Transcription as a Threat to Genome Integrity
(Annual Reviews Inc., 2016)
Genomes undergo different types of sporadic alterations, including DNA damage, point mutations, and genome rearrangements, that constitute the basis for evolution. However, these changes may occur at high levels as a result ...

UAP56/DDX39B is a major cotranscriptional RNA–DNA helicase that unwinds harmful R loops genome-wide
(Cold Spring Harbor Laboratory Press, 2020)
Nonscheduled R loops represent a major source of DNA damage and replication stress. Cells have different ways to prevent R-loop accumulation. One mechanism relies on the conserved THO complex in association with cotranscriptional ...

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability
(2018)
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent ...

Histone Mutants Separate R Loop Formation from Genome Instability Induction
(Elsevier, 2017)
R loops have positive physiological roles, but they can also be deleterious by causing genome instability, and the mechanisms for this are unknown. Here we identified yeast histone H3 and H4 mutations that facilitate R ...
