Three human breast cancer cell lines representing three different genetic backgrounds (MCF7/p53 wild-type; MCF7/p53 knockdown, and MDA-MB-468/p53 mutant) were exposed to various concentrations of the test compound (0, 1, 2.5, 5, 10, 25, and 50 μM) for 72 hrs, and cell survival percentages were determined. This evidence concerns the gene TP53 and breast carcinoma.
