[PMID: 35660562 DOI: 10.1016/j.jtemb.2022.127003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2020] [Revised: 03/08/2022] [Accepted: 05/17/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND As an emerging nanomaterial, nano-alumina is widely used in chemical engineering, food and medicine due to its special physical and chemical properties, and its potential health hazards have attracted attention. OBJECTIVE Aim of this study is to understanding the effect and possible mechanism of nano-alumina on cognitive function in mice. METHODS Male healthy ICR mice were randomly assigned and given nasal drops of saline, nano-alumina (different doses) and micro-alumina for 30 days, respectively. Morris water maze test, step down test and open field test were used to detect learning and memory ability. Blood brain permeability was observed by immunofluorescence staining and lanthanum nitrate tracing, histopathological abnormalities in mice hippocampus was observed by thionine staining, the final determination of oxidative stress level in brain tissue was measured by using oxidative stress index detection kit and the level of LC3-Ⅱ and Caspase-3, 8, 9 proteins were detected by western blot. RESULTS In the cerebral cortex of mice exposed to nano-alumina particles, lanthanum nitrate particles adhered to vascular endothelial cells, and the expression of ZO-1 and Occuldin decreased and morphology was disordered; most neurons in hippocampus CA3 region showed balloon-like swelling and degeneration, nucleoli disappeared and apical dendrites broke; mice exposed to nano-alumina, the escape latency in Morris water maze increased compared with the control group(P < 0.05),and the residence time in the original platform quadrant shortened significantly(P < 0.05);the platform latency was significantly shortened and the number of errors increased in the step down test compared with the control group; the residence time in the center of mice the nano-alumina treated was significantly increased in open field test (P < 0.05). CONCLUSION The nano-alumina particles could be transported into the central nervous system via blood-brain barrier and olfactory bulb, impair learning and memory function in mice, which is more serious than the micro-alumina particles. The apoptosis of mice neurons caused by nano-alumina particles maybe due to the mixed neurotoxic effect of oxidative stress and the elemental toxicity of aluminum itself.

Abstract
In addition to apoptosis, it has also been reported that aluminum (Al) causes necroptosis, a new form of programmed necrosis, which has recently been discovered, in nerve cells, but its molecular mechanism is not elucidated. In order to explore the answer, in this study, we apply for this method that after PC12 cells were exposed to maltol aluminum [200 μM Al(mal)3], siRNA were used as interference technique to explore the role of Tumour necrosis factor receptor 1 (TNFR1), receptor interaction proteins 1 (RIP1) and receptor interaction proteins 3 (RIP3) in necroptosis caused by Al(mal)3. After the end of this research, we demonstrated that, initially, Al(mal)3 could trigger apoptosis and necroptosis in PC12 cells and up-regulate both mRNA and protein expressions of TNFR1, RIP1 and RIP3, also, up-regulate the phosphorylated mixed lineage kinase domain-like protein (MLKL) protein expression. Additionally, in PC12 cells treated with Al(mal)3, suppression of TNFR1 was found to enhance apoptosis and attenuate the expression of RIP1/RIP3 and phosphorylated MLKL. At last, deficiency of RIP1/RIP3 reduced the extent of necroptosis. Briefly, our results verify that the TNFR1-RIP1/RIP3 pathway could be involved in Al(mal)3 induced necroptosis.

