HIF-3α Background Information Cell growth and viability is compromised by oxygen deprivation (hypoxia). Hypoxia-inducible factors, including HIF-1å, HIF-1∫ (also designated Arnt, EPAS-1 (also designated HIF-2å) and HIF-3å, induce glycolysis, erythropoiesis and angiogenesis in order to restore oxygen homeostasis. Hypoxia-inducible factors are members of the Per-Arnt-Sim (PAS) domain transcription factor family. In response to hypoxia, HIF-1å is upregulated and forms a heterodimer with Arnt 1 to form the HIF-1 complex. The HIF-1 complex recognizes and binds to the hypoxia responsive element (HRE) of hypoxia-inducible genes, thereby activating transcription. Hypoxia-inducible expression of some genes such as Glut-1, p53, p21 or Bcl-2, is HIF-1å dependent, whereas expression of others, such as p27, GADD 153 or HO-1, is HIF-1å independent. EPAS-1 and HIF-3å have also been shown to form heterodimeric complexes with Arnt 1 in response to hypoxia.
