TP53 and colon carcinoma: We have made similar observations with p53-WT A549 lung carcinoma, HCT116 colon carcinoma and MCF7 breast cancer cells, where exposure to low (i.e., CF-assay range) concentrations of cisplatin (≤10 μM for 72 h) primarily triggered a cytostatic response with characteristics consistent with activation of the TCS program (unpublished data cited in [30,72]).
