Cobalt induces hypoxia-inducible factor-1 alpha (HIF-1 alpha) in HeLa cells by an iron-independent, but ROS-, PI-3K- and MAPK-dependent mechanism
(2006)
The iron-chelator desferrioxamine (DFO) and the transition metal cobalt induce hypoxia-inducible factor-1 alpha (HIF-1 alpha) in normoxia. DFO stabilizes HIF-1 alpha from proteolysis by inhibiting the activity of iron-dependent ...
Flavonoids induce HIF-1 alpha but impair its nuclear accumulation and activity
(2008)
Hypoxia-inducible factor-1 alpha (HIF-1 alpha) is the regulatory subunit of the transcription factor HIF-1, which is highly involved in the pathology of diseases associated with tissue hypoxia. In this study we investigated ...
The flavonoid quercetin induces hypoxia-inducible factor-1 alpha (HIF-1 alpha) and inhibits cell proliferation by depleting intracellular iron
(2007)
Quercetin, a flavonoid with anti- oxidant, metal chelating, kinase modulating and anti- proliferative properties, can induce hypoxia- inducible factor-1 alpha (HIF-1 alpha) in normoxia, but its mechanism of action has not ...
Bacterially produced human HIF-1 alpha is competent for heterodimerization and specific DNA-binding
(2005)
Hypoxia-inducible factor 1α (HIF- 1α) is the regulatory Subunit of HIF- 1. the transcriptional activator and key mediator of the cellular response to hypoxia. Regulation of HIF-1α Occurs at multiple levels ...
Transport of hypoxia-inducible factor HIF-1 alpha into the nucleus involves importins 4 and 7
(2009)
Hypoxia-inducible transcription factor 1 (HIF-1) mediates the cellular response to hypoxia. HIF-1 activity is controlled via the synthesis, degradation or intracellular localization of its alpha subunit. HIF-1 alpha contains ...
