Résumé : Tumor hypoxia is a common feature of many cancers. A master regulator of hypoxic response is the transcription factor hypoxia-inducible factor-1 (HIF-1). It functions as a master regulator of oxygen and undergoes conformational changes in response to varying oxygen concentrations. In this paper, we review what has been described about HIF-1: its structure, its regulation and target genes, its role in cancer, and its implication for cancer therapy.
