Why NAD + Declines during Aging: It’s Destroyed

Open access
Schultz, Michael B., Sinclair, David A.·2016·Cell Metabolism

Abstract

NAD(+) is required not only for life but for a long life. In this issue, Camacho-Pereira et al. (2016) implicate CD38 in the decline of NAD(+) during aging, with implications for combating age-related diseases.

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

  • Senescent cells can decrease NAD+ via SASP activation of CD38 on macrophages, and senolytics partially restore tissue NAD+ levels.

    “Senescent cells can decrease NAD+ through SASP activation of the NAD-degrading enzyme CD38 on the surface of macrophages and, remarkably, senolytics partially restore tissue NAD+ levels139,140.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [140]

    The paper’s Abstract links rising CD38 activity during aging to declining NAD+ levels and reports that mice lacking CD38 retain higher NAD+ levels. It does not describe SASP activation of CD38 on macrophages or report that senolytics restore tissue NAD+; its discussion of inflammation as a possible trigger is speculative. (LLM, conf=0.86)

  • Sirtuin activity and NAD levels both decline with age.

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.
