Sirtuins are a family of proteins that regulate cellular health. Sirtuins play a key role in regulating cellular homeostasis. Homeostasis involves keeping the cell in balance. However, sirtuins can only function in the presence of NAD+, nicotinamide adenine dinucleotide, a coenzyme found in all living cells.
Then, what do sirtuins have to do with aging?
However, age-related decrease in the ability to repair DNA, causes increased damage accumulation and, in consequence, cell senescence. Sirtuins are indispensable for DNA repair, controlling inflammation and antioxidative defense which makes them good anti-senescence/anti-ageing targets.

Does fasting activate sirtuins?
Sirtuins, particularly SIRT1 and SIRT3, can be activated by fasting and further exhibit their effects in insulin response, antioxidant defense, and glycolysis.
How many sirtuins are there?
In mammals, there are seven sirtuins, named SIRT1 to SIRT7. They are involved in a much broader range of cellular processes and pathways with distinct cellular localization and molecular targets (Table 1).
Does resveratrol activate sirtuin?
Moreover, resveratrol can activate the activities of sirtuins including surtuin-1 (SIRT1)18, 19. Resveratrol activates SIRT1 activation in a substrate sequence-dependent manner via deacetylation of a SF38-K23 peptide20. Resveratrol has also been shown to inhibit chondrosarcoma cell growth and induce apoptosis21, 22.
