Heterochromatin: an epigenetic point of view in aging [PDF]
Experimental and Molecular Medicine, 2020 Aging is an inevitable process of life. Defined by progressive physiological and functional loss of tissues and organs, aging increases the risk of mortality for the organism.

Nature Communications, 2021 The heterochromatin compartment is key for genome stability and cell fate transitions. Here, by tracking the heterochromatin response to UV damage in real time, the authors reveal how heterochromatin features are preserved following a genotoxic stress ...

Heterochromatin as an Important Driver of Genome Organization
Frontiers in Cell and Developmental Biology, 2020 Heterochromatin is a constituent of eukaryotic genomes with functions spanning from gene expression silencing to constraining DNA replication and repair.

Nature reviews. Molecular cell biology, 2022 Heterochromatin is characterized by dimethylated or trimethylated histone H3 Lys9 (H3K9me2 or H3K9me3, respectively) and is found at transposable elements, satellite repeats and genes, where it ensures their transcriptional silencing.

Epigenetics & Chromatin, 2022 Budding yeast Saccharomyces cerevisiae and fission yeast Schizosaccharomyces pombe are good models for heterochromatin study. In S. pombe, H3K9 methylation and Swi6, an ortholog of mammalian HP1, lead to heterochromatin formation. However, S.

Heterochromatin organization and phase separation
The Nucleus, 2023 The eukaryotic nucleus displays a variety of membraneless compartments with distinct biomolecular composition and specific cellular activities. Emerging evidence indicates that protein-based liquid–liquid phase separation (LLPS) plays an essential role ...

Global regulation of heterochromatin spreading by Leo1 [PDF]
Open Biology, 2015 Heterochromatin plays important roles in eukaryotic genome regulation. However, the repressive nature of heterochromatin combined with its propensity to self-propagate necessitates robust mechanisms to contain heterochromatin within defined boundaries ...

Constitutive Heterochromatin in Eukaryotic Genomes: A Mine of Transposable Elements
Cells, 2022 Transposable elements (TEs) are abundant components of constitutive heterochromatin of the most diverse evolutionarily distant organisms. TEs enrichment in constitutive heterochromatin was originally described in the model organism Drosophila ...

The proper splicing of RNAi factors is critical for pericentric heterochromatin assembly in fission yeast. [PDF]
PLoS Genetics, 2014 Heterochromatin preferentially assembles at repetitive DNA elements, playing roles in transcriptional silencing, recombination suppression, and chromosome segregation.

DNA Double-Strand Break Repair: All Roads Lead to HeterochROMAtin Marks
Frontiers in Genetics, 2021 In response to DNA double-strand breaks (DSBs), chromatin modifications orchestrate DNA repair pathways thus safeguarding genome integrity. Recent studies have uncovered a key role for heterochromatin marks and associated factors in shaping DSB repair ...
