This type of behaviour, where two actions are mutually exclusive, is common in many animals including humans – we cannot sit and run at the same time, for example.</p> <p>Scientists long believed that control of movements in worms was due to straightforward reciprocal actions between two neurons: AVA and AVB. The former was thought to promote backward motion while AVB facilitated forward motion, with each neuron inhibiting the other to control movement direction.</p> <p>However, the new data from Zhen’s team challenge this notion, uncovering a more complex interaction where the AVA neuron plays a dual role. It not only instantly stops forward motion by inhibiting AVB, but also maintains a longer-term stimulation of AVB to ensure a smooth transition back to forward movement.</p> <p>The discovery highlights the AVA neuron’s ability to finely control movement through distinct mechanisms, depending on different signals and across different time scales.</p> <p>“In terms of engineering, this is a very economical design,” said Zhen, who is also a professor of&nbsp;molecular genetics&nbsp;in 鶹Ƶ’s Temerty Faculty of Medicine. “The strong, robust inhibition of the backward circuit allows the animals to respond to bad environments and escape. At the same time, the controller neuron continues to put in constitutive gas into the forward circuit to generate movement towards safer places.”</p> <p><strong>Jun Meng</strong>, a former PhD student in the Zhen lab who led the research, said understanding how animals transition between such opposing motor states is crucial for insights into how animals move as well as neurological disorder research – and that the worms provide a unique window into basic neural wiring that's to their simple, see-through bodies.</p> <p>The discovery that the AVA neuron plays such a dominant role offers a major new insight into the neural circuit that scientists have studied since the inception of modern genetics over half a century ago. The Zhen lab successfully leveraged cutting-edge technology to precisely modulate the activity of individual neurons and record data from living worms in motion.</p> <p>Zhen, who is also a professor of&nbsp;cell and systems biology&nbsp;at 鶹Ƶ’s Faculty of Arts &amp; Science, emphasizes the importance of interdisciplinary collaboration in this research. Meng performed key experiments, while neuronal electrical recordings were conducted by&nbsp;<strong>Bin Yu</strong>, a PhD student in&nbsp;<strong>Shangbang Gao</strong>’s lab at Huazhong University of Science and Technology in China.</p> <p><strong>Tosif Ahamed</strong>, a former post-doctoral researcher in the Zhen lab and now a Theory Fellow at the HHMI Janelia Research Campus in the United States, led mathematical modelling efforts that were crucial for testing hypotheses and gaining the new insights.</p> <p>The findings provide a simplified model to study how neurons can manage multiple roles in movement control – a concept that might extend to human neurological conditions.</p> <p>For example, AVA’s dual role depends on its electric potential, which is regulated by ion channels on its surface. Zhen is already exploring how similar mechanisms could be involved in a rare condition known as CLIFAHDD syndrome, caused by mutations in similar ion channels. Additionally, the new findings could inform the development of more adaptable and efficient robotic systems capable of complex movements.</p> <p>“From the origin of modern science to the forefront of today’s research, model organisms like <em>C. elegans</em> have been instrumental in peeling back the layers of complexity in our biological systems," said&nbsp;<strong>Anne-Claude Gingras</strong>, director of the Lunenfeld-Tanenbaum Research Institute, vice-president of research at Sinai Health and a professor of molecular genetics in 鶹Ƶ’s Temerity Faculty of Medicine.</p> <p>“This research is a great example of how much we can learn from simple animals, to then think about applying this new knowledge to advancing medicine and technology.”</p> <p>The research was supported by the Canadian Institute of Health Research, the Natural Sciences and Engineering Research Council of Canada, the National Natural Science Foundation of China and the European Research Council.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 16 May 2024 15:01:59 +0000 Christopher.Sorensen 307873 at Remembering Yoshio Masui, renowned cell biologist and longtime 鶹Ƶ professor /news/remembering-yoshio-masui-renowned-cell-biologist-and-longtime-u-t-professor <span class="field field--name-title field--type-string field--label-hidden">Remembering Yoshio Masui, renowned cell biologist and longtime 鶹Ƶ professor</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-04/2024-006-crop.jpg?h=81d682ee&amp;itok=w269HxVy 370w, /sites/default/files/styles/news_banner_740/public/2024-04/2024-006-crop.jpg?h=81d682ee&amp;itok=lnLPgP8Q 740w, /sites/default/files/styles/news_banner_1110/public/2024-04/2024-006-crop.jpg?h=81d682ee&amp;itok=L9RBkjXe 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-04/2024-006-crop.jpg?h=81d682ee&amp;itok=w269HxVy" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>rahul.kalvapalle</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-04-26T14:20:01-04:00" title="Friday, April 26, 2024 - 14:20" class="datetime">Fri, 