Mouse models of mesothelioma have led to a greater understanding of the disease and the identification of potential drug therapies some of these have now been translated into clinical trials.

In the existing models, mesothelioma cells that have been grown in the laboratory are transplanted into animals by injecting the cells under the skin. Different cell lines with different properties are used in different experimental protocols. This application will fund the establishment of a central resource to maintain and distribute these cell lines. In addition, we describe a new transgenic mouse model in which mesotheliomas are rapidly induced in the peritoneal cavity after exposure to asbestos, recreating the natural tumour development much more accurately. These mice have been engineered to express the cancer causing protein of a monkey virus (SV40 large T antigen) in their mesothelial cells because it has been suggested that the virus has a role in the development of mesothelioma. This application also seeks funding to use the MexTAg mice to test the usefulness of different therapies for the prevention or treatment of mesothelioma. These animals give us the ability to investigate the disease in a more realistic environment than previous models. In parallel collaborative studies with other groups investigating different aspects of the biology of this cancer, we plan to analyze the earliest changes in the development of the disease and search for early markers using proteomics and gene expression studies. We anticipate that this model will generate information more directly relevant to understanding the human disease and will provide essential experimental data for clinical trials.Read moreRead less

Summary
Recent events have again highlighted influenza�s potential to cause a worldwide pandemic or be used as an agent of biowarfare. As of August 2005, the highly pathogenic Avian Flu sweeping through Asia has infected 112 people, killing 57. Over 150 million chickens have been slaughtered in an attempt to stop its spread, but with infection documented in migratory birds, containment may be difficult if not impossible. Experts believe that it is only a matter of time before the Avian Flu virus is capa ....Recent events have again highlighted influenza�s potential to cause a worldwide pandemic or be used as an agent of biowarfare. As of August 2005, the highly pathogenic Avian Flu sweeping through Asia has infected 112 people, killing 57. Over 150 million chickens have been slaughtered in an attempt to stop its spread, but with infection documented in migratory birds, containment may be difficult if not impossible. Experts believe that it is only a matter of time before the Avian Flu virus is capable of human to human transmission which could result in the deaths of hundreds of thousands of people worldwide. Should a pandemic arise, either through purposely-engineered or natural processes such as avian influenza, effective vaccines are unlikely to be available for at least 3-6 months. In such an event, treatment of infection and prevention of spread through post-exposure prophylaxis would be optimal, while pre-exposure prophylaxis would be most suited to key personnel such as army, medical and emergency-response staff. Biota is a world leading antiviral drug discovery company based in Melbourne, Australia with key expertise in viral respiratory diseases, particularly influenza. Biota developed the first in class neuraminidase inhibitors (NAI) drug, zanamivir (Relenza) and through a partnership with Glaxo Smith Kline (GSK) brought it to market. Biota also developed the FluOIA� for the rapid detection of Influenza A and B. Work has been underway at Biota for some time to develop a new generation of influenza drugs designed to be more active and longer acting than the first generation products. These long acting neuraminidase inhibitors (LANI) have the benefit of less frequent administration and a lower treatment dose making them an ideal choice for stockpiling. The proposed project aims to test the antiviral activity of LANI compound against the H5N1 influenza. The results of which could assist in a decision to fast track the clinical development of the compound with the aim of adding to the national stock pile of antivirals, thus helping Australia to prevent, prepare for and respond to a potential avian influenza-induced pandemic.Read moreRead less
