The induction of vascular endothelial growth factor (VEGF) is an essential feature of tumor angiogenesis, and the hypoxia-inducible factor-1 (HIF-1) transcription factor is known to be a key mediator of this process. In colon cancer, the frequently mutated K-ras oncogene also can regulate VEGF expression, but the role that …

WebActivation of HIF-1α induces the gene expression of MRP in colon cancer cells. CoCl 2 is a common reagent used in vitro to mimic hypoxia-induced cell response by stabilizing HIF-1α through inhibition of PHDs and occupying the VHL-binding domain of HIF-1α. 16 CoCl 2 dose-dependently increased the protein expression of HIF-1α, MRP, and MDR1 ...
