Abstract
Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine secreted by the pineal gland during the dark phase of the photoperiod. Its main function is the synchronization of different body rhythms with the dark-light cycle. Research on melatonin has significantly advanced since its discovery and we now know that it has considerable significance in various physiological processes, including immunity, aging, and reproduction. Moreover, in recent years evidence of the pharmacological possibilities of melatonin has increased. Indoleamine, on the other hand, has antidepressant-like effects in rodents, which may be mediated by the activation of calcium-calmodulin-dependent kinase II (CaMKII) and are also related to the regulation of neuroplasticity processes, including neurogenesis, synaptic maintenance, and long-term potentiation. Remarkably, patients with major depression show decreased levels of circulating melatonin in plasma. This review presents evidence of the antidepressant-like effects of melatonin in preclinical models and the participation of CaMKII in these actions. CaMKII's role in cognition and memory processes, which are altered in depressive states, are part of the review, and the effects of melatonin in these processes are also reviewed. Furthermore, participation of CaMKII on structural and synaptic plasticity and the effects of melatonin are also described. Finally, the advantages of using melatonin in combination with other antidepressants such as ketamine for neuroplasticity are described. Evidence supports that CaMKII is activated by melatonin and downstream melatonin receptors and may be the common effector in the synergistic effects of melatonin with other antidepressants. SIGNIFICANCE STATEMENT: This review compiled evidence supporting that melatonin causes antidepressant-like effects in mice through calmodulin kinase II stimulation of downstream melatonin receptors as well as the participation of this enzyme in neuroplasticity, memory, and cognition. Finally, we describe evidence about the effectiveness of antidepressant-like effects of melatonin in combination with ketamine.

Neuregulin-1/PI3K signaling effects on oligodendrocyte proliferation, remyelination and behaviors deficit in a male mouse model of ischemic stroke. Exp Neurol 2023; 362:114323. [PMID: 36690057 DOI: 10.1016/j.expneurol.2023.114323] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 01/12/2023] [Accepted: 01/13/2023] [Indexed: 01/22/2023]
Abstract
In this study, we investigated the effect of neuregulin-1 (NRG1) on demyelination and neurological function in an ischemic stroke model, and further explored its neuroprotective mechanisms. Adult male ICR mice underwent photothrombotic ischemia surgery and were injected with NRG1 beginning 30 min after ischemia. Cylinder and grid walking tests were performed to evaluate the forepaw function. In addition, the effect of NRG1 on neuronal damage/death (Cresyl violet, CV), neuronal nuclei (NeuN), nestin, doublecortin (DCX), myelin basic protein (MBP), non-phosphorylated neurofilaments (SMI-32), adenomatous polyposis coli (APC), erythroblastic leukemia viral oncogene homolog (ErbB) 2, 4 and serine-threonine protein kinase (Akt) in cortex were evaluated using immunohistochemistry, immunofluorescence and western blot. The cylinder and grid walking tests exposed that treatment of NRG1 observably regained the forepaw function. NRG1 treatment reduced cerebral infarction, restored forepaw function, promoted proliferation and differentiation of neuron and increased oligodendrogliogenesis. The neuroprotective effect of NRG1 is involved in its activation of PI3K/Akt signaling pathway via ErbB2, as shown by the suppression of the effect of NRG1 by the PI3K inhibitor LY294002. Our results demonstrate that NRG1 is effective in ameliorating the both acute phase neuroprotection and long-term neurological functions via resumption of neuronal proliferation and differentiation and oligodendrogliogenesis in a male mouse model of ischemic stroke.

