Strain development Developed by Masayuki Yamamoto, Institute of Basic Medical Sciences and Center for Tsukuba Advanced Research Alliance, University of Tsukuba in 1996. The targeting vector containing lacZ-neo cassette was transferred into E14 ES cells to replace the 1.2 kb segment containing the rest of the exon 5 coding sequence of the Nrf2 gene.  
Strain description Nrf2 (Nfe2l2) Knockout mice. This strain is a useful model for the in vivo analysis of chemical carcinogenesis and resistance to anti-cancer drugs. A phenolic antioxidant significantly induced the expression of phase II enzymes such as glutathione S-transferase and NAD(P)H: quinone oxidoreductase in normal mice. However, in the homozygous Nrf2 deficient mice the induction of the phase II enzymes by a phenolic antioxidant was largely eliminated in the liver and intestine. Since Nrf2 is constantly degraded by proteasome under normal condition, it is hardly to detect Nrf2 protein in the absence of stimuli. Electrophilic chemicals, such as DEM (diethyl maleate) and tBHQ (tert-buthyl hydroquinone), are generally used to stabilize Nrf2. Or proteasomal inhibitors, such as MG132, are also effective increasing the protein amount of Nrf2. C57BL/6 background (RBRC01390), BALB/c background (RBRC02190), A/J background (RBRC02414), ICR mixed background (RBRC00984). Homozygous mutant mice are viable and fertile, but show lower reproductive performance.
