Transcriptomic analysis of gastric cancer cells in response to stable over-expression of circular RNA derived from CTNNB1 gene (circ-CTNNB1)

ABSTRACT: Circular RNAs (circRNAs), a subclass of noncoding RNAs characterized by covalently closed continuous loops, play emerging roles in tumorigenesis and aggressiveness. However, the functions and underlying mechanisms of circRNAs in regulating the Wnt/β-catenin signaling and cancer progression still remain elusive. We identify one intronic circRNA derived from CTNNB1 (circ-CTNNB1) as a novel driver of cancer progression. To investigate the mechanisms underlying the oncogenic functions of circ-CTNNB1, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human gastric cancer AGS cells in response to stable over-expression of circ-CTNNB1. The results showed that stable over-expression of circ-CTNNB1 led to altered expression of 2230 human mRNAs, including 1244 up-regulated genes and 986 down-regulated genes. Furthermore, we validated the RNA-seq results by real-time RT-PCR with high identity. Overall, our results provided fundamental information about the transcriptomic changes in response to circ-CTNNB1 over-expression in human cancer cells, and these findings will help us understand the pathogenesis of cancer progression.

Transcriptomic analysis of gastric cancer cells in response to stable over-expression of circRNA derived from hnRNPU (circ-hnRNPU)

Project description:Circular RNA (circRNA) is a type of endogenous single-stranded and covalently closed non-coding RNA that plays emerging roles in tumorigenesis and aggressiveness. However, the functions and underlying mechanisms of circRNAs in regulating gastric cancer progression still remain elusive. We identify circ-hnRNPU, a circRNA derived from exons 5, 6, 7 and 8 of heterogeneous nuclear ribonucleoprotein U (hnRNPU), as a tumor suppressor of gastric cancer progression. To investigate the mechanisms underlying the functions of circ-hnRNPU, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human gastric cancer MKN-45 and AGS cells in response to stable over-expression of circ-hnRNPU. The results showed that stable over-expression of circ-hnRNPU led to altered expression of 112 human mRNAs, including 64 up-regulated and 48 down-regulated genes, in both MKN-45 and AGS cells. Furthermore, we validated the RNA-seq results by real-time RT-PCR with high identity. Overall, our results provided fundamental information about the transcriptomic changes in response to circ-hnRNPU over-expression in human gastric cancer cells, and these findings will help us understand the pathogenesis of cancer progression.

Integrated Profiling and Immunohistochemistry Analyses Link circ-BRIP1, circ-EPHB4 and Their Host Genes with Imatinib Resistance in Gastrointestinal Stromal Tumors

Project description:Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the digestive tract. The majority of GIST patients eventually develop resistance to imatinib therapy. To identify the responsible mechanisms, we investigated the differentially expressed mRNAs and circRNAs in imatinib-resistant GISTs using SBC ceRNA microarrays. We found that 107 mRNAs and 521 circRNAs were significantly differentially expressed between imatinib-naïve and imatinib-resistant GIST tissue samples. qRT-PCR analyses validated that circ-BRIP1, circ-EPHB4 and circ-RECQL4 and their host genes were upregulated in imatinib-resistant GISTs, and circ-BRIP1, circ-EPHB4, and RECQL4 were associated with imatinib resistance, tumor relapse and progression, and metastasis in GIST patients. The expression levels of circ-BRIP1, circ-EPHB4 and their host genes were also evaluated using TMAs with 150 human GISTs. The expression level of EPHB4 was significantly increased in high-grade GISTs in comparison to low-grade GISTs and correlated with imatinib resistance. Specifically, we first developed a method for high-throughput analysis of the expression of differentially expressed circRNAs by ISH-IHC in a set of FFPE-tissue microarrays in GIST. Our results also suggested a possible role for circ-BRIP1, circ-EPHB4, and their host genes in the progression of GISTs.

The mechanism of circ-ARAP2 regulation of tumor EMT and stem cell differentiation affecting proliferation, invasion and chemotherapy resistance of Esophageal Squamous Cell Carcinoma

Project description:Circular RNAs (circRNAs) belong to a novel class of noncoding RNA that gained more attention in human cancer pathogenesis. The circRNA roles in esophageal squamous cell carcinoma (ESCC) is unknown. Present investigation was to characterize new circRNAs regulating ESCC progression and explore the regulatory mechanisms in ESCC. In this study, circRNAs differentially expressed in ESCC and adjacent normal tissues were characterized via high-throughput sequencing. We then investigated the effects of the differentially expressed circRNA ARFGAP with RhoGAP domain, ankyrin repeat and PH domain 2 (circ-ARAP2) on tumor progression in vivo and in vitro. We used luciferase reporter assays to identify the relationships between circ-ARAP2, its target microRNA (miR)-761 and the cell cycle regulator Forkhead Box M1 (FOXM1). Expression profile analyses regarding human circRNAs in ESCC demonstrated that circ-ARAP2 was up-regulated significantly in ESCC tissues and cell lines. The circ-ARAP2 down-regulation suppressed ESCC proliferation, tumor growth and metastasis in vivo and in vitro. The data also suggested that miR-761 and FOXM1 were circ-ARAP2 downstream targets which were confirmed through luciferase reporter analysis. Overexpression of FOXM1 or inhibiting miR-761 slowed ESCC cell proliferation and invasion after silencing circ-ARAP2. circ-ARAP2 also influenced the endothelial-mesenchymal transition (EMT) and cancer stem cells differently by regulating miR-761/FOXM1. In one word, the results demonstrated that abnormal circ-ARAP2 expression promoted ESCC progression by regulating miR-761/FOXM1 axis-mediated stemness and EMT.

