Abstract
This study was dedicated to investigating the effects of microRNA-128-3p (miR-128-3p) on neuronal apoptosis and neurobehavior in cerebral palsy (CP) rats via the Smurf2/YY1 axis.In vivo modeling of hypoxic-ischemic (HI) CP was established in neonatal rats. Neurobehavioral tests (geotaxis reflex, cliff avoidance reaction, and grip test) were measured after HI induction. The HI-induced neurological injury was evaluated by HE staining, Nissl staining, TUNEL staining, immunohistochemical staining, and RT-qPCR. The expression of miR-128-3p, Smurf2, and YY1 was determined by RT-qPCR and western blot techniques. Moreover, primary cortical neurons were used to establish the oxygen and glucose deprivation (OGD) model in vitro, cell viability was detected by CCK-8 assay, neuronal apoptosis was assessed by flow cytometry and western blot, and the underlying mechanism between miR-128-3p, Smurf2 and YY1 was verified by bioinformatics analysis, dual luciferase reporter assay, RIP, Co-IP, ubiquitination assay, western blot, and RT-qPCR.In vivo, miR-128-3p and YY1 expression was elevated, and Smurf2 expression was decreased in brain tissues of hypoxic-ischemic CP rats. Downregulation of miR-128-3p or overexpression of Smurf2 improved neurobehavioral performance, reduced neuronal apoptosis, and elevated Nestin and NGF expression in hypoxic-ischemic CP rats, and downregulation of Smurf2 reversed the effects of downregulation of miR-128-3p on neurobehavioral performance, neuronal apoptosis, and Nestin and NGF expression in hypoxic-ischemic CP rats, while overexpression of YY1 reversed the effects of Smurf2 on neurobehavioral performance, neuronal apoptosis, and Nestin and NGF expression in hypoxic-ischemic CP rats. In vitro, downregulation of miR-128-3p effectively promoted the neuronal survival, reduced the apoptosis rate, and decreased caspase3 protein expression after OGD, and overexpression of YY1 reversed the ameliorative effect of downregulation of miR-128-3p on OGD-induced neuronal injury. miR-128-3p targeted to suppress Smurf2 to lower YY1 ubiquitination degradation and decrease its expression.Inhibition of miR-128-3p improves neuronal apoptosis and neurobehavioral changes in hypoxic-ischemic CP rats by promoting Smurf2 to promote YY1 ubiquitination degradation and reduce YY1 expression.

[PMID: 39068606 DOI: 10.1007/s11033-024-09822-w] [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: 05/14/2024] [Accepted: 07/23/2024] [Indexed: 07/30/2024]
Abstract
MicroRNAs (miRNAs/ miRs) are short, noncoding RNAs, usually consisting of 18 to 24 nucleotides, that control gene expression after the process of transcription and have crucial roles in several clinical processes. This article seeks to provide an in-depth review and evaluation of the many activities of miR-128, accentuating its potential as a versatile biomarker and target for therapy; The circulating miR-128 has garnered interest because of its substantial influence on gene regulation and its simplicity in extraction. Several miRNAs, such as miR-128, have been extracted from circulating blood cells, cerebrospinal fluid, and plasma/serum. The miR-128 molecule can specifically target a diverse range of genes, enabling it to have intricate physiological impacts by concurrently regulating many interrelated pathways. It has a vital function in several biological processes, such as modulating the immune system, regulating brain plasticity, organizing the cytoskeleton, and inducing neuronal death. In addition, miR-128 modulates genes associated with cell proliferation, the cell cycle, apoptosis, plasma LDL levels, and gene expression regulation in cardiac development. The dysregulation of miR-128 expression and activity is associated with the development of immunological responses, changes in neural plasticity, programmed cell death, cholesterol metabolism, and heightened vulnerability to autoimmune illnesses, neuroimmune disorders, cancer, and cardiac problems; The paper highlights the importance of studying the consequences of miR-128 dysregulation in these specific locations. By examining the implications of miRNA-128 dysregulation in these areas, the article underscores its significance in diagnosis and treatment, providing a foundation for research and clinical applications.

