KCNQ1OT1 and gastric cancer: Therefore, in order to further explore whether KCNQ1OT1 bound to miR-556-3p and affected the growth and metastasis of GC cells, we predicted the binding sites of KCNQ1OT1 with miR-556-3p by LncBase database (Fig. 5B), and constructed a GC cell model overexpressing miR-556-3p (Fig. 5C).
