Mitochondrial Sirtuins in Reproduction [PDF]

open access: yesAntioxidants, 2021
Mitochondria act as hubs of numerous metabolic pathways. Mitochondrial dysfunctions contribute to altering the redox balance and predispose to aging and metabolic alterations. The sirtuin family is composed of seven members and three of them, SIRT3-5, are housed in mitochondria.

Sirtuin inhibitors

Expert Opinion on Therapeutic Patents, 2009
The sirtuin family of deacetylase enzymes comprises seven proteins (SIRT1-7) that are dependent on NAD(+) for their activity. Three proteins are located in the nucleus, three in the mitochondria and only one is predominantly cytoplasmic. Caloric restriction and oxidative stress generally up-regulate their expression. SIRT1, the orthologue of yeast Sir2,

The Biochemistry of Sirtuins

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.

Sirtuins and Renal Oxidative Stress

open access: yesAntioxidants, 2021
Renal failure is a major health problem that is increasing worldwide. To improve clinical outcomes, we need to understand the basic mechanisms of kidney disease. Aging is a risk factor for the development and progression of kidney disease.

Mitochondrial sirtuins

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2010
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.

Sirtuin activators

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 ...

Flavonoids as Sirtuin Modulators

Current Topics in Medicinal Chemistry, 2022
Abstract: 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.

The Many Faces of Sirtuins: Sirtuins and the Warburg effect

Nature Medicine, 2014
Metabolic regulators that permit adaptation to changes in caloric intake have been shown to be needed to protect from age-related disorders. Sirtuins play a crucial part in this program, impinging on not only aging but also other diseases. New findings are uncovering the multifaceted activity of sirtuins in living organisms and their effects on ...
