Figure 6
P values from ANOVA analysis of each of the 70 signature genes. For each tumor the log10 ratios of the 70 signature genes were averaged for each dye-swapped hybridization pair, after reversing the sign of one of the dye swaps. An ANOVA analysis was then performed for each individual gene for each tumor, to determine if the log ratios for each gene varied by hybridization site or by labeling site. The plots show the number of genes for each tumor having P values of < 0.001, 0.001–0.01, 0.01–0.05, and 0.05–1.0 from the ANOVA analysis, when grouped by hybridization site (left) or by labeling site (right).
