Behavioral and Molecular Analysis of Antioxidative Potential of Rosmarinic Acid Against Methamphetamine-induced Augmentation of Casp3a mRNA in the Zebrafish Brain. Basic Clin Neurosci 2021; 12:243-254. [PMID: 34925721 PMCID: PMC8672665 DOI: 10.32598/bcn.12.2.1777.1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 05/14/2020] [Accepted: 12/01/2020] [Indexed: 11/21/2022] Open
Abstract
Introduction: Methamphetamine (MA) acts as a powerful oxidant agent, while Rosmarinic Acid (RA) is an effective herbal antioxidant. Oxidative stress-mediated by MA results in apoptosis, and caspase-3 is one of the critical enzymes in the apoptosis process. MA can epigenetically alter gene regulation. In this paper, to investigate the effects of RA on MA-mediated oxidative stress, changes in the level of casp3a mRNA were demonstrated in zebrafish. Methods: The animals were grouped in 3 treatment conditions for the behavioral test: control, MA, MA pretreated by RA, and 6 treatment conditions for the molecular test: control, RA, MA, MA co-treated with RA, MA co-treated with RA/ZnO/chitosan nanoparticle, and ZnO/chitosan nanoparticle. Then molecular and behavioral investigations were carried out, and critical comparisons were made between the groups. MA solution was prepared with a concentration of 25 mg/L, and RA solution was prepared by DPPH test with the antioxidant power of about 97%. Each solution was administered by immersing 20 zebrafish for 20 minutes, once per day for 7 days. The level of casp3a mRNA was quantified by using qRT-PCR. One-sided trapezoidal tank diving test was applied to study behavioral alterations. Results: The qPCR analysis demonstrated the high potential of RA/ZnO/chitosan in counteracting the MA-mediated elevation in casp3a mRNA level. Based on the diving test results of MA-treated fish, MA was found to be anxiolytic compared to the control. While the resulted diving pattern of the MA-treated animals pretreated by RA was novel and different from both the control and MA-treated groups. Conclusion: The potential of RA combined with a suitable nanoparticle against MA-induced oxidative stress was supported. The high efficiency of ZnO/chitosan in increasing RA penetration to the brain cells was evident. MA at a dose of 25 mg/L is anxiolytic for zebrafish. However, the molecular mechanisms involved in these processes should be studied.

Melatonin ameliorates methamphetamine-induced cognitive impairments by inhibiting neuroinflammation via suppression of the TLR4/MyD88/NFκB signaling pathway in the mouse hippocampus. Prog Neuropsychopharmacol Biol Psychiatry 2021; 111:110109.

Abstract
Methamphetamine (METH) is a highly addictive psychostimulant that causes significant health issues due to high prevalence of its illegal use. Chronic use of METH is associated with cognitive impairments in both human and animal studies, but the underlying mechanism remains unclear. METH-induced neuroinflammation is, potentially, one of the factors that causes cognitive impairments. Therefore, the present study aimed to assess whether melatonin could provide protection against inflammation, in a manner comparable to the anti-inflammatory agent, minocycline, with consequent improvements of METH-induced cognitive impairments and associated abnormalities in the mouse hippocampus. Results from the Morris water maze (MWM) test and the novel object recognition test (NORT) showed that melatonin given after METH injections could ameliorate both METH-induced spatial and recognition memory impairments. These memory impairments are associated with changes in the neuroinflammatory profiles, including IL-6, IL-1β, and TNF-α, both in the blood serum and hippocampus of adult mice. METH-treated mice also exhibited reactive astrocytes and activated microglia in the hippocampus. METH-induced activation of glial cells is associated with the activation of the TLR4/MyD88/NFκB signaling pathway. Moreover, melatonin administration led to recovery of these METH-induced markers to control levels. Thus, we conclude that melatonin could potentially be used as a cognitive enhancer and anti-inflammatory agent in the treatment of METH use disorder in humans.

