Coordinated regulation of life and death by RB

Chau, B. Nelson, Wang, Jean Y.J.·2003·Nature Reviews Cancer

Abstract

Recent studies have shown that RB can inhibit apoptosis, independently of its ability to block cell proliferation. This poses the question of how cells choose to grow or to die when RB becomes inactivated. RB is phosphorylated following mitogenic stimulation, but it is degraded in response to death stimuli. Most sporadic cancers also inactivate RB by phosphorylation, rather than losing RB entirely--possibly to exploit the survival advantage conferred by RB under stress. Drawing from the different mechanisms of RB inactivation, we propose two models for ways in which cells use RB to make the choice of life versus death.

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Both p53/p21 and p16/pRB pathways are complex, involving many upstream regulators and downstream effectors along with varying side branches.

    “Both these pathways are complex as they involve many upstream regulators and downstream effectors along with varying side branches (Chau and Wang, 2003; Levine and Oren, 2009).”
  • Abnormal proliferation induced by loss of RB is often accompanied by increased cell death through p53-dependent and independent mechanisms.

    “abnormal proliferation that is induced by loss of RB is often accompanied by increased cell death, through p53-dependent and independent mechanisms49,57,87–91.”

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.
