Role of the HIF oxygen sensing pathway in cell defense and proliferation through the control of amino acid metabolism

Cell responses to reduced oxygen supply (hypoxia) are largely mediated by hypoxia-inducible transcription factors (HIFs). The pathophysiological role of the HIF pathway is driven by its ability to potentiate key biological processes as part of the adaptation to hypoxia, such as erythropoiesis and angiogenesis. Moreover, the role of HIF signaling in the reprogramming of cell metabolism is also critical to understand the role of these...
