21, 24 The microarray data sources were obtained from the Gene Expression Omnibus (GEO).
Microarray data from different sources and platforms are publicly available, but integration is not straightforward, due to platform and experimental differences.
Microarray data from two sources (Figures 4, S2, and S3) supported the findings of the EST profiling results, as ubiquitous expression of both DIA1 and DIA1R was found, including expression in brain tissue.
Publically available microarray gene expression data sets were sourced from the NCBI gene expression omnibus (GEO) database (http://www.ncbi.nlm.nih.gov/geo/) and normalized data used to determine the relative levels of genes of interest using methods previously described [ 32].
We used microarray data from two sources for our analysis.
Moreover, RP has proved to be a robust method for comparing microarray data from different sources and experiments [20].
In the case of the Arabidopsis, Cell and Mouse eFP Browsers, we have mirrored publicly-available microarray data from several sources – described in the Data Sources and subsequent two sections – in our Bio-Array Resource [10].
Also, as the number of publicly available data sets increases (at the time of writing, GEO and Array Express host a total of 221,815 and 110,356 hybridizations, respectively), it is important to have reliable method to compare microarray data from different sources.
Others were based on microarray data from heterogeneous sources lacking systematic experimental controls [ 15] or were based on in silico predictions [ 14].