A peptide CORO1C-47aa encoded by circ-0000437 functions as a negative regulator in endometrium tumor angiogenesis

Project description:Circular RNAs (circRNA) are a novel class of widespread non-coding RNAs (ncRNAs) that regulate gene expression in mammals. Recent studies demonstrate that functional peptides can be encoded by short open reading frames (sORFs) in ncRNAs, including circRNAs. In this study, through deep RNA sequencing on human endometrial cancer (EC) samples and their paired adjacent normal tissues, we uncovered that the circRNA hsa-circ-0000437 is significantly reduced in EC compared to matched paracancerous tissue. The hsa-circ-0000437 contains a sORF encoding a functional peptide termed as CORO1C-47aa. Overexpression of CORO1C-47aa is capable of inhibiting angiogenesis at the initiation stage by suppressing endothelial cell proliferation, migration, and differentiation through competing with TACC3 to bind to ARNT and suppress VEGF. The anti-tumor effects of CORO1C-47aa on EC progression suggest that CORO1C-47aa has a potential value in anti-carcinoma therapies and deserves further investigation.

Circ-CAMTA1 regulated by Ca2+ influx inhibited pyruvate carboxylase activity and modulate T cell function in patients with systemic lupus erythematosus

Project description:The expression profiles of circRNAs in Jurkats cells, co-cultured with and without ionomycin, were analyzed by next-generation sequencing and validated using real-time polymerase chain reaction. The identified Ca2+ influx-regulated circRNAs were further examined in T cells from 42 patients with SLE and 23 healthy controls. The biological function of specific circRNAs was investigated using transfection and RNA pull-down assay. After validation, we confirmed that the expression levels of circ-ERCC4, circ-NFATC2, circ-MYH10, circ-CAMTA1, circ-ASH1L, circ-SOCS7, and circ-ASAP1 were consistently increased in Jurkat cells following Ca2+ influx. The expression levels of circ-CAMTA1, circ-ASH1L, and circ-ASAP1 were significantly lower in T cells from patients with SLE, with even lower levels observed in those with higher disease activity. Interferon (IFN)-α was found to suppress the expression of circ-CAMTA1. Circ-CAMTA1 bound to pyruvate carboxylase and inhibited its biologic activity. Overexpression of circ-CAMTA1, but not its linear form, significantly decreased extracellular glucose levels. Furthermore, increased expression of circ-CAMTA1, but not its linear form, enhanced IL-2 secretion and the protein expression of NFAT1.

Study on the mechanism of circ-PDE5A inhibiting the progression of esophageal squamous cell carcinoma

Project description:Objective: Esophageal squamous carcinoma (ESCC) is one of the most common gastrointestinal tumors, and the PI3K/AKT signaling pathway plays a key role in the development of ESCC. circRNAs have been reported to be involved in the regulation of PI3K/AKT signaling, but the underlying mechanisms are unclear. This study aimed to identify protein-coding circRNAs and investigate their function in ESCC. Design: Differential expression of circRNAs between ESCC tissues and adjacent normal tissues was identified using circRNA microarray analysis. A novel protein encoded by circ-PDE5A was identified by LC-MS/MS. Molecular biological methods were used to explore the biological functions and regulatory mechanisms of circ-PDE5A and its encoded PDE5A-500aa novel protein in ESCC. Construction of a nanoplatform for the coupling of circRNAs to investigate the therapeutic translation value of circ-PDE5A. Results: We found that circ-PDE5A expression was downregulated in ESCC cells and tissues, and its low expression was associated with later clinicopathological staging and poorer prognosis. Functionally, circ-PDE5A inhibited ESCC proliferation and metastasis in vitro and in vivo by encoding the novel PDE5A-500aa protein, which was identified as a key player in regulating PI3K/AKT signaling activation in ESCC. Mechanistically, the novel PDE5A-500aa protein binds directly to PIK3IP1 and promotes USP14-mediated deubiquitination of the k48-linked polyubiquitin chain at residue K198 of PIK3IP1, thereby attenuating PI3K/AKT pathway in ESCC. In addition, the circ-PDE5A plasmid-coupled reduction-responsive nanoplatform successfully inhibited ESCC growth and metastasis. Conclusions: circ-PDE5A represents an epigenetic mechanism regulating PI3K/ATK signaling and serves as a novel and promising therapeutic target and prognostic marker for ESCC.

circ-ZNF609 regulates G1-S progression in Rhabdomyosarcoma

Project description:Circular RNAs (circRNAs) represent a class of covalently closed RNAs, derived from a non-canonical splicing event, ubiquitously expressed among Eukaryotes and conserved among different species. We identified a circRNA (circ-ZNF609) involved in the regulation of human primary myoblast proliferation. Upon its depletion, the percentage of proliferating myoblasts was highly reduced. To deepen our knowledge about circ-ZNF609 role in cell cycle regulation, we studied its expression and function in Rhabdomyosarcoma (RMS), a pediatric skeletal muscle malignancy. We found that circ-ZNF609 is up-regulated in biopsies from both the two major RMS subtypes, the alveolar (ARMS) and the embryonal (ERMS), and we discovered that its knock-down blocks proliferation of an ERMS-derived cell line, while it has no effect on ARMS-derived cells. To understand the mechanism through which circ-ZNF609 affects cell proliferation we compared the different effects of circ-ZNF609 depletion in ERMS and ARMS and we identified genes and pathways on which the circRNA acts.
