circDTL was upregulated and acted as an oncogene in NSCLC. (A) Levels of circDTL in 84 pairs of NSCLC and adjacent tissues. (B) Levels of circDTL in normal cell line BEAS-2B and NSCLC cell lines. (C) NSCLC cells were transfected with shNC or shRNA against circDTL (sh#1, sh#2) for 24 h, levels of circDTL were measured. (D) NSCLC cells were transfected as indicated and cell viability was measured at different time points. (E) NSCLC cells were transfected as indicated, cell migration was assayed. (F) Cell invasion was measured. Data were presented as mean ± SD. Experiments were performed at least three times. ^∗P < 0.05; ^∗∗P < 0.01.
