Essential role of limiting telomeres in the pathogenesis of Werner syndrome
Abstract
Mutational inactivation of the gene WRN causes Werner syndrome, an autosomal recessive disease characterized by premature aging, elevated genomic instability and increased cancer incidence. The capacity of enforced telomerase expression to rescue premature senescence of cultured cells from individuals with Werner syndrome and the lack of a disease phenotype in Wrn-deficient mice with long telomeres implicate telomere attrition in the pathogenesis of Werner syndrome. Here, we show that the varied and complex cellular phenotypes of Werner syndrome are precipitated by exhaustion of telomere reserves in mice. In late-generation mice null with respect to both Wrn and Terc (encoding the telomerase RNA component), telomere dysfunction elicits a classical Werner-like premature aging syndrome typified by premature death, hair graying, alopecia, osteoporosis, type II diabetes and cataracts. This mouse model also showed accelerated replicative senescence and accumulation of DNA-damage foci in cultured cells, as well as increased chromosomal instability and cancer, particularly nonepithelial malignancies typical of Werner syndrome. These genetic data indicate that the delayed manifestation of the complex pleiotropic of Wrn deficiency relates to telomere shortening.

“In support of this hypothesis, lack of a disease phenotype in mouse models of other human diseases, such as Werner and Ataxia-Telangiectasia syndromes, has been linked to species-specific differences in telomere length, as when these models were crossed with mice lacking telomerase activity, the disease became apparent (Chang et al., 2004; Wong et al., 2003).”

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.
