About The Gene Expression Atlas Project

The Gene Expression Atlas (ArrayExpress Atlas) is a semantically enriched database of meta-analysis based summary statistics which serves queries for condition-specific gene expression patterns (e.g. genes over-expressed in a particular tissue or disease state) as well as broader exploratory searches for biologically interesting genes/samples. It is based on a subset of the ArrayExpress data.

Gene Expression Atlas goals:

1. Provision of a statistically robust framework for integration of gene expression experiment results across different platforms at a meta-analytical level
2. A simple interface for identifying strong differential expression candidate genes in conditions of interest
3. Integration of ontologies for high quality annotation of gene and sample attributes
4. Construction of new gene expression summarized views, with a view to analysis of putative signalling pathway targets, discovery of correlated gene expression patterns and the identification of condition/tissue-specific patterns of gene expression.

Additional help for the Gene Expression Atlas is available:

• Help searching the database and interpreting the results
• Details about the construction of the Atlas
• Programmatic access to the Atlas
• Frequently asked questions

We will work on expanding and improving the Atlas, there is a monthly release with new data and new features are added to the interface resgularly. Keep your eye on the Atlas Blog at http://arrayexpress-atlas.blogspot.com for the latest news and views from the cockpit.
