Novel circRNA_103758-miRNA-19b-3p-CIT axis is associated with proliferation and migration of bladder cancer via RhoA-ROCK signaling pathway [RNA-seq]

ABSTRACT: Purpose:The purpose of this study is to investigate the potential mechanisms that triggering the onset of bladder cancer and to screen differential expressed genes. Methods: We screened differentially expressed genes with the data obtained from RNA-seq on Bladder carcinoma samples and matched normal samples. Functional annotation analysis and protein-protein interaction (PPI) network were performed to investigate the potential key pathways and genes that play significant roles in BCa. Furthermore, the ceRNA network was established and the Gene Set Enrichment Analysis (GSEA) was executed to dig key circRNAs. Results: Following the identification of differentially expressed genes, functional annotation analysis was conducted, suggesting that differentially expressed mRNAs (DEMs) were mainly involved in cell cycle related pathways. The top 11 genes with the highest degree were extracted from PPI network. The predicted regulatory relationships among the differentially expressed genes were found and the ceRNA network was established. Finally, GSEA was conducted on the circRNAs and the key biological pathways were identified. Conclusion: Our study is the pioneering research to analyze the pathogenesis of BCa with integrated informatics and we have identified several hub genes, which reveals that the generation of BCa is closely related to cell cycle.

Construction of a ceRNA network and screening of potential biomarkers and molecular targets in male smokers with chronic obstructive pulmonary disease

Project description:Background. Circular RNAs (circRNAs) play an important role in the occurrence and development of diseases. However, the role of circRNAs in male smokers with chronic obstructive pulmonary disease (COPD) remains unclear. Methods. Stable COPD patients and healthy controls were recruited. Peripheral blood mononuclear cells (PBMCs) were extracted. After high-throughput RNA sequencing (RNA-Seq) of PBMCs, a bioinformatics method was used to analyse differentially expressed (DE) circRNAs (DEcircRNAs) and mRNAs (DEmRNAs). Results. Total of 114 DEcircRNAs and 58 DEmRNAs were identified. Functional enrichment analysis showed that processes related to COPD include the regulation of interleukin (IL)-18, IL-5 and the NLRP3 inflammasome; differentiation of T helper type 1 (Th1), Th2, and Th17 cells, and the AMPK, Wnt, JAK-STAT, and PI3K-Akt signalling pathways. In the protein–protein interaction (PPI) network, the core genes were MYO16, MYL4, SCN4A, NRCAM, HMCN1, MYOM2, and IQSEC3. Small-molecule prediction results revealed potential drugs for the COPD treatment. Additionally, the circRNA-miRNA-mRNA competitive endogenous RNA (ceRNA) regulatory network was constructed. Conclusion. This study identified a set of dysregulated circRNAs and mRNAs and revealed potentially important genes, pathways, new small-molecule drugs and ceRNA regulatory networks in male smokers with COPD. These circRNAs might be prospective biomarkers or potential molecular targets of the ceRNA mechanism for COPD.

Differentially-expressed mRNAs, microRNAs and long noncoding RNAs in intervertebral disc degeneration identified by RNA-sequencing

Project description:This study aimed to identify the crucial molecules and explore the function of noncoding RNAs and related pathways in IDD. We randomly selected 3 samples each from an IDD and a spinal cord injury group (control) for RNA-sequencing. We identified 463 differentially-expressed long noncoding RNAs (lncRNAs), 47 differentially-expressed microRNAs (miRNAs), and 1,334 differentially-expressed mRNAs in IDD. Three hundred fifty-eight lncRNAs as cis-regulators could potentially target 865 genes. Protein–protein interaction (PPI) network analysis confirmed that IL-6, VEGFA, IGF1, MMP9, CXCL8, FGF2, IL1B, CCND1, ITGAM, PTPRC, FOS and PTGS2 were hub genes. We built a competing endogenous RNA (ceRNA) network and identified lncRNA XIST–hsa-miR-4775–PLA2G7 and lncRNA XIST–hsa-miR-424-5p–AMOT/TGFBR3 ceRNA axes.

Comprehensive analysis of circRNA expression profiles and circRNA associated competing endogenous RNA networks in IgA nephropathy

Project description:Purpose: Immunoglobulin A nephropathy (IgAN) is immune-mediated primary glomerulonephritis, which is the most common reason leading to renal failure worldwide, the exact pathogenesis of IgAN is not well defined. Accumulating evidence indicates that circular RNAs (circRNAs) play crucial roles in the immune disease by involving in the competing endogenous RNA (ceRNA) network mechanism. At present, the studies of the circRNA profiles and circRNA-associated ceRNA networks in the IgAN are still scarce. This study aimed to elucidate the potential roles of circRNA, microRNA (miRNA), and messenger RNA (mRNA) ceRNA network in peripheral blood mononuclear cells (PBMCs) of IgAN. Methods: CircRNA sequencing was used to identify the differential expressed circRNAs (DEcircRNAs) of PBMCs in IgAN and healthy controls. A circRNA-miRNA-mRNA ceRNA network was constructed to further investigate the mechanisms of IgAN. Results: A total of 145 circRNAs were differentially expressed in IgAN compared with controls (|log2 (FC)|>1 and P-value <0.05). Combined with the data from GSE73953 and GSE25590 in GEO database, a ceRNA network was constructed which contained 16 DEcircRNAs, 72 differential expressed mRNAs (DEmRNAs) and 11 differential expressed miRNAs (DEmiRNAs). Conclusion: Our study identified a novel circRNA-mediated ceRNA regulatory network mechanisms in the pathogenesis of IgAN.

