AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - BACKGROUND: Oestradiol is an important regulatory factor with several positive effects on the cardiovascular (CV) system. We evaluated the molecular mechanism of the in vivo effects of oestradiol on the regulation of cardiac inducible nitric oxide (NO) synthase (iNOS) expression and activity. METHODS: Male Wistar rats were treated with oestradiol (40 mg/kg, intraperitoneally) and after 24 h the animals were sacrificed. The concentrations of NO and L-Arginine (L-Arg) were determined spectrophotometrically. For protein expressions of iNOS, p65 subunit of nuclear factor-κB (NFκB-p65), Ras homolog gene family-member A (RhoA), angiotensin II receptor type 1 (AT1R), insulin receptor substrate 1 (IRS-1), p85, p110 and protein kinase B (Akt), Western blot method was used. Coimmunoprecipitation was used for measuring the association of IRS-1 with the p85 subunit of phosphatidylinositol- 3-kinase (PI3K). The expression of iNOS messenger ribonucleic acid (mRNA) was measured with the quantitative real-time polymerase chain reaction (qRT-PCR). Immunohistochemical analysis of the tissue was used to detect localization and expression of iNOS in heart tissue. RESULTS: Oestradiol treatment reduced L-Arg concentration (p<0.01), iNOS mRNA (p<0.01) and protein (p<0.001) expression, level of RhoA (p<0.05) and AT1R (p<0.001) protein. In contrast, plasma NO (p<0.05), Akt phosphorylation at Thr308 (p<0.05) and protein level of p85 (p<0.001) increased after oestradiol treatment. CONCLUSION: Our results suggest that oestradiol in vivo regulates cardiac iNOS expression via the PI3K/Akt signaling pathway, through attenuation of RhoA and AT1R.

AB  - The hippocampus is sensitive to stress which activates norepinephrine terminals deriving from the locus coeruleus. Melatonin exerts positive effects on the hippocampal neurogenic process and on depressive-like behaviour. Thus, in the present study, an examination was made of the effect of chronic melatonin treatment on norepinephrine content, synthesis, uptake, vesicular transport and degradation in the hippocampus of rats exposed to CUMS. This entailed quantifying the norephinephrine, mRNA and protein levels of DBH, NET, VMAT 2, MAO-A and COMT. The results show that CUMS evoked prolonged immobility. Melatonin treatment decreased immobility in comparison with the placebo group, reflecting an antidepressant-like effect. Compared with the placebo group, a dramatic decrease in norepinephrine content, decreased VMAT2 mRNA and protein and increased MAO-A protein levels in the hippocampus of the CUMS rats were observed. However, no significant differences in the levels of DBH, NET, COMT mRNA and protein and MAO-A mRNA levels between the placebo and the stressed groups were found. The results showed the restorative effects of melatonin on the stress-induced decline in the norepinephrine content of the hippocampus. It was observed that melatonin treatment in the CUMS rats prevented the stress-induced decrease in VMAT2 mRNA and protein levels, whereas it reduced the increase of the mRNA of COMT and protein levels of MAO-A. Chronic treatment with melatonin failed to alter the gene expression of DBH or NET in the hippocampus of the CUMS rats. Additionally, the results show that melatonin enhances VMAT2 expression and norepinephrine storage, whilst it reduces norepinephrine degrading enzymes. (C) 2016 Elsevier B.V. and ECNP.

AB  - Knowledge of the antioxidant defense in the stress-responding structures of the CNS is of crucial importance, since oxidative damage is a phenomenon accompanying many stress-related disorders. Regulation of antioxidative and anti-inflammatory defense through Nrf2 (nuclear factor 2 eritroid related factor 2) pathway has emerged as a promising approach for neuroprotection. In this study, we used chronic social isolation of male Wistar rats to induce depressive-like behavior. We hypothesized that Nrf2 Keap1 pathway is compromised in the limbic brain after prolonged stress. Since subcellular trafficking of Nrf2 and its inhibitor Keap1 (Kelch ECH associating protein 1) is essential for the activation of Nrf2, we determined their protein level in cytosolic and nuclear comp and linents of hippocampus and prefrontal cortex (PEG). We also determined mRNA levels of Nr12-regulated genes involved in the production and utilization of glutathione, glutamate cysteine ligase (Gclm), glutathione S-transferase (Gsta3) and glutathione reductase (Gsr). Our results showed that chronic isolation induced anxiety and depressive-like behavior, decreased Nrf2 and in parallel increased Keap1 and nuclear factor kappa B (NF kappa B) in the hippocampus, which were not accompanied by expression profiles of Nrf2-regulated genes. Chronically stressed rats challenged with acute stress failed to induce any response of examined genes in either of brain structures, even though Nrf2/Keap1 was altered, while in naive animals Nrf2 activity corresponded witli an expression of Nrf2-regulated genes. Our results reveal maladaptive character of chronic stress at Nrf2/Keap1 level followed by pro-inflammatory conditions, and suggest a possible role of these alterations in pathogenesis of depressive/anxiety disorders.

