[PMID: 38767481 PMCID: PMC11246127 DOI: 10.4103/nrr.nrr-d-23-01292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/09/2023] [Accepted: 12/18/2023] [Indexed: 05/22/2024] Open
Abstract
Acute ischemic stroke is a clinical emergency and a condition with high morbidity, mortality, and disability. Accurate predictive, diagnostic, and prognostic biomarkers and effective therapeutic targets for acute ischemic stroke remain undetermined. With innovations in high-throughput gene sequencing analysis, many aberrantly expressed non-coding RNAs (ncRNAs) in the brain and peripheral blood after acute ischemic stroke have been found in clinical samples and experimental models. Differentially expressed ncRNAs in the post-stroke brain were demonstrated to play vital roles in pathological processes, leading to neuroprotection or deterioration, thus ncRNAs can serve as therapeutic targets in acute ischemic stroke. Moreover, distinctly expressed ncRNAs in the peripheral blood can be used as biomarkers for acute ischemic stroke prediction, diagnosis, and prognosis. In particular, ncRNAs in peripheral immune cells were recently shown to be involved in the peripheral and brain immune response after acute ischemic stroke. In this review, we consolidate the latest progress of research into the roles of ncRNAs (microRNAs, long ncRNAs, and circular RNAs) in the pathological processes of acute ischemic stroke-induced brain damage, as well as the potential of these ncRNAs to act as biomarkers for acute ischemic stroke prediction, diagnosis, and prognosis. Findings from this review will provide novel ideas for the clinical application of ncRNAs in acute ischemic stroke.

Transcriptomic analysis reveals molecular characterization and immune landscape of PANoptosis-related genes in atherosclerosis. Inflamm Res 2024; 73:961-978. [PMID: 38587531 DOI: 10.1007/s00011-024-01877-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 03/01/2024] [Accepted: 03/27/2024] [Indexed: 04/09/2024] Open
Abstract
BACKGROUND Atherosclerosis is a chronic inflammatory disease characterized by abnormal lipid deposition in the arteries. Programmed cell death is involved in the inflammatory response of atherosclerosis, but PANoptosis, as a new form of programmed cell death, is still unclear in atherosclerosis. This study explored the key PANoptosis-related genes involved in atherosclerosis and their potential mechanisms through bioinformatics analysis. METHODS We evaluated differentially expressed genes (DEGs) and immune infiltration landscape in atherosclerosis using microarray datasets and bioinformatics analysis. By intersecting PANoptosis-related genes from the GeneCards database with DEGs, we obtained a set of PANoptosis-related genes in atherosclerosis (PANoDEGs). Functional enrichment analysis of PANoDEGs was performed and protein-protein interaction (PPI) network of PANoDEGs was established. The machine learning algorithms were used to identify the key PANoDEGs closely linked to atherosclerosis. Receiver operating characteristic (ROC) analysis was used to assess the diagnostic potency of key PANoDEGs. CIBERSORT was used to analyze the immune infiltration patterns in atherosclerosis, and the Spearman method was used to study the relationship between key PANoDEGs and immune infiltration abundance. The single gene enrichment analysis of key PANoDEGs was investigated by GSEA. The transcription factors and target miRNAs of key PANoDEGs were predicted by Cytoscape and online database, respectively. The expression of key PANoDEGs was validated through animal and cell experiments. RESULTS PANoDEGs in atherosclerosis were significantly enriched in apoptotic process, pyroptosis, necroptosis, cytosolic DNA-sensing pathway, NOD-like receptor signaling pathway, lipid and atherosclerosis. Four key PANoDEGs (ZBP1, SNHG6, DNM1L, and AIM2) were found to be closely related to atherosclerosis. The ROC curve analysis demonstrated that the key PANoDEGs had a strong diagnostic potential in distinguishing atherosclerotic samples from control samples. Immune cell infiltration analysis revealed that the proportion of initial B cells, plasma cells, CD4 memory resting T cells, and M1 macrophages was significantly higher in atherosclerotic tissues compared to normal tissues. Spearman analysis showed that key PANoDEGs showed strong correlations with immune cells such as T cells, macrophages, plasma cells, and mast cells. The regulatory networks of the four key PANoDEGs were established. The expression of key PANoDEGs was verified in further cell and animal experiments. CONCLUSIONS This study evaluated the expression changes of PANoptosis-related genes in atherosclerosis, providing a reference direction for the study of PANoptosis in atherosclerosis and offering potential new avenues for further understanding the pathogenesis and treatment strategies of atherosclerosis.

ENVIRONMENTAL TOXICOLOGY 2024; 39:2634-2641. [PMID: 38205902 DOI: 10.1002/tox.24132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 12/07/2023] [Accepted: 12/25/2023] [Indexed: 01/12/2024]
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a widespread inflammatory disease with a high mortality rate. Long noncoding RNAs play important roles in pulmonary diseases and are potential targets for inflammation intervention. METHODS The expression of small nucleolar RNA host gene 6 (SNHG6) in mouse lung epithelial cell line MLE12 with or without cigarette smoke extract (CSE) treatment was first detected using quantitative reverse-transcription PCR. ELISA was used to evaluate the release of inflammatory cytokines (TNF-α, IL-1β, and IL-6). The binding site of miR-182-5p with SNHG6 was predicted by using miRanda, which was verified by double luciferase reporter assay. RESULTS Here, we revealed that SNHG6 was upregulated in CS-exposed MLE12 alveolar epithelial cells and lungs from COPD-model mice. SNHG6 silencing weakened CS-induced inflammation in MLE12 cells and mouse lungs. Mechanistic investigations revealed that SNHG6 could upregulate IκBα kinase through sponging the microRNA miR-182-5p, followed by activated NF-κB signaling. The suppressive effects of SNHG6 silencing on CS-induced inflammation were blocked by an miR-182-5p inhibitor. CONCLUSION Overall, our findings suggested that SNHG6 regulates CS-induced inflammation in COPD by activating NF-κB signaling, thereby offering a novel potential target for COPD treatment.

Abstract
Neuropathic pain is a widespread clinical issue caused by somatosensory nervous system damage, affecting numerous individuals. It poses considerable economic and public health challenges, and managing it can be challenging due to unclear underlying mechanisms. Nevertheless, emerging evidence suggests that neurogenic inflammation and neuroinflammation play a role in developing pain patterns. Emerging evidence suggests that neurogenic inflammation and neuroinflammation play significant roles in developing neuropathic pain within the nervous system. Increased/decreased miRNA expression patterns could affect the progression of neuropathic and inflammatory pain by controlling nerve regeneration, neuroinflammation, and the expression of abnormal ion channels. However, our limited knowledge of miRNA targets hinders a complete grasp of miRNA's functions. Meanwhile, exploring exosomal miRNA, a recently uncovered role, has significantly advanced our comprehension of neuropathic pain's pathophysiology in recent times. In this review, we present a comprehensive overview of the latest miRNA studies and explore the possible ways miRNAs might play a role in the development of neuropathic pain.

Abstract
Background Immune-related lncRNA is involved in tumor initiation and progression, while its effect in glioblastoma (GBM) is still unknown. Objective We sought to investigate the association between immune-related lncRNA (ir-lncRNA) and GBM. Methods Transcriptomic and clinical data were obtained from the TCGA dataset, and we found 2008 ir-lncRNA differentially expressed between GBM and adjacent brain tissues. Results Appling the univariate Cox and Lasso regression model, we found 30 prognosis-related ir-lncRNA pairs to construct a Cox regression risk model to associate the outcome of GBM patients. Furthermore, with this risk model, we can identify the tumor immune infiltration status, the expression of immunosuppressive biomarkers, and chemical sensitivity in GBM patients. Conclusions We constructed an immunologic risk model with lncRNA to associate the survival outcome of GBM patients, which can provide useful biomarkers.

