FIGURE 2.
The analysis of multiple breast lesions from patient BP18 displays heterogeneity in APC, CDH1 and CTNNB1. Slide BP18-6 shows a DCIS (A) and an IDC (B), BP18-9 displays two DCIS (A and B) and BP18-7 an IDC. The target gene/ACTB ratio for APC, CDH1 and CTNNB1 are indicated for each of the genes. APC methylation is present in all the lesions with ratios above the cut off of 20.73; CDH1 methylation was above the cut-off of 8.10 only in BP18-9 and CTNNB1 methylation levels were above the cut-off of 2.65 for BP18-9B and BP18-7
