TITLE: Formal methods from computer science to treat temporal properties of biological regulatory networks, applied to cytotoxicity in Pseudomonas aeruginosa. AUTHORS: Gilles BERNOT, Jean-Paul COMET, Janine GUESPIN ABSTRACT: Based on the discrete definition of biological regulatory networks developped by René Thomas, we provide a computer science formal approach to treat temporal properties of biological regulatory networks, expressed in Computational Tree Logic. It is then possible to build all the models satisfying a set of given temporal properties. Our approach is illustrated with the cytotoxicity in Pseudomonas aeruginosa. This application of formal methods from computer science to biological regulatory networks should open the way to many other fruitful applications. KEYWORDS: biological regulatory networks, formal methods, temporal logic, model checking.
