Metabolic benefits from Sirt1 and Sirt1 activators
Current Opinion in Clinical Nutrition and Metabolic Care, 2009To evaluate the role of mammalian Sirt1 and Sirt1 activators in the protection from metabolic disorders such as diet-induced obesity, diabetes type 2, or nonalcoholic fatty liver disease.Sirtuins are highly conserved nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases that are activated by NAD+ and inhibited by NAD in its reduced form (NADH)

In the current study, bivalent compounds 1-17 constructed by covalently linking the ɛ-amino group of lysine in a tripeptidic scaffold to a functionality via a linker were prepared and examined for their inhibitory potencies against SIRT1, a prototypical member of the β-nicotinamide adenine dinucleotide (β-NAD+)-dependent sirtuin family of protein Nε ...

SIRT1 is the mammalian homologue of yeast silent information regulator (Sir)-2, a member of the sirtuin family of protein deacetylases which have gained much attention as mediators of lifespan extension in several model organisms. Induction of SIRT1 expression also attenuates neuronal degeneration and death in animal models of Alzheimer's disease and ...

Cardiovascular disease (CVD) is the leading cause of death worldwide, with aging as the key independent risk factor. Effective interventions are necessary to delay aging. Sirtuin1 (SIRT1), a NAD(+)-dependent histone deacetylase, is closely related to lifespan extension.

Sirtuin 1 (SIRT1) is a prototype mammalian NAD(+)-dependent protein deacetylase that has emerged as a key metabolic sensor in various metabolic tissues. Growing evidence suggests that SIRT1 regulates glucose and lipid metabolism through its deacetylase activity.

Sirtuin 1 (SIRT1), the mammalian homolog of SIR2, was originally identified as a NAD-dependent histone deacetylase, the activity of which is closely associated with lifespan under calorie restriction. Growing evidence suggests that SIRT1 regulates glucose or lipid metabolism through its deacetylase activity for over two dozen known substrates, and has ...

SIRT1 impacts upon diverse cellular processes via its roles in the determination of chromatin structure, chromatin remodelling and gene expression. This review covers the recent discoveries linking SIRT1 with the regulation of mammalian metabolism and considers ways in which abnormal metabolism in disease may, in turn, impact upon SIRT1 because of ...

DJ-1 activates SIRT1 through its direct binding to SIRT1
Biochemical and Biophysical Research Communications, 2016The DJ-1 gene is a ras-dependent oncogene and also a causative gene for a familial form of Parkinson's disease park7. DJ-1 is a multi-functional protein and plays roles in regulation of cell growth, cells death, metabolism and mitochondrial homeostasis against oxidative stress.

The intersection between regulatory pathways responsive to metabolic fluctuation on one hand, and to cellular stress on the other, is a fascinating area within which NAD/NADH responsive proteins play a major role [1, 2]. A key player amongst these is SIRT1, a member of the mammalian sirtuin family (SIRT1-7).
