Summary
When breast cancer spreads to other organs, it results in high morbidity and mortality. MicroRNAs are a class of genes that control the expression of other genes, some of which are involved in the spread of cancer. In this project we will examine the function of two microRNA species that we have found to be associated with breast cancer spread. The anticipated outcome is a better knowledge of the genes that control cancer spread and the identification of new molecular targets for therapy.
Targeting Drug-Resistance In Paediatric Acute Lymphoblastic Leukaemia

Summary
Leukaemia is the most common type of cancer in children but resistance to therapy continues to be a significant problem. This project will investigate the biology of drug-resistance and relapse using a mouse model that replicates the human disease. We hope to identify novel therapeutic targets that can be used in combination with existing therapies to improve outcomes in this disease, particularly for patients that develop drug-resistance such as those at the time of relapse.
The Role Of Neuronal Nicotinic Receptor Subunits In The Self-Administration And Relapse To Alcohol Seeking:Treatments For Alcohol Dependence

Summary
The World Health Organization reports that alcohol causes almost two million deaths every year and results in physical disability or shortened life span for at least 58 million others. Despite the fact that addiction represents more than 40% of brain-related illnesses, there is a dearth of innovative treatments. The overall goal of my research is to develop more effective medications for the treatment of alcohol use disorder by targeting the neuronal nicotinic receptor subtypes that have been sp ....The World Health Organization reports that alcohol causes almost two million deaths every year and results in physical disability or shortened life span for at least 58 million others. Despite the fact that addiction represents more than 40% of brain-related illnesses, there is a dearth of innovative treatments. The overall goal of my research is to develop more effective medications for the treatment of alcohol use disorder by targeting the neuronal nicotinic receptor subtypes that have been specifically altered by heavy alcohol intake.Read moreRead less
An International Clinical Trial To Evaluate New Therapies To Improve Survival Of Children With Relapsed Acute Lymphoblastic Leukaemia

Funding Amount
$1,567,500.00
Summary
Children who relapse with childhood leukaemia have only a 50% chance of being alive after 5 years. We will participate in a new international trial involving most European and all Australian and New Zealand childhood oncology centres, to test the effectiveness of promising new treatments and to perform biological studies which should enable doctors in future to pick the best treatment for each of these patients.
Vitamin D Synthesis Within Osteoblasts Increases Bone Mineral By Regulating Remodelling: Is This The Link Between Vitamin D Status And Fractures?

Summary
This project will contribute to understanding mechanism of vitamin D action within bone to modulate bone resorption and offers the exciting prospect of identifying the mechanism by which an adequate vitamin D status can reduce the risk of osteoporotic hip fractures. Thus, this project has great potential to improve community health by being able to recommend vitamin D supplementation made on the basis of maintaining normal bone cell function with psarticular reference to modulating bone resorpti ....This project will contribute to understanding mechanism of vitamin D action within bone to modulate bone resorption and offers the exciting prospect of identifying the mechanism by which an adequate vitamin D status can reduce the risk of osteoporotic hip fractures.

Identifying Novel Antimalarial Targets Using ENU Mutagenesis In The Mouse

Funding Amount

Summary
Malaria is estimated to cause 1.2 million deaths per year. The malarial parasite has developed resistance to most drugs and new drugs are needed. We aim to mimic the protective red blood cell diseases common in human populations in malarial endemic areas by identifying host targets that are important in parasite growth.
Elucidating The Role Of MiR-196 In Formation Of The Axial Skeleton

Funding Amount
$520,087.00
Summary
Exquisite regulation of gene expression is a fundamental principle underlying growth and development of an embryo as well as homeostasis in the adult. Following the identification of hundreds of microRNAs within the genome which act to modulate gene expression, the challenge and the goal of these studies, is to identify individual microRNAs which contribute significantly to bone formation in the developing embryo.
Molecular Regulation Of Pluripotency In The Mammalian Germline

Funding Amount

Summary
Germ cells generate sperm in males or oocytes in females. In males, germ cell numbers are tightly controlled in the embryo, with too few germ cells causing infertility, and unrestrained germ cell numbers leading to testicular cancer. We have discovered a molecular mechanism that regulates germ cells in the embryo, and propose to study in mice how this regulation is accomplished and the consequences of defective regulation, in order to learn more about how infertility and testis cancer arise.
A New Animal Model Of The Prodrome In Schizophrenia. Enhanced Dopamine In Prodromal Schizophrenia (EDiPs)

Summary
Psychiatrists now recognize a pre-symptomatic stage is present in people at risk of developing schizophrenia. Using new brain imaging techniques we now know that some of these individuals have changes in a major neurotransmitter, dopamine, prior to being diagnosed. We have developed a new model in animals, which recreates these exact same changes at a comparable age. We want to now understand what are the broader effects in the brain and try and block these changes in dopamine with new drugs.
The cross-disciplinary team performing this research will examine how mobile DNA elements found in brain cells move in response to learning and memory exercises in mice, and whether these changes generate an address system for parts of the brain to be turned on by specific experiences. This work has major implications for our fundamental understanding of how the brain works in healthy individuals, as well as people affected by neurodevelopmental and neurodegenerative conditions.
