Cell biology of disease

Our laboratory aims to provide new insight into cellular and molecular mechanisms underlying severe pathological conditions to promote/develop innovative therapeutic strategies. We focus on the RNA life cycle and its critical regulators, such as SMN protein. We are interested to understand how plasma membrane subdomains influence the RNA fate, in particular the mRNA traffic and local translation. We use a multi-disciplinary approach including cell imaging and biochemical methods to characterize novel RNA-protein interactions, subcellular localizations of selected RNA, and molecular networks associated to organelle/cellular compartments. We have a long-standing interest in neuromuscular disease, such as Duchenne Muscular Dystrophin (DMD) and Spinal Muscular Atrophy (SMA). We recently developed translational studies focusing on head and neck squamous cell carcinoma (HNSCC) to identify oncogenic molecular signature as well as novel drug targets.