Abstract
Neurological disorders with various etiologies impacting the nervous system are prevalent in clinical practice. Long non-coding RNA (lncRNA) molecules are functional RNA molecules exceeding 200 nucleotides in length that do not encode proteins, but participate in essential activities. Research indicates that lncRNAs may contribute to the pathogenesis of neurological disorders, and may be potential targets for their treatment. Phytochemicals in traditional Chinese herbal medicine (CHM) have been found to exert neuroprotective effects by targeting lncRNAs and regulating gene expression and various signaling pathways. We aim to establish the development status and neuroprotective mechanism of phytochemicals that target lncRNAs through a thorough literature review. A total of 369 articles were retrieved through manual and electronic searches of PubMed, Web of Science, Scopus and CNKI databases from inception to September 2022. The search utilized combinations of natural products, lncRNAs, neurological disorders, and neuroprotective effects as keywords. The included studies, a total of 31 preclinical trials, were critically reviewed to present the current situation and the progress in phytochemical-targeted lncRNAs in neuroprotection. Phytochemicals have demonstrated neuroprotective effects in preclinical studies of various neurological disorders by regulating lncRNAs. These disorders include arteriosclerotic ischemia-reperfusion injury, ischemic/hemorrhagic stroke, Alzheimer's disease, Parkinson's disease, glioma, peripheral nerve injury, post-stroke depression, and depression. Several phytochemicals exert neuroprotective roles through mechanisms such as anti-inflammatory, antioxidant, anti-apoptosis, autophagy regulation, and antagonism of Aβ-induced neurotoxicity. Some phytochemicals targeted lncRNAs and served a neuroprotective role by regulating microRNA and mRNA expression. The emergence of lncRNAs as pathological regulators provides a novel direction for the study of phytochemicals in CHM. Elucidating the mechanism of phytochemicals regulating lncRNAs will help to identify new therapeutic targets and promote their application in precision medicine.

Life Sci 2023; 313:121276. [PMID: 36496032 DOI: 10.1016/j.lfs.2022.121276] [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: 08/07/2022] [Revised: 11/29/2022] [Accepted: 12/05/2022] [Indexed: 12/12/2022]
Abstract
AIM LncRNAs are highly expressed in the CNS and regulate pathophysiological processes. However, the potential role of lncRNAs inischemic stroke (IS) remains unknown. In this study, we investigated the functions and possible molecular mechanism of lncRNA paternal expressed gene 11 antisense (PEG11as) in this process. METHODS Middle cerebral artery occlusion/reperfusion (MCAO/R) mice model and N2a cells model from oxygen-glucose deprivation/reoxygenation (OGD/R) were used to simulate cerebral I/R in vivo and in vitro. High-throughput sequencing (RNA-Seq) was used todetect differential expression of lncRNAs in cerebral I/R. QRT-PCR was used to detect the expression of PEG11as and miR-342-5p. Bioinformatics analysis, FISH, luciferase reporter assay, RIP, Western blot, and immunofluorescence were used to detect the interaction between PEG11as, miR-342-5p and PFN1. The effect on neuronal apoptosis was analyzed using loss-of-function combined with TUNEL, Hoechst, and caspase3 activity assays. KEY FINDINGS 254 lncRNAs were differentially expressed in MCAO1h/R6h mice. Among them, PEG11as was significantly up-regulated. PEG11as down-regulated could markedly attenuate the brain infarct volume, alleviate neurological deficit in vivo, and effectively promote neuron survival, attenuate neuronal apoptosis both in vivo and in vitro. FISH assay discovered that PEG11as was mainly located in the cytoplasm. Furthermore, we demonstrated that PEG11as was able to bind miR-342-5p to inhibit miR-342-5p activity, whereas the down-regulated of miR-342-5p resulted in profilin 1 (PFN1) overexpression and thus promoting apoptosis. SIGNIFICANCE This study suggests that PEG11as regulates neuronal apoptosis by miR-342-5p/PFN1 axis, which may contribute to our understanding of pathogenesis and provide a potential therapeutic option for cerebral I/R.

Abstract
Neuropathic pain, which results from damage to the somatosensory nervous system, is a global clinical condition that affects many people. Neuropathic pain imposes significant economic and public health burdens and is often difficult to manage because the underlying mechanisms remain unclear. However, mounting evidence indicates a role for neurogenic inflammation and neuroinflammation in pain pattern development. There is increasing evidence that the activation of neurogenic inflammation and neuroinflammation in the nervous system contribute to neuropathic pain. Altered miRNA expression profiles might be involved in the pathogenesis of both inflammatory and neuropathic pain by regulating neuroinflammation, nerve regeneration, and abnormal ion channel expression. However, the lack of knowledge about miRNA target genes prevents a full understanding of the biological functions of miRNAs. At the same time, an extensive study on exosomal miRNA, a newly discovered role, has advanced our understanding of the pathophysiology of neuropathic pain in recent years. This section provides a comprehensive overview of the current understanding of miRNA research and discusses the potential mechanisms of miRNAs in neuropathic pain.

Abstract
AbstractBased on clinical observations, stroke is touted as one of the specific pathological conditions, affecting an individual’s life worldwide. So far, no effective treatment has been introduced to deal with stroke post-complications. Production and release of several neurotrophic factors by different cells exert positive effects on ischemic areas following stroke. As a correlate, basic and clinical studies have focused on the development and discovery of de novo modalities to introduce these factors timely and in appropriate doses into the affected areas. Exosomes (Exo) are non-sized vesicles released from many cells during pathological and physiological conditions and participate in intercellular communication. These particles transfer several arrays of signaling molecules, like several neurotrophic factors into the acceptor cells and induce specific signaling cascades in the favor of cell bioactivity. This review aimed to highlight the emerging role of exosomes as a therapeutic approach in the regeneration of ischemic areas.

Abstract
The role of non-coding RNAs in neuropsychiatric disorders (NPDs) is an emerging field of study. The long non-coding RNAs (lncRNAs) are shown to sponge the microRNAs (miRNAs) from interacting with their target mRNAs. Investigating the sponge activity of lncRNAs in NPDs will provide further insights into biological mechanisms and help identify disease biomarkers. In this study, a large-scale inference of the lncRNA-related miRNA sponge network of pan-neuropsychiatric disorders, including autism spectrum disorder (ASD), schizophrenia (SCZ), and bipolar disorder (BD), was carried out using brain transcriptomic (RNA-Seq) data. The candidate miRNA sponge modules were identified based on the co-expression pattern of non-coding RNAs, sharing of miRNA binding sites, and sensitivity canonical correlation. miRNA sponge modules are associated with chemical synaptic transmission, nervous system development, metabolism, immune system response, ribosomes, and pathways in cancer. The identified modules showed similar and distinct gene expression patterns depending on the neuropsychiatric condition. The preservation of miRNA sponge modules was shown in the independent brain and blood-transcriptomic datasets of NPDs. We also identified miRNA sponging lncRNAs that may be potential diagnostic biomarkers for NPDs. Our study provides a comprehensive resource on miRNA sponging in NPDs.

