Up-regulation of mRNA expression in human chromosomal region 8q11.23-q21.13 (patient counts with coordinate up-regulation). Grayscale plot of cross-comparison of up-regulation patterns across patients for gene pairs in a particular region. Both, horizontal and vertical axes comprise the same genes in chromosomal order. In each square total counts of patients with consistent up-regulation in two genes are coded by different shades of gray. Dark squared regions along the diagonal indicate coordinated regulation in patient subgroups. Note, that many more patients show up-regulation as indicated by dark spots in this figure than down-regulation as indicated by dark spots in Figure 8. The left region of exceptionally strong up-regulation spans TCEA1, LYPLA1, MRPL15, the known tumor gene LYN, and PLAG1. Note that TOX and ANKTM1 are down-regulated in approximately half of the tumor samples.
