Sirtuin Pathways

Meaning

Sirtuin Pathways refer to the family of NAD+-dependent deacetylase enzymes (SIRT1-SIRT7) that play a critical, conserved role in regulating cellular health, metabolism, and stress resistance in response to energy availability. These enzymes act as crucial cellular sensors, linking the cell’s metabolic status to the regulation of gene expression, DNA repair, and mitochondrial function. Activation of these pathways is a key target in longevity and anti-aging research.
