Figure 2

Normalized relative expression ratios of genes across all samples. Primary samples are on the left panels and grouped along the horizontal axis by tissue type according to the following colour codes: renal tumours (LIGHT BLUE), renal normals (DARK BLUE), colorectal tumours (DARK GREEN), colorectal normals (LIGHT GREEN), breast tumours (PINK), breast normals (RED), bladder tumours (YELLOW), bladder normals (ORANGE), glioblastomas (BLACK), ovarian tumours (GREY). Cell line samples are on the right panels and are also grouped by tissue type: ovarian (GREY), breast (PINK) and colorectal (DARK GREEN). The y axis shows the expression ratios on a log2 scale. The horizontal dashed lines represent an averaged one standard deviation (-0.4 to 0.4) gaussian noise level arising from unstable housekeeping gene expression across the whole sample set. The vertical distance between the two dashed lines represents therefore a zero centred 70% average confidence interval for all the expression values.