Abstract
Background: Numerous studies have suggested that programmed cell death (PCD) pathways play vital roles in cerebral ischemia/reperfusion (I/R) injury. However, the specific mechanisms underlying cell death during cerebral I/R injury have yet to be completely clarified. There is thus a need to identify the PCD-related gene signatures and the associated regulatory axes in cerebral I/R injury, which should provide novel therapeutic targets against cerebral I/R injury. Methods: We analyzed transcriptome signatures of brain tissue samples from mice subjected to middle cerebral artery occlusion/reperfusion (MCAO/R) and matched controls, and identified differentially expressed genes related to the three types of PCD(apoptosis, pyroptosis, and necroptosis). We next performed functional enrichment analysis and constructed PCD-related competing endogenous RNA (ceRNA) regulatory networks. We also conducted hub gene analysis to identify hub nodes and key regulatory axes. Results: Fifteen PCD-related genes were identified. Functional enrichment analysis showed that they were particularly associated with corresponding PCD-related biological processes, inflammatory response, and reactive oxygen species metabolic processes. The apoptosis-related ceRNA regulatory network was constructed, which included 24 long noncoding RNAs (lncRNAs), 41 microRNAs (miRNAs), and 4 messenger RNAs (mRNAs); the necroptosis-related ceRNA regulatory network included 16 lncRNAs, 20 miRNAs, and 6 mRNAs; and the pyroptosis-related ceRNA regulatory network included 15 lncRNAs, 18 miRNAs, and 6 mRNAs. Hub gene analysis identified hub nodes in each PCD-related ceRNA regulatory network and seven key regulatory axes in total, namely, lncRNA Malat1/miR-181a-5p/Mapt, lncRNA Malat1/miR-181b-5p/Mapt, lncRNA Neat1/miR-181a-5p/Mapt, and lncRNA Neat1/miR-181b-5p/Mapt for the apoptosis-related ceRNA regulatory network; lncRNA Neat1/miR-181a-5p/Tnf for the necroptosis-related ceRNA regulatory network; lncRNA Malat1/miR-181c-5p/Tnf for the pyroptosis-related ceRNA regulatory network; and lncRNAMalat1/miR-181a-5p for both necroptosis-related and pyroptosis-related ceRNA regulatory networks. Conclusion: The results of this study supported the hypothesis that these PCD pathways (apoptosis, necroptosis, pyroptosis, and PANoptosis) and crosstalk among them might be involved in ischemic stroke and that the key nodes and regulatory axes identified in this study might play vital roles in regulating the above processes. This may offer new insights into the potential mechanisms underlying cell death during cerebral I/R injury and provide new therapeutic targets for neuroprotection.

Abstract
Glioblastoma (GBM) is the most malignant form of brain cancer in the world. Nevertheless, the survival rate of patients with GBM is extremely low. N6-methyladenosine (m6A) and long noncoding RNAs (lncRNAs) conduct important biological functions in patients’ survival status and the immunotherapeutic response. Here, m6A-related lncRNAs were identified by a co-expression method. Univariate and multivariate Cox regression together with LASSO were applied to establish the risk model. Kaplan-Meier and ROC analysis were applied to evaluate the prediction power of this risk model. Finally, the related immune profiling and chemical sensitivity targets were also investigated. The risk model holding three m6A-related lncRNAs was confirmed as an independent predictor for the prognosis. Furthermore, we found the risk model based on m6A-related lncRNAs is associated with the immune status, immunosuppressive biomarkers, and chemo-sensitivity in GBM patients. The RP11-552D4.1 is found to facilitate neuronal proliferation. This risk model consisted of m6A-related lncRNAs may be available for the clinical interventions in GBM patients.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) is a common chronic lung disease in premature infants, and its pathogenesis has not been clarified. Long non-coding RNAs (lncRNA) have important functions in cell bioactivity. However, their role in developmental lung disease remains unclear. OBJECTIVE The aim of this study was to demonstrate the role of lncRNA SNHG6 (SNHG6) in BPD and its underlying mechanisms. METHODS The blood of patients with BPD were collected, and BPD model of BEAS-2B cells was established by hyperoxia method. SNHG6, miR-335 and KLF5 mRNA expression were detected by RT-qPCR. Western blot was conducted to measure the levels of apoptosis-related proteins' expression and NF-κB pathway related proteins. BEAS-2B cell viability and apoptosis were assessed by CCK-8 and flow cytometry, respectively. Assay Kit was applied to detect ROS, MDA and SOD levels, respectively. ELISA was performed to assess the levels of inflammatory factors. The binding site of miR-335 with SNHG6 or KLF5 were predicted by using DIANA or TargetScan, and which was verified by double luciferase reporter assay. RESULTS Firstly, SNHG6 was highly expressed and miR-335 was lowly expressed in BPD model, SNHG6 knockdown and miR-335 mimics both alleviated hyperoxia-induced lung cell injury, and SNHG6 targeted miR-335. Subsequently, KLF5 was targeted by miR-335, and KLF5 promoted lung cell injury via activating NF-κB pathway. Furthermore, SNHG6 mediated lung cell injury via regulating the miR-335/KLF5/NF-κB pathway. CONCLUSION Our research confirmed that SNHG6 mediated hyperoxia-induced lung cell injury via regulating the miR-335/KLF5/NF-κB pathway. These findings suggest that SNHG6 serves as promising targets for the treatment of newborns with BPD.

Abstract
BACKGROUND Bipolar disorder (BD) is a multifactorial condition. Several signaling pathways affect development of this disorder. With the purpose of exploring the role of vitamin D receptor (VDR) signaling in this disorder, we measured expression of selected mRNA coding genes and long non-coding RNAs (lncRNAs) in this pathway in patients versus normal subjects. METHODS We measured expression of VDR-associated lncRNAs and mRNAs (SNHG6, MALAT1, Linc00511, Linc00346, VDR and CYP27B1) in the peripheral blood of BD patients vs. healthy individuals. RESULTS Expression of SNHG6 was significantly higher in cases vs. controls (Posterior beta = 1.29, P value < 0.0001. Subgroup analysis by sex revealed significant results in both subgroups (P value < 0.0001 and P value = 0.023 for males and females, respectively). Expression of CYP27B1 was up-regulated in cases vs. controls (Posterior beta = 0.415, P < 0.0001). Such pattern was also detected among males (P < 0.0001), but not females (P = 0.419). Similarly, MALAT1 and Linc00346 were up-regulated in total cases vs. controls (Posterior beta = 0.694, P < 0.0001 and Posterior beta = 0.4, P = 0.012, respectively) and in male cases compared with male controls (Posterior beta = 0.712, P < 0.0001 and Posterior beta = 0.41, P value = 0.038, respectively). Expression of VDR was up-regulated in total cases compared with controls (Posterior beta = 0.683, P value = 0.001). Finally, expression of Linc00511 was not different between groups. MALAT1, SNHG6, CYP27B1, VDR and Linc00346 had AUC values of 0.95, 0.94, 0.91, 0.85 and 0.83 in differentiation of male patients from controls, respectively. CONCLUSION The current study suggests VDR-associated genes as possible markers for BD.

Abstract
Ischemic stroke (IS) is a disease that is characterized by high mortality and disability. Recent studies have shown that LncRNA-mediated competing endogenous RNA (ceRNA) networks play roles in the occurrence and development of cerebral I/R injury by regulating different signaling pathways. However, no systematic analysis of ceRNA mechanisms in IS has been reported. In this review, we discuss molecular mechanisms of LncRNA-mediated ceRNA networks under I/R injury. The expression levels of LncRNAs, microRNAs (miRNAs), and messenger RNAs (mRNAs) and their effects in four major cell types of the neurovascular unit (NVU) are also involved. We further summarize studies of LncRNAs as biomarkers and therapeutic targets. Finally, we analyze the advantages and limitations of using LncRNAs as therapeutics for IS.

