Transcriptional Regulation by Hypoxia-Inducible Factor 1 Molecular Mechanisms of Oxygen Homeostasis

Abstract excerpt

Human cells require O(2) for many metabolic processes, most notably oxidative phosphorylation, the major source of ATP generation, and hypoxia plays a significant pathophysiologic role in a variety of cardiovascular disorders. Hypoxia-inducible factor 1 (HIF-1) is a transcriptional activator of genes whose products, including erythropoietin, vascular endothelial growth factor, and glycolytic enzymes, are involved...
