(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) 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) Dickkopf 1 (DKK1), which is expressed at high mRNA levels by fibroblasts in the dermis of human skin on the palms and soles, inhibits the function and proliferation of melanocytes in the epidermis of those areas via the suppression of beta-catenin and microphthalmia-associated transcriptor factor (MITF). In this study, we report that treatment of keratinocytes with DKK1 increases their proliferation and decreases their uptake of melanin, and that treatment of reconstructed skin with DKK1 induces a thicker and less pigmented epidermis. more...

(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) The MYCN oncoprotein broadly binds promoters in a heterodimer with its partner protein MAX. MYCN also interacts with the nuclear exosome, a 3’-5’exoribonuclease complex, to facilitate progression through the S phase hinting at an RNA-centric function. Here we show that MYCN forms stable high molecular weight complexes with multiple RNA-binding proteins including the nuclear exosome. RNA-binding assays reveal that MYCN directly binds to thousands of predominantly intronic RNA sites via a short, highly conserved sequence motif termed MYCBoxI. more...

(Submitter supplied) To study differentially expressed genes in neuro-ectodermal cell lines MYCN amplification (NMA) is the most important prognostic factor in neuroblastoma (NBL) patients, however 70% of advanced stage NBL are non-NMA and lack known driving oncogenic events. Gene expression profiles (HU133plus2.0 arrays, Affymetrix) of 17 NBL and 5 peripheral neuro-ectodermal cell lines were used to identify potential subgroups of NBL cell lines with a distinct gene signature. more...

(Submitter supplied) MYCN is a master regulator controlling many processes necessary for tumor cell survival. Here, we unravel a microRNA network that causes tumor suppressive effects in MYCN-amplified neuroblastoma cells. In profiling studies, histone deacetylase (HDAC) inhibitor treatment most strongly induced miR-183. Enforced miR-183 expression triggered apoptosis, and inhibited anchorage-independent colony formation in vitro and xenograft growth in mice. more...
