FIGURE 1

The effect of the overexpression of the RPA1 gene on the resistance of HEK293T cells to ionizing radiation and the proliferation rate. (A,B) The levels of mRNA (qRT-PCR) and protein (western blotting) of RPA1 48 h after cotransfection of cells with the plasmids encoding the dCas9-VPR activator and guide RNAs (three biological replicates per group in each analysis). (C) The proportion of surviving CFU after exposure to γ-radiation at 3 Gy (12 replicates per group). (D) The average number of cells per coloniy (25 randomly selected colonies per group). *, differences with the TC group are significant at p < 0.05 (Student’s t-test).
