The analysis of various bladder cancer cell lines (T24, 253 J, J82, 5637, RT-4) and an immortalized bladder epithelial cell line (SV-HUC-1) showed consistent results, with bladder cancer cell lines exhibiting lower MARCH7 expression compared to the control cell line (Fig. 1F). Here, MARCHF7 is linked to urinary bladder carcinoma.
