1 MK-1775 synergized with CDDP to block proliferation, inducing apoptosis and mitotic catastrophe in TP53-mutant UC cells but not in TP53-wild-type cells. Cisplatin tumor protein p53 Homo sapiens
2 Knocking down TP53 in TP53-wild-type cells induced synergism of MK-1775 and CDDP. Cisplatin tumor protein p53 Homo sapiens
3 Knocking down TP53 in TP53-wild-type cells induced synergism of MK-1775 and CDDP. Cisplatin tumor protein p53 Homo sapiens
4 In UMUC3 cell xenografts and two patient-derived xenograft lines with MDM2 overexpression, in which the p53/cell cycle pathway was inactivated, AZD-1775 combined with CDDP suppressed tumor growth inducing both M-phase entry and apoptosis, whereas AZD-1775 alone was as effective as the combination in RT4 cell xenografts. Cisplatin tumor protein p53 Homo sapiens
5 Differential anti-tumor efficacy of WEE1 blockade alone or combined with CDDP may exist according to p53/cell cycle pathway activity, which may be predictable using an ex vivo 3D primary culture system. Cisplatin tumor protein p53 Homo sapiens