AB  - Peripheral inflammation induced by lipopolysaccharide (LPS) causes behavioural changes indicative for depression. The possible mechanisms involve the interference with neuroinflammatory, neuroendocrine, and neurotrophic processes. Apart from heterogeneity in the molecular background, sexual context may be another factor relevant to the manifestation of mood disturbances upon an immune challenge. We investigated sex-dependent effects of a 7-day LPS treatment of adult Wistar rats on depressive-like behaviour and their relation with hypothalamic neuroendocrine factor, corticotrophin-releasing hormone (CRH), proplastic brain-derived neurotropic factor (BDNF), pro-inflammatory cyclooxygenase-2 (COX-2) and nuclear factor kappa beta (NFkB). Also, their regulators, the glucocorticoid receptor (GR) and CCAAT enhancer-binding protein (C/EBP) beta were followed. LPS induced depressive-like behaviour in females was associated with the increased hypothalamic CRH and decreased BDNF, but not with COX-2. These changes were paralleled by an increase in nuclear GR, NFkB and 20 kDa C/EBP beta. LPS also altered behaviour in males and increased CRH expression, but in contrast to females, this was accompanied with the elevated COX-2, accumulation of cytosolic GR and elevated nuclear 38 kDa C/EBP beta and NFkB. In conclusion, depressive-like phenotype induced by LPS in both sexes emerges from similar HPA axis activation and sex-specific alterations of hypothalamic molecular signalling: in males it is related to compromised control of neuroinflamation connected with cytoplasmic GR retention, while in females it is related to diminished proplastic capacity of BDNF. Sex-dependent mechanisms by which inflammation alters hypothalamic processes and cause pathological behaviour in animals, could be operative in the treatment of depression-related brain inflammation.

abstract = "Peripheral inflammation induced by lipopolysaccharide (LPS) causes behavioural changes indicative for depression. The possible mechanisms involve the interference with neuroinflammatory, neuroendocrine, and neurotrophic processes. Apart from heterogeneity in the molecular background, sexual context may be another factor relevant to the manifestation of mood disturbances upon an immune challenge. We investigated sex-dependent effects of a 7-day LPS treatment of adult Wistar rats on depressive-like behaviour and their relation with hypothalamic neuroendocrine factor, corticotrophin-releasing hormone (CRH), proplastic brain-derived neurotropic factor (BDNF), pro-inflammatory cyclooxygenase-2 (COX-2) and nuclear factor kappa beta (NFkB). Also, their regulators, the glucocorticoid receptor (GR) and CCAAT enhancer-binding protein (C/EBP) beta were followed. LPS induced depressive-like behaviour in females was associated with the increased hypothalamic CRH and decreased BDNF, but not with COX-2. These changes were paralleled by an increase in nuclear GR, NFkB and 20 kDa C/EBP beta. LPS also altered behaviour in males and increased CRH expression, but in contrast to females, this was accompanied with the elevated COX-2, accumulation of cytosolic GR and elevated nuclear 38 kDa C/EBP beta and NFkB. In conclusion, depressive-like phenotype induced by LPS in both sexes emerges from similar HPA axis activation and sex-specific alterations of hypothalamic molecular signalling: in males it is related to compromised control of neuroinflamation connected with cytoplasmic GR retention, while in females it is related to diminished proplastic capacity of BDNF. Sex-dependent mechanisms by which inflammation alters hypothalamic processes and cause pathological behaviour in animals, could be operative in the treatment of depression-related brain inflammation.

