MT3 and urinary bladder carcinoma: 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.