Necrostatin-1 Relieves Learning and Memory Deficits in a Zebrafish Model of Alzheimer's Disease Induced by Aluminum. Neurotox Res 2022; 40:198-214. [PMID: 34982355 DOI: 10.1007/s12640-021-00463-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 12/12/2021] [Accepted: 12/14/2021] [Indexed: 12/21/2022]
Abstract
Aluminum (Al) is considered one of the environmental risk factors for Alzheimer's disease (AD). The present study aims to establish a zebrafish AD model induced by Al and explore if necrostation-1 (Nec-1), a specific inhibitor of necroptosis, is effective in relieving learning and memory deficits in the zebrafish AD models. We treated adult zebrafish with aluminum trichloride at various doses for 1 month, followed by a T-maze test to evaluate learning and memory performance. Al concentration, levels of acetylcholine (Ach), and AD-related protein and gene expression in the brain tissue were evaluated in the zebrafish AD models. Our results demonstrated that in the brain tissue of Al-treated zebrafish, Al accumulated, Ach levels decreased, and AD-related genes and proteins increased. As a result, the learning and memory performance of Al-treated zebrafish was impaired. This suggested that a zebrafish AD model was established. To test the effect of Nec-1 on the zebrafish AD model, we added Nec-1 into the culture medium of the Al-treated adult zebrafish. The results demonstrated that Nec-1 could relive the learning and memory deficits, enhance Ach levels and the numbers of neural cells, and impact necroptosis-related gene expression. We concluded that Nec-1 could reverse Al-induced learning and memory impairment and had potential theoretical value in the zebrafish AD model.

Abstract
Neurodegenerative diseases are the most frequent chronic, age-associated neurological pathologies having a major impact on the patient’s quality of life. Despite a heavy medical, social and economic burden they pose, no causative treatment is available for these diseases. Among the important pathogenic factors contributing to neuronal loss during neurodegeneration is elevated oxidative stress resulting from a disturbed balance between endogenous prooxidant and antioxidant systems. For many years, it was thought that increased oxidative stress was a cause of neuronal cell death executed via an apoptotic mechanism. However, in recent years it has been postulated that rather programmed necrosis (necroptosis) is the key form of neuronal death in the course of neurodegenerative diseases. Such assumption was supported by biochemical and morphological features of the dying cells as well as by the fact that various necroptosis inhibitors were neuroprotective in cellular and animal models of neurodegenerative diseases. In this review, we discuss the relationship between oxidative stress and RIP1-dependent necroptosis and apoptosis in the context of the pathomechanism of neurodegenerative disorders. Based on the published data mainly from cellular models of neurodegeneration linking oxidative stress and necroptosis, we postulate that administration of multipotential neuroprotectants with antioxidant and antinecroptotic properties may constitute an efficient pharmacotherapeutic strategy for the treatment of neurodegenerative diseases.

[PMID: 33316730 DOI: 10.1016/j.jtemb.2020.126700] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 10/25/2020] [Accepted: 11/23/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Aluminum is an environmental neurotoxin widely exposed to animals and humans. Studies have shown that Alzheimer's disease (AD) is characterized by abnormally phosphorylated tau and Aβ deposition, aluminum exposure can lead to abnormal phosphorylated tau and Aβ deposition. Numerous epidemiological data and studies have confirmed that ApoEε4 is a risk factor for AD. However, whether there is an interaction effect between aluminum and ApoEε4 has yet to be verified. METHODS SH-SY5Y cells were exposed with AlCl3 and transfected with ApoEε4 respectively. The experimental groups included the blank control group, the low dose group (200 μM AlCl3), the medium dose group (400 μM AlCl3), the high dose group (800 μM AlCl3), empty plasmid group, ApoEε4 group and 400 μM AlCl3+ApoEε4 group. The cell viability was determined by CCK-8 kit after transfection for 48 h.The contents of total tau proteins, tau-181, tau-231, tau-262, tau-396 and Aβ42, were determined by ELISA kit. The interaction between AlCl3 and ApoEε4 was analyzed by factorial design. RESULTS With the increase of aluminum exposure, SH-SY5Y cell viability decreased, and the expression of the total tau, tau-181, tau-231, tau-262, tau-396 and Aβ content increased. The viability of cells transfected with ApoEε4 is significantly lower than control group, and the expressions of total tau, tau-181, tau-231, tau-262, tau-396 and Aβ in ApoEε4 transfected cells were significantly higher than control group. The viability of cells treated with AlCl3 plus ApoEε4 was lower than those treated with, either AlCl3, or ApoEε4. The expression of total tau, tau-181, tau-231, tau-262, tau-396 and Aβ in the cells treated with AlCl3 plus ApoEε4 were significantly higher than those in other groups (p < 0.05). Moreover, analyzing data based on the factorial design, there was existed an interaction between AlCl3 and ApoEε4 (p < 0.05). CONCLUSION Al and ApoEε4 gene can cause morphological changes of SH-SY5Y cells, reduce cell activity, and have obvious cytotoxic effects, and increase the phosphorylation levels of tau and the deposition of Aβ increases. In the presence of both Al and ApoEε4 genes, the two factors interact with each other and show a synergistic effect.

