\"Troph\u00e9es
Troph\u00e9es du International Genetically Engineered Machine | \u00a9 iGEM<\/figcaption><\/figure>\n

Des \u00e9tudiants de l\u2019Universit\u00e9 technique de Riga<\/a> et de l\u2019Universit\u00e9 de Lettonie<\/a> ont remport\u00e9 l\u2019une des 191  m\u00e9dailles d\u2019or \u00e0 l\u201d\u202f\u202f\u00bbInternational Genetically Engineered Machine\u202f\u00bb (iGEM)<\/em><\/a>, <\/em>le plus grand concours d\u2019innovation en biotechnologie au monde qui s\u2019est d\u00e9roul\u00e9 \u00e0 Paris en novembre, apr\u00e8s avoir d\u00e9velopp\u00e9 une enzyme d\u00e9riv\u00e9e des plantes<\/a> capable de promouvoir le d\u00e9veloppement de nouveaux m\u00e9dicaments et pesticides.<\/p>\n

La biotechnologie est un domaine qui recouvre l\u2019ensemble des technologies et applications ayant recours \u00e0 l\u2019utilisation ou \u00e0 la modification de mat\u00e9riaux vivants dans un objectif de recherche scientifique pour accro\u00eetre les connaissances humaines.<\/p>\n

\u00ab\u202fNous avons d\u00e9couvert une enzyme pr\u00e9sente dans plusieurs plantes et capable de former des peptides cycliques. De nombreux peptides cycliques issus de la nature sont r\u00e9guli\u00e8rement synth\u00e9tis\u00e9s en laboratoire mais la diff\u00e9rence est que, cette sp\u00e9cifique enzyme pourra \u00eatre utilis\u00e9e pour cr\u00e9er des mol\u00e9cules complexes que les chimistes ne pouvaient jusqu\u2019\u00e0 pr\u00e9sent pas synth\u00e9tiser\u202f\u00bb,<\/em> a d\u00e9clar\u00e9 M. Drunka au m\u00e9dia letton LSM.<\/a><\/p>\n

L\u2019enzyme en question est d\u00e9riv\u00e9e de l\u2019arachide. Les \u00e9tudiants ont eu l\u2019occasion de d\u00e9montrer qu\u2019une telle enzyme peut \u00eatre pr\u00e9lev\u00e9e et utilis\u00e9e en laboratoire.<\/p>\n

Les doctorants pensent qu\u2019\u00e0 l\u2019avenir, cette substance pourrait \u00eatre utilis\u00e9e dans l\u2019agriculture<\/a> pour cr\u00e9er des herbicides respectueux de l\u2019environnement. Elle aurait \u00e9galement le potentiel de cr\u00e9er de nouveaux m\u00e9dicaments.<\/p>\n

\u00ab\u202fLes peptides cycliques ont diverses propri\u00e9t\u00e9s anti-inflammatoires et analg\u00e9siques qui peuvent \u00eatre utiles dans le domaine m\u00e9dical<\/em>\u202f\u00bb, a ajout\u00e9 M. Drunka.<\/p>\n

Pour promouvoir la biologie synth\u00e9tique et les possibilit\u00e9s qu\u2019elle offre, les \u00e9tudiants ont \u00e9galement cr\u00e9\u00e9 un jeu pour les \u00e9coliers dans le cadre du concours. \u00ab\u202fNous avons test\u00e9 le jeu dans plusieurs classes avec des enseignants. Nous esp\u00e9rons inclure le jeu dans le mat\u00e9riel p\u00e9dagogique des \u00e9coles afin que les \u00e9l\u00e8ves en apprennent davantage sur la biologie synth\u00e9tique et ses applications<\/em>\u202f\u00bb, a d\u00e9clar\u00e9 Alice Anna Stipniece-Jekimova, assistante de recherche \u00e0 l\u2019UTR.<\/p>\n

Les \u00e9tudiants pr\u00e9voient de poursuivre leurs recherches sur la biologie synth\u00e9tique avec des enzymes et souhaitent voir leurs d\u00e9couvertes utilis\u00e9es dans l\u2019agriculture et la production de m\u00e9dicaments.<\/p>\n

Des doctorants de l\u2019Universit\u00e9 d\u2019\u00c9vry Paris-Saclay et un groupe de l\u2019Universit\u00e9 Claude Bernard, de l\u2019INSA et de l\u2019\u00c9cole Normale Sup\u00e9rieure de Lyon ont \u00e9galement remport\u00e9 des m\u00e9dailles d\u2019or.<\/p>\n
