UV sensitivity of XPA cells pretreated with siRNA against TLS polymerases. Cells were transfected with siRNA, and UV irradiated after 48 h at the indicated doses. Viability was determined 48 h after UV irradiation by measuring cellular ATP (A) or 12 days after UV irradiation by measuring colony forming ability (B). (C) XPA cells stably expressing CPD photolyase were UV irradiated at 3 Jm−2 and immediately illuminated with visible light to photoreactivate CPD lesions. Cell viability was determined as in A. See Materials and Methods for details.
