Dr. Chantal Autexier
Senior Investigator, Lady Davis Institute, Jewish General Hospital
Professor of Anatomy and Cell Biology, and of Medicine, McGill University
Chercheur national of the Fonds de recherche Québec - Santé

Dr. Autexier obtained her Ph.D. from the Microbiology and Immunology Department at McGill University in 1991 and pursued postdoctoral training with Carol W. Greider at Cold Spring Harbor Laboratory in New York from 1991 to 1996. She is best known for her studies identifying and characterizing essential determinants of telomerase function (Autexier, C. and Lue, N.F. 2006. The structure and function of telomerase reverse transcriptase. Annual Review of Biochemistry, 75, 493-517). Her current research team is actively pursuing the identification and characterization of mechanisms that regulate telomerase and telomere function, and cell survival, with the long term objective to develop anti-cancer therapies that target telomerase or telomeres. She is co-organizer of the Canadian Symposiums on Telomeres and Genome Integrity.

Major Research Activities

The long-term objective of Dr. Autexier’s research is the development of anti-cancer therapies that target telomerase or telomere function.

Her research team’s short-term objectives are to: 1) identify and characterize the mechanisms that regulate telomerase and telomere function; and 2) evaluate the principles of anti-cancer strategies that target telomerase or telomere function.

Dr. Chantal Autexier is an internationally recognized scientist in the field of structure and function of telomerase.

Her research focus is the identification and characterization of unique determinants of telomerase and telomere function.

The aim of her research is to identify and characterize specific and essential mechanisms regulating telomerase and telomere function in telomere maintenance, cellular immortalization and cancer that can be validated as specific and effective therapeutic targets in tumor cells.
