Project description:Single-color gene expression profiles from IMR-32 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. To gain insights into the molecular processes occurring upon TFAP2B re-expression, we performed gene expression measurements in TFAP2B and GFP expressing transgenic IMR-32 neuroblastoma cell lines at d2 and d7 of transgene induction. Single-color gene expression profiles from IMR-32 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. Total RNA of TFAP2B- and GFP-expressing IMR-32 cells was isolated at day 2 and day 7 using Trizol.
Project description:To reveal the genome-wide targets of SWI/SNF complexes in neuroblastoma cells, we performed ATAC-seq in IMR-32 cells with or without SMARCA4 inactivation. To identify changes in DNA accessibility following SMARCA4 inactivation, we used either the small-molecule catalytic inhibitor BRM014, auxin-induced degradation of IMR-32 cells engineered with SMARCA4 tagged to the minimal auxin-induced degron (SMARCA4-mAID), or the corresponding vehicle controls. Analysis of these locations reveal that SMARCA4-dependent sites are located at enhancers used by the neuroblastoma core regulatory circuitry.

Project description:The human neuroblastoma cell lines SH-SY5Y and IMR-32 can be differentiated into neuron-like phenotypes through treatment with all-trans retinoic acid (ATRA). After differentiation, these cell lines are extensively utilized as in vitro models to study various aspects of neuronal cell biology. However, temporal and quantitative profiling of the proteome and phosphoproteome of SH-SY5Y and IMR-32 cells throughout ATRA-induced differentiation has been limited. Here, we performed relative quantification of the proteomes of SH-SY5Y and IMR-32 cells at multiple time points during ATRA-induced differentiation. The data presented serve as a valuable resource for investigating temporal protein and phosphoprotein abundance changes in SH-SY5Y and IMR-32 cells during ATRA-induced differentiation.

Project description:To assess the genome-wide effects of SWI/SNF activity in MYCN-amplified neuroblastoma cells, we performed ChIP-seq in IMR-32 cells treated with either DMSO or the SWI/SNF inhibitor BRM014. Pronounced loss of chromatin occupancy was observed for members of the neuroblastoma core regulatory circuitry within 1 hour.
Project description:To reveal the genome-wide targets of SWI/SNF complexes in neuroblastoma cells, we performed ChIP-seq of SMARCA4 (BRG1) in IMR-32, KELLY, and SK-N-DZ cells. We used these libraries to examine chromatin occupancy profiling. Analysis of locations reveal that SMARCA4 targets directly regulate sites regulated by the neuroblastoma core regulatory circuitry.
Project description:IMR-32 cells were subjected to lentiviral YRNA infection or nELAVL RNAi and/or UV stress followed by RNAseq analysis to monitor RNA level changes RNA from IMR-32 cells was Trizol extracted, Ribominus selected and submitted for high-throughput sequencing.
