Maspin (SERPINB5) is accepted as an important tumour suppressor lost in many cancers. Consistent with a critical role in development or differentiation maspin knockout mice die during early embryogenesis, yet clinical data conflict on the prognostic utility of maspin expression. Here to reconcile these findings we made conditional knockout mice. Surprisingly, maspin knockout embryos develop into overtly normal animals. Contrary to original reports, maspin re-expression does not inhibit tumour growth or metastasis in vivo, or influence cell migration, invasion or survival in vitro. Bioinformatic analyses reveal that maspin is not commonly under-expressed in cancer, and that perturbation of genes near maspin may in fact explain poor survival in certain patient cohorts with low maspin expression.

Mouse models for the study of human and animal disease for Australian and international researchers. It has reduced the cost to researchers of accessing mouse models of disease, and provides equipment and expertise to undertake characterization and further research of these models. The APN brought together mouse production, strain storage and pathology capabilities, later extending the core services of the network, and include new services (RNAi and genomics services). Twelve Australian facilities and institutions currently constitute the APN. The APN partners contribute their expertise and infrastructure for the production of mouse models, as well as providing cryopreservation and pathology services. * Walter and Eliza Hall Institute of Medical Research * Monash University * Queensland Institute of Medical Research * Animal Resources Centre * Institute of Medical and Veterinary Science * University of Melbourne * Institute of Molecular Bioscience * Menzies Research Institute * Peter MacCallum Cancer Centre * Australian National University * Western Australian Institute of Medical Research * Centenary Institute In addition, the APN is working with the Atlas of Living Australia to develop a framework for Australia''''s e-science infrastructure to improve the capture, annotation and dissemination of research data. The APN''''s core expertise and infrastructure is also extended by key national and international partnerships. These include the Garvan Institute, the National Institutes of Health (United States), the Wellcome Trust (United Kingdom), and the University of Manitoba (Canada). Services * ES Cell to Mouse: Create a mouse model from embryonic stem cells * RNAi: Screen full genomes to identify novel gene targets * ENU Mutagenesis - Produce chemically-induced mouse models * Pathology - Investigate mouse models using clinical and histopathology * Genomics - Further mouse mutant identification via new discovery pipeline * NHMRC Australian PhenomeBank - a non-profit repository of mouse strains used in Medical Research.
