Relationship of hypoxia-inducible factor (HIF)-1alpha and HIF-2alpha expression to vascular endothelial growth factor induction and hypoxia survival in human breast cancer cell lines.

Abstract excerpt

Hypoxia-inducible factors (HIF-1 and HIF-2) are two closely related protein complexes that activate transcription of target genes in response to hypoxia. Expression of HIF-1alpha and HIF-2alpha and their effects on survival under hypoxia were studied in six human breast cancer cell lines. We also evaluated the basal and inducible expression of two hypoxically regulated genes, vascular endothelial growth factor...
