Hypoxia-inducible factors (HIFs) are transcription factors that respond to decreases in available oxygen in the cellular environment, or hypoxia. [1] [2] They also respond to instances of pseudohypoxia, such as thiamine deficiency. [3] [4] Both hypoxia and pseudohypoxia leads to impairment of adenosine triphosphate (ATP) production by the ...

Hypoxia-inducible factor 1-alpha, also known as HIF-1-alpha, is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 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.
Hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) are a novel class of oral medications developed for the treatment of anemia in chronic kidney disease (CKD). These drugs work by inhibiting hypoxia-inducible factor-proline dioxygenase (HIF prolyl-hydroxylase), which are responsible for the degradation of hypoxia-inducible factor ...
From 2000 to 2006, EPO tests at the Olympics were conducted on both blood and urine. [30] [31] However, several compounds have been identified that can be taken orally to stimulate endogenous EPO production. Most of the compounds stabilize the hypoxia-inducible transcription factors which activate the EPO gene. The compounds include oxo ...
Endothelial PAS domain-containing protein 1 (EPAS1, also known as hypoxia-inducible factor-2alpha (HIF-2α)) is a protein that is encoded by the EPAS1 gene in mammals. It is a type of hypoxia-inducible factor, a group of transcription factors involved in the physiological response to oxygen concentration.
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [1] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [2]
Hypoxia-inducible factor (HIF) is an evolutionarily conserved transcription factor [7] that allows the cell to respond physiologically to low concentrations of oxygen. [8] A class of prolyl hydroxylases which act specifically on HIF has been identified; [ 9 ] hydroxylation of HIF allows the protein to be targeted for degradation. [ 9 ]
