My research group has an established expertise in the study of post-transcriptional gene regulation in eukaryotes. In this regard, we are presently exploring the role of noncoding RNAs (microRNAs, long noncoding RNAs and circular RNAs) as regulative molecules in neuronal differentiation and studying their deregulation in neurological disorders, such as brain tumours (medulloblastoma and glioblastoma) and neurodegeneration (Amyotrophic Lateral Sclerosis-ALS).

The main research projects, we are currently involved in, concern:

1)  Identification and functional characterisation of novel long noncoding RNAs (lncRNAs) instructing neuronal differentiation programs and implicated in tumorigenesis (medulloblastoma and glioblastoma).
lncRNAs, that include also circular RNAs, are very versatile transcripts that may regulate gene expression at multiple levels, from epigenetic to transcriptional and post-transcriptional ones. We are particularly interested in determining which non-coding RNAs are important for early and late differentiation events and in understanding how these RNAs control gene expression, which are their target genes and their mechanism of action. This ultimately allow us to build RNA-based regulatory circuitries relevant for normal neuronal physiology and possibly deranged in neurological tumours.


2)    Characterisation of the noncoding transcriptome (including microRNAs, long noncoding RNAs and circular RNAs) in a FUS-ALS model, to decipher how the noncoding RNAs contribute to the ALS pathology and if their action can be reversed.  
The protein FUS widely controls RNA metabolism making ALS an RNA disorder: for our aim, we use in vitro-derived mouse motor neurons (MNs), the neuronal subtype primarily affected in ALS, carrying one of the most severe ALS-associated FUS mutations. We found specific classes of microRNAs, long noncoding RNAs and circular RNAs, which are specifically affected by the mutated version of FUS, both in terms of biogenesis and/or expression, highlighting a role for these transcripts in ALS. 


3)     Functional characterisation of endoribonucleases involved in coding and non-coding RNA metabolism.

We discovered the founding member of the Eukaryotic EndoU ribonuclease family, whose components are flexibly involved in important biological processes, such as ribosome biogenesis, tumorigenesis and viral replication. Upon characterization of the amphibian and human homologs, we are focusing on the Drosophila enzyme that we revealed to be essential for nervous system activity and to act as a positive regulator of the neurodegeneration-associated protein dTDP-43. We are analysing, by transcriptome analysis, the in vivo target repertoire of this endoribonuclease (mRNAs, miRNAs, lncRNAs, circRNAs) to determine their involvement in nervous system.

These projects are supported in the framework of Project on Life Nanoscience of Italian Institute of Technology (IIT)  and Progetto Bandiera Epigenomica (Epigen)
