Telomeres and aging

Shay, Jerry W·2018·Current Opinion in Cell Biology

Abstract

Telomeres (the TTAGGG repetitive DNA at the ends of linear chromosomes) are part of the 3D spatial organization of the nuclear genome. Long-range 3D chromatin interactions also establish specific patterns of regulated gene expression. An emerging area of interest is the role of telomere 3D looping with interstitial telomeric sequences (ITS) through interactions with telomere shelterin proteins. Telomeres form interstitial telomere loops (ITL) that interact with ITS and modify gene expression at distal genomic regions. Human laminopathies and telomeropathies often correlate with short telomeres. Since telomeres progressively shorten with increased turnover and chronological age in dividing somatic cells, ITLs may also change and have functional roles in normal and pathophysiological processes. Overall, telomeres help stabilize the nuclear genome with high fidelity throughout early adult life but diminish in post-reproductive age-associated pathology.

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.
