Project description:Genome-wide copy number variation profiles were analyzed in the patient-derived gliobastoma cell culture samples. For this purpose, gDNA was analyzed using the CytoScan® assay in combination with a one-color based labeling and hybridization protocol. Signals on the CytoScan® HD microarrays were detected using the Affymetrix GeneChip® 3000 Scanner.

Project description:Retinoblastoma is a childhood retinal tumor that initiates in response to biallelic RB1 inactivation. We show that post-mitotic human cone precursors are uniquely sensitive to the oncogenic effects of Rb depletion. Rb knockdown induced cone precursor proliferation in prospectively isolated populations. SNP-array analysis of two Rb/p130-depleted cone precursor cell lines, revealing no megabase-size loss of heterozygosity (LOH) or copy number alterations (CNAs). SNP-array analysis of one Rb/p130-depleted (tumor 1) or one Rb-depleted (tumor 2) cone precursor-derived tumors, revealing no megabase-size LOH or CNAs, consistent with the lack of DNA copy number alterations in some retinoblastomas. Thus, the cone precursor tumors resembled human retinoblastomas at the molecular cytogenetic level. High resolution SNP-array DNA copy number analyses were performed using CytoScan® HD (Affymetrix, 901835) according to the manufacturer's directions. Data were analyzed using Chromosome Analysis Suite 2.0 (Affymetrix). DNA was extracted from two Rb/p130 depleted cone precursor cell lines and two cryopreserved mouse retinoblastoma samples from eyes xenograted with Rb/p130 or Rb depleted cone precursors. Affymetrix SNP analysis on retinoblastoma cell lines Y79, RB176, and WERI were used as control. Normal human genome 19 was used as reference.

Project description:The Affymetrix CytoScan 750K Array chip contains 200000 SNP markers and 550000 CNV markers, distributed across the entire human genome at an average density of approximately 1 marker/4kb (not covering all loci of the entire chromosome genome). It is used to detect clinically significant chromosomal microdeletions/microduplications, chromosomal subtelomer deletion syndrome, and other abnormal chromosomal copy number variations (CNVs) as well as loss of heterozygosity (LOH). In a case study of Zhangzhou Municipal Hospital of Fujian Province, copy number variation detection was performed on a fetus with Silver-Russell syndrome using CytoScan 750K Array chip, and variations in the corresponding region were identified.

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.

Project description:The Affymetrix CytoScan HD array is a high resolution SNP platform for studying copy number variations in the human genome. It is widely being used in both clinical and research settings for identifying causative variants as well as interrogating the genome for benign variants. We employed this platform to investigate the risk factor CNVs in trios diagnosed with hemiplegic cerebral palsy. We genotyped 101 unrelated probands and their both parents and compared their genotypes to those of 9,611 population controls, in order to identify rare CNVs (<0.1% frequency) of at least 10 kb in size that might contribute to CP. We uncovered de novo CNVs and Decipher Syndromes in probands. We have identified additional potentially risk factor CNVs impacting the coding sequencing of genes involved in brain functions.
