Abstract
Ischaemic stroke is an acute interruption of the blood supply to the brain, which leads to rapid irreversible damage to nerve tissue. Ischaemic stroke is accompanied by the development of neuroinflammation and neurodegeneration observed around the affected brain area. Heat shock protein 70 (Hsp70) facilitates cell survival under a variety of different stress conditions. Hsp70 may be secreted from cells and exhibits cytoprotective activity. This activity most likely occurs by decreasing the levels of several proinflammatory cytokines through interaction with a few receptors specific to the innate immune system. Herein, we demonstrated that intranasal administration of recombinant human Hsp70 shows a significant twofold decrease in the volume of local ischaemia induced by photothrombosis in the mouse prefrontal brain cortex. Our results revealed that intranasal injections of recombinant Hsp70 decreased the apoptosis level in the ischaemic penumbra, stimulated axonogenesis and increased the number of neurons producing synaptophysin. Similarly, in the isolated crayfish stretch receptor, consisting of a single sensory neuron surrounded by the glial envelope, exogenous Hsp70 significantly decreased photoinduced apoptosis and necrosis of glial cells. The obtained data enable one to consider human recombinant Hsp70 as a promising compound that could be translated from the bench into clinical therapies.

J Affect Disord 2020; 276:525-536.

Abstract
BACKGROUND Recent studies have suggested the role of mammalian target of rapamycin complex 1 (mTORC1) in the pathophysiology of depression. Although venlafaxine was thought to be a serotonin and norepinephrine reuptake inhibitor (SNRI), its pharmacological mechanism remain elusive. In this study, the effects of venlafaxine on the mTORC1 system were studied in both chronic unpredictable mild stress (CUMS) and chronic social defeat stress (CSDS) models. METHOD First, we examined whether repeated venlafaxine treatment reversed the effects of CUMS and CSDS on the mTORC1 signaling cascade in both the hippocampus and medial prefrontal cortex (mPFC). Second, several selective pharmacological inhibitors of the mTORC1 system, including rapamycin, LY294002 and U0126, were used together to determine whether the protective effects of venlafaxine against the CUMS and CSDS models were prevented by mTORC1 system blockade. Finally, genetic knockdown of mTORC1 by mTORC1-shRNA was further adopted to test whether mTORC1 was necessary for the anti-stress effects of venlafaxine in mice. RESULT Our results showed that the decreasing effects of CUMS and CSDS on the mTORC1 signaling cascade in the hippocampus and mPFC were restored by venlafaxine, and the use of rapamycin, LY294002, U0126 and mTORC1-shRNA fully abolished the anti-stress actions of venlafaxine in mice. CONCLUSION The mTORC1 system is involved in the pharmacological mechanism of venlafaxine.

Localization and Expression of Sirtuins 1, 2, 6 and Plasticity-Related Proteins in the Recovery Period after a Photothrombotic Stroke in Mice. J Stroke Cerebrovasc Dis 2020; 29:105152.

Abstract
Sirtuins, class III histone deacetylases, are involved in the regulation of tissue repair processes and brain functions after a stroke. The ability of some isoforms of sirtuins to circulate between the nucleus and cytoplasm may have various pathophysiological effects on the cells. In present work, we focused on the role of non-mitochondrial sirtuins SIRT1, SIRT2, and SIRT6 in the restoration of brain cells following ischemic stroke. Here, using a photothrombotic stroke (PTS) model in mice, we studied whether local stroke affects the level and intracellular localization of SIRT1, SIRT2, and SIRT6 in neurons and astrocytes of the intact cerebral cortex adjacent to the ischemic ipsilateral hemisphere and in the analogous region of the contralateral hemisphere at different time points during the recovery period after a stroke. We evaluated the co-localization of sirtuins with growth-associated protein-43 (GAP-43), the presynaptic marker synaptophysin (SYN) and acetylated α-tubulin (Ac-α-Tub), that are associated with brain plasticity and are known to be involved in brain repair after a stroke. The results show that during the recovery period, an increase in SIRT1 and SIRT2 levels occurred. The increase of SIRT1 level was associated with an increase in synaptic plasticity proteins, whereas the increase of SIRT2 level was associated with an acetylated of α-tubulin, that can reduce the mobility of neurites. SIRT6 co-localized with GAP-43, but not with SYN. Moreover, we showed that SIRT1, SIRT2, and SIRT6 are not involved in the PTS-induced apoptosis of penumbra cells. Taken together, our results suggest that sirtuins functions differ depending on cell type, intracellular localization, specificity of sirtuins isoforms to different substrates and nature of post-translational modifications of enzymes.

