Sirtuins, Aging, and Metabolism [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2011
Sirtuins are nicotinamide adenine dinucleotide (NAD)-dependent protein deacetylases that link protein acetylation, metabolism, aging, and diseases of aging. Sirtuins were initially found to slow aging in lower organisms and more recently shown to mediate many effects of calorie restriction on metabolism and longevity in mammals. This chapter focuses on

Spermidine Reproduces the Anti‐Inflammatory Effects of Intermittent Fasting and Prevents Urate and Calcium Pyrophosphate Crystal‐Induced Inflammation

Arthritis &Rheumatology, EarlyView.
Objective Gout caused by the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL) 1β via activation of the NLRP3 inflammasome.

The Longevity of Sirtuins

Cell Reports, 2012
Controversy has recently arisen over the role of sirtuins in metazoan aging. In this issue of Cell Reports, Banerjee et al. demonstrate that Drosophila Sir2 is necessary for life span extension in response to dietary restriction and that its overexpression in the fat body increases the life span.

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Sirtuins and Pyridine Nucleotides [PDF]

Circulation Research, 2012
The silencer information regulator (Sir) family of proteins has attracted much attention during the past decade due to its prominent role in metabolic homeostasis in mammals. The Sir1–4 proteins were first discovered in yeast as nicotinamide adenine dinucleotide (NAD + )-dependent deacetylases, which through a gene ...

Sirtuin E is a fungal global transcriptional regulator that determines the transition from the primary growth to the stationary phase [PDF]

, 2017
In response to limited nutrients, fungal cells exit the primary growth phase, enter the stationary phase, and cease proliferation. Although fundamental to microbial physiology in many environments, the regulation of this transition is poorly understood ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Selective Sirt2 inhibition by ligand-induced rearrangement of the active site. [PDF]

, 2015
Sirtuins are a highly conserved class of NAD(+)-dependent lysine deacylases. The human isotype Sirt2 has been implicated in the pathogenesis of cancer, inflammation and neurodegeneration, which makes the modulation of Sirt2 activity a promising ...

Chemically Induced Degradation of Sirtuin 2 (Sirt2) by a Proteolysis Targeting Chimera (PROTAC) Based on Sirtuin Rearranging Ligands (SirReals).

Journal of Medicinal Chemistry, 2017
Here we report the development of a proteolysis targeting chimera (PROTAC) based on the combination of the unique features of the sirtuin rearranging ligands (SirReals) as highly potent and isotype-selective Sirt2 inhibitors with thalidomide, a bona fide

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).
