Hypervariable ultra-long telomeres in mice

Kipling, David, Cooke, Howard J.·1990·Nature

Abstract

Telomere structure and behaviour is less well understood in vertebrates than it is in ciliates and yeasts (reviewed in ref. 1). Like all other eukaryotic chromosomes, those of vertebrates terminate in an array of a short repeated sequence. In vertebrates this sequence is (TTAGGG)n, as shown by in situ hybridization. In humans, these terminal repeats are heterogeneous in length, averaging about 10 kilobases in blood cells. Here we report the structure and inheritance of the terminal repeats present at mouse telomeres. The (TTAGGG)n tracts are many times larger than those present at human telomeres. Because of their constancy in length through somatic cell divisions, they are resolved as multiple discrete restriction fragments of up to 150 kilobases. Strikingly, this banding pattern is highly polymorphic within populations of inbred mice, suggesting an unusually high mutation rate. Indeed, although the banding pattern is inherited in a largely mendelian fashion, (TTAGGG)n tracts of new size appear frequently in family studies.

Statistics

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?

  • Humans have relatively short telomeres of about 5-15 kilobases, whereas inbred laboratory mice typically have telomeres longer than 40 kilobases.

    “Humans have relatively short telomeres of ~5–15 kilobases in comparison to inbred strains of laboratory mice which have telomeres that are typically >40 kilobases (Kipling and Cooke, 1990).”

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.
