The DNA damage response acts as a safeguardagainst harmful DNA–RNA hybrids ofdifferent origins
(EMBO Press, 2019-07-24)
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 ...

The chromatin network helps prevent cancer-associated mutagenesis at transcription-replication conflicts
(Nature Research, 2023)
Genome instability is a feature of cancer cells, transcription being an important source of DNA damage. This is in large part associated with R-loops, which hamper replication, especially at head-on transcription-replication ...

FANCD2 facilitates replication through common fragile sites
(Elsevier, 2016)
Common fragile sites (CFSs) are genomic regions that are unstable under conditions of replicative stress. Although the characteristics of CFSs that render them vulnerable to stress are mainly associated with replication, ...

Spontaneous DNA-RNA hybrids: differential impacts throughout the cell cycle
(Taylor & Francis, 2020)
A large body of research supports that transcription plays a major role among the many sources of replicative stress contributing to genome instability. It is therefore not surprising that the DNA damage response has a ...

The antitumor drugs trabectedin and lurbinectedin induce transcription-dependent replication stress and genome instability
(American Association for Cancer Research, 2019)
R-loops are a major source of replication stress, DNA damage, and genome instability, which are major hallmarks of cancer cells. Accordingly, growing evidence suggests that R-loops may also be related to cancer. Here we ...
