TP53 and ovarian carcinoma: Noticeably, MOAP-1 expression was detected in the p53-positive cell lines (U2OS, HCT116, ZR-75, IMR-32, and PANC1) but was reduced/absent in p53-null cells (SAOS-2 and SKOV3), p53 frameshift mutation or rearrangement cell lines (Caco-2 and CAPAN-2), and p53-mutant cell lines (SKBR3, MDA-MB-468, MDA MB-231,BT-549, and BT-20 (breast cancer cells) (Fig. 2D), and OVCAR-3 (ovarian cancer).
