Roles for microtubule-associated proteins in cancer cells
The main research interests of the group are microtubule biology, with a particular interest in the role and regulation of microtubule plus-end binding proteins; Parkinson’s disease, with a focus on the role played by the protein Parkin in mitophagy and the potential role of immediate early gene functions in response to neuronal stress; and cancer, in close collaboration with colleagues in the Section.
Microtubules are dynamic biological polymers essential for eukaryotic life, playing indispensable roles in cell division and intracellular transport. Throughout my time in Leeds my research has been focused on the cell biology of microtubules (MTs) and microtubule-associated proteins (MAPs), a topic with wide applicability across medical research that has allowed me to pursue studies in areas as divergent as neurobiology and cancer research. At present, in collaboration with colleagues in Leeds, this research is examining the role played by a divergent member of the tubulin family in brain development, the potential roles of MAPs originally identified in studies of neurodevelopmental syndromes in cancer, and work on the biology of primary cilia, a MT-based organelle with a key role to play in cell signalling.
More recently, through a collaboration with Dr Phil Robinson (http://www.leeds.ac.uk/secretariat/obituaries/2012/robinson_philip_alan.html), I have developed an interest in the biology of Parkinson’s disease, particularly in relation to mitochondrial dynamics, the cellular response to mitochondrial dysfunction (mitophagy) and the potential role of signalling pathways linked to cell stress. I have also maintained a strong interest in cell imaging technologies while in Leeds; I played a major role in the development and use of confocal, live cell and high-content/high-throughput (HC/HT) imaging techniques in research in the School of Medicine. This has led to an interest in high-throughput screening strategies using both reverse genetics approaches and small molecule libraries, technology that is now being applied to my original research interests in the form of pilot HC/HT imaging screens aimed at defining factors involved in the regulation of MT growth.
