Project description:Both in situ synthesized long oligo arrays from Agilent Technologies and short oligo arrays from Affymetrix were used to meausre differential gene expression in RNA samples generated from (1) human neural stem cells treated with vehicle (EtOH, 0.01%) and tert-butylhydroquinone (tBHQ, 20µM) for 24h, and (2) neuroblastoma cells treated with vehicle (EtOH, 0.01%) and tert-butylhydroquinone (tBHQ, 10µM) for 24h. This SuperSeries is composed of the SubSeries listed below.

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.
Project description:Setdb1 is an epigenetic factors catalyzing modification of H3K9me3. Expression of its gene is localized to embryonic neural cells during vertebrate embryogenesis, suggesting its role in regulating neural stemness. The project is to identify the interaction partners of Setdb1, by which Setdb1 regulates neural stemness in neural stem cells.
Project description:We have showed that cancer cells (or tumorigenic cells) resemble neural stem/progenitor cells in regulatory network, tumorigenicity and differentiation potential. We have shown PRMT1 is a protein that is upreguated in and promotes vaious cancers. The expression of its gene is localized to embryonic neural cells during vertebrate embryogenesis. The project is to identify the interaction partners of PRMT1, by which PRMT1 regulates neural stemness in both cancer cells and neural stem cells.