04/26/2024 - 14:20</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>Professor Emeritus Yoshio Masui is credited with helping make developmental biology an essential discipline (supplied image)</em></p> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/cell-and-systems-biology" hreflang="en">Cell and Systems Biology</a></div> <div class="field__item"><a href="/news/tags/faculty-arts-science" hreflang="en">Faculty of Arts &amp; Science</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">Professor Emeritus Yoshio Masui's career at 鶹Ƶ spanned more than half a century</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>The University of Toronto is <a href="https://csb.utoronto.ca/remembering-the-wisdom-and-curiosity-of-professor-yoshio-masui-1931-2024/">mourning the death of <strong>Yoshio Masui</strong></a>, a professor emeritus in the departments of zoology (1968 to 2006) and cell and systems biology (2006 to 2024) in the Faculty of Arts &amp; Science and a celebrated cell biologist who spent more than half a century at the university.&nbsp;</p> <p>Born in Kyoto, Japan in 1931, Masui earned undergraduate, master’s and doctoral degrees in Kyoto University before coming to 鶹Ƶ in 1968, driven by a desire for “freedom for research – neither interference with nor solicitation for choices of research projects”.</p> <p>Masui made several important discoveries, including revealing details on how eggs mature and uncovering clues as to how cancer can arise from uncontrolled cell growth.

The myriad of different structures enable proteins to perform their functions.

We need to know what’s common and what’s exceptional.”</p> <p>The development of this powerful and unexpected application of AlphaFold2 demonstrates the power of using AI to solve the protein folding problem and will improve researchers’ understanding of IDRs and their role in disease.</p> <p>“In the IDRs that AlphaFold2 predicts to have some structure, we’ve shown that mutations are far more likely to cause disease than mutations in other structureless IDRs,” says Moses. “This is an important advance in understanding how mutations in IDRs can cause disease, which is generally not well understood. We now believe that many of the mutations are disrupting the structure somehow.</p> <p>“What’s more, because AlphaFold2 predictions are already available for all proteins, now we can say for the first time how many IDRs across the tree of life have structure. Our paper shows that bacterial IDRs are much more likely to have structure than human and animal IDRs.

Like flipping pages in a recipe book, the DNA containing the instructions for turning genes on in the lung is open and used in the lung, for example, but closed and ignored in other types of cells.</p> <figure role="group" class="caption caption-drupal-media align-right"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/2023-10/Dr-Luis-Abatti-crop.jpg" width="300" height="400" alt="&quot;&quot;"> </div> </div> <figcaption><em>Luis Abatti (supplied image)</em></figcaption> </figure> <p>“We know that some cancer cells are opening the wrong pages in the recipe book – ones that contain the SOX2 gene, which can cause tumours to grow uncontrollably. We wanted to find out: How does the gene become expressed in cancer cells?”</p> <p>The researchers analyzed genome data to look for enhancer DNA that could activate SOX2 in cancer cells. The enhancer they found is open in many different types of patient tumours, meaning this could be a cancer enhancer active in bladder, uterus, breast and lung tumours. Unlike many cancer-causing changes, the enhancer reprogramming mechanism does not arise out of mutation due to DNA damage&nbsp;– it is caused by part of the genome opening when it should be staying closed.</p> <p>The researchers then determined that the enhancer causes increased cancer cell growth because when they removed the enhancer in lab-grown cells, the cancer cells created fewer new tumour colonies.</p> <p>To figure out why cells have a DNA region that makes cancer worse, the team examined mice without this DNA region and found they do not form a separate passage for air and food in their throat as they develop. Thus, this potentially dangerous cancer-enhancer region is likely in the human genome to regulate airway formation as the human body forms. However, if a developing cancer cell opens this region, it will form a tumour that grows faster and is more dangerous for the patient.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-10/Picture1.jpg?itok=PD4J7VdS" width="750" height="563" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>The researchers unravel the mechanism of how developmentally active enhancers become repurposed in a tumour (image:&nbsp;© Abatti et al, 2023, published by Oxford University Press on behalf of&nbsp;Nucleic Acids Research)</em></figcaption> </figure> <p>“We also found that two proteins known to have a role in the developing airways – FOXA1 and NFIB&nbsp;– are now regulating SOX2 in breast cancer,” says Mitchell, who is associate chair of research in the department of cell and systems biology and is cross-appointed to the&nbsp;department of laboratory medicine and pathobiology&nbsp;in the Temerty Faculty of Medicine.</p> <p>The enhancer is activated by the FOXA1 protein and suppressed by the NFIB protein.

