Reconstitution of human hypoxia inducible factor HIF-1 in yeast: A simple in vivo system to identify and characterize HIF-1 alpha effectors
(2006)
Hypoxia inducible factor I (HIF-1), the master regulator of hypoxia-activated genes, is involved in many diseases and is a valid drug target. In order to develop a simple and genetically tractable in vivo system for HIF-1 ...
Oxygen-dependent secretion of a bioactive hepcidin-GFP chimera
(2013)
Hepcidin, a hepatic hormone, regulates serum iron levels by controlling both intestinal iron absorption and iron release from macrophages. Although transcription of hepcidin is controlled by diverse stimuli, it remains ...
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 ...
Building arks for tRNA: Structure and function of the Arc1p family of non-catalytic tRNA-binding proteins
(2010)
Following the intricate architecture of the eukaryotic cell, protein synthesis involves formation of many macromolecular assemblies, some of which are composed by tRNA-aminoacylation enzymes. Protein-protein and protein-tRNA ...
The tRNA aminoacylation co-factor Arc1p is excluded from the nucleus by an Xpo1p-dependent mechanism
(2005)
Arc1p, a yeast tRNA-binding protein, forms a complex with the aminoacyl-tRNA synthetases, methionyl tRNA synthetase (MetRS) and glutamyl tRNA synthetase (GluRS). Although this complex localizes normally in the cytoplasm, ...
The dietary flavonoid kaempferol effectively inhibits HIF-1 activity and hepatoma cancer cell viability under hypoxic conditions
(2010)
Hepatocellular carcinoma (HCC) is characterized by high mortality rates and resistance to conventional treatment. HCC tumors usually develop local hypoxia, which stimulates proliferation of cancer cells and renders them ...
