RNA Sequencing and Bioinformatics Analysis of CircRNAs in Asphyxial Newborns with Acute Kidney Injury

ABSTRACT: Objective: As one kind of novel non-coding RNA with high stability and conservatism, circular RNAs (circRNAs) are involved in different biological processes. Although growing evidence has supported the important role of circRNAs in renal diseases, the specific mechanism still remains unknown in neonatal acute kidney injury (AKI). Methods: High throughput sequencing analysis was applied to investigate the expression patterns of circRNAs in the comparison between hypoxia induced AKI neonates and controls. Then, bioinformatics analysis was conducted to predict the function of differentially expressed circRNAs and construct the network of circRNA-miRNA interaction. Results: (1) We identified 296 differentially expressed circRNAs (circRNAs with Fold change > 2 and P value < 0.05). Of them, 184 circRNAs were markedly up-regulated and 112 were significantly down-regulated in the AKI group. (2) Bioinformatics analysis indicated that the parental genes of the differentially expressed circRNAs were predominantly implicated in the cell and cell part, cellular process and cancer pathways. Conclusion: This study could contribute to future research of circRNAs in the pathogenesis of neonatal AKI and facilitate the identification of novel therapeutic targets of circRNAs.

Next Generation Sequencing Analysis of CircRNAs/linear RNA in Isolated Renal Proximal Tubule tissues from Acute kidney injury mice

Project description:The goal of this study was to find the differentially expressed circRNAs/linear RNA in AKI mice model compared to normal mice. We established cisplatin-induced AKI mice models and then extracted RNAs from isolated renal tubular tissues for Next Generation Sequencing(NGS) at different time points during early stage of AKI. CircRNA library was constructed by NEB Next®Ultra™ small RNA Sample Library Prep Kit for Illumina®. NGS was performed by using Illumina HiSeq 2500 Genome Sequencers.The original image data file was transformed into Raw Data by Base Calling. Clean Data was obtained by removing reads that containing joints and more than 5% N (undetermined base information). Mapped Reads were obtained by sequence alignment between Clean Reads and reference genome sequenced using BWA software package. CIRI software was used to predict circRNAs. Finally, we identified 2162 circRNAs and our study represents the first detailed analysis of AKI mice circRNA transcriptomes, which provide a framework for investigations of circRNAs expression profiles in AKI

Circular RNA cFUT8 acts as an epithelialâmesenchymal transition trigger in liver cancer.

Project description:Using the highly sensitive cricRNA array, we screened 13617 circRNAs abundant in the human liver cancer and Adjacent normal liver tissues, and the function of differentially expressed circRANs were analyzed by bioinformatics. The results revealed that cFUT8 controls epithelialâmesenchymal transition in liver cancer by cFUT8/miR-548c-3p/FUT8 axis. In this study, three cases of liver cancer samples were used to acquire the circRNA expression profiling, and qRT-PCR was employed to confirm the results of circRNA microarrays. The functions of the differentially expressed circRNA were analyzed by bioinformatics methods. Finally, through in vivo and ex vivo experimentsï¼the âcFUT8/miR-548c-3p/FUT8 axisâ was found to control epithelialâmesenchymal transition in liver cancer

circRNA, lncRNA and mRNA profiles of umbilical cord blood exosomes from preterm newborns showing bronchopulmonary

Project description:Purpose: The purpose of this study was to detect the expression profiles of circRNAs, lncRNAs and mRNAs in umbilical cord blood (UCB) exosomes from BPD infants. Methods:Microarray analysis was performed to compare the RNA profiles of UCB-derived exosomes from preterm newborn with and without BPD. Then, circRNA/lncRNA-miRNA-mRNA co-expression networks were built to determine their associations with BPD.Results:A total of 317 circRNAs, 104 lncRNAs, 135 mRNAs showed significant differential expression in UCB-derived exosomes from BPD preterm infants compared with the NBPD group. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were conducted for examining differentially expressed exosomal circRNAs, lncRNAs and mRNAs. Our results showed the GO terms and KEGG pathways mostly involving differentially expressed exosomal RNAs were closely associated with endothelial or epithelial cell development. In addition, two networks were identified, including circRNA-circ_0086018/miR-762/MEN1 and lncRNA-BASP1-AS1/miR-20a-5p/DNAJC22 networks, which may take part in BPD.

Expression profile and potential function of circRNAs in peripheral blood mononuclear cells from patients with primary gout

Project description:To determine the expression profile and clinical significance of circular RNAs (circRNAs) in peripheral blood mononuclear cells (PBMCs) of patients with primary gout and healthy control subjects. Human circRNA microarrays were used to identify the differentially expressed circRNAs in primary gout (Gout, n = 5) and healthy subjects (HC, n = 3). Bioinformatics analyses were performed to predict the roles of differently expressed circRNAs. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the results in 90 gout patients, and 60 healthy control subjects (HC). Microarray analysis indicated that 238 circRNAs were up-regulated and 41 circRNAs were down-regulated in the Gout group (Fold change>1.5, p-value<0.05). Bioinformatics analysis showed that differentially expressed circRNAs were involved in the pathogenesis of gout through a variety of different pathways. Significant association was observed between these circRNAs and lipid metabolism indicators. Our results provide novel insight into the mechanisms of primary gout, and reveal that hsa_circRNA_103657 could effectively discriminate the gout group and the healthy control groups.
