Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will im ....Molecular genetic analyses of trinucleotide repeat expansions.

These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will improve our mechanistic understanding of genetic diseases in populations. In addition, this proposal is expected to lead to identification of potential targets and technologies that would be of interest to Australian industry.Read moreRead less

Preventing genetic damage with BIX - a novel player in the DNA damage response pathway. Defects in the DNA damage-response pathway underpin many human genetic disorders and diseases, including cancer. A detailed understanding of this process has enormous implications for future medicine. Our characterization of a novel protein involved in DNA damage signalling will help in screening inhibitors of this pathway that could be applied in chemo-and/or radiotherapy.

This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiatives in developmental and cellular biology. This large-scale, high-resolution expression profiling infrastructure is required to maintain international competitiveness and will dramatically improve our gene discovery, functional assessment and understanding of vertebrate development.Read moreRead less

This project is included in the designated priority area of research Promoting and Maintaining Good Health and Ageing Well. It represents a mouse model to assist in the study of human disease. It is the first mouse model for SMG-1, a protein kinase that protects against a variety of different forms of stress. The strength of the model is that it can be combined with other mouse models to interrogate and elucidate the events occurring in different pathways for stress. The expectation is that ground-breaking data will be generated with this model providing scientific leadership on the role of this protein. It will also assist in establishing new collaborations.Read moreRead less
Characterisation of the novel mitochondrial protein (CABC1/ADCK3) and its role in protecting against oxidative stress. This is the first detailed characterisation and mechanistic study on a protein that protects against oxidative stress and neurodegeneration. Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress.

This is the first detailed characterisation and mechanistic study on a protein that protects against oxidative stress and neurodegeneration. Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress. An investigation of this protein presents an opportunity for the investigator to work at the forefront in this field adding to Australia's scientific leadership in the area. It also represents an ideal project for post-graduate training and is a collaboration between groups in Brisbane and Melbourne. Read moreRead less
The function of menin in mammalian development. This project aims to determine the role of a ubiquitous transcriptional co-regulator, menin, in mammalian development. Mice that lack menin through targeted deletion of the gene die during embryogenesis, but the cause is unknown, although is likely to be due to the abnormal expression of genes usually regulated by this factor. We will determine which genes are inappropriately expressed and responsible for the accompanying developmental defects. Thi ....The function of menin in mammalian development.

Mice that lack menin through targeted deletion of the gene die during embryogenesis, but the cause is unknown, although is likely to be due to the abnormal expression of genes usually regulated by this factor. We will determine which genes are inappropriately expressed and responsible for the accompanying developmental defects. This knowledge will help us understand the process of development in mammals, including birth defects in humans.Read moreRead less

The immediate outcomes of the proposed research will be in fundamental knowledge and understanding of important cellular and biological processes in which the Schlafen genes are involved. In particular, Schlafen genes are likely to play a role in inflammatory responses and in blood cell growth. These process clearly have relevance to a range of major human (and animal) diseases including infectious disease, auto-immune disease and leukaemia, and thus a long-term outcome may be improved treatments for such disease.

Recently, we cloned a gene, Sat1, expressed in mouse liver and kidneys, which may be responsible for body sulfate maintenance. In this study, we will determine the physiological importance of Sat1 in cell growth/survival and in controlling body sulfate levels. We will generate and characterise a Sat1 lacking mouse, study its expression during development and its effects on other genes. We will elucidate how body sulfate levels are maintained and its importance in cell growth/development.Read moreRead less
