Telomerase beyond telomeres

Blasco, María A.·2002·Nature Reviews Cancer

Abstract

The role of telomerase in actively proliferating cells is assumed to be restricted to maintaining of telomeres above a minimum-length threshold, thereby preventing telomere exhaustion and chromosomal instability. However, forced telomerase expression in cells and mice with normal-length telomeres has shown that telomerase promotes growth and survival in a manner that is uncoupled from net telomere lengthening. These findings imply that telomerase might have a fundamental role in tumour growth and survival, even at stages when telomeres are sufficiently long.

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?

  • The molecular basis for the Hayflick Limit is erosion of telomeres that occurs each time a cell divides.

    “It was subsequently shown that the molecular basis for the Hayflick Limit is the erosion of telomeres, repeating hexameric DNA sequences at the ends of chromosomes, that occurs each time a cell divides and has been described extensively elsewhere [9-11].”

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.