Abstract
Vascular depression (VD), a subtype of depression, is caused by vascular diseases or cerebrovascular risk factors. Recently, the proportion of VD patients has increased significantly, which severely affects their quality of life. However, the current pathogenesis of VD has not yet been fully understood, and the basic research is not adequate. In this study, on the basis of the combination of LC-MS-based proteomics and metabolomics, we aimed to establish a protein metabolism regulatory network in a murine VD model to elucidate a more comprehensive impact of VD on organisms. We detected 44 metabolites and 304 proteins with different levels in the hippocampus samples from VD mice using a combination of metabolomic and proteomics analyses with an isobaric tags for relative and absolute quantification (iTRAQ) method. We constructed a protein-to-metabolic regulatory network by correlating and integrating the differential metabolites and proteins using ingenuity pathway analysis. Then we quantitatively validated the levels of the bimolecules shown in the bioinformatics analysis using LC-MS/MS and Western blotting. Validation results suggested changes in the regulation of neuroplasticity, transport of neurotransmitters, neuronal cell proliferation and apoptosis, and disorders of amino acids, lipids and energy metabolism. These proteins and metabolites involved in these dis-regulated pathways will provide a more targeted and credible direction to study the mechanism of VD. Therefore, this paper presents an approach and strategy that was applied in integrative proteomics and metabolomics for research and screening potential targets and biomarkers of VD, which could be more precise and credible in a field lacking adequate basic research.

Effects of "nourishing liver and kidney" acupuncture therapy on expression of brain derived neurotrophic factor and synaptophysin after cerebral ischemia reperfusion in rats. ACTA ACUST UNITED AC 2017; 37:271-278.

Abstract
The aim of the present study was to investigate the effect of "nourishing liver and kidney" acupuncture therapy on motor and cognitive deficits, and the underlying mechanism following cerebral ischemia-reperfusion (I/R) via increasing the expression of brain derived neurotrophic factor (BDNF) and synaptophysin (SYN) in the hippocampus. Healthy adult male SD rats were randomly divided into sham operation group (n=51), model group (n=51), acupuncture group (n=51) and acupuncture control group (n=51). The middle cerebral I/R model was established. Acupunctures were performed in the acupuncture group and acupuncture control group at acupoints of Taixi (K103), Taichong (ST09) of both sides, for 30 min once daily every morning. The animals in the sham operation group and model group were conventionally fed in the cage, without any intervention therapy. The rats of each group were assessed with modified neurological severity scores (mNSS). The expression of BDNF and SYN in the hippocampus was detected by immunohistochemical SP method and the synaptic structure in hippocampus area was assessed morphologically and quantitatively at the 3rd, 7th and 14th day. The Morris water Maze (MWM) test was used to evaluate the rats' learning and memory abilities on the 15th day after acupuncture. The animals in the acupuncture control group and sham operation group presented no neurological deficit. In the acupuncture group, the nerve functional recovery was significantly better than that in the model group at the 7th and 14th day after modeling. The average MWM escape latency in the acupuncture group was shorter than that in the model group at the 3rd, 4th and 5th day. The number of crossings of the platform quadrant in the acupuncture group was significantly more than that in the model group. At the each time point, the expression levels of BDNF and SYN in the hippocampal regions increased significantly in the model group as compared with the sham operation group and the acupuncture control group. In the acupuncture group, the expression levels of BDNF at the 7th and 14th day increased more significantly than those in the model group. In the acupuncture group, the expression levels of SYN at the each time point increased more significantly than those in the model group. The post-synaptic density (PSD) was significantly increased and the synapse cleft width was narrowed in the acupuncture group as compared with other groups. The synaptic curvatures were improved obviously in the acupuncture group in contrast to the model group. It was concluded that the "nourishing liver and kidney" acupuncture therapy has positive effects on behavioral recovery, as well as learning and memory abilities, probably by promoting the expression of BDNF and SYN, and synaptic structure reconstruction in the ipsilateral hippocampus after I/R in rats. The "nourishing liver and kidney" acupuncture therapy can promote the functional recovery in rats after cerebral ischemia injury.

