From humans to fruit flies, they play a unique role in the growth of cancerous tumours and the spread of cancer throughout the body. New research emerging from 91社区 is contributing to what is known about PRLs, which could potentially become an important tool in the development of cancer-fighting treatments.聽聽</p> Mon, 15 May 2023 14:39:22 +0000 frederique.mazerolle@mcgill.ca 300187 at /newsroom /newsroom/channels/news/what-makes-certain-groups-more-vulnerable-covid-19-326681 <p>What makes the elderly and people with underlying conditions more vulnerable to COVID-19? According to a new <a href="https://doi.org/10.1016/j.csbj.2020.11.016">study</a> led by 91社区 researchers, clues can be found in the proteins involved in initiating infection, as the virus binds to host cells of different animals. Greater cellular oxidation with aging and sickness may explain why seniors and people with chronic illness get infected more often and more severely.</p> Thu, 03 Dec 2020 02:59:17 +0000 shirley.cardenas@mcgill.ca 251893 at /newsroom /newsroom/channels/news/new-technique-nets-scientists-haul-key-proteins-303862 <p>Using a new microscopic "fishing" technique, scientists from the Montreal Clinical Research Institute (IRCM), Universit茅 de Montr茅al and 91社区 have successfully snagged thousands of proteins that play a key role in the formation of the cell skeletons or cytoskeletons. Cell skeletons, whose primary function is to give the cells their shapes, are also involved in things like muscle contraction. They are made up of an interlocking network of protein filaments that connect the cell nucleus to the cell membrane.</p> Tue, 07 Jan 2020 12:07:32 +0000 amelia.souffrant@mail.mcgill.ca 195047 at /newsroom /newsroom/roderick-r-mcinnes Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 24036 at /newsroom /newsroom/john-presley Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 23624 at /newsroom
