Abstract: Hypoxia induces angiogenesis and glycolysis for cell growth and survival, and also leads to growth arrest and apoptosis. HIF‐1α, 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‐1α for hypoxia‐induced growth arrest and activation of p21cip1, a key cyclin‐dependent kinase inhibitor controlling cell cycle checkpoint, the mechanism underlying p21… Show more
