Hif - 1α
WebHIF1 regulates the transcription of a broad range of genes that facilitate responses to the hypoxic environment, including genes regulating angiogenesis, erythropoiesis, cell cycle, metabolism, and apoptosis. The widely expressed HIF-1α is typically degraded rapidly in normoxic cells by the ubiquitin/proteasomal pathway. WebM1/M2 macrophage polarization plays a pivotal role in the development of acute lung injury (ALI). The hypoxia-inducible factor-1α/pyruvate kinase M2 (HIF-1α/PKM2) axis, which functions upstream of macrophage polarization, has been implicated in this process. The function of HIF-1α is known to be tig …

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 level can be measured by antibodies … Ver mais HIF1A abundance (and its subsequent activity) is regulated transcriptionally in an NF-κB-dependent manner. In addition, the coordinated activity … Ver mais HIF1A has been shown to interact with: • ARNTL, • ARNT, • CREBB, • EP300, • HIF1AN, Ver mais WebUnder hypoxic conditions, Hif-1 alpha translocates to the cell nucleus and associates with Hif-1 beta. This complex then binds to the HRE region of the DNA resulting in the …
Web16 de mai. de 2014 · HIF-1α has been carefully studied in the context of severe hypoxic stresses (<1% O 2 ), but it is also known to be present at oxygen tensions commonly found in normal tissues in vivo (∼1–13% O 2 ), albeit at much lower levels.
