Brief description 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.