AB  - Major depression is a very common and serious mood disorder characterized by heterogeneous etiopathology. Treatment of the disease usually involves the use of antidepressant medications whose basic mechanism is achieved via increasing synaptic levels of monoamine neurotransmitters in different brain regions affected by the disease. Currently used antidepressant medications display limited efficacy with a pronounced delay to onset of action, and they all provoke disturbing side effects. With the ultimate goal of uncovering the primary postsynaptic actions that may initiate cellular antidepressive signaling, basic and clinical researches are devoted to studying the effects of antidepressants, particularly those most commonly used, selective serotonin reuptake inhibitors (SSRIs), on the complex signaling network that is known to be altered in depression. This includes the effects of antidepressants on the hypothalamic-pituitaryadrenal axis (HPA) activity, production of neurotrophins and regulation of neurogenesis, pro-inflammatory and anti-inflammatory cytokines, oxidative stress and mitochondrial functioning. Herein, we discuss the latest published data from animal and clinical studies that have examined the effects of different SSRIs on depression-related pathophysiological mechanisms. Special attention will be dedicated to gender-specific effects of SSRIs action and to their adverse effects. © 2015 by Nova Science Publishers, Inc. All rights reserved.

AB  - The early postnatal environment is critical for its capacity to influence adult behavior, and is associated with traits of altered physiological and neurobiological function and long-term predisposition to depression. Here we describe the delayed effects of maternal deprivation (MD) in male and female Wistar pups on their physical development and behavior in adulthood in tasks designed to explore depressive-like (forced swimming test, FST), and anxiety-like behaviors (elevated plus maze, EPM). We observed that MD led to reduced body weight in adulthood, anxiety-like traits in the EPM test and increased activity in the phases of the FST. Particularly, a consistent sexual dimorphism was observed in the responses to MD. A lower increase in body weight during maturation of MD rats was more pronounced in males than in females. MD anxiogenic effects were more pronounced in females, while in FST only MD males showed a marked increase in swimming activity followed by decreased immobility.

AB  - Considerable evidence shows an association of depression with the immune system and emphasizes the importance of gender in the etiology of the disease and the response to inflammatory stimuli. We examined the influence of immune-challenged systems on depressive-like behavior in female rats in the context of gonadal hormones. We used a neuroinflammatory model of depression elicited by lipopolysaccharide (LPS) administration on naive and ovariectomized (OVX) female rats, and examined the effects of estradiol (E2) and/or progesterone (P4) replacement therapy on animal behavior, as assessed by the forced swimming test (FST). We found that LPS and OVX increase immobility in the FST, while LPS also decreased body weight in naive female rats. Further, even though P4 application alone showed beneficial effects on the behavioral profile (it reduced immobility and increased climbing), supplementation of both hormones (E2 and P4) together to OVX rats failed to do so. When OVX rats were exposed to LPS-induced immune challenge, neither hormone individually nor their combination had any effect on immobility, however, their joint supplementation increased climbing behavior. In conclusion, our study confirmed that both LPS and OVX induced depressive-like behavior in female rats. Furthermore, our results potentiate P4 supplementation in relieving the depressive-like symptomatology in OVX rats, most likely through fine-tuning of different neurotransmitter systems. In the context of an activated immune system, the application of E2 and/or P4 does not provide any advantageous effects on depressive-like behavior.

AB  - A growing body of evidence indicates that mitogen-activated protein kinase (MAPK) participates in various stress-induced responses and is considered to be one of the pathophysiological mechanisms in depression. Surprisingly, the effect of antidepressants on MAPKs is almost unexplored, particularly from the perspective of sexes. The present study investigates the cytoplasm-nuclear distribution of MAPK family, c-Jun N-terminal kinases (JNKs) 1, 2 and 3; extracellular signal-regulated kinases (ERKs) 1 and 2; and p38 kinases, as well as their phosphoisoforms in the hippocampus of chronically stressed female and male rats and upon chronic fluoxetine treatment. Additionally, we analysed crosstalk between MAPK signalling and depressive-like behaviour which correlated with brain-derived neurotrophic factor (BDNF) expression. Our results emphasize a gender-specific and compartment-dependent response of MAPKs to stress and fluoxetine. In females, stress decreased pp38 and pJNK and induced cytosolic retention of pERKs which reduced all nuclear pMAPKs. These changes correlated with altered BDNF expression and behaviour. Similarly, in males, stress decreased pp38 but promoted nuclear translocation of pJNKs and pERKs. These stress alterations of pMAPKs in males were not associated with BDNF expression and depressive-like behaviour. Fluoxetine treatment in stressed females upregulated whole pMAPK signalling particularly those in nucleus which was followed with BDNF expression and normalization of behaviour. In stressed males, fluoxetine affected only cytosolic pJNKs, while nuclear pMAPK signalling and BDNF expression were unaffected even though fluoxetine normalized behaviour. Overall, our results suggest existence of gender-specific mechanism of fluoxetine on nuclear pMAPK/BDNF signalling and depressive-like behaviour and reinforce the antidepressant dogma that females and males respond differently to certain antidepressants.