Engineering have made progress in understanding the intricate cellular processes involved in tissue development and repair.</p> <p>The findings,&nbsp;<a href="https://www.sciencedirect.com/science/article/pii/S0960982223006036?dgcid=author">published in the journal&nbsp;<em>Current Biology</em></a>, shed light on the mechanisms underlying collective cell migration&nbsp;– a fundamental behaviour that plays a crucial role in both normal embryo development and pathological conditions such as cancer metastasis.</p> <p>“This study advances our understanding of the molecular signals that coordinate cellular behaviours, in embryonic development and tissue repair, and likely also in tumour invasion,” says <a href="https://csb.utoronto.ca/faculty/rodrigo-fernandez-gonzalez/"><strong>Rodrigo Fernandez-Gonzalez</strong></a>, a professor in the department of cell and systems biology and the Institute of Biomaterials and Biomedical Engineering who heads the&nbsp;<a href="https://www.quantmorph.ca/">Quantitative Morphogenesis Laboratory</a>.</p> <p>Researchers found that Rap1&nbsp;– a molecular switch that regulates cell adhesion and signalling when turned on&nbsp;– plays a role in the formation and remodelling of adherens junctions (protein complexes that occur at cell–cell junctions and cell–matrix junctions in epithelial and endothelial tissue) and the cytoskeleton during the collective cell movements that drive the rapid, scar-less wound healing response in embryos, making it an attractive therapeutic target in the future.</p> <p>In embryonic wound healing, the cells around the wound move together to seal the lesion. To that end, cells undergo a series of intricate molecular changes. At the centre of these changes, a unique structure called tricellular junction (TCJ) is formed. The TCJ acts as a hub that hosts a series of proteins that are essential in coordinating cell movements.</p> <p>When researchers tagged the Rap1 protein with a sensor that could be detected by a microscope, they were able to visualize large concentrations of the protein accumulating around the wound, and specifically at the TCJs.</p> <p>Upon establishing the localization of Rap1 in the hub of wound repair, the researchers set out to find its role in this complex process. By inactivating or reducing the amount of Rap1 in the embryo, they observed a significant reduction in the wound closure rate compared to normal embryos. Conversely, by activating Rap1, the wound closure rate was dramatically accelerated.</p> <p>“The fact that collective migration speed can be modulated by Rap1 activity provides a potential pathway for either promoting cell migration&nbsp;– for example, to heal chronic wounds or stopping undesired migration like cancer metastasis,” says <a href="https://sites.google.com/site/katherynrothenberg/"><strong>Katheryn Rothenberg</strong></a>, a postdoctoral researcher in Fernandez-Gonzalez’s lab who led the study.</p> <p>Researchers also found that Rap1 plays a crucial role in interacting with cell-cell adhesion proteins necessary to maintain cells together as they move to close the wound, and cytoskeletal proteins that cells use to pull on each other and move collectively. They observed that any disruption to Rap1 can greatly impede the speed at which wounds close.</p> <p>“By unravelling the intricate molecular mechanisms involved, we have uncovered potential targets for therapeutic interventions in various conditions that rely on collective cell migration,” Fernandez-Gonzalez says.</p> <p>“We are now keen on understanding the upstream signals that turn Rap1 on during wound healing. This understanding would facilitate the development of tools to activate Rap1 in congenital disorders associated with deficient collective cell behaviour, or to inhibit Rap1 when it contributes to spread disease.