Histone Modifications in Senescence-Associated Resistance to Apoptosis by Oxidative Stress

Redox Biology, 2013
Aging and age-related diseases are associated with cellular senescence that results in variable apoptosis susceptibility to oxidative stress. Although fibroblast senescence has been associated with apoptosis resistance, mechanisms for this have not been ...

Histone acetyltransferase p300 mediates histone acetylation of PS1 and BACE1 in a cellular model of Alzheimer's disease. [PDF]

PLoS ONE, 2014
Epigenetic modifications, particularly histone acetylation, have been implicated in Alzheimer's disease (AD). While previous studies have suggested that histone hypoacetylation may regulate the expression of genes associated with memory and learning in ...

Histone Lysine and Genomic Targets of Histone Acetyltransferases in Mammals [PDF]

BioEssays, 2018
Histone acetylation has been recognized as an important post‐translational modification of core nucleosomal histones that changes access to the chromatin to allow gene transcription, DNA replication, and repair. Histone acetyltransferases were initially identified as co‐activators that link DNA‐binding transcription factors to the general ...

Compensation Response to Hepatic Gluconeogenesis via β‐Hydroxybutyrylation of FBP1 and PCK1 in Dairy Cows

Animal Research and One Health, EarlyView.
(1) Kbhb modification of FBP1 and PCK1 is involved in regulation of the gluconeogenesis pathway. (2) Kbhb of FBP1 and PCK1 is catalyzed by p300 and removed by HDACs. (3) BHB induced an increase in the enzymatic activity of FBP1 and PCK1 through Kbhb modification at the K43 site of FBP1 and the K191 site of PCK1.

Spermidine Reproduces the Anti‐Inflammatory Effects of Intermittent Fasting and Prevents Urate and Calcium Pyrophosphate Crystal‐Induced Inflammation

Arthritis &Rheumatology, EarlyView.
Objective Gout caused by the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL) 1β via activation of the NLRP3 inflammasome.

CREB-Binding Protein Is a Mediator of Neuroblastoma Cell Death Induced By the Histone Deacetylase Inhibitor Trichostatin A

Neoplasia: An International Journal for Oncology Research, 2007
The cytotoxic mechanism of the histone deacetylase inhibitor (HDACI) Trichostatin A (TSA) was explored in a neuroblastoma (NB) model. TSA induces cell death in neuroblastic-type NB cells by increasing the acetylation of Ku70, a Bax-binding protein.

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

The histone chaperones Vps75 and Nap1 form ring-like, tetrameric structures in solution [PDF]

, 2013
NAP-1 fold histone chaperones play an important role in escorting histones to and from sites of nucleosome assembly and disassembly. The two NAP-1 fold histone chaperones in budding yeast, Vps75 and Nap1, have previously been crystalized in a ...

Clock gene dysregulation in epilepsy: A systematic review

Epilepsia Open, EarlyView.
Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.
