For example, in the seven cancer types (BLCA, ESCA, HNSC, KIRC, LIHC, STAD and UCEC) with both grade phenotype information and normal control samples, expression of AURKB, BUB1, FOXM1, HMMR, MYBL2, and PLK1 follows the pattern in five cancer types (BLCA, HNSC, KIRC, LIHC, and UCEC) (Figure 7B). This evidence concerns the gene AURKB and bladder transitional cell carcinoma.
