Sirtuin-activating compound. Sirtuin-activating compounds ( STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases. [ 1]
That same year, David Sinclair joined the Guarente lab, and they developed the hypothesis that caloric restriction slows aging by activation of sirtuins. [8] The Kenyon and Guarente labs came to lead the field studying the genetics of aging. [9] In 1995 the Guarente lab identified the gene SIR4 (Silent information regulator 4) as a longevity ...
Sirtuin. Sirtuins are a family of signaling proteins involved in metabolic regulation. [ 2][ 3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [ 2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity ...
Sirtuin 6 (SIRT6 or Sirt6) is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. [ 5 ] [ 6 ] [ 7 ] In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation . [ 5 ]
This is a list, in year order, of the most notable films produced in the Soviet Occupation Zone of Germany and the socialist German Democratic Republic (GDR, East Germany) from 1945 until German Reunification in October 1990. The state owned East German film company DEFA produced about 800 feature films between 1946 and 1992.
Sirtuin 2. NAD-dependent deacetylase sirtuin 2 is an enzyme that in humans is encoded by the SIRT2 gene. [5] [6] [7] SIRT2 is an NAD+ (nicotinamide adenine dinucleotide)-dependent deacetylase. Studies of this protein have often been divergent, highlighting the dependence of pleiotropic effects of SIRT2 on cellular context.
