Glutathione metabolism in Cryptocaryon irritans involved in defense against oxidative stress induced by zinc ions

open access: yesParasites & Vectors, 2022
Background Cryptocaryon irritans is a fatal parasite for marine teleosts and causes severe economic loss for aquaculture. Galvanized materials have shown efficacy in controlling this parasite infestation through the release of zinc ions to induce ...

Effects of trichotecene mycotoxins on gene expression and activity of glutathione redox system in common carp (Cyprinus carpio L.)

open access: yesFrontiers in Marine Science, 2015
The purpose of present study was to evaluate the short- and long-term effects of T-2 toxin and deoxynivalenol (DON) in common carp. Short-term effect was evaluated using single oral doses of DON or T-2 toxin of 0.25, 0.50 or 3.00 mg/kg b.w ...

Human umbilical cord mesenchymal stem cells derived exosome shuttling mir-129-5p attenuates inflammatory bowel disease by inhibiting ferroptosis

open access: yesJournal of Nanobiotechnology, 2023
Background Ferroptosis, a unique form of non-apoptotic cell death, is dependent on iron and lipoperoxidation, and has been shown to be associated with the pathogenesis of inflammatory bowel disease (IBD).
