LINC01123 and neoplasm: Similarly, the transwell assay (Fig. 3D, E; Supplementary Fig. S2E, K, L) revealed that inhibition of LINC01123 or B7–H3 or enhancement of miR-214-3p reduced tumor invasion and migration ability (P < 0.05), while the opposite was seen when LINC01123 was overexpressed or miR-214-3p was inhibited (P < 0.05).
