Marc Therrien is a principal investigator at the Institute for Research in Immunology and Cancer (IRIC) and holds the Canada Research Chair in Intracellular Signalling. With his team, he devotes his research to the study of the signalling mechanisms involved in cellular differentiation and cellular division.
After completing his Ph.D. in Biochemistry at the Université de Montréal, Marc Therrien wanted to develop a greater understanding of the intracellular signalling process using drosophilia. He considers this multi-cellular organism, which he still uses today, to be a highly effective model to explore fundamental questions in biology, the answers to which can then be used in the study of human biology.
Thus, he went on to do his postdoctoral training at the University of California at Berkeley. His work there focused on how cells perceive extra-cellular signals and how these signals are then sent to different sites in the cell to stimulate a response. The research group Marc Therrien belonged to identified several genes that function in concert with RAS, a notorious oncogene. The group also noted that the network which allows a cell to receive signals is far more complex than ever anticipated.
In 1999, Marc Therrien returned to Quebec to set up his laboratory at the
l’Institut de recherches cliniques de Montréal. In 2003, he joined IRIC as one of its founding principal investigators. The team he leads at IRIC continues its work on how signals are transmitted from one molecule to another, specifically in the RAS signalling pathway. The group is also interested in pathways parallel to the RAS pathway, namely one that allows cells to adhere to one another. It is already known that cancer cells become metastatic, in other words that they loose their adhesion capability. Dr. Therrien and his group seek to understand how the signalling pathway that controls cell adhesion communicates with the RAS pathway, which controls cellular proliferation.
