Expressed probes in the array according to gene type and sample group.

*To be considered “detected” a probe was measured with the ‘Well Above Background’ flag in at least five of six samples in at least one group.** Number of differentially expressed probes in each group: To be considered “differentially expressed” a probe should have a p-value ≤ 0.01 assigned by two different methods (SAM and RankProduct).***Probes were labeled as “unannotated” when not clearly categorized as coding or non-coding in the microarray annotation table.Expressed probes in the array according to gene type and sample group.
