Summary
The ‘triple negative’ breast cancer subtype is the most aggressive form of breast cancer, and unlike other subtypes, there are no drugs to specifically this subtype. While many potential drug targets have been identified, they cannot be utilised clinically because of other beneficial roles within the body. We are now deploying our innovative experimental platforms to specifically target the tumour promoting functions of a protein known as ‘JNK’, whilst retaining its beneficial functions.
How Do Mutations In Autophagy Receptors Cause FTD And ALS?

Summary
As cells age the "garbage disposal" process within cells slows down, becoming less functional. In inherited forms of dementia the genes involved often code for damaged proteins that "clog up" the disposal system or directly affect the “garbage men”. These defective garbage men genes include SQSTM1/p62, OPTN, VCP and UBQLN2. We will determine how these defective genes lead to build up of garbage in neuronal cells and how leads to disease.
Diabolic Regulation Of Macrophage Cell Death Pathways By Legionella

Summary
The bacterial pathogen Legionella causes fatal pneumonia in immuno-compromised humans. Infections depend on a sophisticated secretion machinery that translocates hundreds of proteins into host cells. These proteins subvert several essential defense pathways, including cell death signals. This project will highlight how Legionella interfere with cell death pathways and control the survival of its host cells. These findings will facilitate the development of promising new anti-bacterial agents.

Summary
Sphingosine kinase is a protein involved in the development and progression of numerous types of solid tumors and leukaemias. We have recently made a major break-through by identifing how the cancer-inducing activity of sphingosine kinase is controlled. In this study we will target these control mechanisms to develop potential new anti-cancer therapies.
New Mediators Of GPCR-growth Factor Receptor Transactivation

Summary
Hormones bind to receptors on the surface of cells. Receptors can modify each other’s function and this “cross-talk” is important for the receptors for a peptide hormone (termed angiotensin) and a growth factor receptor (EGFR), which are major regulators of the cardiovascular system. We have identified a number of mediators of the angiotensin-EGFR crosstalk and this current grant aims to use molecular and cellular and in vivo approaches to examine the molecular basis of their actions.
Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Dissecting The Role Of Selective Insulin Resistance In Type 2 Diabetes

Summary
Insulin resistance is a clinical condition where insulin, secreted from the pancreas in response to meals, is unable to fulfill its normal function. It is intimately linked to obesity and associated diseases - type 2 diabetes, cancer and cardiovascular disease. This proposal examines mechanisms contributing to insulin resistance and how insulin resistance leads to disease. We will identify drug targets with improved specificity and lead to novel insight into the risks of current treatments.
The Characterization Of A Novel Pseudokinase Regulator Of Platelet Formation

Summary
Mammalian cells contain a complex switchboard, which directs the cell to grow, die, multiply or move in response to external cues. When communication breaks down within the cell, diseases arise. Our studies are directed towards identifying the molecules that comprise the switchboard which directs blood cell formation. A detailed understanding of the regulators of blood cell formation will equip us with a sound starting point for designing drugs to ameliorate blood diseases.
Dynamic regulation of cell signalling scaffolds. This project aims to determine how cells utilise scaffold-type signalling proteins to orchestrate, over time, diverse cellular responses critical for normal development and physiology. The project expects to generate fundamental new knowledge in cell and synthetic biology with broad relevance that will foster establishment of new international linkages and networks.

To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innovative genome editing, mathematical modelling and proteomic approaches, to study how biochemical modifications of a key protein called tau help encode and retrieve memories. These molecular insights will make a significant advance in the current understanding of a brain function that is essential to all human activities.Read moreRead less
