[PMID: 38154758 DOI: 10.1016/j.etap.2023.104355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 12/22/2023] [Indexed: 12/30/2023]
Abstract
BACKGROUND Ferroptosis is a newly recognized cell death pathway having distinct characteristics compared to traditional cell death pathways such as apoptosis, necroptosis, or autophagy. However, the potential involvement of ferroptosis in bisphenol A (BPA)-induced neurotoxicity has not been well explored so far. In present study, we analyzed the relationship between ferroptosis and BPA-induced neurotoxicity. METHODS In this study, a human neuroblastoma cell line, SH-SY5Y, was treated with BPA, ferrostatin-1 (FS-1, ferroptosis inhibitor) and RSL-3 (ferroptosis inducer). The cell viability was measured using MTT assay. Additionally, the levels of lipid peroxidation, total iron content, reactive oxygen species (ROS) generation, and nitrite content were measured to evaluate the key markers of ferroptosis. To further confirm the involvement of ferroptosis in BPA-induced neurotoxicity, other ferroptosis markers such as glutathione peroxidase (GPx) activity, total glutathione contents and antioxidant parameters were also evaluated. RESULTS The cell viability of SH-SY5Y cells was down-regulated by BPA treatment in a concentration-dependent manner, the cell viability at 0.1 µM concentration was 97.63% whereas at highest BPA concentration i.e. 10 µM, the cell viability was 86.05% (p < 0.0001). Also the antioxidant parameters including catalase and superoxide dismutase activity of neuronal cells were down-regulated upon BPA exposure. However, the levels of lipid peroxidation, total iron, reactive oxygen species, and nitrite contents were increased in a concentration-dependent manner which could be rescued by FS-1 and exacerbated by RSL-3. The total iron in SH-SY5Y cells at 0.1 µM concentration was found to be 1.2 fold (p < 0.05) of control and at highest BPA concentration total iron was about 1.41 fold (p < 0.001) of control. CONCLUSIONS The present study indicated that, ferroptosis plays an important role in the progression of BPA-induced neurotoxicity, and ferroptosis may become a novel target in the treatment of various neurological disorders.

Abstract
Zinc is a crucial trace element in the human body, playing a role in various physiological processes such as oxidative stress, neurotransmission, protein synthesis, and DNA repair. The zinc transporters (ZnTs) family members are responsible for exporting intracellular zinc, while Zrt- and Irt-like proteins (ZIPs) are involved in importing extracellular zinc. These processes are essential for maintaining cellular zinc homeostasis. Imbalances in zinc metabolism have been linked to the development of neurodegenerative diseases. Disruptions in zinc levels can impact the survival and activity of neurons, thereby contributing to the progression of neurodegenerative diseases through mechanisms like cell apoptosis regulation, protein phase separation, ferroptosis, oxidative stress, and neuroinflammation. Therefore, conducting a systematic review of the regulatory network of zinc and investigating the relationship between zinc dysmetabolism and neurodegenerative diseases can enhance our understanding of the pathogenesis of these diseases. Additionally, it may offer new insights and approaches for the treatment of neurodegenerative diseases.

