Hif-1 and mechanisms of hypoxia sensing
WebFIH-1: a novel protein that interacts with HIF-1alpha and VHL to mediate repression of HIF-1 transcriptional activity. Genes Dev 15, 2675-2686. Maxwell, P.H., Pugh, C.W., and Ratcliffe, P.J. (1993). Inducible … WebUnder hypoxia, HIF-1α binds to aryl hydrocarbon receptor nuclear translocator (ARNT, also called HIF-1β) to activate expression of genes important for cell survival. Alternatively, HIF-1α can bind to the tumor suppressor p53 and promote p53-dependent apoptosis. Here we show that the opposite functions of HIF-1α are distinguished by its phosphorylation …

Webmechanisms underlying HIF oxygen sensing.43 The HIF/PHD oxygen-sensing pathway plays a central role in cellular adaptation to hypoxia, regulating biologic processes essential for cell survival. These include glycolysis, mito-chondrial metabolism, angiogenesis, immune responses, and erythropoiesis (Figure 1).10 HIF transcription factors, of Web7 de jul. de 2024 · The p53 and HIF-1α pathways are interlinked in response to hypoxia. Our model characterizes the sensing of hypoxia, activation of p53 and HIF-1α, and decision-making in cell fates (Fig. 1). We focused on the regulation of p53 stability and activity by HIF-1 under various hypoxic conditions. More details of the model are …
