    Summary
    Indeed, aged mice treated with NMN improved stress resistance against acetaminophen (APAP)-induced liver injury, indicating that NMN restored Nrf2-mediated adaptive homeostasis.

    Summary
    Further studies found that NMN increased Sirt3 activities to deacetylate age-associated acetylation at K68 and K122 in Sod2, while its effects on nuclear Nrf2 levels were diminished in Sirt3-deficient mice, suggesting that NMN-enhanced adaptive homeostasis was Sirt3-dependent.

Studies that did not test the peptide alone1

In this study, NMN (nicotinamide mononucleotide) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking NMN (nicotinamide mononucleotide).
