A large fraction of mammalian genomes is transcribed, generating tens of thousands of long RNAs devoid of protein coding potential (lncRNAs). These lncRNAs are expressed with exquisite tissue specificity and several were found to regulate key cellular processes. Evidence also points to lncRNA loci as risk factors frequently deregulated or mutated in a wide variety of human diseases. However, the extent to which lncRNAs contribute to development in vivo and how they affect transcriptional programs and signaling pathways remains poorly characterized. Thus, one of the main challenges to understand the noncoding genome’s influence on the fundamental mechanisms of life is not only to determine which lncRNAs are functional, but also decipher how they perform their tasks.
 
Our laboratory combines genetically engineered animal models and human cellular systems with functional genomics and CRISPR-based genome editing techniques to perturb lncRNA functions and characterize their role at a cellular and physiological level. We also aim to understand the molecular grammar that underlies lncRNA function and uncover novel noncoding RNA-based mechanisms. For this, we use a combination of biochemistry, high-throughput, and computational approaches to identify lncRNA-interacting macromolecules, structured lncRNA domains, and decipher their molecular grammar.

Our team also works closely with the IRCM RNA Therapeutics Core and is actively involved in developing novel RNA therapeutics of different modalities (ASO, siRNA, mRNA-LNP).

Our goal is to better understand the impact lncRNAs have on development and diseases and harness their potential as novel targets to develop RNA therapeutics.
