After publication of this article [1], it came to our attention that there was an error in Fig. 4b, c. In Fig.4b, the migration images of vector groups were incorrect based on this error, the authors re-constructed the migration experiments of Fig. 4b, and the consistent results were obtained. In Fig. 4c, the tube formation image of the Z2P-UTR-siRNA&Z1-UTR group (MCF-7) of Fig. 7d was accidentally misused in control group (MCF-7) and vector group (MCF-7) of Fig. 4c. The corrected Fig. 4 is provided below. This error did not impact the conclusions of the article. The authors apologize for this error.

Z1-UTR could promote tumor-induced HUVEC cells proliferation, migration, and tube formation. a HUVECs were plated in 96-well plates, and then treated with CM as in the presently described method. Cell proliferation was measured by MTT assay. b HUVEC migration assays were performed through co-culturing transfected cells with HUVECs in 24-well plates with transwell chambers, and cell migration was measured at 18 h in a Transwell assay in a blinded manner. c Tube formation assays. Cells were seeded on Matrigelcoated wells in the presence of different CM, as indicated, and incubated for 18 h to form a capillary network. The total number of branched tubes was then counted. Values are mean ± SD. **P < 0.01 (n = 3, Student’s t test)