AB  - Introduction: We investigated the effects of ghrelin on protein expression of the liver antioxidant enzymes superoxide dismutases (SODs), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR), nuclear factor kappa B (NF kappa B) and inducible nitric oxide synthase (iNOS). Furthermore, we aimed to investigate whether extracellular regulated protein kinase (ERK1/2) and protein kinase B (Akt) are involved in ghrelin-regulated liver antioxidant enzymes and iNOS protein expression. Material and methods: Male Wistar rats were treated with ghrelin (0.3 nmol/5 mu l) injected into the lateral cerebral ventricle every 24 h for 5 days, and 2 h after the last treatment the animals were sacrificed and the liver excised. The Western blot method was used to determine expression of antioxidant enzymes, iNOS, phosphorylation of Akt, ERK1/2 and nuclear factor kappa B (NF kappa B) subunits 50 and 65. Results: There was significantly higher protein expression of CuZnSOD (p LT 0.001), MnSOD (p LT 0.001), CAT (p LT 0.001), GPx, (p LT 0.001), and GR (p LT 0.01) in the liver isolated from ghrelin-treated animals compared with control animals. In contrast, ghrelin significantly (p LT 0.01) reduced protein expression of iNOS. In addition, phosphorylation of NF kappa B subunits p65 and p50 was significantly (p LT 0.001 for p65; p LT 0.05 for p50) reduced by ghrelin when compared with controls. Phosphorylation of ERK1/2 and of Akt was significantly higher in ghrelin-treated than in control animals (p LT 0.05 for ERK1/2; p LT 0.01 for Akt). Conclusions: The results show that activation of Akt and ERK1/2 is involved in ghrelin-mediated regulation of protein expression of antioxidant enzymes and iNOS in the rat liver.

AB  - Aim: The aim of this pilot study was to investigate possible associations of LEP promoter polymorphism LEP G-2548A and obesity-associated metabolic and antropometric parameters in obese population. Materials and methods: Group of 31 patients with hyperalimentary type of obesity (mean age: 39.26 +/- 11.45 years; BMI: 41.51 +/- 9.22 kg/m(2)) and 36 healthy, nonobese, normal weight subjects (mean age: 33.55 +/- 6.46 years; BMI: 22.63 +/- 1.94 kg/m(2)) were studied. Blood samples were collected for DNA isolation, serum leptin and serum lipids measurements. LEP G-2548A genotypes were determined by PCR restriction fragment length polymorphism based analyses. Results: No significant differences in genotype and allele frequencies of the LEP G-2548A polymorphism were detected between obese and normal weight subjects. No association was found between this polymorphism and BMI. Obese subjects had statistically significant increase in serum leptin levels compared with control, while no association between leptin concentration and LEP polymorphism LEP G-2548A was found. There is a statistically significant association of LEP G-2548A genotypes with LDL (p LT 0.05), LDL/HDL ratio (p LT 0.001), apoB (p LT 0.01), body weight (p LT 0.001) and waist circumference (p LT 0.001). Conclusion: Our findings indicate that there is an association between LEP G-2548A polymorphism and metabolic and anthropometric parameters in obese patients in a Serbian population.

