hsa-miR-9-5p promoted cell proliferation and inhibited cell apoptosis after irradiation (IR) in vitro (n = 5). (A) The cell proliferation was determined using CCK-8. Compared with Control group, the cell proliferation in hsa-miR-9-5p group was significantly decreased with IR. (B) The cell apoptosis was determined using flow cytometry. Cell apoptosis in hsa-miR-9-5p group with exposure to IR were significantly higher than those in the control groups. (C) The colony formation ability with exposure to IR was significantly decreased in hsa-miR-9-5p group as compared with the control groups (# p < 0.05 vs. miR-NC; * p < 0.05 and ** p < 0.01 vs. corresponding miR-NC+IR).