Activation of Angiotensin-converting Enzyme 2 Protects Against Lipopolysaccharide-induced Glial Activation by Modulating Angiotensin-converting Enzyme 2/Angiotensin (1-7)/Mas Receptor Axis. Mol Neurobiol 2023; 60:203-227. [PMID: 36251234 DOI: 10.1007/s12035-022-03061-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 10/03/2022] [Indexed: 12/30/2022]
Abstract
Neuroinflammation is associated with activation of glial cells and pro-inflammatory arm of the central Renin Angiotensin System (RAS) namely, Angiotensin-Converting Enzyme/Angiotensin II/Angiotensin Type 1 Receptor (ACE/Ang II/AT1R) axis. Apart from this, another axis of RAS also exists, Angiotensin-Converting Enzyme 2/Angiotensin (1-7)/Mas Receptor (ACE2/Ang (1-7)/MasR), which counters ACE/Ang II/AT1R axis by showing anti-inflammatory properties. However, the role of ACE2/Ang (1-7)/MasR axis has not been explored in glial activation and neuroinflammation. Hence, the present study tries to unveil the role of ACE2/Ang (1-7)/MasR axis in lipopolysaccharide (LPS)-induced neuroinflammation using diminazene aceturate (DIZE), an ACE2 activator, in astroglial (C6) and microglial (BV2) cells as well as male SD rats. We found that ACE2 activation efficiently prevented LPS-induced changes by decreasing glial activation, inflammatory signaling, cell migration, ROS generation via upregulation of ACE2/Ang (1-7)/MasR signaling. In addition, activation of ACE2/Ang (1-7)/MasR axis by DIZE significantly suppressed the pro-inflammatory ACE/Ang II/AT1R axis by reducing Ang II level in neuroinflammatory conditions induced by LPS in both in vitro and in vivo. ACE2/Ang (1-7)/MasR axis activation further decreased mitochondrial depolarization and apoptosis, hence providing neuroprotection. Furthermore, to validate that the beneficial effect of the ACE2 activator was indeed through MasR, a selective MasR antagonist (A779) was used that significantly blocked the anti-inflammatory effect of ACE2 activation by DIZE. Hence, our study demonstrated that ACE2 activation imparted neuroprotection by enhancing ACE2/Ang (1-7)/MasR signaling which in turn decreased glial activation, neuroinflammation, and apoptosis and improved mitochondrial health.

Nitric Oxide 2023; 130:1-11. [PMID: 36375788 DOI: 10.1016/j.niox.2022.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/25/2022] [Accepted: 11/07/2022] [Indexed: 11/13/2022]
Abstract
Neurodegenerative diseases are a set of diseases in which slow and progressive neuronal loss occurs. Nitric oxide (NO) as a neurotransmitter performs key roles in the stimulation and blockade of various inflammatory processes. Although physiological NO is necessary for protection against a variety of pathogens, reactive oxygen species-mediated oxidative stress induces inflammatory cascades and apoptosis. Activation of glial cells particularly astrocytes and microglia induce overproduction of NO, resulting in neuroinflammation and neurodegenerative disorders. Hence, inhibiting the overproduction of NO is a beneficial therapeutic approach for numerous neuroinflammatory conditions. Several compounds have been explored for the management of neurodegenerative disorders, but they have minor symptomatic benefits and several adverse effects. Phytochemicals have currently gained more consideration owing to their ability to reduce the overproduction of NO in neurodegenerative disorders. Furthermore, phytochemicals are generally considered to be safe and beneficial. The mechanisms of NO generation and their implications in neurodegenerative disorders are explored in this review article, as well as several newly discovered phytochemicals that might have NO inhibitory activity. The current review could aid in the discovery of new anti-neuroinflammatory drugs that can suppress NO generation, particularly during neuroinflammatory and neurodegenerative conditions.

Zhang SY, Liang JJ, Liu YQ. Excessive Zinc Ion Caused PC12 Cell Death Correlating with Inhibition of NOS and Increase of RAGE in Cells. Cell Biochem Biophys 2022; 80:755-761.

Abstract
Zinc ion (Zn2+) is an important functional factor; however, excessive Zn2+ can be toxic. To understand the neurotoxicity of excessive Zn2+ and the underlying mechanism, PC12 cells were treated with excessive Zn2+ and Zn2+ plus N, N, N', N'-Tetrakisethylenediamine (TPEN), a zinc ion chelator agent. Trypan blue and 3-(4,5-dimethyl-2- thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, thiazolyl blue tetrazolium bromide (MTT) assays were used to test cell viability; the relative kits were used to detect the activity of NOS synthase and the content of the receptor for advanced glycation end product (RAGE) in cells. We observed that excessive zinc caused PC12 cell damage and that TPEN partially reversed cell damage caused by excessive zinc. In addition, excessive zinc decreased total nitric oxide synthase (TNOS) activity in cells, in which constitutive nitric oxide synthase (cNOS) activity was significantly reduced; however, inducible nitric oxide synthase (iNOS) activity was extremely promoted. Moreover, excessive zinc upregulated the expression of RAGE, and TPEN effectively reversed the increase in RAGE induced by excessive zinc ions. Therefore, we concluded that excessive zinc caused PC12 cell damage, correlating with the inhibition of NOS and increase of RAGE induced in cells.

