Project description:In order to find out circular RNAs profiles in human bladder cancer tissues and normal bladder tissues, we characterized circuclar RNA transcripts by performing RNA-Seq on ribosomal RNA-depleted total RNA from three pairs of human bladder cancer tissues and paired normal bladder tissues.A computational pipeline based on the anchor alignment of unmapped reads was used to identify circular RNAs. Collectively, we identified16,535 distict circular RNAs, most of them origined from exons (88.96%), others from introns, linc RNA, intergenic region, 3’UTR and 5’UTR. Among all these circRNAs, 571 circRNAs were differentially expressed between bladder cancer tissues and normal bladder tissues, and 524 circRNAs were downregulated in bladder cancer tissues (91.2%), others were upreguluated. These significantly differential expressed circular RNA might have regulatory function in bladder cancer, and worth to be further explored.

Project description:Objective: Bladder outlet obstruction (BOO) is a common urologic disease associated with poorly understood molecular mechanisms. This study aimed to investigate the possible involvements of circRNAs (circular RNAs) and circRNA-encoded proteins in BOO development. Methods: The rat BOO model was established by the partial bladder outlet obstruction surgery. Differential expression of circRNA and protein profiles were characterized by deep RNA sequencing and iTRAQ quantitative proteomics respectively. Novel proteins encoded by circRNAs were predicted through ORF (open reading frame) selection using the GETORF software and verified by the mass spectrometry in proteomics, combined with the validation of their expressional alterations by quantitative RT-PCR. Results: Totally 3051 circRNAs were differentially expressed in bladder tissues of rat BOO model with widespread genomic distributions, including 1414 up-regulated and 1637 down-regulated circRNAs. Our following quantitative proteomics revealed significant changes of 85 proteins in rat BOO model, which were enriched in multiple biological processes and signaling pathways such as the PPAR and Wnt pathways. Among them, 21 differentially expressed proteins were predicted to be encoded by circRNAs and showed consistent circRNA and protein levels in rat BOO model. The expression of five protein-encoding circRNA were further validated by quantitative RT-PCR and mass spectrometry. Conclusion: The circRNA and protein profiles were substantially altered in rat BOO model, with great expressional changes of circRNA-encoded novel proteins.

Project description:To explore circular RNA (circRNA) expression profiling and their biological functions in bladder cancer, we surveyed the circRNA expression signature of 4 pairs of matched bladder cancer and para-cancer tissues from clinical patients using microarray. Hundreds of significantly changed circRNAs were identified. Our findings provide a novel perspective on transcriptional group and lay the foundation for future research of potential roles of circRNAs in bladder carcinoma.

Project description:Circular RNAs (circRNAs) have been increasingly indicated to be important participants in the development and progression of various malignant tumors. Our previous studies found that hundreds of circRNAs were aberrantly expressed in bladder cancer (BC) by high-throughput sequencing and we have confirmed that the downregulated circRNAs circHIPK3, BCRC3 and circNR3C1 played inhibitory roles in BC progression. However, the role of these upregulated circRNAs remain to be clarified. In this study, we analyzed circRNA high-throughout sequencing from human tissues and focused on the upregulated circRNAs and identified a novel circular RNA, hsa_circ_0001361 (also named bladder cancer upregulated circRNA-1, BCUC-1), as a new candidate circRNA derived from FNDC3B gene. The expression levels of circRNA and miRNAs in BC tissues and cells were detected by qRT-PCR. Transwell migration, Matrigel invasion, CCK-8, EdU, cell cycle and in vivo tumor metastasis assays were preformed to evaluate the effects of circ0001361 on BC cells. Transcriptome analysis was performed to find the potential genes that could be regulated by BCUC-1. Luciferase reporter, RNA pull-down and fluorescence in situ hybridization (FISH) assays were applied to verify the interaction between BCUC-1 and miR-491-5p.

Project description:In this study, we aimed to seek out abnormal noncoding RNAs (lncRNAs and circRNAs) involved in the development of bladder cancer through RNA-seq analysis. Transcriptome analysis of five pairs of bladder cancer tumor tissues and matched adjacent non-tumor tissues was completed in this project. A total of 68.18Gb clean data (sequencing data after quality control) was obtained. In conclusion, high-throughput sequencing analysis provided a distinctive landscape for the expression of noncoding RNAs and screened a series of significantly differently expressed lncRNAs and circRNAs, such as lncRNA LNPPS (ENST00000622374) and circSLC38A1. Further studies will focus on the potential function and intrinsic regulatory mechanisms of these significantly differently expressed lncRNAs and circRNAs in the development of bladder cancer.

Project description:Circular RNAs (circRNAs) have been increasingly indicated to be important participants in the development and progression of various malignant tumors. In this study, we re-analyzed circRNA high-throughout sequencing from human bladder cancer tissues and paired adjacent normal tissues. Then, we discover that a circRNA hsa_circ_0000591, named as circMGA, is significantly downregulated in bladder cancer. FISH assay has been proved that hsa_circ_0008399 mainly located in cytoplasm. Transcriptome analysis was performed to find the potential genes that could be regulated by circMGA.

Project description:To further explore the differential expression profile of circRNA in human bladder cancer, we have employed circRNA microarray expression profiling as a discovery platform to identify potential differential expression profile of circRNA between human bladder cancer cell (UM-UC-3 cell) and urothelial immortalized cell (SV-HUC-1 cell). Results showed a large number of differentially expressed circRNAs. In this study, we screened the eight circRNAs that were most significantly downregulated in the circRNA differential expression profile of bladder cancer cells, designed primers across the splice site, and detected them using qPCR. We found that hsa_circ_0047253 (circLAMA3) was most significantly decreased in the bladder cancer cells, then its biological function and action mechanism have been further explored in this study.
