Abstract
Hepatocellular carcinoma (HCC) is the fifth most frequently diagnosed cancer and ranks third in cancer-related fatalities. The recognized involvement of long noncoding RNAs (lncRNAs) in several cancer types, including HCC, inspired this study to explore a novel lncRNA's functional importance in the progression of HCC. To achieve this, lncRNA microarray analysis was conducted on three distinct sets of HCC tissues, revealing LINC00707 as the most significantly upregulated lncRNA. Further research into its biological functions has revealed that LINC00707 acts as an oncogene, driving HCC progression by enhancing the proliferation, migration and invasion of HCC cells. Mechanistic insights were provided, demonstrating that LINC00707 interacts with YTH N6-methyladenosine RNA-binding protein 2 (YTHDF2), thus facilitating the ubiquitination-dependent degradation of the YTHDF2 protein. Furthermore, LINC00707 was found to influence the cytotoxicity of NK-92MI cells against HCC cells through its interactions with YTHDF2. These findings significantly contribute to a deeper understanding of the role played by LINC00707 in the progression of HCC.

Abstract
The role of microglia in traumatic brain injury (TBI) has gained considerable attention. The present study aims to elucidate the potential mechanisms of Long intergenic non-protein coding RNA 707 (LINC00707) in TBI-induced microglia activation and inflammatory factor release. An in vivo model of rat TBI and in vitro microglia model was established using Controlled cortex injury (CCI) and lipopolysaccharide (LPS) stimulation. RT-qPCR to detect LINC00707 levels in rat cerebral cortex or cells. Modified Neurological Impairment Score (mNSS) and Morris Water Maze test was conducted to assess the neurological deficits and cognitive impairment. ELISA analysis of pro-inflammatory factors levels. CCK-8 and flow cytometry for cell viability and apoptosis levels. Dual-luciferase report and RIP assay to validate the targeting relationship between LINC00707 and miR-30a-5p. LINC00707 was elevated in the TBI rat cerebral cortex and LPS-induced microglia, while miR-30a-5p was noticeably decreased (P < 0.05). Increased mNSS, cognitive dysfunction, and brain edema in TBI rats were all prominently reversed by silencing of LINC00707, but this reversal was partially abrogated by decreasing miR-30a-5p (P < 0.05). Inhibition of LINC00707 suppressed the overproduction of inflammatory factors in TBI rats (P < 0.05). LPS decreased microglial cell viability, increased apoptosis, and promoted inflammatory overproduction than control, but the silencing of LINC00707 reversed its effect. Suppression of miR-30a-5p attenuated this reversal (P < 0.05). miR-30a-5p was the target miRNA of LINC00707. All in all, the results suggested that inhibiting LINC00707/miR-30a-5p axis could alleviate the progression of TBI by suppressing the inflammation and apoptosis of microglia cells.

Abstract
BACKGROUND Sepsis poses a serious threat to human life and health, with limited options for current clinical treatments. Acupuncture plays an active role in treating sepsis. However, previous studies have focused on the neuromodulatory effect of acupuncture, neglecting its network modulatory effect. Exosomes, as a new way of intercellular communication, may play an important role in transmitting acupuncture information. This paper explores the possibility of electroacupuncture-driven endogenous circulating serum exosomes and their carried miRNAs as a potential treatment for sepsis. METHODS The sepsis mouse model was established by intraperitoneal injection of lipopolysaccharide (LPS) (12 mg/kg, 24 mg/kg), and EA (continuous wave, 10 Hz, intensity 5) or intraperitoneal injection of Acupuncture Exosomes (Acu-exo) were performed before the model establishment. The therapeutic effect was evaluated by survival rate, ELISA, H&E staining and lung wet/dry weight ration (W/D). In vivo imaging of small animals was used to observe the accumulation of Acu-exo in various organs of sepsis mice. LPS was used to induce macrophages in cell experiments, and the effect of Acu-exo on macrophage inflammatory cytokines was observed. In addition, The miRNA sequencing method was further used to detect the serum exosomes of normal and EA-treated mice, and combined with network biology analysis methods to screen possible key targets. RESULTS EA and Acu-exo reduced the W/D and lung tissue damage in sepsis mice, down-regulated the expression of serum inflammatory cytokines TNF-α and IL-6, and increased the survival rate of sepsis mice. In vivo imaging of small animals found that Acu-exo were accumulated in the lungs of sepsis mice. Cell experiments proved that Acu-exo down-regulated the expression of inflammatory cytokines TNF-α, IL-6 and IL-1β to alleviate the inflammatory response induced by LPS in macrophages. MiRNA sequencing revealed 53 differentially expressed miRNAs, and network biology analysis revealed the key targets of Acu-exo in sepsis treatment. CONCLUSION Electroacupuncture-driven endogenous circulating serum exosomes and their carried miRNAs may be a potential treatment for sepsis.

