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 ...
Gregg L. Semenza and Peter J. Ratcliffe studied the EPO gene and its oxygen-dependent regulation. Along with William Kaelin Jr., they were awarded the 2019 Nobel Prize in Physiology or Medicine for their discovery of hypoxia-inducible factor (HIF), which regulates the EPO gene, as well as other genes, in response to hypoxia.

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.
Semenza identified the gene sequences that expressed hypoxia-inducible factors (HIF) proteins. Semenza's work showed that the HIF proteins consisted of two parts; HIF-1β, a stable base to most conditions, and HIF-1α that deteriorated when nominal oxygen levels were present.

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 ...
Fig. 1 Achieving maximum aerobic capacity. Blood doping is defined as the use of illicit products (e.g. erythropoietin (EPO), darbepoetin-alfa, hypoxia-inducible factor (HIF) stabilizers) and methods (e.g. increase aerobic capacity by maximizing the uptake of O 2) in order to enhance the O 2 transport of the body to the muscles.
Kaelin's research found that in VHL subjects, there are genes that express the formation of a protein critical in the EPO process, but which the mutation suppressed. Kaelin's work aligned with that of Peter J. Ratcliffe and Gregg Semenza who separately had identified a two-part protein, hypoxia-inducible factors (HIF) that was essential to EPO ...