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 07 Jun 2023 20:35:11 +0000 siddiq22 301952 at From Africana development to decarbonization: 34 鶹Ƶ researchers awarded Canada Research Chairs /news/africana-development-decarbonization-34-u-t-researchers-awarded-canada-research-chairs <span class="field field--name-title field--type-string field--label-hidden">From Africana development to decarbonization: 34 鶹Ƶ researchers awarded Canada Research Chairs</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/crc-2022-group-2.jpg?h=afdc3185&amp;itok=Fxj_p-IT 370w, /sites/default/files/styles/news_banner_740/public/crc-2022-group-2.jpg?h=afdc3185&amp;itok=SmfyZ8mI 740w, /sites/default/files/styles/news_banner_1110/public/crc-2022-group-2.jpg?h=afdc3185&amp;itok=pNl_qTaO 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/crc-2022-group-2.jpg?h=afdc3185&amp;itok=Fxj_p-IT" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2022-11-16T14:01:13-05:00" title="Wednesday, November 16, 2022 - 14:01" class="datetime">Wed, 11/16/2022 - 14:01</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Scott Gray-Owen, Caroline Hossein and Marianne Hatzopoulou are three of 34 scholars at 鶹Ƶ who were awarded new or renewed Canada Research Chairs (photos by Nick Iwanyshyn, courtesy of Caroline Hossein, by Johnny Guatto)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/scott-anderson" hreflang="en">Scott Anderson</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/leah-cowen" hreflang="en">Leah Cowen</a></div> <div class="field__item"><a href="/news/tags/sunnybrook-health-sciences" hreflang="en">Sunnybrook Health Sciences</a></div> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/unity-health" hreflang="en">Unity Health</a></div> <div class="field__item"><a href="/news/tags/donnelly-centre-cellular-biomolecular-research" hreflang="en">Donnelly Centre for Cellular &amp;

Over the course of their careers, the two researchers – who are married – have attracted numerous industry partners to open science initiatives in medicine (Aled) and engineering (Elizabeth), helping establish 鶹Ƶ as a hotbed of what could be described as a new model of innovation.</p> <p style="margin-bottom:16px">Each has been made an Officer of the Order of Canada for their industry partnership work. Elizabeth <a href="https://chem-eng.utoronto.ca/news/university-professor-elizabeth-edwards-appointed-to-the-order-of-canada/#:~:text=University%20Professor%20Elizabeth%20Edwards%20(ChemE,the%20country%27s%20most%20prestigious%20honours.">received the honour</a> in 2020 for her contributions to bioremediation, while Aled was <a href="/news/u-t-faculty-alumni-and-supporters-named-order-canada-1">honoured earlier this year</a> for his efforts in advancing Canada as a leader in open science research through his leadership of the <a href="https://www.thesgc.org/">Structural Genomics Consortium (SGC)</a>, which he founded in 2003.</p> <p style="margin-bottom:16px">“Society’s big problems – such as how AI can help drug discovery, how we’re going to create bio-manufacturing capabilities that can provide medicine to the world affordably, how we’re going to tackle climate change and how we prevent the next pandemic – can’t be solved by any single actor,” says Aled, a professor in the departments of medical biophysics and molecular genetics and the Temerty Nexus Chair of Health Innovation and Technology in the Temerty Faculty of Medicine. “They require spaces to focus purely on innovation – the science, engineering and other research – in which ideas are freely shared and worries about patenting are set aside.</p> <p style="margin-bottom:16px">“We believe that universities in general, and 鶹Ƶ specifically, are ideally positioned to host these spaces.”</p> <p style="margin-bottom:16px">While some critics fear a sharing-first approach will dampen incentives and scare off industry, SGC’s open science policy, which expressly forbids patenting on its research, has so far had precisely the opposite effect. Over the past 15 years, the expansion of SGC’s open science remit has only served to bring more industry partners to the table.