生化／生理作用
Hypoxia-inducible factor-1 (HIF1) is a transcription factor found in mammalian cells cultured under reduced oxygen tension that plays an essential role in cellular and systemic homeostatic responses to hypoxia. HIF1 is a heterodimer composed of an alpha subunit and a beta subunit. The beta subunit has been identified as the aryl hydrocarbon receptor nuclear translocator (ARNT). This gene encodes the alpha subunit of HIF-1. HIF-1α contains two transactivation domains located between amino acids 531 and 826. Overexpression of a natural antisense transcript (aHIF) of this gene has been shown to be associated with nonpapillary renal carcinomas. Two alternative transcripts encoding different isoforms have been identified. Specific disruption of the HIF-1 pathway is important for exploring its role in tumor biology and developing more efficient weapons to treat cancer. HIF-1alpha is a master regulator of the hypoxic response, and its proangiogenic activities include, but are not limited to, regulation of vascular endothelial growth factor (VEGF). HIF-1alpha protein expression often seen in invasive breast cancer. Recent data demonstrates that HIF-1alpha knockdown reduces tumorigenicity of MCF-7 cells and suggest a promising combination of both anti-HIF-1 strategy and traditional chemotherapy to improve cancer treatment.

Hypoxia-inducible factor 1 (HIF-1) activates erythropoietin gene transcription in Hep3B cells subjected to hypoxia. HIF-1 activity is also induced by hypoxia in non-erythropoietin-producing cells, suggesting a more general regulatory role. We now report that RNAs encoding the glycolytic enzymes aldolase

Hypoxia promotes angiogenesis by modulating the transcriptional regulator hypoxia-inducible factor 1alpha (HIF-1alpha). HIF-1alpha is a master regulator of the hypoxic response, and its proangiogenic activities include, but are not limited to, regulation of vascular endothelial growth factor (VEGF). The remodeling

Hypoxia inducible factor-1 (HIF-1) is an important transcription factor that stimulates tumor growth and metastases via several pathways. Activation of HIF-1 depends on the presence of its alpha-subunit. Hypoxia increases HIF-1alpha levels by inhibiting prolyl-hydroxylase--mediated hydroxylation and thereby preventing proteosome
