“…Antioxidants provide cells with a comprehensive defense from ROS-induced damage. These defenses include low molecular weight compounds (e.g., glutathione and ascorbate) and antioxidant enzymes (e.g., superoxide dismutase, catalase, and glutathione-dependent antioxidant enzymes) (Grim et al 2013). Glutathione (GSH), a tri-peptide that can neutralize ROS, also serves as a critical cofactor for several glutathione-dependent antioxidant enzymes (Pacitti et al 2013).…”

The present study was conducted to evaluate the effects of vaccination against furunculosis on responses of oxidative stress and antioxidant defenses in rainbow trout Oncorhynchus mykiss muscle, gills, liver, and brain tissues. The oxidative stress markers (malondialdehyde and carbonyl derivatives of protein oxidative destruction levels), antioxidant defenses (superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase), and total antioxidant capacity in different tissues of rainbow trout were measured. Our data showed that exposure of trout to vaccine against furunculosis produced changes (either increase or decrease) in oxidative stress and antioxidant enzymes responses, and these responses showed marked organ differences, associated with tissue patterns. Our study demonstrated that vaccinated trout showed alteration in antioxidant defenses and oxidative stress responses, with higher severity in the liver, compared with other tissues. Our data also suggest that vaccination against furunculosis induced lipid peroxidation in gill and liver tissues. However, muscle and brain tissue are capable of restoring its pro- and antioxidant balance after vaccination.

“…1, 3). Grim et al (2013) suggested that because activities of glutathione-dependent enzymes were unaffected by temperature acclimation, the protein levels of glutathione-dependent antioxidants may limit the activity of the enzymatic system at lower temperatures. Similarly, in other studies, SOD and CAT activities were unchanged in fishes following temperature acclimation (Leggatt et al, 2007;Grim et al, 2010).…”

Copper has been widely used to control algae and pathogens in fish culture ponds. However, its toxic effects on fish depend not only on its concentration in the water but also on the water quality. A laboratory experiment was conducted to assess copper toxicity in the black rockfish Sebastes schlegeli using a panel of antioxidant enzymes, including glutathione (GSH), glutathione S-transferase (GST), glutathione peroxidase (GPx), glutathione reductase (GR) and superoxide dismutase (SOD), at different levels of copper at three water temperatures (WT, 18, 23, 28°C) for 4 days. After exposure to two copper concentrations (100 and 200 μg/L), GSH levels and GST activities increased significantly, depending on WT (P < 0.05) in the liver, gill, and kidney of the black rockfish. GPx and SOD activities decreased significantly with both increasing WT and copper treatment in the organs of black rockfish (P < 0.05). These changes can be seen as initial responses to temperature stress and as a sustained response to copper exposure. This also indicates that GSH and related enzymes activities were sensitive indexes to stress by toxicants such as copper. The present findings suggest that simultaneous stress due to temperature change and copper exposure can accelerate changes in enzymes activities in the black rockfish. This provides another example of synergism between environmental temperature and pollutants, which may have important implications for the survival of fish in polluted environments during seasonal warming and/or global climate change.

“…This cellular damage causes a shift in the net charge of the cell and changes the osmotic pressure, which leads to swelling and eventually cell death (Nijveldt et al 2001). ROS also can play a beneficial role in cells by contributing to pathways of intracellular signalling and redox regulation (Grim et al 2013). Their damage to the biological components is balanced by the activities of many cellular defence mechanisms (Stohs et al 2000).…”

ABSTRACT:In this work we compared two species of fish with different feeding habits: Flathead mullet (Mugil cephalus) and Gilthead sea bream (Sparus aurata). The aim of this study was to evaluate total oxidant status (TOS), total antioxidant capacity (TAC) and TOS/TAC ratio (OSI), in order to highlight the presence of any differences and correlations in these two different species of fish. Thirty adult fish of Mugil cephalus and thirty of Sparus aurata were used. From each fish 0.6 ml of blood was collected. TOS and TAC indicators were measured in serum obtained from samples previously clotted and centrifuged. Our results showed statistically significant differences between the two species in TAC. TOS and OSI did not show significant differences between Gilthead sea bream and Flathead mullet. A positive relationship between TOS and TAC was found in Flathead mullet (Mugil cephalus), and a negative relation between TOS and TAC in Gilthead sea bream (Sparus aurata). Our study indicates that the oxidative status and the relationship between total oxidant status (TOS) and total antioxidant capacity (TAC) in serum are probably dependent on the fish species and are affected by different feeding habits.Keywords: total oxidant status; total antioxidant capacity; teleost species; redox balance List of abbreviations FRAP = ferric reducing antioxidant potential, ROM = reactive oxygen metabolites, ROS = reactive oxygen species, TAC = total antioxidant capacity, TOS = total oxidant status, OSI = oxidative stress index (TOS/TAC ratio)
