Reactive oxygen species in cancer cells: Live by the sword, die by the sword

Open access
Schumacker, Paul T.·2006·Cancer Cell

Abstract

Reactive oxygen species and tumor biology are intertwined in a complex web, making it difficult to understand which came first, whether oxidants are required for tumor cell growth, and whether oxidant stress can be exploited therapeutically. Evidence suggests that transformed cells use ROS signals to drive proliferation and other events required for tumor progression. This confers a state of increased basal oxidative stress, making them vulnerable to chemotherapeutic agents that further augment ROS generation or that weaken antioxidant defenses of the cell. In this respect, it appears that tumor cells may die by the same systems they require.

Statistics

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

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Some chemotherapeutic drugs require oxygen to generate oxygen free radicals, which in turn induce cytotoxicity and promote the effect of antitumor drugs.

    “It is generally believed that some chemotherapeutic drugs require oxygen to generate oxygen free radicals, which in turn induce cytotoxicity and promote the effect of antitumor drugs. 384”

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.
