PMBPs impaired the migration and invasion of ovarian cancer cells as assessed by transwell chamber assay.

A2780 and OV2008 cells were treated with PMBPs (0, 5, 10, 25 μg/ml) for 24 h. (A) Representative images of cells that migrated and invaded onto the underside of transwell membrane at 100× magnification under a microscope. (B,C) Number of cells of each field was counted and averaged. Invaded cells were expressed relative to that of control group. The experiments were repeated three times. **P<0.01 and ***P<0.001 compared to the control group.
