Resurrection of endogenous retroviruses during aging reinforces senescence
Open accessPublished version of a preprint
Abstract
SUMMARY Whether and how certain transposable elements with viral origins, such as endogenous retroviruses (ERVs) dormant in our genomes, can become awakened and contribute to the aging process are largely unknown. In human senescent cells, we found that HERVK (HML-2), the most recently integrated human ERVs, are unlocked to transcribe viral genes and produce retrovirus-like particles (RVLPs). These HERVK RVLPs constitute a transmissible message to elicit senescence phenotypes in young cells, which can be blocked by neutralizing antibodies. Activation of ERVs was also observed in organs of aged primates and mice, as well as in human tissues and serum from the elderly. Their repression alleviates cellular senescence and tissue degeneration and, to some extent, organismal aging. These findings indicate that the resurrection of ERVs is a hallmark and driving force of cellular senescence and tissue aging. In brief Liu and colleagues uncover the ways in which de-repression of human endogenous retrovirus triggers cellular senescence and tissue aging; the findings provide fresh insights into therapeutic strategies for alleviating aging. Highlights Derepression of the endogenous retrovirus contributes to programmed aging Upregulation of HERVK triggers the innate immune response and cellular senescence Extracellular HERVK retrovirus-like particles induce senescence in young cells Endogenous retrovirus serves as a potential target to alleviate agings Graphical abstract

In the citing paper
“As expected, aging hallmarks such as SPiDER-βGal-positive cells, P21, 4-HNE, γH2AX-positive cells, and MMTV (a mouse homolog of human HERVK)-positive cells were found to be upregulated with advancing age across various tissues43”

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.
