Hif-1 and mechanisms of hypoxia sensing

WebThe mechanisms of oxygen sensing and the mechanisms by which hypoxia induces stabilization of the HIF-1α protein are currently unknown. The finding by several investigators of an inhibitory effect of H 2 O 2 on HIF-1 formation and Epo gene expression suggested that redox changes are likely to be involved in oxygen sensing and/or signal … WebHypoxia induces the stabilization and transcriptional activation of the hypoxia-inducible factor 1α (HIF-1α) protein, the regulatory member of the HIF-1 complex. The molecular mechanisms that are responsible for oxygen sensing and the downstream pathways utilized by the hypoxic signal are still poorly understood. One hypothesis for oxygen …
