The Wnt and Notch signalling pathways represent two of the core pathways critical to the determination of cell fates during the development of all metazoa. Many conserved components and mechanisms of these pathways have been described through work carried out using the Drosophila wing model. The precise patterning of the wing margin is achieved...

Members of the Hedgehog family of morphogens mediate the intercellular communication necessary for the organisation and development of many animal tissues. They are modified by various lipid adducts, rendering them insoluble in hydrophilic environments and leading to the contentious question of how these molecules travel in the aqueous...

ABSTRACT Wnt signalling is a core pathway involved in a wide range of developmental processes throughout the metazoa. In vitro studies have suggested that the small GTP binding protein Arf6 regulates upstream steps of Wnt transduction, by promoting the phosphorylation of the Wnt co-receptor, LRP6, and the release of β-catenin from the adherens...
