TiGER (Tissue-specific Gene Expression and Regulation) is a database that provides comprehensive information about postnatal human tissue-specific gene regulation, including expression (from EST studies) and regulatory elements. The database contains tissue-specific gene expression profiles or expressed sequence tag (EST) data, cis-regulatory module (CRM) data, and combinatorial gene regulation data. In LifeMap database, only genes that were categorized as 'tissue specific' are presented. For further information, please refer to Tiger webpage.