Abstract
Background Type II diabetes mellitus (T2DM) is an important risk factor for osseointegration of implants. The aim of this study was to explore key genes of T2DM affecting bone metabolism through bioinformatic analysis of published RNA sequencing data, identify potential biomarkers, and provide a reference for finding the molecular mechanism of abnormal osseointegration caused by T2DM. Methods We identified differentially expressed mRNAs and miRNAs from the Gene Expression Omnibus database using the R package ‘limma’ and analysed the predicted target genes using Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis and Gene Ontology analysis. At the same time, miRNA–mRNA interactions were explored using miRWalk 2.0. Results We constructed an miRNA-gene regulatory network and a protein–protein interaction network. The enrichment pathways of differentially expressed mRNAs included extracellular matrix receptor interactions, protein digestion and absorption, the PI3K-Akt signalling pathway, cytokine–cytokine receptor interactions, chemokine signalling pathways, and haematopoietic cell lineage functions. We analysed the expression of these differentially expressed mRNAs and miRNAs in T2DM rats and normal rats with bone implants and identified Smpd3, Itga10, and rno-mir-207 as possible key players in osseointegration in T2DM. Conclusion Smpd3, Itga10, and rno-mir-207 are possible biomarkers of osseointegration in T2DM. This study sheds light on the possible molecular mechanism of abnormal osseointegration caused by bone metabolism disorder in T2DM.

Abstract
Purpose Acute ischemic stroke (AIS) is a leading health problem caused by cerebral ischemia/reperfusion (CI/R). This study aimed to unveil the potential clinical value and mechanism of lncRNA CASC15. Patients and Methods The expression of CASC15, miR-338-3p was detected by quantitative real-time PCR (qRT-PCR). The correlations between CASC15 and national institutes of health stroke scale (NIHSS) scores or miR-338-3p were evaluated by Pearson correlation. A receiver operating characteristic (ROC) curve was performed to provide the diagnostic value of CASC15. Cell Counting Kit-8 (CCK-8) and flow cytometer were used to detect the condition of cell viability and apoptosis. The levels of interleukin-1beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA) assay. Results The expression of CASC15 was increased and the levels of miR-338-3p were decreased in AIS patients. A positive association between CASC15 and NIHSS score and an inverse association between CASC15 and miR-338-3p were revealed by Pearson correlation. CASC15 might discriminate AIS patients from healthy people. Silenced CASC15 exerted neuroprotective roles on cell viability, apoptosis, and inflammation via the miR-338-3p/ETS1 axis. Conclusion CASC15 might act as a potential diagnostic biomarker for AIS patients. CASC15/miR-338-3p/ETS1 axis played an essential role in cell viability, apoptosis, and neuroinflammation.

Abstract
The mammalian brain expresses several classes of noncoding RNAs (ncRNAs), including long ncRNAs (lncRNAs), circular RNAs (circRNAs), and microRNAs (miRNAs). These ncRNAs play vital roles in regulating cellular processes by RNA/protein scaffolding, sponging and epigenetic modifications during the pathophysiological conditions, thereby controlling transcription and translation. Some of these functions are the result of crosstalk between ncRNAs to form a competitive endogenous RNA network. These intricately organized networks comprise lncRNA/miRNA, circRNA/miRNA, or lncRNA/miRNA/circRNA, leading to crosstalk between coding and ncRNAs through miRNAs. The miRNA response elements predominantly mediate the ncRNA crosstalk to buffer the miRNAs and thereby fine-tune and counterbalance the genomic changes and regulate neuronal plasticity, synaptogenesis and neuronal differentiation. The perturbed levels and interactions of the ncRNAs could lead to pathologic events like apoptosis and inflammation. Although the regulatory landscape of the ncRNA crosstalk is still evolving, some well-known examples such as lncRNA Malat1 sponging miR-145, circRNA CDR1as sponging miR-7, and lncRNA Cyrano and the circRNA CDR1as regulating miR-7, has been shown to affect brain function. The ability to manipulate these networks is crucial in determining the functional outcome of central nervous system (CNS) pathologies. The focus of this review is to highlights the interactions and crosstalk of these networks in regulating pathophysiologic CNS function.

Abstract
Severe cerebral ischemia/reperfusion injury has been shown to induce high-level autophagy and neuronal death. Therefore, it is extremely important to search for a target that inhibits autophagy activation. Long non-coding RNA MEG3 participates in autophagy. However, it remains unclear whether it can be targeted to regulate cerebral ischemia/reperfusion injury. Our results revealed that in oxygen and glucose deprivation/reoxygenation-treated HT22 cells, MEG3 expression was obviously upregulated, and autophagy was increased, while knockdown of MEG3 expression greatly reduced autophagy. Furthermore, MEG3 bound miR-181c-5p and inhibited its expression, while miR-181c-5p bound to autophagy-related gene ATG7 and inhibited its expression. Further experiments revealed that mir-181c-5p overexpression reversed the effect of MEG3 on autophagy and ATG7 expression in HT22 cells subjected to oxygen and glucose deprivation/reoxygenation. In vivo experiments revealed that MEG3 knockdown suppressed autophagy, infarct volume and behavioral deficits in cerebral ischemia/reperfusion mice. These findings suggest that MEG3 knockdown inhibited autophagy and alleviated cerebral ischemia/reperfusion injury through the miR-181c-5p/ATG7 signaling pathway. Therefore, MEG3 can be considered as an intervention target for the treatment of cerebral ischemia/reperfusion injury. This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Zhengzhou University, China (approval No. XF20190538) on January 4, 2019.

Abstract
This research aimed to explore the biological role of long non-coding RNA (lncRNA) ZFAS1 in bupivacaine-induced neurotoxicity. The levels of lncRNA ZFAS1, miR-421, and zinc finger protein 564 (ZNF564) were detected by RT-qPCR. MTT and TUNEL assays were utilized to evaluate cell viability and apoptosis, respectively. Caspase-3 activity was measured by the caspase-3 activity assay kit. The binding ability between miR-421 and ZFAS1 or ZNF564 was confirmed by Rip and dual-luciferase reporter assays. In this study, it was found that the levels of ZFAS1 and ZNF564 were gradually upregulated and miR-421 expression was downregulated with increasing concentrations of bupivacaine. Functional assays indicated that the silencing of ZFAS1 suppressed cell viability and facilitated cell apoptosis of SH-SY5Y cells, while overexpression of ZFAS1 had the opposite effects. Moreover, it was identified that miR-421 was a target of ZFAS1, and ZFAS1 regulated the bupivacaine-induced neurotoxicity via miR-421. In addition, we confirmed that ZNF564 was a downstream target of miR-421. The upregulation of miR-421 decreased the cell viability, and increased the cell apoptosis rate and caspase-3 activity, while the upregulation of ZND564 partially abolished these effects. Finally, it was demonstrated that ZFAS1 could upregulate the expression of ZNF564 by targeting miR-421. In conclusion, our results demonstrated that ZFAS1 alleviated bupivacaine-induced neurotoxicity through the miR-421/ZNF564 axis, suggesting a new strategy for the amelioration of bupivacaine-induced neurotoxicity.

Abstract
Ischemic stroke (IS), caused by a permanent or transient local reduction in blood supply to the brain, is one of the most widespread causes of public health problems in modern society. Long non-coding RNA (LncRNA) has been reported to be related to angiogenesis following IS. In this study, we explored the effect and potential molecular mechanism of lncRNA homeobox antisense non-coding RNA (HOTAIR) in IS. Permanent middle cerebral artery occlusion (pMCAO) model and oxygen and glucose deprivation (OGD) model were established. HOTAIR was increased in vivo and in vitro models post-ischemic. HOTAIR knockdown promoted neurological function recovery, manifesting in decreased modified neurological severity score, cerebral infarcted area, apoptosis and inflammation, and improved balance ability, spatial learning and memory ability. Silencing HOTAIR also improved the viability of OGD-induced N2a cells, and attenuated apoptosis and inflammation. HOTAIR can compete with KLF6 to bind to miR-148a-3p. miR-148a-3p knockdown or KLF6 overexpression partially reversed the effect of sh-HOTAIR on OGD-induced N2a cells. HOTAIR suppressed the activation of STAT3 pathway via the miR-148a-3p/KLF6 axis. To summarize, this study demonstrated that lncRNA HOTAIR absorbed miR-148a-3p and up-regulated KLF6 expression through ceRNA mechanism, and inhibited STAT3 pathway, promoted apoptosis and inflammation, and aggravated neurological injury post-IS.

