Hypoxia-Inducible Factors (HIFs) and Phosphorylation: Impact on Stability, Localization, and Transactivity
The hypoxia-inducible factor α-subunits (HIFα) are key transcription factors in the mammalian response to oxygen deficiency. The HIFα regulation in response to hypoxia occurs primarily on the level of protein stability due to posttranslational hydroxylation and proteasomal degradation. However, HIF α-subunits also respond to various growth factors, hormones, or cytokines under normoxia indicati...
متن کاملRegulation of iron homeostasis by the hypoxia-inducible transcription factors (HIFs).
Iron is essential for many biological processes, including oxygen delivery, and its supply is tightly regulated. Hepcidin, a small peptide synthesized in the liver, is a key regulator of iron absorption and homeostasis in mammals. Hepcidin production is increased by iron overload and decreased by anemia and hypoxia; but the molecular mechanisms that govern the hepcidin response to these stimuli...

15 صفحه اولSnapShot: Hypoxia-Inducible Factors
Molecular oxygen (O2) is a key substrate for mitochondrial ATP production and numerous intracellular biochemical reactions. The maintenance of O2 homeostasis is therefore essential for the survival of most species. During O2 deprivation, mammalian cells rely on multiple adaptations mediated by the hypoxia-inducible factors (HIFs), mTOR, autophagy, and the ER stress response. This SnapShot will ...
متن کاملHypoxia and Hypoxia-Inducible Factors in Leukemias
Despite huge improvements in the treatment of leukemia, the percentage of patients suffering relapse still remains significant. Relapse most often results from a small number of leukemic stem cells (LSCs) within the bone marrow, which are able to self-renew, and therefore reestablish the full tumor. The marrow microenvironment contributes considerably in supporting the protection and developmen...
