Correction to: Metalloproteases meprin-ɑ (MEP1A) is a prognostic biomarker and promotes proliferation and invasion of colorectal cancer.

CORRECTION: After publication of the original article [1] the authors found that the figure contained an incorrect version of Fig. 3a. This does not affect the results and conclusions of the article.

MEP1A knock-down inhibits colorectal cancer cell migration and invasion. Scratch assays and matrigel invasion assays showed that MEP1A knock-down LoVo cells had less migration ability (a) and invasion ability (b) than control LoVo cells. The wound areas were measured 36 h post injury. The results represent mean ± SD of at least 12 wounds and were analyzed by the Student’s t-test (* p < 0.05)
