Abstract

The mouse-sized naked mole rat (Heterocephalus glaber) is a very unusual mammal. It is a social animal, living in groups in burrows beneath arid African deserts. It can live for 30 or more years in atmospheres with low oxygen and high carbon dioxide, and is remarkably resistant to cancer. So the genome sequence, published in this issue, might be expected to contain some intriguing characteristics. Analysis of the genome and its transcriptome reveals unusual genomic features and molecular adaptations including strategies for improved genome stability, low mutation rate and improved protein maintenance. The data also reveal molecular adaptations consistent with poor visual function, poikilothermy, hairlessness, circadian rhythms, taste sensing and insensitivity to low oxygen. The naked mole rat (Heterocephalus glaber) is a strictly subterranean, extraordinarily long-lived eusocial mammal1. Although it is the size of a mouse, its maximum lifespan exceeds 30 years, making this animal the longest-living rodent. Naked mole rats show negligible senescence, no age-related increase in mortality, and high fecundity until death2. In addition to delayed ageing, they are resistant to both spontaneous cancer and experimentally induced tumorigenesis3,4. Naked mole rats pose a challenge to the theories that link ageing, cancer and redox homeostasis. Although characterized by significant oxidative stress5, the naked mole rat proteome does not show age-related susceptibility to oxidative damage or increased ubiquitination6. Naked mole rats naturally reside in large colonies with a single breeding female, the ‘queen’, who suppresses the sexual maturity of her subordinates7. They also live in full darkness, at low oxygen and high carbon dioxide concentrations8, and are unable to sustain thermogenesis9 nor feel certain types of pain10,11. Here we report the sequencing and analysis of the naked mole rat genome, which reveals unique genome features and molecular adaptations consistent with cancer resistance, poikilothermy, hairlessness and insensitivity to low oxygen, and altered visual function, circadian rythms and taste sensing. This information provides insights into the naked mole rat’s exceptional longevity and ability to live in hostile conditions, in the dark and at low oxygen. The extreme traits of the naked mole rat, together with the reported genome and transcriptome information, offer opportunities for understanding ageing and advancing other areas of biological and biomedical research.

  • The genome of the longest-lived rodent, the naked mole rat, contains fewer retrotransposons than other rodent genomes.

    “Interestingly, the genome of the longest-lived rodent, the naked mole rat, contains fewer retrotransposons than other rodent genomes108; whereas the genomes of long-lived bats are replete with transposable elements109.”

    From The role of retrotransposable elements in ageing and age-associated diseases (2021) · cites this paper as [108]

    The genome-sequencing passage (labeled Abstract; page unavailable) reports that transposon-derived repeats occupy about 25% of the naked mole-rat genome, versus 37% in mouse and 35% in rat. The paper also calls the naked mole rat the longest-living rodent. It does not separately establish the claimed comparison for retrotransposons, a more specific category. (LLM, conf=0.83)

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.
