An integrated analysis of miRNA and gene copy numbers in xenografts of Ewing's sarcoma

Abstract excerpt

BACKGROUND: Xenografts have been shown to provide a suitable source of tumor tissue for molecular analysis in the absence of primary tumor material. We utilized ES xenograft series for integrated microarray analyses to identify novel biomarkers. METHOD: Microarray technology (array comparative genomic hybridization (aCGH) and micro RNA arrays) was used to screen and identify copy number changes and differentially...