[PMID: 36039693 DOI: 10.1080/00207454.2022.2118598] [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: 05/24/2022] [Revised: 07/27/2022] [Accepted: 08/22/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND The regulatory potency of circular RNA (circRNA) has been acknowledged in multiple human diseases, including ischaemic stroke (IS). However, only a few circRNAs were investigated in this disorder. We aimed to uncover the role of circ_0001360 in cell models of IS in vitro. METHODS SK-N-SH cells were subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) to simulate IS pathology conditions in vitro. Quantitative real-time PCR (qPCR) and western blot were applied for expression detection. Cell viability, proliferation and apoptosis were investigated by CCK-8, EdU and flow cytometry assays. The predicted binding of miR-671-5p to circ_0001360 or BMF 3'UTR was validated by dual-luciferase reporter and RIP assays. Proteins on the NF-κB pathway were quantified by western blot to assess NF-κB pathway activity. RESULTS Circ_0001360 was upregulated in SK-N-SH cells after OGD/R treatment. OGD/R provoked SK-N-SH cell growth impairment, apoptosis and inflammation, while circ_0001360 knockdown relieved these injuries. Circ_0001360 targeted miR-671-5p, and miR-671-5p deficiency recovered SK-N-SH cell injury that was repressed by circ_0001360 knockdown. MiR-671-5p directly combined with BMF and repressed BMF expression. Accordingly, circ_0001360 targeted miR-671-5p to regulate the expression of BMF. Circ_0001360 knockdown weakened the phosphorylated levels of P65 and IκBα, while further miR-671-5p deficiency or BMF overexpression restored their expression levels. CONCLUSION Circ_0001360 contributed to OGD/R-caused SK-N-SH cell injury via targeting the miR-671-5p/BMF network and activating the NF-κB pathway, thus participating in the development of IS.

Abstract
Stroke, resulting in hypoxia and glucose deprivation, is a leading cause of death and disability worldwide. Presently, there are no treatments that reduce neuronal damage and preserve function aside from tissue plasminogen activator administration and rehabilitation therapy. Interestingly, Drosophila melanogaster, the common fruit fly, demonstrates robust hypoxic tolerance, characterized by minimal effects on survival and motor function following systemic hypoxia. Due to its organized brain, conserved neurotransmitter systems, and genetic similarity to humans and other mammals, uncovering the mechanisms of Drosophila's tolerance could be a promising approach for the development of new therapeutics. Interestingly, a key facet of hypoxic tolerance in Drosophila is organism-wide metabolic suppression, a response involving multiple genes and pathways. Specifically, studies have demonstrated that pathways associated with oxidative stress, insulin, hypoxia-inducible factors, NFκB, Wnt, Hippo, and Notch, all potentially contribute to Drosophila hypoxic tolerance. While manipulating the oxidative stress response and insulin signaling pathway has similar outcomes in Drosophila hypoxia and the mammalian middle cerebral artery occlusion (MCAO) model of ischemia, effects of Notch pathway manipulation differ between Drosophila and mammals. Additional research is warranted to further explore how other pathways implicated in hypoxic tolerance in Drosophila, such as NFκB, and Hippo, may be utilized to benefit mammalian response to ischemia. Together, these studies demonstrate that exploration of the hypoxic response in Drosophila may lead to new avenues of research for stroke treatment in humans.

