Project description:RECQL4 is a RecQ helicase implicated in DNA replication and genome maintenance. To investigate the effects of RECQL4 deficiency on genome instability induced by replication stress, genome-wide copy number alterations were analyzed using the Affymetrix CytoScan HD Array in WT and RECQL4-deficient U2OS cells with or without Cyclin E overexpression and/or ionizing radiation. Genome-wide copy number alterations were analyzed using the Affymetrix CytoScan HD Array. Raw CEL files are provided together with processed CYCHP files generated using Chromosome Analysis Suite (ChAS) version 4.5.
Project description:we used single-cell transcriptomics and genotyping arrays to characterize 17 neuroblastoma samples across different risk groups and genetic subsets.Fresh samples, obtained from surgical resections and core biopsies, were used for genome variation profiling. DNA extraction from neuroblastoma samples was performed using the DNeasy blood and tissue kit (Qiagen) according to the manufacturer’s protocol. DNA quality was assessed using the Tapestation platform (Agilent). SNP microarray analysis was performed using the Cytoscan HD Array (Affymetrix) and data was processed using the Chromosome Analysis Suite version 3.3.0.139.
