| 摘要 |
Methods are described for using an arginine depleting agent such as arginase and derivatives thereof, which reduce physiological arginine levels, as radioprotectants to protect normal mammalian cells from DNA damage caused by ionizing radiation. Treatment can result in the protection of normal tissues in cancer patients undergoing radiotherapy and in protection from the hazardous effects of exposure to radiological dispersal devices or occupational and environmental ionizing radiation.
