To elucidate the mechanism of the LINC01315/miR-211/DLG3 axis in regulating tumor growth in vivo, we constructed cell lines stably co-transfected with sh-NC and inhibitor NC, sh-LINC01315 and inhibitor NC, sh-LINC01315 and miR-211 inhibitor, sh-DLG3 and inhibitor NC, as well as sh-DLG3 and miR-211 inhibitor. This evidence concerns the gene LINC01315 and neoplasm.
