Figure 1. The levels of miR-151a-3p were up-regulated in different NPC cell lines, especially in 5-8F cells.

(A) The levels of miR-151a-3p in NPC tissues were detected to make a comparison with the adjacent tissues using real-time quantification PCR (RT-qPCR). (B) The levels of miR-151a-3p in four types of NPC cell lines to screen an appropriate cell line for the following experiments. Each value represents mean ± SEM (n=3). U6 served as an internal control. **P<0.01 vs. Normal or NP69 groups.
