Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription [PDF]

open access: yes, 2014
Post-translational modifications of proteins have emerged as a major mechanism for regulating gene expression. However, our understanding of how histone modifications directly affect chromatin function remains limited.

Histone methylation by PRC2 is inhibited by active chromatin marks [PDF]

open access: yes, 2013
Chromatin modifiers serve as regulatory switches that control the cell cycle, maintain pluripotency and drive differentiation and development. Positive feedback mechanisms help to pass on transcriptional information from one generation of cells to the ...

Molecular Insights into Epigenetics and Cannabinoid Receptors

open access: yesBiomolecules, 2022
The actions of cannabis are mediated by G protein-coupled receptors that are part of an endogenous cannabinoid system (ECS). ECS consists of the naturally occurring ligands N-arachidonylethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG), their ...

Histone modifications influence the action of Snf2 family remodelling enzymes by different mechanisms [PDF]

open access: yes, 2007
Alteration of chromatin structure by chromatin modifying and remodelling activities is a key stage in the regulation of many nuclear processes. These activities are frequently interlinked, and many chromatin remodelling enzymes contain motifs that ...

MicroRNAs as new Characters in the Plot between Epigenetics and Prostate Cancer

open access: yesFrontiers in Genetics, 2011
Prostate cancer (PCA) still represents a leading cause of death. An increasing number of studies have documented that microRNAs (miRNAs), a subgroup of non-coding RNAs with gene regulatory functions, are differentially expressed in PCA respect to the ...

Complex exon-intron marking by histone modifications is not determined solely by nucleosome distribution [PDF]

open access: yes, 2010
It has recently been shown that nucleosome distribution, histone modifications and RNA polymerase II (Pol II) occupancy show preferential association with exons (“exon-intron marking”), linking chromatin structure and function to co-transcriptional ...

The reduced expression of trimethylation of histone H3 at lysine 27 in primary cutaneous mucinous carcinoma

open access: yesDermatologica Sinica, 2023
Primary cutaneous mucinous carcinoma (PCMC) is rare, and its carcinogenesis is unclear. Trimethylation of histone H3 at lysine 27 (H3K27me3) is a key regulator in chromatin remodeling-controlled transcription.

The Histone Database: an integrated resource for histones and histone fold-containing proteins [PDF]

open access: yesDatabase, 2011
Eukaryotic chromatin is composed of DNA and protein components-core histones-that act to compactly pack the DNA into nucleosomes, the fundamental building blocks of chromatin. These nucleosomes are connected to adjacent nucleosomes by linker histones. Nucleosomes are highly dynamic and, through various core histone post-translational modifications and ...
