Introduction: Cyclin Dependent Kinase Inhibitor 2A (CDKN2A) is involved in glioma progression, but the specific molecular mechanism of CDKN2A in glioma cell migration and invasion needs to be further explored.

Material and methods: Data related to CDKN2A expression and glioma overall survival were obtained from The Cancer Genome Atlas (TCGA) database. Then, CDKN2A expression in glioma tissues/cells or paracancer tissues/astrocytes was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) or Western blot. Afterwards, Wound healing, Transwell and tube formation assay were performed to identify the invasion, migration and angiogenesis of glioma cells, respectively. TargetScan database predicted the targeted binding between miR-484 and CDKN2A, which was verified by dual luciferase reporter gene assay. Western blot and qRT-PCR were performed to detect the expression of VEGF, E-cadherin, N-cadherin and Vimentin in glioma cells.

Results: CDKN2A was low-expressed in glioma tissue/cells as compared to paracancer tissue/astrocytes, and was strongly associated to the poor prognosis of glioma. Further studies found that down-regulation of CDKN2A could promote migration, invasion and angiogenesis of glioma cells. Besides, miR-484 was high-expressed in glioma cells compared to astrocytes. Up-regulation of miR-484 could enhance migration, invasion and angiogenesis of glioma cells. In addition, up-regulated miR-484 suppressed the expression of E-cadherin, and promoted the expression of N-cadherin, Vimentin and VEGF. However, there was negative regulation of miR-484 and CDKN2A, and CDKN2A could partially offset the effect of miR-484.

Conclusions: MiR-484 promoted cell migration, invasion and angiogenesis by inhibiting CDKN2A expression.

引言:细胞周期蛋白依赖性激酶抑制剂2A(CDKN2A)参与神经胶质瘤的进展,但其在神经胶质瘤细胞迁移和侵袭中的具体分子机制有待进一步探索。材料和方法:从癌症基因组图谱(TCGA)数据库中获得CDKN2A表达和胶质瘤总生存率的相关数据。然后,通过定量逆转录聚合酶链反应(qRT-PCR)或蛋白质印迹测定CDKN2A在神经胶质瘤组织/细胞或癌旁组织/星形胶质细胞中的表达。然后,分别进行创伤愈合、Transwell和管形成试验,以鉴定神经胶质瘤细胞的侵袭、迁移和血管生成。TargetScan数据库预测了miR-484和CDKN2A之间的靶向结合,这通过双荧光素酶报告基因分析得到了验证。Western blot和qRT-PCR检测VEGF、E-钙粘蛋白、N-钙粘蛋白和Vimentin在胶质瘤细胞中的表达。结果:与癌旁组织/星形胶质细胞相比,CDKN2A在神经胶质瘤组织/细胞中的表达较低,与神经胶质瘤的不良预后密切相关。进一步研究发现,下调CDKN2A可促进胶质瘤细胞的迁移、侵袭和血管生成。此外,与星形胶质细胞相比,miR-484在神经胶质瘤细胞中高表达。上调miR-484可以增强神经胶质瘤细胞的迁移、侵袭和血管生成。此外,上调的miR-484抑制E-钙粘蛋白的表达,并促进N-钙粘蛋白、波形蛋白和VEGF的表达。然而,miR-484和CDKN2A存在负调控,CDKN2A可以部分抵消miR-484的作用。结论:miR-484通过抑制CDKN2A的表达来促进细胞迁移、侵袭和血管生成。

Introduction: Glioma is one of primary brain tumours which has the worst clinical prognoses of patients. As an alternative chemotherapeutic drug for malignant glioma, the therapeutic effect of cisplatin (CDDP) is devastatingly affected due to resistance in patients. In this study, we investigated the effect of LINC00470/PTEN on the CDDP sensitivity of glioma cells.

Material and methods: Differentially expressed lncRNAs and the downstream regulators in glioma tissue were obtained via bioinformatics analysis. LINC00470 and PTEN mRNA expression levels were detected using qRT-PCR. IC50 values of glioma cells were examined using Cell Counting Kit-8 (CCK-8). Cell apoptosis was revealed by flow cytometry. The expression level of autophagy-related protein was detected by western blot. Intracellular autophagosome formation was detected by immunofluorescence staining, and the methylation level of PTEN promoter was detected via methylation-specific PCR (MSP).

