Project Description

Although 90% of cancer deaths are caused by metastasis, the underlying pathogenic mechanisms are poorly understood. Cell plasticity is the ability of cells to reversibly change their phenotype and plays a critical role at multiple steps in the complex process of tumour dissemination, which relies on cells undergoing an epithelial-to-mesenchymal transition (EMT), migrating away from the primary tumour and later undergoing a reverse mesenchymal-to-epithelial transition (MET). While several transcription factors that regulate EMTs have been isolated, how these actually impinge on the cellular responses underlying cell plasticity remains poorly understood. Even less is known about MET: we have so far failed to identify the signals required for its induction, nor do we understand how it occurs at the cell and molecular level.

We are looking for a PhD student to work on a project targeted towards identifying the molecular mechanisms underlying epithelial cell plasticity during development and disease. The project will involve studying how this fundamental property is orchestrated during morphogenesis of the Drosophila midgut, and also in exciting Drosophila cancer models that we have recently generated. This project will combine molecular biology with powerful Drosophila genetics, quantitative image analysis and high-resolution microscopy on our own dedicated multiphoton confocal. It will also involve making targeted Drosophila mutants using CRISPR, and analysing their effects at the subcellular level in fixed and living samples. This is a unique opportunity for you to carry out cutting-edge microscopy, and develop your skills in an exciting multidisciplinary environment.
