Abstract |
|---|
Hypoxia-Inducible Factor (HIF) is a transcription complex which responds to changes in oxygen, providing cells with a master regulator coordinating changes in gene transcription. HIF operates in all mammalian cell types, and is ancient in evolutionary terms - being conserved in C. elegans and D. melanogaster. This review summarises recent insights into the molecular events which link reduced oxygenation to HIF activation, and emerging insights into the extensive role of HIF in a broad range of physiological processes.
