Summary
Blood clots cause heart attacks and most strokes, which are the most common cause of death in the world. Platelets are the cells in the blood that form these clots, and drugs that prevent platelet function are the major approach for heart attack and stroke prevention. However, many patients are resistant to the effects of existing therapies. These studies will develop a unique approach to prevent platelet function that may help overcome the limitations of current drugs.
Characterisation Of Autophagy Deficiency In Skeletal Muscle Homeostasis

Summary
Defects in skeletal muscle are a cause of muscle disease, and also have broad health implications for diabetes, obesity and liver disease. As such, it is important to understand the processes required for healthy muscle and how signals communicate from muscle to the liver and fat, which integrate whole body metabolism. This application examines how the cellular degradation process known as autophagy integrates these important processes by investigating a novel gene regulator of this pathway.
The immune system usually rapidly responds to eradicate infectious pathogens. However patients with mutations in the gene PI3KCD, which is important for delivering messages within immune cells, are unable to control infections with some bacteria and viruses. We will study the effects of these mutations on B cells, the immune cells produce antibodies that bind to and remove pathogens from our body. This will explain some of the clinical features of this disease and reveal potential new treatments
Investigation Of The Role Of PI3-kinase In The Regulation Of Angiogenesis

Summary
The formation of blood vessels is critical for the development of embryos, but also after birth in processes such as wound healing. However, the uncontrolled formation of new blood vessels is also a feature of many human diseases such as cancer, and eye diseases that lead to blindness in adults or in premature infants. We propose to identify new regulators of blood vessel development, in order to improve current treatment therapies for these debilitating diseases.
Molecular And Therapeutic Interactions In Colorectal Cancer

Summary
This project will use our unique preclinical models to unravel the molecular and cellular events underlying the cooperation between two important cancer-causing pathways, PI3K and Apc/Wnt, in driving the development of cancer in the gastrointestinal tract. Our studies will provide critical new insights into the clinical significance of this interaction as well as the potential role of these pathways in the prophylactic and therapeutic actions of aspirin in the context of colorectal cancer.
Breast cancer is the most common malignancy among females which affects 1 in 8 women. Normal cells only divide when they receive a stimulus however cancer cells divide uncontrollably and are able to spread to other sites in the body, a process known as metastasis. We have identified a cancer suppressing gene which regulates cancer spread. This grant aims to characterise the mechanisms by which this gene controls cell movement and breast cancer spread.
Characterisation Of PI3-kinase-dependent Signalling Networks In Breast Cancer

Summary
Breast cancer affects 1 in 8 women in Australia. Cancer cells are able to spread to other sites in the body by a process known as metastasis which is the leading cause of breast cancer death. We have identified a gene which controls breast cancer growth and metastasis. This grant aims to elucidate the mechanisms by which this gene co-operates with another gene to regulate breast cancer growth and metastasis which thereby may affect disease outcome.
Role Of INPP4B And Related Proteins In Human Cancer.

Funding Amount

Summary
Breast cancer is the most common malignancy among females, affecting 1 in 9 women. Cells normally divide only when they receive a stimulus. The PI3K pathway, which responds to these stimuli, has been implicated in cancer and when mutated induces cells to multiply uncontrollably and invade surrounding tissue. This grant aims to characterise the role of a cancer suppressing gene and a related family member play in the development of human breast cancer.
Trafficking Mechanisms Governing Receptor Availability For Signalling

Summary
Receptors on the cell surface allow cells to respond to their environment. We have recently discovered a new pathway for controlling the amount of receptors displayed on the cell surface, errors within which will lead to defects in development and diseases like cancer. We are studying how this new pathway controls the balance between how much receptors are destroyed after being activated and how much are recycled back for re-use.
The Effects Of Omega-3 Fatty Acids On Novel Anti-Inflammatory Metabolites And Telomere Length In Early And Later Life: Potential Implications For Long-Term Cardiovascular Risk

Summary
Exciting new effects of omega-3 fats from fish oil have recently been discovered which actively reduce inflammation and help prolong cell life. These mechanisms are relevant to the risk of complications of obesity and cardiovascular disease. We will study the effects of fish oil given in pregnancy, infancy and later in life, with a view to using omega-3 fatty acid supplements for both early prevention and later treatment of obesity and cardiovascular disease.
