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 Web13 de abr. de 2024 · Furthermore, chromatin immunoprecipitation (ChIP) analysis and luciferase reporter assays revealed that hypoxia-inducible factor 1α (HIF-1α) specifically …

WebHypoxia-inducible factor 1-α (HIF-1α) and MYC are transcription factors that induce the expression of genes essential for cancer progression. Here, we report that HIF-1α and MYC are both indirectly targetable through inhibition of ABL kinases. 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. inappropriate quote of the day
ASAP3 is a downstream target of HIF-1α and is critical for progr
Web12 de jun. de 2024 · Hypoxia inducible factor-1α (HIF-1α) up-regulates the expression of programmed death ligand-1 (PD-L1) in some extracranial malignancies. However, whether it could increase PD-L1 expression in intracranial tumor is still unknown. Here, we explored the relationship between HIF-1α and PD-L1 expression in glioma, and investigated their … WebHIF-1α regulates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. Web29 de fev. de 2004 · Hypoxia-inducible factor (HIF-1) is an oxygen-dependent transcriptional activator, which plays crucial roles in the angiogenesis of tumors and mammalian … in a virtual meeting
