Studies in cancer control. As life expectancy in Australia (and throughout the world) continues to rise, so will the burden of cancer escalate. Treating cancer after diagnosis is costly, and in many instances, unsuccessful. Preventive strategies promise to reduce the future cancer burden, yet our knowledge in this arena is limited by the lack of credible research as to what works and what does not. This application addresses this gap directly by conducting research into the control of two cancer ....Studies in cancer control. As life expectancy in Australia (and throughout the world) continues to rise, so will the burden of cancer escalate. Treating cancer after diagnosis is costly, and in many instances, unsuccessful. Preventive strategies promise to reduce the future cancer burden, yet our knowledge in this arena is limited by the lack of credible research as to what works and what does not. This application addresses this gap directly by conducting research into the control of two cancers which exact a growing toll in Australia and elsewhere. The work seeks to identify and understand the causal pathways to cancer, and then use this information to devise evidence-based strategies for cancer control.Read moreRead less
Activation mechanisms of store-operated calcium channels in liver cells. Currently, one of the most active areas of research in biology involves the molecular mechanisms that control the activity of cells. Defining these will provide a deeper understanding of normal function and disease, and provide potential therapeutic targets. This group has an international reputation for its work and it makes a major input to maintaining Australia as a significant contributor to this field. While its resea ....Activation mechanisms of store-operated calcium channels in liver cells. Currently, one of the most active areas of research in biology involves the molecular mechanisms that control the activity of cells. Defining these will provide a deeper understanding of normal function and disease, and provide potential therapeutic targets. This group has an international reputation for its work and it makes a major input to maintaining Australia as a significant contributor to this field. While its research has broad application in biology, its specific focus, calcium signalling in the liver, will provide the basis for understanding liver function and disease and, potentially, for developing new treatments for liver disease associated with abnormal calcium homeostasis.Read moreRead less
Three-dimensional structures, substrate specificities and catalytic mechanisms of polysaccharide synthases. Plant wall polysaccharides are extensively used for food and fibre, and are important dietary components in human nutrition. A precise knowledge of mechanisms used by plants to synthesize these polysaccharides is unavailable, but would reveal potential routes to manipulate their biosynthesis in important crop species. For example, the levels or structures of polysaccharides might be modif ....Three-dimensional structures, substrate specificities and catalytic mechanisms of polysaccharide synthases. Plant wall polysaccharides are extensively used for food and fibre, and are important dietary components in human nutrition. A precise knowledge of mechanisms used by plants to synthesize these polysaccharides is unavailable, but would reveal potential routes to manipulate their biosynthesis in important crop species. For example, the levels or structures of polysaccharides might be modified to improve their efficacy as anti-cancer agents in human diets, to enhance digestibility of animal stock feeds, or to synthesise pharmologically valuable compounds. Thus, economic, social and environmental benefits will flow to both producers and consumers. Read moreRead less
Molecular signals that regulate the regenerative properties of intestinal epithelial cells. Most cancer deaths are due to the cancer spreading to other organs. Cancer is much more difficult to treat once it has spread to other organs in the body where the cancer cells can exist in a dormant state. Dormant cancer cells evade conventional anticancer treatment and can remain dormant for a very long time before they change back to a 'tumour-growing' state. An understanding of how the cancer initiati ....Molecular signals that regulate the regenerative properties of intestinal epithelial cells. Most cancer deaths are due to the cancer spreading to other organs. Cancer is much more difficult to treat once it has spread to other organs in the body where the cancer cells can exist in a dormant state. Dormant cancer cells evade conventional anticancer treatment and can remain dormant for a very long time before they change back to a 'tumour-growing' state. An understanding of how the cancer initiating (stem cell) property of tumour cells is maintained offers potential novel avenues to eliminate persistent cancer cells. This knowledge will ultimately lead to better management and treatment of cancer, and increase survival. An understanding of stem cell behaviour is also central to the control of degenerative conditions.Read moreRead less
Electrical activity in early enteric neuron development. Intestinal movements and secretion are critical to the good health and nutrition of both humans and animals. These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells. This is will provide an important base for more applied research aime ....Electrical activity in early enteric neuron development. Intestinal movements and secretion are critical to the good health and nutrition of both humans and animals. These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells. This is will provide an important base for more applied research aimed at developing treatments for diseases like chronic constipation and irritable bowel syndrome. It will also contribute to the growing knowledge about how epigenetic factors can modify genetically programmed development within the nervous system.Read moreRead less

Wide-ranging research outcomes of national and community benefit include imaging tumour development, bone metabolism (osteoporosis), neural function (Alzheimer's disease) and regeneration, and infection mechanisms in live animals, which will result in improvements in human health. Imaging and monitoring coral growth, fish age, and soil structure will improve the economics and sustainability of Australia's marine ecosystems and agricultural food production.Read moreRead less
Amino acids as nutrients - the molecular basis of amino acid absorption in kidney and intestine. Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face. Most studies in nutrition focus on fat and carbohydrates because of their direct involvement in obesity and diabetes. Proteins and the resulting peptides and amino acids, however, form 10-15% of our nutritio ....Amino acids as nutrients - the molecular basis of amino acid absorption in kidney and intestine. Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face. Most studies in nutrition focus on fat and carbohydrates because of their direct involvement in obesity and diabetes. Proteins and the resulting peptides and amino acids, however, form 10-15% of our nutrition. At a time where protein-rich diets are recommended to fight obesity and diabetes, it is important to understand the basis of protein absorption and metabolism. This project investigates the mechanism and mediators of amino acid absorption in kidney and intestine. Read moreRead less
The role of retinoic acid signalling in the development of the oesophageal epithelium. Oesophageal adenocarcinoma (OAC) is a disease with increasing incidence. The majority of patients with OAC are diagnosed when the cancer is at a late stage and therefore treatment options are limited, meaning the disease is almost invariably fatal. OAC arises from the precancerous condition, Barrett's oesophagus, which occurs as a consequence of chronic reflux, although the key processes driving its developmen ....The role of retinoic acid signalling in the development of the oesophageal epithelium. Oesophageal adenocarcinoma (OAC) is a disease with increasing incidence. The majority of patients with OAC are diagnosed when the cancer is at a late stage and therefore treatment options are limited, meaning the disease is almost invariably fatal. OAC arises from the precancerous condition, Barrett's oesophagus, which occurs as a consequence of chronic reflux, although the key processes driving its development are unknown. This project aims to better understand the critical first step in the progression to cancer and thus expand the scope for the development of therapies, particularly those aimed at early intervention, and tools that predict progression.Read moreRead less

Scymnol and its sulfate are natural therapeutic products from shark bile with highly potent anti-oxidant and liver-protective activities. The Industry Partner and Macrides have co-patented the synthesis of scymnol to avoid using scarce natural resources. However, unresolved problems in scale-up of production have prevented them from supplying the growing demands of cosmetic and health food companies. Our research group has recently developed a potential synthetic route for scymnol sulfate. The present project aims to develop a commercially-viable scale-up of this synthesis for manufacturing scymnol and scymnol sulfate to solve current supply problems; and to provide essential safety information for their appropriate use; and evaluate potential new therapeutic uses.Read moreRead less
