We find that multiple cellular pathways are commonly affected by the loss of frataxin in CNS and peripheral nervous system neurons and these changes are partially restored by HDACi treatment.

Emerging Regulatory Role of Nrf2 in Iron, Heme, and Hemoglobin Metabolism in Physiology and Disease.

Kasai Shuya, Mimura Junsei, Ozaki Taku, Itoh Ken. Frontiers in Veterinary Science 5,242 2018 DOI=10.3389/fvets.2018.00242

In this review article, we describe and discuss the roles of Nrf2 in various iron-mediated bioreactions and its possible coevolution with iron and oxygen. Nrf2 regulates a wide range of cytoprotective responses and protects cells against various diseases and toxicities. In this review, we will focus on the Nrf2-mediated cytoprotective response achieved by iron regulation and detoxification.
