The findings shed light on how the brain orients itself in changing environments – and even the processes that can go wrong with degenerative diseases like dementia, that leave people feeling lost and confused.</p> Wed, 22 Mar 2023 16:03:43 +0000 webfull 188415 at /channels /channels/channels/news/fighting-brain-cancer-its-root-332868 <p>Æ»¹ûÒùÔº researchers identify proteins that drive cancer stem cells. Targeting and supressing a particular protein called galectin1 could provide a more effective treatment for glioblastoma, in combination with radiation therapy.</p> <p>Due to its resistance to therapy, glioblastoma is the most common and aggressive cancerous brain tumour in adults. It grows fast and spreads quickly. While treatments such as surgery, radiation, and chemotherapy can help ease symptoms for a few months, in most cases tumour cells regrow after treatment and the cancer recurs.</p> Tue, 31 Aug 2021 15:10:36 +0000 webfull 172657 at /channels /channels/channels/news/new-use-old-drug-how-does-ketamine-combat-depression-327092 <p>A group of proteins called 4E-BPs, involved in memory formation, is the key to unlocking the antidepressant effect of ketamine in the brain, according to researchers from three Canadian universities.

Researchers have long been searching for ways to treat Glioblastomas – the most stubborn type of brain tumour – as they’re well known for their resistance to treatment. A few years back, they were able to confirm the key role a gene called the OSMR gene plays in the process of brain cancer growth.</p> Thu, 20 Aug 2020 19:41:21 +0000 webfull 162624 at /channels /channels/channels/news/gene-targeting-helps-overcome-resistance-brain-cancer-therapy-323716 <p>New insight into a gene that controls energy production in cancer stem cells could help in the search for a more effective treatment for glioblastoma. A Æ»¹ûÒùÔº-led study published in <i>Nature Communications</i> reveals that suppressing the OSMR gene can improve the effectiveness of radiation therapy.</p> <p>This approach, led by the laboratory of Arezu Jahani-Asl, Assistant Professor of Medicine at Æ»¹ûÒùÔº, was successful in preclinical mouse models where the deletion of the OSMR gene resulted in a significant improvement of tumour response to therapy and expanded lifespan.</p> Mon, 17 Aug 2020 13:12:58 +0000 webfull 162510 at /channels /channels/channels/news/healthy-brains-healthy-lives-launches-hbhl-neuro-innovation-fund-286136 <p>The Healthy Brains for Healthy Lives (<a href="//www.mcgill.ca/hbhl/">HBHL</a>) initiative is happy to announce the launch of its Neuro-Innovation Fund.
