There is increasing evidence that circular RNAs (circRNAs) are involved in cancer development, but the regulation and function of human circRNAs remain largely unknown. In this study, we demonstrated that ZKSCAN1, a zinc finger family gene, is expressed in both linear and circular (circZKSCAN1) forms of RNA in human hepatocellular carcinoma (HCC) tissues and cell lines. Here, we analyzed a cohort of 102 patients and found that expression of both ZKSCAN1 mRNA and circZKSCAN1 was significantly lower (P<0.05) in the HCC samples compared with that in matched adjacent non-tumorous tissues by reverse transcription PCR (RT-PCR)...

Circular RNA (circRNA), a novel type of endogenous noncoding RNA (ncRNA), has become a research hotspot in recent years. CircRNAs are abundant and stably exist in creatures, and they are found with covalently closed loop structures in which they are quite different from linear RNAs. Nowadays, an increasing number of scientists have demonstrated that circRNAs may have played an essential role in the regulation of gene expression, especially acting as miRNA sponges, and have described the potential mechanisms of several circRNAs in diseases, hinting at their clinical therapeutic values...

Tumor recurrence is usually detected within one year after radical resection of stage III gastric cancer. This study aimed to establish the expression profile and determine potential circular RNAs (circRNAs) and predict the early recurrence of stage III gastric cancer. We identified 46 differently expressed circRNAs between cancer and adjacent normal tissues through circRNA microarray. We further screened eight indicators related to early recurrence. We subsequently divided the remaining cases into two cohorts...

Circular RNAs (circ RNAs) are a novel type of RNA that, unlike linear RNAs, form a covalently closed continuous loop and are highly represented in the eukaryotic transcriptome. They share a stable structure, high expression and often exhibit tissue/developmental-stage-specific expression. Emerging evidence indicates that circRNAs might play important roles in human disease, such as cancer, neurological disorders and atherosclerotic vascular disease risk. The huge potentials of circRNAs are recently being discovered from the laboratory to the clinic...

Circular RNAs (circRNAs) are a class of new found RNA molecules that have a special covalent loop structure without 5' cap and 3' tail. Researchers have found that circRNAs may be generated by intron-pairing-driven or lariat-driven circularization. They are cleared up via extracellular vesicles. They have some advantages such as stable, conservation, tissue specificity and so on. By severing as sponge of microRNAs, interacting with long non-coding RNAs, mRNA, or proteins, circRNAs regulate gene expression at transcriptional and post-transcriptional levels and contribute carcinogenesis...

CircRNAs are a novel type of RNAs. With the newly developed technology of next-generation sequencing (NGS), especially RNA-seq technology, over 30,000 circRNAs have already been found. Owing to their unique structure, they are more stable than linear RNAs. CircRNAs play important roles in the carcinogenesis of cancer. The expression of circRNAs is correlated with patients' clinical characteristics, and circRNAs play a vital role in many aspects of malignant phenotypes, including cell cycle, apoptosis, vascularization, and invasion; metastasis as a RNA sponge, binding to RBP; or translation...

Circular RNAs (circRNAs), a novel type of widespread and diverse endogenous non-coding RNAs (ncRNAs), which are different from the linear RNAs, form a covalently closed continuous loop without 5' or 3' polarities. The majority of circRNAs are abundant, conserved and stable across different species, and exhibit tissue/developmental-stage-specific characteristics. They are generated primarily through a type of alternative RNA splicing called "back-splicing," in which a downstream splice donor is joined to an upstream splice acceptor through splice skipping or direct splice...

Circular RNAs (CircRNAs) were first identified as a viroid and later found to also be an endogenous RNA splicing product in eukaryotes. In recent years, a series of RNA-sequencing analyses from a diverse range of eukaryotes have shed new light on these eukaryotic circRNAs, revealing dynamic expression patterns in various developmental stages and physiological conditions. In this review, we focus on circRNAs implicated in stress response pathways and explore potential mechanisms underlying their regulation. To date, circRNAs have been shown to act as scaffolds in the assembly of protein complexes, sequester proteins from native subcellular localization, activate transcription of parental genes, inhibit RNA-protein interactions, and function as regulators of microRNA activity...

Increasing evidence has demonstrated that androgen receptor (AR) plays important roles to promote the metastasis of clear cell renal cell carcinoma (ccRCC). The detailed mechanisms, especially how AR functions via altering the circular RNAs (circRNAs) remain unclear. Here we identified a new circRNA (named as circHIAT1) whose expression was lower in ccRCCs than adjacent normal tissues. Targeting AR could suppress ccRCC cell progression via increasing circHIAT1 expression. ChIP assay and luciferase assay demonstrated that AR suppressed circHIAT1 expression via regulating its host gene (HIAT1) expression at the transcriptional level...

Circular RNA (circRNA) was first reported over thirty years ago. With the development of high-throughput sequencing technologies, circRNA has been identified in an increasing number of species. However, few studies on circRNA have been reported in teleost fish. Accumulating transcriptome and phenotype data enable us to probe the biological functions of circRNA in fish species. Here, we report the identification of circRNAs from RNA sequencing (RNA-seq) data in large yellow croaker (Larimichthys crocea), a commercially important marine fish in China and East Asia...

BACKGROUND: Rat liver regeneration (LR) proceeds along a process of highly organized and ordered tissue growth in response to the loss or injury of liver tissue, during which many physiological processes may play important roles. The molecular mechanism of hepatocyte proliferation, energy metabolism and substance metabolism during rat LR had been elucidated. Further, the correlation of circular RNA (circRNA) abundance with proliferation has recently been clarified. However, the regulatory capacity of circRNA in rat LR remains a fascinating topic...

HuR influences gene expression programs and hence cellular phenotypes by binding to hundreds of coding and noncoding linear RNAs. However, whether HuR binds to circular RNAs (circRNAs) and impacts on their function is unknown. Here, we have identified en masse circRNAs binding HuR in human cervical carcinoma HeLa cells. One of the most prominent HuR target circRNAs was hsa_circ_0031288, renamed CircPABPN1 as it arises from the PABPN1 pre-mRNA. Further analyses revealed that HuR did not influence CircPABPN1 abundance; interestingly, however, high levels of CircPABPN1 suppressed HuR binding to PABPN1 mRNA...

Circular RNAs (circRNAs) are generated from diverse genomic locations and are a new player in the regulation of post-transcriptional gene expression. Recent studies have revealed that circRNAs play a crucial role in fine-tuning the level of microRNA (miRNA)-mediated regulation of gene expression by sequestering miRNAs. The interaction of circRNAs with disease-associated miRNAs suggests that circRNAs are important in the pathology of disease. However, the effects and roles of circRNAs in macrophage polarization have yet to be explored...

Circular RNAs (circRNAs), a class of noncoding RNAs generated from pre-mRNAs, participate in regulation of genes. The mechanism for regulation, however, is unknown. Here, to determine if, in human keratinocyte (HaCaT) cells, circular RNAs are involved in arsenite-induced acceleration of the cell cycle, a circRNA microarray was performed to analyze the variability of circRNAs in arsenite-treated HaCaT (As-HaCaT) cells and in arsenite-transformed (T-HaCaT) cells in comparison to control HaCaT cells. Among the circRNAs up-regulated in both As-HaCaT cells and T-HaCaT cells, hsa:circRNA_100284 (circ100284) had the greatest increase and was chosen for further research...
