Representing a novel type of endogenous noncoding RNAs, circular RNAs (circRNAs) have recently gained much attention for their involvement in multiple biological processes. CircRNAs are ubiquitously expressed in eukaryotic cells and modulate gene expression by acting as sponges of microRNAs (miRNAs) or other proteins, such as RNA-binding proteins (RBPs). Due to their unique structure, circRNAs are more stable than linear RNAs. Expression profiles of circRNAs are associated with clinicopathological characteristics of colorectal cancer patients, such as differentiation, TNM classification and distant metastasis...

AIM: We aimed to identify circular RNAs (circRNAs) associated with breast cancer chemoresistance. MATERIALS & METHODS: CircRNA microarray expression profiles were obtained from Adriamycin (ADM) resistant MCF-7 breast cancer cells (MCF-7/ADM) and parental MCF-7 cells and were validated using quantitative real-time reverse transcription PCR. The expression data were analyzed bioinformatically. RESULTS: We detected 3093 circRNAs and identified 18 circRNAs that are differentially expressed between MCF-7/ADM and MCF-7 cells; after validating by quantitative real-time reverse transcription PCR, we predicted the possible miRNAs and potential target genes of the seven upregulated circRNAs using TargetScan and miRanda...

Hundreds of circular RNAs (circRNAs) are highly abundant in mammalian brain, with oftentimes conserved expression. Here, we show that the circRNA Cdr1as is massively bound by miR-7 and miR-671 in the human and mouse brain. When the Cdr1as locus was removed from the mouse genome, knockout animals displayed impaired sensorimotor gating, a deficit in the ability to filter out unnecessary information associated with neuropsychiatric disorders. Electrophysiological recordings revealed dysfunctional synaptic transmission...

In recent years, some studies have been made on the effects of circular RNA (circRNA) in osteoarthritis (OA) and so on; however, its mechanisms remain to be further explored. Studies have shown that tumor necrosis factor-alpha can inhibit hsa_circ_0045714 expression in chondrocytes so as to upregulate miR-193b expression. Dual-luciferase reporter assay showed that insulin-like growth factor 1 receptor (IGF1R) is a key target gene of miR-193b. Hsa_circ_0045714 over-expression does not influence miR-193b expression, but can inhibit its transcriptional activity, thereby upregulating IGF1R expression...

Increasing evidences suggest that circular RNAs (circRNAs) exert crucial functions in regulating gene expression. In this study, we perform RNA-seq and identify 6,154 distinct circRNAs from human bladder cancer and normal bladder tissues. We find that hundreds of circRNAs are significantly dysregulated in human bladder cancer tissues. We further show that circHIPK3, also named bladder cancer-related circular RNA-2 (BCRC-2), is significantly down-regulated in bladder cancer tissues and cell lines, and negatively correlates with bladder cancer grade, invasion as well as lymph node metastasis, respectively...

Interconversions between epithelial and mesenchymal states, often referred to as epithelial mesenchymal transition (EMT) and its reverse MET, play important roles in embryonic development and are recapitulated in various adult pathologies including cancer progression. These conversions are regulated by complex transcriptional and post-transcriptional mechanisms including programs of alternative splicing which are orchestrated by specific splicing factors. This review will focus on the latest developments in our understanding of the splicing factors regulating epithelial mesenchymal plasticity associated with cancer progression and the induction of pluripotency, including potential roles for circular RNAs (circRNAs) which have been recently implicated in these processes...

Circular RNAs (circRNAs) represent a newly identified class of non‑coding RNA molecules, which interfere with gene transcription by adsorbing microRNAs (miRNAs). CircRNAs serve important roles in disease development and have the potential to serve as a novel class of biomarkers for clinical diagnosis. However, the role of circRNAs in the occurrence and development of gastric cancer (GC) remains unclear. In the present study, the expression profiles of circRNAs were compared between GC and adjacent normal tissues using a circRNA microarray, following which quantitative polymerase chain reaction (qPCR) was used to confirm the results of the circRNA microarray...

Generated by Quaking (QKI), circular RNAs (circRNAs) are newly recognised non-coding RNA (ncRNA) members characterised by tissue specificity, increased stability and enrichment within exosomes. Studies have shown that ionizing radiation (IR) can influence ncRNA transcription. However, it is unknown whether circRNAs or indeed QKI are regulated by IR. Microarray circRNA profiling and next generation sequencing revealed that circRNA expression was altered by low and medium dose exposure sourced predominantly from genes influencing the p53 pathway...

Circular RNAs (circRNAs) are a class of long, non-coding RNAs molecules that shape a covalently closed continuous loop which have no 5'-3' polarity and contain no polyA tail. CircRNAs also possess relatively jarless framework and are highly tissue-specific expressed in the eukaryotic transcriptome. Emerging evidences have discovered that thousands of endogenous circRNAs are present in mammalian cells and they mediate gene expression at the transcriptional or post-transcriptional level by binding to microRNAs or other molecules and then inhibit their function...
