Apoptosis is a kind of programmed cell death, that is, intrinsically programmed "cell suicide process". Mammalian thymic lymphocytes, thymocytes, show a typical apoptosis immediately after a low dose irradiation. Apoptosis appears also during radiotherapy of tumor, especially of thymoma. Tumor suppressor gene such as p53 and oncogene such as bcl-2 are found to be closely related to apoptotic processes in a cell. Possible mechanisms underlying interrelationship between expression of these genes, apoptosis and carcinogenesis were discussed.
