Plots of probe intensities and segmented averages for cancer interesting genes.

<p><b>A.</b> CDKN2A and flanking sequence on chromosome nine for six cell lines. The central vertical lilac region delineates the gene location. <b>B</b>. MYC and flanking sequence on chromosome eight for five cell lines. The central vertical lilac region delineates the gene location. <b>C</b>. ABCB1 (MDR1), ABCB4 and flanking sequence on chromosome 7 for the parental OVCAR_8 and its drug-resistant derivative NCI_ADR_RES. The green and pink central vertical regions delineate the locus of ABCB1 and ABCC4, respectively. In A, B, and C the x-axis is the nucleotide location. The y-axis values on the left are the average log intensity ratios, and on the right are estimated DNA copy numbers. The black horizontal lines show the average log intensity ratio in each segment while the brown points show the log intensity ratios for each probe.
