Summary
Cancer is a major health problem around the world. Currently used treatment options of cancer have the drawback that they also damage healthy tissues. This limits the dosages that can be administered, frequently resulting in treatment failure. Anti-tumour killer T cells are a naturally occurring cell type that can cause tumour regression. In the present proposal, we explore how the efficiency of these cell-types can be further enhanced to induce rejection of progressing tumours.
Using MiR-200 To Find New Therapeutic Targets For Neuroblastoma

Summary
Neuroblastoma is one of the most common cancers in children. We have found that a genetic regulator, called microRNA, can limit the ability of neuroblastoma cells to invade surrounding tissues and metastasise. We aim use the microRNAs to find new therapeutic targets that may work in combination with existing treatments, reducing the short term toxicity and long term deleterious effects of current treatments.
Uncover How Myosin-6 Underpins The Ca2+-dependent Recruitment Of Secretory Vesicles To The Cortical Actin Network

Summary
Neuronal communication relies on the process of exocytosis by which neurons release a neurotransmitter. Exocytosis underpins processes such as the simplest muscle movement to complex tasks such as learning and memory, and is altered in several neurodegenerative pathologies. We will investigate how the protein Myosin-6 controls exocytosis. This research will be important for understanding how neurons communicate in health and disease and will be relevant to other processes such as insulin release ....Neuronal communication relies on the process of exocytosis by which neurons release a neurotransmitter.

Molecular Dissection Of The Actin Cytoskeleton In Exocytosis Using Intravital Microscopy

Summary
The proteins actin and tropomyosin form networks in cells that are involved in all of the key processes that are hijacked when a cell becomes cancerous. We discovered that the tropomyosin is the key to the function of a network and have developed drugs that target the cancer-associated tropomyosin. We will examine how the drugs kill cancer cells using a novel method, developed by us, to visualize drug activity in real time, and validate their impact on the target filaments in living tissue.
Regulation Of Mesenchymal To Epithelial Transitions By Netrin Receptors

Summary
The formation of 2D cellular sheets is important during development, tissue repair, and tumor growth. The mechanisms involved, however, remain largely unknown. Recent findings in the fly and in human cells suggest Frazzled/Neogenin receptors drive this process, by establishing polarised scaffolds in the cell. We will test this hypothesis using fly genetics and analysis of 3-dimensional culture of mammalian cells. Our results will help guide future therapies for human disease.
Targeting The Synaptic Actin Cytoskeleton In Alzheimer's Disease

Summary
Dementias have become one of the fastest growing sources of major disease burdens in developed countries with about one in fifteen Australians older than 65 being affected. We will study how pathological stimuli disrupt nerve cell connections in the brain by impacting on the cellular architecture at these connections. Findings from our study will provide profound new insights in how nerve cells communicate with each other and how this communication is breaking down in disease.
Regulation Of ERK Driven Cell Proliferation By The Actin Cytoskeleton

Funding Amount
$920,972.00
Summary
The cells in your body respond to external signals and control their proliferation by transmitting signals from one part of the cell to another. This has usually been thought to involve the movement of signals through a liquid medium without the involvement of any machinery to control the movement. The project aims to test the role of the architecture of the cells in physically moving a growth signal from one place to another. We think that the architecture involved plays a key role in cancer.
How Caveolae Condition Tissue Mechanics For An Anti-tumor Niche.

Summary
The outcome of cancer is determined not only by the behaviour of the cancer cell, but also by how the normal tissue cells of the body respond to it. This project investigates how tissue cells that surround cancer cells can eliminate early cancers from the body. It develops on newly-discovered mechanisms that allow epithelial tissues to detect and physically expel cancer cells. This mechanism can protect us from cancer, but potentially allow cancer to develop when it fails.
The Role Of LIM Domain Kinase 1 In The Pathogenesis Of Alzheimer’s Disease

Funding Amount

Summary
Alzheimer’s disease is characterized by progressive loss of cognition. Few Australians have remained untouched by the effects of Alzheimer’s disease in their families or social circles. Unfortunately, there is no cure and current therapies are limited to modest symptomatic relief. This project will explore the role of a protein that regulates the structural integrity of brain cells in disease, and test if targeting this protein could prevent disease progression.
Microtubule Stabilisation: Promoting Adaptive Plasticity, Brain Healing And Functional Recovery After Traumatic Brain Injury

Summary
Traumatic brain injury (TBI) continues to be the leading cause of death and disability for individuals under 45 years of age. There are currently no effective pharmacotherapeutics available that are able to prevent or minimise brain damage following TBI. My team will use sophisticated in vivo techniques to fully characterise the brain's response to injury and to test whether microtubule stabilisation via new generation taxol-like drugs improves post-trauma outcomes.
