OFE suppressed the motility of cancer cells. a SRB assay was performed to assess the viability of SKOV3 cells in the presence of OFE. ** P < 0.01 vs. control; two-tailed Student’s t-tests. b Wound-healing assays were used to determine the effects of OFE or the DMSO vehicle on cancer cell motility. c The wound healing results were scored in a double-blind method analyzing several areas of the wound. d Transwell assays were also used to determine the effects of OFE or the DMSO vehicle on cancer cell motility. e Crystal violet was solubilized with 200-μL 10 % acetic acid per well, and the migratory rate was quantified by measuring the OD. Data are presented as mean ± SD from three independent experiments. ** P < 0.01 vs. control; ANOVA followed by LSD
