Role of sirtuins in lifespan regulation is linked to methylation of nicotinamide
Open accessAbstract
Sirtuins, a family of histone deacetylases, have a fiercely debated role in regulating lifespan. In contrast with recent observations, here we find that overexpression of sir-2.1, the ortholog of mammalian SirT1, does extend Caenorhabditis elegans lifespan. Sirtuins mandatorily convert NAD(+) into nicotinamide (NAM). We here find that NAM and its metabolite, 1-methylnicotinamide (MNA), extend C. elegans lifespan, even in the absence of sir-2.1. We identify a previously unknown C. elegans nicotinamide-N-methyltransferase, encoded by a gene now named anmt-1, to generate MNA from NAM. Disruption and overexpression of anmt-1 have opposing effects on lifespan independent of sirtuins, with loss of anmt-1 fully inhibiting sir-2.1-mediated lifespan extension. MNA serves as a substrate for a newly identified aldehyde oxidase, GAD-3, to generate hydrogen peroxide, which acts as a mitohormetic reactive oxygen species signal to promote C. elegans longevity. Taken together, sirtuin-mediated lifespan extension depends on methylation of NAM, providing an unexpected mechanistic role for sirtuins beyond histone deacetylation.

In the citing paper
“a supraphysiologic dose of NAM (1–5 mM as compared with 200 μM used in experiments with lifespan extension190) has also been associated with reduced lifespan in yeast and C. elegans190–192.”
From NAD+ metabolism and its roles in cellular processes during ageing (2021) · cites this paper as [191]
In the citing paper
“As NAD+ supplementation also results in potentially beneficial production of N-methylnicotinamide via sirtuins ((Schmeisser et al. 2013)), evidence such as the link to MnSOD affirms roles for acylation both as a direct effector modulated by NAD+ and in transducing NAD+ into an N-methylnicotinamide signal.”

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.
