From: DNA methylation-dependent silencing of CST6 in human breast cancer cell lines

Methylation analysis of the CST6 proximal promoter and exon 1 in CST6-negative breast cancer cell lines that have been exposed to demethylating treatment. A summary of the methylation analysis of the CST6 promoter (14 CpGs) and exon 1 (32 CpGs) is shown. Black circles correspond to fully (100%) methylated CpGs, gray circles correspond to CpGs with intermediate methylation, and open circles correspond to unmethylated CpGs. TMI values for the promoter/exon 1 region (46 CpGs) are given for each breast cancer cell line. (a) CpG methylation analysis of the CST6 promoter/exon 1 region after treatment with 5-aza. (b) CpG methylation analysis of the CST6 promoter/exon 1 region after withdrawal of 5-aza treatment.
