Principal Investigator

Lea Harrington

Telomere Length Homeostasis and Genomic Instability

Lea Harrington established her laboratory in 1995, and after obtaining a professorship at the University of Toronto and subsequently at the University of Edinburgh in the field of telomere and genomic instability, she was recruited to the Université de Montréal as a professor in the Faculty of Medicine.

For her contributions to cancer research, Dr. Harrington has received a Terry Fox Young Investigator Award and an International Scholar Award from the Howard Hughes Medical Institute. Since 2017, she has been the Editor-in-Chief of the Basic Science of Oncology Clinical Teaching Manual, 6th Edition (McGraw-Hill) and Co-Chair of the Medical Review Panel for the Gairdner Foundation.

Telomere Length Homeostasis and Genomic Instability

Lea Harrington’s team seeks to demystify the mechanisms underlying telomere maintenance and fidelity. It is particularly interested in the enzyme called telomerase (TERT: telomerase reverse transcriptase), and its dosage sensitivity to factors that act to protect telomeres and genome integrity.

    Genome-wide screens reveal that resveratrol induces replicative stress in human cells

    Resveratrol (RSV) is a natural compound found in many plants, including the skin of grapes (and in wine), blueberries, raspberries, mulberries and peanuts. It has attracted considerable research attention due to its reported beneficial properties in experimental models such as yeasts, nematode worms, fruit flies and mice, including lifespan extension under certain conditions. A causal role of RSV in human health has not yet been established.