Abstract
Neuromodulators, such as antidepressants, may contribute to neuroprotection by modulating growth factor expression to exert anti-inflammatory effects and to support neuronal plasticity after stroke. Our objective was to study whether early treatment with venlafaxine, a serotonin-norepinephrine reuptake inhibitor, modulates growth factor expression and positively contributes to reducing the volume of infarcted brain tissue resulting in increased functional recovery. We studied the expression of BDNF, FGF2 and TGF-β1 by examining their mRNA and protein levels and cellular distribution using quantitative confocal microscopy at 5 days after venlafaxine treatment in control and infarcted brains. Venlafaxine treatment did not change the expression of these growth factors in sham rats. In infarcted rats, BDNF mRNA and protein levels were reduced, while the mRNA and protein levels of FGF2 and TGF-β1 were increased. Venlafaxine treatment potentiated all of the changes that were induced by cortical stroke alone. In particular, increased levels of FGF2 and TGF-β1 were observed in astrocytes at 5 days after stroke induction, and these increases were correlated with decreased astrogliosis (measured by GFAP) and increased synaptophysin immunostaining at twenty-one days after stroke in venlafaxine-treated rats. Finally, we show that venlafaxine reduced infarct volume after stroke resulting in increased functional recovery, which was measured using ladder rung motor tests, at 21 days after stroke. Our results indicate that the early oral administration of venlafaxine positively contributes to neuroprotection during the acute and late events that follow stroke.

Abstract
BACKGROUND Desvenlafaxine is used as an antidepressant and acts by inhibiting reuptake of serotonin and nor-adrenaline. PURPOSE The safety profile of desvenlafaxine has not yet been established during pregnancy, so we planned this study to see the behavioral changes in pups of mice who received desvenlafaxine during gestational period. METHODS Swiss albino mice were used for the present study. The treated group was given desvenlafaxine orally in the dose of 80 mg/kg from 1(st) to 6(th) day of gestation and other group was given tap water by same route. RESULTS Desvenlafaxine treated mice in group 2, i.e. for the gestation period 1-6 showed increased activity and decrease anxiety in open field and elevated plus maze test as compared to control. However, after chronic exposure for the duration of 18 days the offspring showed increased anxiety and fearfulness as compared to controls. CONCLUSION Above findings suggest that desvenlafaxine have a deleterious effect on brain development, thus resulting in abnormal anxiety states, possibly through altering uptake of serotonin and nor-epinephrine.

Abstract
Recently, it has been proposed that abnormalities in neuronal structural plasticity may underlie the pathogenesis of major depression, resulting in changes in the volume of specific brain regions, including the hippocampus (HIP), the prefrontal cortex (PC), and the amygdala (AMY), as well as the morphology of individual neurons in these brain regions. In the present survey, we compile the data regarding the involvement of the neural cell adhesion molecule (NCAM) protein and its polysialylated form (PSA-NCAM) in the pathogenesis of depression and the mechanism of action of antidepressant drugs (ADDs). Elevated expression of PSA-NCAM may reflect neuroplastic changes, whereas decreased expression implies a rigidification of neuronal morphology and an impedance of dynamic changes in synaptic structure. Special emphasis is placed on the clinical data, genetic models, and the effects of ADDs on NCAM/PSA-NCAM expression in the brain regions in which these proteins are constitutively expressed and neurogenesis is not a major factor; this emphasis is necessary to prevent cell proliferation and neurogenesis from obscuring the issue of brain plasticity.

