What's CGED?CGED (Cancer Gene Expression Database) is a database of gene expression profile and accompanying clinical information. The data of CGED were obtained through collaborative efforts of Nara Institute of Science and Technology, Osaka University Medical School, Kyoto University Medical School and Osaka Medical Center for Caner and Cardiovascular Diseases to identify genes of clinical importance. This database offers graphical presentation of expression and clinical data with similarity search and sorting functions. CGED includes data on breast (prognosis and docetaxel data sets), colorectal, hepatocellular, esophageal, thyroid, and gastric cancers (updated in March 2007).
Genes in CGED can be searched by 1) gene names or identifiers, or 2) gene ontology terms or keywords in functional annotations in the SwissProt (Example of search: breast cancer 1, catenin (gene names); A1BG (Symbol); V01512 (GenBank accession number); NM_001022 (RefSeq); kinase, polymerase (gene ontology term or SwissProt functional annotation)), or 3) cancer types and its clinical factors, or 4) gene expression differentials based on p value or q value.
The details of the resources, flat data files of CGED, and other information are presented at http://genome.mc.pref.osaka.jp/CGIP.html. CGED was compiled in the 2005 Database Issue of Nucleic Acids Research [PDF].
