Cross-platform comparison of transcriptional expression profiles of ovarian cancer using MCIA. (A) Visualization of the concordance of patient gene expression profiles from multiple platforms. The samples are colored according to four subtypes of patients . Axis 1 clearly separates the proliferative and immunoreactive subtypes, whereas the mesenchymal and differentiated subtypes are separated by axis 2. The inset represents the pseudo-eigenvalues of each dataset on the first two PCs. (B-E) Show the coordinates of genes from each platform. Top consensus genes, common to all platforms from the end of each axis, are colored and labeled.
