Sirtuin Catalysis and Regulation [PDF]

Journal of Biological Chemistry, 2012
Sirtuins are a family of NAD(+)-dependent protein deacetylases/deacylases that dynamically regulate transcription, metabolism, and cellular stress response. Their general positive link with improved health span in mammals, potential regulation of pathways mediated by caloric restriction, and growing links to human disease have spurred interest in ...

Animal models of idiopathic membranous nephropathy: Recent advances and future perspectives

Animal Models and Experimental Medicine, EarlyView.
This review focuses on the evolution of idiopathic membranous nephropathy (IMN) animal models from traditional approaches (Heymann nephritis, C‐BSA, APA) to antigen‐specific models (PLA2R, THSD7A), critically evaluating their advances and limitations in replicating human IMN pathology.

A pilot study of the modulation of sirtuins on arylamine N-acetyltransferase 1 and 2 enzymatic activity

Acta Pharmaceutica Sinica B, 2018
Arylamine N-acetyltransferase (NAT; E.C. 2.3.1.5) enzymes are responsible for the biotransformation of several arylamine and hydrazine drugs by acetylation.

Sirtuins in Epigenetic Regulation [PDF]

Chemical 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 ...

ApoE‐ and Cfh‐deficient mice exhibit structural and molecular features of human early–intermediate retinal degeneration

Animal Models and Experimental Medicine, EarlyView.
Age‐related macular degeneration (AMD) involves lipid dysregulation and complement overactivation. Here, we characterize a double‐knockout ApoE−/−/Cfh−/− mouse as a model of early–intermediate retinal degeneration. These mice exhibit retinal pigment epithelium thinning, Bruch's membrane thickening, lipid accumulation, enhanced C5b‐9 deposition ...

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

Animal 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.

Indole‐3‐Acetic Acid Protects Bovine Hepatocytes Against Palmitic Acid‐Induced Lipid Accumulation and ER Stress Through SIRT3

Animal Research and One Health, EarlyView.
Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.

Substrate‐Selective Inhibition of the SARS‐CoV‐2 Papain‐Like Protease: Inhibition of Hydrolysis of Human Over Viral Substrates

Chemistry – A European Journal, EarlyView.
The SARS‐CoV‐2 papain‐like protease (PLpro) is a medicinal chemistry target. Here we report mass spectrometry assays employing oligopeptide substrates based on the sequences of the viral polyproteins 1a/1ab and on an ISG15‐modified human protein, which enabled the identification of substrate‐selective PLpro inhibitors.
