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
