The X-axis represents chromosome number (1 – 22) and the Y-axis represents the genome-wide frequencies of gains (> 0.25 of intensity ratio) and losses (< 0.25 of intensity ratio) for each clone of NSCLC are shown. Vertical lines indicate chromosomal boundaries. (A) Frequencies of genes increased in copy number or decreased in copy number in SCC of the lung. (B) Frequency of gene copy number abnormalities in the AC. Gains and losses are shown as green and red color bars, respectively, which indicate the overall chromosomal copy number aberrations detected.
