Hypoxia-inducible factor 1-alpha , also known as HIF-1-alpha , is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1 ) that is encoded by the HIF1A gene .[ 5] [ 6] [ 7] The Nobel Prize in Physiology or Medicine 2019 was awarded for the discovery of HIF.
HIF1A is a basic helix-loop-helix PAS domain containing protein , and is considered as the master transcriptional regulator of cellular and developmental response to hypoxia .[ 8] [ 9] The dysregulation and overexpression of HIF1A by either hypoxia or genetic alternations have been heavily implicated in cancer biology, as well as a number of other pathophysiologies, specifically in areas of vascularization and angiogenesis , energy metabolism , cell survival, and tumor invasion.[ 7] [ 10] The presence of HIF1A in a hypoxic environment is required to push forward normal placental development in early gestation.[ 11]
Two other alternative transcripts encoding different isoforms have been identified.[ 7]