Neurotox Res 2020; 37:525-542.

Abstract
Necroptosis, a recently discovered form of non-apoptotic programmed cell death, can be implicated in many pathological conditions including neuronal cell death. Moreover, an inhibition of this process by necrostatin-1 (Nec-1) has been shown to be neuroprotective in in vitro and in vivo models of cerebral ischemia. However, the involvement of this type of cell death in oxidative stress–induced neuronal cell damage is less recognized. Therefore, we tested the effects of Nec-1, an inhibitor of necroptosis, in the model of hydrogen peroxide (H2O2)-induced cell damage in human neuroblastoma SH-SY5Y and murine hippocampal HT-22 cell lines. The data showed that Nec-1 (10–40 μM) attenuated the cell death induced by H2O2 in undifferentiated (UN-) and neuronal differentiated (RA-) SH-SY5Y cells with a higher efficacy in the former cell type. Moreover, Nec-1 partially reduced cell damage induced by 6-hydroxydopamine in UN- and RA-SH-SY5Y cells. The protective effect of Nec-1 was of similar magnitude as the effect of a caspase-3 inhibitor in both cell phenotypes and this effect were not potentiated after combined treatment. Furthermore, the non-specific apoptosis and necroptosis inhibitor curcumin augmented the beneficial effect of Nec-1 against H2O2-evoked cell damage albeit only in RA-SH-SY5Y cells. Next, it was found that the mechanisms of neuroprotective effect of Nec-1 against H2O2-induced cell damage in SH-SY5Y cells involved the inhibition of lysosomal protease, cathepsin D, but not caspase-3 or calpain activities. In HT-22 cells, Nec-1 was protective in two models of oxidative stress (H2O2 and glutamate) and that effect was blocked by a caspase inhibitor. Our data showed neuroprotective effects of the necroptosis inhibitor, Nec-1, against oxidative stress–induced cell damage and pointed to involvement of cathepsin D inhibition in the mechanism of its action. Moreover, a cell type–specific interplay between necroptosis and apoptosis has been demonstrated.

Abstract
The brain is one of organs vulnerable to aluminum insult. Aluminum toxicity is involved in neurobehavioral deficit, neuronal cell dysfunction, and death. The aim of this study are as follows: (1) to evaluate the repairing efficiency of Necrostatin-1 (Nec-1), a cell death inhibitor, and Z-VAD-FMK, a pan-caspase inhibitor, on Al-induced neurobehavioral deficit and neuronal cell death, in order to evidence the cell death inducing ability of aluminum, and (2) to primarily explore the possibility of treating neuronal cell loss-related disease, such as Alzheimer's disease, with Nec-1 and Z-VAD in Al-induced dementia animal model. We found Nec-1 and Z-VAD-FMK alone or in combination could reduce aluminum-induced learning and memory impairment in mice. Pathohistological results indicated that Nec-1 and Z-VAD-FMK can decrease Al-induced neuronal death cell. In addition, some cell death-associated proteins in cell death signal pathway were inhibited by Nec-1 and Z-VAD-FMK in Al-exposed mice. In conclusions, Nec-1 and Z-VAD-FMK can repair the injury of learning and memory induced by aluminum in mice. Furthermore, Nec-1 was more obvious to repair the injury of learning and memory function compared with Z-VAD-FMK. Nec-1 and Z-VAD-FMK can repair the Al-induced morphological injury of cell and reduce the amounts of dead cell, and repairing effects were more significant at higher doses. The effect of Nec-1 was stronger than Z-VAD-FMK, though their mechanism was different. The combination of them had the strongest effect. Our study evidenced Al-induced neuronal necroptosis and apoptosis existing in animal model and suggested potential therapeutic effects of Nec-1 and Z-VAD-FMK on neuronal cell death in neurodegenerative diseases.

