Biomed Pharmacother 2023; 165:115089. [PMID: 37418975 DOI: 10.1016/j.biopha.2023.115089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 06/20/2023] [Accepted: 06/26/2023] [Indexed: 07/09/2023] Open
Abstract
Traumatic brain injury (TBI) is a pathology of great social impact, affecting millions of people worldwide. Despite the scientific advances to improve the management of TBI in recent years, we still do not have a specific treatment that controls the inflammatory process after mechanical trauma. The discovery and implementation of new treatments is a long and expensive process, making the repurpose of approved drugs for other pathologies a clinical interest. Tibolone is a drug in use for the treatment of symptoms associated with menopause and has been shown to have a broad spectrum of actions by regulating estrogen, androgen and progesterone receptors, whose activation exerts potent anti-inflammatory and antioxidant effects. In the present study, we aimed to investigate the therapeutic potential of the tibolone metabolites 3α-Hydroxytibolone, 3β-Hydroxytibolone, and Δ4-Tibolone as a possible therapy in TBI using network pharmacology and network topology analysis. Our results demonstrate that the estrogenic component mediated by the α and β metabolites can regulate synaptic transmission and cell metabolism, while the Δ metabolite may be involved in modulating the post-TBI inflammatory process. We identified several molecular targets, including KDR, ESR2, AR, NR3C1, PPARD, and PPARA, which are known to play critical roles in the pathogenesis of TBI. Tibolone metabolites were predicted to regulate the expression of key genes involved in oxidative stress, inflammation, and apoptosis. Overall, the repurposing of tibolone as a neuroprotective treatment for TBI holds promise for future clinical trials. However, further studies are needed to confirm its efficacy and safety in TBI patients.

Abstract
The progression of neurological diseases is mainly attributed to oxidative stress, apoptosis, inflammation, and trauma, making them a primary public concern. Since no drugs can stop these neurological disorders from happening, active phytochemical intervention has been suggested as a possible treatment. Among the several phytochemicals being studied for their potential health advantages, tanshinone-IIA (Tan-IIA ) stands out due to its wide range of therapeutic effects. Tan-IIA, derived from the Salvia miltiorrhiza plant, is a phenanthrenequinone. The pharmacological characteristics of Tan-IIAagainst various neurodegenerative and neuropsychiatric illnesses have led researchers to believe that the compound possesses neuroprotective potential. Tan-IIA has therapeutic potential in treating neurological diseases due to its capacity to cross the blood-brain barrier and its broad range of activities. In treating neurological disorders, Tan-IIA has been shown to have neuroprotective effects such as anti-apoptotic, anti-inflammatory, BBB protectant, and antioxidant properties. This article concisely summarises the latest scientific findings about the cellular and molecular aspects of Tan-IIA neuroprotection in relation to various neurological diseases. The results of preclinical studies on Tan-IIA provide insight into its potential application in future therapeutic development. This molecule rapidly establishes as a prominent bioactive compound for clinical research.

Abstract
Glial cells are non-neuronal elements of the nervous system (NS) and play a central role in its development, maturation, and homeostasis. Glial cell interest has increased, leading to the discovery of novel study fields. The CRISPR/Cas system has been widely employed for NS understanding. Its use to study glial cells gives crucial information about their mechanisms and role in the central nervous system (CNS) and neurodegenerative disorders. Furthermore, the increasingly accelerated discovery of genes associated with the multiple implications of glial cells could be studied and complemented with the novel screening methods of high-content and single-cell screens at the genome-scale as Perturb-Seq, CRISP-seq, and CROPseq. Besides, the emerging methods, GESTALT, and LINNAEUS, employed to generate large-scale cell lineage maps have yielded invaluable information about processes involved in neurogenesis. These advances offer new therapeutic approaches to finding critical unanswered questions about glial cells and their fundamental role in the nervous system. Furthermore, they help to better understanding the significance of glial cells and their role in developmental biology.

Integrated Metabolomics and Lipidomics Reveal High Accumulation of Glycerophospholipids in Human Astrocytes under the Lipotoxic Effect of Palmitic Acid and Tibolone Protection. Int J Mol Sci 2022; 23:ijms23052474.

