Fig. 2From: Discovery and validation of tissue-specific DNA methylation as noninvasive diagnostic markers for colorectal cancerRelationship between DNA methylation of promoter CpG sites and gene expression. A A four-way Venn diagram shows intersection of genes containing differentially methylated promoter CpG sites and differentially regulated genes. B Starburst plot shows integrating analysis of gene expression changes and DNA methylation changes of promoter CpG sites. Dots represent individual promoter CpG and the corresponding gene expression. Red dots indicate a total of 942 hypermethylated promoter CpG probes located in 264 downregulated genesBack to article page
