The hypoxia-inducible transcription factor 1 alpha (HIF-1 alpha) is the regulated member of the transcription factor heterodimer HIF-1 alpha/beta. HIF-1 alpha binds to hypoxia-response elements (HREs) in the promoters of many genes involved in the adaptation to an environment of insufficient oxygen or hypoxia. Hypoxic tissue environments occur in vascular and pulmonary diseases as well as cancer, which illustrates the broad impact of gene regulation by HIF-1 alpha.
