Then, to understand the way and the mechanism of cell death. In this study, A375 cells were found to accumulate p53 protein and undergo a cell cycle arrest in the G2/M phase after exposure to gamma-radiation. This alteration disapperaed in a short time and got back to normal cell cycling soon when the exposure dosage were less than 10 Gy. However, the arrest on G2/M phase persisted longer and finally under went a programmed cell death through caspase cascade when exposed to more than 10 Gy. 若是10格雷以下的照射，则在短时间的修复后即会回到正常的细胞周期﹔若是10格雷以上的照射，则在G2/M细胞期停滞后，逐渐有部份细胞藉由蛋白质裂解酵素连续活化而走向细胞程式死亡﹔若是更高剂量伽玛射线的照射(60格雷﹑80格雷)虽然可提高细胞程式死亡的比例，但可能也因细胞受到瞬间的伤害过大，使得细胞膜失去维持完整的能力，所以有部份细胞在短时间内即因细胞膜破裂，导致细胞坏死的现象发生。 14. 14.
