Based on these findings, we classified the five IAP members into three groups (1, cIAP1-N+Survivin-N; 2, cIAP1-C+cIAP2+XIAP; and 3, Survivin-C+Livin) and analyzed their corresponding clinical and pathological parameters in bladder cancer. The gene discussed is XIAP; the disease is urinary bladder carcinoma.
