TNFAIP3 and urinary bladder carcinoma: circ0008399/WTAP promotes TNFAIP3 expression by increasing m6A-dependent TNF alpha induced protein 3 (TNFAIP3) mRNA stability in bladder cancer cells, which in turn inhibits bladder cancer cell apoptosis and mediates reduced bladder cancer chemosensitivity to cisplatin [129].
