Summary
Inherited skeletal disorders are a significant disease burden. Many gene mutations have been defined but we only have limited understanding about how they cause the disease. We will use patient skin cells and new in vitro re-programing technology to induce them to form cartilage cells to produce “disease in a dish” models of human skeletal disorders. These models will allow us to answer questions about how specific mutations cause disease and identify potential therapies

Summary
Muscular dystrophy is a devastating childhood disorder. There is no cure and no effective therapy to stop the disease progressing to early death. Our pilot data show that muscular dystrophy in a mouse model is dramatically improved when the Adamts5 gene is inactivated. ADAMTS5 is an enzyme that remodels the extracellular matrix around cells. This suggests that inhibiting ADAMTS5 may be a new way to treat muscular dystrophy. We will test this idea in mice with muscular dystrophy
Functional Genomic Analysis of Exported DNAJ Molecules in the Malaria Parasite Plasmodium falciparum. Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria. The project will translate recent genomic data into functional insights using frontier technology t ....Functional Genomic Analysis of Exported DNAJ Molecules in the Malaria Parasite Plasmodium falciparum. Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria. The project will translate recent genomic data into functional insights using frontier technology to identify new intervention targets for P. falciparum infection. Developing novel targets is mandated by humanity, and also to safeguard Australia's region against the social and economical implication of this disease. An Australian developed intervention would increase the global visibility of its science, leading to increased investments.Read moreRead less
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
Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

A Structural Investigation Into Events Within The Immunological Synapse. The proposed research program, using laboratory-based and synchrotron-based radiation, will provide significant fundamental insight into the processes that control infection. Investigating processes central to immunity is important, as it will further our understanding of these critically-important events. Such knowledge will increase Australia's international research standing, as well as having the potential to generat ....A Structural Investigation Into Events Within The Immunological Synapse.

Filamentous fungi are responsible for many major plant diseases that result in devastating crop losses and food spoilage world wide. Currently there are no resistant cultivars or adequate chemical controls for many of these diseases. The plant defensin, NaD1, stops the growth of many pathogens, including the recalcitrant fungi Fusarium oxysporum and Botrytis cinerea, and has been shown to protect transgenic cotton against fungal infection in glasshouse and field trials. NaD1 has potential application for durable, broad spectrum fungal disease control in crops. This will lead to both environmental and economic benefits to Australia. Read moreRead less

The molecular basis of endothelial mechanotransduction through TRPV4. This project aims to understand how blood flow dynamics coordinate the plasma membrane localisation and interaction of the transient receptor potential vanilloid 4 (TRPV4), a candidate mechanosensitive ion channel broadly expressed in endothelium with physiological and pathological roles in the cardiovascular system, with other mechanoreceptors and the physiological relevance of these events.

This project aims to understand how blood flow dynamics coordinate the plasma membrane localisation and interaction of the transient receptor potential vanilloid 4 (TRPV4), a candidate mechanosensitive ion channel broadly expressed in endothelium with physiological and pathological roles in the cardiovascular system, with other mechanoreceptors and the physiological relevance of these events. Blood flow haemodynamics affect cardiovascular health and morphogenesis. This project will highlight the role of TRPV4 channels in the short- and long-term adaptive responses to shear stress and will also have significant potential for application in future drug discovery.Read moreRead less
Symbiotic partnership between algae and animals that powers coral reefs.

Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted.

This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how the alga gives them food, and how the animal hosts regulate growth of their algae to optimise food production but avoid being overrun by algae. Understanding the partnership that drives reef growth and survival may better equip us to protect this threatened resource.Read moreRead less