Abstract
Lipotoxicity is a metabolic condition resulting from the accumulation of free fatty acids in non-adipose tissues which involves a series of pathological responses triggered after chronic exposure to high levels of fatty acids, severely detrimental to cellular homeostasis and viability. In brain, lipotoxicity affects both neurons and other cell types, notably astrocytes, leading to neurodegenerative processes, such as Alzheimer (AD) and Parkinson diseases (PD). In this study, we performed for the first time, a whole lipidomic characterization of Normal Human Astrocytes cultures exposed to toxic concentrations of palmitic acid and the protective compound tibolone, to establish and identify the set of potential metabolites that are modulated under these experimental treatments. The study covered 3843 features involved in the exo- and endo-metabolome extracts obtained from astrocytes with the mentioned treatments. Through multivariate statistical analysis such as PCA (principal component analysis), partial least squares (PLS-DA), clustering analysis, and machine learning enrichment analysis, it was possible to determine the specific metabolites that were affected by palmitic acid insult, such as phosphoethanolamines, phosphoserines phosphocholines and glycerophosphocholines, with their respective metabolic pathways impact. Moreover, our results suggest the importance of tibolone in the generation of neuroprotective metabolites by astrocytes and may be relevant to the development of neurodegenerative processes.

Aesculin offers increased resistance against oxidative stress and protective effects against Aβ-induced neurotoxicity in Caenorhabditis elegans. Eur J Pharmacol 2022; 917:174755.

Abstract
Aesculin, a coumarin compound, is one of the major active ingredients of traditional Chinese herbal medicine Qinpi (Cortex Fraxini), which has been reported to exhibit antioxidative, anti-inflammatory and neuroprotective properties against oxidative stress and cellular apoptosis. However, the regulatory mechanisms remain poorly characterized in vivo. This research was performed to explore the underlying molecular mechanisms behind aesculin response conferring oxidative stress resistance, and the protective effects on amyloid-β (Aβ)-mediated neurotoxicity in Caenorhabditis elegans. Study indicated that aesculin plays the protective roles for C. elegans against oxidative stress and Aβ-mediated neurotoxicity and reduces the elevated ROS and MDA contents through enhancement of antioxidant defenses. The KEGG pathway analysis suggested that the differentially expressed genes are mainly involved in longevity regulating pathway, and the nuclear translocation of DAF-16 and the RNAi of daf-16 and hsf-1 indicated that DAF-16 and HSF-1 play critical roles in integrating upstream signals and inducing the expressions of stress resistance-related genes. Furthermore, the up-regulated expressions of their target genes such as sod-3 and hsp-16.2 were confirmed in transgenic GFP reporter strains CF1553 and CL2070, respectively. These results indicated that the regulators DAF-16 and HSF-1 elevate stress resistance of C. elegans by modulating stress-responsive genes. Further experiments revealed that aesculin is capable of suppressing Aβ-induced oxidative stress and apoptosis and improves chemosensory behavior dysfunction in Aβ-transgenic nematodes. In summary, this study suggested that aesculin offers increased resistance against oxidative stress and protective effects against Aβ-induced neurotoxicity through activation of stress regulators DAF-16 and HSF-1 in nematodes.

Abstract
Recent epidemiological and genetic studies have revealed an interconnection between schizophrenia and breast cancer. The mutual underlying pathophysiological mechanisms may be immunologically driven. A new cluster of molecules called alarmins may be involved in sterile brain inflammation, and we have already reported the potential impact of interleukin-33 (IL-33) on positive symptoms onset and the role of its soluble trans-membranes full length receptor (sST2) on amelioration of negative symptoms in schizophrenia genesis. Furthermore, these molecules have already been shown to be involved in breast cancer etiopathogenesis. In this review article, we aim to describe the IL-33/suppressor of tumorigenicity 2 (ST2) axis as a crossroad in schizophrenia-breast cancer comorbidity. Considering that raloxifene could be tissue-specific and improve cognition and that tamoxifen resistance in breast carcinoma could be improved by strategies targeting IL-33, these selective estrogen receptor modulators could be useful in complementary treatment. These observations could guide further somatic, as well as psychiatric therapeutical protocols by incorporating what is known about immunity in schizophrenia.