Abstract
Aluminum (Al) exposure has adverse effects on osteoblasts, and the effect might be through autophagy-associated apoptosis. In this study, we showed that aluminum trichloride (AlCl3) could induce autophagy in MC3T3-E1 cells, as demonstrated by monodansylcadaverine (MDC) staining and the expressions of the ATG3, ATG5, and ATG9 genes. We found AlCl3 inhibited MC3T3-E1 cell survival rate and caused apoptosis, as evidenced by CCK-8 assay, Annexin V/PI double staining, and increased expressions of Bcl-2, Bax, and Caspase-3 genes. In addition, increased autophagy induced by rapamycin further attenuated the MC3T3-E1 cell apoptosis rate after AlCl3 exposure. These results support the hypothesis that autophagy plays a protective role in impeding apoptosis caused by AlCl3. Activating autophagy may be a strategy for treatment of Al-induced bone disease.

Abstract
Prostaglandin D2 PGD2 is a major cyclooxygenase metabolite of arachidonic acid produced by mast cells and it is released following allergen challenge in diseases, such as allergic diseases. PGD2 may act as a neuromodulator and as an allergic and inflammatory mediator. In allergic diseases, activated mast cell synthesizes prostaglandin D2 (first cyclo-oxygenate mediator) which has bronchoconstrictive and vasodilating effects and attracts several leukocytes. It has been found that activated mast cells, challenged with physiological and non- physiological secretagogues, release elevated histamine and tryptase and chymase, leukotrienes B4, C4 and D4, 5-hydroxyeicosatetraenoic acid, PGD2, Platelet Activating Factor (PAF), heparin, and high-molecular-weight neutrophil chemotactic factor and cytokines/chemokines. PGD2 exerts its biological activity through the DP and CRTH2 receptors and their cDNA cloning which were characterized 15 years ago. In this report, we revisited the biological effects of arachidonic acid compounds released by activated mast cells in allergic and inflammatory states.

Abstract
Neurodegenerative diseases are a group of chronic progressive disorders characterized by neuronal loss. Necroptosis, a recently discovered form of programmed cell death, is a cell death mechanism that has necrosis-like morphological characteristics. Necroptosis activation relies on the receptor-interacting protein (RIP) homology interaction motif (RHIM). A variety of RHIM-containing proteins transduce necroptotic signals from the cell trigger to the cell death mediators RIP3 and mixed lineage kinase domain-like protein (MLKL). RIP1 plays a particularly important and complex role in necroptotic cell death regulation ranging from cell death activation to inhibition, and these functions are often cell type and context dependent. Increasing evidence suggests that necroptosis plays an important role in the pathogenesis of neurodegenerative diseases. Moreover, small molecules such as necrostatin-1 are thought inhibit necroptotic signaling pathway. Understanding the precise mechanisms underlying necroptosis and its interactions with other cell death pathways in neurodegenerative diseases could provide significant therapeutic insights. The present review is aimed at summarizing the molecular mechanisms of necroptosis and highlighting the emerging evidence on necroptosis as a major driver of neuron cell death in neurodegenerative diseases.

Abstract
Over the past decades, cell apoptosis has been significantly reputed as an accidental, redundant and alternative manner of cell demise which partakes in homeostasis in the development of extensive diseases. Nevertheless, necroptosis, another novel manner of cell death through a caspase-independent way, especially in neurodegenerative diseases remains ambiguous. The cognition of this form of cell demise is helpful to understand other forms of morphological resemblance of necrosis. Additionally, the concrete signal mechanism in the regulation of necroptosis is beneficial to the diagnosis and treatment of neurodegenerative diseases. Recent studies have demonstrated that necroptotic inhibitor, 24(S)-Hydroxycholesterol and partial specific histone deacetylase inhibitors could alleviate pathogenetic conditions of neurodegenerative diseases via necroptosis pathway. In this review, we summarize recent researches about mechanisms and modulation of necroptotic signaling pathways and probe into the role of programmed necroptotic cell demise in neurodegenerative diseases such as Parkinson's disease, Multiple sclerosis, Amyotrophic lateral sclerosis.

