Following publication of the original article [1], the authors identified some minor errors in image-typesetting in Fig. 4; specifically, the transwell invasion assay of HCT116 cells with circLONP2-overexpression shown in Fig. 4b.

circLONP2 is essential for CRC metastasis. a, b Overexpression of circLONP2 significantly enhanced the migration and invasion ability of CRC cells. c, d Knockdown of circLONP2 by ASO significantly suppressed the migration and invasion ability of CRC cells. e, f In vivo tail vein injection model confirmed that overexpression or knockdown of circLONP2 could significantly promote or attenuate CRC cells metastasize to lung, respectively. All detection of circLONP2 by RT-qPCR was normalized to GAPDH. All experiments were repeated for three times, data were shown as mean±SD, * P<0.05, ** P<0.01, *** P<0.001, **** P<0.0001 in Mann-Whitney U test (a, c, e, f), or independent Student’s t test (b, d)

The corrected figure is given below. The corrections do not have any effect on the final conclusions of the paper.
