AB  - Antidepressants affect glucocorticoid receptor (GR) functioning partly through modulation of its phosphorylation but their effects on mitochondrial GR have remained undefined. We investigated the ability of chronic fiuoxetine treatment to affect chronic stress-induced changes of mitochondrial GR and its phosphoisoforms (pGRs) in the prefrontal cortex and hippocampus of female and male rats. Since mitochondrial GR regulates oxidative phosphorylation, expression of mitochondrial-encoded subunits of cytochrome (cyt) c oxidase and its activity were also investigated. Chronic stress caused accumulation of the GR in mitochondria of female prefrontal cortex, while the changes in the hippocampus were sex-specific at the levels of pGRs. Expression of mitochondrial COXs genes corresponded to chronic stress-modulated mitochondrial GR in both tissues of both genders and to cyt c oxidase activity in females. Moreover, the metabolic parameters in stressed animals were affected by fiuoxetine therapy only in the hippocampus. Namely, fluoxetine effects on mitochondrial COXs and cyt c oxidase activity in the hippocampus seem to be conveyed through pGR232 in females, while in males this likely occurs through other mechanisms. In summary, sex-specific regulation of cyt c oxidase by the stress and antidepressant treatment and its differential convergence with mitochondrial GR signaling in the prefrontal cortex and hippocampus could contribute to clarification of sex-dependent vulnerability to stress-related disorders and sex-specific clinical impact of antidepressants.

AB  - Plastic response and successful adaptation to stress are of particular importance in the hippocampus, where chronic stress may cause cell death instead of neural remodeling. Structural modifications that occur both in the brain of depressed patients and animal stress models may be reversed by antidepressants. Since morphological changes induced by stress and/or antidepressants could be mediated by presynaptically located proteins, determining the levels of these proteins may be a useful way to identify molecular changes associated with synaptic plasticity. In this study we analyzed the effects of chronic (six-week) social isolation and long-term (three-week) fluoxetine treatment on molecular markers of plasticity and apoptosis in the hippocampus of Wistar rats. Compartmental redistribution of NF kappa B transcription factor involved in the regulation of plasticity and apoptosis was also examined. To establish whether social isolation is able to evoke behavioral-like effects, which might be related to the observed molecular changes, we performed the forced swimming test. The results show that synaptosomal polysialic neural cell adhesion molecule (PSA-NCAM), a molecular plasticity marker, was increased in the hippocampus of chronically isolated rats, while subsequent treatment with fluoxetine set it at the control level. In addition, analysis of cytoplasm/mitochondria redistribution of apoptotic proteins Bax and Bcl-2 after exposure to chronic isolation stress, revealed an increase in Bcl-2 protein expression in both compartments, while fluoxetine enhanced the effect of stress only in the mitochondria. The observed alterations at the molecular level were accompanied by normalization of stress-induced behavioral changes by fluoxetine. (C) 2011 Elsevier Inc. All rights reserved.

AB  - The prefrontal cortex is the brain region sensitive to detrimental effects of stress and even mild stress can rapidly impair its function. Aside from initiating proadaptive neuroplastic changes in the prefrontal cortex, chronic stress may also increase vulnerability of cortical neurons to apoptosis. Understanding the mechanism of plasticity and apoptotic processes is of immense importance for therapy of stress-related psychiatric disorders. In this study we tested whether molecular alterations in the prefrontal cortex, which occurred upon chronic social isolation, could be influenced by a prolonged fluoxetine treatment. We analyzed the expression of synaptic plasticity and apoptotic molecular markers in the prefrontal cortex of young-adult male Wistar rats exposed to 6-week social isolation with and without fluoxetine treatment during the last 3 weeks. Compartmental redistribution of NF kappa B transcription factor, involved in regulation of plasticity and apoptosis, was also examined. The level of synaptosomal polysialic neural cell adhesion molecule(PSA-NCAM) was increased in the prefrontal cortex of isolated rats as compared to untreated controls. Treatment with fluoxetine reduced the PSA-NCAM level only in isolated animals. In addition, mitochondrial Bax protein was elevated by chronic social isolation, while fluoxetine failed to abolish this effect. Inspite of elevated Bcl-2 in the mitochondria, the calculated Bax/Bcl-2 ratio and concomitant absence of NF kappa B activation pointed to initiation of apoptotic signaling in the prefrontal cortex. The result simply that fluoxetine influences plasticity in the prefrontal cortex of chronically isolated rats and fails to prevent stress-induced initiation of apoptosis in this brain structure.

AB  - Alterations in the antioxidative defense parameters upon chronic stress are considered critical for pathophysiology of stress related psychiatric disorders, and their status in blood serves as biomarker for effects of pharmacological treatments. The present study was designed to investigate the modulation of erythrocyte antioxidant enzymes (AOEs): CuZn superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GLR) activities and their protein expression in Wistar male rats subjected to chronic psychosocial isolation and/or to pharmacological treatment with fluoxetine. Chronically isolated animals exhibited decreased levels of serum corticosterone, as opposed to other chronic stress paradigms. In addition to that, SOD, CAT and GPx status was not altered either by chronic psychosocial isolation or by fluoxetine treatment. In contrast, GLR activity and its protein level were both markedly reduced by fluoxetine. Since, GLR is crucial for overall oxido-reductive balance through maintaining optimal ratio of reduced/oxidized glutathione level (GSH/GSSG) in erythrocytes, these results could indicate that in spite of numerous beneficial effects of fluoxetine, it may compromise both haemoglobin function and oxygen transport.

