In addition, we detected the MINDY1 protein levels in four bladder cancer cell lines (5637, UM-UC-3, T24 and BIU-87) and immortalized normal uroepithelial cell line (SV-HUC-1), exhibiting an upregulation tendency of MINDY1 in bladder cancer cell lines (Additional file 1: Figure S1). This evidence concerns the gene MINDY1 and urinary bladder cancer.
