Abstract

Aging is referred to progressive dysfunction of body organs, including the brain. This study aims to explore the anti-aging effect of combing nicotinamide mononucleotide (NMN) and lycopene (Lyco) (NMN + Lyco) on aging rats and senescent PC12 cells. Both in vivo and in vitro aging models were established using D-galactose (D-gal). The combination showed a trend to superiority over monotherapy in preventing aging in vivo and in vitro. Morris water maze test showed that NMN + Lyco effectively improved the ability of spatial location learning and memory of aging model rats. NMN + Lyco mitigated the oxidative stress of rat brains, livers, and PC12 cells by elevating the levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), GSH, as well as total antioxidant capacity (T-AOC), and reducing malondialdehyde (MDA) content. CCK-8 assay, senescence-associated β-galactosidase staining, and flow cytometer confirmed the cellular senescence of PC12 cells after exposing D-gal, and indicated the anti-senescence effect of NMN + Lyco in vitro. Moreover, NMN + Lyco effectively down-regulated the expressions of p53, p21, and p16 (senescence-related genes), and activated Keap1-Nrf2 signaling in both in vivo and in vitro aging models. In total, NMN + Lyco protected rats and PC12 cells from cognitive impairment and cellular senescence induced by D-gal, of which effects might be linked to the reduction of oxidative stress and the activation of Keap1-Nrf2 signaling.

Claims other papers make about this one

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

  • The combination of lycopene with nicotinamide mononucleotide (NMN) is effective in reducing OS both in vitro and in vivo by enhancing the activity of SOD, CAT, GPx enzymes.

    “Moreover, the combination of lycopene with the anti-aging compound nicotinamide mononucleotide (NMN) has proven effective in reducing OS both in vitro and in vivo by enhancing the activity of SOD, CAT, GPx enzymes [175].”
  • The effect of lycopene with NMN, combined with activation of the Kaep1-Nrf2 antioxidant pathway, efficiently prevents cells to become senescent.

    “This effect, combined with the activation of the Kaep1-Nrf2 antioxidant pathway, efficiently prevents cells to become senescent, therefore confirming the promising role of lycopene in improving the anti-aging effect of already established compounds [175].”

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.
