Abstract

Sirt1 is the most prominent and extensively studied member of sirtuins, the family of mammalian class III histone deacetylases heavily implicated in health span and longevity. Although primarily a nuclear protein, Sirt1's deacetylation of Peroxisome proliferator-activated receptor Gamma Coactivator-1α (PGC-1α) has been extensively implicated in metabolic control and mitochondrial biogenesis, which was proposed to partially underlie Sirt1's role in caloric restriction and impacts on longevity. The notion of Sirt1's regulation of PGC-1α activity and its role in mitochondrial biogenesis has, however, been controversial. Interestingly, Sirt1 also appears to be important for the turnover of defective mitochondria by mitophagy. I discuss here evidences for Sirt1's regulation of mitochondrial biogenesis and turnover, in relation to PGC-1α deacetylation and various aspects of cellular physiology and disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • UC-MSC-CM ameliorates liver dysfunction and reduces lipid accumulation, pro-inflammatory cytokine levels and apoptotic markers in a mouse model of NAFLD.

    “Likewise, UC-MSC-CM ameliorated liver dysfunction and reduced lipid accumulation, pro-inflammatory cytokine levels and the presence of apoptotic markers in a mice model of NAFLD [196], [197].”

    From Mesenchymal stem cell secretome for regenerative medicine: Where do we stand? (2025) · cites this paper as [196]

    The retrieved passages from the References section concern SIRT1, mitochondrial function and other cell models; they do not report treatment with UC-MSC-CM in a mouse model of NAFLD. Searches for NAFLD and umbilical-cord mesenchymal stem-cell conditioned medium found no passage addressing the claimed liver, lipid, cytokine or apoptosis outcomes. (LLM, conf=0.78)

  • PGC1α can be stimulated by the AMPK/SIRT1 pathway.

    “as the main regulator of mitochondrial biogenesis, PGC1α can be stimulated by the AMPK/SIRT1 pathway [28].”

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.