Neurocrit Care 2021; 36:106-115. [PMID: 34286462 DOI: 10.1007/s12028-021-01262-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 04/20/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Proliferation and apoptosis of vascular smooth muscle cells (VSMCs) are linked to intracranial aneurysm (IA) formation and progression. Long antisense noncoding RNA in the INK4 locus (ANRIL) has been reported to regulate VSMC functions in several cardiovascular diseases. However, little is known about how ANRIL influences VSMC proliferation and apoptosis during IA pathogenesis. METHODS The expression level of ANRIL in the plasma and arterial wall tissues of patients with IA was detected by real-time quantitative polymerase chain reaction. The functional role of ANRIL in the regulation of VSMC proliferation and apoptosis and its downstream regulatory mechanism were determined using Cell Counting Kit 8, immunofluorescence, terminal-deoxynucleotidyl transferase-mediated UTP nick end labeling, western blotting, luciferase reporter assay, and RNA immunoprecipitation assay. RESULTS ANRIL was downregulated in the plasma and arterial wall tissues of patients with IA, when compared with control groups. Overexpression of ANRIL significantly promoted VSMC proliferation and blocked cell apoptosis. Mechanistic studies demonstrated that ANRIL directly bound to microRNA-7 (miR-7) and that overexpression of miR-7 overturned the increased cell proliferation and decreased cell apoptosis, which was induced by ANRIL restoration. Besides, further study showed that ANRIL positively regulated fibroblast growth factor 2 (FGF2) expression via targeting miR-7. CONCLUSIONS These results suggested that ANRIL affects VSMC proliferation and apoptosis via regulation of the miR-7/FGF2 pathway in IA, which provided a potential novel strategy for the treatment of IA.

Abstract
Cerebral ischemia/reperfusion (I/R) injury leads to neuronal damage, which may cause disability and even mortality. Multiple studies have revealed that long non‑coding RNAs (lncRNAs) serve pivotal roles in the pathogenesis of cerebral I/R injury. Therefore, the present study aimed to investigate whether the lncRNA X inactivate‑specific transcript (XIST) protects neuronal cells from cerebral I/R injury. In the present study, reverse transcription‑quantitative PCR demonstrated that XIST expression was upregulated in the brain tissues of an I/R mouse model and in oxygen and glucose deprivation/reperfusion (OGD/R)‑treated Neuro‑2a (N2a) cells. Knockdown of XIST alleviated cerebral injury, as well as reduced N2a cell apoptosis and reactive oxygen species (ROS) production. Additionally, luciferase reporter and RNA immunoprecipitation assays identified that XIST could bind with microRNA (miR)‑27a‑3p. It was found that miR‑27a‑3p expression was downregulated in the brain tissues of an I/R mouse model and in OGD/R‑induced N2a cells. In addition, miR‑27a‑3p overexpression attenuated I/R‑induced cerebral injury, and inhibited the apoptosis and ROS production of N2a cells. miR‑27a‑3p was found to target FOXO3. Silencing of FOXO3 alleviated cerebral injury, as well as inhibited N2a cell apoptosis and ROS production. Collectively, these findings indicated that XIST aggravated cerebral I/R injury by regulating miR‑27a‑3p/FOXO3 signaling, which may provide a novel insight into the treatment of cerebral I/R injury.

Downregulation of lncRNA SNHG14 alleviates neurons injury by modulating the miR-181c-5p/BMF axis in ischemic stroke. Brain Res Bull 2021; 174:379-388. [PMID: 34224818 DOI: 10.1016/j.brainresbull.2021.06.026] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 06/08/2021] [Accepted: 06/30/2021] [Indexed: 12/12/2022]
Abstract
PURPOSE Our study aims to explore the role and mechanism of lncRNA small nucleolar RNA host gene 14 (SNHG14) in brain injury caused by ischemic stroke (IS). METHODS Middle cerebral artery occlusion (MCAO) model and oxygen-glucose deprivation (OGD)-induced primary cortical neurons were used to construct in vitro and in vivo models of IS, respectively. Relative SNHG14, miR-181c-5p and Bcl-2-modifying factor (BMF) expression levels were detected by quantitative real-time PCR. MTT assay, EdU staining and flow cytometry were used to measure cell proliferation and apoptosis. The protein levels of apoptosis marker and BMF were determined using western blot analysis. ELISA assay was performed to assess cell inflammatory response and injury. RESULTS SNHG14 was upregulated and miR-181c-5p was downregulated in MCAO model and OGD-induced primary cortical neurons. Silencing of SNHG14 markedly promoted proliferation, restrained apoptosis and inflammatory response in OGD-induced primary cortical neurons to alleviate neurons injury. In terms of mechanism, miR-181c-5p could be sponged by SNHG14, and its inhibitor reversed the inhibition effect of SNHG14 silencing on OGD-induced neurons injury. Also, BMF was a target of miR-181c-5p, and its overexpression could reverse the suppressive effect of miR-181c-5p on OGD-induced neurons injury. Our data uncovered that BMF expression was positively regulated by SNHG14 and negatively regulated by miR-181c-5p. CONCLUSION Our results indicated that SNHG14 promoted neurons injury through regulating miR-181c-5p/BMF axis, suggesting that SNHG14 might be a potential target to alleviate IS-induced brain injury.

Abstract
Central nervous system (CNS) injuries are one of the leading causes of morbidity and mortality worldwide, accompanied with high medical costs and a decreased quality of life. Brain vascular disorders are involved in the pathological processes of CNS injuries and might play key roles for their recovery and prognosis. Recently, increasing evidence has shown that long non-coding RNAs (lncRNAs), which comprise a very heterogeneous group of non-protein-coding RNAs greater than 200 nucleotides, have emerged as functional mediators in the regulation of vascular homeostasis under pathophysiological conditions. Remarkably, lncRNAs can regulate gene transcription and translation, thus interfering with gene expression and signaling pathways by different mechanisms. Hence, a deeper insight into the function and regulatory mechanisms of lncRNAs following CNS injury, especially cerebrovascular-related lncRNAs, could help in establishing potential therapeutic strategies to improve or inhibit neurological disorders. In this review, we highlight recent advancements in understanding of the role of lncRNAs and their application in mediating cerebrovascular pathologies after CNS injury.

Abstract
Vitamin D receptor (VDR) signaling has been reported to affect neurodevelopment, thus participating in the risk of autism spectrum disorder (ASD). We have measured expression amounts of VDR, CYP27B1, and two related long non-coding RNAs, namely SNHG6 and LINC00511, in the circulation of ASD patients compared with normal controls. Expression of CYP27B1 was remarkably higher in ASD cases compared with controls (posterior beta = 2.38, SE = 0.46, adjusted P value < 0.0001, 95% credible interval (CrI) for beta = [1.49, 3.27]). Level of SNHG6 was lower in ASD cases compared with controls (posterior beta = - 0.791, SE = 0.24, adjusted P value = 0.029, 95% CrI for beta = [- 1.27, - 0.33]). Expression levels of VDR and LINC00511 were similar between ASD cases and controls (P values = 0.97 and 0.46, respectively). Expressions of VDR, CYP27B1, SNHG6, and LINC00511 were not correlated with age of children. However, significant correlations were perceived between expressions of CYP27B1 and LINC00511 (r = 0.47, P < 0.0001), VDR and CYP27B1 (r = 0.42, P < 0.0001), and VDR and SNHG6 (r = 0.32, P < 0.0001). Therefore, these results imply dysregulation of a number of VDR-related genes in ASD patients.

