The HIF pathway as a therapeutic target.

Journal article

Hypoxia-inducible factor (HIF) is an alpha,beta-heterodimeric transcription factor that mediates cellular responses to low oxygen concentration via the transcriptional activation of specific genes involved in both tumorogenesis and angiogenesis. Manipulation of the HIF pathway has potential use for the treatment of ischemic disease and cancer. Unlike HIF-beta, which is constitutively expressed, the levels and activity of the HIF-alpha subunit are regulated by processes involving posttranslational hydroxylation, catalyzed by Fe(II)- and 2-oxoglutarate-dependent oxygenases. This review focuses on the HIF pathway as a therapeutic target.
