| Research Abstract |
We generated disease models for neurodegenerative disorders by deleting selenoproteins, a major member of antioxidant enzymes. We have found that transcriptional factor Nrf2 activate in the selenoprotein-deficient neuronal tissue. In the absence of Nrf2, selenoprotein deficiency in neuronal tissue cause severe degenerative phenotype. These results reveal that selenoproteins are essential for maintaining homeostasis of neuronal tissue, and that Nrf2 has cytoprotective role against loss of selenorpoteins.
