Abstract
Gene therapy and virotherapy are one of the approaches used to treat malignant pleural mesothelioma. To improve the efficiency of targeting malignant mesothelioma cells, we designed a novel system using the promoter of the CREBBP/EP300 inhibitory protein 1 (CRI1), a gene specifically expressed in malignant pleural mesothelioma. Four tandem repeats of the CRI1 promoter (CRI1-138 4x) caused significantly high promoter activity in malignant pleural mesothelioma cells but little promoter activity in normal mesothelial cells and normal fibroblasts. The recombinant adenoviral vector expressing proapoptotic BH3-interacting death agonist or early region 1A driven by the CRI-138 4x promoter induced cell death in malignant mesothelioma cells but not in normal cells. Moreover, these viruses showed antitumor effects in a mesothelioma xenograft mouse model. Here, we describe a novel strategy to target malignant mesothelioma using the CRI-138 4x promoter system.