Abstract
LINC00707 is a lncRNA that can regulate a variety of diseases. This study mainly investigated that the expression of LINC00707 in rheumatic heart disease (RHD) and LINC00707 regulates S1PR1 by targeting miR-145-5p to inhibit myocardial fibrosis and immune disorder in RHD. A rat model of RHD induced by inactivated group A β-hemolytic streptococcus (GSA) was established. Sixty female Lewis rats (8 weeks of age) were randomly divided into six groups, including control (Con), RHD, RHD+NC, RHD+LINC00707, RHD+miR-145-5p and RHD+LINC00707+miR-145-5p. The mRNA expression was detected by Quantitative Real-time polymerase chain reaction (qRT-PCR). Protein expression of S1PR1 was detected by western blot. The levels of myocardial damage markers (CK-MB, cTnl) and inflammatory immune markers (IL-6, IL-17 and IL-21) were measured by enzyme linked immunosorbent assay (ELISA). The Collagen III/I(COLIII/I) ratio, mRNA expression of COLIIIα1 and FSP1 of rat heart valve tissue in the RHD group was observably higher by comparison with the CON group. The expression of LINC00707 was observably lower in the RHD group. LINC00707 inhibited myocardial fibrosis and immune disorder in RHD. MiR-145-5p was the target gene of LINC00707 via Targetscan prediction. Luciferase reporter experiment confirmed that miR-145-5p was directly regulated by LINC00707. The expression of miR-145-5p in the RHD group was observably higher by comparison with the CON group and LINC00707 observably decreased the expression of miR-145-5p. miR-145-5p mimic reversed the inhibiting effect of LINC00707 on myocardial fibrosis and immune disorder. Furthermore, S1PR1 was confirmed to be downstream gene of miR-145-5p and low expressed in the RHD model. LINC00707 could inhibit myocardial fibrosis and immune disorder in RHD by regulating miR-145-5p/S1PR1.

Abstract
Spinal cord injury (SCI) can result in a partial or complete loss of motor and sensory function below the injured segment, which has a significant impact on patients' quality of life and places a significant social burden on them. Long non-coding RNA (LncRNA) is a 200-1000 bp non-coding RNA that has been shown to have a key regulatory role in the progression of a variety of neurological illnesses. Many studies have demonstrated that differentially expressed LncRNAs following spinal cord injury can participate in inflammatory damage, apoptosis, and nerve healing by functioning as competitive endogenous RNA (ceRNA); at the same time, it has a significant regulatory effect on sequelae such neuropathic pain. As a result, we believe that LncRNAs could be useful as a molecular regulatory target in the diagnosis, treatment, and prognosis of spinal cord injury.

Abstract
Infantile pneumonia (IP) is an acute lower respiratory infection that imposes a heavy burden on children's health. Increasing evidence has demonstrated that long non-coding RNA (lncRNA) LINC00707 participates in the regulation of the pneumonia process. Cell proliferative ability and apoptosis were measured using Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU), and flow cytometry assays. Bcl-2 related X protein (Bax), NF-kB activating protein (NKAP), p-P65, P65, p-IκBα, and IκBα protein levels were detected using western blot assay. The binding between miR-382-5p and LINC00707 or NKAP was predicted by starBase v2.0 and then verified by a dual-luciferase reporter and RNA Immunoprecipitation (RIP) assays. LINC00707 and NKAP levels were increased, and miR-382-5p was decreased in LPS-stimulated WI-38 cells. Furthermore, the silencing of LINC00707 could abrogate LPS-engendered WI-38 cell proliferation, apoptosis, and oxidative stress. LINC00707 deficiency could relieve LPS-triggered WI-38 cell damage by regulating the miR-382-5p/NKAP axis, providing a new therapeutic strategy for IP treatment.