AB  - Gender-related differences in dexamethasone binding to corticosteroid receptors (CR) and in glucocorticoid receptor (GR) protein level in the pituitary, hypothalamus, hippocampus and prefrontal cortex were studied before and after antidepressant fluoxetine administration to both unstressed and rats exposed to a chronic social isolation stress. Untreated males, in comparison to females, displayed higher hormone-binding capacity of both GR and mineralocorticoid receptor (MR) in the hippocampal cytosol, as well as higher GR protein level in the pituitary cytosol. In both genders, dexamethasone binding to MR exceeded that to GR. While fluoxetine treatment and social isolation had no effect on GR activity, the influence on MR was gender-specific. Fluoxetine facilitated MR hormone-binding only in females, increasing the MR/GA activity ratio. In contrast, after a 6-week isolation of males, MR binding capacity was diminished and MR/GR ratio inverted in favor of GR In addition, fluoxetine induced elevation of cytosolic GR protein level in the pituitary and hypothalamus, the latter change being gender-specific. The results point to gender-related differences in the CRs functioning and suggest that both MR and GR may contribute to well-known sexual dimorphism in vulnerability to stress and stress-related disorders and in the outcome of antidepressant treatment.

AB  - Selective serotonin reuptake inhibitors (SSRI) are a treatment of choice for stress related disorders including clinical depression and a range of anxiety-related disorders. In the experimental animals, chronic stress paradigms are considered as a model of depression, and in that context are used for examining the effects of different drug treatments. The present research was designed to investigate the effect of SSRI fluoxetine on antioxidant status and apoptotic signaling in Wistar rat liver, which is a central organ for activation and detoxification of many xenobiotics and reactive oxygen species. We also investigated whether chronic fluoxetine treatment exhibits the same effects in the liver of control animals vs. animals stressed by chronic psychosocial isolation. Our results revealed that fluoxetine downregulated the activity of superoxide dismutases and upregulated the activity of glutathione peroxidase in both rat groups, while elevating glutathione reductase activity and total antioxidant status only in stressed animals. These results suggested that fluoxetine interfered with stress-induced pathways of oxidative defense in the liver. In addition, in both experimental groups, fluoxetine induced several hallmarks of apoptosis in the liver, including a decrease in Bcl-2 expression and increased DNA fragmentation. However, apoptotic alterations were more pronounced in stressed animals, suggesting that stress related oxidative damage could have primed apoptotic effects of fluoxetine. (C) 2011 Elsevier B.V.

In the experimental animals, chronic stress paradigms are considered as a model of depression, and in that context are used for examining the effects of different drug treatments. The present research was designed to investigate the effect of SSRI fluoxetine on antioxidant status and apoptotic signaling in Wistar rat liver, which is a central organ for activation and detoxification of many xenobiotics and reactive oxygen species. We also investigated whether chronic fluoxetine treatment exhibits the same effects in the liver of control animals vs. animals stressed by chronic psychosocial isolation. Our results revealed that fluoxetine downregulated the activity of superoxide dismutases and upregulated the activity of glutathione peroxidase in both rat groups, while elevating glutathione reductase activity and total antioxidant status only in stressed animals. These results suggested that fluoxetine interfered with stress-induced pathways of oxidative defense in the liver. In addition, in both experimental groups, fluoxetine induced several hallmarks of apoptosis in the liver, including a decrease in Bcl-2 expression and increased DNA fragmentation. However, apoptotic alterations were more pronounced in stressed animals, suggesting that stress related oxidative damage could have primed apoptotic effects of fluoxetine. (C) 2011 Elsevier B.V.

AB  - Gender-related differences in the expression and functional properties of the hepatic glucocorticoid receptor were studied before and after antidepressant fluoxetine administration to both unstressed and rats exposed to a chronic social isolation stress. Some of the receptor's functional properties, including hormone-binding capacity (B(max)), hormone-binding potency (B(max)/K(D) ratio) and the DNA-binding ability, were found to be sexually dimorphic. Fluoxetine treatment (5 mg/kg body mass, 21 day, intraperitoneally) induced a decrease in B(max) and in the amount of Hsp70 co-immunoprecipitated with the glucocorticoid receptor only in males, and stimulated the association of the receptor with Hsp90 in females. When applied during the last three weeks of the 6-week isolation, fluoxetine parallelly elevated B(max) and the receptor protein level in female animals, while in males diminished B(max) and inhibited association of the receptor with Hsp70. Binding of dexamethasone-receptor complexes both to DNA-cellulose and to isolated liver nuclei did not appear to be a target for fluoxetine action. The results point to sex-related differences in the glucocorticoid receptor functioning and in its response to fluoxetine, and suggest that these differences may contribute to well known sexual dimorphism in the sensitivity to stress, to stress-related disorders and to antidepressant treatment.
