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
Project description:In this study, we investigated CNAs of 20 primary clear cell renal cell caricinomas (ccRCCs), 20 corresponding metastases and another subsets of 30 primary ccRCCs by 44k oligonucleotide-based array comparative genomic hybridization (array CGH).
