ATM Breaks into Heterochromatin [PDF]

open access: yesMolecular Cell, 2008
Heterochromatin is refractory to DNA transactions, including repair. In a recent issue of Molecular Cell, Goodarzi et al. (2008) reveal how the central transducing kinase of the DNA damage response relieves this natural barrier by increasing heterochromatic DNA accessibility.

Assessing the Epigenetic Status of Human Telomeres [PDF]

open access: yes, 2019
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest.

DNA methylation dynamics in aging: How far are we from understanding the mechanisms? [PDF]

open access: yes, 2018
DNA methylation is currently the most promising molecular marker for monitoring aging and predicting life expectancy. However, the mechanisms underlying age-related DNA methylation changes remain mostly undiscovered.Here we discuss the current knowledge ...

High resolution physical mapping of single gene fragments on pachytene chromosome 4 and 7 of Rosa [PDF]

open access: yes, 2015
Background: Rosaceae is a family containing many economically important fruit and ornamental species. Although fluorescence in situ hybridization (FISH)-based physical mapping of plant genomes is a valuable tool for map-based cloning, comparative ...

Non-mammalian model organisms in epigenetic research : an overview [PDF]

open access: yes, 2020
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.

Heterochromatin protein 1α interacts with parallel RNA and DNA G-quadruplexes

open access: yesNucleic Acids Research, 2019
The eukaryotic genome is functionally organized into domains of transcriptionally active euchromatin and domains of highly compact transcriptionally silent heterochromatin.

SIRT7 antagonizes human stem cell aging as a heterochromatin stabilizer

open access: yesProtein & Cell, 2020
SIRT7, a sirtuin family member implicated in aging and disease, is a regulator of metabolism and stress responses. It remains elusive how human somatic stem cell populations might be impacted by SIRT7. Here, we found that SIRT7 expression declines during

The cAMP signaling pathway regulates Epe1 protein levels and heterochromatin assembly.

open access: yesPLoS Genetics, 2022
The epigenetic landscape of a cell frequently changes in response to fluctuations in nutrient levels, but the mechanistic link is not well understood.

Patterns of Heterochromatin Transitions Linked to Changes in the Expression of Plasmodium falciparum Clonally Variant Genes

open access: yesMicrobiology Spectrum, 2023
The survival of malaria parasites in the changing human blood environment largely depends on their ability to alter gene expression by epigenetic mechanisms.

Fission yeast Caprin protein is required for efficient heterochromatin establishment. [PDF]

open access: yesPLoS Genet
Heterochromatin is a key feature of eukaryotic genomes that serves important regulatory and structural roles in regions such as centromeres. In fission yeast, maintenance of existing heterochromatic domains relies on positive feedback loops involving ...
