ACGH Detects Copy Number Variation with Similar Resolution to PacBio Sequencing Approaches

ABSTRACT: This study examines genomic copy-number variation between two African cichlid species through array comparative genomic hybridization. Probe level hybridization ratios were compared to copy number variation identified in Illumina and Pacific Biosciences genome assemblies from both species. Array comparative genomic hybridization was performed with 3 samples (1 replicate array setup) of genomic DNA from Maylandia zebra vs. Orechromis niloticus XX clone genomic DNA from University of Stirling clonal lines.

Chordoma_32k_1Mb

Project description:Frequent deletion of the CDKN2A locus in chordoma: analysis of chromosomal imbalances using array comparative genomic hybridization DNA copy number analysis of 21 fresh frozen chordoma biopsies, and the respective relapse in four of them, using 32k and 1Mb array CGH. All cases showed copy number alterations and primarily deletions of chromosomal regions were found. Particularly, the CDKN2A and CDKN2B loci in 9p21 were homo- or heterozygously lost in 70% of the tumors. Keywords: chordoma, array comparative genomic hybridization

Array-comparative genomic hybridization by using DualChip® human cancer 1.1 arrays

Project description:Tumors often harbor several genetic aberrations at both RNA and DNA level. Integration of expression data with copy number changes represents a powerful strategy to investigate genes involved in tumorigenesis. Here we describe a fluorescent array-based Comparative Genomic Hybridization protocol to be used on a commercial microarray platform optimized to detect cancer-related gene expression. This method will be valuable to use a single low-density array platform monitoring gene expression and copy number assessment in parallel. Keywords: Comparative genomic hybridization, neuroblastoma

DNA copy-number changes

Project description:Gene amplifications and deletions frequently contribute to tumorigenesis. Characterization of these DNA copy-number changes is important for both the basic understanding of cancer and its diagnosis. Comparative genomic hybridization (CGH) was developed to survey DNA copy-number variations across a whole genome. With CGH, differentially labelled test and reference genomic DNAs are co-hybridized to normal metaphase chromosomes, and fluorescence ratios along the length of chromosomes provide a cytogenetic representation of DNA copy-number variation. CGH, however, has a limited ( approximately 20 Mb) mapping resolution, and higher-resolution techniques, such as fluorescence in situ hybridization (FISH), are prohibitively labour-intensive on a genomic scale. Array-based CGH, in which fluorescence ratios at arrayed DNA elements provide a locus-by-locus measure of DNA copy-number variation, represents another means of achieving increased mapping resolution. Published array CGH methods have relied on large genomic clone (for example BAC) array targets and have covered only a small fraction of the human genome. cDNAs representing over 30,000 radiation-hybrid (RH)-mapped human genes provide an alternative and readily available genomic resource for mapping DNA copy-number changes. Although cDNA microarrays have been used extensively to characterize variation in human gene expression, human genomic DNA is a far more complex mixture than the mRNA representation of human cells. Therefore, analysis of DNA copy-number variation using cDNA microarrays would require a sensitivity of detection an order of magnitude greater than has been routinely reported. We describe here a cDNA microarray-based CGH method, and its application to DNA copy-number variation analysis in breast cancer cell lines and tumours.
