Histone Modifications, Internucleosome Dynamics, and DNA Stresses: How They Cooperate to “Functionalize” Nucleosomes

open access: yesFrontiers in Genetics, 2022
Tight packaging of DNA in chromatin severely constrains DNA accessibility and dynamics. In contrast, nucleosomes in active chromatin state are highly flexible, can exchange their histones, and are virtually “transparent” to RNA polymerases, which ...

Diversity and Divergence of Dinoflagellate Histone Proteins

open access: yesG3: Genes, Genomes, Genetics, 2016
Histone proteins and the nucleosomal organization of chromatin are near-universal eukaroytic features, with the exception of dinoflagellates. Previous studies have suggested that histones do not play a major role in the packaging of dinoflagellate ...

Stability of histone post-translational modifications in samples derived from liver tissue and primary hepatic cells. [PDF]

open access: yesPLoS ONE, 2018
Chromatin structure, a key contributor to the regulation of gene expression, is modulated by a broad array of histone post-translational modifications (PTMs). Taken together, these "histone marks" comprise what is often referred to as the "histone code".

Post-Translational Modifications of Histones Are Versatile Regulators of Fungal Development and Secondary Metabolism

open access: yesToxins, 2022
Chromatin structure is a major regulator of DNA-associated processes, such as transcription, DNA repair, and replication. Histone post-translational modifications, or PTMs, play a key role on chromatin dynamics.

Epigenetic Regulation of S100A9 and S100A12 Expression in Monocyte-Macrophage System in Hyperglycemic Conditions

open access: yesFrontiers in Immunology, 2020
The number of diabetic patients in Europe and world-wide is growing. Diabetes confers a 2-fold higher risk for vascular disease. Lack of insulin production (Type 1 diabetes, T1D) or lack of insulin responsiveness (Type 2 diabetes, T2D) causes systemic ...

Strategies To Modulate Heritable Epigenetic Defects in Cellular Machinery: Lessons from Nature

open access: yesPharmaceuticals, 2012
Natural epigenetic processes precisely orchestrate the intricate gene network by expressing and suppressing genes at the right place and time, thereby playing an essential role in maintaining the cellular homeostasis.

Localization of Epigenetic Markers in Leishmania Chromatin

open access: yesPathogens, 2022
Eukaryotes use histone variants and post-translation modifications (PTMs), as well as DNA base modifications, to regulate DNA replication/repair, chromosome condensation, and gene expression. Despite the unusual organization of their protein-coding genes

The Histone Code of Toxoplasma gondii Comprises Conserved and Unique Posttranslational Modifications

open access: yesmBio, 2013
Epigenetic gene regulation has emerged as a major mechanism for gene regulation in all eukaryotes. Histones are small, basic proteins that constitute the major protein component of chromatin, and posttranslational modifications (PTM) of histones are ...
