Down-regulation of mRNA expression in human chromosomal region 18q21.2-18q23 – the BCL2 region (patient counts with coordinate down-regulation). Grayscale cross-comparison plot of down-regulation patterns across patients (analogous to Figures 8, 11, 14). View this plot in conjunction with Figures 24 and 25. Note, that many more patients show down-regulation as indicated by dark spots in this plot than up-regulation as indicated by dark spots in Figure 25. This region has been reported in other studies to be frequently deleted in colon cancer (see Table 4). Note the expression down-regulation of BCL2. SMAD4 (Hs.298320) and TCF4 are only weakly down-regulated. The DCC gene is also located in this region between LOC51320 and MBD2 but no informative expression measures were obtained.