Abstract
According to modern view, susceptibility to diseases, specifically to cognitive and neuropsychiatric disorders, can form during embryonic development. Adverse factors affecting mother during the pregnancy increase the risk of developing pathologies. Despite the association between elevated maternal blood homocysteine (Hcy) and fetal brain impairments, as well as cognitive deficits in the offspring, the role of brain plasticity in the development of these pathologies remains poorly studied. Here, we review the data on the negative impact of hyperhomocysteinemia (HHcy) on the neural plasticity, in particular, its possible influence on the offspring brain plasticity through epigenetic mechanisms, such as changes in intracellular methylation potential, activity of DNA methyltransferases, DNA methylation, histone modifications, and microRNA expression in brain cells. Since placenta plays a key role in the transport of nutrients and transmission of signals from mother to fetus, its dysfunction due to aberrant epigenetic regulation can affect the development of fetal CNS. The review also presents the data on the impact of maternal HHcy on the epigenetic regulation in the placenta. The data presented in the review are not only interesting from purely scientific point of view, but can help in understanding the role of HHcy and epigenetic mechanisms in the pathogenesis of diseases, such as pregnancy pathologies resulting in the delayed development of fetal brain, cognitive impairments in the offspring during childhood, and neuropsychiatric and neurodegenerative disorders later in life, as well as in the search for approaches for their prevention using neuroprotectors.

Abstract
Melatonin has been reported to affect intestinal function by targeting microbiome, morphological structure, barrier integrity and nutrient absorptive system. While the effect of melatonin on intestinal development in newborn infants is obscure, thus, this study firstly attempted to investigate the hypothesis that melatonin treatment improves intestinal development in sucking piglets. 14 healthy newborn piglets received 10 ml melatonin solution (1 mg/ml) or drinking water (n = 7) for 21 days. The results showed that oral administration of melatonin increased liver relative weight (p < 0.05) but failed to affect growth performance in sucking piglets (p > 0.05). Immunostaining jejunal samples from melatonin group showed high expressions of nnos and claudin1, indicating that melatonin improved intestinal neural development and barrier integrity. Also, melatonin promoted intestinal absorptive function evidenced by the increased serum proline concentration in melatonin-treated piglets compared with the control (p < 0.05). Gut microbiota compositions were tested by 16S rDNA sequencing and the results showed that melatonin increased the relative abundance of Actinobacteria compared with the control (p < 0.05) at the phylum level. However, Selenomonadales was markedly reduced compared with the control at the order level (p < 0.05). Gut and faecal volatile fatty acids were tested to evaluate the microbiota metabolism, but no difference was noticed in volatile fatty acid concentrations (p > 0.05). Melatonin improved intestinal development by affecting neural development, barrier integrity, nutrient absorption and microbiota in sucking piglets.

Abstract
It is well known that aging induces a progressive decline in the proliferation and neural differentiation of radial glial cells (RGCs) in the hippocampal dentate gyrus (DG). The function of miR-144/451 is to activate stress-regulated molecular gene expression switches for cell proliferation and differentiation. We found that the miR-144/451 expression in the hippocampus was significantly reduced in aged mice compared to adult mice. Furthermore, the proliferation and neural differentiation of RGCs in the mouse hippocampal DG was decreased by miR-144/451 knockout (miR-144/451-/-). Antioxidant agents, superoxide dismutases (SODs) and catalase, and the expression of melatonin's receptor in the hippocampus were decreased in the miR-144/451-/- mice. In addition, the (protein kinase B) AKT/(glycogen synthase kinase 3β) GSK3β/(catenin beta-1) β-catenin signaling pathway was weakly activated in the hippocampus of miR-144/451-/- mice, which was related to brain neurogenesis. Melatonin treatment improved the expression of miR-144/451 and antioxidant enzymes and activated the AKT/GSK3β/β-catenin pathway in the hippocampus of miR-144/451-/- mice. When the AKT pathway was inhibited by LY294002, the neurogenerative and antioxidant effects of melatonin were significantly limited in the hippocampus of miR-144/451-/- mice. In brief, our results indicated that miR-144/451 plays crucial roles in the proliferation and neural differentiation of RGCs via the regulation of the antioxidant and AKT/GSK3β/β-catenin pathways.

