SMPD4 and urinary bladder carcinoma: Sequentially, transcript levels of the abovementioned genes (ST18, FOXN1, SMPD4, MSTN, LINC00482, S100A4, MZB1, SFTPB, GALNT5, and CACYBP were upregulated genes, LINC01719, GRASP, STC2, CLP1, SGK2, WNT5A, PRR16, NR4A2, GLIPR1, and KIAA1551 were downregulated genes) were also measured in five pairs of bladder cancer and adjacent normal tissues by RT-qPCR (Figure 6B).
