To further understand the involvement of the miR-218-5p/YWHAZ/β-catenin pathway in the regulation of the metastatic potential of GC cells induced by SNHG12, Transwell assays were performed in MGC-803 and AGS cells transfected with pCDH-CMV-SNHG12 and/or miR-218-5p mimics. Here, SNHG12 is linked to gastric cancer.