</p> <p style="margin-bottom:16px">A more recent SGC project – Critical Assessment of Computational Hit-Finding Experiments (CACHE) – was organized with several partners from Big Pharma and aims to accelerate development of AI methods in drug discovery. It invites experts to participate in “challenges” around predicting which small molecules bind to specific target proteins implicated in diseases including Parkinson’s disease and COVID-19, and placing the drug starting points in the public domain. <a href="https://cache-challenge.org/cache-bridging-gap-between-molecule-discovery-and-computational-design">In an interview for the CACHE website</a>, Alexander Hillisch, vice-president and head of computational molecular design at Bayer AG in Wüppertal, Germany – one of the companies supporting CACHE – said the incentive for companies lies in being able to access quality experimental data and get to know the most skilled scientists for potential future collaborations. &nbsp;</p> <p style="margin-bottom:16px">Beyond his stewardship of SGC, Aled has founded and led numerous companies including the more traditional Affinium Pharmaceuticals, a venture-backed company that developed and sold a new antibiotic, and <a href="/news/making-medicine-not-money-how-one-u-t-researcher-s-startup-rethinking-big-pharma-s-business">the more unusual M4K Pharma</a>, which is developing new, but affordable, therapeutics for rare children’s cancers using an open science business model.</p> <p style="margin-bottom:16px">Aled sums it up: “To me, in my work, open science is not an end – it’s a business tactic to reach an end, which is to help us understand more about the human genome and human biology, and to allow this knowledge to be translated as rapidly as possible to drive new treatments.”</p> <p style="margin-bottom:16px">Elizabeth, meanwhile, traces her early forays into open science to when she worked with industry partners to develop a microbial culture, KB-1, <a href="/news/invisible-clean-crew-engineering-microbial-cultures-destroy-pollutants">that can dechlorinate pollutants in groundwater</a>. That invention led to the creation of the spinoff company SiREM.</p> <p style="margin-bottom:16px">Since KB-1 was a collaborative discovery, patenting it became more of a headache than it was worth.</p> <p style="margin-bottom:16px">“When we started working together, we weren’t thinking about IP – it wasn’t even on the radar,” says Elizabeth, a <a href="https://www.provost.utoronto.ca/awards-funding/university-professors/">University Professor</a> in the department of chemical engineering and applied chemistry in the Faculty of Applied Sciences &amp; Engineering who is cross-appointed to the department of cell and systems biology in the Faculty of Arts &amp; Science.</p> <p style="margin-bottom:16px">“So, we just negotiated a royalty and have kept working together ever since, with students going back and forth.”</p> <p style="margin-bottom:16px">KB-1 has since been deployed at some 900 sites around the world by organizations ranging from Fortune 500 companies to NASA, with SiREM continuing to collaborate with Elizabeth and her students to develop cultures that can degrade other contaminants.</p> <p style="margin-bottom:16px"><img alt src="/sites/default/files/UofT84648_0204BioZoneTour020087A3900-lpr.jpg" style="width: 750px; height: 500px;"></p> <p style="margin-bottom:16px"><em>Elizabeth Edwards gives a tour of 鶹Ƶ’s BioZone research centre, which has freely disseminated nearly all of its research&nbsp;(photo by Nick Iwanyshyn)</em></p> <p style="margin-bottom:16px">Elizabeth is also the founding director of <a href="https://www.biozone.utoronto.ca/">BioZone, an interdisciplinary research centre</a> that is dedicated to developing biotechnologies that address sustainability challenges. Nearly all of of BioZone’s past research output has been disseminated freely, and all new industry partnerships are being pursued using the no-patent, open science approach – including <a href="http://www.biomining.ca/about-project/">Elements of Bio-Mining</a>, which aims to harness microbial science to stabilize waste tailings from mining. Industry partners include mining giant Vale and commodity trader Glencore.</p> <p style="margin-bottom:16px">The 鶹Ƶ open science industry partnership roadmap is also driving similar projects across Canada. That <a href="https://www.openplastic.com/">includes “Open Plastic,”</a> led by Queen’s University assistant professor<b> </b>and 鶹Ƶ alumnus <b>Laurence Yang</b>, which focuses on the discovery of enzymes that can break down plastics in the environment – and has attracted partners including chemicals giant DuPont; Star Produce, a distributor of fruits and vegetables; and Carbios, the first industrial-scale foray into enzymatic PET recycling.