The authors found an error in the Figs. 3c–d and 4c–d of the original publication [1]. During the combination of the images of Figs. 3 and 4, the migration and invasion images were mixed up. The incorrect and correct figures are published in this correction article. The original article has been updated.

Fig. 3

Enhanced metastasis of CRC cells with overexpressed TUG1. a Representative image and number statistics for colony formation in SW480^pcDNA and SW480^pcDNA-TUG1 cells. b Wound-healing assay for motility of SW480^pcDNA and SW480^pcDNA-TUG1 cells. Representative pictures of one field at the beginning (t = 0) (left panel) and at the end of the recording (t = 12 h) (right panel) in each condition. c Representative images of transwell migrated cells and d invaded cells in stably transfected SW480^pcDNA and SW480^pcDNA-TUG1 cells and average number of migrated cells and invaded cells are shown in the right of (c) and (d). Values represent mean ± SD. *P < 0.05 compared with pcDNA

Silenced TUG1 inhibited metastasis of CRC cells. a Representative image and number statistics for colony formation in LOVO^si-control and LOVO^si-TUG1 cells. b Wound-healing assay for motility of LOVO^si-control and LOVO^si-TUG1 cells. Representative pictures of one field at the beginning (t = 0) (left panel) and at the end (t = 12 h) (right panel) of the recording in each condition are shown. c Representative images of transwell migrated cells, and d invaded cells in stably transfected LOVO^si-control and LOVO^si-TUG1 cells and the average number of migrated cells and invaded cells are shown in the right of (c) and (d). Values represent mean ± SD. *P < 0.05 compared with si-control
