    Abstract:
    OBJECTIVE: To explore the effect of a Chinese medicine, Xiaoaiping, in combination with cisplatin on the proliferation, invasion and apoptosis in human ovarian cancer HO-8910PM cells in vitro and vivo. METHODS: CCK-8 assay was used to detect the inhibitoty effect of Xiaoaiping alone or in combination with cisplatin on the proliferation of human ovarian cancer HO-8910PM cells. Flow cytometry was used to detect the apoptosis and cell cycle distribution. Transwell migration test was used to assay the effect of drugs on the cell invasive capability. Changes of the tumor volume in nude mice were observed to evaluate the antitumor effects in vivo. RESULTS: CCK-8 assay Xiaoaiping alone or combined with cisplatin could inhibit the proliferation of HO-8910PM cells with a dose-dependent manner. The inhibition rates of Xiaoaiping combined with cisplatin were (53.4±3.0)%, significantly increased than those with single drug (P<0.05). Flow cytometry showed that G0/G1 fraction was increased respectively from (64.2±1.6)% to (74.1±1.6)% and (68.6±1.6)%. The percentages of apoptotic cells were increased from (2.2±1.6)% to (16.1±1.6)%, (35.6±1.6)% after treated with Xiaoaiping, Cisplatin and combination drugs (P<0.05 for all). Transwell chamber with matrigel assay showed that number of cells penetrating through membrane in HO-8910PM cells was (89.2±20.7)/HPF in the drug combination group, significantly less than that in the control group(187.2±24.6)/HPF, Xiaoaiping(141.8±13.7 )/HPF or cisplatin group (155.8±19.4)/HPF (P<0.01 for all). The inhibition rate of drug combination group in the nude mouse transplanted tumors, compared with that of single Xiaoaiping and cisplatin group, was increased significantly (59.0% vs. 23.4% and 34.2%), (P<0.01 for both). CONCLUSION: The results of our in vitro and vivo experiments indicate that Xiaoaiping can inhibit cell proliferation, increase G0/G1 arrest, promote apoptosis, inhibit cell migration of human ovarian cancer HO-8910 PM cells, and can synergistically enhance the antitumor activity of cisplatine.
