Project description:Expression Profiling and Array Comparative Genomic Hybridization of Pancreatic Xenografts and Cell Lines
Project description:To directly compare genomic alterations between patient tumors and derived cell lines, both parental tumors and cell lines were characterized by array-based comparative genomic hybridization.
Project description:This SuperSeries is composed of the following subset Series: GSE25273: Array Comparative Genomic Hybridization of Pancreatic Xenografts and Cell Lines GSE26088: Expression Profiling of Pancreatic Xenografts and Cell Lines Refer to individual Series
Project description:Tumor-derived cell lines are used as in vitro cancer models, but their ability to accurately reflect the phenotype and genotype of the parental histology remains questionable, given the prevalence of documented cell line–specific cytogenetic changes. We have addressed the issue of whether copy number alterations seen in tumor-derived cell lines reflect those observed in studies of fresh tissue by carrying out a meta-analysis of array-based comparative genomic hybridization data that considers both copy number alteration frequencies and the occurrence of cancer gene amplifications and homozygous deletions. Keywords: comparative genomic hybridization
