Summary
This project examines the effect of a novel FosB/AP-1 inhibitor (LK001) on neointima formation after injury in animal models of restenosis, atherosclerosis and abdominal aortic aneurysm, and a human ex vivo model of graft stenosis Given the current prevalence of CVD in Australia and the increasing demographic of susceptible individuals in the ageing population, this project has enormous clinical implications.
Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler so ....Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler solvents on the way to producing cellulose-based polymers. By exploring ways to adjust the properties of celluloses for use in different applications, we can deliver potential benefits to primary producers, industries and the environment.

Control of actin assembly by cell-cell adhesion: molecular effectors and higher order function. Functional cooperation between the actin cytoskeleton and cadherin cell-cell adhesion molecules plays critical roles during development and morphogenesis. This proposal builds on my lab's recent discovery that E-cadherin interacts with and regulates the Arp2/3 actin nucleator complex, a central determinant of actin assembly in cells. We will explore key implications of this finding, concentrating on d ....Control of actin assembly by cell-cell adhesion: molecular effectors and higher order function. Functional cooperation between the actin cytoskeleton and cadherin cell-cell adhesion molecules plays critical roles during development and morphogenesis. This proposal builds on my lab's recent discovery that E-cadherin interacts with and regulates the Arp2/3 actin nucleator complex, a central determinant of actin assembly in cells. We will explore key implications of this finding, concentrating on defining the molecular mechanisms that regulate Arp2/3 and actin assembly in cadherin-based adhesion. Our work combines molecular characterization of regulatory mechanisms and proteomic searches for new regulators, with tests of the higher-order function of this novel process in cell adhesion and recognition.Read moreRead less
Balancing cadherin-actin cooperation: the key regulatory role of Ena/VASP proteins. This project analyses a fundamental mechanism of how cells work together in tissues. Understanding the fundamental mechanisms of how cells work will provide important basic scientific information to enrich the scientific expertise in Australia and its part in the international community, generate insights relevant for understanding human disease and physical degeneration, and support the training of young scienti ....Balancing cadherin-actin cooperation: the key regulatory role of Ena/VASP proteins.

A microscopical examination of curdlan production by an Agrobacterium sp. We will investigate the secretion of the insoluble polysaccharide curdlan, a (1,3)-beta-glucan, from the surfaces of Agrobacterium cells and the assembly of the individual polysaccharide chains into microfibrils. Using state-of-the-art techniques in time lapse and electron microscopy we will compare the images of wild type curdlan-producing cells with those of mutants impaired in the production of curdlan. The outputs will ....A microscopical examination of curdlan production by an Agrobacterium sp. We will investigate the secretion of the insoluble polysaccharide curdlan, a (1,3)-beta-glucan, from the surfaces of Agrobacterium cells and the assembly of the individual polysaccharide chains into microfibrils. Using state-of-the-art techniques in time lapse and electron microscopy we will compare the images of wild type curdlan-producing cells with those of mutants impaired in the production of curdlan. The outputs will be information on the mechanics of curdlan production that will complement that emerging from our molecular biological and biochemical studies. These will have implications for understanding bacterial polysaccharide production in general and may have a commercial outcome in enhanced curdlan production.Read moreRead less
