KCTD21 and non-small cell lung carcinoma: The results showed that more NSCLC cells migrated into the lung tissues of lv-KCTD21-AS1-treated groups compared with the control, whereas siRNA-KCTD21-AS1 and miR-519d-5p treatment inhibited the migration of NSCLC cells into the lung tissue (Fig. 5a, b; Supplementary Fig. 9a).
