Amazonia! is a free web interface that allows an easy query of public human transcriptome data by keyword in thematic pages and with list annotations.
Paradoxically, the tremendous downpour of microarray results prevents a simple use of expression data. Therefore, we propose a thematic entry to public transcriptomes: you may for instance query a gene on a "Stem Cells page", where you will see the expression of your favorite gene across selected microarray experiments related to stem cell biology. This selection of samples can be customized at will among the 6629 samples currently present in the database.
Every transcriptome study results in the identification of lists of genes relevant to a given biological condition. In order to include this valuable information in any new query in the Amazonia! database, we indicate for each gene in which lists it is included. This is a straightforward and efficient way to synthesize hundreds of microarray publications.
A special feature of Amazonia! is the field of human stem cells, notably embryonic stem cells. You can directly access the thematic page "Stem Cells" by clicking here.