Abstract
Methamphetamine (METH) is an illicit psychostimulant that is abused throughout the world. METH addiction is also a major public health concern and the abuse of large doses of the drug is often associated with serious neuropsychiatric consequences that may include agitation, anxiety, hallucinations, paranoia, and psychosis. Some human methamphetamine users can also suffer from attention, memory, and executive deficits. METH-associated neurological and psychiatric complications might be related, in part, to METH-induced neurotoxic effects. Those include altered dopaminergic and serotonergic functions, neuronal apoptosis, astrocytosis, and microgliosis. Here we have endeavored to discuss some of the main effects of the drug and have presented the evidence supporting certain of the molecular and cellular bases of METH neurotoxicity. The accumulated evidence suggests the involvement of transcription factors, activation of dealth pathways that emanate from mitochondria and endoplasmic reticulum (ER), and a role for neuroinflammatory mechanisms. Understanding the molecular processes involved in METH induced neurotoxicity should help in developing better therapeutic approaches that might also serve to attenuate or block the biological consequences of use of large doses of the drug by some humans who meet criteria for METH use disorder.

Abstract
Methamphetamine (METH) is an illegal amphetamine-typed psychostimulant that is abused worldwide and causes serious public health problems. METH exposure induces apoptosis and autophagy in neuronal cells. However, the role of pyroptosis in METH-induced neurotoxicity is still unclear. Here, we investigate whether pyroptosis is involved in METH-induced hippocampal neurotoxicity and the potential mechanisms of Endoplasmic reticulum (ER) stress in hippocampal neuronal cells. For this purpose, the expression levels of pyroptosis-related proteins, GSDMD and GSDME, were analyzed by immunoblotting and immunohistochemistry in the hippocampal neuron cell line HT-22. Next, we explored METH-induced pyroptosis in HT-22 using immunoblotting, LDH assays and SYTOX green acid staining. Further, the relationship between pyroptosis and ER stress in METH-induced hippocampal neuron damage was studied in HT-22 cells using inhibitors including TUDCA, a specific inhibitor of ER stress, GSK-2656157, a PERK pathway inhibitor and STF-0803010, an inhibitor of IRE1α endoribonuclease activity. This relationship was also studied using siRNAs, including siTRAF2, an siRNA against IRE1α kinase activity and siATF6 against the ATF6 pathway, which were analyzed by immunoblotting, LDH assays and SYTOX green acid staining. GSDME but not GSDMD was found to be expressed in HT-22 cells. METH treatment induced the upregulation of cleaved GSDME-NT and LDH release, as well as the increase of SYTOX green positive cells in HT-22 cells, which was partly reversed by inhibitors and siRNAs, indicating that the ER stress signaling pathway was involved in GSDME-dependent cell death induced by METH. In summary, these results revealed that METH induced ER stress that mediated GSDME-dependent cell death in hippocampal neuronal cells. These findings provide novel insight into the mechanisms of METH-induced neurotoxicity.

Mol Pharmacol 2019; 96:493-504. [PMID: 31409621 DOI: 10.1124/mol.119.116798] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Accepted: 08/02/2019] [Indexed: 12/30/2022] Open
Abstract
Methamphetamine (MA) is highly addictive and neurotoxic, causing cell death in humans and in rodent models. MA, along with many of its analogs, is an agonist at the G protein-coupled trace amine-associated receptor 1 (TAAR1). TAAR1 activation protects against MA-induced degeneration of dopaminergic neurons, suggesting that TAAR1 plays a role in regulating MA-induced neurotoxicity. However, the mechanisms involved in TAAR1's role in neurotoxicity and cell death have not been described in detail. In this study, we investigated the apoptosis pathway in Taar1 wild-type (WT) and knockout (KO) mice and in cells expressing the recombinant receptor. Bcl-2, an antiapoptotic protein, was upregulated ∼3-fold in the midbrain area (substantial nigra and ventral tegmental area) in Taar1 KO compared with WT mice, and MA significantly increased Bcl-2 expression in WT mice but decreased Bcl-2 expression in KO mice. The proapoptotic protein Bax did not differ across genotype or in response to MA. Bcl-2 expression was significantly upregulated by the TAAR1 agonist RO5166017 ((S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine) in cells expressing the recombinant mouse TAAR1. Additionally, activation of TAAR1 by RO5166017 increased phosphorylation of extracellular signal-regulated kinase (ERK) 1/2, and protein kinase B (AKT), but only inhibition of ERK1/2 phosphorylation prevented TAAR1-induced increases in Bcl-2 levels, indicating that TAAR1 activation increases Bcl-2 through an ERK1/2-dependent pathway. All changes to ERK1/2 pathway intermediates were blocked by the TAAR1 antagonist, N-(3-ethoxyphenyl)-4-(1-pyrrolidinyl)-3-(trifluoromethyl) benzamide. These findings suggest that TAAR1 activation protects against MA-induced cell apoptosis and TAAR1 may play a role in cell death in neurodegenerative diseases. SIGNIFICANCE STATEMENT: Methamphetamine stimulates TAAR1, a G protein-coupled receptor. The role and mechanisms for TAAR1 in methamphetamine-induced neurotoxicity are not known. Here, we report that, in genetic mouse models and cells expressing the recombinant receptor, TAAR1 activates the ERK1/2 pathway but not the AKT pathway to upregulate the antiapoptotic protein Bcl-2, which protects cells from drug-induced toxicity.

