Abstract Background: Prostate cancer (PC) is one of the most common malignant tumors. Recently, it has been reported that long noncoding RNAs (lncRNAs) play key roles in tumor progression. Studies have revealed that long non-coding RNA CAR10 (CAR10) can regulate tumor cell behaviors through sponging miR-203. In this study, we examined the effects of CAR10 in PC cells. Methods: Firstly, real time-quantitative polymerase chain reaction (qRT-PCR) was used to explore CAR10 expression in tumor tissues, peripheral blood of PC patients, and PC cells. We used the dual-luciferase reporter gene assay to analyze the relationship between CAR10 and miR-203. Moreover, flow cytometry, MTT assay, and western blot assay were used to determine cell apoptosis, cell viability, and apoptosis-related protein expression. Results: The results showed that CAR10 expression was remarkably higher in PC samples compared with that of control, and CAR10 regulated miR-203 negatively in PC cells. The qRT-PCR results also showed that miR-203 expression was significantly decreased in PC samples. Moreover, knockdown of CAR10 inhibited PC cell viability and promoted cleaved caspase-3 expression but induced PC cell apoptosis and, reduced pro-caspase-3 expression; miR-203 inhibitor reversed these effects. Conclusion: Our study found that CAR10 is a potential oncogene in PC and suggests that CAR10 inhibition could inhibit PC cell viability but promote PC cell apoptosis through regulating miR-203 expression. Our results show that CAR10 is a potential target for the treatment of PC.

Abstract Background Both long non-coding RNA (lncRNA) NEAT1 and microRNA (miR)-139 are crucial gene regulators in various disorders. This study aims to investigate their role in epilepsy and seizure-induced neuronal damage. Methods In this research, rat model of epilepsy was established by pilocarpine induction. The RNA and protein expression in hippocampal tissues and neurons were determined by RT-qPCR and Western blot analysis, respectively. Microarray analysis was used to predict the relationship between NEAT1 and miR-139 or between miR-139 and ROCK1, and dual luciferase reporter gene assay was performed to verify the interaction. The endogenous expression of related genes was modulated by recombinant plasmids and cell transfection. The cell apoptosis, levels of inflammatory factors and cell proliferation were detected by flow cytometry, ELISA and EdU assay. Results LncRNA NEAT1 and ROCK1 was upregulated, while the miR-139 was downregulated in hippocampal tissues and neurons of epileptic rats. Overexpression of NEAT1 decreased the activity of neurons, increased cell apoptosis, and increased the level of inflammatory factors. NEAT1 negatively targeted miR-139 to upregulate ROCK1. The RhoA/ROCK1 signaling pathway was activated by NEAT1 overexpression and miR-139 downregulation. Conclusion LncRNA NEAT1 suppressed pilocarpine-induced epilepsy by inhibiting apoptosis of hippocampal neurons through miR-139/RhoA/ROCK1 axis, and thereby inhibiting neuronal injury induced by seizure.

The current study aimed to explore the role and mechanism of microRNA-425-5p (miR-425-5p) in hypertrophic scar (HS) development. Firstly, we used reverse transcription-quantitative polymerase chain reaction (qRT-PCR)to detect the expression of miR-425-5p in human hypertrophic scar fibroblasts (hHSFs) and HS tissues. qRT-PCR assay showed that miR-425-5p level significantly down-regulated in HS tissues and hHSFs. Next, we performed TargetScan and dual-luciferase reporter assay to predict and verify Smad2 was the target gene of miR-425-5p. In order to determine the role of miR-425-5p in HS formation, miR-425-5p was over-expressed or knockdown in hHSFs through transfection with miR-425-5p mimic or miR-425-5p inhibitor. CCK-8 assay and cell apoptosis analysis were carried out to measure cell viability and apoptosis. Protein expression was assessed by Western blotting. The findings indicated that miR-425-5p mimic transfection inhibited cell viability, promoted cell apoptosis and repressed Smad2, Col I, and Col III expression in hHSFs. Notably, the transfection of Smad2-plasmid eliminated the effects of miR-425-5p mimic on hHSFs. However, miR-425-5p inhibitor transfection had opposite effects on hHSFs, and were eliminated by the transfection of Smad2-siRNA. In conclusion, these findings suggested that miR-425-5p inhibited the hHSFs viability, induced hHSFs apoptosis and repressed extracellular matrix deposition of hHSFs through regulating Smad2. Therefore, miR-425-5p might be a novel therapeutic target for HS treatment.