</p> <p style="margin-bottom:16px">Elizabeth says the long list of corporate partners that have collaborated on open science ventures proves that IP isn’t the main motivating factor for companies looking to work with universities. With the help of student interns from the Faculty of Law, Elizabeth, Aled and colleagues at BioZone rebutted common misconceptions about industry partnerships in an article titled <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/cjce.24077">“Could open science stimulate industry partnerships in chemical engineering university research?”</a> published in the <i>Canadian Journal of Chemical Engineering</i>.</p> <p style="margin-bottom:16px">“The people who work in companies read the same literature as professors do, and they’re just as smart and capable – but they have a different mandate,” she says.</p> <p style="margin-bottom:16px">“If something interesting happens in their labs but it’s a little bit sideways, they’re not allowed to pursue it because they have a core business to stick to. So, these companies love [open science partnerships] because it helps them find out more about the things they wish they could do, but don’t have time for.”</p> <p style="margin-bottom:16px">Aled agrees.</p> <p style="margin-bottom:16px">“Industry loves the clarity of the policy; they know exactly what they’re going into the collaboration for – to talk science, to engage with brilliant young people, to do science they would not have the time to do internally, and to get excited about the latest scientific developments,” he says.</p> <p style="margin-bottom:16px">“Elizabeth and I see the university’s role in the innovation economy as being a vehicle for industry to ask far-out questions, while allowing them a way to engage and attract students to their problems – and students really enjoy tackling real-world problems.”</p> <p style="margin-bottom:16px">He adds that 鶹Ƶ’s support of his and Elizabeth’s&nbsp;open science initiatives has placed the university in a leadership position in industry engagement worldwide.</p> <p style="margin-bottom:16px">“In supporting us to explore this radical way to innovate, 鶹Ƶ has painted a picture of how the Canadian university of the future can work with the private sector and others to tackle big problems and more effectively move ideas from the lab to the market.</p> <p style="margin-bottom:16px">“It’s an innovation on innovation, and we hope 鶹Ƶ continues to lead the way.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 07 Nov 2022 15:38:12 +0000 rahul.kalvapalle 177490 at Good for you, better for the planet: 鶹Ƶ cyclists pedal toward a more sustainable future /news/good-you-better-planet-u-t-cyclists-pedal-toward-more-sustainable-future <span class="field field--name-title field--type-string field--label-hidden">Good for you, better for the planet: 鶹Ƶ cyclists pedal toward a more sustainable future </span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Beth-Austerberry-and-Walid-Maraqa-crop.jpg?h=afdc3185&amp;itok=NA9ZTkfe 370w, /sites/default/files/styles/news_banner_740/public/Beth-Austerberry-and-Walid-Maraqa-crop.jpg?h=afdc3185&amp;itok=UUBl9Lme 740w, /sites/default/files/styles/news_banner_1110/public/Beth-Austerberry-and-Walid-Maraqa-crop.jpg?h=afdc3185&amp;itok=n1a_Agj1 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Beth-Austerberry-and-Walid-Maraqa-crop.jpg?h=afdc3185&amp;itok=NA9ZTkfe" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2022-10-20T16:13:42-04:00" title="Thursday, October 20, 2022 - 16:13" class="datetime">Thu, 10/20/2022 - 16:13</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Beth Austerberry, executive director of Bikechain, helps Walid Maraqa, a grad student in biostatistics, perform basic maintenance on his bike (photo by Geoffrey Vendeville)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/mariam-matti" hreflang="en">Mariam Matti</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/city-culture" hreflang="en">City &amp;