Abstract
Methamphetamine (METH) is a highly addictive stimulant, and METH exposure can induce irreversible neuronal damage and cause neuropsychiatric and cognitive disorders. The ever-increasing levels of METH abuse worldwide have necessitated the identification of effective intervention strategies to protect the brain against METH-induced neurotoxicity. The protective effects of molecular hydrogen on oxidative stress and related neurodegenerative diseases have been recently elucidated. Herein, we investigated whether treatment with molecular hydrogen ameliorated the METH-induced neurotoxicity and spatial learning and memory impairments. Male C57BL/6 mice received four intraperitoneal METH injections (10 mg/kg, 3-h interval), and stereotypic behaviors and hyperthermia were observed. After METH treatment and behavioral observation, the mice were returned to their home cages, where they received water or hydrogen-rich water (HRW) ad libitum for 7 days. We found that the molecular hydrogen delivered by ad libitum HRW consumption significantly inhibited the METH-induced spatial learning impairment and memory loss evidenced in the Barnes maze and Morris water maze tests. Furthermore, molecular hydrogen significantly restrained the neuronal damage in the hippocampus after high-dose METH exposure. Ad libitum HRW consumption also had an inhibitory effect on the METH-induced increase in the expression of Bax/Bcl-2, cleaved caspase-3, glucose-related protein 78 (GRP 78), CCAAT/enhancer-binding protein homologous protein (CHOP), and p-NF-kB p65 expression and elevation of interleukin (IL)-6 and tumor necrosis factor (TNF)-α levels in the hippocampus. These are the first findings to indicate that hydrogen might ameliorate METH-induced neurotoxicity and has a potential application in reducing the risk of neurodegeneration frequently observed in METH abusers.

Abstract
Background GRP78, the 78-kDa glucose-regulated protein, occupies a significant position in endoplasmic reticulum stress. Emerging evidences have shown that GRP78 induces chemoresistance in several tumors; however, the role of GRP78 in cervical cancer (CVC) still needs to be elucidated clearly. Material/Methods In the present study, we evaluated the expression levels of GRP78 in CVC tissues collected from patients through immunocytochemistry, western blot, and real-time PCR. To explore the exact role of GRP78 in CVC cells in the presence of cisplatin, we generated GRP78 knockdown CVC cells through small interfering RNA. After transfection, the apoptosis rate was assessed by flow cytometry. Then the expression levels of caspase-3, CHOP, and Bcl-2 in GRP78 knockdown cells were determined by western blot. Results The GRP78 levels in CVC tissues were increased significantly. Three types of CVC cells HeLa, SiHa, and C33A were treated with different concentrations of cisplatin and cultured for 12 hours, 24 hours, and 48 hours respectively. And SiHa cells exhibited the highest resistance to cisplatin at all time. Specifically, after 25 μM cisplatin treatment, more than 80% of C33A cells underwent apoptosis, whereas the apoptotic rate of SiHa cells was only 30–40%. Data suggested that GRP78 silencing increased chemo-sensitivity and improved the effects of cisplatin-induced apoptosis in SiHa cells. Moreover, inhibition of GRP78 could upregulate caspase-3 and CHOP expression and downregulate Bcl-2 expression. Conclusions GRP78 may represent a key bio-marker of CVC and silencing GRP78 may strengthen the resistance against cisplatin. GRP78 may be a potential molecular target for CVC therapies in future.

