GXD: a Gene Expression Database for the laboratory mouse: current status and recent enhancements

The Gene Expression Database (GXD) is a community resource of gene expression information for the laboratory mouse. The database is designed as an open-ended system that can integrate different types of expression data. New expression data are made available:on a daily basis. Thus, GXD provides increasingly complete information about what transcripts and proteins are produced by what genes; where, when and in what amounts these gene products are expressed; and how their expression varies in different mouse strains and mutants. GXD is integrated with the Mouse Genome Database (MGD), Continuously refined interconnections with sequence databases and:with databases from other species place the gene expression information in the larger biological and analytical context. GXD is accessible through the Mouse Genome Informatics Web site at http://www, infopmatics.jax.org/ or directly at http://www.informatics. jax.orgimenus/expression_menu.shtml.
