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.

Emerging roles of telomeric chromatin alterations in cancer [PDF]
, 2019 Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...

Sirtuins and Disease: The Road Ahead [PDF]
Frontiers in Pharmacology, 2012 Sirtuins represent a promising new class of conserved histone deacetylases, originally identified in yeast. The activity of the sirtuin (SirT) family - made up of seven members (SirT1-7) - is NAD(+) dependent. Sirtuins target a wide range of cellular proteins in nucleus, cytoplasm, and mitochondria for post-translational modification by acetylation ...

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.

Sirtuins: New Roles for Sirtuins in Aging and Disease [PDF]
Innovation in Aging, 2020 Abstract Sirtuins are NAD+-dependent enzymes related to yeast silent information regulator-2, a histone deacetylase that prevents premature aging through chromatin silencing. Mammalian sirtuins, SIRT1-SIRT7, have key functions that protect against diverse aging-related pathologic states, from cancer to metabolic and neurodegenerative ...

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)

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.
