Hypoxia and mitochondrial inhibitors regulate expression of glucose transporter-1 via distinct Cis-acting sequences.
Studies of gene regulation by oxygen have recently defined the existence of a widely operative system that responds to hypoxia but not mitochondrial inhibitors and involves the induction of a DNA-binding complex termed hypoxia-inducible factor 1. This system has been implicated in the regulation of erythropoietin, certain angiogenic growth factors, and particular glycolytic isoenzymes. The glucose transporter Glut-1 is induced by both hypoxia and mitochondrial inhibitors, implying the operati...Expand abstract
