DLL1 and non-small cell lung carcinoma: Down-regulation of LINC01783 suppressed proliferation of NCI-H460 and A-549 cells, but then overexpression of DLL-1 recovered the inhibitory effects induced by silenced LINC01783 on proliferative capacities of NSCLC cells according to the results of CCK-8 and EdU assays (Fig. 2d, e).
