Summary
Brain disorders place an economic and social burden on Australia and the personal costs of these illnesses are immeasurable. Several brain abnormalities are caused from the failure of neurons to position themselves in the correct location when the brain develops. Our study aims to discover how neurons move and what factors influence this process. It provides an understanding of normal brain development, as well as providing insight into what may go wrong in the formation of brain diseases.
The Role Of Rnd Genes During Cortical Neurogenesis And Cell Migration

Summary
In order for the brain to function properly, tens of billions of neurons within it first have to be born, then find their proper location before connecting with other neurons in a highly ordered fashion. Failure of these key processes heavily impacts on subsequent brain function, and have been shown to underlie several disorders including epilepsy. This study will investigate how members of the Rnd gene family control cell production and positioning within the developing brain.

Summary
The failure of bone prostheses is becoming a major health problem. More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is becoming more common for young, active in ....The failure of bone prostheses is becoming a major health problem. More than 26,000 hip, and an equal number of knee, replacements were performed in Australia in 2002 with the number increasing between 5%-10% each year for the previous 10 years. Disturbingly, the incidence of revision hip surgery in Australia is now more than 15%, meaning that, despite the impressive success of joint replacement surgery, a significant number of arthroplasties fail. It is becoming more common for young, active individuals to receive joint replacement surgery to improve their quality of life. This, combined with increasing life expectancy, and the known higher rate of failure of joint replacements in younger patients, means that the morbidity of a failed replacement, and the mobidity and associated mortality of revision surgery, will become an increasingly important health issue, with a major impact upon health budgets. The overwhelming majority of hip and knee prostheses have metal or ceramic on polyethylene bearing surfaces. It is now apparent that most implants fail due to bone loss around them leading to loosening, and evidence is accumulating that polyethylene wear particles are a major contributing factor to this process. It is therefore vital that we obtain better understanding of the causes of implant failure in order to extend the life of these implants and this project is designed to do so.Read moreRead less
Cytopathological roles of AMPK in mitochondrial dysfunction. This research project will benefit the Australian community by deepening our understanding of mitochondrial and neurodegenerative diseases. These diseases are incurable and treatment options are limited. The knowledge gained in this project should assist in the development of new or improved treatments. The project will also contribute to the training of young scientists in biomedical research and will enhance Australia's international ....Cytopathological roles of AMPK in mitochondrial dysfunction.

How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understandi ....How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less
Defining a role for non-coding RNAs in gonadal sex differentiation. This project aims to increase knowledge in the area of developmental biology, studying how gene regulation by so-called non-coding RNAs contributes to tissue patterning. The project plans to use a unique model system: gonadal development in the chicken embryo. It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. ....Defining a role for non-coding RNAs in gonadal sex differentiation.

It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. The project aims to provide a deeper understanding of how genes operate to control tissue patterning and organogenesis. It may thus inform the field of sex determination specifically, and, more broadly, stem cell biology and tissue engineering.Read moreRead less