Abstract
Domestic pigs have become increasingly popular as a model for human diseases such as neurological diseases. Drug discovery platforms have increasingly been used to identify novel compounds that combat neurodegeneration. Currently, bioactive molecules such as melatonin have been demonstrated to offer a neuroprotective effect in several studies. However, a neurodegenerative platform to study novel compounds in a porcine model has not been fully established. In this study, characterized porcine induced neural stem cells (iNSCs) were used for evaluation of the protective effect of melatonin against chemical and pathogenic stimulation. First, the effects of different concentrations of melatonin on the proliferation of porcine iNSCs were studied. Second, porcine iNSCs were treated with the appropriate concentration of melatonin prior to induced degeneration with dimethyl sulfoxide or Zika virus (ZIKV). The results demonstrated that the percentages of Ki67 expression in porcine iNSCs cultured in 0.1, 1, and 10 nM melatonin were not significantly different from that in the control groups. Melatonin at 1 nM protected porcine iNSCs from DMSO-induced degeneration, as confirmed by a dead cell exclusion assay and mitochondrial membrane potential (ΔΨm) analysis. In addition, pretreatment with melatonin reduced the percentage of dead porcine iNSCs after ZIKV infection. Melatonin increased the ΔΨm, resulting in a decrease in cell degeneration. However, pretreatment with melatonin was unable to suppress ZIKV replication in porcine iNSCs. In conclusion, the present study demonstrated the anti-degenerative effect of melatonin against DMSO- and ZIKV-induced degeneration in porcine iNSCs.

Abstract
Melatonin (MLT), a pineal neurohormone with multiple neuroprotective, is often used for peripheral nerve recovery and regenerated nerve proliferation. In this study, Polycaprolactone/Gelatin (PG) fibrous electrospun scaffolds with various percentages of MLT (0, 1, 2, and 4%wt) were fabricated for nerve cell growth, the effects of different concentrations of MLT within PG fibers (PG, PGMLT1, PGMLT2, and PGMLT4) on the proliferation and differentiation for PC12 cells were quantitatively evaluated. The microstructures and morphologies of these scaffolds were analyzed by FE-SEM and digital camera. Fourier transform infrared spectrometer (FTIR), X-ray photoelectron spectroscopy (XPS), and Water Contact Angle (WCA) were used to study the composition, ratio and properties of MLT functionalized PG scaffolds. MTT and CLSM analysis showed that appropriate amount of MLT was beneficial to the proliferation of PC12 cell. MLT can also promote cell differentiation, neurite germination, the expression levels of MAP2 mRNA and protein were dramatically increased on the composite scaffolds with the increase of MLT content, moderate addition of MLT (PGMLT2, 2%) had a prominent enhancement for neurite length. This work would provide a more comprehensive reference for further researches on MLT functionalized composite scaffolds and suggest that high-performance PGMLT fibrous scaffolds could be a promising alternative for nerve repair.

Melatonin Attenuates Ropivacaine-Induced Apoptosis by Inhibiting Excessive Mitophagy Through the Parkin/PINK1 Pathway in PC12 and HT22 Cells. Inflammation 2022; 45:725-738. [PMID: 34994877 DOI: 10.1007/s10753-021-01579-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 10/07/2021] [Indexed: 11/05/2022]
Abstract
Melatonin, as an endogenous circadian indoleamine secreted by the pineal gland, executes extensive biological functions, including antioxidant, anti-inflammatory, anti-tumor, and neuroprotective effects. Although melatonin has been reported to serve as a potential therapeutic against many nerve injury diseases, its effect on ropivacaine-induced neurotoxicity remains obscure. Our research aimed to explore the impact and mechanism of melatonin on ropivacaine-induced neurotoxicity. Our results showed that melatonin pretreatment protected the cell viability, morphology, and apoptosis of PC12 and HT22 cells, and it also improved ropivacaine-induced mitochondrial dysfunction and the activation of mitophagy. In addition, we found that autophagy activation with rapamycin significantly weakened the protective effect of melatonin against ropivacaine-induced apoptosis, whereas autophagy inhibition with 3-MA enhanced the effect of melatonin. We also detected the activation of Parkin and PINK1, a canonical mechanism for mitophagy regulation, and results shown that melatonin downregulated the expression of Parkin and PINK1, and upregulated Tomm20 and COXIV proteins, so that those results indicated that melatonin protected ropivacaine-induced apoptosis through suppressing excessive mitophagy by inhibiting the Parkin/PINK1 pathway. Melatonin may be a useful potential therapeutic agent against ropivacaine-induced neurotoxicity.

