Multi-omic analysis in patient-derived organoids unravel the impact of chromosomal instability in colorectal cancer

ABSTRACT: Cytoscan high-density (HD) chromosomal microarray analysis was conducted on PDOs and matched fresh tissue to detect copy number alterations. Due to the deepness of Cytoscan HD which goes up to gene level, we aimed at assessing intra-patient copy number heterogeneity from different metastasis of the same patient. We detected relevant differences regarding copy number gains and losses. Interestingly, we detected heterogeneity also in terms of mosaicism, confirming heterogeneity in terms of subclonal copy number variations.

Genome-wide copy number analysis of patient-derived gliobastoma cell cultures

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.

Copy Number Variation data from non-trasformed human fibroblasts

Project description:The search for biomarkers to predict radiosensitivity is important not only to individualize radiotherapy of cancer patients but also to forecast radiation exposure risks. The aim of this study was to devise a machine learning method to stratify radiosensitivity and to investigate its association with copy number variations (CNVs) as markers of sensitivity to ionizing radiation. We used the Affymetrix CytoScan HD microarrays to for CNV estimation. Celluar radiosensitivity was measured by the clonogenic surviving fraction at 2 Gy (SF2).

Affymetrix SNP array data for myelodysplastic syndromes (MDS) samples

Project description:The progressive mechanism of myelodysplastic syndrome (MDS) remains unknown. We report that ROBO1 and ROBO2 are identified as novel progression-related somatic mutations using whole-exome and targeted sequencing in six of 16 (37.5%) paired MDS patients undergoing disease progression. To investigated the effect of ROBO1 or ROBO2 on ROBO1/2 CN number and LOH, we employed a Cytosan 750K chip to analyze the copy-number variations (CNVs) and loss of heterogeneity (LOH) in MDS patients with ROBO1&2 mutations. Copy number and LOH analysis of Affymetrix CytoScan 750K array was performed for 14 MDS patients with ROBO1 or ROBO2 mutations

Copy number variation analysis of a fetus with Silver-Russell syndrome in China

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.

Posterior Amorphous Corneal Dystrophy Is Associated with a Deletion of Small Leucine-rich Proteoglycans on Chromosome 12

Project description:Posterior amorphous corneal dystrophy (PACD) is a rare, autosomal dominant disorder affecting the cornea and iris. After next-generation sequencing of the family in which linkage analysis identified a chromosomal locus for PACD on 12q21.33 failed to yield a pathogenic mutation, array-based copy number analysis and qPCR detected a deletion on 12q21.33 containing four genes encoding small leucine-rich proteoglycans (SLRPs): KERA, LUM, DCN, and EPYC. Two other families with PACD also demonstrated deletion of these SLRPs, which together with murine models of KERA, LUM, and DCN deficiency provide convincing evidence that PACD is caused by haploinsufficiency of these SLRPs. Copy number analysis of 750K SNP and 1.9 non-polymorphic probes present on the Affymetrix CytoScan HD array. Samples were separated by affection status. Eight unaffected and 5 affected samples from across 3 families were analyzed. Analysis was performed using the Affymetrix Chromosome Analysis Suite (ChAS) v.2.0 software.
