compactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولSirtuins in mammals: insights into their biological function.
Sirtuins are a conserved family of proteins found in all domains of life. The first known sirtuin, Sir2 (silent information regulator 2) of Saccharomyces cerevisiae, from which the family derives its name, regulates ribosomal DNA recombination, gene silencing, DNA repair, chromosomal stability and longevity. Sir2 homologues also modulate lifespan in worms and flies, and may underlie the benefic...
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...
متن کاملSirtuins, aging and diseases
SIR2 and related genes (sirtuins) are NAD-dependent deacetylases that link metabolism, protein acetylation and aging in a variety of species. Sirtuins are also involved in the longevity conferred by dietary or calorie restriction (CR). The mammalian sirtuins SIRT1-7 are involved in changes in stress resistance and metabolism that are triggered by CR, which not only extends life span, but also p...
