COP1 and cervical adenocarcinoma: Corresponding our previous observation, except in HCT116 p53-/- human colorectal carcinoma cells and MDA-MB-231 human breast adenocarcinoma cells, infection of the HCT116 human colorectal carcinoma cells, T24 human urinary bladder carcinoma cells, MNT-1 human melanoma cells, HepG2 human hepatocellular carcinoma cells or HELA human cervical adenocarcinoma cells with BCG decreased the expression of TNF-α-responsive p53 and induced the COP1 expression (Figure 5D).
