According to a news release from Western University on Monday, a team of researchers, led by Dr. Michael Strong, have discovered a potential path toward a cure for amyotrophic lateral sclerosis, also known as ALS. "As a doctor, it's been so important for me to be able to sit down with a patient or their family and say to them, 'We're trying to stop this disease,'" said Strong, Arthur J Hudson Chair in ALS research at Western's Schulich School of Medicine & Dentistry. The discovery Published in the journal Brain, Strong's team discovered that targeting an interaction between two proteins present in ALS-impacted nerve cells can halt or even fully reverse the progression of the disease. "Importantly, this interaction could be key to unlocking a treatment not just for ALS but also for other related neurological conditions, like frontotemporal dementia," said Strong. "It is a game changer." According to the study, in nearly all ALS patients, a protein called TDP-43 is responsible for forming abnormal clumps within cells, which causes cell death. In recent years, Strong's team discovered a second protein, called RGNEF, with functions that are opposite to TDP-43. The team's research identified a specific fragment of the RGNEF protein -- named NF242 -- that can "mitigate the toxic effects of the ALS-causing protein." As a result, the researchers discovered that when the two proteins interact with each other, the toxicity of the ALS-causing protein is removed, which significantly reduces damage to the nerve cell and therefore prevents its death. After 30 years of his life working on ALS research with various teams, Strong is confident in what the future holds as a result of the new discovery not just for the treatment of ALS, but for other neurodegenerative diseases. "I think we can reasonably look at this and say, 'This is swinging for the bleachers,' we think in three to five years, we might be looking at something [ALS] that might be cured," said Strong. "We can, in an experimental model, significantly either completely abolish the [ALS] disease process. Or, in another one do a significant job of slowing it down and changing the course of the disease."

(Sean Irvine/CTV News London) How researchers got here The light bulb moment in Strong's research came seven years ago when the team was working with fruit flies. Flies that were genetically modified to have the pathology of ALS died within 10 to 14 days, whereas a fly typically has a lifecycle of 70 to 80 days. Those flies with the new pathway Strong said had a longer lifespan, improved motor functions and their nerve cells were protected from degeneration. The next step in research was using mice, where a mouse named Lucy who had been genetically modified to have ALS was given both treatments. Her sister did not receive the treatment and died, whereas Lucy lived through experimentation and according to Strong was "doing fine." "Best results I've ever seen from an animal model," he said. What is ALS? Also known as Lou Gehrig's disease, ALS is a debilitating neurodegenerative condition that progressively impairs nerve cells responsible for muscle control, leading to muscle wastage, paralysis and death, according to Western. The average life expectancy of an ALS patient post-diagnosis is two to five years. Due to the complex nature of the disease, there are no effective forms of therapy that can prevent its progression.

(Sean Irvine/CTV News London) A 'gift' for ALS research The announcement was made ahead of ALS Awareness Month in Canada. Also included in Monday's announcement was a $10 million donation over the next five years from the Temerty Foundation. Established by Jim Temerty, founder of Northland Power Inc., and Louise Arcand Temerty, the funding will help with the next steps of bringing the newfound treatment to ALS patients. "Finding an effective treatment for ALS would mean so much to people living with this terrible disease and to their loved ones," said James Temerty. "Western is pushing the frontiers of ALS knowledge, and we are excited for the opportunity to contribute to the next phase of this groundbreaking research." Strong and his team have set a goal to bring their potential treatment to human clinical trials within the next three to five years, "a mission that is fueled by the new gift from the Temerty Foundation," Western said. Strong is very cautionary, but if things progress he expects a "cure" is not far off. "It's been 30 years of work to get here; 30 years of looking after families and patients and their loved ones, when all we had was hope. This gives us reason to believe we've discovered a path to treatment," he said. -- With files from CTV News London's Sean Irvine London Top Stories * [image] Victim loses $2M in online romance scam * [image] Commercial vehicle hits Talbot Street rail overpass * [image] Wingham, Ont. loses its 'biggest star' as Alice Munro passes at 92 * [image] Section of Highbury Avenue to close Wednesday for infrastructure maintenance * [image] SUV tumbles down steep embankment near Highway 401 * [image] Grand opening for new Northwest London Resource Centre * [image] Contractor recounts frantic moments during fatal London, Ont. fire * [image] Lawyers for former Canada World Junior hockey players facing sex assault charges make brief court appearance, case back in court in June CTVNews.ca Top Stories [image] 'Most of the city is evacuating': Gridlock on Alberta highway after evacuation order in Fort McMurray Four Fort McMurray neighbourhoods were ordered to evacuate on Tuesday as a wildfire gets closer to the city.
