Abstract

Accumulation of mutations and chromosomal aberrations is one of the hallmarks of cancer cells. This enhanced genetic instability is fueled by defects in the genome maintenance mechanisms including DNA repair and cell cycle checkpoint pathways. Here, we discuss the emerging roles of the mammalian Chk1 and Chk2 kinases as key signal transducers within the complex network of genome integrity checkpoints, as candidate tumor suppressors disrupted in sporadic as well as some hereditary malignancies and as potential targets of new anticancer therapies.

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?

  • In budding yeast, Mec1 activates Rad53 and Chk1; in human cells, ATM activates Chk2 and ATR activates Chk1.

    “In budding yeast, Mec1 activates both Rad53 and Chk1 [26], while in human cells Chk2 is activated by ATM and Chk1 by ATR [27].”

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.
