Nettet14. sep. 2024 · The lifespan extending abilities of the sirtuins were first discovered in yeast in the 1990s 1,2 when the silent information regulator (SIR2) gene was shown to increase the replicative lifespan of yeast when upregulated. 2 Sir2 is a yeast gene silencing protein, which silences transcription at the HM mating-type loci in young yeast but … Nettet22. jun. 2024 · A preferred general strategy for activation of sirtuins (Fig. 1) would be to increase their sensitivity to NAD+through a reduction of Km,NAD+. Km,NAD+reduction would have a similar activating effect to NAD+supplementation, but would be selective for sirtuins and could potentially even provide isoform specific sirtuin activation.
