[Inducible repair of DNA single-strand breaks in gamma-irradiated Chinese hamster cells].
Preirradiation of Chinese hamster cells with low-level UV-light does not influence the efficiency of repair of gamma-radiation-induced DNA single-strand breaks. With fractionated gamma-irradiation, cycloheximide delivered during the interval between the two fractions reduces the number of DNA breaks (compared to that in cells affected by the same nonfractionated dose). The data obtained indicate the presence of an inducible component of repair of DNA single-strand breaks in gamma-irradiated Chinese hamster cells.
