Sirtuins are involved in numerous biological processes such as cell survival and metabolism, aging, and DNA repair; thus they modulate crucial metabolic pathways. The seven members of the Sirtuin family are more and more seen as potential targets for the treatment of cancer, metabolic, neurodegenerative, and cardiovascular diseases.

Sirtuins have emerged as important proteins in aging, stress resistance and metabolic regulation. Three sirtuins, SIRT3, 4 and 5, are located within the mitochondrial matrix. SIRT3 and SIRT5 are NAD(+)-dependent deacetylases that remove acetyl groups from acetyllysine-modified proteins and yield 2'-O-acetyl-ADP-ribose and nicotinamide.

Expert Opinion on Therapeutic Patents, 2009
Sirtuin 1-7 (SIRT1-7) are deacetylases that are dependent on NAD(+) for their activity. SIRT1 down-regulates p53 activity, increasing lifespan, cell survival, and neuroprotection; it also deacetylates peroxisome proliferator-activated receptor-gamma and its coactivator 1alpha, promoting fat mobilization, increasing mitochondrial size and number, and ...

The nematode Caenorhabditis elegans (C. elegans) has four Sir2 paralogs, sir-2.1, sir-2.2, sir-2.3, and sir-2.4. Thus far, most of the research tools to study worm sirtuins have been developed for sir-2.1, due to its homology to yeast SIR2 and human SIRT1.

Flavonoids as Sirtuin Modulators
Current Topics in Medicinal Chemistry, 2022Abstract: Sirtuins (SIRTs) are described as NAD+-dependent deacetylases, also known as class III histone deacetylases. So far, seven sirtuin genes (SIRTS 1–7) have been identified and characterized in mammals and also known to occur in bacteria and eukaryotes.

Epigenetics, sirtuins and osteoarthritis
Joint Bone Spine, 2012Epigenetics, modifications of the DNA other than changes on the DNA sequences, is frequently studied in cancer research and aging. DNA methylation, mi-RNA, and histones deacetylation are investigated in different pathologies, including inflammatory diseases and age-related diseases such as osteoarthritis (OA).

Sirtuins are a family of NAD+-dependent protein deacetylases widely distributed in all phyla of life. Accumulating evidence indicates that sirtuins are important regulators of organism life span. In yeast, these unique enzymes regulate gene silencing by histone deacetylation and via formation of the novel compound 2′-O-acetyl-ADP-ribose.

Resveratrol, sirtuins, and viruses
Reviews in Medical Virology, 2015SummaryResveratrol is a natural phenolic product found in some plants in response to stress and has been linked to the many health benefits of red wine. Over the past several decades, a great deal of research has identified diverse biological roles associated with resveratrol, including anti‐oxidant, anti‐proliferation, anti‐inflammation, anti‐cancer ...

The sirtuin family of intracellular enzymes are able to catalyze a unique β-nicotinamide adenine dinucleotide (β-NAD+)-dependent Nε-acyl-lysine deacylation reaction on histone and non-histone protein substrates. Since 2000, the sirtuin family members have been identified in both prokaryotes and eukaryotes; tremendous accomplishments have also been ...
