Functional Genomics and Noncoding RNAs

Under the direction of Martin Sauvageau

Research Unit

Efforts to understand the genetic and molecular interactions contributing to the development and progression of diseases have focused mostly on protein coding genes, leaving the noncoding genome vastly under-explored. It is known that a large fraction of these noncoding regions are transcribed, generating thousands of long RNAs that do not encode proteins (lncRNAs). These lncRNAs are expressed with exquisite tissue specificity and several have been found to regulate diverse regulatory processes. Accumulating evidence also point to lncRNA loci as risk factors frequently deregulated or mutated in a wide variety of human diseases. However, whether lncRNAs contribute to the establishment or progression of diseases in vivo and how they may affect transcriptional programs and signaling pathways still remains poorly characterized. Thus, one of the main challenge to understand the noncoding genome’s influence on human health is not only to determine which lncRNAs are functional, but also to decipher how they perform their tasks and affect the pathophysiology of diseases.
 
The Research Unit takes advantage of human genetics data to identify lncRNAs in disease risk genomic regions. Members of the team combine genetically engineered mouse 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. They also aim to uncover novel noncoding RNA-based mechanisms by characterizing the molecular interactions and regulatory principles underlying the function of lncRNAs. For this, they use a combination of biochemistry, genome editing, computational and high-throughput genomics approaches to identify interacting proteins and understand how specific domains or RNA sequences within lncRNAs mediate their function.
 
The laboratory's goal is to better understand the impact that lncRNAs and noncoding regions have on human health and diseases and provide much needed genetics and molecular bases towards the development of novel diagnostics and RNA-targeting therapeutics.
