Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of small peptide encoded by hepatocyte nuclear factor 4 alpha antisense RNA 1 (HNF4A-AS1)

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. We identified a small 51-amino acid peptide (sPEP1) encoded by hepatocyte nuclear factor 4 alpha antisense RNA 1 (HNF4A-AS1) in NB cells treated by serum deprivation. To investigate the mechanisms underlying the oncogenic functions of sPEP1, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human SH-SY5Y cells in response to stable over-expression of sPEP1. The results showed that stable over-expression of sPEP1 led to altered expression of 2543 human mRNAs, including 2457 up-regulated genes and 86 down-regulated genes. Then we found the possible roles of these differentially regulated mRNAs in selected pathways including stemness, senescence, invasion, and metastasis by Bioinformatic analysis. 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 sPEP1 over-expression in human NB cells, and these findings will help us understand the pathogenesis of NB.
