Database Description

The GPX Macrophage Expression Atlas (GPX-MEA) is an online resource for expression based studies of a range of macrophage cell types following treatment with pathogens and immune modulators. GPX Macrophage Expression Atlas (GPX-MEA) follows the MIAME standard and includes an objective quality score with each experiment. It places special emphasis on rigorously capturing the experimental design and enables the statistical analysis of expression data from different micro-array experiments. Studies may be queried on the basis of experimental parameters, sample information and quality assessment score. The ability to compare the expression values of individual genes across multiple experiments is provided. In addition, the database offers access to experimental annotation and analysis files and includes experiments and raw data previously unavailable to the public. This is the first example of a focussed macrophage gene expression database that allows efficient identification of transcriptional patterns which provide novel insights into biology of this cell system. GPX-MEA is available through the GPX website at (
