Fig. 4

Dot density plots showing the distribution of gene-specific and global methylation levels. T: tumor tissue; A: tumor-adjacent tissue; D: tumor-distant tissue; N: normal breast tissue from healthy controls. Red line: arithmetic mean. Due to the low LOD and LOQ of the assay for PTEN and the low frequency of methylation in tumors, tumor-adjacent and tumor distant-tissues were analyzed only randomly
