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

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 ...

Cell Reports, 2012 Controversy has recently arisen over the role of sirtuins in metazoan aging. In this issue of Cell Reports, Banerjee et al. demonstrate that Drosophila Sir2 is necessary for life span extension in response to dietary restriction and that its overexpression in the fat body increases the life span.

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, metabolism and genome stability.

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 ...

Pyrroloquinoline quinone increases the expression and activity of Sirt1 and -3 genes in HepG2 cells. [PDF]
, 2015 Sirtuin (Sirt) 1 and Sirt 3 are nicotinamide adenine dinucleotide ((+))-dependent protein deacetylases that are important to a number of mitochondrial-related functions; thus, identification of sirtuin activators is important. Herein, we hypothesize that

SIRT6 regulates Ras-related protein R-Ras2 by lysine defatty-acylation
eLife, 2017 The Ras family of GTPases are important in cell signaling and frequently mutated in human tumors. Understanding their regulation is thus important for studying biology and human diseases.
