Reporter assays using the MT2A and HO-1 reporter vectors with a specific human MT2A and HO-1 promoters, respectively, revealed that CAPE induced MT2A (Figure 5B) and HO-1 (Figure 5C) reporter activities dose dependently in bladder carcinoma HT1376 and TSGH-8301 cells. Here, MT2A is linked to urinary bladder carcinoma.