Abstract
Programmed cell death is a basic cellular process that is critical to maintaining tissue homeostasis. In contrast to apoptosis, necrosis was previously regarded as an unregulated and uncontrollable process. However, as research has progressed, necrosis, also known as necroptosis or programmed necrosis, is drawing increasing attention, not least becasu of its possible impications for cancer research. Necroptosis exhibits a unique signaling pathway that requires the involvement of receptor interaction protein kinases 1 and 3 (RIP1 and RIP3), mixed lineage kinase domain-like (MLKL), and phosphoglycerate mutase 5 (PGAM5) and can be specifically inhibited by necrostatins. Not only does necroptosis serve as a backup cell death program when apoptosis is inhibited, but it is now recognized to play a pivotal role in regulating various physiological processes and the pathogenesis of a variety of human diseases such as ischemic brain injury, immune system disorders and cancer. The control of necroptosis by various defined trigger factors and signaling pathways now offers the opportunity to target this cellular process for therapeutic purposes. The purpose of this paper is to review current findings concerning the connections between various trigger factors and the RIP1/RIP3 signaling pathway as it relates to necroptosis.

Abstract
Spinal cord injury (SCI) is a common and serious trauma which lacks efficient treatment. Inhibition of cell death in the trauma area is important for spinal cord protection during this process. In this study, necroptosis inhibitor necrostatin-1 (Nec-1) was used to treat SCI rats, to investigate the role of Nec-1 in the recovery of SCI. Nec-1 was found to reduce lesions, cytokines and reactive oxygen species (ROS), improve pathological conditions and blood supply in the spinal cord trauma area. Further study indicated that Nec-1 could inhibit necroptosis by inhibiting RIP1/3-MLKL recruitment and inhibit apoptosis by inhibiting Caspase 3 and Bax while activating Bcl-2. Ethological performance of SCI rats confirmed improvement and protection of physiological function by Nec-1. Nec-1 as a potential treatment for SCI warrants further study. To our knowledge, this is the first study on the role of Nec-1 in the treatment of traumatic SCI. Our research also found inhibition effects of Nec-1 on apoptosis, not only necroptosis - as reported by most publications.

Abstract
Cell death is an integral part of the life of an organism being necessary for the maintenance of organs and tissues. If, however, cell death is allowed to proceed unrestricted, tissue damage and degenerative disease may ensue. Until recently, three morphologically distinct types of cell death were recognized, apoptosis (type I), autophagy (type II) and necrosis (type III). Apoptosis is a highly regulated, genetically determined mechanism designed to dismantle cells systematically (e.g. cells that are no longer functionally viable), via protease (caspase) action, and maintain homeostasis. Autophagy is responsible for the degradation of cytoplasmic material, e.g. proteins and organelles, through autophagosome formation and subsequent proteolytic degradation by lysosomes, and is normally considered in the context of survival although it is sometimes associated with cell death. Necrosis was formerly considered to be an accidental, unregulated form of cell death resulting from excessive stress, although it has been suggested that this is an over-simplistic view as necrosis may under certain circumstances involve the mobilization of specific transduction mechanisms. Indeed, recently, an alternative death pathway, termed necroptosis, was delineated and proposed as a form of ‘programmed necrosis’. Identified with the aid of specific inhibitors called necrostatins, necroptosis shares characteristics with both necrosis and apoptosis. Necroptosis involves Fas/tumour necrosis factor-α death domain receptor activation and inhibition of receptor-interacting protein I kinase, and it has been suggested that it may contribute to the development of neurological and myocardial diseases. Significantly, necrostatin-like drugs have been mooted as possible future therapeutic agents for the treatment of degenerative conditions.
