Description du projet
Prédire les résultats de la biologie synthétique
Les progrès technologiques accomplis ces dernières années ont permis aux scientifiques de construire des réseaux génétiques dans des organismes modèles grâce à la synthèse et à la modification de l’ADN. Cela dit, l’introduction de composants régulateurs dans ces circuits génétiques s’est révélée délicate en raison du risque de perturber la fonction de la cellule hôte par des interférences avec d’autres composants. Financé par le Conseil européen de la recherche, le projet PLATE part du principe que les modèles actuels ne sont pas suffisamment précis pour prédire de manière fiable le fonctionnement des unités de régulation dans des contextes spécifiques à l’intérieur des cellules. L’équipe propose d’intégrer les méthodes de calcul disponibles dans une plateforme cohérente et conviviale destinée aux chercheurs travaillant dans le domaine de la biologie synthétique.
Objectif
Advances in our capabilities to program, synthesize and modify DNA has led to a surge in the field of synthetic biology. Various gene circuits have been proposed and designed in various organisms for application domains ranging from biomedicine over biotechnology to biomaterials. Our current bottleneck is not anymore our ability to program and synthesize custom DNA, but rather our ability to design regulatory circuit that realize the desired functionality and operate reliably in a specific target host cell or in vitro systems. The largest hurdle that we identify is the context-dependency of synthetic circuits, i.e. their perturbation by other molecular factors belonging to the host cell. Given the complexity of these molecular systems, current design approaches that rely on trial-and-error will not be able to produce meaningful designs in a reliable, fast and systematic manner at the scale required for industrial applications. Although genetic design automation tools are available to overcome this unsatisfactory state of affairs their practical impact have been limited. This is due to the fact that the used models are not accurate enough, in particular, they cannot predict reliably the performance of a circuit design when operating within a host cell. The main reason for this limited predictive power is that models do not take into account the named context-dependency of circuits.
The current project PLATE takes on this challenge and leverages methods developed within the ERC Project CONSYN that allow for accurate modeling of context-effects through the use of detailed biophysical models. The aim of PLATE is to integrate all those computational methods into a coherent design environment for the synthetic biology researcher in academia and in industry. The resulting PLATE software suite follows a modular approach where different analysis types and different design methods can be selected according to the specific need of a given academic or industrial project.
