MiR-17-5p decreased expression in radioresistant NPCs and elevated the proliferation of NPC cells after irradiation. A-C. miR-17, miR-18a, and miR-20a expression in radiosensitive and radioresistant NPCs, and each group contained 15 samples. D, E. NPC cells were transfected with miR-17-5p mimics or a negative control (NC) and treated with different does of irradiation. The cell cycle was measured and the percentage of each phase was calculated (n = 5). F, G. NPC cells transfected with miR-17-5p mimics or a negative control were treated with different doses of radiation. The colonies numbers were counted and analyzed after 3 weeks (n = 5). H. The growth curve of NPC cells transfected miR-17-5p followed by 10 Gy irradiation was determined by MTT assay in the initial 5 days (n = 5). *: P < 0.05, **: P < 0.01.