Background: Prostate cancer (PCa) is a commonly diagnosed malignant cancer and is the second highest cause of cancer related death in men worldwide. Enzalutamide is the second-generation inhibitor of androgen receptor signaling and is the fundamental drug for the treatment of advanced PCa. However, the disease will eventually progress to metastatic castration-resistant prostate cancer (CRPC) and aggressive neuroendocrine prostate cancer (NEPC) because of androgen-deprivation therapy (ADT) resistance. The aim of the study was to investigate the role of long non-coding RNA (lncRNA) AFAP1-AS1 in ADT resistance. Objective: Quantitative real-time PCR analysis (qPCR) was used to assess the expression of AFAP1-AS1 in PCa cell lines and tissues. Cell proliferation and invasion were assessed after AFAP1-AS1 knockdown using Cell Counting Kit (CCK)-8 and Transwell assay, respectively. A dual-luciferase reporter gene assay was carried out to validate the regulatory relationship among AFAP1-AS1, microRNA (miR)-15b, and insulin-like growth factor1 receptor (IGF1R). Results: AFAP1-AS1 level was markedly increased in castration-resistant C4-2 cells and NE-like cells (PC3, DU145, and NCI-H660), compared with androgen-sensitive LNCaP cells. Enzalutamide treatment increased the expression of AFAP1-AS1 in vitro and in vivo. Functionally, AFAP1-AS1 knockdown repressed tumor cell proliferation and invasion. Mechanistically, AFAP1-AS1 functioned as an oncogene in PCa through binding to miR-15b and destroying its tumor suppressor function. Finally, we identified that AFAP1-AS1 up-regulated IGF1R expression by competitively binding to miR-15b to de-repress IGF1R. Conclusion: AFAP1-AS1 facilitates PCa progression by regulating miR-15b/IGF1R axis, indicating that AFAP1-AS1 may serve as a diagnostic biomarker and therapeutic target for PCa.

IntroductionCarotid atherosclerosis (CAS) is one of the main causes of cerebral infarction in the ageing population. Long non-coding RNA small nucleolar RNA host gene 16 (lnc-SNHG16) could promote the development of atherosclerosis. However, the mechanism of lnc-SNHG16 in CAS remains vague.Material and methodsThe expression levels of lnc-SNHG16, microRNA-30c-5p (miR-30c-5p) and disintegrin and metalloproteinase 10 (ADAM10) were detected by real-time quantitative polymerase chain reaction (RT-qPCR). Cell viability and migration were detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) and transwell assays, severally. The levels of interleukin-6 (IL-6), IL-β and tumor necrosis factor-α (TNF-α) were assessed by enzyme-linked immunosorbent assay (ELISA). Protein levels of spinal muscular atrophy (SMA), calponin and ADAM10 were examined by western blot assay. The binding relationship between miR-30c-5p and lnc-SNHG16 or ADAM10 was predicted by Starbase, then verified by the dual-luciferase reporter assay.ResultsLnc-SNHG16 and ADAM10 were increased, and miR-30c-5p was decreased in CAS patient and oxidized low-density lipoprotein (ox-LDL)-treated human aortic smooth muscle cells (hASMCs). Lnc-SNHG16 silencing repressed cell viability, migration, inflammation, facilitated differentiation in ox-LDL-treated hASMCs. Moreover, mechanical analysis proved that lnc-SNHG16 improved ADAM10 expression by sponging miR-30c-5p.ConclusionsOur data indicated that lnc-SNHG16 could regulate the progression of ox-LDL induced CAS model by the miR-30c-5p/ADAM10 axis, implying a potential therapeutic strategy for CAS

