Recent progress in the development of hypoxia-inducible factor 2α (HIF ...
2024年9月5日 · Hypoxia-inducible factor 2α (HIF-2α) is a critical transcription factor that regulates cellular responses under hypoxic conditions. In situations of insufficient oxygen supply or patients with Von Hippel–Lindau (VHL) mutations, HIF-2α accumulates and forms a heterodimeric complex with aryl hydrocarbon receptor nuclear translocator (ARNT ...
Hypoxia-Inducible Factor 2 Alpha (HIF2α) Inhibitors: Targeting ...
Activation of hypoxia-inducible factor subunit 2 alpha (HIF2α) is a frequent feature of cancers. Preclinical and clinical data suggest HIF2α dependence in several cancers with disruption of the HIF2 pathway integrity
Hypoxia-Inducible Factor 2 Alpha (HIF2α) Inhibitors: Targeting ...
2023年3月4日 · Here we briefly recapitulate the molecular rationale for HIF2α blockade in tumors and review available preclinical and clinical data, elaborating on mutations that might be particularly sensitive to this approach.
Biology of Hypoxia-Inducible Factor-2α in Development and …
HIF-2α transcriptional targets include genes involved in erythropoiesis, angiogenesis, metastasis, and proliferation. Therefore, HIF-2α contributes significantly to both normal physiology as well as tumorigenesis.
HIF-1 and HIF-2: working alone or together in hypoxia? - PMC
HIF-1α was the original HIF isoform identified by affinity purification using oligonucleotides from the EPO locus (1), while HIF-2α and HIF-3α were identified by homology searches or screens for interaction partners with HIF-1β.
FDA Approves Merck’s Hypoxia-Inducible Factor-2 Alpha (HIF …
2021年8月13日 · WELIREG is the first HIF-2α inhibitor therapy approved in the U.S. As an inhibitor of HIF-2α, WELIREG reduces transcription and expression of HIF-2α target genes associated with cellular proliferation, angiogenesis and tumor growth.
Novel cancer treatment paradigm targeting hypoxia-induced …
2023年7月18日 · HIF-1a and HIF-2a upstream and downstream pathways promoting cancer. HIF-1a expression varies with oxygen level in the cellular environment while HIF-2a is constitutively expressed and has some known oncogenic effects.
Hypoxia-inducible factor-2α is crucial for proper brain development
2020年11月5日 · The hypoxia-inducible factor as a transcription factor conducts several hundred target genes during brain development and maintains normal function of the adult brain by reacting to changes...
HIF-2α is indispensable for regulatory T cell function - PubMed
2020年10月6日 · We show crosstalk between HIF-2α and HIF-1α, and that HIF-2α represses HIF-1α expression. HIF-1α is upregulated in HIF-2α-KO Treg cells and further deletion of HIF-1α restores the inhibitory function of HIF-2α-KO Treg cells.
Hypoxia inducible factor (HIF-1a and HIF-2a) expression in early ...
2001年3月1日 · Hypoxia inducible factor 1a and 2a (HIF-1a and HIF-2a) are key proteins regulating cellular response to hypoxia. Because the efficacy of photodynamic therapy (PDT) is dependent on the presence of oxygen, the assessment of HIF-1a and HIF-2a expression may be of value in predicting clinical response t …
