Nrf2 deficiency exacerbates ochratoxin A-induced toxicity in vitro and in vivo

Several mechanisms are postulated to be responsible for nephrotoxic and nephrocarcinogenic activities of mycotoxin and food contaminant, ochratoxin A (OTA). Although Nrf2 transcription factor was suggested to be involved in OTA-mediated renal injury, comprehensive study evaluating the effect of OTA toxicity in Nrf2 knock-out mice with special regard to sex-dependency has not been performed yet. Our results clearly show exacerbated OTA toxicity...
