Summary
We have developed a novel animal model by which to study arthritic disease caused by insect-transmitted viruses known as arboviruses. The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal.

The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal. The production by our immune systems of soluble mediators (cytokines-chemokines) and antibodies is an overwhelming positive aspect of our physiological response to infection by microbes. Protection from disease by these immune compounds can happen naturally, or the body's ability to produce these factors can be exploited to our benefit via the administration of vaccines. However, these factors can also be detrimental to the host contributing to severe disease. For instance, work performed almost 40 years ago showed for the first time that under particular conditions, antibodies against viruses can enhance infection, instead of inhibiting infection as normally seen. In the intervening years work by scientists all over the world has associated antibody-dependent enhancement (ADE) of infection to many types of viruses; ADE is even thought to be a risk factor to serious disease with dengue virus, and has been shown in vitro for the AIDS virus and Ebola virus. We have recently discovered a molecular mechanism which explains how antibody enhances viral infection in vitro. In studies on immune cells infected with Ross River Virus (RRV) we found that infection helped by antibody resulted in the specific disruption to the production of cellular chemicals which are toxic to viruses. Are these mechanisms of antibody-enhanced infection also found in animals? Will such mode of infection cause enhanced disease and tissue pathology (arthritis) in animals?Read moreRead less
Rubisco for all climates: unlocking the enzyme's structure-function relations for more efficient photosynthesis. This projects biotechnological research will identify structural features in the carbon dioxide (CO2)-capturing enzyme from plants that improve its performance, particularly at warmer temperatures. This knowledge is vital for predicting the influence of climate change on crop productivity and paving the way for supercharging photosynthesis to boost crop performance.

Summary
An electrophysiological insight into the role of chloroplasts in stomatal drought signalling. Drought implies a range of stresses with which plants have to cope. Drought is not only a domestic issue for Australian people who live in this dry continent but also significantly affects global food supply and drives climate change. Stomata guard cells exert major controls on global water and carbon cycles. Although the total stomatal pore area may be five per cent of a leaf surface, transpirational w ....An electrophysiological insight into the role of chloroplasts in stomatal drought signalling. Drought implies a range of stresses with which plants have to cope. Drought is not only a domestic issue for Australian people who live in this dry continent but also significantly affects global food supply and drives climate change. Stomata guard cells exert major controls on global water and carbon cycles. Although the total stomatal pore area may be five per cent of a leaf surface, transpirational water loss through the stomata contributes to 70 per cent of total agricultural water usage. As an environmental signal, drought regulates stomatal movements. This project seeks to understand the mechanisms of drought induced molecular retrograde signals and their regulation over stomata. The outcomes will aid the development of strategies for reducing water loss from crops.Read moreRead less
Melanotransferrin: A “Missing Link” And A Novel Pharmacological Target For Treatment

Summary
Despite >30 years of research, the precise function of the protein, melanotransferrin (MTf), is unknown. However, we have breakthrough evidence that MTf stimulates WNT signalling as a major driver in cancer progression. We will investigate this hypothesis, which will underpin new cancer therapies. Indeed, we designed a new class of drugs that target the WNT pathway via up-regulating the WNT inhibitor, NDRG1. This drug (DpC) inhibits MTf expression to block tumour cell growth and metastasis.

The primary benefits are contribution to Australia's knowledge base and raising the profile of functional genomics in Australia, with the research priority of Frontier Technologies for Building and Transforming Australian Industries and priority goals in Breakthrough Science and Frontier Technologies. This project focuses on important biological questions surrounding gene regulation and sex chromosome evolution. International attention has already resulted in genome characterization of Australian icons (wallaby, Tasmanian devil and platypus), more research on these, and other Australian animals, will further highlight the importance of Australian fauna and impact positively on our scientific profile.Read moreRead less

The primary benefits are contribution to Australia's knowledge base and raising the profile of functional comparative genomics in Australia, with the research priority of 'Frontier Technologies for Building and Transforming Australian Industries' and priority goals in 'Breakthrough Science and Frontier Technologies'. This project addresses fundamental questions about the evolution of mammalian X-chromosome inactivation, of importance as a model for epigenetic change, and sex chromosomes, which has engaged some of the greatest genetic minds over nearly a century. Therefore my results will attract wide international interest and impact positively on Australia's scientific profile, and further highlight the importance of Australian mammals.Read moreRead less

The enormous amounts of data that emerge from such research are highly complex, but they hold the key to understanding how biological organisms change over time. Our research will untangle that data to answer fundamental, unanswered questions in modern science: How did the animal groups originate? How are they related to each other? How is biodiversity changing? The answers to these questions and the new analytical tools we will develop will put Australia firmly on the international "map" of Bioinformatics.Read moreRead less

Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
