Scholarcy highlights

  • In this study, the effect of α-tocopherol on the antioxidant capacity of rainbow trout was determined
  • The results showed that α-tocopherol significantly activated the CAT, POD and GSSG-Rx enzymes as compared with the enzyme activities found in the controls
  • MDA levels were significantly decreased by α-tocopherol treatment
  • The results suggest that α-tocopherol may have a pro-oxidant tendency at a high dose and cause mild oxidative stress which could modulate signal transduction cascades, redirect gene expression, and influence many cellular responses such as proliferation, differentiation, and reproduction
  • Α-tocopherol should be used carefully in all applications in relation to fish
