miR-100 increased γ-H2AX foci caused by X-ray irradiation and retarded DNA double strand breaks repair. A. Representative images of γ-H2AX foci for miR-100 mimics, miR-100 negative control, and non-transfected treated groups exposed to 4-Gy X-ray irradiation at different time points. B. Representative images of γ-H2AX foci in different groups of cells after 4-Gy X-ray irradiation. CCL-244 cells were stained for γ-H2AX at the indicated times and the mean number of γ-H2AX foci per cell (foci/cell) were then counted (**P < 0.01).
