Disease relevance of Prdx3

  • Furthermore, in vivo adenoviral gene transfer of Prx-3 completely inhibited protein nitration and markedly reduced gliosis, a post-neuronal cell death event [1].
  • Since mitochondrial Prx-3 seems to be neuroprotective against oxidative insults, our findings suggest that Prx-3 up-regulation might be a useful novel approach for the management of neurodegenerative diseases [1].

High impact information on Prdx3

  • In the present study, we focused on a mitochondrial antioxidant protein, peroxiredoxin-3 (Prx-3), to investigate the mechanism by which toxic properties of ROS were up-regulated in mitochondria of damaged nerve cells [1].
  • Immunohistochemical analysis revealed that Prx-3 protein exists in mitochondria of rat hippocampus, whereas we found a significant decrease in Prx-3 mRNA and protein levels associated with an increase in nitrated proteins in the rat hippocampus injured by microinjection of ibotenic acid [1].
  • Malate dehydrogenase, peroxiredoxin 3, vacuolar ATP synthase subunit beta and mitogen-activated protein kinase kinase 1 were found to have altered expression levels in the groups treated with antipsychotics compared with the matched controls [2].
