Summary
This application will define the role of a large cell adhesion molecule, FAT4, in lymphatic vascular development. By understanding how FAT4 functions in lymphatic vessels, we will gain insight to the mechanisms by which mutations in the gene that encodes this protein cause a human lymphoedema syndrome.
Synthesis of substrate analogues for probing catalytic mechanisms and specificity of enzymes involved in the metabolism of plant polysaccharides.

The project is aimed at strengthening collaborations between research groups in Adelaide and France, with the specific objective of synthesizing substrate analogues as probes of enzymatic mechanisms and substrate specificity in polysaccharide hydrolases and synthases of barley. The chemical expertise resides in France, while the enzymatic work will be conducted largely in Australia. Exchange of research staff, particularly at the postgraduate student and research associate levels, is considered essential to capture the benefits of the complementary expertise and to extend an existing international collaboration. The target enzymes are of central importance in cell wall metabolism during development of higher plants.Read moreRead less
Molecular mechanisms of catalysis and the basis of substrate specificity in polysaccharide hydrolases. Reaction intermediates along hydrolytic pathways and molecular determinants of substrate specificity of barley B-glucan exo- and endohydrolases will be defined using crystallographic and kinetic analyses. These enzymes are of central importance in cell wall metabolism during development of higher plants, and in plant-pathogen interactions.

Reaction intermediates along hydrolytic pathways and molecular determinants of substrate specificity of barley B-glucan exo- and endohydrolases will be defined using crystallographic and kinetic analyses. These enzymes are of central importance in cell wall metabolism during development of higher plants, and in plant-pathogen interactions. Realization of the project objectives will not only provide fundamental information on catalytic mechanisms, but will also provide opportunities to manipulate enzyme specificity. Further, site-directed mutagenesis of the enzymes will be used to generate glycosynthases, which will be evaluated for their ability to synthesise novel oligosaccharide and polysaccharide products, some of which might show immunomodulating activity.Read moreRead less

Summary
How do cells sense and react to mechanical forces? There is accumulating evidence that mechanical forces exerted on tissues and cells strongly influences their behaviour. My research aims to understand how cells sense and respond to forces experienced throughout life. Using a combination of three-dimensional cell and tissue culture methods, I will investigate how compressive forces change the biochemistry of cells and their functionality. This work is aimed at generating fundamental knowledge to ....How do cells sense and react to mechanical forces? There is accumulating evidence that mechanical forces exerted on tissues and cells strongly influences their behaviour. My research aims to understand how cells sense and respond to forces experienced throughout life. Using a combination of three-dimensional cell and tissue culture methods, I will investigate how compressive forces change the biochemistry of cells and their functionality. This work is aimed at generating fundamental knowledge to improve our comprehension of how cells respond to force. The expected outcome is a greater understanding of mechanical and biochemical relationships between cells and the environment, to inform fields of tissue engineering of culture scaffolds to better mimic natural cell-tissue settings.Read moreRead less

Infertility, endocrine and metabolic disorders and reproductive cancers are all increasing medical problems and principal contributors to morbidity and mortality in the Australian community. This research takes the novel approach of investigating the mechanisms of dynamic remodeling in reproductive organs. Novel hormonally controlled mechanisms of tissue remodeling unique to reproductive organs and cancers in adults have been discovered. The results are being applied to new medical alternatives for infertile patients and new diagnostics and therapeutics for patients with metastatic cancers. The information is also being applied to improve reproductive efficiency in animal production industries.Read moreRead less
The mechanisms and roles of receptor clustering in cell activation and wound healing by growth factors. Growth factors regulate cell proliferation, migration and differentation by interaction with receptors. Such receptors are usually localized at the cell surface, and require intracellular transduction systems to transmit the signal to the cell interior. We have recently shown the hormone-induced clustering of heterologous hormone receptors in cells, and that this occurs with the co-clustering ....The mechanisms and roles of receptor clustering in cell activation and wound healing by growth factors. Growth factors regulate cell proliferation, migration and differentation by interaction with receptors. Such receptors are usually localized at the cell surface, and require intracellular transduction systems to transmit the signal to the cell interior. We have recently shown the hormone-induced clustering of heterologous hormone receptors in cells, and that this occurs with the co-clustering of downstream signalling molecules at sites of engagement with the extracellular matrix. In addition, we have found that cells presented with an extracellular matrix respond better to subsequent growth factor stimulation. The project aims to determine the cellular mechanisms underlying receptor clustering and the basis of the receptor-extracellular matrix interaction. This will enhance our understanding of growth factor function in a number of conditions, including wound healing. We will extend our in vitro results to the animal model to define parameters for enhanced wound repair.Read moreRead less

This project aims to investigate the role of recently discovered plant cellulose synthase-like CslM genes and to define the polysaccharide product associated with them. Successful identification of the polysaccharide is highly likely to increase our fundamental understanding of how cell walls are made, how cells stick together or fall apart as well as facilitating the training of the next generation of cell wall biologists in challenging molecular and biochemical techniques. This new knowledge could increase our understanding of fruit ripening, and how it might be manipulated. This could have significant downstream commercial benefits if applied to breeding programs of economically important fruit such as grapes, tomatoes and strawberries.Read moreRead less
