Transcription factor HIF1A mediates transcriptional responses to hypoxia for a large number of genes to control cellular oxygen supply and maintain cell viability during periods of low oxygen concentration. This series explores the molecular mechanisms by which cells and organisms respond to stress, focusing on the variations in metabolic response that allow some cells and organisms to deal with extreme stress, others to endure stress within ... 2015 May;1853(5):881-91. doi: 10.1016/j.bbamcr.2015.01.011.

When induced by hypoxia or chemical hypoxia mimetics, the HIF1A transcription factor decouples from the ubiquitin/proteosome pathway and accumulates in the nucleus to activate target genes (Panel A). Nature. Functional regulation of hypoxia inducible factor-1α by SET9 lysine methyltransferase. Oncoimmunology. IL-35-producing B cells are critical regulators of immunity during autoimmune and infectious diseases. [10][69][70][71][72][68] HIF1A expression may also regulate breast tumor progression. So what is a transcription factor, and why is HIF-1a so important? [75][76] In addition, high-grade glioblastoma multiform tumors with high VEGF expression pattern, similar to breast cancer with HIF1A overexpression, display significant signs of tumor neovascularization. Short tandem repeat near hypoxia response element (HRE) instead of HRE genetic variants in promoter calcitonin receptor-like receptor (CRLR) gene as risk factor in severe preeclampsia: a preliminary study.

A 96-well enzyme-linked immunosorbent assay (ELISA) replaces the cumbersome radioactive electrophoretic mobility shift assay (EMSA). eCollection 2021. Immunity. HIF-1 is a heterodimer consisting of HIF-1alpha, which is encoded by the HIF1A gene, complexed with HIF-1beta, which is encoded by the ARNT gene. A functional map of genomic HIF1α-DNA complexes in the eye lens revealed through multiomics analysis. Here, we show that hypoxia-inducible factor-1α (HIF-1α) contributes … HIF-1α expression in B cells regulates helper T cell polarization in vitro. doi: 10.1038/nature12979. Suggested minimal checklist for reporting will enable faster development of a complete catalog of HIF-1α-TGs, data sharing, bioinformatics analyses, and setting novel more targeted hypotheses. Diseases associated with HIF1A include Hypoxia and Retinal Ischemia.Among its related pathways are Adipogenesis and AGE/RAGE pathway.Gene Ontology (GO) annotations related to this gene include DNA-binding transcription factor activity and protein heterodimerization activity. 1h2k: FACTOR INHIBITING HIF-1 ALPHA IN COMPLEX WITH HIF-1 ALPHA FRAGMENT PEPTIDE, 1h2l: FACTOR INHIBITING HIF-1 ALPHA IN COMPLEX WITH HIF-1 ALPHA FRAGMENT PEPTIDE, 1h2m: FACTOR INHIBITING HIF-1 ALPHA IN COMPLEX WITH HIF-1 ALPHA FRAGMENT PEPTIDE, 1l3e: NMR Structures of the HIF-1alpha CTAD/p300 CH1 Complex, 1l8c: STRUCTURAL BASIS FOR HIF-1ALPHA/CBP RECOGNITION IN THE CELLULAR HYPOXIC RESPONSE, 1lqb: Crystal structure of a hydroxylated HIF-1 alpha peptide bound to the pVHL/elongin-C/elongin-B complex, GO:0001131, GO:0001151, GO:0001130, GO:0001204 DNA-binding transcription factor activity, GO:0001077, GO:0001212, GO:0001213, GO:0001211, GO:0001205 DNA-binding transcription activator activity, RNA polymerase II-specific, transcription factor activity, RNA polymerase II distal enhancer sequence-specific binding, GO:0001200, GO:0001133, GO:0001201 DNA-binding transcription factor activity, RNA polymerase II-specific, RNA polymerase II transcription regulatory region sequence-specific DNA binding, RNA polymerase II transcription regulator complex, negative regulation of neuron apoptotic process, regulation of transforming growth factor beta2 production, positive regulation of chemokine-mediated signaling pathway, positive regulation of insulin secretion involved in cellular response to glucose stimulus, positive regulation of hormone biosynthetic process, negative regulation of mesenchymal cell apoptotic process, positive regulation of neuroblast proliferation, regulation of transcription, DNA-templated, positive regulation of erythrocyte differentiation, vascular endothelial growth factor production, regulation of thymocyte apoptotic process, positive regulation of epithelial cell migration, negative regulation of thymocyte apoptotic process, positive regulation of transcription, DNA-templated, positive regulation of nitric-oxide synthase activity, regulation of transcription from RNA polymerase II promoter in response to hypoxia, negative regulation of oxidative stress-induced neuron intrinsic apoptotic signaling pathway, positive regulation of pri-miRNA transcription by RNA polymerase II, retina vasculature development in camera-type eye, positive regulation of chemokine production, GO:0048552 regulation of catalytic activity, positive regulation of autophagy of mitochondrion, epithelial cell differentiation involved in mammary gland alveolus development, positive regulation of vascular endothelial growth factor receptor signaling pathway, negative regulation of bone mineralization, positive regulation of endothelial cell proliferation, regulation of transcription from RNA polymerase II promoter in response to oxidative stress, hypoxia-inducible factor-1alpha signaling pathway, regulation of cell population proliferation, connective tissue replacement involved in inflammatory response wound healing, positive regulation of transcription from RNA polymerase II promoter in response to hypoxia, negative regulation of reactive oxygen species metabolic process, positive regulation of vascular endothelial growth factor production, positive regulation of glycolytic process, positive regulation of transcription by RNA polymerase II, positive regulation of blood vessel endothelial cell migration, regulation of transcription by RNA polymerase II, The Nobel Prize in Physiology or Medicine, GRCh38: Ensembl release 89: ENSG00000100644, GRCm38: Ensembl release 89: ENSMUSG00000021109, "Characterization of a subset of the basic-helix-loop-helix-PAS superfamily that interacts with components of the dioxin signaling pathway", "Entrez Gene: HIF1A hypoxia-inducible factor 1, alpha subunit (basic helix-loop-helix transcription factor)", "Hypoxia-inducible factor 1 is a basic-helix-loop-helix-PAS heterodimer regulated by cellular O2 tension", "Cellular and developmental control of O2 homeostasis by hypoxia-inducible factor 1 alpha", "Ras induction of superoxide activates ERK-dependent angiogenic transcription factor HIF-1alpha and VEGF-A expression in shock wave-stimulated osteoblasts", "Transactivation and inhibitory domains of hypoxia-inducible factor 1alpha.

