The intense fluorescence of ATM protein was stro ng er in karyon of CNE1than that in CNE2.CONCLUSION:The expression levels of ATM protein differ in CNE1and CNE2.The variance may be a potential facto r,which links with their different radiosensitivity.

• 结论:ATM蛋白的表达在CNE1、CNE2中有差别,这种差别可能与它们所具有的不同放射敏感性有关。
