Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of GATA2 antisense RNA 1 (GATA2-AS1)

ABSTRACT: Long noncoding RNAs (lncRNAs), one type of endogenous RNA longer than 200 nucleotides, play emerging roles in tumorigenesis and aggressiveness. However, the functions and underlying mechanisms of lncRNAs in regulating neuroblastoma progression still remain elusive. We identify GATA2 antisense RNA 1 (GATA2-AS1), a lncRNA derived from GATA binding protein 2 (GATA2), as a novel suppressor of neuroblastoma progression. To investigate the mechanisms underlying the oncogenic functions of GATA2-AS1, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human neuroblastoma BE(2)-C cells in response to stable over-expression of GATA2-AS1. The results showed that stable over-expression of GATA2-AS1 led to altered expression of 1933 human mRNAs, including 857 up-regulated genes and 1076 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 GATA2-AS1 over-expression in human tumor cells, and these findings will help us understand the pathogenesis of tumor progression.

Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of long noncoding RNA derived from HNF4A gene (HNF4A-AS1)

Project description:Long noncoding RNAs (lncRNAs), one type of endogenous RNA longer than 200 nucleotides, play emerging roles in tumorigenesis and aggressiveness. However, the functions and underlying mechanisms of lncRNAs in regulating neuroblastoma progression still remain elusive. We identify HNF4A antisense RNA 1 (HNF4A-AS1), a lncRNA derived from upstream region of hepatocyte nuclear factor 4 alpha (HNF4A), as a novel driver of neuroblastoma progression. To investigate the mechanisms underlying the oncogenic functions of HNF4A-AS1, we employed the Illumina HiSeq X Ten as a discovery platform to analyze the transcriptome profiling changes of human neuroblastoma SH-SY5Y cells in response to stable over-expression of HNF4A-AS1. The results showed that stable over-expression of HNF4A-AS1 led to altered expression of 4296 human mRNAs, including 2169 up-regulated genes and 2127 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 HNF4A-AS1 over-expression in human tumor cells, and these findings will help us understand the pathogenesis of tumor progression.

Identifying target genes for the long noncoding RNA, GATA2-AS1

Project description:We have identified a set of endothelial-enriched long noncoding RNAs (lncRNAs) in another experiment. In this experiment, we aim to identify genes that are regulated by the GATA2-AS1 lncRNA. We have depleted GATA2-AS1 using two distinct siRNA in human umbilical vein endothelial cells (HUVEC)

Long Noncoding RNA HNF1A-AS1 Regulates Proliferation and Migration in Esophageal Adenocarcinoma Cells

Project description:Objectives: Long non-coding RNAs (lncRNAs) have been shown to play important roles in the development and progression of cancer. However, functional lncRNAs and their downstream mechanisms are largely unknown in the molecular pathogenesis of esophageal adenocarcinoma (EAC) and its progression. Design: lncRNAs that are abnormally upregulated in EACs were identified by RNA-seq analysis, followed by quantitative RT-PCR (qRTPCR) validation using tissues from 31 EAC patients. Cell biological assays in combination with siRNA-mediated knockdown were performed in order to probe the functional relevance of these lncRNAs. Results: We discovered that a lncRNA, HNF1A-AS1, is markedly upregulated in human primary EACs relative to their corresponding normal esophageal tissues (mean fold change 7.2, p<0.01). We further discovered that HNF1A-AS1 knockdown significantly inhibited cell proliferation and anchorage independent growth, suppressed S-phase entry, and inhibited cell migration and invasion in multiple in vitro EAC models (p<0.05). A gene ontological analysis revealed that HNF1A-AS1 knockdown preferentially affected genes that are linked to assembly of chromatin and the nucleosome, a mechanism essential to cell cycle progression. The well-known cancer-related lncRNA, H19, was the gene most markedly inhibited by HNF1A-AS1 knockdown. Consistent to this finding, there was a significant positive correlation between HNF1A-AS1 and H19 expression in primary EACs (p<0.01). In order to identify novel oncogenic lncRNAs in esophageal adenocarcinogenesis, we carried out RNA-seq of a matched NE-BE-EAC tissue pair

Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of myeloid zinc finger 1 antisense RNA 1 (MZF1-AS1)

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. Through mining of public datasets, we identified myeloid zinc finger 1 antisense RNA 1 (MZF1-AS1) as a novel lncRNA associated with the progression of NB. To investigate the mechanisms underlying the oncogenic functions of MZF1-AS1, 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 MZF1-AS1. The results showed that stable over-expression of MZF1-AS1 led to altered expression of 2920 human mRNAs, including 1476 up-regulated genes and 1444 down-regulated genes. Then we found the possible roles of these differentially regulated mRNAs in selected pathways including proline synthesis, 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 MZF1-AS1 over-expression in human NB cells, and these findings will help us understand the pathogenesis of NB.

Transcriptomic analysis of neuroblastoma cells in response to stable over-expression of FOXD3 antisense RNA 1 (FOXD3-AS1)

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. Through mining of publically available microarray datasets, we discovered a novel 963-bp lncRNA, named FOXD3 antisense RNA 1 (FOXD3-AS1), as an independent prognostic marker for favorable clinical outcome of NB patients. To investigate the mechanisms underlying the oncogenic functions of FOXD3-AS1, we employed the Illumina HiSeq PE125/PE150 as a discovery platform to analyze the transcriptome profiling changes of human BE(2)-C cells in response to stable over-expression of FOXD3-AS1. The results showed that stable over-expression of FOXD3-AS1 led to altered expression of 3191 human mRNAs, including 1542 up-regulated genes and 1650 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. 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 FOXD3-AS1 over-expression in human NB cells, and these findings will help us understand the pathogenesis of NB.

GATA2 knockout study to investigated the role of GATA2 in human hematopoiesis

Project description:We generated homozygous GATA2 knockout human embryonic stem cells (GATA2-/- hESCs) and analyzed their blood differentiation potential. Paritcularly at the hemogenic endothelium (HE) stage and hematopoietic progenitor cell (HPC) stage. Our result revealed that GATA2-/- hESCs displayed attenuated generation of CD34+CD43+ HPCs, due to the impairment of endothelial to hematopoietic transition (EHT). However, GATA2-/- hESCs retained the potential to generate erythroblasts, macrophages, but never granulocytes. Through RNA-Seq and further rescue experiment, we further identified that SPI1 was responsible for the defect of GATA2-/- hESCs in generation of CD34+CD43+ HPCs and granulocytes.
