Progress of deacetylase SIRTs in pathogenesis of Parkinson's disease [PDF]

open access: yesJichu yixue yu linchuang
Sirtuins(SIRTs), a group of NAD+ dependent deacetylases, have attracted considerable attention in the field of neuro-degenerative diseases, especially Parkinson's disease (PD).

Active regulator of SIRT1 is required for cancer cell survival but not for SIRT1 activity [PDF]

open access: yes, 2013
The NAD+-dependent deacetylase SIRT1 is involved in diverse cellular processes, and has also been linked with multiple disease states. Among these, SIRT1 expression negatively correlates with cancer survival in both laboratory and clinical studies ...

Sirtuins in Epigenetic Regulation [PDF]

open access: yesChemical Reviews, 2015
1.1. Discovery of Sirtuins The founding member of sirtuin is the yeast-silencing information regulator 2 (SIR2) protein, one of four proteins (SIR1–4) required for silencing the mating-type information loci in yeast.1 SIR2–4, but not SIR1, are also required for gene silencing at telomeres.2 SIR2 also mediates gene silencing at the rDNA (rDNA) loci ...

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

open access: yesAnimal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Autophagy in DNA Damage Response [PDF]

open access: yes, 2015
DNA damage response (DDR) involves DNA repair, cell cycle regulation and apoptosis, but autophagy is also suggested to play a role in DDR. Autophagy can be activated in response to DNA-damaging agents, but the exact mechanism underlying this activation ...

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

open access: yesAnimal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

SIRT6 Knockout Cells Resist Apoptosis Initiation but Not Progression: A Computational Method to Evaluate the Progression of Apoptosis

open access: yes, 2017
Apoptosis is essential for numerous processes, such as development, resistance to infections, and suppression of tumorigenesis. Here, we investigate the influence of the nutrient sensing and longevity-assuring enzyme SIRT6 on the dynamics of apoptosis ...

Nicotinamide Reverses the Warburg Effect in CHO Cell Culture

open access: yesBiotechnology and Bioengineering, EarlyView.
Abstract The Warburg effect, the preferential conversion of glucose‐derived pyruvat to lactate despite available oxygen, is a key feature of Chinese hamster ovary (CHO) cell culture. Lactate accumulation in recombinant protein‐producing cell culture is an inefficient usage of glucose, as well as being deleterious to cells.

Differential expression of sirtuins in the aging rat brain [PDF]

open access: yes, 2015
Although there are seven mammalian sirtuins (SIRT1-7), little is known about their expression in the aging brain. To characterize the change(s) in mRNA and protein expression of SIRT1-7 and their associated proteins in the brain of "physiologically" aged