Abstract
BACKGROUND Osteoarthritis (OA) is a severe disabling condition that causes major health problems. The roles of lncRNAs in regulating OA progression have been increasingly researched. Based on previously published microarray analysis, LINC00707 is upregulated in OA. This research was done to uncover the function of LINC00707 in IL-1β-induced chondrocyte injury and its possible mechanisms. METHODS LINC00707, miR-330-5p, and FSHR expression in OA cartilage tissues were assessed by RT-qPCR. Primary chondrocytes were isolated from OA tissues and treated with IL-1β to establish an in vitro OA model. Under the indicated treatment, chondrocyte apoptosis, senescence, ECM degradation, and inflammation were determined using flow cytometry, TUNEL, SA-β-Gal staining, and ELISA experiments, respectively. Interactions between gene were evaluated using Ago2 RIP and luciferase reporter assays. RESULTS LINC00707 and FSHR were elevated, and miR-330-5p was reduced in cartilage tissues of OA patients and in IL-1β-treated primary chondrocytes. Silencing LINC00707 hampered chondrocytes apoptosis, senescence, ECM degradation, and inflammation. LINC00707 acted as a ceRNA to regulate FSHR through controlling miR-330-5p availability. Additionally, both miR-330-5p depletion and FSHR overexpression diminished the effects of silencing LINC00707 in OA progression. CONCLUSION Silencing LINC00707 mitigates chondrocyte injury in osteoarthritis via sponging miR-330-5p and inhibiting FSHR.

Abstract
Long noncoding RNAs (lncRNAs) are a major type of noncoding RNA greater than 200 nucleotides in length involved in important regulatory processes. Abnormal expression of certain lncRNAs contributes to the pathogenesis of multiple diseases, including cancers. The lncRNA LINC00707 is located on chromosome 10p14 and is abnormally expressed in numerous disease types, and particularly in several types of cancer. High LINC00707 levels mediate a series of biological functions, including cell proliferation, apoptosis, metastasis, invasion, cell cycle arrest, inflammation, and even osteogenic differentiation. In this review, we discuss the main functions and underlying mechanisms of LINC00707 in different diseases and describe promising applications of LINC00707 in clinical settings.

Abstract
Acute respiratory distress syndrome (ARDS) is a severe pulmonary disease, which can be modulated by certain long non-coding (lnc)RNAs. The present study aimed to investigate the regulatory mechanism of lncRNA HOTAIR in ARDS and the inflammatory response induced by lipopolysaccharide (LPS). The mRNA expression levels of HOTAIR, microRNA (miR)-30a-5p and PDE7A were determined using reverse transcription-quantitative PCR, while a MTT assay was used to assess the viability of the MLE-12 cells and ELISA was used to determine the concentration of different inflammatory factors [tumor necrosis factor (TNF)-α, IL-1β and IL-6]. The interactions between miR-30a-5p and HOTAIR/PDE7A were predicted using TargetScan and StarBase databases and verified using a dual-luciferase reporter assay. The protein expression levels of PDE7A were determined using western blot analysis. Mouse models of LPS-induced ARDS were established to investigate the suppressive effect of HOTAIR knockdown on ARDS in vivo. lncRNA HOTAIR was increased in LPS-treated MLE-12 cells and in a ARDS mouse model. HOTAIR knockdown decreased the concentration of TNF-α, IL-1β and IL-6, and increased cell viability in vitro. miR-30a-5p upregulation decreased TNF-α, IL-1β and IL-6 concentrations, and increased cell viability in vitro. HOTAIR targeted miR-30a-5p and miR-30a-5p targeted PDE7A. miR-30a-5p downregulation and PDE7A upregulation reversed the suppressive effect of HOTAIR knockdown on the concentrations of TNF-α, IL-1β and IL-6, and the positive effect of HOTAIR knockdown on cell viability in vitro. HOTAIR knockdown also attenuated ARDS and the inflammatory response induced by LPS in vivo. The suppression of HOTAIR alleviated ARDS and the inflammatory response induced by LPS by modulating the miR-30a-5p/PDE7A axis. These results provide a potential therapeutic strategy for ARDS.

