referenceDNA damage responses and p53 are involved in the aging process, as reviewed by Ou and Schumacher in a 2018 article in Blood.
claimIn telomere-dysfunctional animals, administration of nicotinamide mononucleotide (NMN) preserves telomere length, inhibits the DNA damage response and p53, enhances mitochondrial activity, and reverses liver fibrosis.
claimThe DNA repair response in stem cells declines with ageing, leading to the loss of stem cell properties, DNA damage-caused cellular senescence, and organ atrophy.
