Poly(ADP-Ribosyl)ation affects stabilization of CHE-1 protein in response to DNA damage [PDF]

, 2011
Post-translation modifications play a crucial role in coordinating the cellular response to DNA damage. Double strand DNA breaks (DSBs) trigger the activation of ATM and Chk2 kinases, which represent the primary transducers in the signalling cascade ...

The Adaptive Significance of Natural Genetic Variation in the DNA Damage Response of Drosophila melanogaster. [PDF]

, 2016
Despite decades of work, our understanding of the distribution of fitness effects of segregating genetic variants in natural populations remains largely incomplete. One form of selection that can maintain genetic variation is spatially varying selection,

Moving From Poly (ADP-Ribose) Polymerase Inhibition to Targeting DNA Repair and DNA Damage Response in Cancer Therapy.

Journal of Clinical Oncology, 2019
The DNA damage response (DDR) pathway coordinates the identification, signaling, and repair of DNA damage caused by endogenous or exogenous factors and regulates cell-cycle progression with DNA repair to minimize DNA damage being permanently passed ...

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

DNA damage-induced YTHDC1 O-GlcNAcylation promotes homologous recombination by enhancing m6A binding

Fundamental Research
N6-methyladenosine (m6A) is the most prevalent internal RNA modification, and its regulators include writers, readers and erasers. m6A is under stringent control and takes part in many biological events, but it is not known whether there is an interplay ...

A Genetic Map of the Response to DNA Damage in Human Cells

Cell, 2019
The response to DNA damage is critical for cellular homeostasis, tumor suppression, immunity and gametogenesis. In order to provide an unbiased and global view of the DNA damage response in human cells, we undertook 28 CRISPR/Cas9 screens against 25 ...

DNA damage response and hematological malignancy [PDF]

International Journal of Hematology, 2017
DNA damage is a serious threat to cellular homeostasis. Damaged DNA leads to genomic instability, mutation, senescence, and/or cell death. DNA damage triggers a cellular response called the DNA damage response (DDR), followed by activation of the DNA repair machinery. DDR both maintains cellular homeostasis and prevents cancer development.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

The DNA damage checkpoint pathway promotes extensive resection and nucleotide synthesis to facilitate homologous recombination repair and genome stability in fission yeast. [PDF]

, 2014
DNA double-strand breaks (DSBs) can cause chromosomal rearrangements and extensive loss of heterozygosity (LOH), hallmarks of cancer cells. Yet, how such events are normally suppressed is unclear.

Functional transcription promoters at DNA double-strand breaks mediate RNA-driven phase separation of damage response factors

Nature Cell Biology, 2019
Damage-induced long non-coding RNAs (dilncRNA) synthesized at DNA double-strand breaks (DSBs) by RNA polymerase II are necessary for DNA-damage-response (DDR) focus formation.
