Abstract

Elucidation of the molecular mechanism(s) of cell death induced by ionizing radiation is a main topic in the field of radiation biology. Radiation-induced cell death has been classified as interphase death estimated by vital cell counting and reproductive death estimated by colony forming assay. Recently, many modes of cell death, such as apoptosis, autophagy, mitotic catastrophe, senescence-like cell death, etc. have been reported. In this review, (1) classification of modes of cell death induced by ionizing radiation, (2) radiation-induced apoptosis and its molecular mechanism, (3) significance of radiation-induced cell death are summarized. Discussion on radiation-induced cell death will also focus on radiation-induced normal tissue damage and strategies in radiation cancer
