Title Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of circular RNA derived from CUX1 gene (circ-CUX1)
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Summary 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 neuroblastoma progression still remain elusive. We identify one circRNA derived from CUX1 (circ-CUX1) as a novel driver of neuroblastoma progression. To investigate the mechanisms underlying the oncogenic functions of circ-CUX1, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human neuroblastoma IMR32 cells in response to stable over-expression of circ-CUX1. The results showed that stable over-expression of circ-CUX1 led to altered expression of 1215 human mRNAs, including 781 up-regulated genes and 434 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-CUX1 over-expression in human tumor cells, and these findings will help us understand the pathogenesis of tumor progression.
 
Overall design Total RNA of cells stably transfected with empty vector or circ-CUX1 was extracted using the TRIzol® reagent according to the manufacturer's instructions. RNA concentration was measured using a Qubit® RNA Assay Kit with a Qubit® 2.0 Fluorometer (Life Technologies, Inc.), and integrity was assessed using the RNA Nano 6000 Assay Kit with a Bioanalyzer 2100 system (Agilent Technologies, CA). Library preparation and transcriptome sequencing on an Illumina HiSeq X Ten platform were performed by Novogene Bioinformatics Technology Co., Ltd. (Beijing, China), and 100 bp paired-end reads were generated. HTSeq v0.6.0 was used to count the reads numbers mapped to each gene.