"And it seems that based on our data, this happened before toothed and baleen whales diverged. The common ancestor of all living cetaceans was deeper diving – and then later species evolved all the diverse foraging specializations we see in modern whales and dolphins today."</p> <p>Chang worked with <strong>Sarah Dungan</strong>, a former member of Chang's lab who has a PhD in ecology and evolutionary biology from 鶹Ƶ, on a study describing their experiments, computational analysis and results in the&nbsp;<a href="https://www.pnas.org/doi/full/10.1073/pnas.2118145119"><em>Proceedings of the National Academy of Sciences</em>.</a></p> <p>Deep diving by marine mammals is one of the great evolutionary transitions, along with powered flight and living on land, and reveals much about how quickly life can adapt in a changing world.</p> <p>Whales evolved from mammals that share a common ancestor with hippos and that were partially aquatic. The great mystery of their transition to deep-sea foraging was how quickly this ability developed. Dungan and Chang looked at whale fossils on a molecular level and focused on the rhodopsin protein, which absorbs light and sends a signal that travels through the retina to the brain.</p> <p>“One of the most intriguing aspects of this iconic land-to-sea evolutionary transition is that the qualities of the visual environment completely changed,” says Chang. “This helped to define which genes would be the most interesting for us to target in our studies.”</p> <p>Dungan applied robust data science models to rhodopsin proteins from a variety of living whales and related mammals. This computerized analysis revealed a gene sequence representing the rhodopsin found in the common ancestor of all living whales. She expressed this gene in lab-grown cells to “resurrect”&nbsp;the predicted protein and experiment on purified samples.</p> <p>"The fossil record is the gold standard for understanding evolutionary biology,” says Dungan. “But despite what Jurassic Park would have you believe, extracting DNA from fossil specimens is rare because the condition tends to be poor. So, if you’re interested in how genes and DNA are evolving, you rely on mathematical modelling and a strong sample of genes from living organisms to complement what we understand from the fossil record."</p> <p><img alt src="/sites/default/files/UofT14044_20160211_BelindaChang_3842-crop.jpg" style="width: 750px; height: 500px;"></p> <p><em>Belinda Chang (back left) leads a lab that focuses on the evolutionary transition of animals' vision.&nbsp;Sarah Dungan (right of Chang) researched whale vision as a former member of Chang’s lab (photo by Diana Tyszko)</em></p> <p>Dungan and Chang were astonished by the biochemical properties of the resurrected protein compared to land mammals. Early whale rhodopsin was more sensitive to the blue light that penetrates deepest into the ocean, to a degree that exceeded expectations. Its biochemical properties also suggested that the retinas of early whales could respond rapidly to changes in light levels.</p> <p>Early whales eventually evolved into the many kinds of toothed whales and baleen whales we see today. As separate species of whale evolved, they established ecological niches at various levels of the sea and even in freshwater rivers. Dungan and Chang’s work shows that there were further evolutionary adaptations as members of both groups either surfaced from the early deep levels to hunt closer to the surface or specialized to become even more extreme divers.</p> <p>"I’ve always been fascinated by whales,” says Dungan. “The idea that there was a land mammal like me that eventually evolved to live underwater blew my mind as a kid, even though I really didn't understand exactly what that meant at the time.</p> <p>“It is amazing that now&nbsp;we can have this level of insight into the lifestyle of a long-extinct organism, just from doing laboratory experiments on one protein. Ancestral protein resurrection is an incredibly powerful way for us to interrogate how ancient organisms evolved that most people don't know about,” she adds.&nbsp;</p> <p>Next, Dungan and Chang plan to resurrect the ancestral whale proteins that transmit the rhodopsin light signal from the retina to the brain to provide insights into the neurological adaptations associated with deep diving. They will probe ancient evolutionary adaptations associated with new behaviours and hope to gain greater insight into how animals may adapt to a changing world.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 28 Jul 2022 15:37:02 +0000 Christopher.Sorensen 175816 at
