Frequency of copy number changes in chromosome 17 by array CGH in 28 CCC. (A) chromosome 17 is represented by ideograms showing G-banding patterns. Bold vertical lines on the ideogram indicate the region of chromosomal amplification. The number at the top of each line represents the primary tumor in which the indicated change was recorded. Nine samples showed 17q23-25 amplification that included miR-21. (B) The gains and losses are shown as green and red color bars, respectively. These samples showed 17q23-25 amplification that included miR-21.