Abstract
Methamphetamine (METH) is a psychostimulant abused around the world. Emerging evidence indicates that METH causes brain damage. However, there are very few reports on METH-induced demyelination. Thioredoxin-1 (Trx-1) is a redox regulating protein and plays the roles in protecting neurons from various stresses. However, whether Trx-1 resists demyelination induced by METH has not been reported. In this study, we found that METH-induced thin myelin sheaths in spinal cord, whereas Trx-1 overexpression transgenic (TG) mice restored the myelin sheaths thickness. The expressions of myelin-associated glycoprotein, myelin basic protein, and cyclin-dependent kinase 5 were decreased by METH, whereas these alterations were blocked in Trx-1 TG mice. The expressions of procaspase-12 and procaspase-3 were decreased by METH, the expression of calpain1 was increased by METH, whereas the alterations were suppressed in Trx-1 TG mice. As same as, the expressions of the extracellular signal-regulated kinase, nuclear factor κB, tumor necrosis factor-alpha, and interleukin-1beta were induced by METH, which were suppressed in Trx-1 TG mice. These data suggest that Trx-1 may play a critical role in resisting the METH-mediated demyelination in spinal cord through regulating endoplasmic reticulum stress and inflammation pathways.

Abstract
Methamphetamine (MA), a psychostimulant drug has been associated with a variety of neurotoxic effects which are thought to be mediated by induction of pro-inflammatory cytokines/chemokines, oxidative stress and damage to blood-brain-barrier. Conversely, the ER stress-mediated apoptosis has been implicated in several neurodegenerative diseases. However, its involvement in MA-mediated neurodegenerative effects remains largely unexplored. The present study was undertaken to assess the effect of MA on ER stress and its possible involvement in apoptosis. For this purpose, SVGA astrocytes were treated with MA, which induced the expressions of BiP and CHOP at both, mRNA and protein levels. This phenomenon was also confirmed in HFA and various regions of mouse brain. Assessment of IRE1α, ATF6 and PERK pathways further elucidated the mechanistic details underlying MA-mediated ER stress. Knockdown of various intermediate molecules in ER stress pathways using siRNA demonstrated reduction in MA-mediated CHOP. Finally, MA-mediated apoptosis was demonstrated via MTT assay and TUNEL staining. The involvement of ER stress in the apoptosis was demonstrated with the help of MTT and TUNEL assays in the presence of siRNA against various ER stress proteins. The apoptosis also involved activation of caspase-3 and caspase-9, which was reversed by knockdown with various siRNAs. Altogether, this is the first report demonstrating mechanistic details responsible for MA-mediated ER stress and its role in apoptosis. This study provides a novel group of targets that can be explored in future for management of MA-mediated cell death and MA-associated neurodegenerative disorders.

Abstract
Methamphetamine (METH) abuse causes serious health problems worldwide, and long-term use of METH disrupts the blood-brain barrier (BBB). Herein, we explored the potential mechanism of endoplasmic reticulum (ER) stress in METH-induced BBB endothelial cell damage in vitro and the therapeutic potential of endoplasmic reticulum stress inhibitors for METH-induced BBB disruption in C57BL/6J mice. Exposure of immortalized BMVEC (bEnd.3) cells to METH significantly decreased cell viability, induced apoptosis, and diminished the tightness of cell monolayers. METH activated ER stress sensor proteins, including PERK, ATF6, and IRE1, and upregulated the pro-apoptotic protein CHOP. The ER stress inhibitors significantly blocked the upregulation of CHOP. Knockdown of CHOP protected bEnd.3 cells from METH-induced cytotoxicity. Furthermore, METH elevated the production of reactive oxygen species (ROS) and induced the dysfunction of mitochondrial characterized by a Bcl2/Bax ratio decrease, mitochondrial membrane potential collapse, and cytochrome c. ER stress release was partially reversed by ROS inhibition, and cytochrome c release was partially blocked by knockdown of CHOP. Finally, PBA significantly attenuated METH-induced sodium fluorescein (NaFluo) and Evans Blue leakage, as well as tight junction protein loss, in C57BL/6J mice. These data suggest that BBB endothelial cell damage was caused by METH-induced endoplasmic reticulum stress, which further induced mitochondrial dysfunction, and that PBA was an effective treatment for METH-induced BBB disruption.

