In this Australian-led Kangaroo Genome Project, we will map and characterize the tammar wallaby genome at the molecular level. Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the whole genome as large inserts in BAC vectors, and build a "golden path" with minimal overlap. We will construct libraries of expressed genes from tammar tissues and array them for use in analysing gene expression.Read moreRead less

Skeletal muscles represent the largest organ in the body of vertebrates and are responsible for major functions including maintaining posture and locomotion. Skeletal muscles are also a major source of heat production. The project focuses on temperature-induced effects on the ability of the skeletal muscle to contract in warm blooded animals, including marsupials, and on the complex roles played by a cellular structure unique to the muscle fibre, the tubular system, with respect to regulation of muscle function at physiological temperatures. The project will test hypotheses that will have far-reaching implications for muscle physiology, cell biology and evolutionary biology.Read moreRead less
Oxidative stress-induced alterations of the host erythrocyte by the malaria parasite. The malaria parasite spends part of its lifecycle inside the red blood cells of its host. During this time, the parasite modifies many of the features of the red blood cell and subjects it to high levels of oxidative stress. We will use and develop a variety of fluorescence and microscopic techniques to understand the molecular basis of the alterations in the organization of membrane proteins in malaria parasit ....Oxidative stress-induced alterations of the host erythrocyte by the malaria parasite. The malaria parasite spends part of its lifecycle inside the red blood cells of its host. During this time, the parasite modifies many of the features of the red blood cell and subjects it to high levels of oxidative stress. We will use and develop a variety of fluorescence and microscopic techniques to understand the molecular basis of the alterations in the organization of membrane proteins in malaria parasite-infected red blood cells. We will examine the roles of oxidative stress and of parasite proteins in modulating the properties of the host cell membrane.Read moreRead less

Probing membrane rafts using surface-selective multi-dimensional microscopy. The results of this project will provide fundamental insights into the role played by domains in cell membranes in the regulation of membrane protein function. These insights will create new avenues in the biotechnology industry for development of novel therapeutics aimed at disruption of membrane protein-protein interactions that cause aberant cell signalling in disease states such as cancer.
Statistical methods for detection of non-coding RNAs in eukaryote genomes. Understanding how eukaryotic cells work is a major goal of 21st century biology. A crucial step will be to catalogue the functional components of eukaryotic genomes.

Understanding how eukaryotic cells work is a major goal of 21st century biology. A crucial step will be to catalogue the functional components of eukaryotic genomes. Australian researchers must be involved in this process at an early stage, in order to maximise commercial opportunities, attract quality researchers and position ourselves for further advances. This project will make major contributions to international efforts in this area, via the development of statistical methods for segmenting genomes, classification of those segments, and study of the resulting classes. In the long term, enhanced understanding of eukaryotic cells will lead to breakthroughs in biology, and to medical, pharmaceutical, agricultural and scientific advances.Read moreRead less

The secretory pathway of eukaryotic cells is fundamental for proper cell growth. The Golgi apparatus is a key organelle of this pathway where newly made proteins are selectively packaged into membrane-bound transport vehicles and then shipped to their correct destination, such as the surface of the cell. This research aims to understand the mechanism by which these cargo-loaded transport vehicles are generated from the Golgi apparatus. This information is of fundamental importance in understanding how a cell survives and grows, and is necessary to allow a rational basis for the engineering of secreted recombinant molecules.Read moreRead less
The role of omega-3 fatty acids in brain mechanisms that regulate water and salt balance. The ability of mammals to survive is heavily dependent upon their ability to maintain body fluid balance.

The ability of mammals to survive is heavily dependent upon their ability to maintain body fluid balance. This project aims to elucidate brain mechanisms for the behavioural regulation of water and salt balance, with specific investigation of the role of dietary fatty acids within these processes. It is hypothesised that omega-3 polyunsaturated fatty acids (PUFA) affect intake of water and salt by affecting the sensitivity of various receptors, or the hormones used by this body system. Omega-3 PUFA are known to play a role in regulating genes, and therefore, may also affect the production of key proteins, such as receptors, hormones or enzymes involved in the regulation of salt and water intake.Read moreRead less
