Inhibition of MACC1 by RNAi suppressed the migration ability of ovarian carcinoma cells. Transwell migration assay was used for cell migration ability assay. (A): OVCAR-3 cells. (B): OVCAR-3-neo cells. (C): OVCAR-3-NC cells. (D): OVCAR-3-s3 cells (Hematoxylin staining, × 400). Each bar represents the cell numbers adherent on lower membrane.*P < 0.05 versus control groups.
