Specific to bladder carcinoma, according to Han et al.,108 METTL3 may have an oncogenic role via the interactive process with DGCR8, the microprocessor protein, and positive modulation for the pri-miR221/222 procedure as dependent on m6A, probably shedding light on bladder cancer therapy. The gene discussed is DGCR8; the disease is urinary bladder carcinoma.
