Retraction: Differential Effects of VEGFR-1 and VEGFR-2 Inhibition on Tumor Metastases Based on Host Organ Environment

This article (1) has been retracted at the request of the editors. An internal review by the editors found that the same image was used to represent Total VEGFR-2 in lanes 1–6 and in lanes 7–12 in Fig. 2A, and the same image was used to represent VEGFR-1 in lane 1 of Supplementary Figs. S2B and S4A. In addition, there appears to be splicing in the image of the Phospho-VEGFR-1 Western blot in Fig. 2A between the Lung EC and Liver EC samples and in the image of β-actin in Supplementary Fig. S4A between the Normal lung and Lung metastases samples. These splicing alterations were noted when applying adaptive histogram equalization to the figure using image analysis software.
