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.

, 2011 Members of the sirtuin family including the founding protein Sir2 in Saccharomyces cerevisiae have been linked to lifespan extension in simple organisms. This finding prompted evaluation of the role of Sir2 orthologues in many aging-associated conditions including neurodegeneration, type II diabetes and cancer.

It takes two to tango: NAD+ and sirtuins in aging/longevity control [PDF]
, 2016 The coupling of nicotinamide adenine dinucleotide (NAD+) breakdown and protein deacylation is a unique feature of the family of proteins called ‘sirtuins.’ This intimate connection between NAD+ and sirtuins has an ancient origin and provides a ...

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 are heavily implicated in cell cycle, cell division, transcription regulation, and metabolism ...
