The DNA damage response acts as a safeguardagainst harmful DNA–RNA hybrids ofdifferent origins [PDF]
, 2019 Despite playing physiological roles in specific situations, DNA–RNA hybrids threat genome integrity. To investigate how cells do counteract spontaneous DNA–RNA hybrids, here we screen an siRNA library covering 240 human DNA damage response (DDR) genes ...

Co-transcriptional R-loops are the main cause of estrogen-induced DNA damage. [PDF]
, 2016 The hormone estrogen (E2) binds the estrogen receptor to promote transcription of E2-responsive genes in the breast and other tissues. E2 also has links to genomic instability, and elevated E2 levels are tied to breast cancer.

Bacterial Genotoxin-Induced DNA Damage and Modulation of the Host Immune Microenvironment
Toxins, 2020 Bacterial genotoxins (BTGX) induce DNA damage, which results in senescence or apoptosis of the target cells if not properly repaired. Three BTGXs have been identified: the cytolethal distending toxin (CDT) family produced by several Gram-negative ...

DNA damage and repair proteins in cellular response to sulfur mustard in Iranian veterans more than two decades after exposure [PDF]
, 2018 Delayed effects of sulfur mustard (SM) exposure on the levels of five important damage/repair proteins were investigated in 40 SM-exposed veterans of Iran-Iraq war and 35 unexposed controls.

The concerted roles of FANCM and Rad52 in the protection of common fragile sites
Nature Communications, 2018 Fanconi anemia core proteins have been linked to common fragile site stability. Here the authors shed light into the role of FANCM in common fragile site protection by suppressing double-strand break formation and mitotic recombination.

Tyrosine dephosphorylation of H2AX modulates apoptosis and survival decisions. [PDF]
, 2009 Life and death fate decisions allow cells to avoid massive apoptotic death in response to genotoxic stress. Although the regulatory mechanisms and signalling pathways controlling DNA repair and apoptosis are well characterized, the precise molecular ...

MicroRNAs, damage levels, and DNA damage response control
Trends in Genetics, 2021 DNA damage-inducible miRNAs are likely to be functional in the DNA damage response. This response can elicit damage resolution and cell survival or apoptosis. The current, albeit incomplete, picture suggests that miRNAs can affect cell fate via modulation of key response proteins, but the question is, who's in charge?

Quantitative mechanisms of DNA damage sensing and signaling
, 2020 DNA damage occurs abundantly during normal cellular proliferation. This necessitates that cellular DNA damage response and checkpoint pathways monitor the cellular DNA damage load and that DNA damage signaling is quantitative.

Arabidopsis RecQl4A suppresses homologous recombination and modulates DNA damage responses [PDF]
, 2005 The DNA damage response and DNA recombination are two interrelated mechanisms involved in maintaining the integrity of the genome, but in plants they are poorly understood.
