Research Abstract |
Cellular response by low dose irradiation was calculated from response by high dose irradiation. Recently hyper-radiosensitivity response, that did not fitted to data calculated from response by high dose irradiation, was discovered. It was considered that hyper-radiosensitivity was due to bystander effect or biological dysfunction, however, it was not elucidated in detail. In this study, it was elucidated that radiation-induced membrane resoponse was trigger of hyper-radiosensitivity, signal molecular mediated by membrane rasponse was extracellularly transmitted and dysfunction of DNA repair mediated by this signal molecular induced cell death.
