Projektbeschreibung
Vorhersage der Ergebnisse in der synthetischen Biologie
Die technologischen Fortschritte der letzten Jahre haben es den Wissenschaftlerinnen und Wissenschaftlern ermöglicht, durch die Synthese und Veränderung von DNS genetische Netzwerke in Modellorganismen aufzubauen. Die Einführung regulatorischer Komponenten in diese genetischen Schaltkreise hat sich jedoch als schwierig erwiesen, da dies die Funktion der Wirtszelle aufgrund von Interferenzen mit anderen Komponenten beeinträchtigen könnte. Das vom Europäischen Forschungsrat finanzierte Projekt PLATE geht von der Hypothese aus, dass die derzeitigen Modelle nicht genau genug sind, um zuverlässig vorherzusagen, wie sich regulatorische Einheiten in bestimmten Kontexten innerhalb von Zellen verhalten. Daher schlägt das Projektteam vor, verfügbare Berechnungsmethoden in eine kohärente und benutzungsfreundliche Plattform für Forschende zu integrieren, die im Bereich der synthetischen Biologie arbeiten.
Ziel
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.
