P2RX6 and bladder transitional cell carcinoma: The higher expression of P2RX6 (p = 0.039, in BRCA), RNF123 (p = 0.03, in CESC), CASK (p < 0.0001, in LGG), DGKG (p = 3E-04, in STAD), RBM45 (p = 0.043, in LUSC), and KCNH8 (p = 0.00012, in UCEC) was associated with worse survival, while the higher expression of PDGFD (p = 0.046, in BLCA), SCG3 (p = 0.036, in LGG) and FSD1 (p = 0.0025, in LGG) was associated with better survival.
