Diphenyl Diselenide Attenuates Mitochondrial Damage During Initial Hypoxia and Enhances Resistance to Recurrent Hypoxia. Neurotox Res 2024; 42:13. [PMID: 38332435 DOI: 10.1007/s12640-024-00691-6] [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: 08/09/2023] [Revised: 01/09/2024] [Accepted: 01/17/2024] [Indexed: 02/10/2024]
Abstract
Hypoxia plays a significant role in the development of various cerebral diseases, many of which are associated with the potential risk of recurrence due to mitochondrial damage. Conventional drug treatments are not always effective for hypoxia-related brain diseases, necessitating the exploration of alternative compounds. In this study, we investigated the potential of diphenyl diselenide [(PhSe)2] to ameliorate locomotor impairments and mitigate brain mitochondrial dysfunction in zebrafish subjected to hypoxia. Additionally, we explored whether these improvements could confer resistance to recurrent hypoxia. Through a screening process, an appropriate dose of (PhSe)2 was determined, and animals exposed to hypoxia received a single intraperitoneal injection of 100 mg/kg of the compound or vehicle. After 1 h from the injection, evaluations were conducted on locomotor deficits, (PhSe)2 content, mitochondrial electron transport system, and mitochondrial viability in the brain. The animals were subsequently exposed to recurrent hypoxia to assess the latency time to hypoxia symptoms. The findings revealed that (PhSe)2 effectively crossed the blood-brain barrier, attenuated locomotor deficits induced by hypoxia, and improved brain mitochondrial respiration by modulating complex III. Furthermore, it enhanced mitochondrial viability in the telencephalon, contributing to greater resistance to recurrent hypoxia. These results demonstrate the beneficial effects of (PhSe)2 on both hypoxia and recurrent hypoxia, with cerebral mitochondria being a critical target of its action. Considering the involvement of brain hypoxia in numerous pathologies, (PhSe)2 should be further tested to determine its effectiveness as a potential treatment for hypoxia-related brain diseases.

Abstract
Animal models of cerebral ischemia have improved our understanding of the pathophysiology and mechanisms involved in stroke, as well as the investigation of potential therapies. The potential of zebrafish to model human diseases has become increasingly evident. The availability of these models allows for an increased understanding of the role of chemical exposure in human conditions and provides essential tools for mechanistic studies of disease. To evaluate the potential neuroprotective properties of minocycline against ischemia and reperfusion injury in zebrafish and compare them with other standardized models. In vitro studies with BV-2 cells were performed, and mammalian transient middle cerebral artery occlusion (tMCAO) was used as a comparative standard with the zebrafish stroke model. Animals were subjected to ischemia and reperfusion injury protocols and treated with minocycline. Infarction size, cytokine levels, oxidative stress, glutamate toxicity, and immunofluorescence for microglial activation, and behavioral test results were determined and compared. Administration of minocycline provided significant protection in the three stroke models in different parameters analyzed. Both experimental models complement each other in their particularities. The proposal also strengthens the findings in the literature in rodent models and allows the validation of alternative models so that they can be used in further research involving diseases with ischemia and reperfusion injury.

Abstract
INTRODUCTION The global health burden of stroke is significant and few therapeutic treatment options currently exist for patients. Pre-clinical research relies heavily on rodent stroke models but the limitations associated with using these systems alone has meant translation of drug compounds to the clinic has not been greatly successful to date. Zebrafish disease modeling offers a potentially complementary platform for pre-clinical compound screening to aid the drug discovery process for translational stroke research. AREAS COVERED In this review, the authors introduce stroke and describe the issues associated with the current pre-clinical drug development pipeline and the advantages that zebrafish disease modeling can offer. Existing zebrafish models of ischemic and hemorrhagic stroke are reviewed. Examples of how zebrafish models have been utilized for drug discovery in other disease disciplines are also discussed. EXPERT OPINION Zebrafish disease modeling holds the capacity and potential to significantly enhance the stroke drug development pipeline. However, for this system to be more widely accepted and incorporated into translational stroke research, continued improvement of the existing zebrafish stroke models, as well as focussed collaboration between zebrafish and stroke researchers, is essential.

