Abstract

Cell motility involves metastasis suppressors and other regulators that play an important role in tumor invasion and metastasis. Phenethyl isothiocyanate (PEITC), found in dietary cruciferous vegetables, has been found to exhibit antitumor properties and therefore is of special interest for the development of chemopreventive and chemotherapeutic agent for human cancers. Here, we report that in addition to its function as an anticancer agent, and PEITC can inhibit migration and invasion through the extracellular signal-regulated kinases 1/2 (ERK1/2), protein kinase C (PKC) and nuclear factor-kappaB (NF-kappaB) signaling pathways in human gastric cells. The results from wound healing and Boyden chamber assays (migration and invasion) assay indicated that PEITC exhibited an inhibitory effect on the migration and invasion of AGS cells. Results from Western blotting examination demonstrated that PEITC exerted an inhibitory effect on the ERK1/2, mitogen-activated protein kinase kinase 7 (MKK7), MAP kinase kinase kinase 3 (MEKK3), son of sevenless 1 (SOS1), PKC, Ras homolog gene family, member A (Rho A) and urokinase-type plasminogen activator (uPA), causing the inhibition of matrix metallopeptidase-2 (MMP-2) and -9 then followed by t...Continue Reading
