SH3BP2 and bladder transitional cell carcinoma: We identified a panel of 9-core differentially expressed genes (DEG) including MMP9, PDGFRA, AHNAK, OLR1, RAC3, IGF1, PGF, OAS1, and SH3BP2. Using these 9-core DEG, we set up a model to evaluate prognosis of patients with bladder urothelial carcinoma.
