dc.description.abstract | Elevated levels of cyclooxgenase-2 (COX-2) and matrix metalloproteinases (NMPs) are often observed in various types of cancerous and transformed cells, and hence recognized as potential molecular targets for the chemoprevention. In the present study, we investigated the possible inhibitory effects of curcumin on the expression of COX-2 and MMP-9 induced by the tumor promoter 12-O-tetradecanoylphorbol 13-acetate (TPA) in MCF10A human breast epithelial (MCF10A) cells and the underlying mechanisms. Curcumin inhibited the TPA-induced COX-2 expression at both transcriptional and post-transcriptional levels, and reduced the synthesis of prostaglandin E 25 one of the major products of COX-2. Likewise, curcumin attenuated invasiveness and motility of MCF10A cells stimulated with TPA through suppression of MNIP expression. Curcumin blocked TPA-induced activation of extracellular signal-regulated protein kinase (ERK1/2) and nuclear factor kappa B (NF-kappa B) transcriptional activity. Overexpression of the dominant negative forms of ERK2 abrogated the TPA-induced NF-kappa B transcriptional activity. Treatment of MCF10A cells with U0126, which is a pharmacological inhibitor of ERK1/2, reduced TPA-induced up-regulation of COX-2 and NMP-9. Taken together, these findings suggest that curcumin inhibits the TPA-induced up-regulation of COX-2 and MMP-9 by suppressing ERK1/2 phosphorylation and NF-kappa B trans-activation in human breast epithelial cells, which may contribute to its chemopreventive potential. | - |
