In this paper, the relationship between cell survival fraction and telomerase activity was investigated with the human hepatocellular cells HL-7702 and carcinoma cells SMMC-7721 irradiated by X-rays. The colony formation assay and TRAP (Telomeric repeat amplification protocol) method were used to determine the cell survival fraction and telomerase activity respectively. To both of HL-7702 and SMMC-7721, the telomerase activity was increased in dose-dependent. However, at 1—3 Gy, the telomerase activity was lower than that of control in SMMC-7721, and it was a little higher than that of control when irradiated at 4 Gy. At 1—4 Gy, the variation trend of cell survive and that of telomerase activity were identical.