Results: Through the above steps, we found that LINC00470 was highly expressed in glioma cells, and the survival rate of patients was reduced in the presence of high expression of LINC00470. Silenced LINC00470 promoted LC3 II expression and autophagosome formation, and facilitated cell apoptosis to inhibit resistance to CDDP. While silenced PTEN could successfully reverse the previous effects on glioma cells.

Conclusions: Based on the above, LINC00470 repressed cell autophagy by constraining PTEN, thereby enhancing CDDP resistance of glioma cells.

神经胶质瘤是临床预后最差的原发性脑肿瘤之一。顺铂(CDDP)作为恶性胶质瘤的替代化疗药物,由于患者的耐药,严重影响了其治疗效果。在本研究中,我们研究了LINC00470/PTEN对胶质瘤细胞CDDP敏感性的影响。材料与方法:通过生物信息学分析获得胶质瘤组织中差异表达的lncrna及其下游调控因子。采用qRT-PCR检测LINC00470和PTEN mRNA表达水平。使用细胞计数试剂盒-8 (CCK-8)检测胶质瘤细胞的IC50值。流式细胞术检测细胞凋亡情况。western blot检测自噬相关蛋白的表达水平。免疫荧光染色检测细胞内自噬体形成,甲基化特异性PCR (methyl- specific PCR, MSP)检测PTEN启动子甲基化水平。结果:通过以上步骤,我们发现LINC00470在胶质瘤细胞中高表达,并且在LINC00470高表达的情况下,患者的生存率降低。沉默的LINC00470可促进LC3 II的表达和自噬体的形成,促进细胞凋亡,从而抑制CDDP的耐药。而沉默的PTEN可以成功地逆转先前对胶质瘤细胞的影响。结论:综上所述,LINC00470通过抑制PTEN抑制细胞自噬,从而增强胶质瘤细胞对CDDP的抗性。

Introduction: Acute cerebral ischemic stroke (AIS) dramatically influences patients' quality of life. lncRNA NORAD (NORAD) has been studied in cerebrovascular diseases, which are potential risk factors for AIS. The specific significance of NORAD is unclear. This study aimed to assess the role of NORAD in AIS, and to provide therapeutic value for its' treatment.

Material and methods: A total of 103 AIS patients and 95 healthy individuals (control) were enrolled into this study. Expression level of NORAD in the plasma of all participants was analyzed by PCR. Diagnostic potential of NORAD in AIS was evaluated by ROC analysis, while Kaplan-Meier and Cox regression analyses were conducted to assess its' prognostic value in AIS.

Results: A significantly increased level of NORAD was observed in AIS patients compared with healthy individuals. The upregulation of NORAD could dramatically discriminate AIS patients from healthy individuals with high sensitivity (81.60%) and specificity (88.40%). NORAD was positively correlated with patients' high-sensitivity C-reactive protein (hs CRP, r = 0.796), matrix metalloproteinase-9 (MMP9, r = 0.757), and NIHSS scores ( r = 0.840), and negatively related to pc-ASPECTS scores ( r = -0.607). Moreover, NORAD upregulation was associated with patients' unfavorable prognosis and served as an independent prognostic biomarker, together with NIHSS and pc-ASPECTS scores of AIS patients.

Conclusions: NORAD was upregulated in AIS, which can discriminate AIS patients, and was closely correlated with severe development and poor prognosis of patients.

Introduction: In recent years, novel RNAs have been revealed to be regulators in glioma. ADAMTS8 has been reported to be reduced in brain tumours. In this study, we aimed to explore the role of ADAMTS8 in glioma.

Material and methods: Online bioinformatic tools, Gepia and Chinese Glioma Genome Atlas database (CGGA) were used to analyse the differential expression of ADAMTS8, overall survival and disease-free survival rates and the correlations between ADAMTS8 and matrix metallopeptidases (MMP2 and MMP9) in glioma. RT-qPCR and western blot experiments were performed to measure the mRNA and protein expression. ADAMTS8 expression was regulated in cells through transfection. Thereafter, the effect of ADAMTS8 on cells was investigated through the cell viability, apoptosis and transwell experiments. The epithelial-mesenchymal transition (EMT)-related proteins and also MMP2 and MMP9 were examined. The subcutaneous tumour model was established to validate the suppressive role of ADAMTS8 in tumour growth.

