RT-qPCR assays in Figure 1A revealed the highest levels of MT2A in T24 cells as compared to the other three bladder cell lines (RT4, HT1376, and TSGH-8301), which is contrary to the results of an earlier study in MT3 [9], suggesting that MT2A and MT3 expressions in bladder carcinoma cells are due to the cellular type but not related to the extent of neoplasia in vitro. Here, MT2A is linked to urinary bladder carcinoma.
