Mitochondrial iron overload: causes and consequences

Tracey A Rouault, Current Opinion in Genetics & Development, Volume 38, June 2016, Pages 31-37, ISSN 0959-437X, http://dx.doi.org/10.1016/j.gde.2016.02.004.

The mystery of mitochondrial iron overload diseases — how is mitochondrial iron homeostasis regulated? Despite the fact that much is now known about how mitochondrial Fe-S clusters are assembled and transferred, several major mysteries remain about how mitochondria regulate iron homeostasis in the mitochondrial matrix.The challenge ahead is to identify the full roster of transporters involved in mitochondrial iron homeostasis and to try to identify a regulatory ‘overlord’ that regulates a nuclear transcriptional response to perceived iron deficiency.
