OBJECTIVE: Ovarian cancer is one of three malignant tumors of the female reproductive system. Our previous studies showed that the traditional Chinese medicine naringin significantly inhibited the proliferation of platinum-resistant ovarian cancer cells, and that the mechanism may be related to the NF-κB pathway.
METHODS: The MTT assay was used to detect the sensitivity of SKOV3 and SKOV3/CDDP cells to cisplatin, the effect of different naringin concentrations on the proliferation of SKOV3/CDDP cells, and the reversal of cisplatin resistance in naringin-treated SKOV3/CDDP cells. Western blotting was used to detectβ-catenin, c-Myc, and cyclin D1 protein levels in the different cell lines.
RESULTS: MTT results showed that different concentrations of naringin inhibited the proliferation of SKOV3 and SKOV3/CDDP cells, and that the inhibition increased with increasing concentrations and prolonged incubation times. Western blotting revealed that compared with controls (SKOV3/CDDP-0),β-catenin, c-Myc and cyclin D1 proteins levels were significantly decreased in SKOV3/CDDP-C, SKOV3/CDDP-N 20, and SKOV3/CDDP-CN 20 cells, suggesting that naringin inhibited the proliferation of SKOV3/CDDP cells in a concentration and time dependent manner.
CONCLUSIONS: Non-cytotoxic naringin reduced the expression ofβ-catenin, c-Myc, and cyclin D1 in SKOV3/CDDP cells and partially reversed cisplatin resistance in SKOV3/CDDP CN 20 cells.
