Amélie Marais

Amélie Marais’ research looks at a specific type of muscular dystrophy called Duchenne Muscular Dystrophy (DMD).

Here is some background on DMD:

  • Boys with DMD end up experiencing a “typo” in their genes that makes it so they’re missing one of the really important structural proteins in their muscles.
  • Overtime they cannot build up their muscles which results in them losing a lot of it.
  • Because of this, DMD patients live a shortened lifespan.
  • Current treatment options are not good, as the drugs currently available have very negative side effects.

That is where Amélie comes in – her research involves trying to find better ways to treat the disease and one of those ways is by targeting a specific protein, GSK-3. Her research has been showing very promising results, and she hopes treatment to block GSK-3 could be a treatment option for DMD patients. Why is this important? Amélie shares that we are letting DMD patients down and there is not a good understanding of how to treat this disease. Amélie knows she has a responsibility and resources to do this research, by looking into better treatment options to help individuals be stronger for longer, help their families, and reduce any stresses on the healthcare they might experience.

Jessica Braun

How does muscle health affect metabolism? Jessica Braun’s research investigates the function of a protein found in skeletal muscle and heart muscle and how it affects function as well as metabolism! Why is this important?! This protein has not been looked at before, and we need to characterize it well so it can be used in future research with regards to muscle health, aging, muscle dystrophy, and unloading.

Luc Wasilewicz

Luc Wasilewicz studies Duchenne Muscular Dystrophy, a muscle wasting disease, but the issue he found with current research is most of it has been done at room temperature. For mice, this represents a cold stress and induces physiological changes, which affects results. Luc addresses this issue by housing mice at a temperature that is more physiologically relevant for research. 

 We call this temperature zone thermoneutral, but you can think about it like a Goldilocks zone – the temperature zone that is just right so you don’t have different metabolic changes that could be occurring and alter their physiology, and then alter how the research is interpreted. 

Why is this important to research? Think of this research as fact checking; increasing the accuracy of future research and highlighting the importance of housing temperature for interpreting results. The goal of his research is to provide insights into mechanisms of muscle wasting and test therapeutic options to treat Duchenne Muscular Dystrophy. 

Sophie Hamstra

Heart failure, lithium, and calcium movement …. what do we need to know about this? Well, muscles need controlled calcium movement in their cells and in Sophie Hamstra’s research, she is focused on trying to prevent heart failure by maintaining that calcium movement. Why? Sophie has always been interested in cardiovascular function and being a part of the health science field. Taking a chance at the opportunity to do new research allowed her to become part of this project and make important strides forward in this area of study.
