Principal component plots illustrating the relationship between cancer type and gene-expression levels. Values for the first two principal components are shown. Each point represents data across all genes for a given tumor sample. The colors and legend indicate the cancer type of each tumor sample. a Distinct, tissue-specific patterns were present in the original data. b After a regression-based adjustment for cell-type effects, these patterns were no longer prominent in the data. Cancer type abbreviations are listed on the TCGA web site
