DNA-RNA hybrids: The risks of DNA breakage during transcription
(Springer Nature, 2017)
Although R loops can occur at different genomic locations, the factors that determine their formation and frequency remain unclear. Emerging evidence indicates that DNA breaks stimulate DNA-RNA hybrid formation. Here, we ...

Targeting the centriolar replication factor STIL synergizes with DNA damaging agents for treatment of ovarian cancer
(Impact Journals, 2017)
Advanced ovarian cancer is an incurable disease. Thus, novel therapies are required. We wished to identify new therapeutic targets for ovarian cancer. ShRNA screen performed in 42 ovarian cancer cell lines identified the ...

267 Spanish Exomes Reveal Population-Specific Differences in Disease-Related Genetic Variation
(Oxford University Press, 2016)
Recent results from large-scale genomic projects suggest that allele frequencies, which are highly relevant for medical purposes, differ considerably across different populations. The need for a detailed catalog of local ...

Nuclear Envelope Integrity in Health and Disease: Consequences on Genome Instability and Inflammation
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
The dynamic nature of the nuclear envelope (NE) is often underestimated. The NE protects, regulates, and organizes the eukaryote genome and adapts to epigenetic changes and to its environment. The NE morphology is characterized ...

Immune signaling kinases in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD)
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Amyotrophic lateral sclerosis (ALS) is the most common neurodegenerative disorder of motor neurons in adults, with a median survival of 3–5 years after appearance of symptoms, and with no curative treatment currently ...

Histone deacetylases facilitate the accurate repair of broken forks
(Taylor & Francis, 2020)
We have recently uncovered that loss of the yeast histone deacetylases Rpd3 (Reduced Potassium Dependency 3) and Hda1 (Histone DeAcetylase 3) affects the cohesion between sister chromatids thus impairing repair of DNA ...

Chd7 is indispensable for mammalian brain development through activation of a neuronal differentiation programme
(Nature Publishing Group, 2017)
Mutations in chromatin modifier genes are frequently associated with neurodevelopmental diseases. We herein demonstrate that the chromodomain helicase DNA-binding protein 7 (Chd7), frequently associated with CHARGE syndrome, ...

Control genético de las deleciones entre secuencias repetidas directas en Saccaromyces cerevisiae
(1996)
Los genomios de todos los organismos están constituidos por un número variable de secuencias repetidas, que pueden llegar a suponer el 50% del DNA total. Los fragmentos de DNA repetido pueden interactuar entre si de muy ...

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 ...

Population Genetic Structure of the Grasshopper Eyprepocnemis plorans in the South and East of the Iberian Peninsula
(Public Library of Science, 2013)
The grasshopper Eyprepocnemis plorans subsp. plorans harbors a very widespread polymorphism for supernumerary (B) chromosomes which appear to have arisen recently. These chromosomes behave as genomic parasites because they ...
