Regulation and Destabilization of HIF-1α by ARD1-Mediated Acetylation
posttranslational phosphorylation of HIF-1␣ and promotes the transcriptional activity of HIF-1 (Richard et Hypoxia-inducible factor 1 (HIF-1) plays a central role al., 1999). According to a recent report, the hydroxylation in cellular adaptation to changes in oxygen availability. of asparagine (Asn803), located in the C-terminal trans-Recently, prolyl hydroxylation was identified as a key activ...
متن کاملOxygen-dependent hydroxylation by FIH regulates the TRPV3 ion channel.
Factor inhibiting HIF (FIH, also known as HIF1AN) is an oxygen-dependent asparaginyl hydroxylase that regulates the hypoxia-inducible factors (HIFs). Several proteins containing ankyrin repeat domains (ARDs) have been characterised as substrates of FIH, although there is little evidence for a functional consequence of hydroxylation on these substrates. This study demonstrates that the transient...
متن کاملThe role of reactive oxygen species in the stabilisation of hypoxia-inducible factor-1α (HIF-1α)
4 Abstract: At physiological oxygen concentrations ([O2]) hypoxia-inducible factor-1α (HIF-1α) is constantly hydroxylated and thus prepared for proteosomal degradation through the action of the prolyl hydroxylases (PHDs) (Jiang et al., 1996). In hypoxia, however, the oxygen-sensitive PHDs are inhibited and HIF-1α is stabilised. Other agents, including cytokines and growth factors have been show...
متن کاملOxygen versus Reactive Oxygen in the Regulation of HIF-1α: The Balance Tips
Hypoxia inducible factor (HIF) is known as the master regulator of the cellular response to hypoxia and is of pivotal importance during development as well as in human disease, particularly in cancer. It is composed of a constitutively expressed β subunit (HIF-1β) and an oxygen-regulated α subunit (HIF-1α and HIF-2α), whose stability is tightly controlled by a family of oxygen- and iron-depende...
متن کاملOxygen Sensing, Cardiac Ischemia, HIF-1α and Some Emerging Concepts
Oxygen plays a critical role in the perpetuation and propagation of almost all forms of life. The primary site of cellular oxygen consumption is the mitochondrial electron transport chain and in addition, oxygen is also used as a substrate for various enzymes involved in cellular homeostasis. Although our knowledge of the biochemistry and physiology of oxygen transport is century old, recent de...
