A product of Vitamin A metabolism, retinoic acid, has long been known to aid the development of nerve cells, which are cells that process and transmit information in the brain through electrical and chemical signals. <\/span><\/p>\n Brock University biologist Gaynor Spencer is examining how retinoic acid guides the growing nerve cells during their development and regeneration.<\/p>\n Specifically, she\u2019ll be looking at how the growing tips of these nerve cells, called \u201cgrowth cones,\u201d turn towards retinoic acid and investigate how retinoic acid changes the direction of growth. She will be using snails to study this process.<\/p>\n \u201cIf we can utilize the snail nerve cells to actually determine how retinoic acid is doing this, then hopefully that information will be applicable to understanding growth-cone behaviour in vertebrates and mammals,\u201d says Spencer.<\/p>\n She is also examining the role that retinoic acid has in the adult brain by studying how it might be important for learning and memory.<\/p>\n \u201cWhat we\u2019ve shown in the snail is that when we block the retinoic acid signaling pathway, the animals will still learn, but they won\u2019t show long-term memory,\u201d says Spencer. Her next research phase will be to record the exact changes that take place in the cells of the snail\u2019s brain that might determine why the snail can\u2019t form memory in the absence of retinoid signaling.<\/p>\n But Spencer cautions that it\u2019s still very early days to make the leap to human beings in terms of retinoic acid use for boosting memory. She said the snail is \u201ca relatively simple model system to try to understand basic mechanisms of how these molecules are important in memory processes.\u201d<\/p>\n Spencer is one of 15 Brock University researchers who received Discovery Grant awards totaling $1.98 million for the 2015-2020 funding period. The federal granting agency Natural Sciences and Engineering Research Council (NSERC) announced the results of the 2015 Discovery Grants, scholarships and fellowships competitions for universities across the country June 22.<\/p>\n \u201cOur success rate for those already holding a grant is an impressive 83 per cent, <\/span>which was well above the average (65 per cent) for small universities in this year’s competition<\/span>,\u201d says Joffre Mercier, associate vice-president research of Natural and Health Sciences.<\/span><\/p>\n \u201cThis reflects the hard work and leading-edge quality of our researchers\u2019 work and our growing reputation as a research-intensive university,\u201d he said, adding that Brock received a one-year Research Tools and (RTI) grant of over $25,000.<\/p>\n In addition, seven Brock graduate students were recognized for research excellence with scholarships and fellowships totaling $318,500.<\/p>\n \u201cIn a very competitive funding environment, it is a tremendous accomplishment for our graduate students to be selected to receive NSERC awards,\u201d says Mike Plyley, Dean, Faculty of Graduate Studies. \u201cThe awards are a clear measure of excellence and recognition of the\u00a0scope and calibre of work that our students pursue and the potential that their work holds in contributing to discovery and innovation in Canada.\u201d<\/p>\n Research programs for the 14 Discovery Grant recipients span a broad array of subjects ranging from developing prospective memory in young children<\/a> <\/span>to <\/span>biological reasons for why people perceive flavour differently to expanding knowledge of how Vitamin E interacts with cell membranes<\/a>.<\/span><\/p>\n For her part, Spencer says the $225,000 grant she received over five years will allow her to continue to do \u201ccompetitive\u201d research and to train high-quality graduate students. \u201cNSERC is a lifeline; I wouldn\u2019t be able to continue running a research lab at this level without the NSERC funding.\u201d<\/p>\n NSERC\u2019s \u201cflagship\u201d Discovery Grants program provides core research funding\u00a0 \u201cso Canada\u2019s best researchers can pursue their most promising ideas and breakthrough discoveries \u2013 world firsts in knowledge,\u201d said the agency\u2019s June 22 media release.<\/p>\n \u201cToday\u2019s investment in more than 3, 800 researchers at 70 universities across the country ensures Canada has a broad base of talented men and women whose research continues to push the boundaries of knowledge, creates jobs and opportunities while improving the quality of life of Canadians,\u201d said <\/span>Ed Holder, Minister of State (Science and Technology).<\/span><\/p>\n Brock
