Project description:

Defects in nerve cell development are linked to various brain disorders. Radial glial cells (RGCs) in the brain play a key role in neurogenesis and oestrogens are believed to play important modulatory roles in neurogenesis and cognition. This project will apply novel genetically-engineered zebrafish models to investigate oestrogen signaling in neurogenesis and brain development. Zebrafish are particularly suited to this work, as they show substantial neurogenic activity throughout life.

We have developed transgenic zebrafish that allow us to dynamically image oestrogen-responsive cells in living animals in real time. The fish glow red at sites responding to oestrogen via the oestrogen receptor. Very recently, with collaborators in France, we advanced this model allowing us to identify sub-populations of neuronal progenitor cells that are responsive to both oestrogen (glowing red) and those responding to  an enzyme that is involved with oestrogen synthesis (aromatase, glowing green), simultaneously. In this exciting and cutting edge project, the successful student will investigate the functional roles of oestrogens in neuronal development and will identify the different classes of neural cells responsive to oestrogens and how they develop. The student will furthermore develop a further, more complex (triple), transgenic zebrafish expressing also a genetically-encoded fluorescent calcium probe to report nerve activity. Using this model, the student will investigate the roles of oestrogen-responding neurons in the sense of smell. Time allowing, the student will also initiate studies into effects of exposure to endocrine-disrupting chemicals, for which there is widespread health concern, on oestrogen-responsive cells and their subsequent fate and function.

This is a truly novel and exciting project and student will get an outstanding training in a wide range of core bioscientific methodologies spanning molecular methods to histopathology, as well as significant experience of various cutting edge imaging techniques (light, 2-photon fluorescence and Coherent anti-Stokes Raman Scattering) and in both cellular neurophysiology and in-life exposures. The student will join large and vibrant research teams with considerable experience, expertise and infrastructure providing superb support for the PhD training.