Abstract
Few have characterized miRNA expression during the transition from injury to neural repair and secondary neurodegeneration following stroke in humans. We compared expression of 754 miRNAs from plasma samples collected 5, 15, and 30 days post-ischemic stroke from a discovery cohort (n = 55) and 15-days post-ischemic stroke from a validation cohort (n = 48) to healthy control samples (n = 55 and 48 respectively) matched for age, sex, race and cardiovascular comorbidities using qRT-PCR. Eight miRNAs remained significantly altered across all time points in both cohorts including many described in acute stroke. The number of significantly dysregulated miRNAs more than doubled from post-stroke day 5 (19 miRNAs) to days 15 (50 miRNAs) and 30 (57 miRNAs). Twelve brain-enriched miRNAs were significantly altered at one or more time points (decreased expression, stroke versus controls: miR-107; increased expression: miR-99-5p, miR-127-3p, miR-128-3p, miR-181a-3p, miR-181a-5p, miR-382-5p, miR-433-3p, miR-491-5p, miR-495-3p, miR-874-3p, and miR-941). Many brain-enriched miRNAs were associated with apoptosis over the first month post-stroke whereas other miRNAs suggested a transition to synapse regulation and neuronal protection by day 30. These findings suggest that a program of decreased cellular proliferation may last at least 30 days post-stroke, and points to specific miRNAs that could contribute to neural repair in humans.

Abstract
Altered expression of multiple miRNAs was found to be extensively involved in the pathogenesis of different neurological disorders including Alzheimer's disease, Parkinson's disease, stroke, epilepsy, multiple sclerosis, amyotrophic lateral sclerosis, and Huntington's disease. One of the biggest concerns within gene-based therapy is the delivery of the therapeutic microRNAs to the intended place, which is obligated to surpass the biological barriers without undergoing degradation in the bloodstream or renal excretion. Hence, the delivery of modified and unmodified miRNA molecules using excellent vehicles is required. In this light, mesenchymal stem cells (MSCs) have attracted increasing attention. The MSCs can be genetically modified to express or overexpress a particular microRNA aimed with promote neurogenesis and neuroprotection. The current review has focused on the therapeutic capabilities of microRNAs-overexpressing MSCs to ameliorate functional deficits in neurological conditions.

Abstract
OBJECTIVE Ischaemic stroke has a high death rate and frequently results in long-term and severe brain damage in survivors. miRNA-124-3p (miR-124-3p) treatment has been suggested to reduce ischaemia and play a vital function in avoiding neuron death. An investigation of the role of miR-124-3p, in the ischaemia damage repair or protection in the middle cerebral artery occlusion (MCAO) model and oxygen-glucose deprivation/reperfusion (OGD/R) model, was the purpose of this research. METHODS The expression of miRNA and mRNA in the MCAO model was predicted using bioinformatics analysis. The OGD/R neuronal model was developed. We examined the influence of a number of compounds on the OGD/R model in vitro using gain- and loss-of-function approaches. RESULTS For starters, miR-124-3p and Nrep level in the MCAO model were found to be lower in the model predicted by bioinformatics than in the sham-operated group. And then in the OGD/R model, miR-124-3p treatment reduced OGD/R neuronal damage, increased neuronal survival, and reduced apoptosis in cell lines. Moreover, we further looked at the impact of miR-124-3p on downstream Rnf38 and Nrep using the OGD/R model. Western blot analysis and dual-luciferase reporter assays indicated that miR-124-3p binds and inhibits Rnf38. Finally, although Nrep expression was reduced in the OGD/R model neuronal model, it was shown that miR-124-3p administration reduced apoptosis and increased neuronal activity, particularly with regard to axon regeneration-related proteins. CONCLUSION Our studies have shown that miR-124-3p may reduce neuronal injury by preventing Rnf38-mediated effects on the Nrep axis.

