It takes two to tango: NAD+ and sirtuins in aging/longevity control [PDF]

open access: yes, 2016
The coupling of nicotinamide adenine dinucleotide (NAD+) breakdown and protein deacylation is a unique feature of the family of proteins called ‘sirtuins.’ This intimate connection between NAD+ and sirtuins has an ancient origin and provides a ...

MicroRNA Regulation of SIRT1 [PDF]

open access: yesFrontiers in Physiology, 2012
SIRT1 is an NAD-dependent deacetylase that regulates stress response pathways. By deacetylating transcription factors and co-factors, SIRT1 modulates metabolism, inflammation, hypoxic responses, circadian rhythms, cell survival, and longevity. Since SIRT1 plays a key role in regulating pathways involved in cardiovascular diseases and metabolic diseases

Hypothalamic Sirt1 in aging

open access: yesAging, 2014
There is an old Japanese proverb saying, “After rain falls, the ground hardens.” This proverb illustrates what has happened to the research field on the importance of sirtuins in the regulation of aging and longevity. The Sir2 (silent information regulator 2) family of protein deacylases, now called sirtuins, have been shown to regulate aging and ...
