About

I obtained my first level degree in Biology (specializing in Biotechnology) in 2013 at the University of Barcelona. Then I obtained a Master degree in Neuroscience defending the thesis “Neuropsychiatric synthoms on dementias” at the European University Miguel de Cervantes, in Madrid. On 2015 I reached a Master degree in Genetics and Genomics at the University of Barcelona, defending the thesis “Identification of lncRNAs acting as competing endogenous RNAs (ceRNAs) in breast cancer cells”, an experimental work realized during a 6 month stage at the Bioindustry Park in Ivrea, Italy. In 2015 I joined the University of Torino, Dept. of Clinical and Biological Sciences in Orbassano, with a PhD fellowship (PhD School in Life and Health Sciences). I obtained my PhD on May 9 th 2019 defending the thesis “Luminal breast cancer circRNAs uncovered by a novel tool for data analysis”. The multidisciplinary background obtained from the PhD program in Complex Systems for life Sciences gave me the opportunity to study biological problems by using combined computational and experimental approaches. Currently, I have a Postdoc research fellowship in Milan, in Center for Genomic Science of IIT@SEMM, Istituto Italiano di Tecnologia.

  • N6-Methyladenosine mediates drug resistance of human Hepatocellular Carcinoma

    Although dysregulation of m6A methylation has been reported in many human cancers, its role in cancer drug resistance is still unclear. Recent studies have enlightened the importance of the epitranscriptome on Hepatocellular carcinoma (HCC) and various m6A effectors seem to be involved in HCC progression development. Furthermore, in a recent study, some of these m6A effectors have been associated with drug resistance or sensitivity.

     We hypnotize that we may revert cell resistance to the drugs by altering the fate of modified RNAs through perturbation of specific m6A effectors. We want to investigate whether m6A-dependent alterations of the RNA metabolism are central in the drug resistance. And, since some of these drugs interfere with the action of RNA Polymerase II (RNAPII) we want to unravel the role of the interplay between RNAPII and m6A epitranscriptome.

    This research has the potential to reveal an unexpected role for the modifications of RNA in the context of HCC drug resistance. Moreover, the data generated by cutting edge genomics approaches will allow to closely test the involvement of specific molecular mechanisms, through which epitranscriptional alterations results in HCC aberrant transcriptional programs.

    The epitranscriptome is emerging as a novel possible druggable target in cancer. However, we still have a limited knowledge on the functional role of this layer of regulation. Our results are expected to reveal previously unanticipated functional consequences of epitranscriptional alterations, which could disclose novel therapeutic targets and mechanisms for HCC diagnosis and treatment.

  • Characterization of the interplay between RNAPII and m6A

    A few recent studies have suggested that the establishment of m6A patterns occurs in the early phases of transcription and could be coupled with the transcriptional machinery. RNAPII is a key factor in genes’ transcription and a complex regulatory hub that could profoundly affect and be affected by the m6A epitranscriptome. We have an in house tool able to de-convolute the different RNAPII life cycle steps by computational modelling. We will quantify epitranscriptional dynamics and profile the binding of the RNAPII complex by ChIP-seq using different drugs that cause an acute perturbation of the RNAPII life cycle. The analysis of the effects of these drugs over time in the context of mESCs with METTL3 KD will allow us interfering with crucial phases of the RNAPII life cycle, and will stress the system to reveal how the phases are effected by the lack of m6A.
