Hif-2α抑制剂
WebThe EPAS1 gene, often known as HIF2A, provides instructions for making a protein called hypoxia-inducible factor 2-alpha (HIF-2α). This protein is one part (subunit) of a larger protein complex called HIF, which plays a critical role in the body's ability to adapt to changing oxygen levels. HIF controls several important genes involved in cell ... Web1 de dez. de 2003 · It is demonstrated that HIF-2α does regulate a variety of broadly expressed hypoxia-inducible genes, suggesting that its function is not restricted, as initially thought, to endothelial cell-specific gene expression. ABSTRACT Transcriptional responses to hypoxia are primarily mediated by hypoxia-inducible factor (HIF), a heterodimer of HIF …

WebEPAS1. Endothelial PAS domain-containing protein 1 ( EPAS1, also known as hypoxia-inducible factor-2alpha (HIF-2α)) is a protein that is encoded by the EPAS1 gene in mammals. It is a type of hypoxia-inducible factor, a group of transcription factors involved in the physiological response to oxygen concentration. Web16 de mar. de 2024 · Proteins known as hypoxia-inducible factors, including HIF-2α, can accumulate in patients when VHL, a tumor-suppressor protein, is inactivated. If not properly regulated, the accumulation of HIF-2α can stimulate several oncogenes associated with cellular proliferation, angiogenesis and tumor growth, leading to the growth of both …
