(Submitter supplied) Cancer genomic studies that rely on analysis of diagnostic biopsies from primary tumors may not fully identify the molecular events associated with tumor progression. We hypothesized that characterizing the transcriptome during tumor progression in the TH-MYCN transgenic neuroblastoma model would identify oncogenic drivers that would be targetable therapeutically. We quantified expression of 32,381 murine genes in 9 hyperplastic ganglia harvested at 3 time points, and 4 tumor cohorts of progressively larger size (n=6 each group) in mice homozygous for the TH-MYCN transgene. more...

(Submitter supplied) The specific genes that influence neuroblastoma biology and are targeted by genomic alterations remain largely unknown. We quantified mRNA expression in a highly annotated series of 101 prospectively collected diagnostic neuroblastoma primary tumors and the expression profiles were determined using Affymetrix U95Av2 arrays. Comparisons between the sample groups allow the identification of genes with localized expression patterns. more...

(Submitter supplied) JoMa1 cells are pluripotent precursor cells, derived from the neural crest of mice transgenic for tamoxifen-inducible c-Myc. Following transfection with a cDNA encoding for MYCN, cells become immortlized even in the absence of tamoxifen.

(Submitter supplied) Neuroblastoma is an embryonic solid tumor of neural crest origin and accounts for 11% of all cancer-related deaths in children. Novel therapeutic strategies are therefore urgently required. MYCN oncogene amplification, which occurs in 20% of neuroblastomas, is a hallmark of high risk. Here we aimed to exploit molecular mechanisms that can be pharmacologically addressed with epigenetically modifying drugs, such as histone deacetylase (HDAC) inhibitors. more...

Analysis of BE(2)-C cells up to 72 hrs after transient transfection with construct pTRex-GRHL1. The three mammalian GRHL genes (GRHL1, -2, and -3) represent a highly conserved family of β-scaffold transcription factors. Results provide insight into the role of GRHL1 in neuroblastoma biology.

(Submitter supplied) Gene expression analysis was performed on 30 Neuroblastomas to identify genes whose transcription is significantly altered by recurrent chromosomal alterations. Genomic copy number losses and gains had been delineated in the tumours using FISH and SNP arrays. We have identified genes significantly altered by 7 recurrent alterations: 1p, 3p, 4p, 10q and 11q loss, 2p and 17q gain, and genes co-amplified and over-expressed as a result of MYCN amplification. more...

(Submitter supplied) Amplification of MYCN is the most prominent genetic marker of high-stage neuroblastoma, a childhood tumor originating from the neural crest. We generated a cell line (mNB-A1) from tumors developed in transgenic mouse and treated these cells with DMSO (n=6), the BRD4-inhibitor JQ1 (n=3) or the AURKA-inhibitor MLN8237 (n=3) for 24 h.

(Submitter supplied) Neuroblastoma is an embryonal neoplasm that remains of dramatic prognosis in its aggressive forms. Activating mutations of the ALK tyrosine kinase receptor have been identified in sporadic and familial cases of this cancer. We generated knock-in mice carrying the two most frequent Alk mutations observed in neuroblastoma patients. We used microarrays to detail the global programme of gene expression underlying the impact of ALK mutations on neuroblastoma formation in a MYCN amplified background.

(Submitter supplied) Amplification of the MYCN oncogene predicts treatment resistance in childhood neuroblastoma. Using a MYC target gene signature that predicts poor neuroblastoma prognosis we identified the histone chaperone, FAcilitates Chromatin Transcription (FACT), as a crucial mediator of the MYC signal and a therapeutic target in the disease. FACT and MYCN expression created a forward feedback loop in neuroblastoma cells that was essential for maintaining mutual high expression. more...