[67] However, hypoxic conditions in tumor microenvironment especially, along with accumulation of genetic alternations often contribute to HIF1A overexpression. [26] In accordance with its dynamic biological role, HIF-1 responds to systemic oxygen levels by undergoing conformational changes, and associates with HRE regions of promoters of hypoxia-responsive genes to induce transcription. [23], The transcription factor HIF-1 plays an important role in cellular response to systemic oxygen levels in mammals. 2021 Feb 12;22(4):1857. doi: 10.3390/ijms22041857.

[46][47][48][49] Additionally the regenerative effect of HIF-1A modulation on aged skin cells was described[50][51] and a rejuvenating effect on aged facial skin was demonstrated in patients. Functions as a master transcriptional regulator of the adaptive response to hypoxia. 2007 Jun 8;316(5830):1497-502 In human HCC, ZFHX3 expression was up-regulated, and this up-regulation correlated with both HIF1A up-regulation and worse patient survival, confirming a functional association between ZFHX3 and HIF1A in human HCC. [72] Further, early-stage esophageal cancer patients with demonstrated overexpression of HIF1 and absence of BCL2 expression also failed photodynamic therapy.[80]. [29][35] The hydroxylated proline residue of HIF1A is then recognized and buried in the hydrophobic core of von Hippel-Lindau tumor suppressor protein (VHL), which itself is part of a ubiquitin ligase enzyme.