Results: ADAMTS8 expression was reduced in glioma tissues and cells. Higher expression of ADAMTS8 was correlated with higher survival rates. ADAMTS8 was correlated with MMP2 and MMP9 in glioma tissues. In glioma cells, overexpression of ADAMTS8 could inhibit the viability, invasion, migration and EMT, and MMP2 and MMP9, but promote the apoptosis of cells. The upregulation of ADAMTS8 could inhibit the tumour growth in vivo.

Conclusions: ADAMTS8 was inhibited in glioma and the higher expression of ADAMTS8 might be related to better prognosis among glioma patients. Overexpression of ADAMTS8 inhibited the development of glioma in vitro and in vivo.

近年来,新的rna被发现在胶质瘤中起调节作用。据报道,ADAMTS8在脑肿瘤中减少。在这项研究中,我们旨在探讨ADAMTS8在胶质瘤中的作用。材料和方法:利用在线生物信息学工具Gepia和中国胶质瘤基因组图谱数据库(CGGA)分析胶质瘤中ADAMTS8的差异表达、总生存率和无病生存率以及ADAMTS8与基质金属肽酶(MMP2和MMP9)的相关性。RT-qPCR和western blot检测mRNA和蛋白的表达。转染后,ADAMTS8在细胞中表达得到调控。随后,通过细胞活力、凋亡和transwell实验研究ADAMTS8对细胞的影响。检测上皮-间质转化(epithelial-mesenchymal transition, EMT)相关蛋白以及MMP2和MMP9。建立皮下肿瘤模型,验证ADAMTS8对肿瘤生长的抑制作用。结果:ADAMTS8在胶质瘤组织和细胞中表达降低。ADAMTS8的高表达与较高的存活率相关。在胶质瘤组织中,ADAMTS8与MMP2、MMP9相关。在胶质瘤细胞中,过表达ADAMTS8可抑制细胞活力、侵袭、迁移和EMT,抑制MMP2和MMP9,但促进细胞凋亡。上调ADAMTS8可抑制肿瘤在体内的生长。结论:ADAMTS8在胶质瘤中受到抑制,ADAMTS8的高表达可能与胶质瘤患者预后较好有关。在体内和体外,过表达ADAMTS8抑制胶质瘤的发生。

Introduction: CD8 + T-cells and MHC-I have been detected in brain gliomas with a significant outcome. The effect of chemotherapies on the crosstalk interaction between CD8 + T-cells and MHC-I has never been explored.

Material and methods: The protein expression profiling of CD8 cytotoxic T-cells and the gene expression assay of MHC-I in 35 patients diagnosed with WHO grade 4 astrocytoma were performed. The impact of these two factors on tumor recurrence was analyzed.

Results: IDH was wildtype in 13 tumors. MHC-I protein expression was absent or low in 34 tumors and dense in a single case. MHC-I gene expression was upregulated in 10 tumors and 25 tumors showed MHC-I gene downregulation. Temozolomide (TMZ) was given to 24 patients and 11 patients received TMZ plus other chemotherapies. No statistically significant association was observed between IDH mutation and CD8 + T-cells ( p = 0.383). However, this association was significant in recurrence-free interval (RFI) ( p = 0.012). IDH-wildtype tumors with highly infiltrated CD8 + T-cells or IDH-mutant tumors with low CD8 + T-cells showed late tumor recurrence. There was a statistically significant difference in RFI between tumors with different MHC-I expression and CD8 + T-cell counts after treatment with TMZ or TMZ plus ( p = 0.026).

Conclusions: No association between IDH mutation and CD8+ cytotoxic T-cell was found. IDH is directly linked to tumor recurrence regardless of CD8 + T-cells infiltration. TMZ plus other adjuvants is proved to be more effective in improving patient survival and delaying tumor recurrence, as compared to using TMZ alone. Nonetheless, none-TMZ adjuvants may increase tumor sensitization to cytotoxic T-cells more than TMZ.

