Figure 3. TRPM2-AS could sponge miR-138-5p. (A) ENCORI starBase predicted the binding site between TRPM2-AS and miR-138-5p. (B) The TRPM2-AS could sponge miR-138-5p, validated by luciferase assay. TRPM2-AS-wt, wild-type TRPM2-AS containing the binding site. TRPM2-AS-mut, mutant TRPM2-AS without the binding site. (C) RIP assay further proved the binding site between TRPM2-AS and miR-138-5p. (D) RT-qPCR analysis revealed that the miR-138-5p expression was downregulated in OvC tissues compared with contralateral normal fallopian tube tissues (cNor FT) and normal fallopian tube tissues from patients with benign gynecological tumor (Nor FT). (E) The expression of TRPM2-AS and miR-138-5p was negatively correlated. **P<0.001.
