Abstract

Summary: We show that the antidiabetic drug metformin inhibits the expression of genes coding for multiple inflammatory cytokines seen during cellular senescence. Conditioned medium (CM) from senescent cells stimulates the growth of prostate cancer cells but treatment of senescent cells with metformin inhibited this effect. Bioinformatic analysis of genes downregulated by metformin suggests that the drug blocks the activity of the transcription factor NF‐κ B. In agreement, metformin prevented the translocation of NF‐κ B to the nucleus and inhibited the phosphorylation of I κ B and IKK α/β, events required for activation of the NF‐κ B pathway. These effects were not dependent on AMPK activation or on the context of cellular senescence, as metformin inhibited the NF‐κ B pathway stimulated by lipopolysaccharide (LPS) in ampk null fibroblasts and in macrophages. Taken together, our results provide a novel mechanism for the antiaging and antineoplastic effects of metformin reported in animal models and in diabetic patients taking this drug.

  • SASP inhibitors can directly or indirectly attenuate the SASP by inhibiting NF-κB, JAK-STAT, mTOR, mitochondrial complex-1-related or 4-related targets, or other pathways involved in SASP induction and maintenance.

    “SASP inhibitors (senomorphics) can directly or indirectly attenuate the SASP of senescent cells by inhibiting transcription factor nuclear factor (NF)-κB, the JAK-STAT signal transduction pathway, the serine/threonine protein kinase mTOR, mitochondrial complex-1-related or 4-related targets, or other pathways involved in the induction and maintenance of the SASP103–106.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [106]

    The Discussion reports that metformin reduces inflammatory cytokine production in senescent cells by interfering with NF-κB, and the Effects of metformin on the NF-κB pathway section reports inhibition of IKK activation. The paper does not establish SASP attenuation through JAK-STAT, mTOR, or mitochondrial complex-1- or complex-4-related targets, so it supports only part of the cited list. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The pro-inflammatory cytokine network is one potential anti-aging target, using anti-inflammation drugs such as metformin, aspirin, rapamycin, and ibuprofen.

    “Recent studies have demonstrated that the pro-inflammatory cytokine network is one potential anti-aging target, using anti-inflammation drugs such as metformin, aspirin, rapamycin, and ibuprofen.”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [337]

    The Discussion reports that metformin reduces pro-inflammatory cytokine production in senescent cells through NF-κB inhibition, supporting the cytokine network as a potential anti-aging target. The paper does not establish aspirin, rapamycin, or ibuprofen as drugs acting on that target, so it supports only the metformin example. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Metformin can reduce chronic inflammation and improve healthy mid-life aging by acting on targets such as IKK/NF-κB in patients with Type 2 diabetes, as well as GPX7/NRF2 and PEN2.

    “For example, metformin can reduce chronic inflammation and improve healthy mid-life aging by acting on possible targets such as IKK/NF-κB in patients with Type 2 diabetes,337 as well as GPX7/NRF2338 and a recently found target, PEN2.339”

    From Inflammation and aging: signaling pathways and intervention therapies (2023) · cites this paper as [337]

    The Abstract and Discussion report that metformin suppresses inflammatory cytokines by interfering with IKK/NF-κB signaling. The experiments described are in cells; the Discussion cites reduced cytokines in patients with impaired fasting glucose, but does not establish this mechanism or improved healthy mid-life aging in patients with Type 2 diabetes. GPX7/NRF2 and PEN2 have separate citations in the citing sentence and are not judged here. Page numbers are unavailable in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Metformin prevents nuclear translocation of NF-κB pathway components and their subsequent transactivation at target gene promoters, thereby reducing expression of various SASP factors and potentially explaining, at least in part, the anti-ageing and antitumour effects of metformin in both mouse models and patients with diabetes.

    “Metformin, to some extent, prevents nuclear translocation of NF-κB pathway components and their subsequent transactivation at target gene promoters, thereby reducing expression of various SASP factors and potentially explaining, at least in part, the anti-ageing and antitumour effects of metformin in both mouse models and patients with diabetes 219 .”

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.
