Regulation of intracellular iron levels in iron-acceptor and iron-donor cells

Abstract

In recent years many new genes and proteins were identified with crucial functions in iron metabolism. This gave an explosion of our knowledge and understanding of iron related disorders. Mutations have been found that are responsible for disturbances in iron transport, leading to either iron overload or iron deficiency. For experts in the field, these new findings clarify the sky and open new routes for exploring hitherto hidden fields of research. For the physician, however, iron metabolism may become even more complicated. In this review, we have tried to assemble all new iron related genes into the context of pathophysiology. Important results from animal experiments, mainly derived from knockout mouse models, are included in this review as they often explain the phenotype of human disease.
