الوصف: Colorectal cancer is one of the most common cancers. Survivin is strongly immunogenic in a fraction of colorectal cancer patients. The present study was designed to determine whether full-length mouse Survivin dominant-negative mutant SurvivinT34A has the antitumor activity in a murine colon carcinoma model. The complex of cationic liposome (DOTAP/Chol) to plasmid pORF9-mSurvivin T34A was administered intravenously in a mouse subcutaneous (S. C.) CT 26 tumor model. Apoptotic cells and anti-angiogenesis were evaluated by fluorescent in situ TUNEL assay and by immunohistochemistry with an antibody reactive to CD31, respectively. A 4 h 51Cr release assay was performed to determine Survivin-specific cytotoxicity. The adoptive transfer of CD8+ or CD4+ T-lymphocytes assay was to further explore the roles of immune cell subsets. We demonstrated the complex of cationic liposome (DOTAP/Chol) to plasmid pORF9--mSurvivin T34A when administered intravenously induced an efficient antitumor activity in a S. C. CT26 tumor model in mice. The main mechanism is involved in three aspects: triggering the apoptosis of tumor cells, inhibiting angiogenesis, and inducing Survivin-specific immune response. Our observations may have potential implications for the further exploration of the treatment of human colorectal cancer by intravenous delivery of dominant-negative mutant Survivin T34A.
