Following publication of the original article [1], errors were found in Figs. 6 and 8. The band of β-actin in Fig. 6B (Basal) and the band of CD31 in Fig. 8F were mistakenly uploaded.

The corrected figures are provided below:

Effect of Andro on VEGF-induced angiogenesis. a HUVECs were exposed to Andro at the indicated doses, and viability was measured by CCK-8 assay. Data were represented as percentage of vehicle-treated control. b The expression level of COX-2 protein was analyzed by Western blot HUVECs treated with the indicated doses of Andro for 48 h, with or without VEGF induction. c-d Effects of Andro on tube formation on Matrigel c at 6 h (Original magnifcation, 50 ×), and sprouting from modifed human endothelial cell spheroids d at 24 h (Original magnifcation, 200 ×). Experiments were performed with or without VEGF and indicated Andro doses. (##p < 0.01, VEGF-treated group vs. Solvent; *P < 0.05, **P < 0.01, Andro treatment vs vehicle control groups)

Effect of Andro on tumor growth and tumor angiogenesis in a breast cancer mouse model. An orthotopic mouse model of human breast cancer MDA-MB-231 cells was used to evaluate the anti-tumor effect of Andro. The tumor pictures (a), tumor volumes (b) and total weights (c) were measured. d The expressions of COX-2 and CD31 in tumor samples were analyzed by immunohistochemistry and cofocol immunofluorescence, respectively. e The quantitative analysis of relative COX-2 expression and microvessel number were also performed. f The expression of COX-2 and CD31 proteins in tumor tissues was analyzed by Western blot. Data were represented as the mean ± S.D. (*P < 0.05, **P < 0.01, Andro treatment vs vehicle control groups, N = 5 mice/group. Magnification, 200 ×)

The corrections do not affect the overall result, discussion, or conclusion of the article.
