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.

Sirtuins: Multifaceted Drug Targets
Current Molecular Medicine, 2011Sirtuin (Sir2) proteins being key regulators of numerous cellular processes have been, over the recent past, the subject of intense study. Sirs have been implicated in diverse physiological processes ranging from aging and cancer to neurological dysfunctions.

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).

Annual Review of Biochemistry, 2006
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 ...

Sirtuins, epigenetics and longevity
Ageing Research Reviews, 2017Aging of organisms begins from a single cell at the molecular level. It includes changes related to telomere shortening, cell senescence and epigenetic modifications. These processes accumulate over the lifespan. Research studies show that epigenetic signaling contributes to human disease, tumorigenesis and aging.
