Blockade of VEGFR-1 and VEGFR-2 Enhances Paclitaxel Sensitivity in Gastric Cancer Cells

Hwang JE, Lee JH, Park MR, Kim DE, Bae WK, Shim HJ, Cho SH, Chung IJ

PURPOSE: Hypoxia-inducible factor-1alpha (HIF-1alpha) increases transcription of the vascular endothelial growth factor (VEGF) gene. Inhibition of VEGF abolishes VEGF mediated induction of HIF-1alpha. Recent reports suggested that HIF-1alpha also mediated...
