Targeting EZH2 in MYCN-amplified Neuroblastoma [ChIP-seq]

Project description:Purpose: Identify new targets in MYCN-amplified Neuroblastoma Methods: ChIP-Seq experiments were performed on Kelly and LAN-1 neuroblastoma cells by using the following antibodies: anti-EZH2 (Cell Signaling 5246S); anti-H3K27me3 (Millipore 07-449); anti-H3K4me3 (Abcam ab8580). We evaluated the global EZH2 PRC2-dependence by identifiying direct genome-wide target genes for EZH2, H3K27me3 and H3K4me3. Results: We found that EZH2 serves a PRC2-dependent function in neuroblastoma, repressing neuronal differentiation. Moreover, EZH2-regulated genes were strongly repressed in MYCN-amplified and high-risk primary tumors. Conclusion: Our study supports testing EZH2 inhibitors in patients with MYCN-amplified neuroblastoma.

Genome-wide binding of MYCN protein in MYCN-amplified neuroblastoma cell lines

Project description:The MYCN locus is amplified in about half of high-risk neuroblastoma tumors. To identify genomic loci occupied by MYCN protein in the MYCN-amplified neuroblastoma cell lines NGP, Kelly and NB-1643, we performed chromatin immunoprecipitation coupled with Next-Generation Sequencing (ChIP-seq) using an anti-MYCN antibody.

Targeting EZH2 in MYCN-amplified Neuroblastoma [RNA-seq]

Project description:Purpose: Identify new targets in MYCN-amplified Neuroblastoma Methods: Kelly and LAN-1 neuroblastoma cells were treated in duplicate with 2 uM GSK126 (Excess Biosciences M60071-2) or DMSO for 2 or 5 days. RNA was extracted from cells with the RNeasy Kit (Qiagen). RNA libraries were prepared for sequencing using standard Illumina protocols. The pool of sixteen samples was sequenced on two lanes of an Illumina HiSeq, generating single end reads of 32-76 bp length. Transcript abundance (reads and FPKM scores) at GRCh37/hg19 RefSeq gene level was computed with the Feature Counts method implemented in the Bioconductor v3.2 Rsubread package (Liao et al., 2014). Results: Pharmacological suppression of EZH2 inhibited neuroblastoma growth. Transcriptomic analysis revealed that EZH2 serves a PRC2-dependent function in neuroblastoma, repressing neural differentiation. Moreover, EZH2-regulated genes were strongly repressed in MYCN-amplified and high risk primary tumors. These observations demonstrate that MYCN upregulates EZH2 leading to inactivation of a tumor suppressor program in neuroblastoma. Conclusion: Our study supports testing EZH2 inhibitors in patients with MYCN-amplified neuroblastoma.

Genome-wide mapping of MYCN binding in neuroblastoma cells

Project description:To identify the MYCN transcription factor binding sites across the genome, we performed chromatin immunoprecipitation followed by sequencing (ChIP-seq) using anti-MYCN and anti-IgG antibodies on a MYCN-amplified NB cell line, SK-N-BE(2)-C. Identification of MYCN binding in neuroblastoma cells.

Direct interaction of MYCN and p53 regulate transcriptional responses in neuroblastoma [ChIP-Seq]

Project description:The net transcriptome of a cancer cell is defined by relative levels of transcription factors, activators, suppressors and co-factors. These in turn are controlled by epigenetic, genetic and metabolic restraints. Here we used RNA-Seq, ChIP-qPCR, and ChIP-Seq to determine the impact of MYCN protein levels on p53 and MYCN mediated transcription in neuroblastoma, a p53 wild-type neural crest derived pediatric malignancy. Of note, about 25% of neuroblastoma is MYCN amplified and expresses 10-100 fold higher levels of MYCN protein than non-amplified tumors. We hypothesized that p53 functions would be globally altered by extreme MYCN levels and this could help to explain aggressive biology and poor long term survival which distinguishes MYCN-amplified neuroblastoma. In fact, we found that in the context of high MYCN levels, activation of p53 results in marked changes in transcription of specific p53 and MYCN target loci regulating apoptosis, DNA repair and cell cycle progression. Co-immunoprecipitation of endogenous and GST-fused proteins, as well as ChIP-qPCR confirms formation of p53/MYCN complexes and enrichment of both transcription factors at active loci. This p53/MYC interaction is independent of MYC/MAX complexes. Together, these data demonstrate MYCN to be a direct co-factor modulating p53 transcriptional output in MYCN amplified cancer.

ChIP-seq analysis of human neuroblastoma cell lines

Project description:The aim of the experiment is to identify genome wide binding sites for the transcription factor MYCN in MYCN non-amplified and MYCN amplified human neuroblastoma cell lines. Datasets are presented for the ChIP-seq analysis in the tetracycline inducible cell line SH-SY5Y-MYCN (SH-SY5Y/6TR(EU)/pTrex-Dest-30/MYCN), derivative of the parental cell line SH-SY5Y; for noninduced cells and for 24 and 48 hours of Tet induction. Analysis for patinet matched MYCN amplified cell lines SMS-KCN and SMS-KCNR is also included.
