Table 2

Short overview for the oxidative stress modifications in some affective disorders in animal models.

Followed diseaseAnimal model/testOxidative disturbances

Bipolar disorderManic phase, induced with amphetamineBrain: ↑ SOD production; ↑ TBARS [90]
↑ protein and lipid oxidative damage [91]
↓ SOD: ↓ CAT specific activity [92]
↑ lipid peroxidation [93]
↑ protein aggregation of 4-HNE (a major product of lipid peroxidation) [94]
Manic phase, chronic amphetamine administrationSubmitochondrial fragments of prefrontal cortex and hippocampus: ↑ superoxide production [91]
↓ GSH-Px; ↓ glutathione; ↓ vitamin C [93]
Manic phase, induced with ouabain↑ TBARS; ↑ superoxide production; ↑ carbonyl content [9598]
↑ SOD; ↓ CAT [95]

DepressionChronic mild stress↑ superoxide in hippocampus; ↑ TBARS in cortex [99]
↓ antioxidant GST gene expression [100]
Olfactory bulbectomy model↓ CAT in blood stream; ↓ GSH; ↓ GSH-Px; ↑ SOD [101]
Chronic unpredictable mild stress (CUMS)↑ liver MDA; ↓ TAC (total antioxidant capability); ↓ GSH; ↓ SOD; ↓ CAT [102]
Swimming restraint↓ plasma GSH; ↓ plasma TBARS [103]

AnxietyFetal alcohol exposureHippocampus, cerebellum: ↑ lipid peroxidation; ↑ protein oxidation; ↓ GSH [104]
Immobilization stress↑ lipid peroxidation; ↑ nitrite; ↓ GSH; ↓ CAT [105]
Chronic social isolationHepatic levels: ↓ GSH; ↓ glutathione reductase; ↑ CAT; ↑ glutathione S-transferase [106]
Ovariectomy-inducedPlasma: ↑ 8-isoprostane; hippocampus: ↑ protein carbonylation [107]
PLTP knock-out model↓ vitamin E; ↑ oxidative stress markers in phospholipid transfer protein knock-out mice [108]
Vit. A subacute supplementation↑ lipid peroxidation; ↑ protein carbonylation; ↑ protein thiol oxidation; SOD and CAT, altered, induced by vitamin A [109]

Posttraumatic stress disorder (PTSD) modelSingle prolonged stressAmygdala: ↓ glutathione reductase; plasma: ↑ 8-isoprostanes levels [110]

Note: SOD: superoxide dismutase; TBARS: thiobarbituric acid reactive substances; CAT: catalase; 4-HNE: 4-hydroxynonenal; MDA: malondialdehyde; 4-HDA: 4-hydroxyalkenals; GSH: glutathione; GHS-Px: glutathione peroxidase; TAC: total antioxidant capacity; GST: glutathione-S-transferase.