Abstract
Mitochondrial dysfunction and nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase) are the major sources of augmentation in free radical generation leading to neurodegeneration. Although NADPH oxidase involvement is reported in zinc (Zn)-induced neurodegeneration, contribution of the mitochondrial dysfunction and its association with NADPH oxidase are not known. Therefore, the study was aimed to decipher the role of mitochondrial dysfunction and its link with NADPH oxidase in Zn-induced Parkinsonism. Zn reduced the motor activities, the number of tyrosine hydroxylase (TH)-positive neurons, and level of TH protein. Conversely, Zn increased the mitochondrial reactive oxygen species (ROS) production, lipid peroxidation (LPO), and superoxide dismutase (SOD) activity and reduced the mitochondrial membrane potential and catalytic activities of complex I and III. Zn also attenuated B-cell lymphoma-2 (Bcl-2) and pro-caspase 9/3 levels and augmented the translocation of cytosolic Bcl-2 associated X (Bax) protein to the mitochondria and cytochrome c release into cytosol from the mitochondria. Cyclosporine A, a mitochondrial outer membrane transition pore inhibitor and apocynin, a NADPH oxidase inhibitor, independently, ameliorated the Zn-induced changes. Similarly, Zn reduced cell viability through mitochondrial dysfunction and apoptosis in human neuroblastoma SH-SY5Y cells, which were notably normalized in the presence of cyclosporine or apocynin. The results demonstrate that mitochondrial dysfunction contributes to Zn-induced neurodegeneration, which could be partially aided by the NADPH oxidase.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2021; 178:104944. [PMID: 34446210 DOI: 10.1016/j.pestbp.2021.104944] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 07/28/2021] [Accepted: 07/28/2021] [Indexed: 06/13/2023]
Abstract
Maneb (MB)- and paraquat (PQ)-induced oxidative stress in rat polymorphonuclear leukocytes (PMNs) is regulated in parallel by cytochrome P450 2E1 (CYP2E1) and inducible nitric oxide synthase (iNOS). However, mechanism underlying their regulation is not yet understood. The study investigated the role of nuclear factor- kappa B (NF-κB) and mitogen-activated protein kinase/extracellular signal regulated kinase/protein kinase C (MEK/ERK/PKC) pathway in the regulation of iNOS- and CYP2E1-induced oxidative stress in PMNs. MB + PQ-induced changes in nitrite content, lipid peroxidation (LPO), iNOS expression/activity and inflammatory mediators were alleviated by aminoguanidine (AG), an iNOS inhibitor, without any change in CYP2E1. Alternatively, diallyl sulphide (DAS), a CYP2E1 inhibitor, rescued from MB + PQ-induced changes in CYP2E1 activity/expression, free radical generation, superoxide dismutase (SOD) activity, LPO and pro-inflammatory cytokines without any alterations in nitrite content and iNOS activity/expression. Pyrrolidine dithiocarbamate (PDTC), NF-κB inhibitor, did not alter CYP2E1 but mitigated free radical generation, SOD activity, LPO, nitrite content, iNOS activity/expression and levels of pro-inflammatory cytokines (tumor necrosis factor-α, interleukine-1β and interleukine-4). Ex-vivo treatment with MEK inhibitor (PD98059), ERK1/2 inhibitor (AG126) or PKC inhibitor (rottlerin) ameliorated MB + PQ-induced increase in free radical generation and CYP2E1 activity/expression in PMNs. While PD98059 and AG126 abated MB + PQ-induced increase in ERK1/2, PKC-α/δ and CYP2E1 levels, rottlerin restored PKC-α/δ and CYP2E1 towards normalcy without affecting ERK1/2 level in MB + PQ-treated group. The results suggest that iNOS and CYP2E1 contributing to MB + PQ-induced oxidative stress in rat PMNs exhibit differential regulatory mechanisms. The inflammatory mediators regulate iNOS expression while CYP2E1 expression is triggered via MEK-ERK1/2-PKC pathway.

