Moreover, eukaryotic translation initiation factor 3 subunit A (EIF3A), DDX21, SDE2, transportin 1 (TNPO1), and ring finger protein 40 (RNF40) are thought to mediate multiple alternative splicing events in bladder cancer, implying their essential roles in the development and progression of this disease (114). The gene discussed is TNPO1; the disease is urinary bladder cancer.
