Figure 5From: Identification of a small optimal subset of CpG sites as bio-markers from high-throughput DNA methylation profilesDNA methylation profiles of two signature CpG sites (TNF-1371 and TWIST1-524) from 12 lung cancer and 12 normal tissue samples in the testing dataset. The green color indicates low methylation level and red indicates high methylation level as shown on the right of the colormap.Back to article page
