Historical Background

Nrf2 was found as a member of nuclear factor erythroid 2 (NF-E2) transcription factor family in 1994 (Moi et al. 1994). Nrf2 is a basic Leucine Zipper (bZIP) transcription factor that belongs to the Cap’n’Collar (CNC) family (p45-NFE2, Nrf1, Nrf2, and Nrf3) and is expressed ubiquitously in various tissues (Moi et al. 1994). Yamamoto and his colleagues showed that Nrf2 forms a heterodimer with small Mafs and induces phase-II detoxifying enzymes through antioxidant response elements (AREs) in the promoter regions of the target genes (Tong et al. 2006). A myriad of studies have identified Nrf2 as a sensor that acts against oxidative stress or electrophilic chemicals. In spite of the similarity in nucleotide sequences between Nrf2 and NF-E2, it was not involved in erythropoiesis and development in a murine model.

Oxidative stress is featured by high levels of reactive oxygen species (ROS), which exerts a harmful effect...
