Figure 7. KLF12 is a negative regulatory target of miR-188-5p. (A) The binding site between KLF12 and miR-188-5p. (B) The dual-luciferase assay results confirmed the existence of direct interaction between KLF12 and miR-188-5p (p < 0.05). (C) High expression of KLF12 in LUAD tissues was detected by western blot.