Abstract
Understanding the molecular basis of sex differences in neural response to acute hypoxic insult has profound implications for the effective prevention and treatment of ischemic stroke. Global hypoxic-ischemic induced neural damage has been studied recently under well-controlled, non-invasive, reproducible conditions using a zebrafish model. Our earlier report on sex difference in global acute hypoxia-induced neural damage and recovery in zebrafish prompted us to conduct a comprehensive study on the mechanisms underlying the recovery. An omics approach for studying quantitative changes in brain proteome upon hypoxia insult following recovery was undertaken using iTRAQ-based LC-MS/MS approach. The results shed light on the altered expression of many regulatory proteins in the zebrafish brain upon acute hypoxia following recovery. The sex difference in differentially expressed proteins along with the proteins expressed in a uniform direction in both the sexes was studied. Core expression analysis by Ingenuity Pathway Analysis (IPA) showed a distinct sex difference in the disease function heatmap. Most of the upstream regulators obtained through IPA were validated at the transcriptional level. Translational upregulation of H3K9me3 in males led us to elucidate the mechanism of recovery by confirming transcriptional targets through ChIP-qPCR. The upregulation of H3K9me3 level in males at 4 h post-hypoxia appears to affect the early neurogenic markers nestin, klf4, and sox2, which might explain the late recovery in males, compared to females. Acute hypoxia-induced sex-specific comparison of brain proteome led us to reveal many differentially expressed proteins, which can be further studied for the development of novel targets for better therapeutic strategy.

Abstract
Cancer has become a serious disease threatening human health. To tackle this issue, developing the existing potent anticancer drugs is critical to reducing the time and cost associated with creating a new drug from scratch. Diethyldithiocarbamate (DDC) - an anticancer drug- has received considerable attention due to its selectivity and reactivity. In this study, we prepared a nanofibrous matrix from silk fibroin/polyethylene oxide loaded with diethyldithiocarbamate (DDC@SF/PEO) from an aqueous solution via an electrospinning process. Upon DDC incorporation, the nanofiber's diameter has increased from 450 nm (SF/PEO) to 1202 nm (DDC@SF/PEO) confirming the successful incorporation of DDC. Furthermore, the hydrophobicity of DDC@SF/PEO nanofibrous matrix was improved by turning SF structure from random coil (silk I) to β-sheet (silk II) through ethanol vapor treatment. Biocompatibility of DDC@SF/PEO nanofibrous matrix on human normal cells (Wi-38) showed it was safe and the apoptosis-mediated anticancer activity of DDC was enhanced. Thus, loading DDC on SF/PEO nanofibrous matrix is the key descriptor for enhanced anticancer efficacy of DDC. Considering the all-aqueous and simplistic process, the DDC@SF/PEO nanofibrous matrix could be a promising candidate for cancer treatment applications.

Abstract
Chagas disease is caused by Trypanosoma cruzi and affects thousands of people. Drugs currently used in therapy are toxic and have therapeutic limitations. In addition, the genetic diversity of T. cruzi represents an important variable and challenge in treatment. Sodium diethyldithiocarbamate (DETC) is a compound with pharmacological versatility acting as metal chelators and ROS generation. Thus, the objective was to characterize the antiparasitic action of DETC against different strains and forms of T. cruzi and their mechanism. The different strains of T. cruzi were grown in LIT medium. To evaluate the antiparasitic activity of DETC, epimastigote and trypomastigote forms of T. cruzi were used by resazurin reduction methods and by counting. Different response patterns were obtained between the strains and an IC50 of DETC ranging from 9.44 ± 3,181 to 60.49 ± 7.62 µM. Cell cytotoxicity against 3T3 and RAW cell lines and evaluated by MTT, demonstrated that DETC in high concentration (2222.00 µM) presents low toxicity. Yet, DETC causes mitochondrial damage in T. cruzi, as well as disruption in parasite membrane. DETC has antiparasitic activity against different genotypes and forms of T. cruzi, therefore, representing a promising molecule as a drug for the treatment of Chagas disease.

Abstract
Blood-brain barrier (BBB) disruption is a key event in triggering secondary damage to the central nervous system (CNS) under stroke, and is frequently associated with abnormal macroautophagy/autophagy in brain microvascular endothelial cells (BMECs). However, the underlying mechanism of autophagy in maintaining BBB integrity remains unclear. Here we report that in BMECs of patients suffering stroke, CLDN5 (claudin 5) abnormally aggregates in the cytosol accompanied by autophagy activation. In vivo zebrafish and in vitro cell studies reveal that BBB breakdown is partially caused by CAV1 (caveolin 1)-mediated redistribution of membranous CLDN5 into the cytosol under hypoxia. Meanwhile, autophagy is activated and contributes mainly to the degradation of CAV1 and aggregated CLDN5 in the cytosol of BMECs, therefore alleviating BBB breakdown. Blockage of autophagy by genetic methods or chemicals aggravates cytosolic aggregation of CLDN5, resulting in severer BBB impairment. These data demonstrate that autophagy functions in the protection of BBB integrity by regulating CLDN5 redistribution and provide a potential therapeutic strategy for BBB disorder-related cerebrovascular disease.Abbreviations: BBB: blood-brain barrier; BECN1: beclin 1; BMEC: brain microvascular endothelial cell; CAV1: caveolin 1; CCA: common carotid artery; CLDN5: claudin 5; CNS: central nervous system; CQ: chloroquine; HIF1A: hypoxia inducible factor 1 subunit alpha; MCAO: middle cerebral artery occlusion-reperfusion; OCLN: occludin; ROS: reactive oxygen species; STED: stimulated emission depletion; TEER: trans-endothelial electrical resistance; TEM: transmission electron microscopy; TJ: tight junction; TJP1: tight junction protein 1; UPS: ubiquitin-proteasome system.

