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.

Insights regarding sirtuin-dependent gene regulation during white koji production
Communicative & Integrative Biology, 2022 White koji, a solid-state culture of Aspergillus luchuensis mut. kawachii using grains such as rice and barley, is used as a source of amylolytic enzymes and citric acid for the production of shochu, a traditional Japanese distilled spirit. We previously

Sirtuin functions and modulation: from chemistry to the clinic [PDF]
, 2016 Sirtuins are NAD+ -dependent histone deacetylases regulating important metabolic pathways in prokaryotes and eukaryotes and are involved in many biological processes such as cell survival, senescence, proliferation, apoptosis, DNA repair, cell ...

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 ...

Segmental aging underlies the development of a Parkinson phenotype in the AS/AGU rat [PDF]
, 2016 There is a paucity of information on the molecular biology of aging processes in the brain. We have used biomarkers of aging (SA β-Gal, p16Ink4a, Sirt5, Sirt6, and Sirt7) to demonstrate the presence of an accelerated aging phenotype across different ...

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, including diabetes, neurodegeneration, and cancer. In recent years, new functions of sirtuins have