Abstract
Since the discovery of manifest Zn deficiency in 1961, the increasing number of studies demonstrated the association between altered Zn status and multiple diseases. In this chapter, we provide a review of the most recent advances on the role of Zn in health and disease (2010-20), with a special focus on the role of Zn in neurodegenerative and neurodevelopmental disorders, diabetes and obesity, male and female reproduction, as well as COVID-19. In parallel with the revealed tight association between ASD risk and severity and Zn status, the particular mechanisms linking Zn2+ and ASD pathogenesis like modulation of synaptic plasticity through ProSAP/Shank scaffold, neurotransmitter metabolism, and gut microbiota, have been elucidated. The increasing body of data indicate the potential involvement of Zn2+ metabolism in neurodegeneration. Systemic Zn levels in Alzheimer's and Parkinson's disease were found to be reduced, whereas its sequestration in brain may result in modulation of amyloid β and α-synuclein processing with subsequent toxic effects. Zn2+ was shown to possess adipotropic effects through the role of zinc transporters, zinc finger proteins, and Zn-α2-glycoprotein in adipose tissue physiology, underlying its particular role in pathogenesis of obesity and diabetes mellitus type 2. Recent findings also contribute to further understanding of the role of Zn2+ in spermatogenesis and sperm functioning, as well as oocyte development and fertilization. Finally, Zn2+ was shown to be the potential adjuvant therapy in management of novel coronavirus infection (COVID-19), underlining the perspectives of zinc in management of old and new threats.

Abstract
Reactive nitrogen species (RNS) and reactive oxygen species (ROS), collectively known as reactive oxygen and nitrogen species (RONS), are the products of normal cellular metabolism and interact with several vital biomolecules including nucleic acid, proteins, and membrane lipids and alter their function in an irreversible manner which can lead to cell death. There is an imperative role for oxidative stress in the pathogenesis of cognitive impairments and the development and progression of neural injury. Elevated production of higher amounts of nitric oxide (NO) takes place in numerous pathological conditions, such as neurodegenerative diseases, inflammation, and ischemia, which occur concurrently with elevated nitrosative/oxidative stress. The enzyme nitric oxide synthase (NOS) is responsible for the generation of NO in different cells by conversion of L-arginine (Arg) to L-citrulline. Therefore, the NO signaling pathway represents a viable therapeutic target. Naturally occurring polyphenols targeting the NO signaling pathway can be of major importance in the field of neurodegeneration and related complications. Here, we comprehensively review the importance of NO and its production in the human body and afterwards highlight the importance of various natural products along with their mechanisms against various neurodegenerative diseases involving their effect on NO production.

Zinc, but not paracetamol, prevents depressive-like behavior and sickness behavior, and inhibits interferon-gamma and astrogliosis in rats. Brain Behav Immun 2020; 87:489-497.

Abstract
Considering all mental and addictive disorders, depression is the most responsible for years of life lost due to premature mortality and disability. Antidepressant drugs have limited effectiveness. Depression can be triggered by immune/inflammatory factors. Zinc and paracetamol interfere with immune system and have demonstrated beneficial effects on depression treatment when administered concomitant with antidepressant drugs. The objective of this study was to test zinc and/or paracetamol as treatments of depressive-like behavior, sickness behavior, and anxiety in rats, as well as to understand the central and peripheral mechanisms involved. Sickness behavior and depressive-like behavior were induced in rats with repetitive lipopolysaccharide (LPS, 1 mg/kg for two consecutive days) administrations. Rats received zinc and/or paracetamol for three consecutive days. Sickness behavior (daily body weight and open field general activity); anxiety (light-dark test); depressive-like/antidepressant behavior (forced swim test); plasma corticosterone and interferon (IFN)-gamma levels; and glial fibrillary acidic protein (GFAP) and tyrosine hydroxylase (TH) brain expression were evaluated. LPS induced sickness behavior and depressive-like behavior, as well as elevated IFN-gamma levels and increased GFAP expression. Zinc prevented both behavioral and biochemical impairments. Paracetamol and zinc + paracetamol association induced only slight beneficial effects. Anxiety, corticosterone, and TH do not seem be related with depression and the other behavioral and neuroimmune changes. In conclusion, zinc treatment was beneficial for sickness behavior and depressive-like behavior without concomitant administration of antidepressants. IFN-gamma and GFAP were linked with the expression of sickness behavior and depressive-like behavior and were also involved with the antidepressant effects. Therefore, zinc, IFN-gamma, and GFAP pathways should be considered for depression treatment.

