Summary
Radiotherapy (RT) is responsible for 40% of cancer cures. New technology enables RT delivery in fewer treatments using higher radiation dosages through a technique called 'ART'. While ART is effective in the clinic, the underlying mechanisms of cancer cell death are unclear. Here we show that ART induces two distinct waves of cancer cell death. We will characterize these waves of cell death and determine how to enhance tumour cell killing with pharmacological intervention.
ASIC1a, A New Therapeutic Drug Target For Cardiac Ischemia

Summary
Cardiovascular disease is the biggest killer in the world, in large part due to the lack of drugs to protect the heart from the damage caused by injuries such as heart attack. Our team of world-leading scientists and clinicians has identified a novel therapeutic target (ASIC1a) against which drugs could be targeted to protect the heart against these injuries. The aim of this project is to develop novel cardioprotective drugs that target ASIC1a so we can test them in human clinical trials.
Understanding The Role Of Lipid In Membrane Permeabilization By The Bcl-2 Family Executioner Proteins

Summary
Apoptosis is a form of programmed cell death that protects our bodies from dangerous cells, e.g cells infected with viruses or that might become cancerous. A network of protein families control this process and this work will understand how certain members regulate a crucial step in this cell death pathway. Our studies will reveal key insights into apoptosis at the molecular level and inform the development of therapeutics for diseases characterised by dysregulated cell death such as cancer.
Deadly Commute - Targeting The Trafficking Mechanisms That Licence Inflammatory Cell Death

Summary
MLKL is a protein naturally found inside cells. MLKL is activated by inflammation. Once activated, MLKL relocates to the outer periphery of cells and kills them. Gut cells are especially vulnerable to death-by-MLKL and this problem causes Inflammatory Bowel Disease. Using cutting edge microscopy, we have discovered how MLKL moves to the periphery of cells prior to killing them. We will test if blocking this movement of MLKL to the cell periphery stops gut death and Inflammatory Bowel Disease.
Sudden cardiac death (SCD) is a devastating consequence of a number of heart diseases. Underlying causes include inherited heart muscle problems (cardiomyopathies), with no cause found in 40%. Our study will investigate the role of 'concealed cardiomyopathy' cases, i.e. those with a SCD event with no evidence of heart disease, but carry errors in heart genes. Our findings will translate rapidly into more targeted clinical and genetic evaluation of families with the ultimate goal to prevent SCD.
Investigating The Consequences Of Dysregulated Lipogenesis In Cancer

Summary
Reprogramming of cellular metabolism is a hallmark of cancer. As such, there has been growing interest in developing strategies to exploit metabolism for therapeutic gain. Our ability to do this is dependent on a thorough understanding of the mechanisms by which dysregulation of cellular metabolism contributes to tumour progression. In this project, we seek to the investigate the fundamental mechanisms by which aberrant activation of lipid metabolism contributes to the tumourigenic process.
Reprogramming Human Fibroblasts Into Induced Trophoblast Stem Cells

Summary
We have been able to generate artificial human trophectoderm which is the tissue that creates the placenta. This will allow us to do research in how the genes control the fate of these cells without the need of human embryos or placenta. We anticipate that the derivation and characterising these cells will revolutionise placenta research, which in turn will contribute to the establishment of new therapies for placenta disease and infertility.
Advancing The Spatial Analysis Of Cells In Tissues To Profile The Tumour Microenvironment

Summary
Tumours are composed of a mix of different cells, including cancer cells, immune cells and other cells supporting tumour growth. These cells are not organised randomly, but rather are distributed in specific patterns. Here we will develop computational methods to detect these patterns and determine what statistical tests should be used to compare samples. This project will give us the tools to investigate how the location of cells in tissues relates to treatment response and survival.
Stopping Breast Cancer Progression By Targeting Tumour Stroma

Summary
Our latest research demonstrated that CRELD2 protein that is secreted by breast cancer cells alters normal cells surrounding tumour. CRELD2 represents an ideal therapeutic target as it is not important for normal cells and it is a secreted protein and thus can be targeted by numerous means. Successful completion of this research proposal will provide foundation to find new targets for combining therapies affecting both tumour and it's altered environment in breast and potentially other cancers.
Dendritic Cells Govern The Balance Between Immunity And Homeostasis To Inhaled Antigen

Summary
The development of better intranasal vaccines hinges on the improved understanding of how the immune response is initiated following vaccine delivery into the upper airways. In this project we will provide fundamental understanding of how immune responses to inhaled antigens are regulated; this considerable conceptual advance will lay the foundation for which new intranasally delivered immunotherapies will ultimately emerge.
