R loops: new modulators of genome dynamics and function

JM Santos-Pereira, A Aguilera - Nature Reviews Genetics, 2015 - nature.com
R loops are nucleic acid structures composed of an RNA–DNA hybrid and a displaced
single-stranded DNA. Recently, evidence has emerged that R loops occur more often in the …

A double-edged sword: R loops as threats to genome integrity and powerful regulators of gene expression

K Skourti-Stathaki, NJ Proudfoot - Genes & development, 2014 - genesdev.cshlp.org
R loops are three-stranded nucleic acid structures that comprise nascent RNA hybridized
with the DNA template, leaving the nontemplate DNA single-stranded. R loops form naturally …

[HTML][HTML] Transcription-replication conflict orientation modulates R-loop levels and activates distinct DNA damage responses

S Hamperl, MJ Bocek, JC Saldivar, T Swigut… - Cell, 2017 - cell.com
Conflicts between transcription and replication are a potent source of DNA damage. Co-
transcriptional R-loops could aggravate such conflicts by creating an additional barrier to …

Causes of genome instability

A Aguilera, T García-Muse - Annual review of genetics, 2013 - annualreviews.org
Genomes are transmitted faithfully from dividing cells to their offspring. Changes that occur
during DNA repair, chromosome duplication, and transmission or via recombination provide …

R loops are linked to histone H3 S10 phosphorylation and chromatin condensation

M Castellano-Pozo, JM Santos-Pereira, AG Rondón… - Molecular cell, 2013 - cell.com
R loops are transcription byproducts that constitute a threat to genome integrity. Here we
show that R loops are tightly linked to histone H3 S10 phosphorylation (H3S10P), a mark of …

R loops and links to human disease

P Richard, JL Manley - Journal of molecular biology, 2017 - Elsevier
Aberrant R-loop structures are increasingly being realized as an important contributor to
human disease. R loops, which are mainly co-transcriptional, abundant RNA/DNA hybrids …

Genome-wide map of R-loop-induced damage reveals how a subset of R-loops contributes to genomic instability

L Costantino, D Koshland - Molecular cell, 2018 - cell.com
DNA-RNA hybrids associated with R-loops promote DNA damage and genomic instability.
The capacity of hybrids at different genomic sites to cause DNA damage was not known, and …