Abstract
Introduction Hypoxia-ischemia (HI) remains the leading cause of cerebral palsy and long-term neurological sequelae in infants. Despite intensive research and many therapeutic approaches, there are limited neuroprotective strategies against HI insults. Herein, we reported that HI insult significantly down-regulated microRNA-9-5p (miR-9-5p) level in the ipsilateral cortex of neonatal mice. Methods The biological function and expression patterns of protein in the ischemic hemispheres were evaluated by qRT-PCR, Western Blotting analysis, Immunofluorescence and Immunohistochemistry. Open field test and Y-maze test were applied to detect locomotor activity and exploratory behavior and working memory. Results Overexpression of miR-9-5p effectively alleviated brain injury and improved neurological behaviors following HI insult, accompanying with suppressed neuroinflammation and apoptosis. MiR-9-5p directly bound to the 3' untranslated region of DNA damage-inducible transcript 4 (DDIT4) and negatively regulated its expression. Furthermore, miR-9-5p mimics treatment down-regulated light chain 3 II/light chain 3 I (LC3 II/LC3 I) ratio and Beclin-1 expression and decreased LC3B accumulation in the ipsilateral cortex. Further analysis showed that DDIT4 knockdown conspicuously inhibited the HI-up-regulated LC3 II/ LC3 I ratio and Beclin-1 expression, associating with attenuated brain damage. Conclusion The study indicates that miR-9-5p-mediated HI injury is regulated by DDIT4-mediated autophagy pathway and up-regulation of miR-9-5p level may provide a potential therapeutic effect on HI brain damage.

Abstract
Background: Acute ischemic stroke (AIS) is the second leading cause of death and the third leading cause of disability worldwide. Long noncoding RNAs (lncRNAs) are promising biomarkers for the early diagnosis of AIS and closely participate in the mechanism of stroke onset. However, studies focusing on lncRNAs functioning as microRNA (miRNA) sponges to regulate the mRNA expression are rare and superficial. Methods: In this study, we systematically analyzed the expression profiles of lncRNA, mRNA (GSE58294), and miRNA (GSE110993) from the GEO database. Gene ontology (GO) analysis was performed to reveal the functions of differentially expressed genes (DEGs), and we used weighted gene co-expression network analysis (WGCNA) to investigate the relationships between clinical features and expression profiles and the co-expression of miRNA and lncRNA. Finally, we constructed a lncRNA-miRNA-mRNA competing endogenous RNA (ceRNA) network with selected DEGs using bioinformatics methods and obtained ROC curves to assess the diagnostic efficacy of differentially expressed lncRNAs (DElncRNAs) and differentially expressed mRNAs (DEmRNAs) in our network. The GSE22255 dataset was used to confirm the diagnostic value of candidate genes. Results: In total, 199 DElncRNAs, 2068 DEmRNAs, and 96 differentially expressed miRNAs were detected. The GO analysis revealed that DEmRNAs primarily participate in neutrophil activation, neutrophil degranulation, vacuolar transport, and lysosomal transport. WGCNA screened out 16 lncRNAs and 195 mRNAs from DEGs, and only eight DElncRNAs maintained an area under the curve higher than 0.9. By investigating the relationships between lncRNAs and mRNAs, a ceRNA network containing three lncRNAs, three miRNAs, and seven mRNAs was constructed. GSE22255 confirmed that RP1-193H18.2 is more advantageous for diagnosing stroke, whereas no mRNA showed realistic diagnostic efficacy. Conclusion: The ceRNA network may broaden our understanding of AIS pathology, and the candidate lncRNA from the ceRNA network is assumed to be a promising therapeutic target and diagnostic biomarker for AIS.

