Sirtuin 1 and Sirtuin 3: Physiological Modulators of Metabolism [PDF]

Physiological Reviews, 2012
The sirtuins are a family of highly conserved NAD+-dependent deacetylases that act as cellular sensors to detect energy availability and modulate metabolic processes. Two sirtuins that are central to the control of metabolic processes are mammalian sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3), which are localized to the nucleus and mitochondria ...

Cardiomyocyte-Specific Deletion of Sirtuin 5 Accelerates the Development of Heart Failure Upon Dysregulating Purine Metabolism. [PDF]

Acta Physiol (Oxf)
ABSTRACT Aim Sirtuin 5 (SIRT5), a mitochondrial NAD+‐dependent deacylase, regulates fundamental cellular pathways, including energy substrate metabolism. The current study is designed to better elucidate the role of SIRT5 in the development of heart failure (HF). Methods Mice with cardiomyocyte‐specific deletion (cSirt5−/−) or overexpression (cSirt5‐Tg)

Modulation of PGC-1α activity as a treatment for metabolic and muscle-related diseases [PDF]

, 2014
Physical inactivity is a predisposing factor for various disease states including obesity, cardiovascular disease, as well as for certain types of cancer. Regular endurance exercise mediates several beneficial effects such as increased energy expenditure

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Sirtuin 2 Deficiency Increases Bacterial Phagocytosis by Macrophages and Protects from Chronic Staphylococcal Infection

Frontiers in Immunology, 2017
Sirtuin 2 (SIRT2) is one of the seven members of the family of NAD+-dependent histone deacetylases. Sirtuins target histones and non-histone proteins according to their subcellular localization, influencing various biological processes.

Identification of a novel polyprenylated acylphloroglucinol‑derived SIRT1 inhibitor with cancer‑specific anti-proliferative and invasion-suppressing activities [PDF]

, 2014
SIRT1, a class III histone deacetylase, plays a critical role in regulating cancer cell growth, migration and invasion, which makes it a potential target for cancer therapeutics.

The sirtuins in the pathogenesis of cancer

Clinical Epigenetics, 2010
Abstract Aging is the natural trace that time leaves behind on life during blossom and maturation, culminating in senescence and death. This process is accompanied by a decline in the healthy function of multiple organ systems, leading to increased incidence and mortality from diseases such as diabetes, cancer, cardiovascular disease, and ...

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Regulation of histone H2A.Z expression is mediated by sirtuin 1 in prostate cancer [PDF]

, 2013
Histone variants seem to play a major role in gene expression regulation. In prostate cancer, H2A.Z and its acetylated form are implicated in oncogenes’ upregulation.
