Project description:We present the first computational approach to reconstruct the sequence of copy number alterations driving carcinogenesis from the analysis of several tumor samples of a same patient. Applied to BAC array-CGH and SNP array data from bladder and breast cancers, this method proved highly valuable to establish the clonal relationships between primary tumors and recurrences and to identify the chromosome aberrations at the initiation of tumorigenesis. This SuperSeries is composed of the following subset Series: GSE19189: SNP data from 20 bladder tumors GSE19193: CGH data from 58 bladder tumors Refer to individual Series

Project description:We present the first computational approach to reconstruct the sequence of copy number alterations driving carcinogenesis from the analysis of several tumor samples of a same patient. Applied to BAC array-CGH and SNP array data from bladder and breast cancers, this method proved highly valuable to establish the clonal relationships between primary tumors and recurrences and to identify the chromosome aberrations at the initiation of tumorigenesis. An algorithm was developed to reconstruct tumors lineage and the sequence of copy number alterations along tumorigenesis from the analysis of several samples from a same patient. The data here consist in Illumina SNP data from 20 bladder tumors. 15 of these tumors (REF1 to REF15) come from independent samples and were used to compute the frequencies of breakpoints at each location. The 5 other samples (S4_A, S4_B, S5_A, S5_B, and S5_C) are multiple tumors from 2 patients. They were used to reconstruct the sequence of chromosome aberrations along cancer development in these 2 patients.

Project description:41 lung adenocarcinoma from never-smokers hybridized on Illumina SNP arrays on 13 HumanCNV370-Quadv3 chips. High-resolution array comparative genomic hybridization analysis of lung adenocarcinoma in 41 never smokers for identification of new minimal common regions (MCR) of gain or loss. The SNP array analysis validated copy-number aberrations and revealed that RB1 and WRN were altered by recurrent copy-neutral loss of heterozygosity.The present study has uncovered new aberrations containing cancer genes. The oncogene FUS is a candidate gene in the 16p region that is frequently gained in never smokers. Multiple genetic pathways defined by gains of MYC, deletions of RB1 and WRN or gains on 7p and 7q are involved in lung adenocarcinoma in never smokers.

Project description:In this study, we characterize the fusion protein produced by the EPC1-PHF1 translocation in Low Grade Endometrial Stromal Sarcoma (LG-ESS) and Ossifying FibroMyxoid Tumors (OFMT). We express the fusion protein and necessary controls in K562 Cells. The fusion protein assembles a mega-complex harboring both NuA4/TIP60 and PRC2 subunits and enzymatic activities and leads to mislocalization of chromatin marks in the genome, linked to aberrant gene expression.