Abstract
Central nervous system (CNS) diseases are responsible for a large proportion of morbidity and mortality worldwide. CNS diseases caused by intrinsic and extrinsic stimuli stimulate the resident immune cells including microglia and astrocyte, resulting in neuroinflammation that exacerbates the progression of diseases. Recent evidence reveals the aberrant expression patterns of long non-coding RNAs (lncRNAs) in the damaged tissues following CNS diseases. It was also proposed that lncRNAs possessed immune-modulatory activities by directly or indirectly affecting various effector proteins including transcriptional factor, acetylase, protein kinase, phosphatase, etc. In addition, lncRNAs can form a sophisticated network by interacting with other molecules to regulate the expression or activation of downstream immune response pathways. However, the major roles of lncRNAs in CNS pathophysiologies are still elusive, especially in neuroinflammation. Herein, we tend to review some potential roles of lncRNAs in modulating neuroinflammation based on current evidence in various CNS diseases, in order to provide novel explanations for the initiation and progression of CNS diseases and help to establish therapeutic strategies targeting neuroinflammation.

Abstract
Spinal cord injury (SCI) is a severe CNS injury that results in abnormalities in, or loss of, motor, sensory and autonomic nervous function. miRNAs belong to a new class of noncoding RNA that regulates the production of proteins and biological function of cells by silencing translation or interfering with the expression of target mRNAs. Following SCI, miRNAs related to oxidative stress, inflammation, autophagy, apoptosis and many other secondary injuries are differentially expressed, and these miRNAs play an important role in the progression of secondary injuries after SCI. The purpose of this review is to elucidate the differential expression and functional roles of miRNAs after SCI, thus providing references for further research on miRNAs in SCI.

Abstract
Spinal cord injury (SCI) is a traumatic central nervous system disorder that leads to permanent functional loss, and unavailable treatment of this disease results in poor quality of life. However, the specific role of long non-coding RNA small nucleolar RNA host gene 14 (lncRNA SNHG14) in SCI has not been fully studied. The aim of the current study was to investigate the role of SNHG14 and its regulatory mechanism in lipopolysaccharide (LPS)-induced PC-12 cells. LPS was used to stimulate PC-12 cells to simulate inflammatory injury following SCI in vitro. Cell viability and apoptosis were respectively assessed by Cell Counting Kit-8 assay and TUNEL assay. Western blotting was performed to detect the expressions of apoptosis-related proteins. The mRNA levels of SNHG14 and microRNA (miR)-181b-5p were detected by reverse transcription-quantitative PCR. The target of SNGH14 was predicted by bioinformatics analysis and subsequently validated by a luciferase reporter assay. ELISA was then used to detect the levels of inflammatory factors. The results indicated that LPS induced inflammation, decreased cell viability and increased the apoptosis of PC-12 cells. Interference of SNHG14 alleviated this type of injury of PC-12 cells. Bioinformatics prediction and luciferase reporter assay demonstrated that miR-181b-5p could directly bind to SNHG14. Moreover, mechanistic investigations revealed that the miR-181b-5p inhibitor could reverse the inhibitory effects of SNHG14 silencing on cell viability, inflammation and apoptosis of PC-12 cells. To conclude, the present results showed that SNHG14 knockdown alleviated PC-12 cell inflammation and apoptosis induced by LPS via regulating miR-181b-5p, which might provide a novel insight into the treatment of SCI.

