Figure 3. miR-630 is the direct target of circRNA_100269. (A) Fluorescence intensity was significantly reduced in the miR-630 mimics and wild-type dual-luciferase reporter plasmid-transfected group in the two GC cell lines. (B) Fluorescence showed no significant change in the miR-630 mimics and mutant dual-luciferase reporter plasmid-transfected group in the two GC cell lines. Error bars represent mean of three separate determinations ± standard deviation (SD). Asterisk indicates statistically significant changes: * (P < 0.05), ** (P < 0.01).
