It has already shown strong antiproliferative, cytotoxic and pro-apoptotic activities against head and neck cancersand against breast, colorectal, lung and leukemia cancer cells. Ovarian cancer is one of the most dangerous gynecological cancers. Its treatment involves intensive chemotherapy with platinum saltsand paclitaxel (PTX) . The purpose of this study was to evaluate whether the combined use of CAPE and paclitaxel increases the effectiveness of chemotherapeutic agents. The experiment was performed on three ovarian cancer lines: OV7, HTB78, and CRL1572 . The effect of the tested compounds was assessed using H-E staining, a wound-healing test, MTT and the cell death detection ELISAPLUS test. The experiment proved that very low doses of PTX (10 nM) showed a cytotoxic effect against all the cell lines tested. Also, the selected doses of CAPE had a cytotoxic effect on the tested ovarian cancer cells. An increase in the cytotoxic effect was observed in the OV7 line after the simultaneous administration of 10 nM PTX and 100 􀀖M CAPE. The increase in the cytotoxicity was dependent on the CAPE dosage (50 vs. 100 􀀖M) and on the duration of the experiment. In the other cell lines tested, the cytotoxic effect of PTX did not increase after the CAPE administration. The administration of PTX together with CAPE increased the percentage of apoptotic cells in the tested ovarian cancer cell lines. Moreover, the simultaneous administration of PTX and CAPE enhanced the anti-migration activity of the chemotherapeutic used in this study.  \nKeywords: propolis; caffeic acid phenethyl ester; paclitaxel; ovarian cancer; apoptosis  \n1. Introduction  \nEach year, approximately 240,000 women worldwide are diagnosed with ovarian cancer (OC) . Ovarian cancer ranks as the second most common type of gynecological cancer and has a low survival rate. The incidence of ovarian tumors continues to increase. For every seventy women, one will develop ovarian cancer, and up to one in one hundred will die from the disease. The reason for such an unfavorable prognosis is the late diagnosis of the disease. Ovarian cancer does not give clinical symptoms for a long time, and the reported abdominal pain, fatigue and problems with urination are not specific [1,2] .  \nThe treatment of ovarian cancer involves multi-stage chemotherapy preceded by a complete surgical operation.
