Dimensionality reduction plots for TCGA expression and methylation data. (A) MDS plot for normalized expression values of BrCa and normal breast tissue samples (left); PCA plot for level 3 beta methylation values of the same phenotypes (right). (B) MDS plot for normalized expression values of stage I BrCA and normal tissues (left); PCA plot for level 3 beta methylation values of the same phenotypes (right). (C) MDS plot for normalized expression values of advanced and early BrCA tissues (left); PCA plot for level 3 beta methylation values of the same phenotypes (right). MDS: Multidimensional scaling; PCA: principal component analysis.
