When cells were cultured in the absence of IL-3, Hif-1 α mRNA decreased over time and growth factor-deprived cultures failed to increase Hif-1 α mRNA levels when exposed to 1.5% oxygen ( Fig. 2C ).

Studies have found that HIF-1α and HIF-2α expression is increased in some human cancers (2). HIF-1α has both pro- and anti-proliferative activities, whereas HIF-2α does not possess anti-proliferative activity (2). Therefore, HIF-2α likely plays an important role in tumorigenesis (2,3).
Web25 de nov. de 2024 · Hypoxia-inducible factor (HIF), an αβ dimer, is the master regulator of oxygen homeostasis with hundreds of hypoxia-inducible target genes. Three HIF isoforms differing in the oxygen-sensitive α subunit exist in vertebrates. While HIF-1 and HIF-2 are known transcription activators, HIF-3 has been considered a negative regulator of the …
