| Abstract: | Benzyl isothiocyanate (BITC), a component of dietary cruciferous vegetables, has antioxidant and
anticancer properties. In this study, we show for the first time the antimetastatic effects of BITC in
human colon cancer HT29 cells. BITC had an inhibitory effect on cell migration and invasion. Protein
levels of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and urokinaseplasminogen activator (u-PA) were reduced by BITC in a concentration-dependent manner. BITC
also exerted an inhibitory effect on phosphorylation of c-Jun N-terminal kinase 1 and 2 (JNK1/2),
extracellular signal-regulated kinases 1 and 2 (ERK1/2), phosphatidylinositol 3-kinase (PI3K) and
protein kinase C (PKC) that are upstream of nuclear factor kappa B (NF-κB). BITC inhibited DNA
binding activity of NF-κB. Moreover, BITC decreased the levels of c-Fos, c-Jun, Ras, FAK, PI3K and
GRB2 in HT29 cells. Reductions in the enzyme activity, protein and mRNA (mRNA) levels of MMP-2
were observed in BITC-treated HT29 cells. BITC also inhibited mRNA levels of MMP-2, -7, and -9 in
HT29 cells. Results from zymography showed that BITC treatment decreased MMP-2 expression in
a concentration-dependent manner. BITC inhibited PKCδ activity in HT29 cells. Furthermore,
inhibitors specific for JNK (SP600125) reduced expression of MMP-2, MMP-9, and u-PA. These
results demonstrated that BITC could alter HT29 cell metastasis by reduction of MMP-2, MMP-9,
and u-PA expression through the suppression of a PKC, MAPK signaling pathway and inhibition of
NF-κB levels. These findings suggest that BITC has potential as an antimetastatic agent. |
