Abstract

Cellular senescence is a stable growth arrest that is implicated in tissue ageing and cancer. Senescent cells are characterized by an upregulation of proinflammatory cytokines, which is termed the senescence-associated secretory phenotype (SASP). NAD+ metabolism influences both tissue ageing and cancer. However, the role of NAD+ metabolism in regulating the SASP is poorly understood. Here, we show that nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme of the NAD+ salvage pathway, governs the proinflammatory SASP independent of senescence-associated growth arrest. NAMPT expression is regulated by high mobility group A (HMGA) proteins during senescence. The HMGA-NAMPT-NAD+ signalling axis promotes the proinflammatory SASP by enhancing glycolysis and mitochondrial respiration. HMGA proteins and NAMPT promote the proinflammatory SASP through NAD+-mediated suppression of AMPK kinase, which suppresses the p53-mediated inhibition of p38 MAPK to enhance NF-κB activity. We conclude that NAD+ metabolism governs the proinflammatory SASP. Given the tumour-promoting effects of the proinflammatory SASP, our results suggest that anti-ageing dietary NAD+ augmentation should be administered with precision.

  • The nutrient sensing pathways mTOR and NAD are involved in SASP regulation.

    “In addition, the nutrient sensing pathways, mTOR and NAD, are involved in SASP regulation.56, 57, 58”

    From Cellular senescence and senescence-associated secretory phenotype via the cGAS-STING signaling pathway in cancer (2020) · cites this paper as [58]

    The Results section, “NAD+ metabolism governs the strengths of the proinflammatory SASP” (page unavailable), reports that an increased NAD+/NADH ratio enhances the proinflammatory SASP. The cited paper therefore supports the NAD part of the sentence, but the passages retrieved for mTOR do not establish its role in SASP regulation. (LLM, conf=0.86)

  • FK866, a specific NAMPT inhibitor, suppresses the proinflammatory SASP and limits pancreatic ductal adenocarcinoma (PDAC) progression.

    “the use of FK866, a specific NAMPT inhibitor, suppresses the proinflammatory SASP and limits pancreatic ductal adenocarcinoma (PDAC) progression (Nacarelli et al. 2019).”

    From Senescence and the SASP: many therapeutic avenues (2020) · cites this paper as Nacarelli et al. 2019

    The Results sections “NAMPT promotes the proinflammatory SASP” and “NAD+ metabolism promotes cancer progression” identify FK866 as a NAMPT inhibitor and report that it suppresses proinflammatory SASP markers. But the pancreatic mouse-model results do not show that FK866 limits cancer progression; the authors instead say its findings suggest tumor progression associated with overcoming senescence. No page numbers are available in our copy. (LLM, conf=0.89)

  • In an oncogenic mouse model, NMN supplementation at 500 mg/kg body weight daily for 13 days significantly increased the pro-inflammatory senescence secretory phenotype and promoted pancreatic ductal adenocarcinoma progression.

    “In an oncogenic mouse model, the supplementation with NMN (500 mg/kg body weight daily for 13 days) significantly increased the secretory phenotype associated with pro-inflammatory senescence, promoting pancreatic ductal adenocarcinoma progression.”
  • NAD+/NADH metabolism is a critical regulator of the magnitude of proinflammatory SASP linked to oncogene activation, and this regulation can occur independently of senescence-induced growth arrest.

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.
