Comparative biology of mammalian telomeres: hypotheses on ancestral states and the roles of telomeres in longevity determination
Open accessAbstract
Summary: Progressive telomere shortening from cell division (replicative aging) provides a barrier for human tumor progression. This program is not conserved in laboratory mice, which have longer telomeres and constitutive telomerase. Wild species that do/do not use replicative aging have been reported, but the evolution of different phenotypes and a conceptual framework for understanding their uses of telomeres is lacking. We examined telomeres/telomerase in cultured cells from > 60 mammalian species to place different uses of telomeres in a broad mammalian context. Phylogeny‐based statistical analysis reconstructed ancestral states. Our analysis suggested that the ancestral mammalian phenotype included short telomeres (< 20 kb, as we now see in humans) and repressed telomerase. We argue that the repressed telomerase was a response to a higher mutation load brought on by the evolution of homeothermy. With telomerase repressed, we then see the evolution of replicative aging. Telomere length inversely correlated with lifespan, while telomerase expression co‐evolved with body size. Multiple independent times smaller, shorter‐lived species changed to having longer telomeres and expressing telomerase. Trade‐offs involving reducing the energetic/cellular costs of specific oxidative protection mechanisms (needed to protect < 20 kb telomeres in the absence of telomerase) could explain this abandonment of replicative aging. These observations provide a conceptual framework for understanding different uses of telomeres in mammals, support a role for human‐like telomeres in allowing longer lifespans to evolve, demonstrate the need to include telomere length in the analysis of comparative studies of oxidative protection in the biology of aging, and identify which mammals can be used as appropriate model organisms for the study of the role of telomeres in human cancer and aging.

In the citing paper
“The programmed silencing of TERT, loss of telomerase activity and the resulting shortening of telomeres is not a universal phenomenon in mammals. Apparently, this tumour suppressor pathway is restricted to large animals with a reproductive strategy that requires a long lifespan28.”
From Telomeres in cancer: tumour suppression and genome instability (2017) · cites this paper as [28]
In the citing paper
“Taken together, it seems that the evolution of large body sizes and longevity is strongly associated with the evolution of short telomeres and telomerase suppression, presumably for tumour suppression (de Magalhaes, 2013; Gomes et al., 2011).”

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.
