Phasevarions of Haemophilus influenzae: mechanisms and origins of a novel epigenetic system controlling coordinated random switching in expression of multiple genes. Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics.

Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics. Our recent work has identified a new genetic system, the 'phasevarion', that mediates random expression of multiple genes. The proposed research aims to advance our understanding of gene expression at the most basic level, revealing how bacteria generate diverse populations to evade environmental and immune stresses, and facilitating improved interpretation and use of DNA sequences for researchers and industry in this field.Read moreRead less
Evolution of nervous system patterning processes: characterisation of homologs of key Drosophila regulatory genes from the coral Acropora. Defining the common mechanisms of nervous system development is one of the major goals of modern biology, but is presently being addressed largely by comparisons between a few very advanced (and therefore specialised) animals. Comparative data from a lower animal is urgently needed, and will clarify many aspects of nervous system evolution and development. Th ....Evolution of nervous system patterning processes: characterisation of homologs of key Drosophila regulatory genes from the coral Acropora. Defining the common mechanisms of nervous system development is one of the major goals of modern biology, but is presently being addressed largely by comparisons between a few very advanced (and therefore specialised) animals. Comparative data from a lower animal is urgently needed, and will clarify many aspects of nervous system evolution and development. The pioneering work carried out on Acropora in this laboratory suggests that it is perhaps the best choice currently available for this purpose. This project will use Acropora to address fundamental questions about the evolution of nervous system developmental processes.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.

Summary
A proteomics facility for Queensland researchers. The successful completion of sequencing of the genomes of many organisms, including man, has thrown emphasis back on the identification of proteins involved in the complex events that sustain cellular life. Our aim is to set up a world-class facility for proteomics research which will allow a large cohort of scientists at several institutions to identify individual proteins in vanishingly small samples of very complex mixtures. This facility wi ....A proteomics facility for Queensland researchers. The successful completion of sequencing of the genomes of many organisms, including man, has thrown emphasis back on the identification of proteins involved in the complex events that sustain cellular life. Our aim is to set up a world-class facility for proteomics research which will allow a large cohort of scientists at several institutions to identify individual proteins in vanishingly small samples of very complex mixtures. This facility will enable investigation of the control of gene expression, the intricate organisation of proteins within cells, and proteins which are potential drug targets. This equipment is an essential resource for Queensland research groups.Read moreRead less
Pre-clinical evaluation of snake venom proteins with therapeutic potential. Australia harbors some of the most toxic snakes in the world. Their venoms contain a range of substances that are designed to rapidly immobilize and kill their prey. These include agents that lead to enhanced blood clotting; excess bleeding. We have isolated and characterized a large number of the components involved over the last several years. The aim here is to carry out pre-clinical trials in animal models to test th ....Pre-clinical evaluation of snake venom proteins with therapeutic potential. Australia harbors some of the most toxic snakes in the world. Their venoms contain a range of substances that are designed to rapidly immobilize and kill their prey. These include agents that lead to enhanced blood clotting; excess bleeding. We have isolated and characterized a large number of the components involved over the last several years. The aim here is to carry out pre-clinical trials in animal models to test the efficacy of three proteins as anti-bleeding agents and investigate several other novel components. The ultimate outcome will be the development of novel drugs that will have application in the treatment of human disorders. 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. An investiga ....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. 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
