Sirtuins, Metabolism and Cancer [PDF]
Frontiers in Pharmacology, 2012 More than a decade ago, sirtuins were discovered as a highly conserved family of NAD+-dependent enzymes that extend lifespan in lower organisms. In mammals, sirtuins are key regulators of stress responses and metabolism, influencing a range of diseases ...

Sirtuins and Insulin Resistance [PDF]
Frontiers in Endocrinology, 2018 The mammalian Sirtuins (SIRT1-7) are an evolutionarily conserved family of NAD+-dependent deacylase and mono-ADP-ribosyltransferase. Sirtuins display distinct subcellular localizations and functions and are involved in cell survival, senescence ...

Sirtuins, Bioageing, and Cancer [PDF]
Journal of Aging Research, 2011 The Sirtuins are a family of orthologues of yeast Sir2 found in a wide range of organisms from bacteria to man. They display a high degree of conservation between species, in both sequence and function, indicative of their key biochemical roles. Sirtuins

Mitochondrial Sirtuins in Reproduction [PDF]
Antioxidants, 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 1 and Sirtuin 3 in Granulosa Cell Tumors [PDF]
International Journal of Molecular Sciences, 2021 Sirtuins (SIRTs) are NAD+-dependent deacetylases that regulate proliferation and cell death. In the human ovary, granulosa cells express sirtuin 1 (SIRT1), which has also been detected in human tumors derived from granulosa cells, i.e., granulosa cell tumors (GCTs), and in KGN cells.

Journal of Cell Science, 2011 Sirtuins are NAD-dependent deacetylases that are highly conserved from bacteria to human and SIR2 was originally shown to extend lifespan in budding yeast ([Imai et al., 2000][1]; [Kaeberlein et al., 1999][2]).

Sirtuins as a potential molecular target of cosmetic ingredients [PDF]
Farmacja Polska, 2022 Sirtuins are a group of enzymes belonging to histone deacetylases. However, they can also catalyze other deacylation reactions (including, for example, demallonylation, desuccinylation or deglutarylation), as well as ADP-ribosylation reactions.

Sirtuins: To Be or Not To Be in Diabetic Cardiomyopathy
Trends in Molecular Medicine, 2021 Diabetic cardiomyopathy is the leading cause of death among people with diabetes. Despite its severity and poor prognosis, there are currently no approved specific drugs to prevent or even treat diabetic cardiomyopathy. There is a need to understand the pathogenic mechanisms underlying the development of diabetic cardiomyopathy to design new ...

Alterations of sirtuins in mitochondrial cytochrome c-oxidase deficiency. [PDF]
PLoS ONE, 2017 Sirtuins are NAD+ dependent deacetylases, which regulate mitochondrial energy metabolism as well as cellular response to stress. The NAD/NADH-system plays a crucial role in oxidative phosphorylation linking sirtuins and the mitochondrial respiratory ...
