WebIrradiation of normal eukaryotic cells results in delayed progression through the G1, S, and G2 phases of the cell cycle. The G1 arrest is regulated by the p53 tumor suppressor gene product. Irradiation results in increased expression of p53, which in turn induces a 21 kDa protein, WAF 1/Cip 1, that inhibits cyclin CDK kinases. WebRadiation effects on a cell are random. That is, the same type and amount of radiation could strike the same cell many times and have a different effect, including no effect, each time. However, in general, the more radiation that strikes a cell, the greater the chances of causing an effect.
