* In bold the intersection of two gene lists indicating the modulated genes for a dye combination as percentage of all modulated genes (20 genes) found by analysis of all dye combinations combined. In italics the intersection of three gene lists indicating the modulated genes for two dye combinations as percentage of all modulated genes found for all dye combinations combined. The first dye was used for B[a]P treatment, the second for the control.
