Extracellular Histones as Exosome Membrane Proteins Regulated by Cell Stress
Histones are conserved nuclear proteins that function as part of the nucleosome in the regulation of chromatin structure and gene expression. Interestingly, extracellular histones populate biofluids from healthy individuals, and when elevated, may ...

Ageing-Related Changes to H3K4me3, H3K27ac, and H3K27me3 in Purified Mouse Neurons
Neurons are central to lifelong learning and memory, but ageing disrupts their morphology and function, leading to cognitive decline. Although epigenetic mechanisms are known to play crucial roles in learning and memory, neuron-specific genome-wide ...

Structure and function of archaeal histones. [PDF]
The genomes of all organisms throughout the tree of life are compacted and organized in chromatin by association of chromatin proteins. Eukaryotic genomes encode histones, which are assembled on the genome into octamers, yielding nucleosomes.

Non-mammalian model organisms in epigenetic research : an overview [PDF]
Recent advances in sequencing technology and genome editing tools had an indisputably enormous impact on our understanding of complex biological pathways and their genetic and epigenetic regulation.

Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Hansemann’s anaplastic theory of cancer after 135 years
Summary: The term “anaplasia” was coined in 1890 to describe chromosomal changes common to primordial cancer cells, but ever since the mechanisms whereby a cell becomes anaplastic has been the subject of much speculation.

Diversity and Divergence of Dinoflagellate Histone Proteins
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 ...

The Snf2 Homolog Fun30 acts as a homodimeric ATP-dependent chromatin-remodeling enzyme [PDF]
The Saccharomyces cerevisiae Fun30 (Function unknown now 30) protein shares homology with an extended family of Snf2-related ATPases. Here we report the purification of Fun30 principally as a homodimer with a molecular mass of about 250 kDa.

Comprehensive analysis of genomic mutations, gene expression, DNA methylation, and pathway analysis of TCGA data was carried out to define cancer types in which proteasome subunits expression is associated with worse survival. Albeit the effect of specific proteasome subunits on cellular function, the main role of the proteasome is better evaluated ...
