In this study, we investigated whether olive leaf and oleuropein have the potential to stop cell motility, which a metastatic cell behavior by blocking voltage-gated sodium channels (VGSCs). For this purpose, it was first prepared the aqueous extract of olive leaves (AOLE). Then it was assayed the effect on the motility of MAT-LyLu, a highly metastatic Dunning rat prostate adenocarcinoma cells of this extract. The phenolic content of AOLE was analyzed using LC-MS/MS instrument. It was observed that oleuropein was the most finding compound in AOLE. Therefore, whether oleuropein was responsible for the inhibitory effect of AOLE on the MAT-LyLu cell movement was tested. Nontoxic oleuropein concentrations and those that did not affect proliferation on MAT-LyLu cells were determined. Subsequently, it was examined the effects of oleuropein on the lateral and vertical movement of MAT-LyLu cells. To elucidate the mechanism of oleuropein affecting cell motility, whether it suppressed mRNA expression of, which encodes the VGSC was analyzed. Accordingly, oleuropein suppressed the movement of MAT-LyLu cells by reducingmRNA expression. In conclusion, we report the first time that oleuropein might be considered as a potential antimetastatic agent for prostate cancer due to its blocking effect on VGSC-mediated cell motility.
