YTHDC1 and urinary bladder carcinoma: In a panel of in vitro cell lines, including the normal cell line: SV‐HUC‐1, and the bladder cancer cell lines: T24, U3, 5637, J82 and RT4, higher level of YTHDC1 was observed in SV‐HUC‐1 cells compared with that in bladder cancer cells, whereas in bladder cancer cells, varied expression of YTHDC1 was observed (Figure S3J,K).
