APOBEC3B promotes DNA double-strand breaks in myeloma cells. (a) Fluorescence immunostaining of γ-H2AX in RPMI8226 and AMO1 cells transduced with either control or A3B shRNA lentivirus. The images were obtained by confocal fluorescence microscopy (magnification, 630x). (b) Statistical analysis of the number of γ-H2AX foci per cell in RPMI8226 and AMO1 cells based on the images in (a). Approximately 200 cells were evaluated for each sample. All P values were calculated using Student’s t test. (c) Immunoblot analysis of γ-H2AX in RPMI8226 cells transduced with either control or A3B shRNA lentivirus. (d) Bar graph of the γ-H2AX band intensities from (c) normalized by the α-tubulin band intensity.
