Androgen receptor and growth factor signaling cross-talk in prostate cancer cells.

Abstract

Androgens promote the growth and differentiation of prostate cells through ligand activation of the androgen receptor (AR). Sensitization of the androgenic response by multifunctional growth factor signaling pathways is one of the mechanisms via which AR contributes to the emergence of androgen-independent prostate tumors. The ability of AR to cross-talk with key growth factor signaling events toward the regulation of cell cycle, apoptosis, and differentiation outcomes in prostate cancer cells is established. In this paper, we review the functional interaction between AR and an array of growth factor signal transduction events (including epidermal growth factor; fibroblast growth factor; IGF1; vascular endothelial growth factor; transforming growth factor-beta) in prostate tumors. The significance of this derailed cross-talk between androgens and key signaling networks in prostate cancer progression and its value as a therapeutic forum targeting androgen-independent metastatic prostate cancer is discussed.

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?

  • The expression of EGF and its receptor EGFR is increased in patients with advanced, aggressive prostate cancer, and both molecules have been implicated in the development and progression of many other kinds of tumors.

    “The expression of EGF and its receptor (EGFR) are increased in patients with advanced, aggressive prostate cancer, and both molecules have been implicated in the development and progression of many other kinds of tumors (33).”
  • Mitogenic growth factors such as EGF and IGF stimulate intracellular signaling that cross talks with AR signaling.

    “The ability of mitogenic growth factors such as EGF and IGF to stimulate intracellular signaling that cross talks with those of the AR has been extensively reviewed elsewhere (33).”

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.
