Human neuronal cells: epigenetic aspects

Biomolecular Concepts, 2013
Histone acetyltransferases (HATs) and histone deacetylases (HDACs) promote histone posttranslational modifications, which lead to an epigenetic alteration in gene expression. Aberrant regulation of HATs and HDACs in neuronal cells results in pathological

The histone octamer influences the wrapping direction of DNA on it: Brownian dynamics simulation of the nucleosome chirality [PDF]

Journal of Theoretical Biology 235 (2005) 365-372, 2005
In eukaryote nucleosome, DNA wraps around a histone octamer in a left-handed way. We study the process of chirality formation of nucleosome with Brownian dynamics simulation. We model the histone octamer with a quantitatively adjustable chirality: left-handed, right-handed or non-chiral, and simulate the dynamical wrapping process of a DNA molecule on ...

On the ubiquitous presence of histone acetyltransferase B in eukaryotes [PDF]

, 1985
Histone acetyltransferase B activity has been found in pea (Pisun sativum) seedlings. The enzyme has been partially purified and it has been found that it is highly specific for H4.

Combined Immediate‐Release and Extended‐Release Formulation of Sodium Valproate Provides Stable Plasma Levels for Inhibition of Histone Deacetylation

Clinical Pharmacology in Drug Development, EarlyView.
Abstract A modified controlled‐release sodium valproate formulation (VAL001, test) was compared with an approved enteric‐coated tablet formulation (Absenor, reference). Pharmacokinetics and safety/tolerability were evaluated in healthy subjects to bridge with positive efficacy results from an early‐phase patient trial of valproate in combination with ...

Histone malonylation is regulated by SIRT5 and KAT2A

iScience, 2023
Summary: The posttranslational modification lysine malonylation is found in many proteins, including histones. However, it remains unclear whether histone malonylation is regulated or functionally relevant. Here, we report that availability of malonyl-co-

Targeted Derepression of the Human Immunodeficiency Virus Type 1 Long Terminal Repeat by Pyrrole-Imidazole Polyamides [PDF]

, 2002
The host factor LSF represses the human immunodeficiency virus type 1 long terminal repeat (LTR) by mediating recruitment of histone deacetylase. We show that pyrrole-imidazole polyamides targeted to the LTR can specifically block LSF binding both in ...

Heart failure and obesity: Translational approaches and therapeutic perspectives. A scientific statement of the Heart Failure Association of the ESC

European Journal of Heart Failure, EarlyView.
Abstract Obesity and heart failure (HF) represent two growing pandemics. In the general population, obesity affects one in eight adults and is linked with an increased risk for HF. Obesity is even more common in patients with HF, where it complicates the diagnosis of HF and is linked with worse symptoms and impaired exercise capacity. Over the past few

Pyrido- and benzisothiazolones as inhibitors of histone acetyltransferases (HATs) [PDF]

, 2014
Histone acetyltransferases (HATs) are interesting targets for the treatment of cancer and HIV infections but reports on selective inhibitors are very limited.

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.

DeepChrome: Deep-learning for predicting gene expression from histone modifications [PDF]

arXiv, 2016
Motivation: Histone modifications are among the most important factors that control gene regulation. Computational methods that predict gene expression from histone modification signals are highly desirable for understanding their combinatorial effects in gene regulation. This knowledge can help in developing 'epigenetic drugs' for diseases like cancer.
