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 ...

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 ...

Human THO–Sin3A interaction reveals new mechanisms to prevent R-loops that cause genome instability
(Wiley-Blackwell, 2017)
R-loops, formed by co-transcriptional DNA–RNA hybrids and a displaced DNA single strand (ssDNA), fulfill certain positive regulatory roles but are also a source of genomic instability. One key cellular mechanism to prevent ...

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 ...

Detection of DNA-RNA hybrids in vivo
(Humana Press Inc., 2018)
DNA-RNA hybrids form naturally during essential cellular functions such as transcription and replication. However, they may be an important source of genome instability, a hallmark of cancer and genetic diseases. Detection ...

Gene gating at nuclear pores prevents the formation of R loops
(Taylor and Francis Ltd., 2018)
Transcription is an important source of genetic variability. A large amount of transcription-associated genome variation arises from the unscheduled formation of R loops. We have recently found that physical proximity of ...
