miR-613 was lowly expressed in NPC tissues and cell lines and was related to radiosensitivity. (a) miR-613 expression in adjacent normal tissues and tumor tissues of the 121 cases of NPC patients was detected using RT-qPCR; NP-69, NPC cell line C666-1, and the constructed radiation tolerant strain C666-1R were selected for the in vitro study. (b) Cell viability of NPC cells after radiation treatment was detected using the CCK-8 method. (c) Cell survival fraction was detected by colony formation assay. (d) miR-613 expression was detected using RT-qPCR. Three repeated tests were performed. Data were expressed as mean ± SD. T-test was used for comparisons between 2 groups in panels (a) and (c), repeated variance test was applied for comparisons between 2 groups in panel (b), and one-way-ANOVA was used for comparisons among multi-groups in panel (d), followed by Tukey's multiple comparisons test. ∗∗p < 0.01.
