Global analysis of circRNA-associated ceRNA network for investigating underlying pathogenesis of constrictive pericarditis (miRNA-Seq)

Project description:Purpose:The purpose of this study is to investigate the potential mechanisms that triggering the onset of constrictive pericarditis and to screen hub genes that exert impact on pathogenesis of patients with constrictive pericarditis. Methods: We screened differentially expressed genes with the data obtained from RNA-seq on CP 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 CP. 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 inflammatory response related pathways. The top 11 genes with the highest degree were extracted from PPI network. A total of 377 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 CP with integrated informatics and we have identified several hub genes, which reveals that the generation of CP is closely related to inflammation and fibrosis.

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.

Whole-transcriptomic analysis of circRNA-miRNA-mRNA ceRNA network in 4-month APP/PS1 mouse hippocampus

Project description:Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, and the molecular mechanisms of AD remain unclear. Accumulating evidence indicates the involvement of non-coding RNAs in AD pathogenesis. Here, we applied RNA-seq to explore the expression changes of circRNA, miRNA, and mRNA simultaneously, and investigate competing endogenous RNA (ceRNA) networks in hippocampus of 4-month APP/PS1 and wild-type mice.

Comprehensive Dissection of CircRNA-Associated-ceRNA Networks in Cardiac Transplant Rejection Immunity

Project description:Transplant rejection is a major factor limiting allograft survival. CircRNAs are reported to be strongly associated with various diseases pathogenesis. However, the potential role of circRNAs in cardiac transplant rejection are rarely reported. Here, differentially expressed mRNAs and circRNAs were determined by microarrays in allogeneic cardiac allografts. Functional analysis was then performed and a full-scale functional blueprint of the circRNA-associated-ceRNA networks was constructed. Among the circRNA networks, circ23123 expression was negatively linked with cytolytic molecules of CD8+ T cells by targeting miR155-SOCS1 axis. We illustrated a new comprehensive view of circRNAs and their potential functional impact in cardiac transplantation. It may provide a prospective for therapeutic strategy on organ transplant rejection in the future.

Comprehensive circRNA expression profile and construction of circRNAs-related ceRNA network in a mouse model of autism

Project description:Purpose: We aimed to detected the circRNA expression profile and constructed a circRNA-based competing endogenous RNA (ceRNA) network in autism. Methods:Valproate acid was used to establish an in vivo model of autism in mice. circRNAs in autism group was identified by RNA sequencing. The expression of circRNAs were detected by real-time PCR. Module analysis was conducted followed by GO and KEGG pathway enrichment analysis. Results: A total of 1059 differentially expressed circRNAs (477 upregulated and 582 downregulated) in autism group. The expression of novel_circ_015779 and novel_circ_035247 were detected by real-time PCR. A ceRNA network based on altered circRNAs was established, with 9715 nodes and 150408 edges. The top three modules were all correlated with autism-related pathways involving ‘TGF-beta signaling pathway’, ‘Notch signaling pathway’, ‘MAPK signaling pathway’, ‘long term depression’, ‘thyroid hormone signaling pathway’, etc. Conclusions: The present study reveals a novel circRNA involved mechanisms in the pathogenesis of autism.

Identification of circRNA-interacting proteins in pancreatic ductal adenocarcinoma

Project description:Many studies have demonstrated the importance of circRNA in regulating gene expression through functioning as microRNA sponges. However, the roles of circRNA-protein interaction are not fully understood. Importantly, how circRNA-protein interaction contributes the progression of pancreatic ductal adenocarcinoma is largely unexplored. Therefore, RNA Pull down assay for investigating RNA-protein interaction was performed in PANC-1 cells.
