Only eight genes were differentially expressed in BLCA and associated with prognosis, namely, the genes encoding C-X-C motif chemokine ligand 12 (CXCL12), Serpin family B member 17 (SERPINB7), cysteine-rich secretory protein LCCL domain-containing 2 (CRISPLD2), EMAP-like 1 (EML1), transient receptor potential cation channel subfamily C member 4 (TRPC4), solute carrier family 16 member 3 (SLC16A3), ANLN, and katanin catalytic subunit A1-like 1 (KATNAL1) (Figure 2(b)). Here, CRISPLD2 is linked to bladder transitional cell carcinoma.
