WebHypoxia-Inducible Factor-1 (HIF-1) has been largely studied for its role in cell survival in hypoxic conditions. The regulation of HIF-1 is a complex process and involves a number of molecules and pathways. WebBesides these protective responses, HIF-1 and/or hypoxia have also been shown to be either anti-apoptotic or pro-apoptotic, according to the cell type and experimental …

Regulation of Hypoxia‐Inducible Factor‐1a by Reactive Oxygen ...
Web1 de nov. de 2006 · The primary factor mediating this response is the hypoxia-inducible factor-1 (HIF-1), an oxygen-sensitive transcriptional activator. HIF-1 consists of a constitutively expressed subunit HIF-1β and an oxygen-regulated subunit HIF-1α (or its paralogs HIF-2α and HIF-3α). Hypoxia-inducible factor 1-alpha, also known as HIF-1-alpha, is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1) that is encoded by the HIF1A gene. The Nobel Prize in Physiology or Medicine 2024 was awarded for the discovery of HIF. HIF1A is a basic helix-loop-helix … Ver mais HIF1 is a heterodimeric basic helix-loop-helix structure that is composed of HIF1A, the alpha subunit (this protein), and the aryl hydrocarbon receptor nuclear translocator (Arnt), the beta subunit. HIF1A contains a … Ver mais The transcription factor HIF-1 plays an important role in cellular response to systemic oxygen levels in mammals. HIF1A activity is regulated by a host of post-translational modifications: hydroxylation, acetylation, and phosphorylation. … Ver mais HIF1A is overexpressed in many human cancers. HIF1A overexpression is heavily implicated in promoting tumor growth and metastasis through its role in initiating angiogenesis and regulating cellular metabolism to overcome hypoxia. Hypoxia promotes apoptosis … Ver mais • Hypoxia inducible factors Ver mais The human HIF1A gene encodes for the alpha subunit, HIF1A of the transcription factor hypoxia-inducible factor (HIF1). Its protein expression … Ver mais HIF1A abundance (and its subsequent activity) is regulated transcriptionally in an NF-κB-dependent manner. In addition, the coordinated activity of the prolyl hydroxylases (PHDs) maintain the appropriate balance of HIF1A protein in the post-translation … Ver mais HIF1A has been shown to interact with: • ARNTL, • ARNT, • CREBB, • EP300, Ver mais WebHypoxia-inducible factor 1 (HIF-1) is an oxygen-regulated transcriptional activator that plays essential roles in mammalian development, physiology and disease pathogenesis.