Abstract
OBJECTIVE To explore the effect of melatonin (MT) on 2, 2', 4, 4'-tetrabromodiphenylether (PBDE-47)-induced abnormal autophagy and apoptosis in rat adrenal medullary pheochromocytoma PC12 cells. METHODS PC12 cells were pretreated with a concentration gradient (12.5, 25, 50, 100, and 200 μmol/L) of melatonin for 2 h before exposure to 20 μmol/L PBDE-47 for 24 h to determine the optimal concentration of melatonin for cell treatment. In subsequent experiments, PC12 cells were treated with 0.5‰ DMSO (control group), 20 μmol/L PBDE-47, 25 μmol/L melatonin, or both PBDE-47 and melatonin. Immunofluorescence assay was used to detect the positive staining of microtubule associated protein 1 light chain 3 (LC3; a marker protein of autophagy); Western blotting was performed to determine the expression levels of the key autophagic proteins including autophagy-related protein 7 (ATG7), LC3-Ⅱ and autophagy substrate p62, and the key apoptotic proteins including active cysteine-containing aspartate specific protease-3 (active caspase-3) and cleaved poly(ADP ribose) polymerase (cleaved PARP). RESULTS PBDE-47 treatment significantly reduced the viability of PC12 cells (P=0.001), but pretreatment with 25 μmol/L melatonin maintained a cell viability over 80% following exposure to PBDE-47 (P=0.023). PBDE-47-treated PC12 cells showed obviously enhanced immunofluorescent staining of LC3 protein, a significantly decreased expression of ATG7 and increased expression levels of p62, LC3-Ⅱ, active caspase-3 and cleaved PARP (P < 0.001). The cells treated with both PBDE-47 and melatonin showed obviously reduced staining of LC3 protein with a signficantly increased expression level of ATG7 (P=0.034) and decreased expressions of p62 (P=0.048), LC3-Ⅱ (P=0.018), active caspase-3 (P < 0.001) and cleaved PARP (P=0.032). CONCLUSION PBDE-47 exposure impairs autophagy to cause autophagosome accumulation and promote apoptosis of PC12 cells. Melatonin can improve PBDE-47-induced abnormal autophagy and apoptosis and thus promote the survival of PC12 cells.

Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disorder affecting elderly people (>60 years old) worldwide. There is no permanent cure for the disease but the symptomatic relief can be obtained by using dopamine agonists besides L-dopa therapy. The longer use of the drugs is associated with several side effects. Hence, the researchers have made a considerable attention toward the development of neuroprotective agents from plants. A number of phytochemicals have been demonstrated for their protective effects in various in vitro, in vivo, and clinical studies. In this context, luteolin, a flavone which is present in fruits and vegetables has been attributed to a number of pharmacological properties including neuroprotective. The present review demonstrates the bioavailability, oral absorption, and mechanism of action against PD.

Abstract
Alzheimer’s disease (AD) is a common chronic neurodegenerative disorders. Melatonin (MLT) has been reported to be neuroprotective agent, and its modified structures exhibit potent antioxidant and anti-inflammation activities. Therefore, the activity of MLT and its derivatives against AD was investigated. Herein, the targeted enzymes, such as β-secretase (BACE1) and acetylcholinesterase (AChE), as well as the neuroprotective and neuritogenic effects on P19-derived neurons were evaluated. All the derivatives (1–5), including MLT, displayed potent inhibitory activity for BACE1, with inhibition values of more than 75% at 5 µM. A molecular docking study predicted that MLT, 5-MT, and 5 bound with BACE1 at catalytic amino acids Asp32 and the flap region, whereas 1–4 interacted with allosteric residue Thr232 and the flap region. The additional π-π interactions between 2, 3, and 5 with Tyr71 promoted ligand-enzyme binding. In addition, MLT, 1, 3, and 5 significantly protected neuron cells from oxidative stress by increasing the cell viability to 97.95, 74.29, 70.80, and 69.50% at 1 nM, respectively. Moreover, these derivatives significantly induced neurite outgrowth by increasing the neurite length and number. The derivatives 1, 3, and 5 should be thoroughly studied as potential AD treatment and neuroprotective agents.