AB  - The neuropeptide oxytocin has been shown to influence on neuroendocrine function. The aim of the present study was to investigate the effect of peripheral oxytocin treatment on the synthesis, uptake and content of adreno-medullary catecholamine. For this purpose oxytocin (3.6 mu g/100 g body weight, s.c) was administrated to male rats once a day over 14 days. In order to assess the effect of peripheral oxytocin treatment on adreno-medullary catecholamine we measured epinephrine and norepinephrine content and gene expression of tyrosine hydroxylase (TH), norepinephrine transporter (NET) and vesicular monoamine transporter 2 (VMAT2) in the adrenal medulla. Our results show a significant increase of epinephrine (1.7-fold, p LT 0.05) and norepinephrine (1.5-fold, p LT 0.05) content in oxytocin treated animals compared to saline treated ones. Oxytocin treatment had no effect either on mRNA or protein level of TH and NET. Under oxytocin treatment the increase in VMAT2 mRNA level was not statistically significant, but it caused a significant increase in protein level of VMAT2 (3.7-fold, p LT 0.001). These findings indicate that oxytocin treatment increases catecholamine content in the rat adrenal medulla modulating VMAT2 expression. (C) 2013 Elsevier Inc. All rights reserved.

AB  - Background: Oxidative stress is reliably observed in major depressive disorder (MDD). However, molecular data on the principal cellular redox-sensitive transcriptional factors and the levels of their downstream-regulated antioxidant enzymes in MDD are scarce. Methods: In the peripheral blood mononuclear cells (PBMC) of subjects with a current episode of MDD (n = 30) and healthy controls (n = 35), we investigated alterations in the levels of redox-sensing nuclear factor (erythroid-derived 2)-like 2 (Nrf2) protein, its inhibitor Keap1, and nuclear factor-kappa B (NF-kappa B), along with their cognate downstream effectors, the antioxidant enzymes (AOEs): manganese and copper zinc superoxide dismutase (MnSOD and CuZnSOD, respectively), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GLR). Results: MDD subjects exhibited higher levels of Nrf2 and its regulator Keap1, as well as NF-kappa B in the cytoplasm of PBMC compared to controls. This state was further reflected by increased levels of MnSOD, CuZnSOD and CAT proteins and by the lack of correlation between MnSOD and CAT, which could indicate impaired oxidative detoxification capacity in MDD patients. Moreover, increased levels of MnSOD, CuZnSOD and CAT in MDD patients positively correlated with levels of Nrf2, while increased levels of SODs were also positively related to NF-kappa B. There were no differences regarding the levels of GPx and GLR proteins, but the ratio of GLR/GPx was reduced, suggesting diminished capacity of GPx in antioxidative defence in PBMC of MDD subjects. Conclusion: These data provide evidence that MDD is characterized by up-regulation of redox-sensitive transcriptional factors (Nrf2 and NF-kappa B) and AOEs (MnSOD, CuZnSOD and CAT), indicating pro-oxidative state in the PBMC of MDD patients.

AB  - In this study, we examined the influence of immunity on depressive-like
behavior in females in the context of gonadal hormones. We used
neuroinflammatory model of depression elicited by lipopolysaccharide
(LPS) administration on naïve and ovariectomozed (OVX) females and
examined the effects of estradiol (E2) and/or progesterone (P4) replacement
therapy on Wistar rat behavior. LPS induced depressive–like behavior in
both naïve and OVX females. Our behavioral data indicated that E2 and P4
applied alone had opposite effects compared to the E2/P4 combination. The
supplementation of both hormones attenuates detrimental effects of LPSinduced
inflammation, particularly through stimulation of noradrenergic
transmission. Overall immune challenge with LPS is able to induce
depressive-like behavior either of naïve or ovariectomized females,
particularly depending on ovarian hormones background.

The incubation of rat VSMC with thrombin (1 U/ml) for 5 min resulted in significant (p LT 0.001) increase of ERK1/2 phosphorylation by 8.7 +/- A 0.9-fold, EGFR phosphorylation by 8.5 +/- A 1.3-fold (p LT 0.001) and DNA synthesis by 3.6 +/- A 0.4-fold (p LT 0.001). Separate 30-min pretreatments with EGFR tyrosine kinase irreversible inhibitor, 10 A mu M PD169540 (PD), and 20 A mu M anti-HB-EGF antibody significantly reduced thrombin-stimulated EGFR and ERK1/2 phosphorylation by 81, 72 % and by 48 and 61 %, respectively. Furthermore, the same pretreatments with PD or anti-HB-EGF antibody reduced thrombin-induced VSMC proliferation by 44 and 45 %, respectively. In addition, 30-min pretreatments with 10 A mu M specific MMP-2 inhibitor significantly reduced thrombin-stimulated phosphorylation of both EGFR and ERK1/2 by 25 %. Moreover, the same pretreatment with MMP-2 inhibitor reduced thrombin-induced VSMC proliferation by 45 %. These results show that the thrombin-induced DNA synthesis correlates with the level of ERK1/2 activation rather than EGFR activation. These results further suggest that thrombin acts through EGFR and ERK 1/2 signaling pathways involving MMP-2 to upregulate proliferation of VSMC.

