Methylation analysis of the kinases promoters showing methylated and unmethylated bands.

<p>A) <i>SRC</i> promoter methylation analysis, in which samples 1 and 2 presented hypomethylated promoter, sample 3 presented partial methylation and sample 4 presented hypermethylated promoter; B) <i>LYN</i> promoter methylation analysis, in which samples 1 presented hypomethylated promoter, sample 2 presented partial methylation and samples 3 and 4 presented hypermethylated promoter; C) <i>CKB</i> promoter methylation analysis, in which samples 1 and 2 presented hypermethylated promoter, and samples 3 and 4 presented hypomethylated promoter. C–: blank; C+: positive control, gDNA sample completely methylated; U: PCR with unmethylated primer set; M: PCR with methylated primer set; MW: molecular weight marker; bp: base pairs.
