Genomic profiles of breast cancer cell lines. (a) Whole genome frequency analysis copy number gain (red), copy number loss (green), loss of heterozygosity/allelic imbalance (AI) (top blue) and copy number neutral LOH/AI (bottom blue). Vertical lines through all four graphs represent the genomic location of key breast cancer genes, using the hg18 build of the human genome map. (b) Illustration of copy number and LOH/AI status for ESR1, BRCA1, BRCA2, ERBB2 and TP53 in each of the samples. Each of these DNA events is evident in all of these genes. 65 HCC2218 BT474 MCF7 BRCA2 TP53 ERBB2 BRCA1
Figure 3.2. Quantitative and qualitative benefits of integrative analyses. (a) Heatmap and bar plot illustration of the additive benefit of multi-dimensional DNA analysis for the explanation of consequential differential gene expression. Within a sample, when sequentially adding a DNA dimension of analysis, an increasing percentage of observed differential gene expression can be explained. For each dimension or combination of dimensions, in the bar plot, the median value is used (grey bars). Heatmaps display the percentage of differential expression explained by DNA mechanisms, with values near to 100 either dark red (overexpression) or green (underexpression) and values closer to 0 in white. (b) Two specific genes GNAS and CASP1 are given as examples to show multiple and complementary mechanisms of gene disruption, illustrating the importance of multi-dimensional analysis (MDA). 66
