Oncogenes and radiation carcinogenesis.
Current research indicates a role for several oncogenes in radiation-induced carcinogenesis in vivo and cell transformation in vitro. Certain oncogenes are probably also involved in some cases of human cancer caused by exposure to nonionizing radiation and may play a mechanistic role in the phenomenon of radioresistance seen in later stages of tumor progression. The mechanisms of oncogene activ...
متن کاملRisk of Radiation Carcinogenesis
Occupational radiation exposure from the space environment may increase cancer morbidity or mortality risk in astronauts. This risk may be influenced by other space fl ight factors including microgravity and e nvironmental contaminants. A Mars mission will not be fe asible unless improved shielding is developed or transit time is decreased. – Human Research Program Requirements Document, HRP-47...
متن کاملIonizing Radiation Carcinogenesis
1.1 Ionizing radiation Human exposure to ionizing radiation is a natural part of life on earth. These exposures occur every day from radiation associated with naturally occurring radionuclides in soil, air, and food, and also from cosmic rays. In addition, many people are exposed to dental and medical diagnostic procedures and therapy involving: x rays, gamma rays, charged particles, radionucli...

متن کاملRadiation-induced Non-targeted Effect and Carcinogenesis; Implications in Clinical Radiotherapy
Bystander or non-targeted effect is known to be an interesting phenomenon in radiobiology. The genetic consequences of bystander effect on non-irradiated cells have shown that this phenomenon can be considered as one of the most important factors involved in secondary cancer after exposure to ionizing radiation. Every year, millions of people around the world undergo radiotherapy in order to cu...
