ABSTRACT: Differential gene expression in neuroblastoma cells after transfection with control siRNA, N-Myc siRNA-1, N-Myc siRNA-2, lncMycN siRNA-1 or lncMycN siRNA-2
Project description:Differential gene expression analysis of MYCN-amplified neuroblastoma cells after transfection with Control siRNA, LYAR siRNA-6 or LYAR siRNA-10
Project description:Transcriptional profiling of long noncoding RNAs in human neuroblastoma BE(2)-C after transfection with control siRNA or N-Myc siRNA We analysed which long nocoding RNAs were N-Myc targets.
Project description:N-Myc oncoprotein induces neuroblastoma by modulating gene transcription, and long noncoding RNAs exert biological effects by regulating gene expression. We analysed whether N-Myc and the long noncoding RNA lncMycN mediate the expression of common subsets of genes. Neuroblastoma Kelly cells were transfected with control siRNA, N-Myc siRNA-1, N-Myc siRNA-2, lncMycN siRNA-1 or lncMycN siRNA-2. RNA was extracted from the cells 48 hours after siRNA transfections, and subjected to differential gene expression studies with Affymetrix microarrays.
Project description:WDR5 is an important co-factor for N-Myc-regulated transcriptional activation and tumorigenesis We analysed whether WDR5 siRNAs modulate gene expression Neuroblastoma BE(2)-C cells were treated with control siRNA, WDR5 siRNA-1, and WDR5 siRNA-2 for 40 hours, and subjected to differential gene expression studies with Affymetrix microarrays.
Project description:WDR5 is an important co-factor for N-Myc-regulated transcriptional activation and tumorigenesis Using ChIP-Seq, We profiled key epigenetic marks H3K4 trimethylation in BE(2)-C neuroblastoma cells transfected with control siRNA or WDR5 siRNA-1 at N-Myc target gene promoters The results showed knockdown WDR5 significantly reduced H3K4me3 at 93.2% of N-Myc binding promoters, but only at 53.5% of N-Myc non-binding promoters.