Abstract
OBJECTIVE Antidepressants Modulate Neuronal Plasticity. Tianeptine, An Atypical Antidepressant, Might Be Involved In The Restoration Of Neuronal Plasticity; It Primarily Enhances The Synaptic Reuptake Of Serotonin. Ncam140 Is Involved In Neuronal Development Processes, Synaptogenesis And Synaptic Plasticity. We Investigated The Effect Of Tianeptine On The Expression Of Ncam140 And Its Downstream Signaling Molecule In The Human Neuroblastoma Cell Line Sh-sy5y. METHODS NCAM protein expression was measured in human neuroblastoma SH-SY5Y cells that were cultivated in serum-free media and treated with 0, 10, or 20 µM tianeptine for 6, 24, or 72 hours. NCAM140 expression in the tianeptine treatment group was confirmed by Western blot, and quantified through measurement of band intensity by absorbance. CREB and pCREB expression was identified after treatment with 20 µM tianeptine for 6, 24, and 72 hours by Western blot. RESULTS Compared to cells treated for 6 hours, cells treated with 0 or 10 µM tianeptine for 72 hours showed a significant increase in NCAM140 expression and cells treated with 20 µM tianeptine showed a significant increase after 24 and 72 hours. The pCREB level in cells treated with 20 µM tianeptine increased in time-dependent manner. CONCLUSION Our findings indicated that the tianeptine antidepressant effect may occur by induction of NCAM140 expression and CREB phosphorylation.

[PMID: 24270379 DOI: 10.3892/mmr.2013.1823] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2013] [Accepted: 11/08/2013] [Indexed: 11/05/2022] Open
Abstract
The aim of this study was to investigate the effects of donepezil hydrochloride (DH) on the expression of the calpain I-cyclin-dependent kinase5/p25 (CDK5/p25) pathway in the hippocampal CA1 region in mice with cerebral ischemia-reperfusion (I/R). Mice were randomly divided and assigned to the sham operation group (SO), the model group (MG) and the DH treatment group (TG). The pathological appearance of the hippocampal CA1 region and the expression of calpain I and CDK5/p25, were observed on the 4th, 6th and 8th week of the I/R surgery. Within the same time periods, superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were also determined. At each postoperative time point, the normal neuron count in the hippocampal CA1 region in the MG was significantly lower than that in the SO (P<0.05), whereas the calpain I and CDK5/p25 expression, SOD activity and MDA content in the MG were significantly higher than those in the SO (P<0.05). The normal neuron count of the hippocampal CA1 region in the TG increased significantly (P<0.05), whereas the calpain I and CDK5/p25 expression, SOD activity and MDA content in the TG were significantly lower than those in the MG (P<0.05). DH has protective effects against ischemic damage. The ability of DH to improve learning and memory in mice may be due to its ability to decrease the expression of the calpain I-CDK5/p25 pathway and reduce oxidative damage.

Choi MR, Oh DH, Kim SH, Jung KH, Das ND, Chai YG. Fluoxetine increases the expression of NCAM140 and pCREB in rat C6 glioma cells. Psychiatry Investig 2012; 9:180-6. [PMID: 22707970 PMCID: PMC3372567 DOI: 10.4306/pi.2012.9.2.180] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2011] [Revised: 06/11/2011] [Accepted: 07/27/2011] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE Dysfunction of neural plasticity in the brain is known to alter neural networks, resulting in depression. To understand how fluoxetine regulates molecules involved in neural plasticity, the expression levels of NCAM, NCAM140, CREB and pCREB, in rat C6 glioma cells after fluoxetine treatment were examined. METHODS C6 cells were cultured after 20 min or after 6, 24 or 72 h treatments with 10 µM fluoxetine. Immunocytochemistry was used to determine the effect of fluoxetine on the expression of NCAM. Western blot analysis was used to measure the expression levels of NCAM140 and CREB and the induction of pCREB after fluoxetine treatment. RESULTS NCAM expression following 72-h fluoxetine treatment was significantly increased around cell membranes compared to control cells. Cells treated with fluoxetine for 6 and 72 h showed a significant increase in NCAM140 expression compared to cells treated for 20 min. The level of pCREB in the cells treated with fluoxetine for 72 h not only increased more than 60%, but was also significantly different when compared with the other treatment times. The 72-h fluoxetine treatment led to the increase of NCAM140 and the phosphorylation of CREB in C6 cells. CONCLUSION Our findings indicate that fluoxetine treatment regulates neuronal plasticity and neurite outgrowth by phosphorylating and activating CREB via the NCAM140 homophilic interaction-induced activation of the Ras-MAPK pathway.