Abstract
Neurogenesis is the process by which functional new neurons are generated from the neural stem cells (NSCs) or neural progenitor cells (NPCs). Increasing lines of evidence show that neurogenesis impairment is involved in different neurological illnesses, including mood disorders, neurogenerative diseases, and central nervous system (CNS) injuries. Since reversing neurogenesis impairment was found to improve neurological outcomes in the pathological conditions, it is speculated that modulating neurogenesis is a potential therapeutic strategy for neurological diseases. Among different modulators of neurogenesis, melatonin is a particularly interesting one. In traditional understanding, melatonin controls the circadian rhythm and sleep-wake cycle, although it is not directly involved in the proliferation and survival of neurons. In the last decade, it was reported that melatonin plays an important role in the regulation of neurogenesis, and thus it may be a potential treatment for neurogenesis-related disorders. The present review aims to summarize and discuss the recent findings regarding the protective effects of melatonin on the neurogenesis impairment in different neurological conditions. We also address the molecular mechanisms involved in the actions of melatonin in neurogenesis modulation.

Abstract
Neuronal plasticity describes changes in structure, function, and connections of neurons. The hippocampus, in particular, has been shown to exhibit considerable plasticity regarding both physiological and morphological functions. Melatonin, a hormone released by the pineal gland, promotes cell survival and dendrite maturation of neurons in the newborn brain and protects against neurological disorders. In this study, we investigated the effect of exogenous melatonin on neuronal architecture and its possible mechanism in the hippocampus of adult male C57BL/6 mice. Melatonin treatment significantly increased the total length and complexity of dendrites in the apical and basal cornu ammonis (CA) 1 and in the dentate gyrus in mouse hippocampi. Spine density in CA1 apical dendrites was increased, but no significant differences in other subregions were observed. In primary cultured hippocampal neurons, the length and arborization of neurites were significantly augmented by melatonin treatment. Additionally, western blot and immunohistochemical analyses in both in vivo and in vitro systems revealed significant increases in the level of cysteine-rich protein 1 (crp-1) protein, which is known to be involved in dendritic branching in mouse hippocampal neurons after melatonin treatment. Our results suggest that exogenous melatonin leads to significant alterations of neuronal micromorphometry in the adult hippocampus, possibly via crp-1 signaling.

Abstract
Background/purpose Melatonin, at physiological concentrations, was previously found to inhibit proliferation and promote odontogenic differentiation in human dental pulp cells (hDPCs), but its effect on apoptosis is unclear. Our study aimed to investigate the effect of melatonin on the H2O2-mediated viability reduction and apoptosis in hDPCs. Materials and methods hDPCs were treated with H2O2 (0, 250, 500, 1000 μmol/L), melatonin (0, 10−12, 10−10, 10−8 mol/L), and melatonin with H2O2 for 24 h. CCK-8 assays were performed to evaluate cell viability. Apoptosis was measured by DAPI and Annexin V/propidium iodide staining. Intracellular reactive oxygen species (ROS) were measured by CellROX® staining and mitochondrial membrane potential (ΔΨm) was examined by JC-1 staining. Results H2O2 obviously decreased the viability of hDPCs in a concentration-dependent manner and melatonin alone also reduced viability by 16–20%. Melatonin was also found to enhance H2O2-induced toxicity in a concentration-dependent manner, and the highest physiological concentration of melatonin (10−8 mol/L) had the most obvious effect (P < 0.001). Treating H2O2-exposed hDPCs with melatonin significantly increased the ratio of apoptotic cells with condensed and deformed nuclei (P < 0.001), as well as the percentage of Annexin V-positive cells (P < 0.01). Furthermore, melatonin significantly increased intracellular ROS levels and induced the loss of ΔΨm in H2O2-exposed cells (P < 0.05). Conclusion Our results indicate that melatonin, at physiological concentrations, can enhance H2O2-induced apoptosis in hDPCs and increase H2O2-mediated ROS production and ΔΨm loss. Further studies are needed to investigate whether melatonin targets the mitochondrial death pathway during the process.

