Overexpression of GSTs is correlated with cancer chemotherapy resistance. One way to counter this phenotype is to use inhibitors. This protocol describes a method using a spectrophotometric assay to screen for potential GST inhibitors. Immunology and Infection Implantation and Monitoring by PET/CT of an Orthotopic Model of Human Pleural Mesothelioma in Athymic Mice Didier J. Colin1, Olivia Bejuy1, Stéphane Germain1, Frédéric Triponez2, Véronique Serre-Beinier2 1MicroPET/SPECT/CT Imaging Laboratory, Centre for BioMedical Imaging (CIBM), Division of Nuclear Medicine and Molecular Imaging, University Hospitals and University of Geneva, 2Division of Thoracic and Endocrine Surgery, University Hospitals and University of Geneva This article describes the generation of an orthotopic mouse model of human pleural mesothelioma by implantation of H2052/484 mesothelioma cells into the pleural cavity of immunocompromised athymic mice. The longitudinal monitoring of the development of intrapleural tumors was assessed by non-invasive multimodal [18F]-2-fluoro-2-deoxy-D-glucose positron emission tomography and computed tomography imaging.
