Figure 5.
Methylation analysis of human ERα CpG island by MSO microarray. Summaries of the MSO results are shown for six breast cancer cell lines, one normal human fibroblast cell strain (HFF), four normal (N) breast tissue samples, and 15 primary breast tumors (T). Gray scale shown at right represents the methylation levels in percentage determined from the calibration curve for the test CpG sites (see example in Fig. 3).