Abstract
Ischemic stroke is a leading cause of disability and mortality worldwide due to the narrow therapeutic time window of the only two approved therapies, intravenous thrombolysis and thrombectomy. The pathophysiological processes of ischemic stroke are driven by multiple complex molecular and cellular interactions that ultimately induce brain damage and neurobehavioral impairment. Long non-coding RNAs (LncRNAs) are significantly altered in the blood and brains of ischemic stroke patients and play a critical role in the pathogenesis of stroke, which serve as potential targets for stroke interventions. In this review, we provide an overview of the roles of lncRNAs in the pathophysiology of ischemic stroke and discuss the opportunities and challenges for the clinical application of lncRNAs in the diagnosis and treatment of ischemic stroke.

Abstract
OBJECTIVES To examine the effects of small nucleolar RNA host gene 6 (SNHG6) on apoptosis during myocardial ischemic/reperfusion (I/R) injury and its potential molecular mechanisms. METHODS In vitro model of I/R was built through exposing mouse HL-1 cardiomyocytes to hypoxia/reoxygenation (H/R) treatment. Quantitative real-time polymerase chain reaction assays were performed to determine gene expression. Cell Counting Kit-8, flow cytometric and western blot assays were conducted to detect cell viability, apoptosis and protein expression. Lactate dehydrogenase (LDH) activity was examined by a commercial detection kit. Dual-luciferase gene reporter and RNA immunoprecipitation experiments were applied for determining the interaction between the molecules. KEY FINDINGS SNHG6 expression was increased in H/R-challenged cardiomyocytes. Depletion of SNHG6 protected against H/R-induced cardiomyocytes apoptosis. SNHG6 could sponge miR-135a-5p to inhibit its expression. Down-regulation of miR-135a-5p reversed the anti-apoptotic effect caused by SNHG6 knockdown in H/R-induced cardiomyocytes. Hypoxia inducible factor 1 subunit alpha inhibitor (HIF1AN) was identified as a direct target of miR-135a-5p, and knockdown of HIF1AN relieved H/R-induced cardiomyocytes apoptosis. Silencing of SNHG6 activated Shh/Gli1 signalling pathway by regulating miR-135a-5p/HIF1AN. Furthermore, inactivation of Shh/Gli signalling abolished the anti-apoptotic effects of SNHG6 knockdown in H/R-induced cardiomyocytes. CONCLUSIONS SNHG6 serves as a sponge for miR-135a-5p to promote HIF1AN expression and inactivate Shh/Gli1 signalling, eventually aggravating H/R-induced apoptosis in cardiomyocytes.

Abstract
JZL184 is a selective inhibitor of monoacylglycerol lipase (MAGL) that has neuroprotective effect. However, the role of JZL184 in cerebral ischemia/reperfusion (I/R) injury and the exact mechanism have not been fully understood. This study was designed to elucidate the role of JZL184 in cerebral I/R injury induced by oxygen-glucose deprivation/reoxygenation (OGD/R) in hippocampal neurons. Hippocampal neurons were pretreated with various concentrations of JZL184 for 2 h, followed by OGD for 3 h and reoxygen for 24 h. Our results showed that JZL184 improved cell viability in hippocampal neurons in response to OGD/R. JZL184 treatment significantly inhibited the production of reactive oxygen species (ROS) and malondialdehyde (MDA), as well as increased superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in OGD/R-induced hippocampal neurons. The increased TNF-α, IL-1β, and IL-6 productions in OGD/R-induced hippocampal neurons were decreased after treatment with JZL184. Moreover, the OGD/R-caused intense TUNEL staining in hippocampal neurons was attenuated by JZL184. JZL184 treatment prevented OGD/R-caused increases in bax and cleaved caspase-3 expression and a decrease in bcl-2 expression. Furthermore, JZL184 treatment significantly promoted the activation of Nrf2/ARE signaling pathway in OGD/R-induced hippocampal neurons. Additionally, silencing of Nrf2 reversed the protective effect of JZL184 on hippocampal neurons under OGD/R condition. Taken together, these findings suggested that JZL184 exerted protective effect against OGD/R-induced injury in hippocampal neurons via activating Nrf2/ARE signaling pathway, which provided in vitro experimental support for the therapeutic benefit of JZL184 in cerebral ischemia.

BIOMED RESEARCH INTERNATIONAL 2020; 2020:1817094. [PMID: 33224973 PMCID: PMC7666708 DOI: 10.1155/2020/1817094] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 09/23/2020] [Accepted: 10/03/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND This study was aimed at mining crucial long noncoding RNAs (lncRNAs), microRNAs (miRNAs), and messenger RNAs (mRNAs) for the development of polycystic ovary syndrome (PCOS) based on the coexpression and the competitive endogenous RNA (ceRNA) theories and investigating the underlying therapeutic drugs that may function by reversing the expression of lncRNAs, miRNAs, and mRNAs. METHODS RNA (GSE106724, GSE114419, GSE137684, and GSE138518) or miRNA (GSE84376 and GSE138572) expression profile datasets of PCOS patients were downloaded from the Gene Expression Omnibus database. The weighted gene coexpression network analysis (WGCNA) using four RNA datasets was conducted to construct the lncRNA-mRNA coexpression networks, while the common differentially expressed miRNAs in two miRNA datasets and module RNAs were used to establish the ceRNA network. A protein-protein interaction (PPI) network was created to explore the potential interactions between genes. Gene Ontology and KEGG pathway enrichment analyses were performed to explore the functions of genes in networks. Connectivity Map (CMap) and Comparative Toxicogenomics Database (CTD) analyses were performed to identify potential therapeutic agents for PCOS. RESULTS Three modules (black, magenta, and yellow) were identified to be PCOS-related after WGCNA analysis, in which KLF3-AS1-PLCG2, MAPKAPK5-AS1-MAP3K14, and WWC2-AS2-TXNIP were important coexpression relationship pairs. WWC2-AS2-hsa-miR-382-PLCG2 was a crucial ceRNA loop in the ceRNA network. The PPI network showed that MAP3K14 and TXNIP could interact with hub genes PLK1 (degree = 21) and TLR1 (degree = 18), respectively. These genes were enriched into mitosis (PLK1), immune response (PLCG2 and TLR1), and cell cycle (TXNIP and PLK1) biological processes. Ten small molecule drugs (especially quercetin) were considered to be therapeutical for PCOS. CONCLUSION Our study may provide a novel insight into the mechanisms and therapy for PCOS.

Onco Targets Ther 2020; 13:11411-11420. [PMID: 33192074 PMCID: PMC7656962 DOI: 10.2147/ott.s275135] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 10/16/2020] [Indexed: 12/16/2022] Open
Abstract
Background The long non-coding RNA (lncRNA) SNHG6 was significantly upregulated in esophageal squamous-cell carcinoma (ESCC), and it promoted ESCC cell proliferation, invasion, and migration. However, the effects of SNHG6 on cell apoptosis and the corresponding underlying mechanisms have not yet reported. Methods Apoptosis was detected by flow cytometric analysis. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting were used for mRNA and protein quantification, respectively. A luciferase reporter assay was performed to verify downstream target genes for SNHG6 and miR-101-3p. Results Dysregulation of SNHG6 inhibited apoptosis in ESCC cells and regulated the expression of apoptosis-related proteins such as Bcl-2, Mcl-1, Bax and Caspase-3. Functionally, miR-101-3p could compete binding with 3′-untranslated region of SNHG6 and downregulation of miR-101-3p reversed its effect on cell apoptosis in SNHG6 knockdown cells. EZH2 was confirmed as a downstream target gene of miR-101-3p, silencing EZH2 expression had the same effect on apoptosis and protein expression as knocking down SNHG6. Overexpression of EZH2 reversed the effects of miR-101-3p overexpression on cell apoptosis in ESCC cells. Conclusion In this study, we found that upregulation of the lncRNA SNHG6 inhibited apoptosis via miR-101-3p/EZH2 axis in ESCC. These findings may contribute to the diagnosis and treatment of ESCC.

