Range of gene expression measured from the selected pathways. The bell curve represents the distribution of expression across the entire TCGA cohort, using Affymetrix array. The red ticks on the x-axis represent gene expression levels aggregated within a pathway from the 18 patients whose FFPE samples were measured using qPCR. The range of expression can be normalized across the Affymetrix and TaqMan qPCR platforms. Patient samples measured with qPCR have a range of expression that does not appear biased within the normal curve
