Abstract

An iron efflux pump is a pivotal protein in breast cancer biology and a strong and independent predictor of breast cancer prognosis.

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

  • Both p53 and FOXO control a distinct set of genes that are not targets of Nrf2, even though all three factors induce HMOX1 expression and Fe(II) storage and secretion, which plays a role in breast tumorigenesis, highlighting the role of antioxidants in cancer promotion.

    “Interestingly, both p53 and FOXO control a distinct set of genes that are not targets of Nrf2 activity, even though all three factors induce HMOX1 expression and, therefore, Fe(II) storage and secretion, that plays a role in breast tumorigenesis, highlighting the role of antioxidants in cancer promotion28.”

  • Cancer cells have increased expression of transferrin receptor-1, a higher rate of iron uptake from transferrin, and decreased expression of iron exporters.

    “Thus, cancer cells have increased expression of transferrin receptor-1 and a higher rate of iron uptake from transferrin [55, 56], as well as decreased expression of iron exporters [57].”
  • Higher concentrations of free iron in breast cancer cells are associated with a more aggressive tumor phenotype.

    “Interestingly, higher concentrations of free iron in breast cancer cells are associated with a more aggressive tumor phenotype [57].”
  • In invasive tumor areas, iron export via FPN is lower compared to normal tissue.

    “In invasive tumor areas, iron export via FPN is lower compared to normal tissue, with the notion that FPN expression in carcinomas inversely correlated with patient survival and disease outcome [42].”
  • FPN expression in carcinomas inversely correlated with patient survival and disease outcome.

    “In invasive tumor areas, iron export via FPN is lower compared to normal tissue, with the notion that FPN expression in carcinomas inversely correlated with patient survival and disease outcome [42].”

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.
