Overexpression of matrix metalloproteinases (MMPs) is associated with cancer metastasis. We assessed mRNA expression of MMPs in six human colorectal cancer cell lines and found a considerable level of MMP-7 expression in HT-29 cells. Next, we searched for natural and synthetic compounds that cause a reduction in the production of proMMP-7 protein, and found that nobiletin (NOB), quercetin, valeryl salicylate, and sulindac sulfone demonstrated marked inhibition. Importantly, NOB attenuated proMMP-7 protein and its mRNA expression both concentration- and time-dependently via a reduction of activator protein-1 (AP-1) DNA binding activity, suggesting it as a promising agent for suppression of cancer cell invasion and metastasis through MMP-7 gene repression.
