Sirtuins: the future insight.
Sirtuins are evolutionary conserved NAD+ dependent acetyl-lysine deacetylases and ADP ribosyltransferases dual-function enzymes involved in the regulation of metabolism and lifespan. Sirtuins represent a promising new class of III NAD dependent histone deacetylases that regulate a number of physiological processes, originally identified in yeast. Sirtuins regulate various normal and abnormal ce...
متن کاملInsight on future quantum networks.
I n the past few years, significant improvements have been achieved in quantum communication. To extend the communication range, however, a new technology based on quantum memories needs to be developed. In PNAS, Bao et al. (1) give an example of the building blocks of the quantum communication networks we may expect to see in the future. These complex systems will be built on the basic ingredi...
متن کاملSirtuins at a glance.
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; Kaeberlein et al., 1999). Since then, sirtuins have been shown to also regulate longevity in other lower organisms, such as flies and worms (Tissenbaum and Guarente, 2001; Rogina and Helfand, 2004). In mammals, there are s...
متن کاملSirtuins, aging, and metabolism.
Sirtuins are nicotinamide adenine dinucleotide (NAD)-dependent protein deacetylases that link protein acetylation, metabolism, aging, and diseases of aging. Sirtuins were initially found to slow aging in lower organisms and more recently shown to mediate many effects of calorie restriction on metabolism and longevity in mammals. This chapter focuses on two key mammalian sirtuins, SIRT1 (which r...
متن کاملSirtuins, Bioageing, and Cancer
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, which places the various family members at crit...
