The expression of matrix metalloproteinase (MMPs)-9 is critical for cell migration and can lead to invasion and metastasis of cancer cells. In the present study, we examined the inhibitory effects of JNP3, a new compound which was isolated from traditional Chinese medicine, on cell invasion and MMP-9 activation in phorbol myristate acetate (PMA)-induced MCF-7 cells. Treatment with JNP3 significantly and selectively inhibited PMA-induced MMP-9 secretion, mRNA expression and protein levels, and these results led to reduction of cell invasion and migration in PMA-induced MCF-7 cells. The results of MMP-9 promoter assay and EMSA showed that JNP3 specifically inhibited PMA-induced MMP-9 gene expression by blocking NF-kappa B-dependent transcriptional activity. In addition, PMA-induced phosphorylation of ERK1/2 and JNK were suppressed by JNP3 treatment, whereas the phosphorylation of p38 MAPK was not affected by JNP3. These results suggest that JNP3 can be potential anti-cancer agents through specific inhibition of NF-kappa B-dependent MMP-9 gene expression. (C) 2012 Elsevier Inc. All rights reserved.
