Insulin triggers glucose uptake into fat and muscle tissue, a process that is defective in type 2 diabetes. Insulin does this by triggering a complex cascade of actions once it binds to muscle and fat cells. We will analyse the function of a crucial protein within this cascade. This protein is mutated in humans with severe insulin resistance and our proposed project will dissect how this protein works potentially providing a novel drug target to treat diabetes.
A Signalling Endosomal Network In T Cell Activation

Summary
T lymphocytes play a central role in the adaptive immune response, which specifically targets pathogens and cancer cells and creates the immunological memory. Activation of sometimes as little as one single receptor on a T cell triggers a cellular signal that rapidly expands and branches out in a multitude of sub-signals. Here we will use a combination of novel microscopy approaches to visualise how a network of dedicated intracellular compartments is in charge of these processes.
Characterising The Beta-catenin Nuclear Targeting Pathway In Cancer

Summary
Bowel cancer is caused by inherited gene mutations that cause build-up of beta-catenin protein in the cell nucleus. Bowel cancer is the second largest cause of cancer deaths in Australia. We aim to study the mechanisms controlling beta-catenin accumulation in the nucleus. We will characterise new signalling pathways that control movement and activity of beta-catenin in the nucleus. This will yield insights into the role of beta-catenin in cancer and possible targets for therapy.
