Project description:Reference1: Ohira M, Oba S, Nakamura Y, Isogai E, Kaneko S, Nakagawa A, Hirata T, Kubo H, Goto T, Yamada S, Yoshida Y, Fuchioka M, Ishii S, Nakagawara A. Expression profiling of human primary Expression profiling using a tumor-specific cDNA microarray predicts the prognosis of intermediate risk neuroblastomas. Cancer Cell. 2005 Apr;7(4):337-50. To predict the prognosis of neuroblastoma patients and choose a better therapeutic protocol, we developed a cDNA microarray carrying 5340 genes obtained from primary neuroblastomas and examined 136 tumor samples. We made a probabilistic output statistical classifier that provided a high accuracy in prognosis prediction (89% at 5 years) and a highly reliable method to validate it. Kaplan-Meier analysis indicated that the patients in an intermediate group defined by existing markers are divided by microarray into two further groups with 5 year survivals for 36% and 89% of patients (p < 10(-4)), i.e., with unfavorably and favorably predicted neuroblastomas, respectively. According to these results, we developed a gene subset chip for a clinical tool, for which our classifier exhibited 88% prediction accuracy.

Project description:Migratory embryonal neuroblasts give rise to several tissues, including the sympathetic nervous system (SNS). Neuroblastomas are paediatric tumours of the peripheral SNS with a highly variable prognosis. We observed that high NOTCH3 expression in neuroblastomas correlated with a poor prognosis. Expression of a NOTCH3 transgene in neuroblastoma cells induced many motility genes and conferred a highly motile phenotype. Expression of these motility genes strongly correlated with NOTCH3 expression in neuroblastomas and many other tumours, suggesting a general role for NOTCH3 in regulation of these genes. Silencing of NOTCH3 or genes of the Notch-processing γ-secretase complex induced apoptosis in all neuroblastoma cell lines tested. These data suggest that NOTCH3 is a key-regulator of motility, and indispensable for survival of neuroblastoma cells.

Project description:RNA expression profiles of 105 primary neuroblastomas derived from customized 4 x 44k oligonucleotide microarrays (Agilent Technologies). These profiles are part of an integrative study combining genomewide epigenetic profiles with transcriptome data of the same neuroblastoma cohort. Tumors were derived from 40 low-risk, 9 intermediate-risk and 56 high-risk patients.

Project description:Neuroblastomas are characterized by recurrent segmental and/or numerical chromosomal abberations such as MYCN-amplification or 11q-deletion. To further elucidate recurrent chromosomal alterations, 16 neuroblastoma cell lines were investigated.

Project description:Integrated analysis of array-based comparative genome hybridization (aCGH) and gene expression profiling was conducted by using primary neuroblastomas. This submission corresponds the latter gene expression data. Keywords: other Thirty mass screening-detected and 40 sporadic neuroblastomas were analyzed by both aCGH and gene expression profiling. A UCSF BAC array carrying 2,464 clones was used for the former experiment. For the latter experiment, an in-house cDNA microarray, carrying 5,340 cDNAs obtained from the oligo-capping cDNA libraries generated from anonymous neuroblastoma tissues, were used. Preparation of RNA, hybridization, reading of spots, and statistical analyses were conducted as reported previously [Ohira M, et al. Cancer Cell 2005;7:337-50.]. This series corresponds expression profiles for 40 sporadic neuroblastomas.

Project description:To confirm the neuroblastomas (NB) identity of human neuroblastomas from mouse-human neural crest chimeric mice model (CHNBs) we characterized their gene expression profiles by RNA-Seq (CHNBs MYCN+ALKF1174L; n=8). For a global comparison of gene expression profiles of CHNBs with other NB models, we further collected RNA-seq data from patient derived xenografts of neuroblastoma (PDX NBs ; MYCNamp+ALKwt PDX; n=2, and MYCNamp+ALKF1174L PDX; n=3), neuroblastomas from genetically engineered mouse model (GEMM NBs; Th-MYCN+ALKF1174L; n=3), neuroblastoma established cell lines (n=2; Kelly, MYCNamp+ALKF1174L; SH-SY5Y, MYCNwt+ ALKF1174L), human pluripotent derived human neural crest cells (hNCCs; wt hNCCs; n=2, and MYCN+ALKF1174L hNCCs, with Dox; n=2) and from hNCC xenografts (MYCN+ALKF1174L; n=5).
