NCI Biomedical Informatics Blog
|On This Page|
The National Cancer Informatics Program (NCIP) will continue to make data portals and collections developed or supported as part of the NCI cancer Biomedical Informatics Grid® (caBIG®) program available to the biomedical-informatics and cancer-research community.
In some instances, the data portals and collections listed here were created using specific caBIG-developed applications as the basis for their structure and functionality. These include the caArray Data Portal, the caIntegrator Data Portal, the Cancer Genome Workbench, and the National Biomedical Imaging Archive (NBIA).
In other instances, caBIG program staff collaborated with other NCI divisions, offices, or centers, other NIH entities, academic centers, or private organizations to provide the informatics infrastructure needed to manage and disseminate large, complex data collections. This group includes the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) study, The Cancer Genome Atlas (TCGA), the Investigation of Serial Studies to Predict Your Therapeutic Response with Imaging And moLecular Analysis (I-SPY I) trial, the Cancer Models Database (caMOD), the cancer Nanotechnology Laboratory (caNanoLab) Portal, the REpository for Molecular BRAin Neoplasia DaTa (REMBRANDT), the Cancer Genome Anatomy Project (CGAP), and the Pathway Interaction Database (PID).
Because several of these collections are dynamic — investigators are continuing to submit data to them — this list will be updated on a regular quarterly basis. Any new data collections created using NCIP resources will be listed here as well, so monitor this page frequently.
The NCI CBIIT instance of the caArray Data Portal provides researchers with access to public data sets generated by 183 microarray experiments. While most of the data sets are derived from samples of human disease, other organisms are represented in the collection: Drosophila melanogaster, Mus musculus, and Rattus norvegicus. Assay types include
- Gene expression
- Comparative genomic hybridization (copy-number changes)
- Single-nucleotide polymorphism (SNP)
- Exon (alternative splicing)
Two experiments (woost-00035 for SNP profiling data; woost-00041 for transcript profiling data) provide gene-expression data for a panel of more than 300 cancer cell lines that GlaxoSmithKline (GSK) released to NCI in 2008. The SNP data and transcript data can be downloaded via ftp.
Cancer types represented in the caArray data sets are too numerous to be listed here, but researchers can quickly identify those of interest through a simple search. The caArray Data Portal search function is based on entering a keyword in conjunction with choosing a field from one of two categories: "Experiments" or "Samples." See the caArray User's Guide.
caArray is continuing to accept data submitted by members of the community.