引言:在脑胶质瘤中检测到CD8+T细胞和MHC-I,结果显著。化疗对CD8+T细胞和MHC-I之间串扰相互作用的影响从未被探索过。材料与方法:对35例世界卫生组织4级星形细胞瘤患者进行了CD8细胞毒性T细胞的蛋白表达谱分析和MHC-I基因表达测定。分析了这两个因素对肿瘤复发的影响。结果:IDH在13例肿瘤中为野生型。MHC-I蛋白表达在34个肿瘤中缺失或低,在单个病例中密集。MHC-I基因表达在10例肿瘤中上调,25例肿瘤MHC-I表达下调。替莫唑胺(TMZ)用于24例患者,11例患者接受TMZ加其他化疗。在IDH突变和CD8+T细胞之间没有观察到统计学上显著的相关性(p=0.383)。然而,这种相关性在无复发间隔期(RFI)中显著(p=0.012)。具有高度浸润CD8+T淋巴细胞的IDH野生型肿瘤或具有低CD8+T细胞的IDH突变型肿瘤显示出晚期肿瘤复发。不同MHC-I表达的肿瘤在TMZ或TMZ+治疗后的RFI和CD8+T细胞计数之间存在统计学显著差异(p=0.026)。IDH与肿瘤复发直接相关,而与CD8+T细胞浸润无关。与单独使用TMZ相比,TMZ加其他佐剂被证明在提高患者生存率和延缓肿瘤复发方面更有效。尽管如此,没有一种TMZ佐剂比TMZ更能增加肿瘤对细胞毒性T细胞的敏感性。

Parkinson's disease (PD) is a chronic neuronal loss of dopamine and drugs used for its management has several limitations. The present report determines the effect of exercise on mitochondrial autophagy against PD. Parkinson's disease was induced by 15 doses of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP; 30 mg/kg, i.p.) for 3 weeks, on five consecutive days in a week. Exposure of exercise was provided for 40 min for a period of 2 weeks after PD confirmation. Assessment of behaviour was performed to evaluate the effect of exercise on motor function and cognitive function in PD rats. Levels of reactive oxygen species (ROS) and inflammatory cytokines were assessed in PD rats using enzyme linked immunosorbent assay (ELISA). Expression of myocyte-specific enhancer factor 2D (MEF2D) and NADH dehydrogenase 6 (ND6) was estimated in PD rats. Exposure to exercise ameliorates the altered motor function and cognitive function in PD rats. There was a reduction in ROS and cytokine levels in the brain tissue of the exercise group compared to the negative control group. Exercise ameliorates the altered expression of apoptotic proteins and mRNA expression of MEF2D and ND6 in the brain tissue of MPTP induced PD rats. In conclusion, data of study reveal that exercise protects the mitochondrial autophagy in PD rats by reducing inflammatory cytokines and oxidative stress.

帕金森病(Parkinson's disease,PD)是一种多巴胺慢性神经元缺失症,用于治疗该病的药物有多种局限性。本报告确定了运动对帕金森病线粒体自噬的影响。帕金森病是由 15 剂 1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP;30 毫克/千克,静脉注射)诱发的,持续 3 周,一周内连续 5 天。在确诊帕金森病后的两周内,进行了为期 40 分钟的运动。对行为进行评估,以评价运动对帕金森病大鼠运动功能和认知功能的影响。使用酶联免疫吸附试验(ELISA)评估了帕金森病大鼠体内活性氧(ROS)和炎症细胞因子的水平。还估测了帕金森病大鼠肌细胞特异性增强因子2D(MEF2D)和NADH脱氢酶6(ND6)的表达。运动能改善帕金森病大鼠运动功能和认知功能的改变。与阴性对照组相比,运动组脑组织中的 ROS 和细胞因子水平有所降低。运动可改善MPTP诱导的帕金森病大鼠脑组织中凋亡蛋白表达的改变以及MEF2D和ND6的mRNA表达。总之,研究数据显示,运动可通过减少炎症细胞因子和氧化应激来保护帕金森病大鼠线粒体的自噬功能。