LncRNA FOXD3-AS1 knockdown protects against cerebral ischemia/reperfusion injury via miR-765/BCL2L13 axis. Biomed Pharmacother 2020; 132:110778. [PMID: 33068927 DOI: 10.1016/j.biopha.2020.110778] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 09/11/2020] [Accepted: 09/17/2020] [Indexed: 12/15/2022] Open
Abstract
AIMS Long non-coding RNAs (lncRNAs) FOXD3-AS1 was reported to be increased in cardiomyocyte ischemic injury. However, its role and underlying molecular mechanism in ischemic stroke remain unknown. This study was to investigate the role of FOXD3-AS1 in cerebral ischemia/reperfusion injury. METHODS The expression of FOXD3-AS1 and miR-765 were measured with qRT-PCR. The shared putative miR-765 binding sites both in BCL2L13 and FOXD3-AS1 were identified with bioinformatics, luciferase reporter assay and RNA immunoprecipitation. Apoptosis and its related proteins were detected by TUNEL assay, Hoechst 33,258 staining, flow cytometry and western blot. Infarct volume and the neurological status were evaluated with TTC staining and neurologic deficit score, respectively. RESULTS The up-regulation of FOXD3-AS1 and down-regulation of miR-765 were found in both mouse brains after cerebral ischemia/reperfusion (I/R) and neuroblastoma cells of neuro-2A (N2a) after oxygen-glucose deprivation/reoxygenation (OGD/R). Moreover, the overexpression of miR-765 reduced N2a cell apoptosis caused by OGD/R. MiR-765 could target BCL2L13 directly. In addition, we found that FOXD3-AS1 bound to miR-765 directly, acting as a ceRNA to modulate the expression of BCL2L13. Overexpression of FOXD3-AS1 antagonized the inhibitory impact of miR-765 on the expression of BCL2L13 and the apoptosis of N2a cells treated with OGD/R, while FOXD3-AS1 knockdown promoted the inhibitory impact of miR-765 on the expression of BCL2L13 and the apoptosis of N2a cells treated with OGD/R. Furthermore, we found that neurological deficits and brain injury induced by I/R in vivo were attenuated by FOXD3-AS1 knockdown. CONCLUSIONS We verified a critical signaling pathway of FOXD3-AS1/miR-765/BCL2L13 in regulating cerebral ischemia/reperfusion injury.

Abstract
Stroke has become the most disabling and the second most fatal disease in the world. It has been a top priority to reveal the pathophysiology of stroke at cellular and molecular levels. A large number of long non-coding RNAs (lncRNAs) are identified to be abnormally expressed after stroke. Here, we summarize 35 lncRNAs associated with stroke, and clarify their functions on the prognosis through signal transduction and predictive values as biomarkers. Changes in the expression of these lncRNAs mediate a wide range of pathological processes in stroke, including apoptosis, inflammation, angiogenesis, and autophagy. Based on the exploration of the functions and mechanisms of lncRNAs in stroke, more timely, accurate predictions and more effective, safer treatments for stroke could be developed.

Long non-coding RNA small nucleolar RNA host gene 6 aggravates pancreatic cancer through upregulation of far upstream element binding protein 1 by sponging microRNA-26a-5p. Chin Med J (Engl) 2020; 133:1211-1220. [PMID: 32433053 PMCID: PMC7249703 DOI: 10.1097/cm9.0000000000000758] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Pancreatic cancer (PC) is a highly deadly malignancy with few effective therapies. We aimed to unmask the role that long non-coding RNA small nucleolar RNA host gene 6 (SNHG6) plays in PC cells by targeting far upstream element binding protein 1 (FUBP1) via microRNA-26a-5p (miR-26a-5p). METHODS SNHG6 expression was predicted by bioinformatics, followed by verification via reverse transcription quantitative polymerase chain reaction. Then, the interactions among SNHG6, miR-26a-5p, and FUBP1 were detected through online software analysis, dual luciferase reporter assay and RNA pull-down. After that, cells were treated with different small interfering RNAs and/or mimic to determine the interactions among SNHG6, miR-26a-5p, and FUBP1 and their roles in PC cells. Finally, the role of SNHG6 in tumor growth in vivo was evaluated by measuring the growth and weight of transplanted tumors in nude mice. A t-test, one-way and two-way analysis of variance were used for data analysis. RESULTS Compared with that in normal tissues, SNHG6 was highly expressed in PC tissues (1.00 ± 0.05 vs. 1.56 ± 0.06, t = 16.03, P < 0.001). Compared with that in human pancreatic duct epithelial cells (HPDE6-C7), SNHG6 showed the highest expression in PANC-1 cells (1.00 ± 0.06 vs. 3.87 ± 0.13, t = 34.72, P < 0.001) and the lowest expression in human pancreatic cancer cells (MIAPaCa-2) (1.00 ± 0.06 vs. 1.41 ± 0.07, t = 7.70, P = 0.0015). Compared with the levels in the si-negative control group, SNHG6 (0.97 ± 0.05 vs. 0.21 ± 0.06, t = 16.85, P < 0.001), N-cadherin (0.74 ± 0.05 vs. 0.41 ± 0.04, t = 8.93, P < 0.001), Vimentin (0.55 ± 0.04 vs. 0.25 ± 0.03, t = 10.39, P < 0.001), and β-catenin (0.62 ± 0.05 vs. 0.32 ± 0.03, t = 8.91, P < 0.001) were decreased, while E-cadherin (0.65 ± 0.06 vs. 1.36 ± 0.07, t = 13.34, P < 0.001) was increased after SNHG6 knockdown or miR-26a-5p overexpression, accompanied by inhibited cell proliferation, migration, and invasion. SNHG6 overexpression exerted the opposite effects. SNHG6 upregulated FUBP1 expression by sponging miR-26a-5p. Silencing SNHG6 blocked the growth of PC in vivo. CONCLUSION Silencing SNHG6 might ameliorate PC through inhibition of FUBP1 by sponging miR-26a-5p, thus providing further supporting evidence for its use in PC treatment.

Abstract
OBJECTIVES Increasing evidence confirmed that miRNA plays a critical role in the occurrence and development of ischemic stroke. Here, the aim of this study was to examine the function and mechanisms of miR-195 in vascular endothelial cell apoptosis induced by oxygen-glucose deprivation (OGD). METHODS This study intended to use OGD to simulate ischemia in vitro. The mRNA expression of miR-195, IKKα and NF-κB in human umbilical vein endothelial cells (HUVECs) were detected by RT-qPCR. The proliferation and apoptosis ability of HUVECs were evaluated using MTT assay, colony formation assay and flow cytometry, respectively. Western blot was applied to examine related protein expression. The interaction between miR-195 and IKKα was verified by dual-luciferase reporter gene assay. RESULTS OGD significantly inhibited cell viability and induced cell apoptosis in HUVECs. Meanwhile, OGD treatment notably decreased the expression of miR-195, as well as enhanced NF-κB expression. Moreover, miR-195 directly interacted with IKKα and suppressed its expression. Mechanically, overexpression of miR-195 exhibited pro-proliferation and anti-apoptotic effect on HUVECs treated with OGD through targeting IKKα-mediated NF-κB pathway. At the molecular level, through suppressing IKKα/NF-κB pathway, miR-195 inhibited the expression of pro-apoptotic protein Bax and active caspase-3, but increased the expression of anti-apoptotic Bcl-2 in HUVECs. CONCLUSIONS Our finding uncovers the protective effect of miR-195 on the biological behavior of HUVECs via suppression of the NF-κB pathway induced by IKKα, which may provide a new potential strategy for ischemic stroke clinical treatment.