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  - The aim of this study was to examine whether the thermogenic potential of rat interscapular brown adipose tissue (IBAT) changes in response to acute and/or chronic exposure to non-thermal stressors (immobilization and isolation), by measuring the uncoupling protein 1 (UCP-1) content, MAO-A, SOD and CAT activities, as well as the number of IBAT sympathetic noradrenaline-containing nerve fibers. Both acute immobilization (2 h) and chronic isolation (21 days), as well as their combined effects, significantly increased the IBAT UCP-1 content in comparison to non-stressed animals. When applied individually, stressors increased the number of sympathetic fibers in comparison to controls, whereas in combination they decreased it. The activity of IBAT monoamine oxidase-A (MAO-A) decreased under the influence of each stressor independent of its type or duration. SOD activity coincided with MAO-A decrement, whereas CAT activity had an opposite pattern of changes. We conclude that acute and chronic exposure to non-thermal stressors, immobilization and isolation, respectively, affect the metabolic potential of rat IBAT, judging by the increase in UCP-1 content and sympathetic outflow. However, when acute immobilization was applied as a novel stressor to previously chronically isolated animals, an increase in the UCP-1 content was accompanied by a lower IBAT sympathetic outflow, suggesting that IBAT metabolic function under various stress condition is not solely dependent on SNS activity.

AB  - Chronic psychosocial isolation stress (CPSI) modulates glucocorticoid receptor (GR) functioning in Wistar male rat hippocampus (HIPPO) through alteration of nuclear GR phosphorylation and its upstream kinases signaling, which parallels animal depressive-like behavior. The current study investigated potential gender specificities regarding the effect of chronic therapy by an antidepressant fluoxetine (FLU) on GR signaling in HIPPO and depressive-like behavior in CPSI animals. FLU was administrated to female and male naive or CPSI rats for 21 days and GR protein, its phosphorylation status and upstream kinases, as well as GR and BDNF mRNA were followed in HIPPO together with animal serum corticosterone (CORT) and depressive-like behavior. The results showed that CPSI increased immobility in males versus hyperactivity in females and disrupted nuclear pGR232-Cdk5 pathway and JNK signaling in a gender-specific way. In contrast, in both genders CPSI increased the nuclear levels of GR and pGR246 but decreased CORT and mRNA levels of GR and BDNF. Concomitant FLU normalized the depressive-like behavior and altered the nuclear pGR232-Cdk5 signaling in a gender-specific manner. In both females and males, FLU reversed the nuclear levels of GR and pGR246 without affecting CORT and GR mRNA levels. In contrast, FLU exhibited gender-specific effect on BDNF mRNA in CPSI animals, by increasing it in females, but not in males. In spite of normalization the total nuclear GR level upon FLU treatment in both gender, down-regulation of GR mRNA is possibly maintained through prevalence of pGR232 isoform only in males. The gender-specific alterations of pGR232-Cdk5 signaling and BDNF gene expression in HIPPO and normalization of depressive-like behavior upon FLU treatment distinguishes this signaling pathway as potential future antidepressant target for gender-specific therapy of stress related mood disorders.

AB  - The mechanism of maladaptive chronic stress response involves altered phosphorylation of the glucocorticoid receptor (GR). In this study, we investigated if important depressogenic vulnerability factors, such as neuroticism and self-reports of negative affective states, may be associated with alterations in levels of the GR and GR phosphoisoforms in peripheral blood mononuclear cells (PBMC) of healthy adults. In 21 women and 16 men we evaluated PMBC levels of total GR (tGR), GR phosphorylated at serine 211 (pGR-S211) and serine 226 (pGR-S226) and correlated these data with personality traits and current reports of stress, anxiety and depression. Also, we assessed plasma cortisol levels in all tested subjects. Our results showed that in women nuclear pGR-S226 was positively correlated with neuroticism and current reports of depression, anxiety and stress, while the ratio of nuclear pGR-S211/pGR-S226 was negatively correlated with reports of depression. None of the aforementioned correlations were significant in men. No significant relations between cortisol levels and any of GR parameters were observed. These preliminary findings highlight the value of GR phosphorylation-related research in identifying molecular biomarkers of depressogenic vulnerability, at least in women.