Long non-coding RNA MIAT impairs neurological function in ischemic stroke via up-regulating microRNA-874-3p-targeted IL1B. Brain Res Bull 2021; 175:81-89. [PMID: 34265390 DOI: 10.1016/j.brainresbull.2021.07.005] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 07/02/2021] [Accepted: 07/08/2021] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) have diagnostic and therapeutic values in the setting of ischemic stroke (IS). Here, we evaluated the value of myocardial infarction-associated transcript (MIAT) in IS with the involvement of microRNA (miR)-874-3p/interleukin (IL) 1B. METHODS MIAT, miR-874-3p and IL1B levels in serum of patients with IS were measured. A middle cerebral artery occlusion (MCAO) model was established in mice. MCAO mice were injected with Agomir of miR-874-3p, shRNA or overexpression vector of MIAT or siRNA of IL1B. Subsequently, behavioral activities and neurological function of mice were assessed. The number of Nissl bodies, brain damage, neuronal apoptosis and inflammatory factors in brain tissues of mice were measured. The targeting relationship between MIAT and miR-874-3p, as well as that between miR-874-3p and IL1B was explored. RESULTS In patients with IS, MIAT and IL1B were up-regulated and miR-874-3p was down-regulated. MIAT absorbed miR-874-3p while miR-874-3p targeted IL1B. Silencing of MIAT or IL1B, or promotion of miR-874-3p improved behavioral activities and neurological function of mice, reduced the number of Nissl bodies, as well as improved brain damage, neuronal apoptosis and inflammation. Overexpression of miR-874-3p abrogated up-regulated MIAT-mediated influence on MCAO mice. CONCLUSION Shortly, this study figures out that MIAT impairs neurological function in IS via up-regulating miR-874-3p-targeted IL1B.

Abstract
OBJECTIVE Stroke is a cerebrovascular disorder that often causes neurological function defects. ARPP21 is a conserved host gene of miR-128 controlling neurodevelopmental functions. This study investigated the mechanism of ARPP21 antagonistic intron miR-128 on neurological function repair after stroke. METHODS Expressions of ARPP21 and miR-128 in stroke patients were detected. The mouse neurons and astrocytes were cultured in vitro and treated with oxygen-glucose deprivation (OGD). The OGD-treated cells were transfected with pc-ARPP21 and miR-128 mimic. The proliferation of astrocytes, and the apoptosis of neurons and astrocytes were detected, and inflammatory factors of astrocytes were measured. The binding relationship between miR-128 and CREB1 was verified. The rat model of middle cerebral artery occlusion (MCAO) was established. ARPP21 expression in model rats was detected. The effects of pc-ARPP21 on neuron injury, brain edema volume, and cerebral infarct in rats were observed. RESULTS ARPP21 expression was downregulated and miR-128 expression was upregulated in stroke patients. pc-ARPP21 facilitated the proliferation of astrocytes and inhibited apoptosis of neurons and astrocytes, and reduced inflammation of astrocytes. miR-128 mimic could reverse these effects of pc-ARPP21 on neurons and astrocytes. miR-128 targeted CREB1 and reduced BDNF secretion. In vitro experiments confirmed that ARPP21 expression was decreased in MCAO rats, and pc-ARPP21 promoted neurological function repair after stroke. CONCLUSION ARPP21 upregulated CREB1 and BDNF expressions by antagonizing miR-128, thus inhibiting neuronal apoptosis and promoting neurological function repair after stroke. This study may offer a novel target for the management of stroke.

Abstract
BACKGROUND Ischemic stroke induces neuronal cell death and causes brain dysfunction. Preventing neuronal cell death after stroke is key to protecting the brain from stroke damage. Nevertheless, preventative measures and treatment strategies for stroke damage are scarce. Emerging evidence suggests that microRNAs (miRNAs) play critical roles in the pathogenesis of central nervous system (CNS) disorders and may serve as potential therapeutic targets. METHODS A photochemically induced thrombosis (PIT) mouse model was used as an ischemic stroke model. qRT-PCR was employed to assess changes in miRNAs in ischemic lesions of PIT-stroke mice and primary cultured neurons subjected to oxygen-glucose deprivation (OGD). 2,3,5-triphenyltetrazolium chloride (TTC) staining was performed to evaluate brain infarction tissues in vivo. TUNEL staining was employed to assess neuronal death in vitro. Neurological scores and motor coordination were investigated to evaluate stroke damage, including neurological deficits and motor function. RESULTS In vivo and in vitro results demonstrated that levels of miR-124 were significantly decreased following stroke, whereas changes in death-associated protein kinase 1 (DAPK1) levels exhibited the converse pattern. DAPK1 was identified as a direct target of miR-124. N-methyl-D-aspartate (NMDA) and OGD-induced neuronal death was rescued by miR-124 overexpression. Upregulation of miR-124 levels significantly improved PIT-stroke damage, including the overall neurological function in mice. CONCLUSION We demonstrate the involvement of the miR-124/DAPK1 pathway in ischemic neuronal death. Our results highlight the therapeutic potential of targeting this pathway for ischemic stroke.

