Mitochondrial sirtuins in the heart
Heart Failure Reviews, 2016Sirtuins (SIRTs) are NAD(+)-dependent enzymes that catalyze deacylation of protein lysine residues. In mammals, seven sirtuins have been identified, SIRT1-7. SIRT3-5 are mainly or exclusively localized within mitochondria and mainly participate in the regulation of energy metabolic pathways.

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.

Sirtuin activators and inhibitors [PDF]
BioFactors, 2012 AbstractSirtuins 1‐7 (SIRT1‐7) belong to the third class of deacetylase enzymes, which are dependent on NAD+ for activity. Sirtuins activity is linked to gene repression, metabolic control, apoptosis and cell survival, DNA repair, development, inflammation, neuroprotection, and healthy aging. Because sirtuins modulation could have beneficial effects on

The advancement of age is accompanied by the increased incidence of various diseases, including neurodegeneration, cancer, and metabolic diseases. At a molecular level, these diseases are associated with a plethora of pathophysiological mechanisms, including deficiency in nutrient sensing, proteostasis, and mitochondrial function.

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 ...

Sirtuins are a family of highly conserved genes widely distributed in organisms ranging from bacteria to humans. Mounting evidence has revealed the important role of sirtuins in a variety of biological processes, including transcription regulation, apoptosis, DNA repair, metabolism, and more prominently, aging.

The role of sirtuins in cancer has recently stimulated both considerable interest and debate. It is becoming clear that some sirtuins deacetylate important tumor suppressors thereby impinging on their activity. Human SirT1, for instance, has been shown to deacetylate p53 in biochemical assays, and growing evidence indicates that it also performs this ...

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 ...

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.

Sirtuins and the prevention of immunosenescence
2021Aging of hematopoietic stem cells (HSCs) has been largely described as one underlying cause of senescence of the immune-hematopoietic system (immunosenescence). A set of well-defined hallmarks characterizes aged HSCs contributing to unbalanced hematopoiesis and aging-associated functional alterations of both branches of the immune system.
