Figure 7. Expression levels of miR-337-3p, miR-216a-5p and miR-151a-5p expressions in clinical samples and cell lines. (A–C) RT-PCR shows that the expression levels of miR-337-3p, miR-216a-5p were significantly higher in BC tissues, while the expression levels of miR-151a-5p were lower in BC tissues, compared with non-tumor tissues. (D–F) The expression levels of miR-337-3p and miR-151a-5p were increased in the bladder cancer cell lines, while the expression levels of miR-216a-5p was decreased, compared with non-tumorigenic bladder cell line. *p < 0.05, **p < 0.01, ***p < 0.001.
