(C) PARP inhibitor treatment (olaparib: 1 µM, 1 hour) or lack of PARP1 suppresses the relocation of the GRFs of Neil3 to the DNA lesions. The laser stripe is indicated with yellow arrowheads. The relocation kinetics is shown in the right panel. Data represents mean ± SD from three biologically independent experiments (right panel). At least 20 cells were included in each experiment.
