Transcription regulator protein BACH1 is a critical physiological repressor of heme oxygenase 1 (HMOX1). BACH1 binds to the multiple Maf recognition elements (MAREs) of HMOX1 enhancer MafK in vitro and represses its activity in vivo. BACH1 is inducible by hypoxia and IFN-gamma (Kitamuro et al, 2003; Sun et al, 2002).NFE2L2 (nuclear factor erythroid 2-related factor 2) is a transcription factor that activates transcription of a battery of cytoprotective genes by binding to the ARE (antioxidant response element). It is considered not only as a cytoprotective factor regulating the expression of genes coding for anti-oxidant, anti-inflammatory and detoxifying proteins, but it is also a powerful modulator of species longevity. HMOX1 is one of the genes whose expression it activates (Huang et al, 2000; Reichard et al, 2007).
