H19 targets miR-130a-3p. (A) Predicted binding sites of miR-130a-3p in H19 3ʹ-UTR. (B and C) Dual-luciferase reporter gene detection and RNA immunoprecipitation assay confirmed the relationship between H19 and miR-130a-3p. (D) MiR-130a-3p was downregulated in BC tissues compared to adjacent normal tissues. (E) MiR-130a-3p level was significantly decreased in BC cells compared to MCF-10A cells. (F and G) The miR-130a-3p mimic increased miR-130a-3p expression compared to negative controls (NC), while miR-130a-3p inhibitor decreased the expression of miR-130a-3p. (H) Negative correlation between H19 and miR-130a-3p expression in breast cancer tissues. **P < 0.01, compared to the NC group; ##P < 0.01, compared to the inhibitor group.
