Sirtuins are a family of enzymes, which govern genome regulation, stress response, metabolic homeostasis and lifespan. Among all the discovered human isoforms (SIRT1-7), SIRT1 emerged as a promising molecular target for the treatment of several diseases. The SIRT1 activators have shown beneficial effects in diabetes, obesity, disorders related to aging, cardiovascular and neurodegenerative dise...

Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...

BACKGROUND Mammalian sirtuins are homologs to the yeast silent information regulator 2 (Sir2), which is an NAD-dependent deacetylase. Sirtuins are comprised of 7 proteins, and each has different target proteins. Sirtuin 1 (SIRT1) plays important roles in maintaining metabolic functions and immune responses, and SIRT3 protects cells from oxidative stress-induced cell death. Both SIRT1 and SIRT3 ...
