(Submitter supplied) Bromodomain inhibition comprises a promising therapeutic strategy in cancer, particularly for hematologic malignancies. To date, however, genomic biomarkers to direct clinical translation have been lacking. We conducted a cell-based screen of genetically-defined cancer cell lines using a prototypical inhibitor of BET bromodomains. Integration of genetic features with chemosensitivity data revealed a robust correlation between MYCN amplification and sensitivity to bromodomain inhibition. more...

(Submitter supplied) Polo-Like Kinase 1 (PLK1), a serine/threonine kinase involved in cell cycle regulation at the G2/M transition, is associated with high-risk neuroblastoma (NB) and unfavorable patient outcome. Recently, we and others demonstrated that PLK1 is a potential drug target in neuroblastoma and reported antitumoral actvity of the PLK1 inhibitor BI2536 in preclinical models of NB. We here analyzed the effects of the ATP-competitive PLK1 inhibitor GSK461364 on typical tumorigenic properties of preclinical in vitro and in vivo models of NB. more...

(Submitter supplied) Ewing sarcomas (ES) are highly malignant, osteolytic bone or soft tissue tumors, which are characterized by early metastasis into lung and bone. Genetically, ES are defined by balanced chromosomal EWS/ETS translocations, which give rise to chimeric proteins (EWS-ETS) that generate an oncogenic transcriptional program associated with altered epigenetic marks throughout the genome. By use of an inhibitor (JQ1) blocking BET bromodomain binding proteins (BRDs) we strikingly observed a strong down-regulation of the predominant EWS-ETS protein EWS/FLI1 in a dose dependent manner. more...

(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) Neuroblastomas are tumors of the developing peripheral sympathetic nervous system, which originates from the neural crest. Twenty percent of neuroblastomas show amplification of the MYCN oncogene, which correlates with poor prognosis. The MYCN transcription factor can activate and repress gene expression. To broaden our insight in the spectrum of genes down-regulated by MYCN, we generated gene expression profiles of the neuroblastoma cell lines SHEP-21N and SKNAS-NmycER, in which MYCN activity can be regulated. more...

(Submitter supplied) Neuroblastoma is a pediatric tumor of the sympathetic nervous system. MYCN (V-myc myelocytomatosis viral-related oncogene, neuroblastoma derived [avian]) is amplified in 20% of neuroblastomas, and these tumors carry a poor prognosis. However, tumors without MYCN amplification also may have a poor outcome. Here, we identified downstream targets of MYCN by shRNA-mediated silencing MYCN in neuroblastoma cells. more...

(Submitter supplied) Two genes have a synthetic lethal relationship when silencing or inhibition of one gene is only lethal in the context of a mutation or activation of the second gene. This situation offers an attractive therapeutic strategy, as inhibition of such a gene will only trigger cell death in tumor cells with an activated second oncogene but spare normal cells without activation of the second oncogene. Here we present evidence that CDK2 is synthetic lethal to neuroblastoma cells with MYCN amplification and overexpression. more...

(Submitter supplied) The CDK7 inhibitor THZ1 has been shown to suppress MYCN gene transcription but not cause significant cell death as a single agent. The tyrosine kinase inhibitors (TKIs) ponatinib and lapatinib were found to exert synergistic anti-cancer effects in combination with the CDK7 inhibitor THZ1, on MYCN amplified neuroblastoma cell lines.

(Submitter supplied) Promoter rearrangement of the telomerase reverse transcriptase (TERT) gene juxtaposes the coding sequence to strong enhancer elements, leading to TERT overexpression and poor prognosis. TERT associated oncogenic signaling in neuroblastoma remains unclear. Gene set enrichment analysis of RNA-seq data from 498 neuroblastoma patients revealed a coordinated activation of oncogenic signaling pathways and differentially overexpressed gene signature in a subgroup of MycN non-amplified neuroblastomas with TERT overexpression. more...

(Submitter supplied) mRNA profiles of thousands of human tumors are available, but methods to deduce oncogenic signaling networks from these data lag behind. It is especially challenging to identify main-regulatory routes, and to generalize conclusions obtained from experimental models. We designed the bioinformatic platform R2 in parallel with a wet-lab approach of neuroblastoma. Here we demonstrate how R2 facilitates an integrated analysis of our neuroblastoma data. more...
