Summary
Cell migration is an essential feature of physiological processes involved in embryo development, as well as disease conditions such as cancer metastasis. Cell movement requires extensive changes to the cell surface. We have identified a vital pathway involved in membrane trafficking during cell migration. This proposal aims to identify the cellular components involved in this pathway, screen for new inhibitors, and characterise the role of this pathway in migrating cancer cells.

Summary
Muscle fibres contain an elaborate system of membranes that allow the fibre to contract. This proposal aims to understand how this membrane system develops and how this process is disrupted in disease.
Many bacterial pathogens invade host cells to replicate and avoid detection by the host. These pathogens interact with the host and by manipulating it to its benefit they establish an environment to survive in. A detailed understanding of the targeted hosts pathways and which are essential for pathogen survival is knowledge that will allow future development of therapeutic intervention strategies.
Membrane Trafficking Of The ?-secretase, BACE1, And The Generation Of Alzheimer's Disease A? Amyloid Peptides

Summary
Alzheimer’s disease results from the production of toxic neuropeptides by the action of an enzyme called BACE. The generation of toxic peptides requires the movement or trafficking of BACE between different cell compartments. This research will reveal the molecular machinery of the BACE transport pathway. This new knowledge will provide a strategy to develop drugs to inhibit BACE activity and the production of the toxic peptide, which would be of significant benefit to patients and families.
Regulated Intracellular Trafficking Of A Potassium Channel In Gastric Acid-secreting Cells

Summary
The cells of our bodies possess proteins that transport salts and other chemicals. These transport proteins must be correctly positioned in cells, a process that is poorly understood. If transport proteins are not positioned properly then diseases such as heart attack or diabetes may occur. Influencing the position of transport proteins may also be used to treat disease. This work investigates how a transport protein that shuttles potassium is correctly positioned in cells of the stomach.
MOLECULAR CELL BIOLOGICAL ANALYSIS OF CAVEOLIN SECRETION

Summary
Aggressive forms of prostate cancer are associated with the release of a protein, called caveolin, from the cancerous cells. Caveolin is normally embedded in the cell surface and drives the formation of microscopic pits termed caveolae. In this proposal we will investigate how caveolin is secreted with a long-term goal of preventing the secretion, or the action, of caveolin.
