The capacity of some linear and angular furocoumarins to induce DNA-protein cross-links by UVA (320-400 nm) irradiation has been evaluated in Chinese hamster ovary cells. Two linear furocoumarins, psoralen and 8-methoxypsoralen appeared to be capable of inducing DNA-protein cross-links to a noticeable extent. 4'-Methylangelicin and 4,4'-dimethylangelicin formed only reduced amounts of DNA-protein cross-links, while angelicin and 4,6,4'-trimethylangelicin seemed to be unable to induce significant levels of this lesion.

We studied the DNA replicon size in BALB/c and BALB/Mo mouse lymphocytes by the method of bromodeoxyuridine photolysis. After treatment of the BALB/Mo lymphocytes in vitro with mitomycin C, the average DNA replicon size appeared to be significantly smaller than that observed in BALB/c lymphocytes treated similarly. In these conditions an increased susceptibility to SCE induction in BALB/Mo lymphocytes had been observed.
