Research Area: Muscle Biology and Pathology
Keywords: muscle biopathology, nocoding RNAs, gene therapy
Our research group has a wide long-standing experience in molecular and cellular biology of muscle cells, intracellular cell signaling in oncogenic transformation and differentiation, and post-transcriptional regulation of gene expression, particularly microRNA analysis and studies on microRNA-target interaction.
In past years our research has focused on the role of noncoding RNAs in normal muscle differentiation and in disease. Thanks to the development of a method to select and identify the functionally active microRNAs and their target mRNAs, we have identified some crucial microRNAs involved in normal muscle differentiation and in muscular dystrophies, particularly in Myotonic Dystrophy type 1 (DM1). In addition to microRNAs, we have also identified circular RNAs specifically upregulated in DM1. Both classes of noncoding RNAs are most likely involved in DM1 pathogenetic mechanisms and can be used as disease biomarkers. Functional characterization of DM1-related microRNAs and circular RNAs is a topic of ongoing research in our group.
DM1 is a dominantly inherited multisystemic disorder and the most common form of muscular dystrophy in adults. Especially in the most severe forms, life expectancy and quality in DM1 affected individuals are seriously compromised. The disease is caused by expanded CTG repeats in the 3’ untranslated region (3’UTR) of the DMPK gene. No effective therapy is yet available for DM1. Very recently, we have developed a CRISPR/Cas9-mediated genome editing approach for permanent deletion of pathogenetic repeats, using cell models ad hoc generated from DM1 patients’ biopsies. By using this strategy, we obtained a time-controlled and target-specific gene editing, and succeeded in reversing the pathologic phenotype of DM1 cells. We are now applying this gene editing approach to a mouse model of DM1 with the ultimate goal to obtain the reversal of the diseased phenotype, opening the way for future gene therapy application in humans.
