KCNQ1OT1 knockdown inhibited proliferation, migration and invasion of NSCLC cells. A549 and H460 cells were transfected with si-KCNQ1OT1 or the control si-NC. a The expression of KCNQ1OT1 was detected by qRT-PCR in transfected cells. b Cell proliferation was evaluated using CCT-8 assay. c, d The migrated and invaded cells were measured by transwell assay. *P < 0.05
