Abstract

Alterations in the architecture and dynamics of the nuclear lamina have a causal role in normal and accelerated aging through both cell-autonomous and systemic mechanisms. However, the precise nature of the molecular cues involved in this process remains incompletely defined. Here we report that the accumulation of prelamin A isoforms at the nuclear lamina triggers an ATM- and NEMO-dependent signaling pathway that leads to NF-κB activation and secretion of high levels of proinflammatory cytokines in two different mouse models of accelerated aging (Zmpste24−/− and Lmna G609G/G609G mice). Causal involvement of NF-κB in accelerated aging was demonstrated by the fact that both genetic and pharmacological inhibition of NF-κB signaling prevents age-associated features in these animal models, significantly extending their longevity. Our findings provide in vivo proof of principle for the feasibility of pharmacological modulation of the NF-κB pathway to slow down the progression of physiological and pathological aging.

  • In mouse models of accelerated ageing, inflammation is exacerbated by overactivation of NF-κB, and blocking this pathway confers longevity.

    “In mouse models of accelerated ageing, inflammation is exacerbated by the overactivation of NF-κB, thereby blocking this pathway and consequently conferring longevity.475”
  • Inhibition of NF-κB signalling both genetically and pharmacologically prevents age-related deterioration in progeroid mouse models.

    “Inhibition of NF-κB signalling (the main transcription factor regulating the SASP) both genetically and pharmacologically, has been shown to prevent age-related deterioration in progeroid mouse models (Osorio et al., 2012).”

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.