Background: Prostate cancer is a common malignant tumor with a high incidence. MicroRNAs (miRNAs) have been shown to be important post-transcriptional regulators during tumorigenesis. This study aimed to explore the effect of miR-144 on PCa proliferation and apoptosis. Material and Methods: The expression of miR-144 and EZH2 were examined in clinical PCa tissues. PCa cell line LNCAP and DU-145 was employed and transfected with miR-144 mimics or inhibitors. The correlation between miR-144 and EZH2 was verified by luciferase reporter assay. Cell viability, apoptosis and migratory capacity were detected by CCK-8, flow cytometry assay and wound healing assay. The protein level of EZH2, E-Cadherin, N-Cadherin and vimentin were analyzed by western blotting. Results: miR-144 was found to be negatively correlated to the expression of EZH2 in PCa tissues. Further studies identified EZH2 as a direct target of miR-144. Moreover, overexpression of miR-144 downregulated expression of EZH2, reduced cell viability and promoted cell apoptosis, while knockdown of miR-144 led to an inverse result. miR-144 also suppressed epithelial-mesenchymal transition level of PCa cells. Conclusion: Our study indicated that miR-144 negatively regulate the expression of EZH2 in clinical specimens and in vitro. miR-144 can inhibit cell proliferation and induce cell apoptosis in PCa cells. Therefore, miR-144 has the potential to be used as a biomarker for predicting the progression of PCa.

Background/Aims: To investigate the biological roles and underlying molecular mechanisms of long non-coding RNA (lncRNA) PVT1 in Hepatocellular carcinoma (HCC). Methods: qRT-PCR was performed to measure the expression of miRNA and mRNA. Western blot was performed to measure the protein expression. CCK-8 assay was performed to determine cell proliferation. Flow cytometry was performed to detect cell apoptosis. Wounding-healing assay and Transwell assay was performed to detect cell migration and invasion. Dual luciferase reporter assay was performed to verify the target relationship. Quantichrom iron assay was performed to check uptake level of cellular iron. Results: PVT1 expression was up-regulated in HCC tissues and cell lines. Function studies revealed that PVT1 knockdown significantly suppressed cell proliferation, migration and invasion, and induced cell apoptosis in vitro. Furthermore, PVT1 could directly bind to microRNA (miR)-150 and down-regulate miR-150 expression. Hypoxia-inducible protein 2 (HIG2) was found to be one target gene of miR-150, and PVT1 knockdown could inhibit the expression of HIG2 through up-regulating miR-150 expression. In addition, the expression of miR-150 was down-regulated, while the expression of HIG2 was up-regulated in HCC tissues and cell lines. Moreover, inhibition of miR-150 could partly reverse the biological effects of PVT1 knockdown on proliferation, motility, apoptosis and iron metabolism in vitro, which might be associated with dysregulation of HIG2. In vivo results showed that PVT1 knockdown suppressed tumorigenesis and iron metabolism disorder by regulating the expression of miR-150 and HIG2. Conclusion: Taken together, the present study demonstrates that PVT1/miR-150/HIG2 axis may lead to a better understanding of HCC pathogenesis and provide potential therapeutic targets for HCC.

Allergic rhinitis (AR) is a type I hypersensitive disease. Long non-coding RNA (lncRNA) SNHG16 acts as an oncogene in a variety of tumors and promotes the occurrence of inflammation in many inflammatory diseases. The study aims to investigate the expression of SNHG16 and its potential biological functions in AR. RT-qPCR results showed that the expression of SNHG16 in AR was up-regulated. The AR cell model was constructed by stimulating primary nasal mucosal epithelial cells from AR patients with IL-13. After knocking down the expression of lncRNA SNHG16, cell apoptosis was detected by flow cytometry, and the expression of inflammatory factors was detected by ELISA. The results showed that SNHG16 promoted cell apoptosis and inflammation. Then, bioinformatics analysis was used to screen miRNAs bound with SNHG16. Luciferase reporter gene assay and RNA pull-down experiment were used to verify the relationship. We found that the expression of miR-106b-5p was down-regulated and leukemia inhibitory factor (LIF) expression was up-regulated in the AR cell model. The expression of phospho-Janus kinase 1 and p-signal transducer and activator of transcription 3 (STAT3) were detected by Western blotting. Silencing the expression of LIF could inhibit the activity of JAK1/STAT3 pathway and further inhibit cell apoptosis and the occurrence of inflammation. Then transfected SNHG16 shRNA alone or together with miR-106b-5p antagomir into the AR cell model, we found that silencing the expression of SNHG16 down-regulated the expression of LIF and inhibited the activity of the JAK1/STAT3 pathway, cell apoptosis, and inflammation. However, miR-106b-5p antagomir weakened its inhibitory effects. The role of SNHG16 in AR was further verified by the ovalbumin-induced AR mouse model in vivo. In conclusion, SNHG16 up-regulates LIF expression by binding with miR-106b-5p, thus promoting the activity of JAK1/STAT3 pathway, and promoting the development of AR. These results provide new targets for the treatment of AR and may help reduce the damage caused by AR.

