Preconception resveratrol intake against infertility: Friend or foe?

open access: yesReproductive Medicine and Biology, 2020
Background Resveratrol is an antiaging, antioxidant, anti‐inflammatory, and insulin‐sensitizing natural polyphenolic compound. Growing evidence indicates that resveratrol has potential therapeutic effects in infertile women with diminished ovarian ...

Sirtuins, Aging, and Metabolism [PDF]

open access: yesCold 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

Sirtuins: New Roles for Sirtuins in Aging and Disease [PDF]

open access: yesInnovation 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 ...

Exploration of the Fluorescent Properties and the Modulated Activities against Sirtuin Fluorogenic Assays of Chromenone-Derived Natural Products

open access: yesMolecules, 2018
Chromenone-derived natural products include chromones (flavone, isoflavone) and coumarins. Chromenone compounds not only exhibit impressive biological activities, but also are an important resource of experimentally used fluorophores, such as, 7-amino-4 ...

A High-Fat and High-Fructose Diet Exacerbates Liver Dysfunction by Regulating Sirtuins in a Murine Model

open access: yesLife
Metabolic dysfunction-associated steatotic liver disease (MASLD) is rapidly emerging as the most prevalent chronic liver disease, closely linked to the escalating rates of diabesity.

Assaying Chromatin Sirtuins [PDF]

open access: yes, 2013
Most of the sirtuins' nuclear substrates identified so far are histones or other chromatin-associated proteins and, thus, it is of special relevance the development of good biochemical techniques to analyze the biology of these proteins in the context of chromatin.

Sirtuin chemical mechanisms [PDF]

open access: yesBiochimica 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.