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  - Chronic stress is a contributing risk factor in the development of psychiatric illnesses, including depressive disorders. The mechanisms of their psychopathology are multifaceted and include, besides others, alterations in the brain plasticity. Previously, we investigated the effects of chronic social stress in the limbic brain structures of Wistar rats (hippocampus, HIPPO, and prefrontal cortex, PFC) and found multiple characteristics that resembled alterations described in some clinical studies of depression. We extended our investigations and followed the behavior of stressed animals by the open field test (OFT) and forced swimming test (FST), and the expression and polysialylation of synaptic plasticity markers, neural cell adhesion molecule (NCAM) and L1, in the HIPPO and PFC. We also determined the adrenal gland mass and plasma corticosterone (CORT) as a terminal part of the hypothalamic-pituitary-adrenal axis activity. Our data indicated that stressed animals avoided the central zone in the OFT and displayed decreased swimming, but prolonged immobility in the FST. The animals exhibited marked hypertrophy of the adrenal gland cortex, in spite of decreased serum CORT. Simultaneously, the stressed animals exhibited an increase in NCAM mRNA expression in the HIPPO, but not in the PFC. The synaptosomal NCAM of the HIPPO was markedly polysialylated, while cortical PSA-NCAM was significantly decreased. The results showed that chronic social isolation of Wistar rats causes both anxiety-like and depression-like behavior. These alterations are parallel with molecular changes in the limbic brain, including diminished NCAM sialylation in the PFC. Together with our previous results, the current observations suggest that a chronic social isolation model may potentially be used to study molecular mechanisms that underlie depressive symptomatology.

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  - The response of hypothalamo-pituitary-adrenocortical (HPA) axis to different stressors depends on numerous stimulatory and inhibitory signals gathering from various parts of the brain to the hypothalamic nuclei. The present study was aimed at determining whether catecholamines (CA) and vasopressin (VP) play the role in the specific regulation of adrenocorticotropic hormone (ACTH) secretion under the influence of thermal stressors, cold (+4 degrees C) and heat (+38 degrees C), applied acutely for 1 h or repeatedly during 7 and 14 day (1 h daily). The results showed that following acute exposure to those stressors, hypothalamic dopamine (DA), noradrenaline (NA) and adrenaline (ADR) concentrations were significantly decreased as compared to non stressed controls. The prolonged exposure to either of the two stressors left hypothalamic CA concentration unaffected. The amount of pituitary VP significantly increased only under the influence of acute heat stress. Prolonged exposure to both stressors induced significant decrease in the pituitary VP content. Unlike the heat, the cold-caused changes in circulating VP did not follow those in the pituitary. The applied stressors significantly increased the amount of the pituitary V1b receptor (V1bR) mainly present at the surface of corticotrophs, depending on both duration of exposure and nature of stressor. Additionally, both cold and heat specifically induced an increase in blood ACTH. In conclusion, this studys results suggest that the role of VP in the regulation of the ACTH secretion in response to cold and heat depends on the type of stressor, whereas the role of the CA depends on the manner of exposure.

AB  - The heart is an organ especially sensitive to the sympathetic overstimulation and therefore to the influence of stressors and hypertension. The aim of the present study was to investigate the effect of two distinct types of stressors, acute immobilization (2 h) and chronic isolation stress (21 days), as well as their combined effect on the activity of monoamine oxidase (MAO), superoxide dismutase, catalase (CAT) and the ascorbic acid (AA) content in the heart of normotensive and spontaneously hypertensive rats (SHR). The results obtained show that in basal conditions heart MAO and CAT activity (p LT 0.05), as well as AA concentration (p LT 0.01) were higher in SHR than in normotensive ones. The acute immobilization significantly decreased heart MAO activity in both examined strains (p LT 0.01). On the other hand, chronic isolation, separately or in combination with immobilization, did not affect this enzyme, in the heart of either hypertensive or normotensive rats, which was associated with the reduced antioxidative protection (p LT 0.01, p LT 0.05).
