BACKGROUND & OBJECTIVE: It is an effective way to induce radio-tolerant gene into hematopoietic cells in bone marrow for overcoming the suppression of radiotherapy on hematopoietic system. However, this also increases the radiation tolerance of tumor cells. This study was designed to investigate a method to specifically protect bone marrow cell from being damaged by radiation, along without increasing resistance of tumor cell to radiation. METHODS: The retrovirus vector of manganese superoxide dismutase (MnSOD) gene regulated by aminopeptidase N (APN) bone marrow-specific gene promoter was constructed and induced into myeloblastic KG1a and cancer cell BEL7402...
