Figure 4. Oxamate enhanced the tumor suppression effect of PARP inhibitors on ovarian cancer cells. (A–D) Tumor volumes of xenograft tumor with oxamate and/or PARP inhibitors (olaparib or AG14361) treatment. (E–H) Survival time of xenograft tumor models with oxamate and/or PARP inhibitors (olaparib or AG14361) treatment were recorded. Mean ± SEM, *P < 0.05, **P < 0.01, ns: no significance.