Abstract
The objective of the present work aimed to explore the potential of bacterial cellulose (BC) for oral delivery of melatonin (MLT), a natural hormone that faces problems of low solubility and oral bioavailability. BC was hydrolyzed by sulfuric acid followed by the oxidation to prepare bacterial cellulose nanofiber suspension (BCNs). Melatonin-loaded bacterial cellulose nanofiber suspension (MLT-BCNs) was prepared by emulsion solvent evaporation method. The properties of freeze-dried BCs and MLT-BCNs were studied by Fluorescence microscopy (FM), scanning electron microscopy (SEM), Fourier-transform infrared (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and thermo gravimetric (TG). The results indicated that the fibers in BCNs became short and thin compared with BC, MLT in MLT-BCNs was uniformly distributed, both BCNs and MLT-BCNs have good thermodynamic stability. The MLT-BCNs showed more rapid dissolution MLT rates compared to the commercially available MLT in SGF and SIF, the dissolution of the cumulative release rate was about 2.1 times of the commercially available MLT. The oral bioavailability of MLT-BCNs in rat was about 2.4 times higher than the commercially available MLT. Thus, MLT-BCNs could act as promising delivery with enhanced dissolution and bioavailability for MLT after oral administration.

Abstract
Melatonin, a highly lipophilic molecule secreted by the pineal gland in the brain, plays a role in various biological functions. Previous studies reported that melatonin exerts its effect on mesenchymal stem cell (MSC) survival and differentiation into osteogenic- and adipogenic-lineage. However, the effect of melatonin in neurogenic differentiation in amniotic fluid (AF)-MSCs remains to be explored, thus we investigated the potential role of melatonin on dopaminergic neuron differentiation in AF-MSCs. The results showed that various concentrations of melatonin did not affect cell viability and proliferative effects of AF-MSCs. Increases in the levels of neuronal protein marker (βIII-tubulin) and dopaminergic neuronal markers (tyrosine hydroxylase, TH and NURR1), but decrease in the level of glial fibrillary acidic protein (GFAP), were observed in melatonin-treated AF-MSCs. Melatonin induced alteration in differential expression patterns of mesenchymal stem cell antigens by reducing CD29, CD45, CD73, CD90 and CD105, but no changing CD34 expressing cells. AF-MSCs were sequentially induced in neurobasal medium containing standard inducing cocktails (ST: bFGF, SHH, FGF8, BDNF), 1 μM melatonin, or a combination of ST and melatonin. The levels of TUJ1, TH, MAP2, NURR1 and dopamine transporter (DAT) were significantly increased in all treated groups when compared with control-untreated cells. Pretreated AF-MSCs with non-selective MT1/MT2 receptors antagonist, luzindole and selective MT2 receptor antagonist, 4-P-PDOT diminished melatonin-induced increase in dopaminergic neuronal markers and phosphorylated ERK but did not diminish increase in phosphorylated CaMKII by melatonin. Pretreatment with mitogen-activated protein kinase (MEK) inhibitor, PD98059 and CaMKII inhibitor, KN-93 were able to abolish increase in the levels of dopaminergic markers in melatonin-treated AF-MSCs. These findings suggest that melatonin promotes dopaminergic neuronal differentiation of AF-MSCs possibly via the induction in ERK and CaMKII pathways through melatonin receptor-dependent and -independent mechanisms, respectively.