Biomed Pharmacother 2017; 93:490-497. [PMID: 28672279 DOI: 10.1016/j.biopha.2017.06.073] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2017] [Revised: 05/28/2017] [Accepted: 06/20/2017] [Indexed: 12/16/2022] Open
Abstract
Endoplasmic reticulum stress (ERs) has been regarded as an important cause for the pathogenesis of non-small-cell lung cancer (NSCLC). β-elemene is an active component in the essential oil extracted from a medicinal herb, Curcuma wenyujin, and has been reported to be effective against non-small-cell lung cancer (NSCLC). However, the potential effect and underlying mechanisms of β-elemene on regulating ERs to inhibit NSCLC are still unclear. In the present study, A549 cells and Lewis tumor-bearing C57BL/6J mice were established to evaluate this effect. Visualsonics Vevo 2100 Small Animal Dedicated High-frequency Color Ultrasound was performed to observe tumor volume in vivo. 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) was used to evaluate cell vitality of A549 cells. Furthermore, western blotting (WB), immunohistochemistry (IHC) and quantitative reverse transcription polymerase chain reaction (q-PCR) were applied to detect the ERs-related proteins. Flow cytometry was also applied to detect cell apoptosis and assay kit for reactive oxygen species (ROS) generation. Our results showed that β-elemene inhibited lung cancer tumor growth and cell vitality in a dose- and time-dependent manner. Not only that, β-elemene could up-regulate ERs-related proteins like PERK, IRE1α, ATF6, ATF4, CHOP and down-regulate the Bcl-2 expression. More importantly, ERs inhibitor 4-PBA, IRE1α inhibitor STF-083010, ATF6 inhibitor Anti-ATF6 and PERK inhibitor GSK2656157 can all reduce the amplitude of protein expression changes and apoptosis rates, then weaken the anti-tumor effect of β-elemene. Therefore, the present in vivo and in vitro study revealed that the anti-NSCLC effect of β-elemene is closely related to the activation of ERs through PERK/IRE1α/ATF6 pathway, and this might be beneficial for clinical therapy of NSCLC.

Abstract
Methamphetamine (METH) is an illegal and widely abused psychoactive stimulant. METH exposure causes detrimental effects on multiple organ systems, primarily the nervous system, especially dopaminergic pathways, in both laboratory animals and humans. In this study, we hypothesized that Nuclear protein 1 (Nupr1/com1/p8) is involved in METH-induced neuronal apoptosis and autophagy through endoplasmic reticulum (ER) stress signaling pathway. To test this hypothesis, we measured the expression levels of Nupr1, ER stress protein markers CHOP and Trib3, apoptosis-related protein markers cleaved-caspase3 and PARP, as well as autophagy-related protein markers LC3 and Beclin-1 in brain tissues of adult male Sprague-Dawley (SD) rats, rat primary cultured neurons and the rat adrenal pheochromocytoma cells (PC12 cells) after METH exposure. We also determined the effects of METH exposure on the expression of these proteins after silencing Nupr1, CHOP, or Trib3 expression with synthetic small hairpin RNA (shRNA) or siRNA in vitro, and after silencing Nupr1 in the striatum of rats by injecting lentivirus containing shRNA sequence targeting Nupr1 gene to rat striatum. The results showed that METH exposure increased Nupr1 expression that was accompanied with increased expression of ER stress protein markers CHOP and Trib3, and also led to apoptosis and autophagy in rat primary neurons and in PC12 cells after 24 h exposure (3.0 mM), and in the prefrontal cortex and striatum of rats after repeated intraperitoneal injections (15 mg/kg × 8 injections at 12 h intervals). Silencing of Nupr1 expression partly reduced METH-induced apoptosis and autophagy in vitro and in vivo. These results suggest that Nupr1 plays an essential role in METH-caused neuronal apoptosis and autophagy at relatively higher doses and may be a potential therapeutic target in high-dose METH-induced neurotoxicity.

