To mitigate iron toxicity from overaccumulation, cells and organs must carefully coordinate the regulation of iron. This can occur at the level of transcription, translation, or posttranslation of functional proteins [27]. The regulation of iron homeostasis is centered on the control of iron circulation and involves
