Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which two proteins, Pix and Git, control tissue growth by regulating the Hippo pathway. These studies will be performed in flies. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.
How The Lateral Habenula Integrates Behavioral And Autonomic Functions: The VTA Dopamine Connection

Summary
When adverse events occur, the lateral habenula, an old brain nucleus, helps calculate the wisest corrective action by contributing to the “brake” that controls the brain’s dopamine reward system. Our research will show how the lateral habenula links corrective changes in behavior with coordinated changes in temperature. Understanding this link will greatly contribute to understanding the brain mechanisms that regulate our physiology during stressful situations and as part of mental illness.
The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammator ....The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammatory or allergic disease, such as arthritis or asthma. This team of researchers from the Hanson Institute in Adelaide, combining expertise in molecular and cell biology, protein chemestry, structual biology and animal models, has been working together for over 10 years, investigating the molecular mechanisms involved in controlling the formation and activities of blood vessels and white blood cells. This program seeks to further that understanding, and to develop drugs that have the potential of ameliorating the inflammatory condition.Read moreRead less

Summary
Nature is a source of incommensurable chemical diversity that throughout history have provided many useful bioactive compounds including anti-cancer drugs. Our recent results suggest that honeybees use royal jelly to regulate the expression of genes implicated in certain types of human cancer.The aim of this study is to identify inhibitors of cancer related genes in royal jelly and to understand the mechanism of their action. Our results could lead to novel combination therapies.

Summary
Excessive cough associated with an airways disease represents the most common reason for doctor consultations. However, the current therapeutic options for relieving excessive cough are limited. This proposal will provide unprecedented insights into the brain mechanisms that contribute to the development of cough disorders in airways disease.

Summary
Cell growth is a tightly regulated process that ensures the exact duplication of the entire genomic DNA followed by division of the cell into two identical daughter cells. If this strict ordering of events is in any way disrupted, the resultant daughter cells would have a different complement of DNA from their parent cell, essentially mutant cells. The cell has established a mechanism to ensure the correct ordering of these crucial events, known as the cell cycle, and mechanisms that can respond ....Cell growth is a tightly regulated process that ensures the exact duplication of the entire genomic DNA followed by division of the cell into two identical daughter cells. If this strict ordering of events is in any way disrupted, the resultant daughter cells would have a different complement of DNA from their parent cell, essentially mutant cells. The cell has established a mechanism to ensure the correct ordering of these crucial events, known as the cell cycle, and mechanisms that can respond to disruptions in this ordering and halt the normal cell cycle mechanism until the fault is rectified. These are the checkpoint controls. Checkpoint controls also respond to environmental stresses such as toxins that can damage the DNA to produce mutations. In diseases such as cancer, these checkpoint mechanisms are often faulty, allowing the cells to accumulate DNA mutations which can ultimately result in the cells becoming the aggresive, malignant tumours associated with the worst forms of this disease. Thus a detailed understanding of the cellular mechanisms involved in normal cell cycle and checkpoint control is important in not only defining the causes of these diseases at a molecular level, but may ultimately provide molecular targets for drugs that specifically destroy cancer cells by targeting the faulty checkpoint control. This proposal will investigate one component of the cell cycle mechanism, cdk2-cyclin A, which also has a major role in checkpoint control, to determine its exact role in both these important cellular growth controls.Read moreRead less
Central to improving the management of patients with cancer is an understanding of the molecular drivers of cancer. Based on our fundamental discoveries about the role of cell growth and perturbed cell signalling as drivers of cancer we will use the integration of molecular and imaging biomarkers with targeted therapies to translate this knowledge into better outcomes for cancer patients with defined molecular drivers of their cancer.