Abstract
Long non-coding RNAs (lncRNAs) display multiple functions including regulation of neuronal injury. However, their impact in methamphetamine (METH)-induced neurotoxicity has rarely been reported. Here, using microarray analysis, we investigated the expression profiling of lncRNAs and mRNAs in primary cultured prefrontal cortical neurons after METH treatment. We observed a difference in lncRNA and mRNA expression between the experimental and sham control groups. Using bioinformatics, we analyzed the highest enriched gene ontology (GO) terms of biological process, cellular component, and molecular function, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and pathway network analysis. Furthermore, an lncRNA-mRNA co-expression sub-network for aberrantly expressed terms revealed possible interactions of lncRNA NR_110713 and NR_027943 with their related genes. Afterwards, three lncRNAs (NR_110713, NR_027943, GAS5) and two mRNAs (Ddit3, Casp12) were targeted to validate the microarray data by qRT-PCR. This presented an overview of lncRNA and mRNA expression profiling and indicated that lncRNA might participate in METH-induced neuronal apoptosis by regulating the coding genes of neurons.

Abstract
Methamphetamine (MA) leads to multiple organs lesions and apoptosis. The aim of this study is to investigate if endoplasmic reticulum stress (ERS) - initiated apoptosis is involved in the chronic pulmonary injury induced by MA. In this study, rats were divided into a control group, methamphetamine 5mg/kg group and methamphetamine 10mg/kg group. This study found that the protein level of GRP78 is higher in M10 group than in control group. PERK signaling and the relevant apoptosis factors were also activated. Morphological measurements showed that protein BAX and CHOP accumulated in the alveolar epithelium and the alveolar walls with epithelium were damaged and that the number of pulmonary alveoli decreased. The findings showed that ERS and PERK pathway are activated and eventually lead to apoptosis. Severe ERS mediated the apoptosis of alveolar epithelium cells as well as decreasing numbers of pulmonary alveoli.

Abstract
BACKGROUND Methamphetamine is a central nervous system stimulant and is one of the agents most commonly abused by illicit drug users which could induce neuron apoptosis when it is used repeatedly and overdosed. Our previous study demonstrated that geranylgeranylacetone (GGA) was an inducer of thioredoxin-1 (Trx-1) and heat shock protein 70 (Hsp70), which played a cytoprotective role against neurotoxicity. METHODS Using the MTT assay, we detected the effect of GGA on cell viability by methamphetamine in rat pheochromocytoma (PC12) cells. Tyrosine hydroxylase, Trx-1, Hsp70, procaspase-9, procaspase-12 and procaspase-3 expression were examined by Western blot analysis. We also detected enzymatic activities of caspase-3 and caspase-9. RESULTS We found that GGA protected PC12 cells from apoptosis caused by methamphetamine. Furthermore, GGA reversed the decreases in Trx-1 and Hsp70 by methamphetamine, and prevented the methamphetamine-induced decreases in procaspase-9 and procaspase-3. On the other hand, GGA prevented the methamphetamine-induced increases in the enzymatic activity of caspase-9 and caspase-3. Procaspase-12 was not changed by any treatment. CONCLUSIONS These results indicate that GGA protects PC12 cells from methamphetamine-induced toxicity by increasing Trx-1 and Hsp70 and by preventing mitochondria pathway-mediated apoptosis. In summary, GGA may be used as a therapy for neurotoxicity induced by methamphetamine.

Abstract
In this study, the effects of peripheral (intraperitoneal) injections of D-amphetamine on feeding behavior were assessed in goldfish. Compared with the saline-injected group, amphetamine injections decreased food intake at doses ranging from 1 to 75 μg/g, but not 0.5 μg/g, but increased locomotor behavior, as indicated by the increased number of total feeding and non-feeding acts, at doses ranging from 2.5 to 25 μg/g. Amphetamine at high doses inhibited both food intake (at 25, 50 and 75 μg/g) and feeding behavior (at 75 μg/g). In the hypothalamus, the expression of orexin was down-regulated, and both CART 1 and CART 2 expressions were up-regulated in amphetamine-treated fish (50 μg/g) as compared to saline-injected fish, but amphetamine treatment had no effect on either hypothalamic TH or TRH expression. In the telencephalon, amphetamine treatment (50 μg/g) up-regulated CART 1, CART 2 and TH mRNA expressions but had no effect on either orexin or TRH. Our results suggest that, as in mammals, the orexin, CART and TH systems might be involved in amphetamine-induced feeding/locomotor responses in goldfish.
