Radiation-induced DNA double-strand breaks and the radiosensitivity of human cells: a closer look

N Foray, CF Arlett, EP Malaise - Biochimie, 1997 - Elsevier
A large number of reports suggest that DNA double-strand breaks (DSB) play a major role in
the radiation-induced killing of mammalian cells. However, the arguments supporting the
relationship between DSB and radiosensitivity are generally indirect. Furthermore, care must
be taken to allow for the possible impact of the techniques and of the experimental protocols
on the relationship between DSB and cell death. The recent data on DSB induction, repair
and misrepair in human cell lines and their correlation with intrinsic radiosensitivity are …