Role of CD36 in Palmitic Acid Lipotoxicity in Neuro-2a Neuroblastoma Cells. Biomolecules 2021; 11:biom11111567.

Abstract
Elevated level of palmitic acid (PA), a long-chain saturated fatty acid (SFA), is lipotoxic to many different types of cells including Neuro-2a (N2a) neuroblastoma cells. CD36 is a multifunctional membrane glycoprotein that acts as a fatty acid translocase (FAT) facilitating the transport of long-chain free fatty acids (FFAs) into cells, serves a fatty acid (FA) sensing function in areas including taste buds and the proximal gut, and acts as a scavenger receptor that binds to many ligands, including FAs, collagen, oxidized low-density lipoproteins, and anionic phospholipids. However, the involvement of CD36 in FA uptake and PA lipotoxicity in N2a cells remains unclear. In this study, we examined FA uptake in BSA- and PA-treated N2a cells and investigated the involvement of CD36 in FA uptake and PA lipotoxicity in N2a cells. Our data showed that PA treatment promoted FA uptake in N2a cells, and that treatment with sulfo-N-succinimidyl oleate (SSO), a CD36 inhibitor, significantly decreased FA uptake in BSA- and PA-treated N2a cells, and ameliorated PA-induced decrease of cell viability, decrease of diploid cells, and increase of tetraploid cells. We also found that CD36 knockdown significantly decreased FA uptake in both BSA- and PA-treated cells as compared to their corresponding wild-type controls, and dramatically attenuated PA-induced cell cycle defects in N2a cells. Our data suggest that CD36 may play a critical role in FA uptake and PA lipotoxicity in N2a cells. CD36 may therefore represent a regulatory target against pathologies caused by excess FAs.

Lycopene abrogates obesity-provoked hyperactivity of neurosignalling enzymes, oxidative stress and hypothalamic inflammation in female Wistar rats. Neurochem Int 2021; 149:105125.

Abstract
Obesity, a global epidemic, has been strongly associated with impairment of brain function. Lycopene has several therapeutic properties and can cross the blood-brain barrier. However, its effects on obesity-provoked brain dysfunction remain unexplored. This study evaluated the potential remediating effects of lycopene on obesity-induced neurological derangements. Thirty-six female Wistar rats (150-200g) were distributed in six groups (n = 6); normal control, obese control, obese + lycopene (20 mg/kg), obese + lycopene (40 mg/kg), normal + lycopene (20 mg/kg), and normal + lycopene (40 mg/kg). Obesity was induced by feeding rats with the Western diet for eight weeks, while normal rats received the control diet. Afterwards, the brain was excised and processed for biochemical, gene expression analyses, and histological evaluations. Obesity-induced brain dysfunction was hallmarked by reduced brain organosomatic index, accumulation of lipids in the cerebrum, and hyperactivity of neurotransmitters-metabolizing enzymes (AChE, ADA, MAO-A, 5'-nucleotidase, and NTPdase). Also, obese rats had decreased antioxidant capacity, with increased oxidative damage, while the expressions of NF-κβ p65 and pro-inflammatory cytokines (IL-1β and IL-6) were elevated in the hypothalamus. These observations were validated by histomorphological evaluations, which showed vacuolation in the brain of obese rats. Treatment with lycopene significantly (p < 0.05) reduced the elevated lipid contents and activities of neuronal enzymes, alleviated oxidative stress and inflammation, while improving the histology of the brain, in a dose-dependent manner. Thus, lycopene abrogates obesity-provoked brain dysfunction and may present a safe and viable therapeutic option for the management of neurological perturbations associated with obesity.

Abstract
In mammals, sexual hormones such as estrogens play an essential role in maintaining brain homeostasis and function. Estrogen deficit in the brain induces many undesirable symptoms such as learning and memory impairment, sleep and mood disorders, hot flushes, and fatigue. These symptoms are frequent in women who reached menopausal age or have had ovariectomy and in men and women subjected to anti-estrogen therapy. Hormone replacement therapy alleviates menopause symptoms; however, it can increase cardiovascular and cancer diseases. In the search for therapeutic alternatives, medicinal plants and specific synthetic and natural molecules with estrogenic effects have attracted widespread attention between the public and the scientific community. Various plants have been used for centuries to alleviate menstrual and menopause symptoms, such as Cranberry, Ginger, Hops, Milk Thistle, Red clover, Salvia officinalis, Soy, Black cohosh, Turnera diffusa, Ushuva, and Vitex. This review aims to highlight current evidence about estrogenic medicinal plants and their pharmacological effects on cognitive deficits induced by estrogen deficiency during menopause and aging.

