Project description:Characterization of 68 cell lines derived from human sarcoma and 5 normal counterpart cells, including drug sensitivity testing, gene expression profiling and microRNA expression profiling have been completed. Data and tools for searching these data will be made publicly available through the NCI Developmental Therapeutics Program. The raw data (.cel files ) are provided through the GEO website. Sarcoma represents a variety of cancers at arise from cells of mesenchymal origin and have seen limited treatment advances in the last decade. Drug sensitivity data coupled with the transcription and microRNA profiles of a cohort of sarcoma cell lines may help define novel treatment paradigms. For each cell line, exon expression was measured using Genechip Human Exon 1.0 ST arrays from Affymetrix, interrogating > 1 million exon clusters, to provide comprehensive coverage of the entire genome at the exon and gene expression level. Please note that there are 2 replicates included in the study: Arrays 1 (GSM1676295) and 49 (GSM1676338) are replicates of the A-204 cell line Arrays 9 (GSM1676369) and 50 (GSM1676340) are replicates of the ES-4 cell line The sample titles represent are the cell line names (e.g. A-204, EW8 etc.). The drug screening data and details are provided in the 'NCI-Sarcoma-median-log10-IC50.csv' and 'drug_screening_readme.txt', respectively.

Project description:Reference materials are vital to benchmarking the reproducibility of clinical tests and essential for monitoring laboratory performance for clinical proteomics. The reference material utilized for mass spectrometric analysis of the human proteome would ideally contain enough proteins to be suitably representative of the human proteome, as well as exhibit a stable protein composition in different batches of sample regeneration. Previously, The Clinical Proteomic Tumor Analysis Consortium (CPTAC) utilized PDX-derived comparative reference (CompRef) materials for the longitudinal assessment of proteomic performance, however, inherent drawbacks of PDX-derived material has resulted in efforts to identify a new source of CompRef material. In this study, we examined the utility of using a panel of seven cancer cell lines, NCI-7 Cell Line Panel, as a reference material for mass spectrometric analysis of the human proteome. Our results showed that not only is the NCI-7 material suitable for benchmarking laboratory sample preparation methods, but NCI-7 sample generation is highly reproducible at both the global and phosphoprotein levels. In addition, the predicted genomic and experimental coverage of the NCI-7 proteome suggests the NCI-7 material may also have applications as a universal standard proteomic reference.
Project description:NCI60 proteome resource is a web application that facilitates comprehensive proteome analysis of the NCI-60 cell line panel. The NCI-60 is a set of 60 (now 59) human cancer cell lines from nine different tissues introduced in 1990 by the US National Cancer Institute (NCI) to screen for new anticancer agents.
The current database comprises a very high proteome coverage (more than half of human genome) and serves as a reference expression profiles of NCI-60 cell line panel. As such it contains details about protein and peptide identifications together with the corresponding fragment spectra and quantitative information. It also contains chromosome-centric view to identify the abundance and distribution of proteins whose genes are co-located on the same chromosome. In addition, a simple interface allows to query for differential protein expression either by protein names or attributes such as ontology terms. The protein queries return the cell lines where protein expression has been reported.
Project description:The NCI-60 cell line collection is a very widely used panel for the study of cellular mechanisms of cancer in general and in vitro drug action in particular. It is a model system for the tissue types and genetic diversity of human cancers and has been extensively molecularly characterized. Here, we present a quantitative proteome and kinome profile of the NCI-60 panel covering, in total, 10,350 proteins (including 375 protein kinases) and including a core cancer proteome of 5,578 proteins that were consistently quantified across all tissue types. Bioinformatic analysis revealed strong cell line clusters according to tissue type and disclosed hundreds of differentially regulated proteins representing potential biomarkers for numerous tumor properties. Integration with public transcriptome data showed considerable similarity between mRNA and protein expression. Modeling of proteome and drug-response profiles for 108 FDA-approved drugs identified known and potential protein markers for drug sensitivity and resistance. To enable community access to this unique resource, we incorporated it into a public database for comparative and integrative analysis (http://wzw.tum.de/proteomics/nci60).
