Summary
Genes contain the information to build our body and keep it operating normally. These genes are inherited from our parents and number around 100,000. Faults in these genes can cause inherited diseases such as cystic fibrosis, cancers and common disorders such as Asthma and diabetes. These genes need detecting so that particular genes can be identified as causing the disease and also so that patients can have their disease properly diagnosed so that proper therapy and information can be given to ....Genes contain the information to build our body and keep it operating normally. These genes are inherited from our parents and number around 100,000. Faults in these genes can cause inherited diseases such as cystic fibrosis, cancers and common disorders such as Asthma and diabetes. These genes need detecting so that particular genes can be identified as causing the disease and also so that patients can have their disease properly diagnosed so that proper therapy and information can be given to the patients. In future similar changes (but changes not causing disease) may be searched for in patients to overcome the side effects of drugs. Our centre specializes in the methods of detecting faults and their application. Two of our methods are being used around the world and one is being sold as simple kit. These methods still have drawbacks and the work proposed is to overcome some of these. We propose to apply our and other methods to faults in genes which have recently been shown to cause diseases of the artery. This is an exciting new development that shows that this disease is similar to cancer. We are fortunate to have attracted Dr Paula Bray from the laboratory which discovered this. This new finding needs to be studied in more detail and may identify life-style factors which cause coronary heart disease. Our studies will also assist in gene therapy when it becomes available.Read moreRead less

Such research projects are inhibited due to the complexity of the current methods. Current methods are complex and expensive, especially looking for a possible fault, due to what is called a preparation step on complex and expensive equipment. We will develop and commercialise a simpler test because separation is avoided.Read moreRead less
The rapid interactions of circulating human blood platelets is critical to prevent bleeding, but can cause thrombotic diseases (heart attack, stroke). These highly regulated interactions involve specific adhesive proteins. Our studies will define factors regulating platelet interactions. Imaging the thrombotic process will quantify platelet function at an unprecedented resolution and we have a panel of new candidate reagents that will be assessed for antithrombotic potential.
Unraveling the variability in the protein expression in tissues or cell populations is critical to understand how cells respond to their environment. For example, this can provide details about the cellular response to an infection or to a chemoterapic. As of today, single cell protein analyses has become at reach, but its application is still cumbersome and its throughput is low. This proposal aims to develop and deploy a simple and robust method to analyse the protein content in single cells.

Mutagenesis during the production of sex cells is a fundamental biological process and the cause of inherited human disorders.

These disorders span the entire spectrum of diseases that have a genetic component, such as autoimmune diseases and cancers, therefore influencing all age groups. A better understanding of the mechanisms underlying this process is a priority since it is the essential knowledge required for understanding all of the factors that contribute to this array of debilitating diseases, and for devising effective preventative and diagnostic measures. To attain this understanding necessitates establishing the mechanistic origins of germline mutagenesis. Two basic approaches are employed to understand this process. The first assesses the incidence of mutation in pedigrees. This identifies the spectrum of risk mutations underlying the specific disease surveyed. Because other biological processes also influence these observations, the results from this approach do not reflect the underlying germline mutation spectra and are therefore not translatable between diseases. As mutations are rare events, it is prohibitive to obtain sufficient observations to resolve the underlying mechanisms. The second approach employs comparative genomic data, and uses differences in germline biology to estimate sex-biased effects. This comparative approach benefits from the accumulation of mutations over vast periods of time. The approach has not, however, been applied to diagnose the mechanistic origins of mutations. In this project, we will apply the enormous volume of comparative sequencing data to relate components of the mutagenic spectrum with sexual differences in germline biology. The project will differentiate between different types of mutations, and their association with specific processes will be established. The results will be a determination of the relative contributions of different mechanisms of mutation to germline mutagenesis.Read moreRead less

Summary
The aim of this project is to establish an evidence-based approach to business preparedness for pandemic influenza. We will identify key areas of vulnerability in small and medium-sized businesses which can be targeted to enhance preparedness for pandemic influenza, and thus contribute to control of the spread of pandemic influenza in the community.
