Research projects
"RNA and genome stability” funded by MIUR (PRIN 2017) : Transcription can be a source of genome instability, especially through the formation of DNA:RNA hybrids intermediates. Importantly, RNA and its potential to form a hybrid with single-stranded DNA is now emerging as key positive regulator of the pathways maintaining genome stability too. Therefore, the study of the emerging role of RNA both as threat and a guardian of genome stability is extremely important. Our aim is to investigate the mechanisms leading to DNA:RNA hybrid formation and those preventing their formation, under physiological and pathological conditions, using the yeast Saccharomyces cerevisiae and mammalian cells as model systems.