Abstract
Pneumonia is a common respiratory disease worldwide. Long noncoding RNAs have been implicated in the pathogenesis of pneumonia. However, the effect and mechanism of long intergenic nonprotein-coding RNA (LINC00707) on pneumonia pathogenesis were still unclear. Lipopolysaccharide (LPS) reduced cell viability and promoted apoptosis and inflammation in MRC-5 cells. LINC00707 was increased, and miR-223-5p was decreased in LPS-treated MRC-5 cells. LINC00707 knockdown relieved LPS-triggered injury in MRC-5 cells. LINC00707 directly interacted with miR-223-5p through acting as a miR-223-5p sponge. Moreover, miR-223-5p mediated the regulation of LINC00707 silencing on LPS-stimulated cytotoxicity in MRC-5 cells. p38 mitogen-activated protein kinases and nuclear factor-κB signaling pathways were modulated by the LINC00707/miR-223-5p axis in LPS-induced MRC-5 cells. Our present study indicated that LINC00707 depletion alleviated LPS-induced injury in MRC-5 cells at least partly by acting as a sponge of miR-223-5p, highlighting a new potential therapeutic avenue for pneumonia treatment.

Abstract
LncRNAs have emerged as important regulatory molecules in biological processes. They serve as regulators of gene expression pathways through interactions with proteins, RNA, and DNA. LncRNA expression is altered in several diseases of the central nervous system (CNS), such as neurodegenerative disorders, stroke, trauma, and infection. More recently, it has become clear that lncRNAs contribute to regulating both pro-inflammatory and anti-inflammatory pathways in the CNS. In this review, we discuss the molecular pathways involved in the expression of lncRNAs, their role and mechanism of action during gene regulation, cellular functions, and use of lncRNAs as therapeutic targets during neuroinflammation in CNS disorders.

LncRNA SOX2OT Knockdown Alleviates Lipopolysaccharide-Induced Damage of PC12 Cells by Regulating miR-331-3p/Neurod1 Axis. World Neurosurg 2020; 147:e293-e305. [PMID: 33340723 DOI: 10.1016/j.wneu.2020.12.049] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 12/07/2020] [Accepted: 12/08/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Long noncoding RNAs (lncRNAs) serve as crucial regulators in the pathogenesis of spinal cord injury (SCI). However, the role of lncRNA SOX2 overlapping transcript (SOX2OT) in SCI remains to be well revealed. METHODS An SCI rat model was established and assessed by the Basso-Beattie-Bresnahan (BBB) method. An SCI PC12 cell model was established through lipopolysaccharide (LPS) treatment. Quantitative real-time polymerase chain reaction assay was used for SOX2OT, miR-331-3p, and neurogenic differentiation 1 (Neurod1) mRNA levels. Cell counting kit-8 assay and flow cytometry analysis were performed for cell viability and apoptosis, respectively. Enzyme-linked immunosorbent assay was performed for the levels of inflammatory cytokines. The production of superoxide dismutase and malondialdehyde was determined with relevant kits. Dual-luciferase reporter and RNA immunoprecipitation assays were conducted for the relationships among SOX2OT, miR-331-3p, and Neurod1. Western blot assay was employed for protein levels. RESULTS SOX2OT was elevated in SCI rat and cell models. SOX2OT knockdown relieved the injury of SCI in SCI rat model. Moreover, the suppressive role in PC12 cell viability and the promotional roles in apoptosis, inflammation, and oxidative stress mediated by LPS were all restored by silencing SOX2OT. For mechanism analysis, SOX2OT was identified as a sponge of miR-331-3p to positively regulate Neurod1 expression. Inhibition of miR-331-3p reversed the effect of SOX2OT knockdown on LPS-induced PC12 damage. Overexpression of miR-331-3p protected PC12 cells from LPS-induced damage by binding to Neurod1. In addition, SOX2OT knockdown relieved PC12 cell injury by inactivation of Janus kinase-signal transducer and activator of transcription pathway. CONCLUSIONS SOX2OT promoted PC12 cell injury through modulating miR-331-3p/Neurod1 axis and activating Janus kinase-signal transducer and activator of transcription pathway.

