Access gene expression results from more than 3,000 experiments
Expression Atlas provides gene expression results on more than 3,000 experiments from 40 different organisms, including metazoans and plants.
Although human experiments represent one third of Expression Atlas, we cover other animal species such as chicken, pig, cow or sheep.
Plant experiments represent one fourth of Expression Atlas with more than 700 experiments. Apart from Arabidopsis thaliana, that is the species more represented, Expression Atlas contains experiments from other 17 plant species such as rice, wheat, maize, tomato or potato.
All data are manually curated
Expression Atlas contains thousands of selected microarray and RNA-sequencing datasets that are manually curated by PhD biologists. Curation in Expression Atlas consists of a critical review of each dataset to provide a comprehensive representation of gene expression data.
We extract and structure information from the literature to accurately represent each experiment and to enrich the annotation of each sample. We add more metadata to samples to better describe both, biological and technical information.
