The UV-irradiated plasmid pBSCATSV, which could express chloramphenicol acetyltransferase (CAT) in the presence of SV40 early promoter, was transfected into RBCF-1 cells derived from the goldfish (Carassius auratus). The cells were incubated in the dark for 24 h and then the CAT activity was measured. CAT expression relative to non-irradiated control was calculated. The CAT expression of the exponentially growing cells transfected with UV-irradiated plasmid was enhanced by fluorescent light (FL) preillumination of the cells 8 h before transfection. The efficiency of photorepair (PR) measured by CAT expression was also enhanced by the same FL preillumination. This suggests that FL preillumination enhances both photorepair and dark repair of RBCF-1 cells for UV-damaged plasmid transfected into the cells. The enhancement of repair of UV damage by FL preillumination was also observed in survival assays. When the UV-irradiated pBSCATSV was transfected into growth-arrested cells in confluent culture, CAT expression was less sensitive to UV irradiation, and FL preillumination was much less effective in enhancing photorepair and dark repair.