Abstract
Melanoma is a common skin cancer and it can lead to high mortality probably by early invasion and metastasis. LncRNA MIAT is involved in tumor proliferation, invasion and epithelial-to-mesenchymal transition (EMT). However, the roles of MIAT in melanoma still require further investigation. Thus, the aim of the study is to investigate the roles of MIAT in melanoma, especially the effects of MIAT on EMT of melanoma cancer cells. The results showed that the expression of MIAT was significantly upregulated in melanoma tissue and cells compared with the normal skin and normal melanocytes; moreover, miR-150 was confirmed as a target of MIAT. Furthermore, knockdown of MIAT inhibited cell proliferation and invasion in melanoma cancer cells and transfection of miR-150 inhibitors partial abrogated the anti-tumor effects of MIAT siRNA. In addition, MIAT siRNA also inhibited the EMT of melanoma cells, while miR-150 inhibitors can reverse the effects of MIAT siRNA. Finally, knockdown of MIAT also inhibited the carcinogenic effects of melanoma in vivo by targeting miR-150. In conclusion, we reported that MIAT promotes the proliferation, invasion and EMT of melanoma cells via targeting miR-150, which suggested that MIAT might be a therapeutic target for the treatment of melanoma.

Abstract
It was well established that long non-coding RNAs (LncRNAs) could serve as oncogene or tumor suppressor in terms of the tumor type. FTX, as a member of lncRNA family, has been reported to be associated with several tumor progressions, such as hepatocellular carcinoma (HCC), renal cell carcinoma (RCC) and colorectal cancer. However, the regulatory role of FTX in osteosarcoma (OS) still lacks research analysis. This paper aims to explore how FTX exerts its regulatory role on OS by modulating TXNRD1/miR-320a, so as to provide a novel lncRNA theoretical framework for the diagnosis and treatment of OS. QRT-PCR revealed that FTX and TXNRD1 were abnormally upregulated in OS, whereas miR-320a expression was significantly decreased. Luciferase reporter analysis showed that both FTX and TXNRD1 could combine with miR-320a. A series of functional experiments indicated that knockdown of FTX could suppress OS cell proliferation and migration, while facilitating apoptosis ability simultaneously. However, TXNRD1 overexpression or miR-320a inhibition could rescue the oncogenic function of FTX. Taken all the experiment results together, this paper indicated that FTX impacted osteosarcoma cell proliferation and migration by modulating TXNRD1/miR-320a.

Abstract
Despite advanced clinical treatments, mortality in patients with metastatic colorectal cancer (CRC) remains high. Three critical determinants in CRC progression include the epithelial proliferation checkpoints, epithelial-to-mesenchymal transition (EMT) and inflammatory cytokines in the tumour microenvironment. Genes involved in these three processes are regulated at the transcriptional and post-transcriptional level. Recent studies revealed previously unappreciated roles of non-coding ribonucleic acids (ncRNAs) in modulating the proliferation checkpoints, EMT, and inflammatory gene expression in CRC. In this review, we will discuss the mechanisms underlying the roles of ncRNAs in CRC as well as examine future perspectives in this field. Better understanding of ncRNA biology will provide novel targets for future therapeutic development.

Abstract
Excessive oxidative stress causes neuronal cell injury. Long non-coding RNA (LncRNA) EPIC1 (Lnc-EPIC1) is a MYC-interacting LncRNA. Its expression and potential functions in hydrogen peroxide (H2O2)-stimulated neuronal cells are studied. In SH-SY5Y neuronal cells and primary human neuron cultures, H2O2 downregulated Lnc-EPIC1 and key MYC targets (Cyclin A1, CDC20 and CDC45). Ectopic overexpression of Lnc-EPIC1 increased expression of MYC targets and significantly attenuated H2O2-induced neuronal cell death and apoptosis. Contrarily, Lnc-EPIC1 siRNA potentiated neuronal cell death by H2O2. MYC knockout by CRISPR/Cas9 method also facilitated H2O2-induced SH-SY5Y cell death. Significantly, MYC knockout abolished Lnc-EPIC1-induced actions in H2O2-stimulated neuronal cells. Together, these results suggest that Lnc-EPIC1 downregulation mediates H2O2-induced neuronal cell death.

Abstract
Spinal cord injury (SCI) is a highly debilitating disease and is increasingly being recognized as an important global health priority. However, the mechanisms underlying SCI have not yet been fully elucidated, and effective therapies for SCI are lacking. Long noncoding RNAs (lncRNAs), which form a major class of noncoding RNAs, have emerged as novel targets for regulating several physiological functions and mediating numerous neurological diseases. Notably, gene expression profile analyses have demonstrated aberrant changes in lncRNA expression in rats or mice after traumatic or nontraumatic SCI. LncRNAs have been shown to be associated with multiple pathophysiological processes following SCI including inflammation, neural apoptosis, and oxidative stress. They also play a crucial role in the complications associated with SCI, such as neuropathic pain. At the same time, some lncRNAs have been found to be therapeutic targets for neural stem cell transplantation and hydrogen sulfide treatment aimed at alleviating SCI. Therefore, lncRNAs could be promising biomarkers for the diagnosis, treatment, and prognosis of SCI. However, further researches are required to clarify the therapeutic effects of lncRNAs on SCI and the mechanisms underlying these effects. In this study, we reviewed the current progress of the studies on the involvement of lncRNAs in SCI, with the aim of drawing attention towards their roles in this debilitating condition.

Abstract
Long non-coding RNAs (lncRNAs) play important roles in the pathogenesis of brain and neurodegenerative disorders. As far as we know, the functions and potential mechanisms of small nucleolar RNA host gene 6 (SNHG6) in ischaemic stroke have not been explored. This study aimed to examine the functional role of SNHG6 in the ischaemic stroke. Middle cerebral artery occlusion (MCAO) in mice and the oxygen glucose deprivation (OGD)-induced injury in neuronal cells were applied to mimic ischaemic stroke. TTC staining, quantitative real-time PCR, cell apoptosis assay, caspase-3 activity assay, Western blot, RNA immunoprecipitation and luciferase reporter assay were performed to evaluate the function and possible mechanisms of SNHG6 in the pathogenesis of ischaemic stroke. The results show that SNHG6 expression was significantly increased both OGD-induced neuronal cells and MCAO model mice. In vitro results showed that inhibition of SNHG6 increased cell viability, inhibited cell apoptosis and caspase-3 activity in OGD-induced neuronal cells. Consistently, knockdown of SNHG6 reduced brain infarct size and improved neurological scores in the MCAO mice. Mechanistic study further revealed that SNHG6 functioned as a competing endogenous RNA (ceRNA) for miR-181c-5p, which in turn repressed its downstream target of Bcl-2 interacting mediator of cell death (BIM) and inhibiting cell apoptosis. This study revealed a novel function of SNHG6 in the modulating neuronal apoptosis in the ischaemic stroke model, and the role of SNHG6 in the regulating of neuronal apoptosis was at least partly via targeting miR-181c-5p/BIM signalling pathway.
