Project Summary:

Tommy Alain - 2017 Research Grant Recipient

Brain tumours, particularly glioblastoma multiforme, have limited therapeutic options. New therapies are needed against this almost universally fatal cancer. 

In recent years, scientists have developed approaches that involve the use of common viruses to reactivate the immune system within patients to enable it to recognize and eliminate cancer cells. 

In our laboratory, we are testing the ability of the herpes simplex virus (HSV1) to infect various cancer cell types. Recently, we have identified a chemical anti-cancer agent that dramatically enhances the ability of the virus to propagate inside brain cancer cells but not inside normal cells. 

In this study, we propose to investigate how this agent works to promote the replication of this virus. Understanding this process we believe will provide valuable insight for the development of HSV1-based anti-cancer therapeutics.

Project Update:

Oncolytic viruses are unique immunotherapeutic agents for the treatment of cancer, but their replication within tumour tissue is limited. We have discovered a novel drug that strongly boost oncolytic virus replication within cancer cells. We proposed to study the mechanism of action of this molecule and how this pharmaco-viral combination could improve murine models of brain cancer. We have found that administering this drug to tumour bearing mice prior to injection with oncolytic viruses resulted in a dramatic increase in viral spread within tumour tissues. We now are studying these processes carefully both in brain cancer cell lines and murine models of glioblastoma. Read more from this project update...

Aaron's Story: I refuse to sink

In the summer of 2017, while at work, I had my first episode of what I would now call vertigo or double vision. It was something I've never experienced before. Everything in front of me seemed to sink into the ground, my hands moving in super slow motion. It lasted about for a good 30 seconds before everything went back to normal. I brushed it off and continued on with the day.
