Project description:Desmoplastic malignant mesothelioma is a rare tumor. Due to the rarity, genomic profile of desmoplastic malignant mesothelioma is not unveiled. To elucidate genomic profile of desmoplastic malignant mesothelioma, we used illumina infinium omini exomeexpress in an established patient-derived cell line of desmoplastic malignant mesothelioma.

Project description:Desmoplastic malignant mesothelioma is a rare tumor. Due to the rarity, development of new treatment for desmoplastic malignant mesothelioma is difficult. To develop new treatment strategy using existing anti-cancer drugs, kinase activity profiling has not been thoroughly studied. We used PamChip array to identify the peptide profiles of desmoplastic malignant mesothelioma between the patient-derived cell line and the tumor tissue.

Project description:Malignant mesothelioma (MM) is an asbestos-related malignancy. MM cells have a broad histological spectrum, and consist mainly of epithelioid, sarcomatoid, and biphasic cell types. The prognosis of MM is generally poor. We applied a copy-number analysis to the identification of new fragile genes in regions 3p21 and 16p13.3 in MM.

Project description:Malignant mesothelioma (MM) is an asbestos-related malignancy. Discrimination between MM and reactive mesothelial hyperplasia (RM) is often difficult. MM cells have a broad histological spectrum, and consist mainly of epithelioid, sarcomatoid, and biphasic cell types. The prognosis of MM is generally poor, but better prognosis has been reported with the epithelioid type of MM than the non-epithelioid type. We applied a genome-wide analysis to the identification of new markers that may aid in differentiating the epithelioid type of MM from other histological types and from RM cells. Array-based comparative genomic hybridization analysis was performed on malignant mesothelioma (MM) primary cell cultures, reactive mesothelial hyperplasia (RM) primary cell cultures; early passage of in vitro primary cell cultures to minimize acquisition of additional genomic changes. If available, matched peripheral blood was applied to analysis.

Project description:SNP array data from 45 cell lines of Malignant Pleural Mesothelioma were used to explore recurrent copy number alterations. This study was part of Cartes d'Identité des Tumeurs (CIT) project from the french Ligue Nationale Contre le Cancer.

Project description:Malignant Peritoneal Mesothelioma (PeM) is a rare but frequently fatal cancer that originates from the peritoneal lining of the abdomen. Standard treatment of PeM is limited to cytoreductive surgery and/or chemotherapy, and no targeted therapies for PeM yet exist. This study performs comprehensive integrative analysis of genome, transcriptome, and proteome of treatment-naïve PeM tumors with the aim of identifying mesothelioma-related molecular alterations and potentially identifying novel treatment strategies.

Project description:To identify regions that display DNA copy number alterations in malignant pleural mesothelioma (MPM), we carried out array comparative genomic hybridization (CGH) analysis with 14 MPM cell lines. Regions of genomic aberrations observed in >20% of individuals were 9p21.3, 13q12.11, 16p13, and 22q12.2 of losses. The most frequent alteration was 9p21.3, which include the p16INK4/p14ARF. The loss of 22q12.2 regions include the NF2 was observed in 3 out of 14 cell lines. In 3 cell lines, loss of 13q12.11 region which contains Large Tumor Suppressor, homolog 2 (LATS2) was detected. Human malignant pleural mesothelioma cell lines were profiled on Agilent 244K aCGH arrays according to manufacturer’s instructions. Pooled normal human genomic DNA was used as the reference.

Project description:Integrated profiling of somatic molecular alterations present in tumors is necessary to further our understanding of the tumorigenic process. We investigated the potential relationships between gene copy number alterations and DNA methylation profiles in a case series of pleural mesotheliomas (n=23). Gene copy number (CN) alterations profiled with 500K SNP arrays and DNA methylation measured at over 750 cancer-related genes with methylation bead-arrays were examined concomitantly. Considering each probed locus, there were no instances of significantly correlated CN alteration and methylation (no loci with Q < 0.05) and averaging loci over their associated genes revealed only two genes with significantly correlated CN and methylation alterations (Q < 0.04). In contrast to the lack of discrete correlations, the overall extent of tumor CN alteration was significantly associated with DNA methylation profile when comparing CN alteration extent among methylation profile classes (P < 0.02), and there was evidence that this association was partially attributable to prevalent allele loss observed at the maintenance DNA methyltransferase DNMT1. Taken together, this work indicates a strong association between global genetic and global epigenetic dysregulation in mesothelioma rather than a discrete, local coordination of gene inactivation, and further highlights the utility and necessity of integrative genomics approaches in cancer biology.
