Abstract: The present invention relates to a radiation inducible promoter, more particularly to a radiation inducible promoter including a base sequence represented by SEQ ID NO: 3 derived from Salmonella typhimurium, an expression vector including the promoter, a transformant including the expression vector, and a method for inhibiting and treating cancer using the transformant. Because the radiation inducible promoter of the present invention may control the amount of a target protein produced by radiation, problems such as cytotoxicity caused by overproduction of an anticancer agent in the cancer cell may be solved and the anticancer agent may be used as an effective treatment simultaneously with a radiation therapy due to production of the agent in a cancer cell.
