Effects of an Unusual Poison Identify a Lifespan Role for Topoisomerase 2 in Saccharomyces Cerevisiae [PDF]
, 2017 A progressive loss of genome maintenance has been implicated as both a cause and consequence of aging. Here we present evidence supporting the hypothesis that an age-associated decay in genome maintenance promotes aging in Saccharomyces cerevisiae (yeast)

Cell, 2014 The mammalian sirtuins have emerged as critical regulators of cellular stress resistance, energy metabolism, and tumorigenesis. In some contexts, they delay the onset of age-related diseases and promote a healthy lifespan. The seven mammalian sirtuins, SIRT1-7, share a highly conserved NAD+-binding catalytic core domain although they exhibit distinct ...

Hepatology, EarlyView., 2022 NRPT 1X reduces ALT and ceramide 14:0 in 65% of subjects as compared to only 28% in the placebo group. Abstract Background and Aims The prevalence of NAFLD is increasing globally and on a path to becoming the most frequent cause of chronic liver disease. Strategies for the prevention and treatment of NAFLD are urgently needed.

Inverse association of circulating SIRT1 and adiposity. A study on underweight, normal weight, and obese patients [PDF]
, 2018 Context: Sirtuins (SIRTs) are NAD+-dependent deacetylases, cellular sensors to detect energy availability, and modulate metabolic processes. SIRT1, the most studied family member, influences a number of tissues including adipose tissue.

Retinal Aging and Sirtuins [PDF]
Ophthalmic Research, 2010 The process of aging involves the accumulating changes in the microenvironment that lead to cell senescence or apoptosis, and subsequent tissue or organ dysfunction. Multiple extrinsic and intrinsic events that cause DNA instability are associated with aging.

Microbial Cell, 2016 Increasing the stability or dynamics of the actin cytoskeleton can extend lifespan in C. elegans and S. cerevisiae. Actin cables of budding yeast, bundles of actin filaments that mediate cargo transport, affect lifespan control through effects on ...

Vascular smooth muscle Sirtuin-1 protects against aortic dissection during Angiotensin II-induced hypertension [PDF]
, 2015 BACKGROUND: Sirtuin-1 (SirT1), a nicotinamide adenine dinucleotide(+)-dependent deacetylase, is a key enzyme in the cellular response to metabolic, inflammatory, and oxidative stresses; however, the role of endogenous SirT1 in the vasculature has not ...

Sirt1 expression is associated with CD31 expression in blood cells from patients with chronic obstructive pulmonary disease [PDF]
, 2016 Background: Cigarette smoke induced oxidative stress has been shown to reduce silent information regulator 1 (Sirt1) levels in lung tissue from smokers and patients with COPD patients.

Sirtuin chemical mechanisms [PDF]
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2010 Sirtuins are ancient proteins widely distributed in all lifeforms of earth. These proteins are universally able to bind NAD(+), and activate it to effect ADP-ribosylation of cellular nucleophiles. The most commonly observed sirtuin reaction is the ADP-ribosylation of acetyllysine, which leads to NAD(+)-dependent deacetylation.