Postnatal zinc or paraquat administration increases paraquat or zinc-induced loss of dopaminergic neurons: insight into augmented neurodegeneration. Mol Cell Biochem 2020; 467:27-43. [PMID: 32060784 DOI: 10.1007/s11010-020-03694-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Accepted: 01/29/2020] [Indexed: 12/25/2022]
Abstract
Epidemiological evidences have shown an association of exposure to pesticides or heavy metals with increased incidences of Parkinson's disease (PD) in humans. Exposure to pesticides or metals during the decisive period of the brain development increases the susceptibility of dopaminergic neurons upon re-exposure in adult rodents. However, the effect of early life exposure to pesticide on the heavy metal-induced neurodegeneration or heavy metal on pesticide-induced neurodegeneration is not yet explored. The current study explored the effect of developmental exposure to zinc (Zn), a metal or paraquat (PQ), a pesticide on the nigrostriatal dopaminergic neurons of rats challenged to Zn or PQ during adulthood. Exposure of Zn or PQ during adulthood alone exhibited marked reduction in motor activities, striatal dopamine and metabolites, glutathione content and number of dopaminergic neurons. However, the levels of lipid peroxidation, protein carbonyls, superoxide dismutase activity, pro-inflammatory cytokines and 4-hydroxynonenal-protein adducts were increased. While the expression of vesicular monoamine transporter-2 and tyrosine hydroxylase were attenuated, dopamine transporter and microglial marker Iba-1 expression, activated microglia, nuclear factor-kappa B activation, mitochondrial cytochrome c release and caspase-3/9 activation were augmented following Zn or PQ exposure. Albeit postnatal alone exposure did not alter any of the studied parameters, the developmental administration of Zn/PQ in re-challenged adult rats produced more pronounced changes in the aforementioned variables as compared with adulthood Zn or PQ alone intoxicated animals. The results demonstrate that postnatal Zn/PQ intoxication dents the oxidative stress, inflammation, cell death and dopamine metabolism and storage regulating machineries, which speed up the toxicant-induced degeneration during adulthood.

Thymoquinone therapy remediates elevated brain tissue inflammatory mediators induced by chronic administration of food preservatives. Sci Rep 2019; 9:7026. [PMID: 31065039 PMCID: PMC6505027 DOI: 10.1038/s41598-019-43568-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 04/28/2019] [Indexed: 02/06/2023] Open
Abstract
Continuous exposure to preservatives such as nitrite salts has deleterious effects on different organs. Meanwhile, Nigella sativa oil can remediate such organ dysfunction. Here, we studied the effect of consumption of thymoquinone (TQ); the main component of Nigella sativa oil on the brain damage induced by sodium nitrite. Forty adult male rats were daily given oral gavage of sodium nitrite (80 mg/kg) with or without thymoquinone (50 mg/kg). Oxidative stress, cytokines of inflammation, fibrotic elements and apoptotic markers in brain tissue were measured. Exposure to sodium nitrite (SN) resulted in increased levels of malondialdehyde, TGF-β, c-reactive protein, NF-κB, TNF-α, IL-1β and caspase-3 associated with reduced levels of glutathione, cytochrome c oxidase, Nrf2 and IL-10. However, exposure of rats’ brain tissues to thymoquinone resulted ameliorated all these effects. In conclusion, thymoquinone remediates sodium nitrite-induced brain impairment through several mechanisms including attenuation of oxidative stress, retrieving the reduced concentration of glutathione, blocks elevated levels of pro-inflammatory cytokines, restores cytochrome c oxidase activity, and reducing the apoptosis markers in the brain tissues of rats.
