Human tumor cell lines of SMMC-7721 (liver cancer), hepG2 (liver cancer), HO-8910 (ovary cancer), and Hela (cervix cancer) were irradiated to 3Gy by ,60,Co γ rays and different cell cycle responses were found. The results showed that the SMMC-7721, hepG2 and HO-8910 cells displayed G,2,/M phase arrest and S phase temporally delayed after the irradiation. The Hela cells had an increased number of cells in both G,2,/M and S phase, which indicated that the G,2,/M and S checkpoints were both activated.
