    Amazonia! 6462 human microarray datasets

    6th March 2011

    Amazonia!Amazonia! – explore the jungle of microarray results

    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 6462 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.

    Overlaying gene expression data onto pathways from databases

    5th November 2010

    Superimposing gene expression data onto pathways from databases is a common task in the final steps of microarray data analysis – that is, biological interpretation and results discussion.

    I have found many tools which claim to facilitate this procedure. Some of them are reviewed below (in no specific order).
