Chemotherapy works by essentially poisoning cancer cells, which grow more quickly than most normal cells, and thus absorb a lot of the toxic drugs. It has been regarded as a standard treatment in cancer care for decades, and can work wonders, especially early in a person’s treatment. But over time, these drugs may stop working. Dr. Catherine O’Brien and her team at the Princess Margaret Cancer Centre were trying to figure out how cancer cells apparently become resistant to chemotherapy when they made the discovery that the cells can enter a state akin to hibernation to avoid the toxic onslaught of the drugs. In this episode of the Behind the Breakthrough, Dr O’Brien discusses how her team made this groundbreaking discovery and how it may lead to unique therapeutic opportunities for patients in the future. She also discusses the importance of making connections between different scientific disciplines, and how a Grade 10 career day spent with a female surgeon inspired her to pursue a career in surgery herself.

It was Canada’s worst fear in March 2020—CoVID-19 reached the great white north. With increasing case counts and hospital burden throughout the country and in Ontario, government officials were looking to lean on healthcare economists to predict the impact of the pandemic. Dr. Beate Sander’s research highlights the importance of epidemiological modelling and how it guided public policy in Ontario. With the ever-changing data from around the world, her team highlighted the importance of certain measures to stop the spread. She discusses how the pandemic affects certain populations disproportionally. Plus, she expresses the need for better public data infrastructures, reporting, tracking and analytics to be well prepared in the future.

Dr. John Dick is known internationally for his discovery of blood stem cells. His work has broadened understanding of where and why leukemia starts, and what we could do to prevent it. In this episode of Behind the Breakthrough, Dr. John Dick takes us behind the scenes on his career, building on the pioneering work of Drs. James Till and Ernest McCulloch—the first to define the properties of stem cells. He delves into the pivotal moments that led to discoveries that have changed the face of cancer research, and why science doesn’t happen in a vacuum. Read more at www.behindthebreakthrough.ca.

Almost 20 years ago, a hallway conversation kickstarted Dr. Mansoor Husain’s journey in helping create and test a new diabetes drug that reduces the risk of heart disease. In 2019, the award-winning physician-scientist at the Ted Rogers Centre for Heart Research and Peter Munk Cardiac Centre published the findings of a landmark trial proving the drug’s safety and reduction in cardiovascular-related mortality, bringing a new therapy into the fold for patients with diabetes – who are two to four times more likely to die from cardiovascular problems than those without it.  In this episode of Behind the Breakthrough, Dr. Husain brings the listener into his lab, where he aims to understand more about the molecular mechanisms behind heart disease. He shares how a Nylon experiment in a high school chemistry class sparked his love for science and ultimately led him to medical school, and what keeps him motivated after 25 years as a scientist.  “I believe that being in the clinic makes a better scientist, and being in the lab makes me a better doctor.”

The stories patients and caregivers tell of the difficulties managing day-to-day tasks stay top of mind for Dr. Alex Mihailidis, an award-winning scientist developing smart home systems to care for and promote the wellbeing of older adults. From robots who support common household activities, floor tiles that monitor blood pressure and sensors that can send a reminder to turn off the stove, Dr. Mihailidis is alleviating the responsibility of care from the patient and caregiver and putting it into the home.  On this episode of Behind the Breakthrough, Dr. Mihailidis journeys through his years of research into smart home technology, with early innovations such as ‘Ed the Robot’ and his current role as Scientific Director of the AGE-WELL Network of Centres of Excellence. Dr. Mihailidis also tells the story of how he became a patient at the Toronto Rehab Institute, the hospital where he works, after surviving a 30 foot fall down a cliff. Having to regain his ability to walk and perform daily functions, the tragic event taught him the importance of integrating his research with clinical practice.  “If we can come up with a solution through technology that can help ease the issues older people face, even just a little bit, and make it better not just for the person but the family that supports them...then that’s why I continue to do this.”

In 2007, Dr. Ralph DaCosta was in the Princess Margaret Optics Lab researching molecular imaging to better visualize cancer when he made a serendipitous discovery that could revolutionize wound care. Hear about his groundbreaking work in visualizing cancer, his serendipitous discovery that has turned him into an inventor and entrepreneur, and how Terry Fox was the inspiration for his drive to enter cancer research.   In his early career he was awarded the Terry Fox Research Foundation’s New Innovator Grant. “I immediately went back to 1980 watching Terry Fox…to come full circle with that is very personally meaningful to me,” he says. Listen to hear about his career path, what it was like to immigrate to Canada at the age of 6, and more.

What attracted Dr. Sonya MacParland to the world of science was the possibility of making a discovery no one else has ever made. It’s exactly what she went on to do – the award-winning scientist at UHN’s Toronto General Hospital Research Institute developed the world’s first transcriptomic map of the liver, triggering a paradigm shift in liver research and therapy.   On this episode of Behind the Breakthrough, Dr. MacParland takes the listener through the intricacies of the only organ in the human body with the ability to regenerate itself - the liver. She explains how she and her team mapped the thousands of cells within it, and why they felt it was integral to keep the research open-access for scientists around the world to use as a guide. Dr. MacParland also dives into the personal side of her success as a scientist, sharing how she deals with the failures and pressures of her work and the role mentorship plays in a successful career.  “Being able to do science and discover together on a daily basis is a gift,” says Dr. MacParland. “The fact that I'm able to do this and work with brilliant students, brilliant scientists and wonderful patients is just so fulfilling.”

Hand trauma sends more Canadians to the emergency room each year than any other injury, something this episode’s guest refers to as an “unrecognized public health issue.’ Dr. Heather Baltzer joins us to discuss her pioneering research to improve both the treatment and outcomes for people suffering hand trauma, as well as the effect such traumas can have on both the patient and the healthcare system at large. Dr. Baltzer also discusses the importance of mentorship, the role of serendipity in research and recreating The New Yorker Magazine cover depicting an all-female surgical team that turned into a rallying cry for women surgeons around the world.