Abstract
Functional recovery from hypoxia-ischemia depends on an individual's response to the ischemic damage and recovery. Many of the neurological disorders, including cerebral stroke have sex-specific characteristics. Deciphering the differential molecular mechanisms of sex-specific recovery from hypoxic-ischemic insult can improve medical practice in the treatment of cerebral stroke. In the present study, we describe the establishment of a sex-specific global hypoxia-ischemia neural damage and repair model in zebrafish. During hypoxic exposure a delayed behavioural response was observed in female fish that resumed normal swimming pattern earlier than their male counterparts. Moreover, female appeared more affected as they showed restricted locomotor and exploratory behaviour in novel tank test, reduced mitochondrial enzyme activity, enhanced DNA damage, and cell death after hypoxia insult. However, they showed a faster recovery as compared to male. Analysis of mRNA and protein expression levels of some characteristic hypoxic-ischemic markers showed notable sex-specific differences. Using zebrafish model, we have uncovered cellular and molecular differences in sex-specific systemic responses during the post-hypoxia recovery. This insight might help in devising better therapeutic strategy for stroke in female patients.

Abstract
Perioperative brain ischemia and stroke are leading causes of morbidity and mortality. Brief hypoxic preconditioning is known to have protective effects against hypoxic-ischemic insult in the brain. Current studies on the neuroprotective effects of ischemic preconditioning are based on histologic findings and biomarker changes. However, studies regarding effects on memory are rare. To precondition zebrafish to hypoxia, they were exposed to a dissolved oxygen (DO) concentration of 1.0 ± 0.5 mg/L in water for 30 s. The hypoxic zebrafish were then exposed to 1.0 ± 0.5 mg/L DO until the third stage of hypoxia, for 10 min ± 30 s. Zebrafish were assessed for memory retention after the hypoxic event. Learning and memory were tested using the T-maze, which evaluates memory based on whether or not zebrafish moves to the correct target compartment. In the hypoxic preconditioning group, infarct size was reduced compared with the hypoxic-only treated zebrafish group; memory was maintained to a degree similar to that in the hypoxia-untreated group. The hypoxic-only group showed significant memory impairments. In this study, we used a hypoxic zebrafish model and assessed the effects of ischemic preconditioning not only on histological damages but also on brain function, especially memory. This study demonstrated that a brief hypoxic event has protective effects in hypoxic brain damage and helped maintain memory in zebrafish. In addition, our findings suggest that the zebrafish model is useful in rapidly assessing the effects of ischemic preconditioning on memory.

Abstract
OBJECTIVES: To investigate the role of diethyldithiocarbamate (DEDTC) in cyclophosphamide (CP)-induced nephrotoxicity in Sprague–Dawley rat. DEDTC is a known chelating agent for copper and zinc. It is also used as a thiol protecting agent, as nuclear factor kappa-light-chain-enhancer of activated B-cells inhibitor and nitric oxide synthase inhibitor. It is also reported to inhibit superoxide dismutase (SOD) both in vitro and in vivo conditions. Considering this wide range of actions, current study investigated the role of DEDTC in CP-induced nephrotoxicity in experimental rat model. MATERIALS AND METHODS: Thirty-two male rats were randomized into four groups. Group 1, control received only saline ip; Group 2 and 4, received CP at the dose of 150 mg/kg body weight ip on the 4th day, while Group 3 and 4, received DEDTC at the dose of 250 mg/kg alternatively (fractionated dose of 1000 mg/kg). All the experimental animals were sacrificed on the 7th day and organs of interest were collected for biochemical, histopathological, DNA damage, and immunohistochemical assessments. RESULTS: DEDTC administration was found to further exacerbate the condition of CP-induced kidney damage as assessed by several biochemical and histological parameters. Further, the damage was also significantly reflected in the bladder in DEDTC-treated animals as compared to controls. SOD1 (Cu/Zn- dependent enzyme) expression was found to be decreased and this might be due to the action of DEDTC on SOD and other antioxidants. CONCLUSION: The present study indicates that DEDTC administration further exacerbated the CP-induced kidney damage in rat.