LncRNA and circRNA expression profiles of Aβ25-35-induced AD mice hippocampus treated with Tripterygium Glycoside

Project description:Tripterygium glycosides (TG) was reported to have effect of ameliorating Alzheimer's disease (AD). However, the mechanism is not clear. We aimed to investigate the lncRNAs and circRNAs expression profiles of AD treated with TG by using microarray. LncRNAs, mRNA and circRNA in 3 AD mice and 3 AD+TG mice hippocampal were detected by microarray. The most differentially expressed lncRNAs, mRNA and circRNA in AD+TG group were screened. The differentially expressed lncRNAs and circRNAs were analyzed for GO enrichment and KEGG pathway. Co-expression analysis of lncRNAs and mRNA was performed by calculating correlation coefficients. Protein-protein interaction (PPI) network analysis was performed on mRNAs using STRING. LncRNA-target-TFs network were analyzed by Network software. CircRNA-mirNA network were conducted by Cytoscape software. A total of differentially expressed 661 lncRNAs, 64 circRNAs and 503 mRNAs were detected in AD mice treated with TG. The Pou4f1, Egr2, Mag, and Nr4a1 were the hub genes in the PPI network. The KEGG results showed the mRNAs that co-expressed with lncRNAs were enriched in TNF, PI3K-Akt, and Wnt signaling pathway. lncRNA-target-TFs network analysis indicated the TFs including Cebpa, Zic2, and Rxra were the most likely to regulate the detected lncRNAs. The circRNA-miRNA interaction network indicated 275 miRNAs may bind to the 64 circRNAs. In conclusion, the findings supplied a novel perspective for AD pathogenesis. And the detected lncRNAs, mRNAs, and circRNAs might be novel therapeutics targets for AD.

Identification of a novel set of DNA methylation markers in bladder cancer using MBD-methylCap/seq and urine DNA screening in a Chinese population

Project description:The aim of the present study was to identify novel DNA methylation markers in bladder cancer (BCa) through genome-wide profiling of bladder cancer cell lines and subsequent MSP screening in urine samples. Experimental Design: MBD methylCap/seq was carried out to screen differentially methylated CpG islands using two BCa cell lines (5637 and T24) and two normal bladder mucosa (BM) samples. The top one hundred most hypermethylated targets were screened using Methylation Specific PCR (MSP) in small and big cohort of urine samples from BCa patients and normal controls. The diagnostic performance of the gene panel was further evaluated in different clinical scenarios. Results: In total, 1,627 gene promoter regions hypermethylated in BCa cell line were identified in genomic level methylation profiling. The followed screening procedure in clinical urine sample generated eight genes (VAX1, KCNV1, ECEL1, TMEM26, TAL1, PROX1, SLC6A20, and LMX1A) capable of differentiating BCa from normal control. Subsequent validation in a large sample size enabled the optimisation of 5 methylation targets (VAX1, KCNV1, TAL1, PPOX1 and CFTR) for BCa diagnosis with sensitivity and specificity of 86.32% and 87.13%, respectively. In addition, VAX1 and LMX1A methylation could predict the tumour recurrence. Conclusions: Tumor specific biomarkers of BCa could be established by first performing genome level methylation profiling with cell lines and then screening the potential targets in urine samples. The panel of methylated genes identified was promising for the early non-invasive detection and surveillance of BCa. MBD methylCap/seq was carried out to screen differentially methylated CpG islands using two BCa cell lines (5637 and T24), and two normal bladder tissue mix as control.

Analyzing the interactions of mRNAs, miRNAs, lncRNAs and circRNAs to predict competing endogenous RNA networks in glioblastoma

Project description:Cross-talk between competitive endogenous RNAs (ceRNAs) may play a critical role in revealing potential mechanisms of tumor development and physiology. Glioblastoma is the most common type of malignant primary brain tumor, and the mechanisms of tumor genesis and development in glioblastoma are unclear. Here, to investigate the role of non-coding RNAs and the ceRNA network in glioblastoma, we performed paired-end RNA sequencing and microarray analyses to obtain the expression profiles of mRNAs, lncRNAs circRNAs and miRNAs. We identified that the expression of 501 lncRNAs, 1789 mRNAs, 2038 circRNAs and 143 miRNAs were often altered between glioblastoma and matched normal brain tissue. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed on these differentially expressed mRNAs and miRNA-mediated target genes of lncRNAs and circRNAs. Furthermore, we used a multi-step computational framework and several bioinformatics methods to construct a ceRNA network combining mRNAs, miRNAs, lncRNAs and circRNA, based on co-expression analysis between the differentially expressed RNAs. We identified that plenty of lncRNAs, CircRNAs and their downstream target genes in the ceRNA network are related to glutamatergic synapse, suggesting that glutamate metabolism is involved in glioma biological functions. Our results will accelerate the understanding of tumorigenesis, cancer progression and even therapeutic targeting in glioblastoma. We hope to inspire researchers to study the role of non-coding RNAs in glioblastoma.
