The present invention relates to the field of Hedgehog signalling, and more specifically to a cell-based assay system and methods for identifying inhibitors and/or antagonists of specific cellular events in said signalling pathway. The present invention hereby proposes a novel approach for identifying inhibitors and/or antagonists downstream of the signalling components Smoothened and Patched, e.g. at the Gli-level. The assay comprises cells lacking a functional Sufu protein, which according to the invention is a protein component of emerging importance in the Hedgehog signalling pathway.

[FR] La présente invention concerne le domaine de la signalisation Hedgehog, et plus particulièrement un système et des méthodes de dosage à base de cellules destinés à identifier des inhibiteurs et/ou des antogonistes d'événements cellulaires spécifiques dans la voie de signalisation. Cette invention porte sur une nouvelle approche visant à identifier des inhibiteurs et/ou des antagonistes en aval des composants de signalisation Smoothened et Patched, soit au niveau Gli. L'analyse porte sur des cellules auxquelles manque une protéine Sufu fonctionnelle laquelle, selon l'invention, est un composant protéique présentant une importance nouvelle dans la voie de signalisation Hedgehog.
