Differential expression induced by tissue state changes.

<p>(<b>A</b>) Pairwise analysis. For each paired tissue, the SAM-FDR method is applied and leads to the identification of a number of probesets that show significant differential expression (FDR = 20%). The red number in brackets indicates how many differential expressed probesets are specific to the tissue. Uterus normal versus tumor comparison gives no result and consequently does not appear in the table. (<b>B</b>) Scatter plots of expression values. Normal versus tumor normalized expression values of differential expressed probesets are draw for each tissue pair. The statistically significant absence of differential expression is represented by the diagonal line (y = x). Red plots refer to tissue-specific probesets (previously mentioned using red numbers in bracket in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040194#pone-0040194-g002" target="_blank">Figure 2A</a>).