Abstract
Since adipose tissue (AT) can upregulate pro-inflammatory interleukins (ILs) via storing extra lipids in obesity, obesity is considered the leading cause of chronic low-grade inflammation. These ILs can pave the way for the infiltration of immune cells into the AT, ultimately resulting in low-grade inflammation and dysregulation of adipocytes. IL-1, which is divided into two subclasses, i.e., IL-1α and IL-1β, is a critical pro-inflammatory factor. In obesity, IL-1α and IL-1β can promote insulin resistance via impairing the function of adipocytes and promoting inflammation. The current study aims to review the detailed molecular mechanisms and the roles of IL-1α and IL-1β and their antagonist, interleukin-1 receptor antagonist(IL-1Ra), in developing obesity-related inflammatory complications, i.e., type II diabetes (T2D), non-alcoholic steatohepatitis (NASH), atherosclerosis, and cognitive disorders. Besides, the current study discusses the recent advances in natural drugs, synthetic agents, and gene therapy approaches to treat obesity-related inflammatory complications via suppressing IL-1.

Abstract
Neuroinflammation has been implicated in the pathogenesis of neurodegeneration and is now accepted as a common molecular feature underpinning neuronal damage and death. Palmitic acid (PA) may represent one of the links between diet and neuroinflammation. The aims of this study were to assess whether PA induced toxicity in neuronal cells by modulating microglial inflammatory responses and/or by directly targeting neurons. We also determined the potential of oleic acid (OA), a monounsaturated fatty acid, to counteract inflammation and promote neuroprotection. We measured the ability of PA to induce the secretion of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), the induction of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signalling pathways, as well as the phosphorylation of c-Jun, and the expression of inducible nitric oxide synthase (iNOS). Finally, to determine whether PA exerted an indirect neurotoxic effect on neuronal cells, we employed a microglia-neuron co-culture paradigm where microglial cells communicate with neuronal cells in a paracrine fashion. Herein, we demonstrate that PA induces the activation of the NF-κB signalling pathway and c-Jun phosphorylation in N9 microglia cells, in the absence of increased cytokine secretion. Moreover, our data illustrate that PA exerts an indirect as well as a direct neurotoxic role on neuronal PC12 cells and these effects are partially prevented by OA. These results are important to establish that PA interferes with neuronal homeostasis and suggest that dietary PA, when consumed in excess, may induce neuroinflammation and possibly concurs in the development of neurodegeneration.

Tucumã (Astrocaryum aculeatum) prevents memory loss and oxidative imbalance in the brain of rats with hyperlipidemia. J Food Biochem 2021; 45:e13636. [PMID: 33533491 DOI: 10.1111/jfbc.13636] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 12/21/2020] [Accepted: 01/14/2021] [Indexed: 01/10/2023]
Abstract
Hyperlipidemia generates deposition of lipids, inflammation, and oxidative damage in cells and tissues, including those of the brain. Tucumã (Astrocaryum aculeatum) fruits contain bioactive compounds with antioxidant and anti-inflammatory effects. We evaluated the action of Tucumã extract on memory and brain cortex redox balance in hyperlipidemic rats. For 30 days, Wistar rats received Tucumã extract (250 mg/kg). Then, hyperlipidemia was induced by intraperitoneal administration of Poloxamer-407. Twenty-four hours later, the object recognition index was measured. The animals were euthanized for sample collection 36 hr postinduction. Hyperlipidemic animals showed memory loss and an imbalance between reactive species and intrinsic antioxidants. We found that Tucumã prevented memory loss and protein and lipid oxidative damage and prompted a better antioxidant response in the cerebral cortex of rats with hyperlipidemia. These findings suggest a neuroprotective effect and nutraceutical potential of Tucumã. PRACTICAL APPLICATIONS: In the present work, we demonstrated that induced hyperlipidemia in rats caused memory loss and redox unbalance, both factors prevented by the administration of Tucumã (Astrocaryum aculeatum) extract. Two aims were fulfilled with these results. The first was to show that hyperlipidemia affected brain function through oxidative damage and concerned basic research. The second was to offer a therapy that prevented this harm and could be applied in the clinic. Tucumã has ethnopharmacological importance through the consumption of fruits or the administration of extracts and oils by a population that was shown to enjoy improved health and longevity. Here, we show evidence that Tucumã contributes to the maintenance of brain health by preventing memory loss and oxidative damage, a nutraceutical supplement that may aid the prevention of vascular, inflammatory, and brain diseases.

