From: DNA methylation profiles of bronchoscopic biopsies for the diagnosis of lung cancer
Hierarchical cluster analyses and principal component analysis of surgical specimens. 1303 differentially methylated loci identified by a DMA of paired biopsies were analyzed in the surgical specimens' data set by performing a hierarchical cluster analysis (a) or PCA (b). Heatmap and PCA: red boxes/spheres: tumor samples, green: control tissue samples; heatmap: yellow: high, blue: low DNA methylation values
