Web29 de abr. de 2024 · It is unclear how the HIF-2α–induced increase in iron-dependent ROS generation regulates distinct cell death pathways; this hence becomes an active area for future studies. HIF-2α inhibitors that are in clinical trials have shown promise, although acquired resistance to them is a major limitation for long-term efficacy (21, 22). Web3 de dez. de 2024 · Importantly, although HIF-1α and HIF-2α bind a common HRE sequence motif, they play distinct roles in regulating gene expression, which can reflect their tissue-specific expression, temporal pattern of induction, and interactions with other transcription factors. 53-56 In our studies, mice were subjected to phlebotomy, a …

Web(PHIs), HIF-2 stimulates erythropoietin (EPO) production in the kidneys and liver. This promotes erythropoiesis and leads to increased iron demand in the bone marrow. HIF coordinates erythropoisis with iron metabolism, as it regulates genes involved in iron uptake, release from internal stores, and transport (highlighted in red). WebHypoxia-inducible factor.