Abstract
Previous studies have shown that the sciatic nerve has neurotrophic activity, and nerve regeneration, differentiation, and axon outgrowth can be modulated by different sciatic nerve preparations. However, numerous animals may have to be sacrificed to obtain enough sciatic nerves to make a sciatic nerve preparation. Some studies have demonstrated that the role of sciatic nerve preparations in neural differentiation depends on the neurotrophins that Schwann cells secrete, and these factors are highly conserved among different species. To reduce the use of experimental animals, in this study, we made a leachate by using the sciatic nerve of cattle and explored its effect on neuronal differentiation of rat PC12 cells (a useful model for studying neuronal differentiation). Results showed the neurite outgrowth of PC12 cells treated with the cattle sciatic nerve leachate for 3, 6, and 9 days was significantly improved, and the expressions of β3-tubulin and microtubule-associated protein 2 (two neuron-specific proteins) were increased. Moreover, the ERK1/2 signaling pathway was activated after PC12 cells were incubated with cattle sciatic nerve leachate for 9 days. Thus, a sciatic nerve leachate obtained from cattle can effectively induce neuronal differentiation of rat PC12 cells via ERK1/2 signaling pathway.

Abstract
New in vitro studies have demonstrated that N-acetyl-5-methoxytryptamine (Melatonin) has cytotoxic and apoptotic effects on various cell types although most of the previous investigations document that it is a potent antioxidant. However, the precise molecular mechanism(s) of its effects are not fully elucidated. In this study, we examined dose-dependent cytotoxic, genotoxic, apoptotic and reactive oxygen species (ROS) generating effects of melatonin in human epidermoid carcinoma cells (A-431) and human normal skin fibroblastic cells (CCD-1079Sk). The cells were incubated with different doses of melatonin (0.031-5 mM) for 24 h. Cell viability was assessed based on luminometric ATP cell viability assay. Intracellular ROS was detected using 2,7-dichlorodihydrofluorescein-diacetate (H2DCF-DA) fluorescent probes. Genotoxicity was evaluated by alkaline single cell gel electrophoresis assay (Comet Assay). Apoptosis was evaluated by western blotting, DAPI staining, acridine orange/ethidium bromide and Annexin V-FITC/propidium iodide double staining methods Mitochondrial membrane potentials were measured by flow cytometry. Although lower doses of melatonin (0.031-0.06 mM) increased cell proliferation and decreased ROS generation, higher doses (0.125-5 mM) markedly inhibited the cell viability, induced DNA damage, apoptosis and ROS generation. Cytotoxic, genotoxic, apoptotic and ROS generating effects were significantly higher in cancer cells than those observed in normal cells. Melatonin-induced cell death, and ROS generating activity were effectively inhibited by N-acetyl-l-cysteine (NAC) In conclusion, at low doses, melatonin has proliferative effects on both cancer and normal cells, whereas high concentrations have cytotoxic effects. Cytotoxic, genotoxic and apoptotic effects at higher doses of melatonin may be due to its ROS production capacity.

Chen L, Ning H, Yin Z, Song X, Feng Y, Qin H, Li Y, Wang J, Ge Y, Wang W. The effects of fluoride on neuronal function occurs via cytoskeleton damage and decreased signal transmission. CHEMOSPHERE 2017; 185:589-594. [PMID: 28719878 DOI: 10.1016/j.chemosphere.2017.06.128] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2017] [Revised: 06/28/2017] [Accepted: 06/29/2017] [Indexed: 06/07/2023]
Abstract
It has been reported that fluoride exposure may cause serious public health problems, particularly neurotoxicity. However, the underlying mechanisms remain unclear. This study used Neuro-2A cells to investigate the effects of fluoride on the cytoskeleton. The Neuro-2A cells were exposed to 0, 1, 2, 4 and 6 mM sodium fluoride (NaF) for 24 h. Cell viability and lactate dehydrogenase (LDH) release were examined. It was observed that exposure to NaF reduced cell viability, disrupted cellular membrane integrity, and high levels of LDH were released. The observed changes occurred in a dose response manner. Morphologic observations showed that cell became rounded and were loosely adherent following exposure to NaF. Axon spines and normal features disappeared with high dose NaF treatment. The expression of MAP2 and synaptophysin decreased, particularly at 4 mM and 6 mM (P < 0.05) for MAP2. These results corroborate the morphologic observations. The content of glutamate and NMDAR (glutamate receptor) protein were assessed to help understand the relationship between synapses and neurotransmitter release using ELISA and Western-blot. Compared with the control, glutamate and NMDAR expression declined significantly at 4 mM and 6 mM (P < 0.05) group. Finally, the ultrastructural changes observed with increasing doses of NaF were: disappearance of synapses, mitochondrial agglutination, vacuole formation, and cellular edema. Taken together, NaF exposure disrupted cellular integrity and suppressed the release of neurotransmitters, thus effecting neuronal function. These findings provide deeper insights into roles of NaF in neuron damage, which could contribute to a better understanding of fluoride-induced neurotoxicity.

