title: Characterization of the sensitivity to various genotoxic agents of the UVU1-CHO cell line, a double mutant from UV complementation group 1.
abstract: The UVU1 CHO cell line, a double mutant of the excision repair complementation group 1 UV4 cell line was characterized by a higher UV sensitivity than its parent (Busch et al (1989) Mutagenesis 4, 349-354). We show here that this mutant is not affected in a UV mutagenic pathway. In addition, the UVU1 cell line is about two-fold more sensitive to N-methyl-N'-nitro-N-nitrosoguanidine treatment than its parent without being more sensitive to cross-linking agents or ionizing radiations.
