WebSince PHD activity is dependent on oxygen and ferrous iron, HIF-1 mediates not only oxygen- but also iron-regulated transcriptional gene expression. Here we show that copper (CuCl(2)) stabilizes nuclear HIF-1alpha under normoxic conditions, resulting in hypoxia-response element (HRE)-dependent reporter gene expression.

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).
