The effects of PMBPs on the viability of ovarian cancer cells and normal ovarian cells.

(A) Ovarian cancer cells A2780 and OV2008, and normal ovarian cells IOSE80 were treated with PMBPs (0, 10, 25, 50, 75, 100, 120 μg/ml) for 24 h or 48 h. The cells' viability at the various concentrations of PMBPs were detected by MTT assay and expressed relative to that of non-treated cells. The experiments were repeated three times. (B) Ovarian cancer cells A2780 and OV2008, and normal ovarian cells IOSE80 were treated with PMBPs (0, 25, 75, 100 μg/ml) for 24 h, and cells were photographed with inverted contrast microscopy (magnification, 40×).
