Following publication of the original article [1], the authors identified minor errors in Figs. 2, 3 and 4, specifically:

  • Figs. 2I, 2T, 4 H and 4 I: mismatched images were introduced in the colony formation assays

  • Fig. 3D: the statistical data of Fig. 3C was mistakenly duplicated in Fig. 3D

Hsa_circ_0005273 is highly expressed in BC and exerts oncogenic effects in BC cells. A-B Hsa_circ_0005273 was highly expressed in tumor tissues compared with adjacent normal tissues. C Expression of hsa_circ_0005273 in basal-like cohort, Her2-like cohort, luminal-A and luminal-B cohort, respectively. D Relative expression of hsa_circ_0005273 in BC cell lines. E Expression of hsa_circ_0005273 was confirmed by RT-qPCR in BC cells transfected with si-NC or si-circ_0005273. F-H Effect of si-circ_0005273 on proliferation in BC cells by MTT assay. I Effect of si-circ_0005273 on proliferation in BC cels by colony formation assay. J Effect of si-circ_0005273 on proliferation in BC cells by western blotting. K Cell migration assays were performed in MDA-MB-231 using transwell chambers. L Wound healing assays were performed in MDA-MB-231 treated with sicirc_0005273.

Hsa_circ_0005273 serves as a sponge for miR-200a-3p. A Venn diagram showing the potential target miRNAs of hsa_circ_0005273. B-D Expression of miRNAs in BC cells transfected with si-circ_0005273 or LV-circ_0005273. E RIP experiments were performed in HEK293T cells, and the co-precipitated RNA was subjected to RT-qPCR for hsa_circ_0005273 and miR-200a-3p. F MiR-200a-3p was pulled down and enriched with hsa_circ_0005273 specific probe and then detected by RT-qPCR. G Putative complementary sites within miR-200a-3p and hsa_circ_0005273 predicted by bioinformatics analysis (starbase). H Dual luciferase reporter assays demonstrated that miR-200a-3p is a direct target of hsa_circ_0005273. I Detection of colocalization of hsa_circ_0005273 and miR-200a-3p in cytoplasm by RNA FISH assay (magnification, × 400).

MiR-200a-3p is expressed at low levels and acts as a tumor suppressor in BC cells. A-B MiR-200a-3p had low expression in BC tissues compared with adjacent normal tissues. C Correlations between the expression of hsa_circ_0005273 and miR-200a-3p were found with Pearson’s correlation analysis in BC tissue samples (n = 120). D MiR-200a-3p had low expression in BC cell lines. E-G Effect of miR-200a-3p-mimics on proliferation in BC cells by MTT formation assay. H-I Effect of miR-200a-3p-inhibitor on proliferation in BC cells by colony formation assay. J Effect of miR-200a-3p-inhibitor on proliferation in BC cells by western blotting. K Wound healing assays were performed in MDA-MB-231 cell treated with miR-200a-3p-inhibitor. L Cell migration assays were performed in MDA-MB-231 cells using Transwell chambers. M-O Cell cycle assays were performed in BC cells treated with miR-200a-3p-inhibitor. *p < 0.05, **p < 0.01,*** p < 0.001,**** p < 0.0001