PurposeColon cancer-associated transcript 1 (CCAT1) was identified as an oncogenic long non-coding RNA (lncRNA) in a variety of cancers. However, there was a lack of understanding of the mechanism by which CCAT1 conferred cisplatin (also known as DDP) resistance in ovarian cancer cells.Materials and MethodsCell viability of A2780, SKOV3, A2780/DDP, and SKOV3/DDP cells upon cisplatin treatment was monitored by MTT assay. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) detected the expression levels of CCAT1 and miR-454. The effect of sh-CCAT1 on cisplatin response was investigated in xenografts study. Bioinformatic analysis, luciferase reporter assay and qRT-PCR were conducted to validate the direct interaction among CCAT1, miR-454, and survivin. Apoptosis was determined by flow cytometry after dual staining of Annexin-V-FITC/propidium iodide, and the expression of apoptosis-related proteins Bcl-2, Bax and survivin were detected by qRT-PCR and Western blotting. Xenograft study was conducted to monitor <i>in vivo</i> tumor formation.ResultsCCAT1 was highly expressed in cisplatin-resistant ovarian cancer cell line A2780/DDP and SKOV3/DDP. Knockdown of CCAT1 restored sensitivity to cisplatin <i>in vitro</i> and <i>in vivo</i>. Our data revealed that silencing of CCAT1 promoted cisplatin-induced apoptosis via modulating the expression of pro- or anti-apoptotic proteins Bax, Bcl-2, and survivin. CCAT1 directly interacted with miR-454, and miR-454 overexpression potentiated cisplatin-induced apoptosis. Survivin was identified as a functional target of miR-454, restoration of survivin attenuated the effect of miR-454 on cisplatin response. In addition, miR-454 inhibitor or overexpression of survivin was found to abolish sh-CCAT1–induced apoptosis upon cisplatin treatment.ConclusionCCAT1/miR-454/survivin axis conferred cisplatin resistance in ovarian cancer cells.

Abstract BackgroundCerebral ischemic stroke was a nervous system disease with high occurrence rate and mortality rate. This study aimed to investigate the role and mechanism of lncRNA WT1-AS in cerebral ischemic stroke. Materials and methodsStarbase and dual luciferase reporter gene assay were used to analyze the target relationship between lncRNA WT1-AS and miR-186-5p. qRT-PCR analysis was used to detect lncRNA WT1-AS and miR-186-5p expression. OGD-induced SH-SY5Y cells injury model was conducted, and cell viability and cell apoptosis were determined by MTT and flow cytometer assay. Caspase3 ability was determined using Caspase3 activity detection kit. ResultsmiR-186-5p was a target of lncRNA-WT1-AS. lncRNA WT1-AS was down-regulated and miR-186-5p was up-regulated in blood samples of patients with ischemic stroke and in OGD-induced SH-SY5Y cells. We found that WT1-AS-plasmid promoted OGD-induced cell viability, reduced cell apoptosis and decreased caspase3 ability, and these changes were reversed by miR-186-5p mimic. Subsequently, our results proved that XIAP was a target of miR-186-5p. Similarly, miR-186-5p inhibitor reduced OGD-induced neuronal damage by up-regulating XIAP expression. ConclusionlncRNA-WT1-AS/miR-186-5p/XIAP might be a new target for cerebral ischemic stroke treatment.
