ρ0206_B cells were infected with control, ATAD3B-Flag or ATAD3B (mLIR)-Flag. After two weeks, total DNA from cells was isolated and used to calculate the mutation rate of 3243A>G by quantitative real-time PCR using the TaqMan Probe. Data are presented as mean ± SD (n =3 independent experiments), statistical significance was assessed by a one-way ANOVA, N.S., not significant, *p < 0.05.
