Although the vast majority of DNA damage induced by radiation exposure disappears
rapidly, some lesions remain in the cell nucleus in very small quantities for
days to months. These lesions may cause a considerable threat to an organism and
include certain types of DNA double-strand breaks (DSBs) called 'unrepairable
DSBs'. Unrepairable DSBs are thought to cause persistent malfunctioning of cells
and tissues or cause late effects of radiation, especially the induction of
delayed cell death, mutation, senescence, or carcinogenesis. Moreover, the
measurement of unrepairable DSBs could potentially be used for retrospective
biodosimetry or for identifying individuals at greater risk for developing the
adverse effects associated with radiotherapy or chemotherapy. This review
summarizes the concept of unrepairable DSBs in the context of persistent repair
foci formed at DSBs.