Abstract
MicroRNAs (miRNAs) are reported to be involved in renal hypoxia/reoxygenation (H/R) damage. To investigate this further, human kidney (HK-2) cells were cultured, subjected to H/R and the function of miR-30a-5p and glutamate dehydrogenase 1 (GLUD1) was evaluated. The results showed that, miR-30-5p was downregulated and GLUD1 was upregulated in HK-2 cells exposed to H/R. The relationship between miR-30a-5p and GLUD1 was determined using dual luciferase assays. Primary HK-2 cells were cultured in H/R and transfected with negative control 1 (NC1), negative control 2 (NC2), mimic, inhibitor or GLUD1 siRNA plasmids. Reactive oxygen species (ROS) generation, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities, and the rate of apoptosis in HK-2 cells were assessed. The results showed that, miR-30a-5p mimic reduced the production of ROS in HK-2 cells treated with H/R, but increased the activity of SOD, CAT and GPx. In addition, miR-30a-5p mimic significantly decreased H/R-mediated apoptosis, decreased the expression of bax and activity of caspase-3 and enhanced the expression of bcl-2. However, miR-30a-5p inhibitor showed the opposite effect with regard to the degree of oxidative damage and apoptosis in H/R-induced HK-2 cells. Silencing GLUD1 rescued the influence of miR-30a-5p inhibitor on oxidative injury and apoptosis in HK-2 cells stimulated with H/R. These results demonstrated that under H/R conditions, miR-30a-5p can reduce oxidative stress in vitro by targeting GLUD1, which may be a novel therapeutic target for liver failure and worth further study.

Abstract
Introduction Ketamine, which is widely used in anesthesia, can induce cortical neurotoxicity in patients. This study aims to investigate the effects of long non-coding RNA LINC00641 on the ketamine-induced neural injury. Materials and Methods In this study, rat pheochromocytoma cells (PC12 cells) were used as a cell model and Sprague–Dawley postnatal day 7 rats were used for experiments in vivo. Ketamine-induced aberrant expression levels of LINC00641, miR-497-5p and brain-derived neurotrophic factor (BDNF) were examined by qRT-PCR. The effects of LINC00641 and miR-497-5p on ketamine-induced neural injury were then examined by MTT assays and TUNEL analysis. In addition, the activity of ROS and caspase-3 was measured. The regulatory relationships between LINC00641 and miR-497-5p, miR-497-5p and BDNF were detected by dual-luciferase reporter assay, respectively. Results Ketamine induced the apoptosis of PC12 cells, accompanied by down-regulation of LINC00641 and BDNF, and up-regulation of miR-497-5p. LINC00641 overexpression enhanced the resistance to the apoptosis of PC12 cells, while transfection of miR-497-5p had opposite effects. Furthermore, LINC00641 could bind to miR-497-5p and reduce its expression, but indirectly increase the BDNF expression, which was considered as a protective factor in neural injury and activated TrkB/PI3K/Akt pathway. Conclusion Collectively, LINC00641/miR-497-5p/BDNF axis was validated to be an important signaling pathway in modulating ketamine-induced neural injury.

Abstract
Long non-coding RNAs (lncRNAs) have been indicated to serve critical roles in cancer development and progression. Long intergenic non-protein coding RNA 70 (LINC00707) was recently reported to be an oncogene involved in the tumorigenesis of several types of human cancer. However, the clinical role, biological functions and molecular mechanism of LINC00707 in colorectal cancer (CRC) remain unclear. The aim of the present study was to investigate the biological effects and mechanism of LINC00707 in CRC. Reverse transcription-quantitative PCR was used to detect the expression levels of LINC00707 in 65 CRC tissue samples and CRC cell lines (HCT116, HT29 and SW480). Cell Counting Kit-8 and colony formation assays were performed to investigate the effects of LINC00707 on CRC cell proliferation. A dual-luciferase reporter assay was conducted to investigate the mechanisms of LINC00707 in CRC. The upregulation of LINC00707 expression was significantly associated with tumor size, stage and poor survival in patients with CRC. LINC00707 also acted as an independent prognostic factor for CRC. Functional analyses revealed that the knockdown of LINC00707 could inhibit CRC cell proliferation. Furthermore, bioinformatics analysis demonstrated that microRNA (miR)-485-5p could directly bind to LINC00707, which was confirmed by a dual-luciferase reporter assay. In conclusion, the upregulation of LINC00707 is associated with a shorter survival time in patients with CRC. Knockdown of LINC00707 may inhibit the proliferation of CRC cells by binding with miR-485-5p.
