Subsequently to the publication of the above article, the authors have realized that Fig. 4 on p. 145 (showing the results from the colony formation assay) was published containing erroneous images in Fig. 4C. Essentially, incorrect images were selected to represent the negative control (NC) experiments owing to an altered shooting angle and incorrect naming of the files.
The corrected version of Fig. 4, now showing the correct data for the NC experiments in Fig. 4C, is shown on the next page. The authors confirm that the error made in the presentation of Fig. 4 did not adversely affect either the results or the conclusions reported in this paper, and they are grateful to the Editor of International Journal of Oncology for granting them this opportunity to publish a Corrigendum. They also apologise to the readership for any inconvenience caused.
Effects of HIF-1α knockdown on HLEC colony formation and migration. (A) Relative mRNA expression of HIF-1α and VEGFR-3 in HLECs transfected with and short interfering RNA targeting HIF-1α. (B) HIF-1α and VEGFR-3 protein expression, (C) colony formation and (D) wound-healing assays (magnification, ×100) for HIF-1α knockdown and NC groups. Experiments were repeated ≥3 times with similar results and data are presented as mean ± standard deviation. *P<0.05 and **P<0.01 vs. NC. HLEC, human lymphatic endothelial cell; HIF-1α, hypoxia-inducible factor-1α; VEGF, vascular endothelial growth factor; NC, negative control.