Cross-talk between lipid homeostasis and endoplasmic reticulum stress in neurodegeneration: Insights for HIV-1 associated neurocognitive disorders (HAND). Neurochem Int 2020; 141:104880.

Abstract
The dysregulation of lipid homeostasis is emerging as a hallmark of many CNS diseases. As aberrant protein regulation is suggested to be a shared pathological feature amongst many neurodegenerative conditions, such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD), disruptions in neuronal lipid processing may contribute to disease progression in the CNS. Specifically, given the endoplasmic reticulum (ER) dual role in lipid homeostasis as well as protein quality control (PQC) via unfolded protein response (UPR), lipid dysregulation in the CNS may converge on ER functioning and constitute a crucial mechanism underlying aberrant protein aggregation. In the current review, we discuss the diverse roles of lipid species as essential components of the CNS. Moreover, given the importance of both lipid dysregulation and protein aggregation in pathology of CNS diseases, we attempt to assess the potential downstream cross-talk between lipid dysregulation and ER dependent PQC mechanisms, with special focus on HIV-associated neurodegenerative disorders (HAND).

Abstract
Free or non-esterified fatty acids are the product of lipolysis of storage fat, i.e. triacylglyceroles. When the amount of fat exceeds the capacity of lipid-storing organs, free fatty acids affect and damage other non-lipid-storing organs. This process is termed lipotoxicity. Within a cell, free fatty acids can damage mitochondria, and lipotoxicity-induced mitochondrial damage has been associated recently with Peroxisomal Biogenesis Disorders. Drosophila melanogaster has a rising popularity as a model organism for metabolic diseases, but an optimized assay for measuring free fatty acids in Drosophila tissue samples is missing. Here we present a detailed protocol highlighting technical requirements and pitfalls to determine free fatty acids in samples of Drosophila tissue. The colorimetric assay allows the reproducible and cost-efficient measurement of free fatty acids in a 96 well plate format. We used our assay to determine changes in free fatty acid levels in different developmental stages and feeding conditions, and found that larvae and adults have different patterns of free fatty acid formation during starvation. Our assay is a valuable tool in the modeling of metabolic diseases with Drosophila melanogaster.

Abstract
The aggregation of β-amyloid (Aβ) peptide in Alzheimer's disease (AD) is characterized by mitochondrial dysfunction and mitophagy impairment. Mitophagy is a homeostatic mechanism by which autophagy selectively eliminates damaged mitochondria. Valinomycin is a respiratory chain inhibitor that activates mitophagy via the PINK1/Parkin signaling pathway. However, the mechanism underlying the association between mitophagy and valinomycin in Aβ formation has not been explored. Here, we demonstrate that genetically modified (N2a/APP695swe) cells overexpressing a mutant amyloid precursor protein (APP) serve as an in vitro model of AD for studying mitophagy and ATP-related metabolomics. Our results prove that valinomycin induced a time-dependent increase in the mitophagy activation of N2a/APP695swe cells as indicated by increased levels of PINK1, Parkin, and LC3II as well as increased the colocalization of Parkin-Tom20 and fewer mitochondria (indicated by decreased Tom20 levels). Valinomycin significantly decreased Aβ1-42 and Aβ1-40 levels after 3 h of treatment. ATP levels and ATP-related metabolites were significantly increased at this time. Our findings suggest that the elimination of impaired mitochondria via valinomycin-induced mitophagy ameliorates AD by decreasing Aβ and improving ATP levels.
