| 摘 要： | 目的为成功建立放射抗拒性鼻咽癌细胞系亚株，并探讨鼻咽癌放射抗拒机理。方法采用类似临床放疗的照射模式反复照射从人鼻咽癌细胞系CNE-3中分离出具有放射抗拒性的新细胞系亚株。结果采用类似临床放疗的照射模式反复照射分离出具有放射抗拒性的新细胞系亚株CNE-3R，其在传代3个月后仍表现出较稳定的放射抗拒性，其SF2值均〉0．5。结论采用该研究方法能成功建立放射抗拒性鼻咽癌细胞系亚株，为研究鼻咽癌放射抗拒机理提供了必要的工具。 |

| Abstract: | Objective To establish radioresistant cell subline from a human nasopharyngeal carcinoma cell line CNE-3 and investigate the mechanism of radioresistanee. Methods Radioresistant cell subline were established from a human nasopharyngeal carcinoma cell line CNE-3 by repeating X-ray irradiation as radiotherapy. The radiosen- sitivity of this subline, together with its parent CNE-3 cell line, were measured. Results This subline, named CNE-3R could be subcultured steadily three months, and kept SF2 〉 0.5. Conclusion Radioresistant cell subline from a hu- man nasopharyngeal carcinoma cell line successfully was established by using the method of research, which providing the tools for the study of the mechanism of radioresistance. |