[PMID: 34730612 PMCID: PMC8527554 DOI: 10.6061/clinics/2021/e2958] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 08/16/2021] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVES To investigate the clinical utility of serum microRNA levels (miR-9-5p and miR-128-3p) in the diagnosis and prognosis of early-stage acute ischemic stroke (AIS). METHODS We compared the differences in serum miR-9-5p and miR-128-3p levels between patients with AIS and healthy individuals (controls). The serum levels of miR-9-5p and miR-128-3p were quantified using quantitative real-time PCR, and the association of each miRNA with AIS was determined using receiver operator characteristic curve analysis. The predictive value of these indices in the diagnosis of early-stage AIS was evaluated in conjunction with that of computed tomography findings and neuron-specific enolase levels. The prognosis of patients with AIS was evaluated three months after their discharge from hospital using the modified Rankin scale, which classifies the prognosis as either favorable or poor. Logistic regression analysis was used to analyze the correlation between miR-9-5p and miR-128-3p levels and patient prognosis. RESULTS The serum levels of miR-9-5p and miR-128-3p were upregulated in patients with AIS relative to those in healthy individuals. A pronounced correlation was identified between serum miR-9-5p and miR-128-3p levels and patient prognosis, with high levels of both miRNAs being associated with poor patient outcomes. CONCLUSION Assessment of serum miR-9-5p and miR-128-3p levels is important for the early diagnosis and prognosis of AIS.

Neuropsychiatr Dis Treat 2021; 17:1989-2002. [PMID: 34177264 PMCID: PMC8219303 DOI: 10.2147/ndt.s290237] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 04/27/2021] [Indexed: 12/25/2022] Open
Abstract
PURPOSE MicroRNAs (miRNAs) are emerging as essential regulators in the development of cerebral ischemia/reperfusion (I/R) injury. This study aimed to explore the regulation of miR-9-3p on FGF19-GSK-3β/Nrf2/ARE signaling in cerebral I/R injury. MATERIALS AND METHODS A mouse model with I/R injury was constructed by middle cerebral artery occlusion (MCAO) and an HT22 cell model was established by oxygen-glucose deprivation/reperfusion (OGD/R). The expression of miR-9-3p was detected by RT-qPCR. Protein expression of fibroblast growth factor 19 (FGF19), cleaved caspase-3, and GSK-3β signaling-related proteins (p-GSK-3β and Nrf2) were detected by Western blot. Cell viability was assessed by MTT assay. Oxidative stress was detected by commercial kits. The target of miR-9-3p was predicted by TargetScan and confirmed by luciferase reporter assay. The effects of miR-9-3p on GSK-3β/Nrf2/ARE signaling were assessed by rescue experiments. RESULTS MiR-9-3p was significantly upregulated in brain tissues of MCAO/R-treated mice and OGD/R-treated HT22 cells. Downregulation of miR-9-3p attenuated infarct volume and neurological outcomes of MCAO/R-treated mice in vivo and OGD/R-induced cell injury and oxidative stress in vitro, while overexpression of miR-9-3p showed the opposite effects. MiR-9-3p directly bound to the 3'-untranslated region of FGF19 and negatively regulated its expression. Inhibition of miR-9-3p enhanced GSK-3β/Nrf2/ARE signaling-mediated antioxidant response, while this effect was partially eliminated by FGF19 or Nrf2 silencing. CONCLUSION Our study suggests that inhibition of miR-9-3p protects against cerebral I/R injury through activating GSK-3β/Nrf2/ARE signaling-mediated antioxidant responses by targeting FGF19, providing a potential therapeutic target for ischemic stroke.
