Summary
Cell polarity is the property of cells to be spatially oriented in a tissue or organ. We have shown that Scribble, a key regulator of cell orientation, may keep tumour development in check. In this proposal, we will examine how disruption of Scribble promotes breast cancer using a combination of tissue culture studies and a newly established mouse model. Understanding how this new pathway can regulate breast tumour development may provide novel targets for therapeutic intervention in cancer.
Analysis Of Rho GTPase Signalling Pathways In An Epithelial To Mesenchymal Transition During Development Of The Mesoderm

Summary
A critical step in the progression of cancers that are derived from epithelial tissues is a transition from an epithelial cell type to a migratory mesenchymal cell type that can spread to other parts of the body. This change in cell behaviour also occurs, apparently by a similar mechanism, during the development of some normal tissue types. Here we propose to use an animal model of this process, coupled with advanced molecular genetic and cell biological techniques, to investigate a newly discov ....A critical step in the progression of cancers that are derived from epithelial tissues is a transition from an epithelial cell type to a migratory mesenchymal cell type that can spread to other parts of the body. This change in cell behaviour also occurs, apparently by a similar mechanism, during the development of some normal tissue types. Here we propose to use an animal model of this process, coupled with advanced molecular genetic and cell biological techniques, to investigate a newly discovered cell signalling mechanism required for the transition of cells from an epithelial form to a mesenchymal form. Understanding the molecular steps in this new pathway and discovering new genes involved will provide tools for understanding and preventing the metastasis of cancer cells.Read moreRead less
