Genome-wide occupancy of RORB in neuroblastoma cells.

ABSTRACT: Neuroblastoma (NB), a malignant embryonic tumor arising from primitive neural crest cells, accounts for more than 7% of malignancies and around 15% of cancer-related mortality in childhood. Better elucidating the mechanisms of tumorigenesis and aggressiveness is important for improving the therapeutic efficiencies of NB. To investigate the mechanisms underlying the tumor suppressive functions of RAR-related orphan receptor B (RORB), we employed the Illumina HiSeq X Ten as a discovery platform to analyze the genome-wide occupancy of RORB on target genes in human SK-N-BE(2) cells. The results showed that 1637 target genes were regulated by transcriptional regulator RORB, especially those involved in regulation of NF-κB signaling pathway. Furthermore, we validated the ChIP-seq results by real-time PCR with high identity. Overall, our results provided fundamental information about the genomic enrichment of RORB in human NB cells, and these findings will help us understand the pathogenesis of NB.

Transcriptomic analysis of neuroblastoma cells in response to RORB over-expression

Project description:Neuroblastoma, the most common extracranial solid malignancy in infants and young children, originates from aberrant neural crest cells and accounts for 10-15% of childhood cancer deaths. However, the underlying mechanisms regulating neuroblastoma progression remain to be determined. To investigate the mechanisms regulating tumorigenesis and aggressiveness, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human neuroblastoma SK-N-BE(2) cells in response to over-expression of RAR-related orphan receptor B (RORB). The results showed that 2027 and 1549 genes were respectively elevated or reduced in SK-N-BE(2) cells following RORB over-expression. 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 RORB over-expression in human neuroblastoma cells, and these findings will help us understand the pathogenesis of neuroblastoma progression.

Project description:Neuroblastoma (NB), a malignant embryonic tumor arising from primitive neural crest cells, accounts for more than 7% of malignancies and around 15% of cancer-related mortality in childhood. Better elucidating the mechanisms of tumorigenesis and aggressiveness is important for improving the therapeutic efficiencies of NB.

The results showed that stable over-expression of NHEG1 led to altered expression of 869 human mRNAs, including 499 up-regulated genes and 370 down-regulated genes. Then we found the possible roles of these differentially regulated mRNAs in selected pathways including cell cycle/proliferation, apoptosis, and cytokine/chemokine responses by Bioinformatic analysis.
