Hypoxia induces angiogenesis and glycolysis for cell growth and survival, and also leads to growth arrest and apoptosis. HIF-1alpha, a basic helix-loop-helix PAS transcription factor, acts as a master regulator of oxygen homeostasis by upregulating various genes under low oxygen tension. Although genetic studies have indicated the requirement of HIF-1alpha for hypoxia-induced growth arrest and activation of p21(cip1), a key cyclin-dependent kinase inhibitor controlling cell cycle checkpoint, the mechanism underlying p21(cip1) activation has been elusive.

Oxygen homeostasis is crucial for a myriad of developmental, physiological, and pathophysiological processes. Hypoxia-inducible factor 1alpha (HIF-1alpha) plays a pivotal role in response to hypoxia by transcriptionally activating target genes involving oxygen uptake, transport, delivery, and consumption. HIF-1alpha activity is regulated primarily through the ubiquitin-proteasome degradation pathway, which targets the oxygen-dependent degradation domain (ODD) of HIF-1alpha.