Abstract
This review by Conrad et al. reviews the functions and regulation of lipid peroxidation, ferroptosis, and the antioxidant network in diverse species, including humans, other mammals and vertebrates, plants, invertebrates, yeast, bacteria, and archaea, and discusses the potential evolutionary roles of lipid peroxidation and ferroptosis. Lipid peroxidation is the process by which oxygen combines with lipids to generate lipid hydroperoxides via intermediate formation of peroxyl radicals. Vitamin E and coenzyme Q10 react with peroxyl radicals to yield peroxides, and then these oxidized lipid species can be detoxified by glutathione and glutathione peroxidase 4 (GPX4) and other components of the cellular antioxidant defense network. Ferroptosis is a form of regulated nonapoptotic cell death involving overwhelming iron-dependent lipid peroxidation. Here, we review the functions and regulation of lipid peroxidation, ferroptosis, and the antioxidant network in diverse species, including humans, other mammals and vertebrates, plants, invertebrates, yeast, bacteria, and archaea. We also discuss the potential evolutionary roles of lipid peroxidation and ferroptosis.

Hypoxia-Induced Neuroinflammation and Learning-Memory Impairments in Adult Zebrafish Are Suppressed by Glucosamine. Mol Neurobiol 2018; 55:8738-8753. [PMID: 29589284 DOI: 10.1007/s12035-018-1017-9] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2017] [Accepted: 03/16/2018] [Indexed: 10/17/2022]
Abstract
This study investigated changes in neuroinflammation and cognitive function in adult zebrafish exposed to acute hypoxia and protective effects of glucosamine (GlcN) against hypoxia-induced brain damage. The survival rate of zebrafish following exposure to hypoxia was improved by GlcN pretreatment. Moreover, hypoxia-induced upregulation of neuroglobin, NOS2α, glial fibrillary acidic protein, and S100β in zebrafish was suppressed by GlcN. Hypoxia stimulated cell proliferation in the telencephalic ventral domain and in cerebellum subregions. GlcN decreased the number of bromodeoxyuridine (BrdU)-positive cells in the telencephalon region, but not in cerebellum regions. Transient motor neuron defects, assessed by measuring the locomotor and exploratory activity of zebrafish exposed to hypoxia recovered quickly. GlcN did not affect hypoxia-induced motor activity changes. In passive avoidance tests, hypoxia impaired learning and memory ability, deficits that were rescued by GlcN. A learning stimulus increased the nuclear translocation of phosphorylated cAMP response element binding protein (p-CREB), an effect that was greatly inhibited by hypoxia. GlcN restored nuclear p-CREB after a learning trial in hypoxia-exposed zebrafish. The neurotransmitters, γ-aminobutyric acid and glutamate, were increased after hypoxia in the zebrafish brain, and GlcN further increased their levels. In contrast, acetylcholine levels were reduced by hypoxia and restored by GlcN. Acetylcholinesterase inhibitor physostigmine partially reversed the impaired learning and memory of hypoxic zebrafish. This study represents the first examination of the molecular mechanisms underlying hypoxia-induced memory and learning defects in a zebrafish model. Our results further suggest that GlcN-associated hexosamine metabolic pathway could be an important therapeutic target for hypoxic brain damage.

Abstract
Liver cancer is mainly originated by cancer stem cells (CSCs). Due to difference in pH between normal and tumor cell microenvironments, targeting hepatic CSCs exploiting pH-dependent charge switchable nanoparticles (NPs) is extremely required to limit nonselective toxicity to normal hepatocytes (NHCs) and to completely eliminate the root of cancer origin. In this study, NPs were prepared from cationic chitosan and then coated with anionic albumin namely uncoated and coated NPs, respectively. Both NPs were loaded with diethyldithiocarbamate (DDC) which is an inhibitor of the critical enzyme, aldehyde dehydrogenase (ALDH) 1A1, for CSCs survival. The charge switchable of coated DDC-loaded NPs in neutral and acidic pH (−19 and +28.5 mv, respectively) was illustrated. This special privilege of coated NPs mediated DDC releasing in a slightly acidic pH (tumor microenvironment) rather than a neutral pH (microenvironment of normal cells). Thence, these coated NPs showed the highest selective apoptosis-mediated toxicity only in murine hepatoma cells (Hepa) that may attribute to suppression of NF-κB expression and ALDH1A1 activity, subsequently collapsing 89.7% CD133+CSCs. These new findings declare that coated NPs could be promising safe selective anticancer drug for targeting hepatic CSCs and that requires additional future investigations using animal models of liver cancer.
