Expression profiling of murine neuroblastoma in transgenic mice

ABSTRACT: Neuroblastoma is an embryonal tumor arising from the neural crest. It can be mimicked in mice by neural crest-specific overepxression of oncogenes such as MYCN or mutated ALK. Expression profiling of murine neuroblastoma driven by MYCN were compared to those driven by mutated ALK and to mouse normal adrenal tissue.

Transcriptional profiles of transgenic ALK^F1174L/MYCN vs. MYCN tumors

Project description:The ALK^F1174L mutation is associated with intrinsic and acquired resistance to crizotinib and cosegregates with MYCN in neuroblastoma. In this study, we generated a mouse model overexpressing ALK^F1174L in the neural crest. Comapred to mice expressing ALK^F1174L or MYCN alone, combined expression of the two aberrations led to development of neuroblastoma with a shorter latency and higher penetrance. Here, we evaluated the transcriptional profiles of MYCN-driven neuroblastomas with or without the expression of ALK^F1174L to determine the pathogenic consequences of the ALK^F1174L/MYCN interaction in neuroblastoma. 10 mice were analysed in this study. Five ALK^F1174L/MYCN tumors were compared with five MYCN tumors. Total RNA was extracted, samples were labeled and processed using the Agilent Low Input Quick Amp two color Cy3(sample) and Cy5 (mouse reference) labeling kit and hybridized to Agilent SurePrint G3 Mouse Gene Expression arrays.

Expression data from neuroblastoma of TH-MYCN/KI RetM919T mice

Project description:The RET gene has been identified previously as a target of activated ALK at the mRNA level in both human neuroblastoma cell lines and primary tumors as well as in murine tumors driven by mutated Alk and MYCN. Moreover, it has been shown that tumor growth of murine TH-MYCN/KI Alkmut tumors was impaired upon Ret inhibition by the vandetanib inhibitor, suggesting RET as a therapeutic target in ALK mutated neuroblastoma. To further demonstrate the crucial role of RET in ALK mutated driven neuroblastoma oncogenesis, transgenic TH-MYCN mice were bred with KI RetM919T tumors. We document an oncogenic cooperation between activated Ret and MYCN overexpression in neuroblastoma formation. We used microarrays to analyze the global programme of gene expression of MYCN/RetM919T tumors and compare these profiles with profiles of MYCN/Alkmut tumors (GSE46583). Altogether, our data show that MYCN/RetM919T tumors present with expression profiles close to MYCN/Alkmut tumors.

Expression data from neuroblastoma of TH-MYCN/KI Alk mice

Project description: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. We selected several murine neuroblastoma tumors for RNA extraction and hybridization on Affymetrix microarrays. We generated three groups of tumors: 10 MYCN amplified tumors, 11 MYCN amplified/ALK F1174L tumors and 10 MYCN amplified/ALK R1275Q tumors.

Gene expression profiling of MYCN-driven neuroblastoma tumor development in the TH-MYCN mouse model.

Project description:Neuroblastoma is an embryonic tumor arising from immature sympathetic nervous system progenitor cells. MYCN and ALK are driver oncogenes both of which are specifically expressed during early neurogenesis. This is in line with the assumption that neuroblastoma arises through disruption of normal developmental processes. MYCN has a broad impact on the tumor phenotype; however, the details of the MYCN driven oncogenic program are far from clear. In order to gain further insight into the role of gene expression during neuroblastoma initiation and progression, we evaluated gene expression profiles of hyperplastic ganglia and tumors isolated from MYCN transgenic mice.

Human embryonic stem cell-derived neural crest model for neuroblastoma

Project description:Neuroblastoma is a common childhood malignant tumor of neural crest origin with remarkable heterogeneity in outcomes. Amplification of the oncogene MYCN is strongly associated with highly malignant behaviour and poor prognosis. Here, we used human ESC-derived neural crest model to recapitulate the initiation of MYCN-driven neuroblastoma and to identify MYCN downstream effectors. Our results show that induced deregulation of MYCN in human neural crest progenitor cells is sufficient to induce tumors that recapitulate the pathological and molecular features of human MYCN-amplified neuroblastoma(MNA-NB). By using this platform, we are able to identify a group of 28 genes that are associated with MYCN expression level only in MNA-NB.

RNA-seq of TH-MYCN driven neuroblastoma mice +/- ALK F1178S mutation and +/- ALKAL2 overexpression

Project description:ALK is a tyrosine kinase receptor and oncogene in neuroblastoma (NB). The receptor is activated by the ALKAL2 ligand, but it is unknown whether missregulation of this ligand may play a role in NB carcinogenesis. Here, a TH-MYCN driven neuroblastoma mice was created +/- ALK F1178S mutation and +/- ALKAL2 overexpression

The role of miRNAs in neuroblastoma tumor development

Project description:Neuroblastoma (NB) is an embryonic tumor arising from immature sympathetic nervous system progenitor cells. MYCN and ALK are driver oncogenes both of which are specifically expressed during early neurogenesis. This is in line with the assumption that NB arises through disruption of normal developmental processes. MYCN has a broad impact on the tumor phenotype; however, the details of the MYCN driven oncogenic program are far from clear. In recent studies we demonstrated that MYCN drives the expression of a defined set of miRNAs that tightly control the expression of several key MYCN target genes, including several components of the TGFÎ² signaling pathway. In order to gain further insight into the role of miRNAs in NB initiation and progression, we evaluated miRNA profiles of hyperplastic ganglia and tumors isolated from MYCN transgenic mice.

Expression profiling of murine MYCN-driven neuroblastomas from LSL-MYCN; Dbh-iCre mice.

Project description:Amplification of MYCN is the most prominent genetic marker of high-stage neuroblastoma, a childhood tumor originating from the neural crest. We generated a transgenic mouse with Cre-conditional induction of MYCN in dopamine beta hydroxylase expressing cells that develops murine neuroblastomas. The expression profiles of six tumors from adrenals and two tumors from superial cervical gangliae were compared to three non-malignant adrenals from wildtype mice. These profiles of adrenals have been previously described (Molenaar et al., Nature Genetics 2012). Wild type samples are accessible at the AMC webpage: http://hgserver1.amc.nl/cgi-bin/r2/main.cgi, and accessible for registered users.
