Mammalian genes have multiple functions in time and space during embryogenesis, aging, and in health and disease. This phenomenon of pleiotropic gene function is a major factor contributing to the increase of complexity from the mere number of approximately 25.000 protein-coding genes in the mammalian genome to the level of the organism. When and where a gene is expressed is an integral part of gene function. The profiling of gene expression and the study of gene regulation are therefore intriguing scientific objects of current biology. For a systems level approach to measure changes in transcript profiles in mouse models for human diseases we used microarray technologies and analysed transcriptome data from more than 1.100 DNA-chip experiments and 46 mutant mouse lines. Novel gene functions were revealed through the integration of multiple level data, including transcriptome, proteome, and metabolome in several mouse models.