The acute exposure of tetrachloro-p-benzoquinone (a.k.a. chloranil) triggers inflammation and neurological dysfunction via Toll-like receptor 4 signaling: The protective role of melatonin preconditioning. Toxicology 2017; 381:39-50. [PMID: 28238930 DOI: 10.1016/j.tox.2017.02.015] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2016] [Revised: 02/22/2017] [Accepted: 02/22/2017] [Indexed: 02/06/2023]
Abstract
This study is aimed to investigate the inflammation and neurological dysfunction induced by tetrachloro-p-benzoquinone (TCBQ) through Toll-like receptor 4 (TLR4) signaling. We also investigated the protective role of melatonin as an antioxidant and anti-inflammatory agent. In vitro model was established by rat pheochromocytoma PC12 cells, meanwhile, TLR4 wild-type (C57BL/6) and knockout mice (C57BL/10ScNJ TLR4-/-) were used as in vivo model. In vitro study showed TCBQ exposure enhanced the expression of TLR4, myeloid differentiation factor 88 (MyD88) at both transcriptional and post-transcriptional levels. By contrast, melatonin decreased TLR4 and MyD88 expressions. Moreover, our result indicated that melatonin disrupted the formation of TLR4/MyD88/MD2/CD14 complex. In addition, melatonin terminated TCBQ-mediated phosphorylation of c-Jun N-terminal kinase (JNK), p38, and extracellular regulated protein kinase (ERK) signaling and hampered its downstream pro-inflammatory cytokine releases. In vivo result also indicated TLR4 deficiency partially protected against TCBQ-induced morphological and neuropathological changes in mice brain, suggested the role of TLR4. In conclusion, melatonin modulates TCBQ-mediated inflammatory genes through TLR4/MyD88-dependent signaling pathway. Our current study, to the best of our knowledge, is the first time show melatonin not only disrupt the binding of TLR4 and MyD88, but also restricted the formation of TLR4/MD2/CD14 complex, suggesting that melatonin supplementary may represent a valuable therapeutic strategy for inflammatory neurological dysfunction.

Abstract
Treatment of prostate cancer (PCa), a leading cause of cancer among males, lacks successful strategies especially in advanced, hormone-refractory stages. Some clinical studies have shown an increase in neuroendocrine-like cells parallel to the tumor progression but their exact role is a matter of debate. The prostate is a well-known target for melatonin, which reduces PCa cells proliferation and induces neuroendocrine differentiation. To evaluate the mechanisms underlying the indole effects on neuroendocrine differentiation and its impact on PCa progression, we used a cell culture model (LNCaP) and a murine model (TRAMP). Persistent ERK1/2 activation was found in both, melatonin and androgen-deprived cells. Melatonin blocked nuclear translocation of androgen receptor (AR), thus confirming anti-androgenic actions of the indole. However, using a comparative genome microarray to check the differentially expressed genes in control, melatonin, or androgen-deprived cells, some differences were found, suggesting a more complex role of the indole. By comparing control cells with those treated with melatonin or depleted of androgen, a cluster of 26 differentially expressed genes (±2.5-fold) was found. Kallikreins (KLK)2 and KLK3 (PSA) were dramatically downregulated by both treatments whereas IGFBP3 and IGF1R were up- and downregulated, respectively, in both experimental groups, thus showing a role for IGF in both scenarios. Finally, melatonin prolonged the survival of TRAMP mice by 33% when given at the beginning or at advances stages of the tumor. Serum IGFBP3 was significantly elevated by the indole in early stages of the tumor, confirming in vivo the role of the IGF signaling in the oncostatic action of the indole.
