments, in vitro transformation assays, and clinical data, but convincing in vivo data were lacking for some time.

    “Although the tumor suppressive role of specific PP2A complexes had already been inferred for a relatively long time, from experiments with the tumor promotor and pharmacologic PP2A inhibitor okadaic acid [100], from in vitro cell transformation assays in a large variety of epithelial cells [101], and from a plethora of clinical data supporting PP2A dysfunction in many different cancer types [5,102”

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.
