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

ABSTRACT: 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 profiling of murine neuroblastoma in transgenic mice

Project description: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.

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.

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.

RNA-seq of neuroblastoma mice models after treatment with the ATR inhibitor BAY 1895344

Project description:To understand the in vivo transcriptomic response to ATR inhibition, RNA-Seq was performed after treatment of 2 previously developed neuroblastoma mouse models (Alk-F1178S;Th-MYCN and Rosa26_Alkal2;Th-MYCN; see Borenas et al., EMBO J, 2021) with the ATR inhibitor BAY 1895344.

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

ALK upregulates POSTN and WNT signaling to drive neuroblastoma

Project description:The goal of this study is to identify the mechanism for how ALK promotes tumorigenesis in neuroblastoma. We developed a human stem cell model of neuroblastoma and generated isogenic tumors using MYCN and MYCN/ALK. RNAseq analysis of both tumors revealed an enrichment in focal adhesion signaling and allowed us to find POSTN as a key mediator of ALK-mediated tumor growth.

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.
